請參照圖1所示，其為本發明較佳實施例之一種觸控顯示裝置1的示意圖。 Please refer to FIG. 1 , which is a schematic diagram of a touch display device 1 according to a preferred embodiment of the present invention.
觸控顯示裝置1包括一顯示面板11以及一觸控面板12。 The touch display device 1 includes a display panel 11 and a touch panel 12 .
顯示面板11具有一第一基板111、一第二基板112及一光學膜，第一基板111與第二基板112相對設置。其中，顯示面板11可為一液晶顯示面板(LCD)或一有機發光二極體顯示面板(OLED)。在本實施例中，顯示面板11係以一液晶顯示面板為例。其中，顯示面板11之第一基板111、第二基板112及觸控面板12的材質可包含玻璃，且玻璃的材質可為相同或不相同。另外，本實施例之第二基板112的面積係小於第一基板111的面積為例。 The display panel 11 has a first substrate 111, a second substrate 112, and an optical film. The first substrate 111 and the second substrate 112 are disposed opposite to each other. The display panel 11 can be a liquid crystal display panel (LCD) or an organic light emitting diode display panel (OLED). In the embodiment, the display panel 11 is exemplified by a liquid crystal display panel. The material of the first substrate 111, the second substrate 112, and the touch panel 12 of the display panel 11 may include glass, and the materials of the glass may be the same or different. In addition, the area of the second substrate 112 of the present embodiment is smaller than the area of the first substrate 111.
在本實施例中，第一基板111係為一薄膜電晶體基板，而第二基板112係為一彩色濾光基板為例，不過，在其它的實施態樣中，彩色濾光基板上的黑色矩陣層(black matrix)及濾光層也可分別設置於薄膜電晶體基板上，使得第一基板111成為一BOA(BM on array)基板，或成為一COA(color filter on array)基板。於此，均不加以限制。此外，顯示面板11更可具有一液晶層(圖未顯示)，液晶層係夾置於第一基板111與第二基板112之間。 In this embodiment, the first substrate 111 is a thin film transistor substrate, and the second substrate 112 is a color filter substrate. However, in other embodiments, the black color on the color filter substrate is used. The black matrix and the filter layer may also be respectively disposed on the thin film transistor substrate, so that the first substrate 111 becomes a BOA (BM on array) substrate or becomes a COA (color filter on array) substrate. There are no restrictions on this. In addition, the display panel 11 may further have a liquid crystal layer (not shown), and the liquid crystal layer is sandwiched between the first substrate 111 and the second substrate 112.
觸控面板12具有一觸控基板121，第二基板112位於觸控基板121與第一基板111之間。於此，觸控面板12之觸控基板121並不包含控制觸控面板12的控制IC。本實施例之顯示面板11係以具有二光學膜113、114為例。光學膜113為一下偏光板，而光學膜114為一上偏光板。其中，光學膜為113(下偏光板)設置於第一基板111遠離第二基板112之一側，光學膜114(上偏光板)設置於第二基板112與觸控面板12之間。於此，光學膜113位於第一基板111之下側表面，而光學膜114位於第二基板112之上側表面。不過，在其它的實施態樣中，若顯示面板11為一有機發光二極體顯示面板時，則光學膜的數量為一，並例如但不限於為1/4 λ的圓偏振片、偏光板或抗反射膜，或其組合，且位於第二基板112與觸控面板12之間。 The touch panel 12 has a touch substrate 121 , and the second substrate 112 is located between the touch substrate 121 and the first substrate 111 . The touch substrate 121 of the touch panel 12 does not include a control IC for controlling the touch panel 12 . The display panel 11 of the present embodiment is exemplified by having two optical films 113 and 114. The optical film 113 is a lower polarizing plate, and the optical film 114 is an upper polarizing plate. The optical film 113 (lower polarizing plate) is disposed on one side of the first substrate 111 away from the second substrate 112, and the optical film 114 (upper polarizing plate) is disposed between the second substrate 112 and the touch panel 12. Here, the optical film 113 is located on the lower side surface of the first substrate 111, and the optical film 114 is located on the upper side surface of the second substrate 112. However, in other embodiments, if the display panel 11 is an organic light emitting diode display panel, the number of optical films is one, and is, for example but not limited to, a 1/4 λ circular polarizing plate and a polarizing plate. Or an anti-reflection film, or a combination thereof, and located between the second substrate 112 and the touch panel 12.
其中，光學膜113的面積小於第一基板111的面積，而光 學膜114的面積小於第二基板112的面積。不過，在其它的實施態樣中，光學膜113的面積可等於第一基板111的面積，而光學膜114的面積也可等於第二基板112的面積。 Wherein, the area of the optical film 113 is smaller than the area of the first substrate 111, and the light The area of the film 114 is smaller than the area of the second substrate 112. However, in other embodiments, the area of the optical film 113 may be equal to the area of the first substrate 111, and the area of the optical film 114 may also be equal to the area of the second substrate 112.
觸控面板12(觸控基板121)與顯示面板11係相對而設，並可以膠合或其它連接機構方式設置於第二基板112之上。其中，觸控基板121可與光學膜114連接，並例如藉由一黏著件(圖未繪示)以直接連結(direct bonding)的方式將觸控面板12與顯示面板11結合。當然，觸控基板121與光學膜114也可沒有接觸，而是例如以口型連結(air bonding)的方式將觸控面板12與顯示面板11結合。以口型連結(即air bonding)而言，可於第二基板112之上表面的四個側邊設置一圈黏著件或只在部分側邊設置黏著件，也可以點膠方式設置黏著件，以將觸控基板121黏合於顯示面板11上。另外，本實施例之光學膜114的尺寸係小於第二基板112的尺寸，並設置於第二基板112與觸控基板121之間而受到黏著件的包圍，使得光學膜114與觸控基板121之間形成一空隙。此外，觸控基板121的面積係小於或等於第二基板112的面積。本實施例係以觸控基板121的面積小於第二基板112的面積為例。因此，在本實施例中，觸控基板121的面積小於第二基板112的面積，且第二基板112的面積小於第一基板111的面積。 The touch panel 12 (the touch substrate 121) is disposed opposite to the display panel 11 and can be disposed on the second substrate 112 by glue or other connection mechanism. The touch panel 121 can be connected to the optical film 114, and the touch panel 12 and the display panel 11 can be combined by direct bonding, for example, by an adhesive member (not shown). Of course, the touch substrate 121 and the optical film 114 may not be in contact with each other, and the touch panel 12 and the display panel 11 may be combined, for example, by air bonding. In the case of the air bonding, a ring of adhesives may be disposed on the four sides of the upper surface of the second substrate 112 or only on the side of the side, or the adhesive may be disposed in a dispensing manner. The touch substrate 121 is bonded to the display panel 11 . In addition, the size of the optical film 114 of the present embodiment is smaller than that of the second substrate 112, and is disposed between the second substrate 112 and the touch substrate 121 and surrounded by the adhesive member, so that the optical film 114 and the touch substrate 121 A gap is formed between them. In addition, the area of the touch substrate 121 is less than or equal to the area of the second substrate 112. In this embodiment, the area of the touch substrate 121 is smaller than the area of the second substrate 112. Therefore, in this embodiment, the area of the touch substrate 121 is smaller than the area of the second substrate 112, and the area of the second substrate 112 is smaller than the area of the first substrate 111.
另外，第一基板111具有一第一側邊S1，第二基板112具有對應第一側邊S1之一第二側邊S2，第一基板111之第一側邊S1係突出於第二基板112之第二側邊S2。此外，本發明並不特別界定第一基板111的其它側邊與第二基板112之對應側邊的相對關係，第一基板111的其它側邊可突出、或內縮、或對齊第二基板112之對應側邊。 In addition, the first substrate 111 has a first side S1, and the second substrate 112 has a second side S2 corresponding to the first side S1. The first side S1 of the first substrate 111 protrudes from the second substrate 112. The second side S2. In addition, the present invention does not particularly define the relative relationship between the other sides of the first substrate 111 and the corresponding sides of the second substrate 112. The other sides of the first substrate 111 may protrude, or retract, or align with the second substrate 112. Corresponding sides.
第一基板111之第一側邊S1係突出於第二基板112之第二側邊S2，且其突出長度A可介於0mm至10mm之間。另外，第一基板111之第一側邊S1係突出於光學膜114之對應側邊，且其突出長度B的最大值為10mm。此外，觸控基板121與光學膜114之間的距離C係可介於0~0.3mm。由於觸控基板121與光學膜114之間的間隙(距離C)極小，故可讓觸控基板121在觸壓過程中的變形量較現行技術來得小，且顯示面板11 也某種程度可承載觸控基板121，使得觸控面板12可不需再做進一步的強化處理。另外，也因電路連接板13與顯示面板11之光學膜114於垂直第二基板112之投影面上不重疊，但與第一基板111部分重疊，故可有效縮小觸控基板121與電路連接板13接合區域的尺寸，進而有效縮小觸控面板12的整體尺寸。 The first side S1 of the first substrate 111 protrudes from the second side S2 of the second substrate 112, and the protruding length A thereof may be between 0 mm and 10 mm. In addition, the first side S1 of the first substrate 111 protrudes from the corresponding side of the optical film 114, and the maximum length of the protruding length B is 10 mm. In addition, the distance C between the touch substrate 121 and the optical film 114 may be between 0 and 0.3 mm. Since the gap (distance C) between the touch substrate 121 and the optical film 114 is extremely small, the amount of deformation of the touch substrate 121 during the touch process can be made smaller than that of the prior art, and the display panel 11 The touch substrate 121 can also be carried to some extent, so that the touch panel 12 does not need to be further strengthened. In addition, since the circuit board 13 and the optical film 114 of the display panel 11 do not overlap on the projection surface of the second substrate 112, but partially overlap the first substrate 111, the touch substrate 121 and the circuit connection board can be effectively reduced. 13 the size of the bonding area, thereby effectively reducing the overall size of the touch panel 12.
另外，請參照圖2A及圖2B所示，其分別為本發明較佳實施例不同實施態樣之觸控顯示裝置1a、1b的示意圖。 2A and 2B are schematic diagrams of touch display devices 1a and 1b according to different embodiments of the preferred embodiment of the present invention.
如圖2A所示，與觸控顯示裝置1主要的不同在於，觸控顯示裝置1a更包括一電路連接板13，電路連接板13設置於觸控基板121，並與觸控基板121連結(bonding)而電性連接。於此，電路連接板13係與觸控基板121的下表面連結而電性連接，且於垂直第一基板111之投影面上，電路連接板13與第一基板111至少部分重疊。換言之，於觸控面板12的上方俯視時，電路連接板13的一部分係位於第一基板111之上。其中，電路連接板13與驅動觸控面板12之驅動電路電性連接，以藉由電路連接板13控制觸控面板12的作動。於此，電路連接板13例如但不限於為軟式印刷電路(Flexible Print Circuit,FPC)板或軟硬結合板。 As shown in FIG. 2A , the main difference between the touch display device 1 and the touch display device 1 is that the circuit board 13 is disposed on the touch substrate 121 and coupled to the touch substrate 121 . ) and electrically connected. Here, the circuit connection board 13 is electrically connected to the lower surface of the touch substrate 121, and the circuit connection board 13 and the first substrate 111 are at least partially overlapped on the projection surface of the vertical first substrate 111.
