本發明如今將以所示之發明之例示性實施例之參考附圖被描述更完整。The invention will now be described more fully hereinafter with reference to the accompanying drawings in the accompanying drawings.

第1圖為根據本發明之一實施例之可撓性顯示面板100的示意性透視圖，以及第2圖為顯示第1圖之沿圖中之線II-II之可撓性顯示面板100的剖面圖。1 is a schematic perspective view of a flexible display panel 100 according to an embodiment of the present invention, and FIG. 2 is a view showing a flexible display panel 100 along line II-II of FIG. 1 Sectional view.

參照第1圖及第2圖，可撓性顯示面板100包括定向於第一平面（x-y平面）的顯示區D，以及定向於不同於第一平面（x-y平面）之第二平面（y-z平面）且位於顯示區D之外的非顯示區N1、N2、N3及N4。非顯示區N1及N3越過顯示區D而於非顯示區N1、N2、N3及N4中互相面對而摺疊於-z方向至相反z方向中顯示顯示區D處。Referring to FIGS. 1 and 2, the flexible display panel 100 includes a display area D oriented in a first plane (xy plane) and a second plane (yz plane) oriented different from the first plane (xy plane). And non-display areas N1, N2, N3, and N4 located outside the display area D. The non-display areas N1 and N3 cross the display area D and face each other in the non-display areas N1, N2, N3, and N4, and are folded in the -z direction to the display area D in the opposite z direction.

因非顯示區N1及N3摺疊於-z方向至相反z方向中顯示顯示區D處，當使用者自顯示區D前方（z方向）看可撓性顯示面板100，使用者辨識非顯示區N1及N3摺疊的寬度W1為圍繞顯示區D左右側的邊界。Since the non-display areas N1 and N3 are folded in the -z direction to the display area D in the opposite z direction, when the user views the flexible display panel 100 from the front (z direction) of the display area D, the user recognizes the non-display area N1. And the width W 1 of the N3 fold is a boundary around the left and right sides of the display area D.

參照第2圖，因寬度W1於非顯示區N1及N3摺疊使得其遠小於非顯示區N1及N3摺疊之前的原始寬度W0，使用者辨識由非顯示區N1及N3形成之顯示區D的邊界大小是顯著的減小。當顯示區D的面積在非顯示區N1及N3摺疊之前後不變，非顯示區N1及N3與使用者辨識的顯示區D的面積比減小，因此，可見相對放大顯示區D的效果。因顯示區D的寬度可藉由降低非顯示區N1及N3的寬度（W0-W1）而被放大，當可撓性顯示面板100被應用為具有與可撓性顯示面板100相同規格的顯示裝置，可撓性顯示面板100可實現為相比於其他顯示面板較放大的影像螢幕。Referring to FIG. 2, since the width W 1 is folded in the non-display areas N1 and N3 so that it is much smaller than the original width W 0 before the folding of the non-display areas N1 and N3, the user recognizes the display area D formed by the non-display areas N1 and N3. The boundary size is significantly reduced. When the area of the display area D does not change after the non-display areas N1 and N3 are folded, the area ratio of the non-display areas N1 and N3 to the display area D recognized by the user is reduced, and therefore, the effect of relatively enlarging the display area D can be seen. Since the width of the display area D can be enlarged by reducing the width (W 0 -W 1 ) of the non-display areas N1 and N3, when the flexible display panel 100 is applied to have the same specifications as the flexible display panel 100 The display device, the flexible display panel 100 can be implemented as an image screen that is more enlarged than other display panels.

非顯示區N1及N3的摺疊寬度W1可藉由顯示區D及非顯示區N1及N3被摺疊的一部分的內曲率半徑R與可撓性顯示面板100的厚度T的總合而決定。即使描述如下，因顯示區D及非顯示區N1及N3被摺疊的一部分的內曲率半徑R與可撓性顯示面板100的厚度T可被顯著的減少，使用者可辨識顯示區D形成自非顯示區N1及N3為幾乎無邊界。The folding width W 1 of the non-display areas N1 and N3 can be determined by the sum of the inner radius of curvature R of the portion of the display area D and the non-display areas N1 and N3 folded and the thickness T of the flexible display panel 100. Even if the description is as follows, the inner radius of curvature R of the portion where the display area D and the non-display areas N1 and N3 are folded and the thickness T of the flexible display panel 100 can be significantly reduced, and the user can recognize that the display area D is formed from a non- The display areas N1 and N3 are almost borderless.

第3圖為作為第1圖之比較範例之無被摺疊的非顯示區N1、N2、N3及N4的平面顯示面板10的示意性透視圖，以及第4圖為顯示第3圖之沿圖中之線IV-IV之平面顯示面板10的剖面圖。3 is a schematic perspective view of the flat display panel 10 as the comparative non-display area N1, N2, N3, and N4 of the comparative example of FIG. 1, and FIG. 4 is a view showing the third figure. A cross-sectional view of the flat display panel 10 of line IV-IV.

參照第3圖及第4圖，無被摺疊的非顯示區N1、N2、N3及N4的平面顯示面板10包含顯示區D及顯示區D外的非顯示區N1、N2、N3及N4。Referring to FIGS. 3 and 4, the flat display panel 10 of the non-displayed non-display areas N1, N2, N3, and N4 includes the display area D and the non-display areas N1, N2, N3, and N4 outside the display area D.

因非顯示區N1、N2、N3及N4無被摺疊，當使用者自顯示區D前方（z方向）看平面顯示面板10，使用者辨識非顯示區N1及N3的原始寬度W0為圍繞顯示區D左右側的邊界。因此，使用者辨識顯示區D較厚的邊界形成自非顯示區N1及N2，對比於上述第1圖的可撓性顯示面板100。Since the non-display areas N1, N2, N3, and N4 are not folded, when the user views the flat display panel 10 from the front (z direction) of the display area D, the user recognizes the original width W 0 of the non-display areas N1 and N3 as a surrounding display. The boundary of the left and right sides of zone D. Therefore, the thicker boundary of the user identification display area D is formed from the non-display areas N1 and N2, compared to the flexible display panel 100 of the above-described first drawing.

當第1圖的可撓性顯示面板100的顯示區D及非顯示區N1及N3的面積與第3圖的平面顯示面板10的顯示區D及非顯示區N1及N3的面積相同時，使用者辨識第1圖的可撓性顯示面板100的非顯示區N1及N3與顯示區D的面積比減小，相比於其於相對的例示性的平面顯示面板10，因此可見放大的顯示螢幕的影響。When the areas of the display area D and the non-display areas N1 and N3 of the flexible display panel 100 of FIG. 1 are the same as the areas of the display area D and the non-display areas N1 and N3 of the flat display panel 10 of FIG. 3, the use is the same. It is recognized that the area ratio of the non-display areas N1 and N3 of the flexible display panel 100 of FIG. 1 to the display area D is reduced, and the enlarged display screen can be seen compared to the corresponding exemplary flat display panel 10. Impact.

根據比較範例，在平面顯示面板10的例子中，為了減少非顯示區N1及N3的面積，配置於非顯示區N1及N3中的各種電路或配線的數量必須減少，或者電路或配線的線寬必須減少。然而，因高影像品質及顯示裝置的各種應用的需求增加，電路或配線的數量減少受限。此外，降低電路或配線的線寬的製程係較困難地。然而，在第1圖的可撓性顯示面板100中，使用者辨識的非顯示區N1及N3的面積可被減少，不需降低配置於非顯示區N1及N3中的電路或配線的數量或線寬。According to the comparative example, in the example of the flat display panel 10, in order to reduce the area of the non-display areas N1 and N3, the number of various circuits or wirings disposed in the non-display areas N1 and N3 must be reduced, or the line width of the circuit or wiring Must be reduced. However, due to the increased demand for high image quality and various applications of display devices, the number of circuits or wiring is limited. In addition, the process of reducing the line width of the circuit or wiring is more difficult. However, in the flexible display panel 100 of FIG. 1, the area of the non-display areas N1 and N3 recognized by the user can be reduced, and the number of circuits or wirings disposed in the non-display areas N1 and N3 need not be reduced or Line width.

有機發光裝置120配置於顯示區D中。有機發光裝置120包含像素電極121、普遍層的相反電極123以及介於像素電極121與相反電極123中的有機發光層122。像素電極121為通電至配置於可撓性基板111上的薄膜電晶體。即使未顯示於第6圖，有機發光裝置120通電至至少一交換薄膜電晶體及儲存電容器，從而自顯示區D發光。The organic light emitting device 120 is disposed in the display area D. The organic light-emitting device 120 includes a pixel electrode 121, a counter electrode 123 of a general layer, and an organic light-emitting layer 122 interposed between the pixel electrode 121 and the opposite electrode 123. The pixel electrode 121 is electrically connected to a thin film transistor disposed on the flexible substrate 111. Even if not shown in FIG. 6, the organic light-emitting device 120 is energized to at least one of the exchange film transistors and the storage capacitor, thereby emitting light from the display region D.

光可發射自有機發光層122朝向可撓性基板111或可撓性封裝構件113。在現有實施例中，朝向可撓性封裝構件113顯示影像的上發光型顯示裝置被描述。然而本發明不受限於此，其可被應用於朝向可撓性基板111顯示影像的下發光型顯示裝置。在下發光型顯示裝置的例子中，非顯示區N1及N3被摺疊於方向相反於顯示影像的-z方向，亦即是，朝向可撓性封裝構件113（z方向）。Light may be emitted from the organic light emitting layer 122 toward the flexible substrate 111 or the flexible package member 113. In the prior embodiment, an upper emission type display device that displays an image toward the flexible package member 113 is described. However, the present invention is not limited thereto, and can be applied to a lower emission type display device that displays an image toward the flexible substrate 111. In the example of the lower emission type display device, the non-display areas N1 and N3 are folded in the -z direction opposite to the display image, that is, toward the flexible package member 113 (z direction).

提供影像訊號給配置於顯示區D的顯示裝置的各種電路（圖未示）及配線（圖未示）可被配置於非顯示區N1、N2、N3及N4中。Various circuits (not shown) and wirings (not shown) for providing image signals to the display device disposed in the display area D can be disposed in the non-display areas N1, N2, N3, and N4.

參照第5圖，提供電力給相反電極123的電極電力供給線131及電極電力供給線131的終端部分132配置於非顯示區N1、N2、N3及N4中。傳送驅動訊號給顯示區D的掃瞄電路單元133及掃瞄電路單元133的終端部分134配置於非顯示區N1及N2中。傳送數據訊號給顯示區D的數據電路單元135及數據電路單元135的終端部分136配置於非顯示區N2及N3中。提供驅動力給顯示區D的驅動力配線單元137及驅動力配線單元137的終端部分138配置於非顯示區N2中。配置於終端部分132、134、136及138的銲墊單元P位於非顯示區N2中。Referring to Fig. 5, the electrode power supply line 131 for supplying the electric power to the opposite electrode 123 and the terminal portion 132 of the electrode power supply line 131 are disposed in the non-display areas N1, N2, N3, and N4. The drive driving signal is supplied to the scanning circuit unit 133 of the display area D and the terminal portion 134 of the scanning circuit unit 133 in the non-display areas N1 and N2. The data circuit unit 135 for transmitting the data signal to the display area D and the terminal portion 136 of the data circuit unit 135 are disposed in the non-display areas N2 and N3. The driving force wiring unit 137 that supplies the driving force to the display area D and the terminal portion 138 of the driving force wiring unit 137 are disposed in the non-display area N2. The pad unit P disposed in the terminal portions 132, 134, 136, and 138 is located in the non-display area N2.

顯示於第5圖中的各種電路、配線及終端部分只是非顯示區N1、N2、N3及N4的例示性說明。換句話說，明顯地，配置於非顯示區N1、N2、N3及N4中的各種電路、配線及終端部分可具有與第5圖不同的結構。The various circuits, wiring, and terminal portions shown in FIG. 5 are merely illustrative illustrations of non-display areas N1, N2, N3, and N4. In other words, it is obvious that various circuits, wirings, and terminal portions disposed in the non-display areas N1, N2, N3, and N4 may have a different configuration from that of FIG.

封裝至少顯示區D的可撓性封裝構件113可配置於顯示區D及非顯示區N1、N2、N3及N4中。可撓性封裝構件113可為封裝薄層。封裝薄層可具有包含多重無機絕緣層的結構，或無機絕緣層與有機絕緣層交替相疊的結構。The flexible package member 113 encapsulating at least the display area D may be disposed in the display area D and the non-display areas N1, N2, N3, and N4. The flexible package member 113 can be a thin layer of package. The encapsulating thin layer may have a structure including a plurality of inorganic insulating layers, or a structure in which an inorganic insulating layer and an organic insulating layer are alternately stacked.

第一保護薄膜114可位於可撓性基板111的一側。即使未顯示，黏著劑可被進一步注射於可撓性基板111與第一保護薄膜114之間。第二保護薄膜115可位於可撓性封裝構件113的一側。黏著劑可進一步注射於可撓性封裝構件113與第二保護薄膜115之間。The first protective film 114 may be located on one side of the flexible substrate 111. Even if not shown, the adhesive can be further injected between the flexible substrate 111 and the first protective film 114. The second protective film 115 may be located on one side of the flexible package member 113. The adhesive may be further injected between the flexible package member 113 and the second protective film 115.

第一保護薄膜114及第二保護薄膜115可具有相同的材料屬性並有助於改善可撓性顯示面板100的機械強度。第一保護薄膜114及第二保護薄膜115可由可撓性材料形成。The first protective film 114 and the second protective film 115 may have the same material properties and contribute to improvement in mechanical strength of the flexible display panel 100. The first protective film 114 and the second protective film 115 may be formed of a flexible material.

此外，第一保護薄膜114及第二保護薄膜115之至少其一可具有偏光功能。在此，具有偏光功能的保護薄膜的排列可由有機發光裝置120發射光的方向而決定。舉例來說，當有機發光裝置120為發射光朝向第二保護薄膜115以顯示影像的上發光型顯示裝置，第二保護薄膜115配置為具有偏光功能。同時，當有機發光裝置120為發射光朝向第一保護薄膜114以顯示影像的下發光型顯示裝置，第一保護薄膜114配置為具有偏光功能。此外，當有機發光裝置120上及下發光型顯示裝置，第一保護薄膜114及第二保護薄膜115皆可具有偏光功能。In addition, at least one of the first protective film 114 and the second protective film 115 may have a polarizing function. Here, the arrangement of the protective film having the polarizing function can be determined by the direction in which the organic light-emitting device 120 emits light. For example, when the organic light-emitting device 120 is an upper-light-emitting display device that emits light toward the second protective film 115 to display an image, the second protective film 115 is configured to have a polarizing function. Meanwhile, when the organic light-emitting device 120 is a lower-light-emitting type display device that emits light toward the first protective film 114 to display an image, the first protective film 114 is configured to have a polarizing function. In addition, when the organic light-emitting device 120 and the lower light-emitting display device, the first protective film 114 and the second protective film 115 may have a polarizing function.

第8圖為根據第1圖的比較性範例，在平面顯示面板20被彎曲之前後的示意性剖面圖。Fig. 8 is a schematic cross-sectional view after the flat display panel 20 is bent according to the comparative example of Fig. 1.

當第二保護薄膜115具有偏光功能，根據相關技術，第一保護薄膜114設置以完整覆蓋可撓性基板111，而第二保護薄膜115設置以只有完整覆蓋顯示區D，如第8圖所示。When the second protective film 115 has a polarizing function, according to the related art, the first protective film 114 is disposed to completely cover the flexible substrate 111, and the second protective film 115 is disposed to completely cover the display area D, as shown in FIG. .

在此情況下，當平面顯示面板20被彎曲於非顯示區N1及N3中，彎曲力矩(bending moment)在包含第二保護薄膜115的部分及不包含第二保護薄膜115的部分之間變化。因此，裂縫可發生在金屬層如各種電路及配線被形成的區域C中，在包含第二保護薄膜115的部分及不包含第二保護薄膜115的部分之間以形成非顯示區N1及N3。裂縫可引發平面顯示面板20的不正常光，其可成為缺點的原因。In this case, when the flat display panel 20 is bent in the non-display areas N1 and N3, the bending moment varies between the portion including the second protective film 115 and the portion not including the second protective film 115. Therefore, cracks may occur in a region C in which metal layers such as various circuits and wirings are formed, between portions including the second protective film 115 and portions not including the second protective film 115 to form non-display regions N1 and N3. The crack can cause abnormal light of the flat display panel 20, which can be a cause of the disadvantage.

為了避免此問題，在現有實施例中，第一保護薄膜114及第二保護薄膜設置以覆蓋可撓性顯示面板100-B的顯示區及非顯示區N1及N3。第一保護薄膜114及第二保護薄膜115可設置為互相對稱。舉例來說，第一保護薄膜114可設置以覆蓋可撓性基板111的兩端，而第二保護薄膜115可撓性封裝構件113的兩端。In order to avoid this problem, in the prior embodiment, the first protective film 114 and the second protective film are disposed to cover the display area and the non-display areas N1 and N3 of the flexible display panel 100-B. The first protective film 114 and the second protective film 115 may be disposed to be symmetrical to each other. For example, the first protective film 114 may be disposed to cover both ends of the flexible substrate 111, and the second protective film 115 may be flexible at both ends of the package member 113.

透過上述結構，相同的彎曲力矩可應用於金屬層如各種電路及配線的區域，以形成摺疊於非顯示區N1及N3與顯示區D的邊界的非顯示區N1及N3，以避免形成金屬層區域的損害或裂縫。Through the above structure, the same bending moment can be applied to a metal layer such as various circuits and wiring regions to form non-display areas N1 and N3 folded at the boundary between the non-display areas N1 and N3 and the display area D to avoid formation of a metal layer. Damage or crack in the area.

因組成可撓性顯示面板100的可撓性基板111為可撓性的，其很難直接在可撓性基板111上形成顯示區D與非顯示區N1。因此，即使未顯示，可撓性顯示面板100的方法包括：形成可撓性基板111於具剛性之玻璃基板上（圖未示）；形成屏障層112於可撓性基板111之上；形成顯示區D與非顯示區N1及N3於屏障層112之上；形成可撓性封裝構件113以覆蓋顯示區D；藉由第二黏著劑（圖未示）在可撓性封裝構件113貼上第二保護薄膜；自可撓性基板111分離玻璃基板（圖未示）；以及藉由第一黏著劑（圖未示）在可撓性基板111貼上第一保護薄膜114。Since the flexible substrate 111 constituting the flexible display panel 100 is flexible, it is difficult to form the display region D and the non-display region N1 directly on the flexible substrate 111. Therefore, even if not shown, the method of the flexible display panel 100 includes: forming a flexible substrate 111 on a rigid glass substrate (not shown); forming a barrier layer 112 on the flexible substrate 111; forming a display The region D and the non-display regions N1 and N3 are over the barrier layer 112; the flexible package member 113 is formed to cover the display region D; and the flexible package member 113 is attached by a second adhesive (not shown). a second protective film; a glass substrate (not shown) is separated from the flexible substrate 111; and a first protective film 114 is attached to the flexible substrate 111 by a first adhesive (not shown).

根據現有實施例，第一保護薄膜114及第二保護薄膜115可應用於如下所述之本發明的其他實施例。According to the prior embodiment, the first protective film 114 and the second protective film 115 can be applied to other embodiments of the present invention as described below.

當第5圖的可撓性顯示面板100-B的顯示區D左右側的非顯示區N1及N3摺疊於-z方向，相反於顯示顯示區D的方向（z方向，如第1圖），繪示於第1圖及第2圖的可撓性顯示面板100被組成。The non-display areas N1 and N3 on the left and right sides of the display area D of the flexible display panel 100-B of FIG. 5 are folded in the -z direction, and opposite to the display display area D (z direction, as shown in FIG. 1). The flexible display panel 100 shown in FIGS. 1 and 2 is composed.

在可撓性顯示面板100中，當非顯示區N1及N3被折疊，一曲面可在顯示區D及非顯示區N1及N3的邊界被形成。In the flexible display panel 100, when the non-display areas N1 and N3 are folded, a curved surface can be formed at the boundary between the display area D and the non-display areas N1 and N3.

返回參照第2圖，邊界區RB包括介於顯示區D（第一區域RI）與非顯示區N3（第二區域RII）之間之一預定曲面。邊界區RB形成為具有內曲率半徑R的曲面。Referring back to FIG. 2, the boundary region RB includes a predetermined curved surface between the display region D (first region RI) and the non-display region N3 (second region RII). The boundary region RB is formed as a curved surface having an inner radius of curvature R.

在現有實施例中，第二區域RII的非顯示區N3延伸自邊界區RB。當使用者看摺疊於顯示區D前方（z方向）的可撓性顯示面板100，使用者自顯示區D的前方辨識非顯示區N3的寬度W1為顯示區D及非顯示區N3折疊部分的曲率半徑R與可撓性顯示面板100的厚度T的總和。在現有實施例中，使用者辨識的非顯示區N3的寬度W1與邊界區RB相同。In the prior embodiment, the non-display area N3 of the second region RII extends from the boundary area RB. When the user looks at the flexible display panel 100 folded in front of the display area D (z direction), the user recognizes the width W 1 of the non-display area N3 from the front of the display area D as the folded portion of the display area D and the non-display area N3. The sum of the radius of curvature R and the thickness T of the flexible display panel 100. In the prior embodiment, the width W 1 of the non-display area N3 recognized by the user is the same as the boundary area RB.

可撓性顯示面板100的厚度T可選擇自數十微米（μm）至數百微米（μm）的範圍內。特別地，於此，在小型的顯示裝置中，可撓性顯示面板的厚度可選擇自比上述範圍狹窄的範圍，使用者辨識非顯示區的寬度W1可更減少。明顯地，本發明不受限於上述的厚度範圍，如有需要可選擇比上述較寬的厚度範圍。The thickness T of the flexible display panel 100 can be selected from the range of several tens of micrometers (μm) to several hundred micrometers (μm). In particular, in the small display device, the thickness of the flexible display panel can be selected from a range narrower than the above range, and the user can recognize that the width W 1 of the non-display area can be further reduced. Obviously, the invention is not limited to the thickness range described above, and a wider thickness range than the above may be selected if desired.

第9圖顯示顯示區D及非顯示區N3摺疊部分的內曲率半徑R與使用者辨識的非顯示區N3的寬度W2及W3之間的關係。Fig. 9 shows the relationship between the inner radius of curvature R of the folded portion of the display area D and the non-display area N3 and the widths W 2 and W 3 of the non-display area N3 recognized by the user.

參照第9圖，當假設可撓性顯示面板100的厚度T是固定的及非顯示區N3摺疊以至於邊界區RB具有曲率半徑R2，使用者辨識非顯示區N3的寬度W2為曲率半徑R2與可撓性顯示面板100的厚度T的總和（W2= R2+ T）。當非顯示區N3摺疊以至於邊界區RB具有比曲率半徑R2較大的曲率半徑R3，使用者辨識非顯示區N3的寬度W3為可撓性顯示面板的曲率半徑R3與厚度T的總和。換句話說，當曲率半徑增加（R3> R2），使用者辨識非顯示區N3的寬度W3增加。Referring to FIG. 9, when it is assumed that the thickness T of the flexible display panel 100 is fixed and the non-display area N3 is folded such that the boundary area RB has a radius of curvature R 2 , the user recognizes that the width W 2 of the non-display area N3 is a radius of curvature. The sum of R 2 and the thickness T of the flexible display panel 100 (W 2 = R 2 + T). When the non-display area N3 is folded so that the boundary region than the curvature radius RB having a larger radius of curvature R 2 R 3, user identification of the non-display region N3 width W 3 of the flexible display panel radius of curvature R 3 and the thickness T Sum. In other words, as the radius of curvature increases (R 3 > R 2 ), the user recognizes that the width W 3 of the non-display area N3 increases.

顯示區D及非顯示區N3摺疊部分的內曲率半徑可介於0.01毫米與10毫米之間。當此部分的內曲率半徑由於彎曲應力小於0.01毫米，可撓性顯示面板100可不維持在摺疊狀態，以及當此部分的內曲率半徑大於10毫米，非顯示區N3的寬度W3增加。特別地，在此例中的小型顯示裝置，曲率半徑的範圍可選擇小於1毫米以至於使用者辨識非顯示區N3的寬度W3可更減小。The inner radius of curvature of the folded portion of the display area D and the non-display area N3 may be between 0.01 mm and 10 mm. When the inner radius of curvature of this portion is less than 0.01 mm due to the bending stress, the flexible display panel 100 may not be maintained in the folded state, and when the inner radius of curvature of this portion is larger than 10 mm, the width W 3 of the non-display area N3 is increased. In particular, in the small display device in this example, the radius of curvature may be selected to be less than 1 mm so that the user can recognize that the width W 3 of the non-display area N3 can be further reduced.

參照第10圖，第一區域RI的顯示區D延伸自邊界區RB。當使用者看可撓性顯示面板100摺疊於顯示區D前方，使用者辨識非顯示區N3的寬度W4為0。因此，在現有實施例中，使用者可辨識非顯示區N3為幾乎無邊界的。Referring to Fig. 10, the display area D of the first area RI extends from the boundary area RB. When the user sees that the flexible display panel 100 is folded in front of the display area D, the user recognizes that the width W 4 of the non-display area N3 is zero. Therefore, in the prior embodiment, the user can recognize that the non-display area N3 is almost borderless.

參照第11圖，第一區域RI的顯示區D及第二區域RII的非顯示區N3皆可配置於邊界區RB中。在這方面，如第10圖所示，使用者辨識非顯示區N3的寬度W5大於使用者辨識非顯示區N3的寬度W4，且如第2圖所示小於使用者辨識非顯示區N3的寬度W1。然而，即使在此例中，使用者辨識非顯示區N3的寬度W5為小於其於第3圖及第4圖的平面顯示面板10的無摺疊非顯示區N1及N3。Referring to FIG. 11, the display area D of the first area RI and the non-display area N3 of the second area RII may be disposed in the boundary area RB. In this regard, as shown in FIG. 10, the width W 5 of the user identification non-display area N3 is greater than the width W 4 of the user identification non-display area N3, and is smaller than the user identification non-display area N3 as shown in FIG. The width of W 1 . However, even in this example, the user recognizes that the width W 5 of the non-display area N3 is smaller than the unfolded non-display areas N1 and N3 of the flat display panel 10 of FIGS. 3 and 4.

在第1圖的可撓性顯示面板100的例子中，非顯示區N1及N3摺疊於顯示區D的左右側。然而，本發明不受限於此。換句話說，本發明的精神也應用於任何摺疊的非顯示區N1及N3。In the example of the flexible display panel 100 of FIG. 1, the non-display areas N1 and N3 are folded on the left and right sides of the display area D. However, the invention is not limited thereto. In other words, the spirit of the present invention is also applied to any folded non-display areas N1 and N3.

第12圖為根據本發明之另一實施例之可撓性顯示面板200的示意性透視圖，第13圖為顯示第12圖之沿圖中之線XIII-XIII之可撓性顯示面板200的剖面圖，以及第14圖為第12圖之非顯示區N2及N4在摺疊之前之可撓性顯示面板220-B之一例示性的示意性俯視圖。Figure 12 is a schematic perspective view of a flexible display panel 200 according to another embodiment of the present invention, and Figure 13 is a view showing a flexible display panel 200 of the line XIII-XIII along the line of Figure 12; The cross-sectional view, and Fig. 14, is an illustrative schematic top view of one of the flexible display panels 220-B of the non-display areas N2 and N4 of Fig. 12 prior to folding.

以下，現有實施例將描述關於第1圖與第12圖之不同。Hereinafter, the prior embodiment will describe the difference between the first figure and the twelfth figure.

參照第14圖，根據現有實施例的可撓性顯示面板200-B，在顯示區D上下側的非顯示區N2及N4摺疊於-z方向，相反於顯示顯示區D的方向（z方向）。其結果根據本發明的另一實施例的可撓性顯示面板200顯示於第12圖中。Referring to Fig. 14, according to the flexible display panel 200-B of the prior embodiment, the non-display areas N2 and N4 on the upper and lower sides of the display area D are folded in the -z direction, and the direction (z direction) of the display display area D is opposite. . As a result, the flexible display panel 200 according to another embodiment of the present invention is shown in FIG.

參照第12圖及第13圖，可撓性顯示面板200包含顯示區D及顯示區D外的非顯示區N1、N2、N3及N4。在非顯示區N1、N2、N3及N4中越過顯示區D而互相面對的非顯示區N2及N4摺疊於-z方向，相反於顯示顯示區的z方向。Referring to FIGS. 12 and 13, the flexible display panel 200 includes display areas D and non-display areas N1, N2, N3, and N4 outside the display area D. The non-display areas N2 and N4 that face each other across the display area D in the non-display areas N1, N2, N3, and N4 are folded in the -z direction, and are opposite to the z direction of the display area.

因非顯示區N2及N4摺疊於-z方向，相反於顯示顯示區的z方向，當使用者自顯示區D前方（z方向）看可撓性顯示面板200，使用者辨識非顯示區N2及N4摺疊的寬度W6為圍繞顯示區上下側的邊界。Since the non-display areas N2 and N4 are folded in the -z direction, and opposite to the z direction of the display area, when the user views the flexible display panel 200 from the front (z direction) of the display area D, the user recognizes the non-display area N2 and The width W 6 of the N4 fold is a boundary around the upper and lower sides of the display area.

如上所述，由於非顯示區N2及N4摺疊的寬度W6變得遠小於原先非顯示區N2及N4摺疊的寬度W0，使用者自非顯示區N2及N4辨識顯示區D的邊界顯著地減少。特別地，由於位於銲墊單元P的非顯示區N2的面積很大，位於銲墊單元P的非顯示區N2摺疊以便使用者辨識形成自非顯示區N2的顯示區D的邊界顯著的減少。As described above, since the width W 6 of the non-display areas N2 and N4 is much smaller than the width W 0 of the original non-display area N2 and N4, the user distinguishes the boundary of the display area D from the non-display areas N2 and N4 remarkably. cut back. In particular, since the area of the non-display area N2 of the pad unit P is large, the non-display area N2 located in the pad unit P is folded so that the user recognizes a significant decrease in the boundary of the display area D formed from the non-display area N2.

第15圖為根據第12圖修改之範例之可撓性顯示面板200-1的示意性透視圖，以及第16圖為顯示第14圖之沿圖中之線XVI-XVI之可撓性顯示面板200-1的剖面圖。15 is a schematic perspective view of a flexible display panel 200-1 according to an example modified according to FIG. 12, and FIG. 16 is a flexible display panel showing a line XVI-XVI of FIG. 14 along the figure. Sectional view of 200-1.

參照第15圖及第16圖，繪示於第12圖，且非顯示區N2的銲墊單元P所在之可撓性顯示面板200的非顯示區N22再一次摺疊向可撓性顯示面板200-1的內側。15 and FIG. 16, which are shown in FIG. 12, and the non-display area N22 of the flexible display panel 200 where the pad unit P of the non-display area N2 is located is once again folded toward the flexible display panel 200- The inside of 1 .

由於外部驅動器（圖未示）必須安裝於銲墊單元P或連接器C必須連接於銲墊單元P，當外部驅動器安裝於或連接器C電性連接於第12圖及第13圖狀態的銲墊單元P，使用者辨識顯示區N2的寬度W6增加，相較於第12圖的可撓性顯示面板200的非顯示區N2的寬度W6。Since the external driver (not shown) must be mounted on the pad unit P or the connector C must be connected to the pad unit P, when the external driver is mounted or the connector C is electrically connected to the welding of the state of FIG. 12 and FIG. the pad unit P, the width W of the user identification display area N2 is 6 increases, the non-display area as compared to the flexible display panel 200 of FIG. 12, a width W 6 of N2.

然而，如現有修改的範例中，當位於銲墊單元P的非顯示區N2的區域N22再一次摺疊向可撓性顯示面板200-1的內側，外部驅動器或連接器C配置於可撓性顯示面板200-1的內側以至於使用者辨識的非顯示區N2的寬度W6不改變。However, as in the prior modified example, when the region N22 located in the non-display area N2 of the pad unit P is once again folded toward the inner side of the flexible display panel 200-1, the external driver or connector C is disposed on the flexible display The inner side of the panel 200-1 so that the width W 6 of the non-display area N2 recognized by the user does not change.

即使在上述實施例中銲墊單元P設置於摺疊的非顯示區N22，本發明的態樣不限於此。亦即，上述各種電路及配線可配置於摺疊的非顯示區N22中。第17圖為根據本發明之另一實施例之可撓性顯示面板300的示意性透視圖，第18圖為顯示第17圖之沿圖中之線XVIII-XVIII之可撓性顯示面板300的剖面圖，以及第19圖為第17圖之非顯示區N1、N2、N3及N4在被摺疊之前之可撓性顯示面板300-B之一範例的示意性俯視圖。Even in the above embodiment, the pad unit P is disposed in the folded non-display area N22, and the aspect of the invention is not limited thereto. That is, the various circuits and wiring described above may be disposed in the folded non-display area N22. 17 is a schematic perspective view of a flexible display panel 300 according to another embodiment of the present invention, and FIG. 18 is a view showing a flexible display panel 300 along the line XVIII-XVIII of FIG. The cross-sectional view, and Fig. 19 is a schematic plan view of an example of the flexible display panel 300-B before the non-display areas N1, N2, N3, and N4 of Fig. 17 are folded.

以下，現有實施例將描述關於第1圖、第12圖及第17圖之實施例的不同。Hereinafter, the prior embodiment will describe differences with respect to the embodiments of Figs. 1, 12, and 17.

參照第19圖，根據現有實施例的可撓性顯示面板300-B中，在顯示區D上下左右側的非顯示區N1、N2、N3及N4摺疊於-z方向，相反於顯示顯示區D的方向（z方向）。其結果是根據本發明的現有實施例所建構的可撓性顯示面板300，如第17圖所示。Referring to Fig. 19, in the flexible display panel 300-B according to the prior embodiment, the non-display areas N1, N2, N3, and N4 on the upper, lower, left, and right sides of the display area D are folded in the -z direction, and opposite to the display display area D. Direction (z direction). The result is a flexible display panel 300 constructed in accordance with the prior embodiment of the present invention, as shown in FIG.

參照第17圖及第18圖，可撓性顯示面板300包含顯示區D及顯示區外的非顯示區N1、N2、N3及N4。互相面對的非顯示區N1、N2、N3及N4越過顯示區D在上下左右側摺疊於-z方向，相反於顯示顯示區D的方向（z方向）。Referring to FIGS. 17 and 18, the flexible display panel 300 includes a display area D and non-display areas N1, N2, N3, and N4 outside the display area. The non-display areas N1, N2, N3, and N4 facing each other are folded over the display area D in the -z direction on the upper, lower, left and right sides, and opposite to the direction (z direction) in which the display area D is displayed.

由於非顯示區N1、N2、N3及N4摺疊於-z方向，相反於顯示顯示區的z方向，當使用者自顯示區D前方（z方向）看可撓性顯示面板300，使用者辨識非顯示區N1、N2、N3及N4摺疊的寬度W7為圍繞顯示區D上下左右側的邊界。Since the non-display areas N1, N2, N3, and N4 are folded in the -z direction, and opposite to the z direction of the display area, when the user views the flexible display panel 300 from the front (z direction) of the display area D, the user recognizes the non-display area. The width W 7 of the folding of the display areas N1, N2, N3, and N4 is a boundary around the upper, lower, left, and right sides of the display area D.

如上所述，因非顯示區N1、N2、N3及N4摺疊的寬度W7變得遠小於非顯示區N1、N2、N3及N4摺疊之前的原先寬度W0，使用者自非顯示區N1、N2、N3及N4辨識顯示區D的邊界為顯著地減少。特別地，由於銲墊單元P1、P2、P3及P4分別所在之非顯示區N1、N2、N3及N4的面積很大，分別設置銲墊單元P1、P2、P3、P4的非顯示區N1、N2、N3及N4摺疊因而使使用者所辨識之自非顯示區所形成之顯示區D的邊界顯著地減少。As described above, since the width W 7 of the folding of the non-display areas N1, N2, N3, and N4 becomes much smaller than the original width W 0 before the folding of the non-display areas N1, N2, N3, and N4, the user is from the non-display area N1. N2, N3, and N4 recognize that the boundary of display area D is significantly reduced. In particular, since the areas of the non-display areas N1, N2, N3, and N4 where the pad units P1, P2, P3, and P4 are respectively located are large, the non-display areas N1 of the pad units P1, P2, P3, and P4 are respectively disposed. The N2, N3, and N4 folds thus significantly reduce the boundaries of the display area D formed by the user from the non-display area.

第20圖為根據第17圖修改之一範例之可撓性顯示面板300-1的示意性透視圖，以及第21圖為顯示第20圖之沿圖中之線XXI-XXI之可撓性顯示面板300-1的剖面圖。Fig. 20 is a schematic perspective view of a flexible display panel 300-1 according to an example of modification of Fig. 17, and Fig. 21 is a flexible display showing a line XXI-XXI along the figure of Fig. 20. A cross-sectional view of panel 300-1.

參照第20圖及第21圖，繪示於第17圖，且非顯示區N1、N2、N3及N4的銲墊單元P1、P2、P3及P4所在之可撓性顯示面板300的非顯示區N12及N32再一次折疊向可撓性顯示面板300-1的內側。Referring to FIGS. 20 and 21, the non-display area of the flexible display panel 300 in which the pad units P1, P2, P3, and P4 of the non-display areas N1, N2, N3, and N4 are located is shown in FIG. N12 and N32 are again folded toward the inner side of the flexible display panel 300-1.

由於外部驅動器（圖未示）必須安裝於各個銲墊單元P1、P2、P3及P4，或連接器C必須電性連接各個銲墊單元P1、P2、P3及P4，當外部驅動器安裝於或連接器C電性連接於在第17圖與第18圖狀態的各個銲墊單元P1、P2、P3及P4，使用者辨識之非顯示區N1、N2、N3及N4的寬度W7增加。Since the external driver (not shown) must be mounted on each pad unit P1, P2, P3, and P4, or the connector C must be electrically connected to each pad unit P1, P2, P3, and P4, when the external driver is mounted or connected The device C is electrically connected to the respective pad units P1, P2, P3, and P4 in the state of FIGS. 17 and 18, and the width W 7 of the non-display areas N1, N2, N3, and N4 recognized by the user is increased.

然而，如現有修改之範例，當銲墊單元P1、P2、P3及P4分別所在之非顯示區N1、N2、N3及N4的非顯示區N12及N32再一次摺疊向可撓性顯示面板300-1的內側，外部驅動器或連接器C係配置於可撓性顯示面板300-1的內側，以使使用者辨識之非顯示區N1、N2、N3及N4的寬度W7固定。However, as in the prior modified example, when the non-display areas N12 and N32 of the non-display areas N1, N2, N3, and N4 where the pad units P1, P2, P3, and P4 are respectively located are folded again toward the flexible display panel 300- The inner side of the first drive unit or the connector C is disposed inside the flexible display panel 300-1 so that the width W 7 of the non-display areas N1, N2, N3, and N4 recognized by the user is fixed.

即使在上述實施例中，銲墊單元P1、P2、P3及P4設置於折疊的非顯示區N12及N32中，本發明的態樣不限於此。亦即，各個上述之電路及配線可設置於折疊的非顯示區N12及N32中。Even in the above embodiment, the pad units P1, P2, P3, and P4 are disposed in the folded non-display areas N12 and N32, and the aspect of the invention is not limited thereto. That is, each of the above-described circuits and wirings may be disposed in the folded non-display areas N12 and N32.

第22圖為根據本發明之另一實施例之可撓性顯示面板結合之觸控面板400的剖面圖，第23圖為顯示在第22圖之可撓性顯示面板結合之觸控面板400之非顯示區N1及N3摺疊之前之可撓性顯示面板結合之觸控面板400-B的剖面圖，以及第24圖為顯示第23圖之可撓性顯示面板結合之觸控面板400-B的分解透視圖。Figure 22 is a cross-sectional view showing a touch panel 400 in combination with a flexible display panel according to another embodiment of the present invention, and Figure 23 is a view showing a touch panel 400 in combination with the flexible display panel of Figure 22; A cross-sectional view of the touch panel 400-B combined with the flexible display panel before the folding of the non-display area N1 and N3, and a touch panel 400-B of the flexible display panel shown in FIG. Decompose the perspective.

以下，現有實施例將描述實施例第1圖、第12圖、第17圖及第21圖之各方面不同。Hereinafter, the prior art will describe various aspects of the first, twelfth, seventeenth and twenty-first embodiments of the embodiment.

參照第22圖，根據本發明之現有實施例，可撓性顯示面板結合之觸控面板400藉由安裝觸控面板140於顯示於第1圖之可撓性顯示面板100所建構。Referring to FIG. 22, in accordance with a prior embodiment of the present invention, a touch panel 400 incorporating a flexible display panel is constructed by mounting the touch panel 140 on the flexible display panel 100 shown in FIG.

參照第23圖及第24圖，觸控面板140包含觸控區域RT及觸控區域RT外的配線區域T1、T2、T3及T4。根據現有實施例，觸控面板140可使用各種觸控方法如電容疊加、電阻膜或其類似方法。Referring to FIGS. 23 and 24 , the touch panel 140 includes a touch area RT and wiring areas T1 , T2 , T3 , and T4 outside the touch area RT . According to the prior embodiment, the touch panel 140 can use various touch methods such as a capacitance stack, a resistive film, or the like.

在非顯示區摺疊之前的可撓性顯示面板100-B包含顯示區D及顯示區外的非顯示區N1、N2、N3及N4。The flexible display panel 100-B before folding in the non-display area includes the display area D and the non-display areas N1, N2, N3, and N4 outside the display area.

觸控面板140的觸控區域RT及可撓性顯示面板100-B的顯示區D彼此對齊以互相對應以至於觸控面板140及可撓性顯示面板100-B可相互結合。The touch area RT of the touch panel 140 and the display area D of the flexible display panel 100-B are aligned with each other so that the touch panel 140 and the flexible display panel 100-B can be coupled to each other.

在可撓性顯示面板100-B與觸控面板140結合中，位於顯示區D左右側的可撓性顯示面板100-B的非顯示區N1及N3摺疊於-z方向，相反於顯示顯示區D的z方向。其結果建構顯示於第22圖的可撓性顯示面板結合的觸控面板400。In the combination of the flexible display panel 100-B and the touch panel 140, the non-display areas N1 and N3 of the flexible display panel 100-B located on the left and right sides of the display area D are folded in the -z direction, opposite to the display display area. The z direction of D. As a result, the touch panel 400 combined with the flexible display panel shown in FIG. 22 is constructed.

由於非顯示區N1及N3與觸控面板140的配線區域T1及T3摺疊於-z方向，相反於顯示顯示區D的z方向，當使用者自顯示區前方（z方向）看可撓性顯示面板結合的觸控面板400，使用者辨識非顯示區N1及N3的寬度W8為圍繞顯示區D左右側的邊界。Since the non-display areas N1 and N3 and the wiring areas T1 and T3 of the touch panel 140 are folded in the -z direction, and opposite to the z direction of the display display area D, when the user sees the flexible display from the front of the display area (z direction) In the touch panel 400 in which the panel is combined, the user recognizes that the width W 8 of the non-display areas N1 and N3 is a boundary around the left and right sides of the display area D.

如上所述，由於非顯示區N1及N3摺疊的寬度W8變得遠小於非顯示區N1及N3摺疊之前的原先寬度W0，使用者辨識形成自非顯示區N1及N3的顯示區D的邊界為顯著地減少。As described above, since the width W 8 of the non-display areas N1 and N3 is much smaller than the original width W 0 before the non-display areas N1 and N3 are folded, the user recognizes the display area D formed from the non-display areas N1 and N3. The boundaries are significantly reduced.

即使顯示於第1圖的可撓性顯示面板100-B包含於上述附圖中所示的可撓性顯示面板結合的觸控面板400，本發明不限於此，以及如第1圖、第12圖及第17圖顯示各種類的可撓性顯示面板可應用於現有實施例。Even if the flexible display panel 100-B shown in FIG. 1 includes the touch panel 400 in which the flexible display panel is combined as shown in the above drawings, the present invention is not limited thereto, and as shown in FIG. 1 and FIG. The figure and Fig. 17 show that various types of flexible display panels can be applied to the prior embodiments.

第25圖至第27圖顯示可撓性顯示面板結合各種支撐單元之例示性。為便於說明，以可撓性顯示面板100作為例子。然而，本發明不受限於此且可應用於顯示於第21圖的可撓性顯示面板結合的觸控面板400。Figures 25 through 27 show an illustration of a flexible display panel incorporating various support units. For convenience of explanation, the flexible display panel 100 is taken as an example. However, the present invention is not limited thereto and can be applied to the touch panel 400 of the flexible display panel shown in FIG. 21.

參照第25圖，在摺疊的非顯示區上的可撓性顯示面板100經由透明保護窗150所保護且支撐。Referring to Fig. 25, the flexible display panel 100 on the folded non-display area is protected and supported via the transparent protective window 150.

透明保護窗150可接上可撓性顯示面板100以對應可撓性顯示面板100的形狀，如對應可撓性顯示面板100的上表面，顯示影像及可撓性顯示面板摺疊的形狀。亦即，透明保護窗150可結合可撓性顯示面板100以對應顯示區D及可撓性顯示面板100的摺疊的非顯示區的形狀。透明保護窗150可具穿透性可准許光穿透可撓性顯示面板100的顯示螢幕，且具有避免因可撓性顯示面板200的恢復力變形的強度。因此，透明保護窗150可保護可撓性顯示面板100受外部衝擊或刮痕且可扮演圍繞可撓性顯示面板100形狀的支撐單元。即使未顯示，黏著劑可注射於可撓性顯示面板100與透明保護窗150之間。The transparent protection window 150 can be connected to the flexible display panel 100 to correspond to the shape of the flexible display panel 100, such as the upper surface of the flexible display panel 100, and the display image and the shape of the flexible display panel folded. That is, the transparent protection window 150 may be combined with the flexible display panel 100 to correspond to the shape of the display area D and the folded non-display area of the flexible display panel 100. The transparent protective window 150 may be transmissive to permit light to penetrate the display screen of the flexible display panel 100 and to have strength that avoids deformation due to the restoring force of the flexible display panel 200. Therefore, the transparent protective window 150 can protect the flexible display panel 100 from external impact or scratches and can act as a supporting unit around the shape of the flexible display panel 100. The adhesive can be injected between the flexible display panel 100 and the transparent protective window 150 even if not shown.

第25圖顯示透明保護窗150直接設置於可撓性顯示面板100上的例子。然而，本發明不限於此且也可應用於顯示於第21圖的可撓性顯示面板結合的觸控面板400。在這方面，透明保護窗150可與可撓性顯示面板100結合以對應可撓性顯示面板100及（或）可撓性顯示面板100的摺疊形狀。Fig. 25 shows an example in which the transparent protective window 150 is directly disposed on the flexible display panel 100. However, the present invention is not limited thereto and is also applicable to the touch panel 400 of the flexible display panel shown in FIG. 21. In this regard, the transparent protective window 150 may be combined with the flexible display panel 100 to correspond to the folded shape of the flexible display panel 100 and/or the flexible display panel 100.

參照第26圖，非顯示區摺疊的可撓性顯示面板100的內側經由支撐構件所支撐。支撐構件具有避免因可撓性顯示面板100的恢復力變型的強度。即使未顯示，黏著劑可更注射於可撓性顯示面板100與支撐構件之間。Referring to Fig. 26, the inner side of the flexible display panel 100 in which the non-display area is folded is supported via the support member. The support member has a strength that avoids deformation due to the restoring force of the flexible display panel 100. Even if not shown, the adhesive can be more injected between the flexible display panel 100 and the support member.

參照第27圖，非顯示區摺疊的可撓性顯示面板100經由平面（未彎曲）的透明保護窗170所支撐。可撓性顯示面板100的摺疊部分可經由支撐可撓性顯示面板100兩側的圈或框180所支撐。明顯地，即使未顯示，黏著劑可更注射於可撓性顯示面板100、透明保護窗170以及圈或框180之間。Referring to Fig. 27, the flexible display panel 100 folded in the non-display area is supported via a flat (unbent) transparent protective window 170. The folded portion of the flexible display panel 100 can be supported via a ring or frame 180 that supports both sides of the flexible display panel 100. Obviously, the adhesive may be injected more between the flexible display panel 100, the transparent protective window 170, and the ring or frame 180, even if not shown.

上述的支撐單元為支撐可撓性顯示面板的形狀，包含摺疊的顯示區及所屬技術領域具通常知識者的各種可能應用。The support unit described above is in the shape of supporting a flexible display panel, including a folded display area and various possible applications of those of ordinary skill in the art.

如上所述，可撓性顯示面板，其具有經由各種支撐單元之稱的摺疊形狀，可結合各種顯示裝置，如電視、電腦螢幕、個人顯示裝置、智慧型手機及其他類似物。使用者辨識可撓性顯示面板中顯示區與非顯示區的比例顯著地降低以提供相較於其他顯示裝置放大的影像螢幕。As described above, the flexible display panel has a folded shape called a variety of supporting units, and can be combined with various display devices such as a television, a computer screen, a personal display device, a smart phone, and the like. The user recognizes that the ratio of the display area to the non-display area in the flexible display panel is significantly reduced to provide an image screen that is magnified compared to other display devices.

根據上述實施例，顯示裝置提供以下影響。According to the above embodiment, the display device provides the following effects.

第一，非顯示區彎曲的方向相反於顯示顯示區的方向，以至於使用者辨識形成自非顯示區的顯示區的邊界顯著地減少。第二，保護薄膜位於可撓性顯示面板的上及下部分，以便覆蓋所有金屬層形成的區域，以至於當非顯示區彎曲時因彎曲壓力所造成配線的裂縫可避免。First, the direction in which the non-display area is curved is opposite to the direction in which the display area is displayed, so that the user recognizes that the boundary of the display area formed from the non-display area is significantly reduced. Second, the protective film is located on the upper and lower portions of the flexible display panel so as to cover the area where all the metal layers are formed, so that the crack of the wiring due to the bending pressure when the non-display area is bent can be avoided.

雖然本發明已被特別顯示且並參照較佳的實施例描述，其將由所屬技術領域的技術人員了解，在不脫離由所附申請專利範圍所限定之本發明的精神和範圍下，可以在其中進行在形式和細節上的各種改變。實施例應被認為是描述性的意義而非為了限制的目的。因此，本發明的範圍非藉由本發明的詳細敘述，而是藉由所附的申請專利範圍所定義，以及範圍內的所有差異將被解釋為包含在本發明中。Although the present invention has been particularly shown and described with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that the invention may be practiced without departing from the spirit and scope of the invention as defined by the appended claims.
