FIG. 1B is an enlarged schematic diagram of the area 1B of the display device 100A in FIG. 1A. Fig. 1C is a schematic cross-sectional view taken along the line 1C'-1C in Fig. 1A.

本實施方式所繪的顯示裝置100A係以攜帶式電子裝置為例，像是智慧型手機。如此的攜帶式電子裝置除可透過顯示區提供顯示功能之外，尚可透過配置鏡頭來實現擷取圖像或影像功能，且所配置的鏡頭會對應地被顯示區圍繞。然而，本揭露內容不以攜帶式電子裝置的類型為限，於其他實施方式中，顯示裝置也可以是其他種可透過配置鏡頭來實現擷取圖像或影像功能之電子裝置，像是筆記型電腦。 The display device 100A depicted in this embodiment takes a portable electronic device as an example, such as a smart phone. Such a portable electronic device can not only provide the display function through the display area, but also realize the function of capturing images or images by configuring the lens, and the configured lens is correspondingly surrounded by the display area. However, the content of the present disclosure is not limited to the type of portable electronic device.

顯示裝置100A包含鏡頭110、背光模組120、顯示面板130、膠體層140以及蓋板150，為了不使第1B圖過於複雜，第1B圖省略繪示了膠體層140。鏡頭110及背光模組120設置在顯示面板130的同一側，而膠體層140及蓋板150則是共同設置在顯示面板130的另一側。換言之，顯示面板130係設置在鏡頭110及背光模組120之上，而膠體層140及蓋板150則是共同設置在顯示面板130之上。 The display device 100A includes a lens 110, a backlight module 120, a display panel 130, a gel layer 140, and a cover 150. In order not to make Figure 1B too complicated, the gel layer 140 is omitted in Figure 1B. The lens 110 and the backlight module 120 are arranged on the same side of the display panel 130, and the glue layer 140 and the cover 150 are jointly arranged on the other side of the display panel 130. In other words, the display panel 130 is disposed on the lens 110 and the backlight module 120, and the gel layer 140 and the cover 150 are jointly disposed on the display panel 130.

顯示面板130包含第一偏光片131、陣列基板132、彩色濾光層基板134、遮光層136以及第二偏光片138，其中陣列基板132、彩色濾光層基板134及遮光層136設置在第一偏光片131與第二偏光片138之間。 The display panel 130 includes a first polarizer 131, an array substrate 132, a color filter substrate 134, a light-shielding layer 136, and a second polarizer 138. The array substrate 132, the color filter substrate 134 and the light-shielding layer 136 are disposed on the Between a polarizer 131 and a second polarizer 138.

陣列基板132可包含薄膜電晶體陣列(第1B圖未繪示)，且薄膜電晶體陣列中的每一個薄膜電晶體各自係可電性連接至不同的畫素電極(第1B圖未繪示)，從而形成多個畫素。陣列基板132更包含了掃描線及資料線(第1B圖未繪示)，這些掃描線及資料線可用來定址薄膜電晶體陣列中的每一個薄膜電晶體，以控制畫素電極的電位狀態(切換為高電位或是低電位)。 The array substrate 132 may include a thin film transistor array (not shown in Figure 1B), and each thin film transistor in the thin film transistor array can be electrically connected to a different pixel electrode (not shown in Figure 1B) , Thus forming multiple pixels. The array substrate 132 further includes scan lines and data lines (not shown in Figure 1B). These scan lines and data lines can be used to address each thin film transistor in the thin film transistor array to control the potential state of the pixel electrode ( Switch to high or low potential).

彩色濾光層基板134設置在陣列基板132之上，並可包含不同顏色的色阻層(第1B圖未繪示)，例如紅色色阻層、綠色色阻層及藍色色阻層，以使光束在通過彩色濾光層基板134後，可帶有相因應的顏色，從而使顯示面板130能提供影像。 The color filter substrate 134 is disposed on the array substrate 132, and may include color resist layers of different colors (not shown in Figure 1B), such as a red color resist layer, a green color resist layer, and a blue color resist layer, so that After the light beam passes through the color filter substrate 134, it may have a corresponding color, so that the display panel 130 can provide an image.

遮光層136設置在彩色濾光層基板134內，並可用來區分出顯示面板130的顯示區A1以及開口區A2。對於顯示面板130所具有的顯示區A1以及開口區A2來說，顯示區A1指的是可透過配置畫素並用來提供顯示畫面之區域，例如在第1A圖的顯示區A1中繪示有時間圖案及功能圖案，而開口區A2則是未配置有畫素且非用來提供顯示畫面之區域。亦即，顯示面板130所具有的顯示區A1以及開口區A2的定義方式是依據有無配置畫素及相因應之走線來區分。 The light shielding layer 136 is disposed in the color filter layer substrate 134 and can be used to distinguish the display area A1 and the opening area A2 of the display panel 130. For the display area A1 and the opening area A2 of the display panel 130, the display area A1 refers to the area where pixels can be arranged and used to provide a display screen. For example, the time is shown in the display area A1 in Figure 1A. Patterns and functional patterns, and the opening area A2 is an area that is not configured with pixels and is not used to provide a display screen. That is, the display area A1 and the opening area A2 of the display panel 130 are defined according to the presence or absence of the pixels and the corresponding wiring.

舉例來說，請看到第1C圖及第1D圖，第1D圖繪示顯示面板130透過遮光層136區分出顯示區A1及開口區A2的示意圖，且第1D圖的視角為垂直看向顯示面板130。第1D 圖中，開口區A2內未配置畫素，且自顯示區A1沿著縱向及橫向延伸的資料線139A及掃描線139B在經過開口區A2及其周圍時，會以繞過開口區A2的方式來排列，即這些繞過開口區A2的資料線139A及掃描線139B的延伸路徑會變為曲線或弧線。此外，由於顯示區A1內會有配置畫素及用來達成電性連接的走線，而開口區A2內未配置有畫素，故開口區A2的光穿透率可大於顯示區A1的光穿透率。 For example, please see Fig. 1C and Fig. 1D. Fig. 1D shows a schematic diagram of the display panel 130 separating the display area A1 and the opening area A2 through the light shielding layer 136, and the viewing angle of Fig. 1D is a vertical view. Panel 130. 1D In the figure, no pixels are arranged in the opening area A2, and the data lines 139A and scan lines 139B extending longitudinally and laterally from the display area A1 will bypass the opening area A2 when passing through the opening area A2 and its surroundings. The extension paths of the data lines 139A and the scan lines 139B that bypass the opening area A2 will become curved or arced. In addition, since the display area A1 has pixels and traces for electrical connection, and no pixels are arranged in the opening area A2, the light transmittance of the opening area A2 can be greater than that of the display area A1. Penetration rate.

遮光層136的設置位置可對應這些繞過開口區A2的資料線139A及掃描線139B，以提供遮蔽效果。進一步來說，遮光層136會是環狀的，並具有內邊界136I及外邊界136O。顯示面板130在對應遮光層136的外邊界136O之外的區域則為顯示區A1，且遮光層136之外邊界136O會鄰接顯示區A1之範圍邊界。顯示面板130在對應遮光層136的內邊界136I之內的區域為開口區A2，且遮光層136之內邊界136I會鄰接開口區A2之範圍邊界。換言之，遮光層136可視為是位在顯示區A1與開口區A2之間，並且遮光層136圍繞開口區A2。 The position of the light shielding layer 136 can correspond to the data lines 139A and the scan lines 139B bypassing the opening area A2 to provide a shielding effect. Furthermore, the light-shielding layer 136 is ring-shaped and has an inner boundary 136I and an outer boundary 136O. The area of the display panel 130 outside the outer boundary 136O of the corresponding light-shielding layer 136 is the display area A1, and the outer boundary 136O of the light-shielding layer 136 is adjacent to the range boundary of the display area A1. The area of the display panel 130 within the inner boundary 136I corresponding to the light-shielding layer 136 is the opening area A2, and the inner boundary 136I of the light-shielding layer 136 is adjacent to the range boundary of the opening area A2. In other words, the light shielding layer 136 can be regarded as being located between the display area A1 and the opening area A2, and the light shielding layer 136 surrounds the opening area A2.

請再回到第1A圖、第1B圖以及第1C圖。於陣列基板132及彩色濾光層基板134各自可包含透光基板(未示)，使得在陣列基板132及彩色濾光層基板134各自的製作過程中，其各自的層體或元件可以是形成在透光基板(未示)上，其中透光基板(未示)例如可以是玻璃基板。由於顯示面板130的顯示區A1及開口區A2的定義方式是依據有無配置畫素及相因應之走線來區分，故顯示面板130可透過多種配置來實現此開口區A2。 Please go back to Figure 1A, Figure 1B, and Figure 1C. Each of the array substrate 132 and the color filter layer substrate 134 may include a light-transmitting substrate (not shown), so that in the respective manufacturing processes of the array substrate 132 and the color filter layer substrate 134, their respective layers or elements can be formed On the transparent substrate (not shown), the transparent substrate (not shown) may be, for example, a glass substrate. Since the display area A1 and the opening area A2 of the display panel 130 are defined according to the presence or absence of pixels and corresponding traces, the display panel 130 can realize the opening area A2 through various configurations.

舉例來說，陣列基板132及彩色濾光層基板134各自的透光基板(未示)於對應開口區A2之處可以是被裁切掉而留下孔洞，或者，陣列基板132及彩色濾光層基板134各自的透光基板(未示)於對應開口區A2之處也可以是不被裁切掉。 For example, the light-transmitting substrates (not shown) of the array substrate 132 and the color filter layer substrate 134 may be cut out to leave holes at the corresponding opening area A2, or the array substrate 132 and the color filter The light-transmitting substrate (not shown) of each layer substrate 134 corresponding to the opening area A2 may not be cut off.

以第1C圖所繪為例，陣列基板132及彩色濾光層基板134各自的透光基板(未示)於對應開口區A2之處(以透光基板之一部分132S、134S表示)係未被裁切掉，使得透光基板(未示)之一部分132S、134S與開口區A2會至少部分重疊。對於對應開口區A2之處且未被裁切掉的透光基板(未示)之一部分132S、134S來說，其可因未配置有畫素，而因此具有的光穿透率會大於顯示面板130於對應顯示區A1之處的光穿透率。 Taking the drawing in Figure 1C as an example, the light-transmitting substrates (not shown) of the array substrate 132 and the color filter substrate 134 are located in the corresponding opening area A2 (indicated by the parts 132S and 134S of the light-transmitting substrate). Cut off so that a part of the transparent substrate (not shown) 132S, 134S and the opening area A2 will at least partially overlap. For a part of the transparent substrate (not shown) 132S, 134S that corresponds to the opening area A2 and is not cut off, it may not be provided with pixels, and therefore has a higher light transmittance than the display panel 130 corresponds to the light transmittance of the display area A1.

第一偏光片131可連接陣列基板132，其中第一偏光片131具有第一開口O1，且第一開口O1會位在開口區A2內。第二偏光片138可連接彩色濾光層基板134，且第二偏光片138會位在遮光層136之上，即第二偏光片138於彩色濾光層基板134之垂直投影會與遮光層136至少部分重疊。第二偏光片138具有第二開口O2，且第二開口O2也會位在開口區A2內。也就是說第一偏光片131的第一開口O1以及第二偏光片138的第二開口O2皆會與開口區A2重疊。 The first polarizer 131 can be connected to the array substrate 132, wherein the first polarizer 131 has a first opening O1, and the first opening O1 is located in the opening area A2. The second polarizer 138 can be connected to the color filter substrate 134, and the second polarizer 138 will be located on the light shielding layer 136, that is, the vertical projection of the second polarizer 138 on the color filter substrate 134 will be the same as the light shielding layer 136. At least partially overlap. The second polarizer 138 has a second opening O2, and the second opening O2 is also located in the opening area A2. That is to say, the first opening O1 of the first polarizer 131 and the second opening O2 of the second polarizer 138 will overlap the opening area A2.

設置於顯示面板130之下的鏡頭110會對準顯示面板130的開口區A2，具體來說，鏡頭110是對準陣列基板132及彩色濾光層基板134之與開口區A2重疊的部分，即其各自的透光基板之一部分132S、134S。開口區A2可做為鏡頭110進行擷取目標圖像或目標影像時的窗口。於部分實施方式中，遮光層136之內邊界136I係形成為圓形輪廓，且圓形輪廓的直徑136D介於2毫米至4毫米。換言之，提供給鏡頭110的窗口也會是具有圓形輪廓，且直徑為介於2毫米至4毫米。鏡頭110於顯示面板130之垂直投影係可由顯示區A1圍繞，使得在顯示裝置100A的上視視角中，可見到提供給鏡頭110的窗口會是被顯示面板130的顯示區A1圍繞著，此可如第1A圖所示。 The lens 110 disposed under the display panel 130 is aligned with the opening area A2 of the display panel 130. Specifically, the lens 110 is aligned with the portion of the array substrate 132 and the color filter substrate 134 that overlaps the opening area A2, namely Part of the respective light-transmitting substrates 132S, 134S. Opening area A2 can be used as lens 110 The window used to capture the target image or target image. In some embodiments, the inner boundary 136I of the light shielding layer 136 is formed as a circular contour, and the diameter 136D of the circular contour is between 2 mm and 4 mm. In other words, the window provided to the lens 110 will also have a circular outline and a diameter between 2 mm and 4 mm. The vertical projection system of the lens 110 on the display panel 130 can be surrounded by the display area A1, so that in the top viewing angle of the display device 100A, it can be seen that the window provided to the lens 110 is surrounded by the display area A1 of the display panel 130. As shown in Figure 1A.

此外，由於鏡頭110對準了顯示面板130的開口區A2，故鏡頭110可免於受到第一偏光片131及第二偏光片138遮蔽。換言之，在鏡頭110進行擷取目標圖像或目標影像時，此目標圖像或目標影像可因路徑是穿過第一偏光片131的第一開口O1以及第二偏光片138的第二開口O2，而使得目標圖像或目標影像不會受到偏光效果影響。 In addition, since the lens 110 is aligned with the opening area A2 of the display panel 130, the lens 110 can be prevented from being shielded by the first polarizer 131 and the second polarizer 138. In other words, when the lens 110 is capturing a target image or a target image, the target image or target image may pass through the first opening O1 of the first polarizer 131 and the second opening O2 of the second polarizer 138 because the path is , So that the target image or target image will not be affected by the polarization effect.

設置於顯示面板130之下的背光模組120可朝顯示面板130的顯示區A1提供光照。背光模組120可包含框架122以及光源模組124，其中框架122可透過墊片126連接至第一偏光片131。框架122可具有第三開口O3，且第一偏光片131的第一開口O1與框架122的第三開口O3可相連通。鏡頭110可位在第三開口O3內，以與背光模組120共同整合在顯示面板130的同一側。光源模組124可位在框架122與第一偏光片131之間，其中光源模組124可包含光源以及導光板(未繪示)，且光源可透過導光板提供均勻的正向光照予顯示面板130。 The backlight module 120 disposed under the display panel 130 can provide light to the display area A1 of the display panel 130. The backlight module 120 may include a frame 122 and a light source module 124, wherein the frame 122 may be connected to the first polarizer 131 through a spacer 126. The frame 122 may have a third opening O3, and the first opening O1 of the first polarizer 131 and the third opening O3 of the frame 122 may be communicated. The lens 110 can be located in the third opening O3 to be integrated with the backlight module 120 on the same side of the display panel 130 together. The light source module 124 can be located between the frame 122 and the first polarizer 131, wherein the light source module 124 can include a light source and a light guide plate (not shown), and the light source can pass through the light guide plate to provide uniform forward light to the display panel 130.

設置於顯示面板130之上的蓋板150可透過膠體層140固定，其中膠體層140可具有透光性，例如膠體層140 可以是光學膠。具體來說，膠體層140可覆蓋第二偏光片138，並填入至第二偏光片138的第二開口O2，以使蓋板150對顯示面板130有足夠的連接強度。 The cover 150 disposed on the display panel 130 can be fixed through the gel layer 140, wherein the gel layer 140 can have light permeability, for example, the gel layer 140 It can be optical glue. Specifically, the colloid layer 140 can cover the second polarizer 138 and fill the second opening O2 of the second polarizer 138 so that the cover 150 has sufficient connection strength to the display panel 130.

蓋板150具有透光性，其材料可包含有機物、玻璃或其組合，例如蓋板150可以是樹脂、壓克力或強化玻璃。蓋板150除了可用來保護顯示面板130，像是提供防塵、抗刮及抗水氣效果之外，尚可增進觀看者對顯示面板130的觀看體驗。以下敘述將對此關於「增進觀看者對顯示面板130的觀看體驗」之機制做進一步說明。 The cover plate 150 is light-transmissive, and its material may include organic matter, glass, or a combination thereof. For example, the cover plate 150 may be resin, acrylic or strengthened glass. In addition to protecting the display panel 130, the cover 150 can provide dust-proof, scratch-resistant and moisture-resistant effects, and can also enhance the viewer's viewing experience of the display panel 130. The following description will further explain the mechanism of “enhancing the viewer's viewing experience of the display panel 130”.

蓋板150可具有第一區域R1及第二區域R2，其中第一區域R1係可與顯示面板130的顯示區A1對應，而第二區域R2係可與顯示面板130的開口區A2對應。具體來說，第一區域R1於顯示面板130之垂直投影會與顯示區A1至少部分重疊，而第二區域R2於顯示面板130之垂直投影則會與開口區A2至少部分重疊。 The cover 150 may have a first area R1 and a second area R2. The first area R1 may correspond to the display area A1 of the display panel 130, and the second area R2 may correspond to the opening area A2 of the display panel 130. Specifically, the vertical projection of the first region R1 on the display panel 130 will at least partially overlap the display region A1, and the vertical projection of the second region R2 on the display panel 130 will at least partially overlap the opening region A2.

蓋板150在不同區域的厚度可以是有變化的。舉例來說，蓋板150於第一區域R1會具有第一厚度T1並於第二區域R2會具有第二厚度T2，其中第一厚度T1大於第二厚度T2。此外，蓋板150之厚度自第一區域R1至第二區域R2係為漸薄的。具體來說，蓋板150可更具有第三區域R3，第三區域R3位在第一區域R1與第二區域R2之間，且蓋板150於第三區域R3會具有第三厚度T3，其中第三厚度T3沿著自第一區域R1指向第二區域R2的方向會是漸薄的。 The thickness of the cover plate 150 in different regions may vary. For example, the cover 150 will have a first thickness T1 in the first region R1 and a second thickness T2 in the second region R2, wherein the first thickness T1 is greater than the second thickness T2. In addition, the thickness of the cover plate 150 is gradually thinner from the first region R1 to the second region R2. Specifically, the cover plate 150 may further have a third area R3, the third area R3 is located between the first area R1 and the second area R2, and the cover plate 150 has a third thickness T3 in the third area R3, wherein The third thickness T3 is gradually thinner along the direction from the first region R1 to the second region R2.

透過此配置，蓋板150於第三區域R3可形成為斜面152，且此斜面152係位在遮光層136之上，即斜面152於顯示面板130之垂直投影會與遮光層136至少部分重疊。具體來說，對於蓋板150於第三區域R3所形成的斜面152而言，其起始端位置會是對應第一區域R1與第三區域R3形成的交界線位置，且第一區域R1與第三區域R3所形成的交界線於顯示面板130之垂直投影係與遮光層136之外邊界136O切齊。斜面152的終點端位置則會是對應第二區域R2與第三區域R3形成的交界線位置，且第二區域R2與第三區域R3所形成的交界線於顯示面板130之垂直投影係位在遮光層136之內邊界136I與外邊界136O之間，並且也位在第二偏光片138內。 Through this configuration, the cover plate 150 can be formed in an oblique shape in the third area R3. The inclined surface 152 is located on the light shielding layer 136, that is, the vertical projection of the inclined surface 152 on the display panel 130 will at least partially overlap the light shielding layer 136. Specifically, for the inclined surface 152 formed by the cover plate 150 in the third region R3, the starting end position will correspond to the position of the boundary line formed by the first region R1 and the third region R3, and the first region R1 and the third region R3 The vertical projection of the boundary line formed by the three regions R3 on the display panel 130 is aligned with the outer boundary 136O of the light shielding layer 136. The end position of the inclined surface 152 corresponds to the position of the boundary line formed by the second region R2 and the third region R3, and the vertical projection of the boundary line formed by the second region R2 and the third region R3 on the display panel 130 is located at The light shielding layer 136 is located between the inner boundary 136I and the outer boundary 136O, and is also located in the second polarizer 138.

透過由蓋板150於第三區域R3所形成的斜面152，可將自顯示面板130的顯示區A1提供之光束於穿過斜面152後發生偏折，從而增進提供給觀看者的視覺感受。 Through the inclined surface 152 formed by the cover 150 in the third region R3, the light beam provided from the display area A1 of the display panel 130 can be deflected after passing through the inclined surface 152, thereby enhancing the visual experience provided to the viewer.

請再看到第1E圖，第1E圖繪示顯示面板130的顯示區A1所提供之光束102的光路示意圖。顯示面板130的顯示區A1所提供之光束102可視作顯示面板130的顯示區A1所提供的影像，其中第1E圖的區塊EA為表示光束102的光路，而第1E圖的區塊EB則是表示光束102提供給觀看者的等效視覺感受。 Please see FIG. 1E again. FIG. 1E is a schematic diagram of the light path of the light beam 102 provided by the display area A1 of the display panel 130. The light beam 102 provided by the display area A1 of the display panel 130 can be regarded as the image provided by the display area A1 of the display panel 130. The block EA in Figure 1E represents the light path of the beam 102, and the block EB in Figure 1E It represents the equivalent visual experience provided by the light beam 102 to the viewer.

自顯示面板130的顯示區A1提供之光束102的照射範圍可以是自邊界102A至邊界102B。當光束102行進至蓋板150於第三區域R3所形成的斜面152時，光束102會因折射率差異而產生偏折。舉例來說，當顯示裝置是放置在大氣環境下的時候，蓋板150的表面可與空氣形成交界面，像是蓋板150 於第三區域R3所形成的斜面152會與空氣形成交界面。由於空氣可視為一種光傳輸介質，且蓋板150的折射率會異於空氣，故穿過此交界面的光束102會因折射而產生偏折。由於光束102發生偏折的位置是在遮光層136的正上方，且光束102於偏折後會朝著遠離遮光層136的方向行進，故位在遮光層136正上方的部分範圍(標記為範圍104表示)可以感受到光束102致使的光照補償，從而降低遮光層136在視覺效果上的寬度。 The irradiation range of the light beam 102 provided from the display area A1 of the display panel 130 may be from the boundary 102A to the boundary 102B. When the light beam 102 travels to the inclined plane 152 formed by the cover 150 in the third region R3, the light beam 102 will be deflected due to the difference in refractive index. For example, when the display device is placed in an atmospheric environment, the surface of the cover 150 can form an interface with the air, such as the cover 150 The inclined surface 152 formed in the third region R3 forms an interface with air. Since air can be regarded as a light transmission medium, and the refractive index of the cover 150 is different from that of air, the light beam 102 passing through the interface will be deflected due to refraction. Since the position where the beam 102 is deflected is directly above the light-shielding layer 136, and the beam 102 will travel away from the light-shielding layer 136 after being deflected, it is located in the part of the range directly above the light-shielding layer 136 (marked as range 104) The illumination compensation caused by the light beam 102 can be felt, thereby reducing the width of the light shielding layer 136 in terms of visual effects.

具體來說，第1E圖的區塊EA中的遮光層136會具有寬度L1，此寬度L1例如是遮光層136的內徑與外徑的差值，而遮光層136正上方之提供光照補償的範圍104則會具有寬度L2。因此，遮光層136在觀看者於視覺效果上的寬度會變成是寬度L1減掉寬度L2。由於遮光層136正上方的範圍104可補償光照，故觀看者會將此範圍104辨認為顯示區A1，使得觀看者在視覺上認定的顯示區範圍會大於實際顯示區A1範圍，並可降低遮光層136的存在感，從而增進觀看者對顯示面板130的觀看體驗。 Specifically, the light-shielding layer 136 in the block EA of FIG. 1E will have a width L1. The width L1 is, for example, the difference between the inner diameter and the outer diameter of the light-shielding layer 136, and the light-shielding layer 136 directly above provides illumination compensation. The range 104 will have a width L2. Therefore, the width of the light shielding layer 136 in terms of the viewer's visual effect becomes the width L1 minus the width L2. Since the area 104 directly above the light-shielding layer 136 can compensate for light, the viewer will recognize this area 104 as the display area A1, so that the viewer visually recognizes that the display area is larger than the actual display area A1, and the shading can be reduced The presence of the layer 136 enhances the viewer's viewing experience of the display panel 130.

上述「降低遮光層在視覺效果上的寬度」的降低程度可以由寬度L2與寬度L1的比值量化成數值，此數值亦可稱「補償率」，且此量化而成的數值係與顯示裝置的部分參數有相關性。為了方便說明，以下與光束102相關的參數敘述是以照射範圍內的光線106做為範例來說明。 The degree of reduction of the aforementioned "reducing the width of the light-shielding layer in terms of visual effects" can be quantified by the ratio of the width L2 to the width L1 as a numerical value. This numerical value can also be called the "compensation rate", and the quantified numerical value is related to the display device Some parameters are relevant. For the convenience of description, the following description of the parameters related to the light beam 102 takes the light 106 within the irradiation range as an example.

蓋板150可具有第一折射率n1，而蓋板150上方的光傳輸介質108(例如前述之空氣)可具有第二折射率n2，且第一折射率n1大於第二折射率n2。蓋板150之第一區域R1與膠體層140的厚度總和以距離d表示。對於由顯示面板130的顯示區A1所提供之朝蓋板150行進的光線106，其相對顯示面板130之視角為角度θ，且光線106於蓋板150之斜面152的入射角為角度θi而折射角為角度θt。蓋板150於第三區域R3所形成的斜面152相對蓋板150於第二區域R2的上表面的銳夾角為夾角α。 The cover 150 may have a first refractive index n1, and the light transmission medium 108 (such as the aforementioned air) above the cover 150 may have a second refractive index n2, and the first refractive index n1 is greater than the second refractive index n2. The total thickness of the first region R1 of the cover 150 and the gel layer 140 is represented by a distance d. For the light 106 traveling toward the cover 150 provided by the display area A1 of the display panel 130, its viewing angle with respect to the display panel 130 is an angle θ, and the incident angle of the light 106 on the inclined surface 152 of the cover 150 is an angle θi and is refracted The angle is the angle θt. The acute included angle between the inclined surface 152 formed by the cover plate 150 in the third region R3 and the upper surface of the cover plate 150 in the second region R2 is an included angle α .

透過幾何關係，可得知夾角α等於角度θt，且角度θi等於夾角α與角度θ的差值。再透過司乃耳定律(Snell’s Law)，即可推得夾角α實質上滿足方程式(I)，如下所示：

，並且利用距離d、寬度L1及寬度L2對應上述各角度在三角函數上的關係，可再推得寬度L2實質上滿足方程式(II)，如下所示：L2=[d*(sinα)-L1*(sinα)*(tanθi)](cosα).........(II) Through the geometric relationship, it can be known that the angle α is equal to the angle θt, and the angle θi is equal to the difference between the angle α and the angle θ. Then through Snell's Law, we can infer that the angle α substantially satisfies the equation (I), as shown below:

, And using the relationship between the distance d, the width L1 and the width L2 corresponding to the above-mentioned angles on the trigonometric function, it can be deduced that the width L2 substantially satisfies the equation (II), as follows: L2=[d*(sinα)-L1 *(sinα)*(tanθi)](cosα).........(II)

上述方程式(I)及(II)可用來做為調整補償率之依據。舉例來說，在部分參數為固定的情況下，可調整顯示面板之視角(角度θ)來調整補償率的比值。 The above equations (I) and (II) can be used as the basis for adjusting the compensation rate. For example, when some parameters are fixed, the viewing angle (angle θ) of the display panel can be adjusted to adjust the compensation rate ratio.

舉例來說，請看到第1F圖，第1F圖繪示顯示面板之視角與補償率的關係圖。第1F圖中，橫軸為面板視角，單位為度；縱軸為補償率(即前述提及之寬度L2與寬度L1的比值)，單位為百分比。第1F圖所繪的關係圖是在寬度L1定為430微米；距離d定為500微米；第一折射率n1定為1.5；以及第二折射率n2定為1之條件下繪製而成。 For example, please see Figure 1F. Figure 1F shows the relationship between the viewing angle of the display panel and the compensation rate. In Figure 1F, the horizontal axis is the viewing angle of the panel, and the unit is degree; the vertical axis is the compensation rate (that is, the ratio of the aforementioned width L2 to the width L1), and the unit is a percentage. The relationship diagram drawn in Figure 1F is drawn under the conditions that the width L1 is set to 430 microns; the distance d is set to 500 microns; the first refractive index n1 is set to 1.5; and the second refractive index n2 is set to 1.

如第1F圖的點P所示，當顯示面板提供朝蓋板行進之光束為呈現對應顯示面板之視角(角度θ)約12度時，可達到的補償率約是35%。此外，在此條件下的夾角α會是約34度，而寬度L2會是約278微米，即是將遮光層136在視覺效果上的寬度自430微米降低成278微米。 As shown at point P in Figure 1F, when the display panel provides a light beam traveling toward the cover to show a viewing angle (angle θ) corresponding to the display panel of about 12 degrees, the achievable compensation rate is about 35%. In addition, the included angle α under this condition will be about 34 degrees, and the width L2 will be about 278 microns, that is, the visual effect width of the light shielding layer 136 is reduced from 430 microns to 278 microns.

上述條件僅做為範例來方便說明，而非用限定本揭露內容。透過上述說明，可得知補償率是可以由調整上所述的各參數來調整。藉由調整各參數，可實現補償率之百分比為介於10%至100%。 The above conditions are only used as examples for the convenience of explanation, rather than limiting the content of this disclosure. From the above description, it can be known that the compensation rate can be adjusted by adjusting the parameters mentioned above. By adjusting each parameter, the percentage of compensation rate can be achieved between 10% and 100%.

請再回到第1B圖及第1C圖。在所蓋板150於第三區域R3所形成的斜面152是用來使光束偏折的情況下，將斜面152的起始端位置設計為不超過遮光層136之與外邊界136O之外，以及將斜面152的終點端位置設計為位在第二偏光片138內，可達到避免前述折射機制衍生出會降低觀看體驗的因素，例如，可避免顯示區A1在接近圍繞開口區A2的部分所提供之影像亮度差異太大，或者，可避免於斜面152發生折射的光束影響到鏡頭110對圖像或影像的擷取。 Please go back to Figure 1B and Figure 1C. In the case where the inclined plane 152 formed by the cover plate 150 in the third region R3 is used to deflect the light beam, the starting end position of the inclined plane 152 is designed to not exceed the outer boundary 136O of the light shielding layer 136, and The end position of the inclined surface 152 is designed to be located in the second polarizer 138, which can prevent the aforementioned refraction mechanism from deriving factors that would reduce the viewing experience. For example, it can prevent the display area A1 from being provided near the opening area A2. The image brightness difference is too large, or it can prevent the light beam refracted on the inclined surface 152 from affecting the image or image capture by the lens 110.

請再看到第2圖，第2圖為依據本揭露內容的第二實施方式繪示顯示裝置100B的剖面示意圖，其中剖面位置可雷同第1C圖。本實施方式與第一實施方式的至少一個差異點在於，本實施方式的陣列基板132及彩色濾光層基板134各自的透光基板具有相連接的孔洞132H及134H。具體來說，陣列基板132及彩色濾光層基板134各自的透光基板於對應開口區A2之處可被裁切掉，從而形成孔洞132H及134H，且孔洞132H 及134H與開口區A2至少部分重疊。膠體層140的塗佈位置可對應孔洞132H及134H的位置，例如膠體層140係未塗佈至覆蓋孔洞132H及134H。此外，鏡頭110可對準孔洞132H及134H，並將孔洞132H及134H視為擷取圖像或影像時的窗口。 Please see FIG. 2 again. FIG. 2 is a schematic cross-sectional view of the display device 100B according to the second embodiment of the present disclosure, and the cross-sectional position can be similar to that of FIG. 1C. At least one difference between this embodiment and the first embodiment is that the light-transmitting substrates of the array substrate 132 and the color filter substrate 134 of this embodiment have connected holes 132H and 134H. Specifically, the respective light-transmitting substrates of the array substrate 132 and the color filter substrate 134 can be cut off at the corresponding opening area A2, thereby forming holes 132H and 134H, and the holes 132H And 134H at least partially overlap the opening area A2. The coating position of the colloid layer 140 may correspond to the positions of the holes 132H and 134H, for example, the colloid layer 140 is not coated to cover the holes 132H and 134H. In addition, the lens 110 can be aligned with the holes 132H and 134H, and the holes 132H and 134H are regarded as windows for capturing images or images.

請再看到第3圖，第3圖為依據本揭露內容的第三實施方式繪示顯示裝置100C的剖面示意圖，其中剖面位置可雷同第1C圖。本實施方式與第一實施方式的至少一個差異點在於，本實施方式的顯示裝置100C更包含介電材料層160。介電材料層160設置在蓋板150上，並至少覆蓋蓋板150的第二區域R2及第三區域R3。 Please refer to FIG. 3 again. FIG. 3 is a schematic cross-sectional view of the display device 100C according to the third embodiment of the present disclosure, wherein the cross-sectional position can be the same as that of FIG. 1C. At least one difference between this embodiment and the first embodiment is that the display device 100C of this embodiment further includes a dielectric material layer 160. The dielectric material layer 160 is disposed on the cover plate 150 and covers at least the second area R2 and the third area R3 of the cover plate 150.

在前述關於方程式(I)及(II)的說明中，由於是將空氣當做蓋板150上方的光傳輸介質，故方程式(I)及(II)的計算結果會是與空氣的折射率有相關。本實施方式中，係將介電材料層160做為蓋板150上方的光傳輸介質，其中介電材料層160所提供的折射率會異於空氣折射率，具體來說，介電材料層160的折射率會大於空氣的折射率，並且小於蓋板150的折射率。透過介電材料層160的折射率，可調整方程式(I)及(II)的計算結果，從而對補償率的調整可更彈性。 In the foregoing description of equations (I) and (II), since air is used as the optical transmission medium above the cover 150, the calculation results of equations (I) and (II) will be related to the refractive index of air . In this embodiment, the dielectric material layer 160 is used as the optical transmission medium above the cover plate 150. The refractive index provided by the dielectric material layer 160 is different from the refractive index of air. Specifically, the dielectric material layer 160 The refractive index of is greater than the refractive index of air and smaller than the refractive index of the cover 150. Through the refractive index of the dielectric material layer 160, the calculation results of equations (I) and (II) can be adjusted, so that the adjustment of the compensation rate can be more flexible.

此外，介電材料層160可更進一步地覆蓋蓋板150的第一區域R1，使得介電材料層160為完全地佈滿在蓋板150上，且介電材料層160之第一上表面S1相對蓋板150於對應第一區域R1、第二區域R2及第三區域R3所共同形成之第二上表面S2為較平坦的。透過此配置，介電材料層160可使顯示裝置100C具有平坦的表面，以增進使用者對顯示裝置100C的使用體驗。另一方面，介電材料層160也可保護蓋板150之具有起伏的第二上表面S2(此起伏例如是因蓋板150於各區域之厚度不同所導致)，從而防止斜面152因撞擊而致使破損。 In addition, the dielectric material layer 160 can further cover the first region R1 of the cover plate 150, so that the dielectric material layer 160 is completely covered on the cover plate 150, and the first upper surface S1 of the dielectric material layer 160 The second upper surface S2 formed by the opposite cover 150 corresponding to the first region R1, the second region R2, and the third region R3 is relatively flat. Through this configuration, the dielectric material layer 160 can make the display device 100C have a flat surface, so as to enhance the user's use of the display device 100C Experience. On the other hand, the dielectric material layer 160 can also protect the undulating second upper surface S2 of the cover 150 (the undulations are caused by, for example, the thickness of the cover 150 in different regions), thereby preventing the inclined surface 152 from being impacted. Cause damage.

請再看到第4A圖及第4B圖。第4A圖為依據本揭露內容的第四實施方式繪示顯示裝置100D的部分區域的放大示意圖，其中第4A圖所繪的部分區域之範圍可與第1B圖雷同。第4B圖為依據本揭露內容的第四實施方式繪示顯示裝置100D的剖面示意圖，其中剖面位置可雷同第1C圖。本實施方式與第一實施方式的至少一個差異點在於，本實施方式的斜面152之起始端位置與遮光層136之外邊界136O的相對位置關係異於第一實施方式。具體來說，斜面152之起始端位置會是對應第一區域R1與第三區域R3形成的交界線位置，且本實施方式的第一區域R1與第三區域R3所形成的交界線於顯示面板130之垂直投影係會位在遮光層136之內邊界136I與外邊界136O之間。如此變更的配置可使顯示裝置100D在製作上更有彈性，從而提升製程可靠度。 Please see Figure 4A and Figure 4B again. FIG. 4A is an enlarged schematic diagram showing a partial area of the display device 100D according to the fourth embodiment of the present disclosure, wherein the range of the partial area depicted in FIG. 4A may be the same as that in FIG. 1B. FIG. 4B is a schematic cross-sectional view of the display device 100D according to the fourth embodiment of the present disclosure, wherein the position of the cross-section may be the same as that of FIG. 1C. At least one difference between this embodiment and the first embodiment is that the relative positional relationship between the starting end position of the inclined surface 152 and the outer boundary 136O of the light shielding layer 136 in this embodiment is different from that of the first embodiment. Specifically, the starting end position of the inclined surface 152 corresponds to the position of the boundary line formed by the first region R1 and the third region R3, and the boundary line formed by the first region R1 and the third region R3 in this embodiment is on the display panel The vertical projection of 130 will be located between the inner boundary 136I and the outer boundary 136O of the light shielding layer 136. Such a modified configuration can make the display device 100D more flexible in manufacturing, thereby improving the reliability of the manufacturing process.

雖本實施方式是以調整蓋板150的斜面152之起始端位置來做說明，然而，本揭露內容不以此為限，當顯示裝置100D有不同顯示需求時，亦可調整斜面152之終點端位置與其他層體的相對位置關係。舉例來說，斜面152之終點端位置會是對應第二區域R2與第三區域R3形成的交界線位置，雖本實施方式中的第二區域R2與第三區域R3所形成的交界線於顯示面板130之垂直投影是位在第二偏光片138內，然而，於其他實施方式中，此交界線亦可與第二偏光片138之邊界切齊。 Although this embodiment is described by adjusting the starting end position of the inclined surface 152 of the cover 150, the content of the disclosure is not limited to this. When the display device 100D has different display requirements, the end point of the inclined surface 152 can also be adjusted The relative position relationship between the position and other layers. For example, the end position of the inclined surface 152 corresponds to the position of the boundary line formed by the second region R2 and the third region R3, although the boundary line formed by the second region R2 and the third region R3 in this embodiment is shown The vertical projection of the panel 130 is located in the second polarizer 138. However, in other embodiments, the boundary line may also be cut to the boundary of the second polarizer 138 Qi.

綜上所述，本揭露內容的顯示裝置包含鏡頭、顯示面板以及蓋板。顯示面板設置在鏡頭與蓋板之間，並具有顯示區以及開口區。鏡頭可對準開口區，並且由顯示區圍繞。蓋板具有第一區域及第二區域，且第一區域及第二區域分別位在顯示面板的顯示區及開口區之上。蓋板之厚度自第一區域至第二區域係為漸薄的，從而在第一區域與第二區域之間形成斜面。自顯示面板的顯示區提供之光束可在穿過斜面後發生偏折，使得觀看者在視覺上認定的顯示區範圍會大於實際顯示區範圍，從而增進觀看者對顯示面板的觀看體驗。 In summary, the display device of the present disclosure includes a lens, a display panel, and a cover plate. The display panel is arranged between the lens and the cover plate, and has a display area and an opening area. The lens can be aimed at the opening area and surrounded by the display area. The cover plate has a first area and a second area, and the first area and the second area are respectively located on the display area and the opening area of the display panel. The thickness of the cover plate is gradually thinner from the first area to the second area, thereby forming a slope between the first area and the second area. The light beam provided from the display area of the display panel can be deflected after passing through the inclined plane, so that the range of the display area visually recognized by the viewer is larger than the actual display area, thereby enhancing the viewer's viewing experience of the display panel.
