Description
本發明是有關於一種顯示裝置,且特別是有關於一種具有無邊框顯示效果的顯示裝置。 The present invention relates to a display device, and more particularly to a display device having a frameless display effect.
近年來,為了螢幕尺寸的最大化,窄邊框的顯示面板越來越廣泛的應用於各種裝置上。為了實現大尺寸顯示裝置,拼接多片顯示面板的概念與應用也逐漸浮現。然而,多片顯示面板拼接成一個大型顯示裝置時,顯示面板的邊框寬度往往導致顯示畫面在相鄰顯示面板之間的交界處出現不連續性,如圖1所示。在圖1中,顯示裝置1包括彼此相接的第一顯示面板10與第二顯示面板20,其中第一顯示面板10所顯示的影像12與第二顯示面板20所顯示的影像22之間存在有明顯的間隙30,且間隙30實質上由第一顯示面板10與第二顯示面板20的邊框所造成的。為了縮減間隙30,第一顯示面板10與第二顯示面板20往往採用窄邊框的設計,但仍無法真正地達成理想的顯示畫面。 In recent years, in order to maximize the size of the screen, the display panel of the narrow bezel has been widely used in various devices. In order to realize a large-sized display device, the concept and application of splicing a plurality of display panels have gradually emerged. However, when a plurality of display panels are spliced into one large display device, the frame width of the display panel often causes discontinuity at the interface between adjacent display panels, as shown in FIG. In FIG. 1 , the display device 1 includes a first display panel 10 and a second display panel 20 that are in contact with each other, wherein an image 12 displayed by the first display panel 10 and an image 22 displayed by the second display panel 20 are present. There is a significant gap 30, and the gap 30 is substantially caused by the bezel of the first display panel 10 and the second display panel 20. In order to reduce the gap 30, the first display panel 10 and the second display panel 20 tend to adopt a narrow bezel design, but still cannot achieve an ideal display image.
本發明提供一種顯示裝置,具有無邊框設計且具有理想的邊緣顯示品質。 The present invention provides a display device having a frameless design and having an ideal edge display quality.
本發明的一種顯示裝置,包括第一基板、多個第一顯示畫素以及多個第二顯示畫素。第一基板至少具有第一平面區以及與第一平面區相鄰的第一彎折區。第一彎折區彎折成弧形而不平行於第一平面區。第一顯示畫素配置於第一基板的第一平面區中,且第一顯示畫素彼此之間的間距(pitch)為定值。第二顯示畫素配置於第一基板的第一彎折區中。第二顯示畫素彼此之間的間距由第一平面區與第一彎折區之間的一第一交界遠離第一平面區逐漸增加。 A display device of the present invention includes a first substrate, a plurality of first display pixels, and a plurality of second display pixels. The first substrate has at least a first planar region and a first bent region adjacent to the first planar region. The first bending zone is curved into an arc shape and is not parallel to the first plane zone. The first display pixels are disposed in the first planar region of the first substrate, and a pitch between the first display pixels is constant. The second display pixel is disposed in the first bending region of the first substrate. The spacing between the second display pixels is gradually increased from a first boundary between the first planar region and the first curved region away from the first planar region.
基於上述,本發明實施例的顯示裝置具有彎折區的顯示畫素與平面區的顯示畫素,且顯示裝置的彎折區彎折成不平行於平面區。彎折區的顯示畫素具有不一致的間距設計,以使得使用者觀看顯示畫面時可以感受到彎折區所呈現的顯示效果大致相同於平面區。將兩個顯示裝置的彎折區拼接在一起則可以獲得顯示品質良好的大尺寸顯示面板。 Based on the above, the display device of the embodiment of the present invention has a display pixel of the bending region and a display pixel of the planar region, and the bending region of the display device is bent to be non-parallel to the planar region. The display pixels of the bending zone have an inconsistent spacing design, so that the user can feel that the display effect of the bending zone is substantially the same as the plane area when viewing the display screen. By splicing the bending regions of the two display devices together, a large-sized display panel with good display quality can be obtained.

圖2為本發明第一實施例的顯示裝置的示意圖。請參照圖2,顯示裝置100包括基板110、多個第一顯示畫素120以及多個第二顯示畫素130。基板110至少具有第一平面區102以及與第一平面區102相鄰的第一彎折區104。第一彎折區104彎折成弧形而不平行於第一平面區102。第一顯示畫素120配置於基板110的第一平面區102中,且第一顯示畫素110彼此之間的間距(pitch)X為定值。第二顯示畫素130配置於第一基板110的第一彎折區104中。第二顯示畫素130彼此之間的間距Y由第一平面區102與第一彎折區104之間的第一交界106遠離第一平面區102逐漸增加。 2 is a schematic view of a display device according to a first embodiment of the present invention. Referring to FIG. 2 , the display device 100 includes a substrate 110 , a plurality of first display pixels 120 , and a plurality of second display pixels 130 . The substrate 110 has at least a first planar region 102 and a first folded region 104 adjacent to the first planar region 102. The first bend region 104 is curved into an arc shape and is not parallel to the first planar region 102. The first display pixels 120 are disposed in the first planar region 102 of the substrate 110, and the pitch X between the first display pixels 110 is constant. The second display pixel 130 is disposed in the first bending region 104 of the first substrate 110. The spacing Y between the second display pixels 130 is gradually increased from the first interface 106 between the first planar region 102 and the first bending region 104 away from the first planar region 102.
在本實施例中,第一顯示畫素120與第二顯示畫素130都是有機發光顯示畫素,但也可以選擇為電泳顯示畫素、電濕潤顯示畫素或是液晶顯示畫素。基板110具有可撓曲的特性,且第一彎折區104的基板110適於設置在預定彎折狀態下。在本實施 例中,第一彎折區104的彎折幅度大於90度,也就是第一彎折區104彎折成的弧面,其弧角大於90度,這使得顯示裝置100在第一彎折區104處具有無邊框的設計。也就是說,在第一彎折區104中的顯示畫面可以擴展至顯示裝置100的最寬外緣BD。 In this embodiment, the first display pixel 120 and the second display pixel 130 are both organic light emitting display pixels, but may also be selected as an electrophoretic display pixel, an electrowetting display pixel or a liquid crystal display pixel. The substrate 110 has a flexible property, and the substrate 110 of the first bending region 104 is adapted to be disposed in a predetermined bending state. In this implementation In the example, the first bending region 104 has a bending amplitude greater than 90 degrees, that is, the curved surface of the first bending region 104 is bent, and the arc angle is greater than 90 degrees, which causes the display device 100 to be in the first bending region. 104 has a borderless design. That is, the display screen in the first bending zone 104 can be expanded to the widest outer edge BD of the display device 100.
第二顯示畫素130彼此之間的間距Y的大小相關於第一彎折區104的彎折程度。特別是,間距(pitch)X或是Y可以視為一個顯示畫素的顯示面積的一側到下一個顯示畫素的顯示面積的一側,且顯示畫素的顯示面積正比於間距的大小。也就是說,在本實施例中,間距的增大表示顯示畫素的顯示面積也增大。具體而言,第一顯示畫素120彼此之間的間距X為定值X0,且第N個第二顯示畫素130與第N+1個第二顯示畫素130之間的間距Y為YN,則X0=YN*cosAN,其中N為正整數,且AN為第N個第二顯示畫素130與預定顯示平面108的夾角A。另外,AN實質上可替代為第N個第二顯示畫素130的中心點的切線與預定顯示平面108的夾角。以本實施例而言,預定顯示平面108例如為第一平面區102的外表面所在的平面。因此,第一平面區102平行於預定顯示平面108。也就是說,使用者觀看顯示裝置100所顯示的畫面時,會感受到畫面是呈現於預定顯示平面108上。在其他的實施例中,預定顯示平面108例如為行於第一平面區102的外表面的一個表面,並且預定顯示平面108與第一平面區102的外表面之間可以相隔一距離。預定顯示平面108在此可以視為顯示裝置100的顯示畫面所成像的平面。 The size of the pitch Y between the second display pixels 130 is related to the degree of bending of the first bending region 104. In particular, the pitch X or Y can be regarded as one side of the display area of the display pixel to the display area of the next display pixel, and the display area of the display pixel is proportional to the size of the pitch. That is, in the present embodiment, an increase in the pitch indicates that the display area of the display pixel also increases. Specifically, the spacing X between the first display pixels 120 is a fixed value X 0 , and the spacing Y between the Nth second display pixel 130 and the (N+1)th second display pixel 130 is Y N , then X 0 = Y N *cosA N , where N is a positive integer, and A N is the angle A between the Nth second display pixel 130 and the predetermined display plane 108. In addition, A N may be substantially substituted for the angle between the tangent of the center point of the Nth second display pixel 130 and the predetermined display plane 108. In the present embodiment, the predetermined display plane 108 is, for example, the plane in which the outer surface of the first planar region 102 is located. Thus, the first planar region 102 is parallel to the predetermined display plane 108. That is to say, when the user views the screen displayed by the display device 100, it is felt that the screen is presented on the predetermined display plane 108. In other embodiments, the predetermined display plane 108 is, for example, a surface that runs on the outer surface of the first planar region 102, and the predetermined display plane 108 and the outer surface of the first planar region 102 may be separated by a distance. The predetermined display plane 108 can here be regarded as a plane on which the display screen of the display device 100 is imaged.
在本實施例中,第一彎折區104上的第二顯示畫素130具有非均一的間距Y,且第二顯示畫素130的尺寸設計符合X0=YN*cosAN。第二顯示畫素130顯示畫面時,第二顯示畫素130所顯示的畫面垂直的投影至預定顯示平面108上的畫面寬度W會大致等於間距X的大小,即X0。因此,第二顯示畫素130顯示的畫面與第一顯示畫素120顯示的畫面在預定顯示平面108上具有相同的尺寸,而不會發生邊緣畫面變形或扭曲的現象,這有助於提升顯示裝置的顯示品質。 In this embodiment, the second display pixel 130 on the first bending region 104 has a non-uniform pitch Y, and the second display pixel 130 is sized to conform to X 0 =Y N *cosA N . When the second display pixel 130 displays a picture, the vertical width of the picture displayed by the second display pixel 130 onto the predetermined display plane 108 may be substantially equal to the size of the pitch X, that is, X 0 . Therefore, the picture displayed by the second display pixel 130 and the picture displayed by the first display pixel 120 have the same size on the predetermined display plane 108 without deformation or distortion of the edge picture, which helps to enhance the display. The display quality of the device.
圖3A為本發明第二實施例的顯示裝置的示意圖,而圖3B為圖3A的顯示裝置的區域F的局部放大示意圖。請參照圖3A與圖3B,顯示裝置200包括基板210、多個第一顯示畫素220以及多個第二顯示畫素230。基板210至少具有第一平面區202以及與第一平面區202相鄰的第一彎折區204。第一彎折區204彎折成弧形而不平行於第一平面區202。第一顯示畫素220配置於基板210的第一平面區202中,且第一顯示畫素210彼此之間的間距(pitch)X為定值。第二顯示畫素230配置於第一基板210的第一彎折區204中。第二顯示畫素230的間距Y大小會隨著第二顯示畫素230的位置而有所改變。在本實施例中,第二顯示畫素230彼此之間的間距Y由第一平面區202與第一彎折區204之間的第一交界206遠離第一平面區202而逐漸增加。間距(pitch)X或是Y可以視為一個顯示畫素的顯示面積的一側到下一個顯示畫素的顯示面積的一側,且顯示畫素的顯示面積正比於間距的大小。也就 是說,在本實施例中,間距的增大表示顯示畫素的顯示面積也增大。 3A is a schematic view of a display device according to a second embodiment of the present invention, and FIG. 3B is a partially enlarged schematic view of a region F of the display device of FIG. 3A. Referring to FIGS. 3A and 3B , the display device 200 includes a substrate 210 , a plurality of first display pixels 220 , and a plurality of second display pixels 230 . The substrate 210 has at least a first planar region 202 and a first folded region 204 adjacent the first planar region 202. The first bend region 204 is curved into an arc shape and is not parallel to the first planar region 202. The first display pixels 220 are disposed in the first planar region 202 of the substrate 210, and the pitch X between the first display pixels 210 is constant. The second display pixel 230 is disposed in the first bending region 204 of the first substrate 210. The pitch Y size of the second display pixel 230 may vary depending on the position of the second display pixel 230. In the present embodiment, the spacing Y between the second display pixels 230 is gradually increased by the first boundary 206 between the first planar region 202 and the first bending region 204 away from the first planar region 202. The pitch X or Y can be regarded as one side of the display area of the display pixel to the display area of the next display pixel, and the display area of the display pixel is proportional to the size of the pitch. Also That is to say, in the present embodiment, an increase in the pitch indicates that the display area of the display pixel also increases.
在本實施例中,第一顯示畫素220與第二顯示畫素230都是有機發光顯示畫素,但也可以選擇為電泳顯示畫素、電濕潤顯示畫素或是液晶顯示畫素。基板210具有可撓曲的特性,且第一彎折區204的基板210適於設置在預定彎折狀態下。在本實施例中,第一彎折區204的彎折幅度大於90度,也就是第一彎折區204彎折成的弧面,其弧角大於90度,這使得顯示裝置200在第一彎折區204處具有無邊框的設計。 In this embodiment, the first display pixel 220 and the second display pixel 230 are both organic light emitting display pixels, but may also be selected as an electrophoretic display pixel, an electrowetting display pixel or a liquid crystal display pixel. The substrate 210 has a flexible property, and the substrate 210 of the first bending region 204 is adapted to be disposed in a predetermined bending state. In this embodiment, the bending width of the first bending region 204 is greater than 90 degrees, that is, the curved surface of the first bending region 204 is bent, and the arc angle is greater than 90 degrees, which makes the display device 200 at the first The bend region 204 has a borderless design.
具體而言,第二顯示畫素230的間距Y依照以下條件設計。第二顯示畫素230由第一交界206遠離第一平面區202依序排列的數量為M而定義出M個畫素邊界232,其中M為正整數。將第一平面區202的外表面所在的平面設定為預定顯示平面208。在預定顯示平面208上設置由第一交界206向外依序排列的M個預定畫素邊界ZP,且預定畫素邊界ZP彼此間隔一設定間距Z。此時,第N個畫素邊界232與第N個預定畫素邊界ZP直線連接定義出虛擬的一虛連接線L,則可以設定需連接線L的傾斜程度使得M條虛連接線L向外延伸相交於一點U(繪示於圖3A中),其中N為正整數,而N為1~M其中一者。在其他的實施例中,預定顯示平面208例如為行於第一平面區202的外表面的一個表面,並且預定顯示平面208與第一平面區202的外表面之間可以相隔一距離。預定顯示平面208在此可以視為顯示裝置200的顯 示畫面所成像的平面。 Specifically, the pitch Y of the second display pixel 230 is designed in accordance with the following conditions. The second display pixel 230 defines M pixel boundaries 232 from the number of first boundaries 206 that are sequentially spaced away from the first planar region 202, where M is a positive integer. The plane in which the outer surface of the first planar region 202 is located is set to a predetermined display plane 208. M predetermined pixel boundaries ZP arranged outwardly by the first boundary 206 are disposed on the predetermined display plane 208, and the predetermined pixel boundaries ZP are spaced apart from each other by a set pitch Z. At this time, the Nth pixel boundary 232 and the Nth predetermined pixel boundary ZP are linearly connected to define a virtual virtual connection line L, and the inclination of the connection line L can be set such that the M virtual connection lines L are outward. The extension intersects at a point U (shown in Figure 3A), where N is a positive integer and N is one of 1~M. In other embodiments, the predetermined display plane 208 is, for example, one surface that runs on the outer surface of the first planar region 202, and the predetermined display plane 208 and the outer surface of the first planar region 202 may be separated by a distance. The predetermined display plane 208 can be regarded as the display device 200 here. The plane on which the picture is imaged.
在本實施例中,如果設定間距Z的大小等於第一顯示畫素220的間距X的大小,則使用者在點U觀看顯示裝置200所顯示的畫面時,第一平面區202所呈現的畫面與第一彎折區204所呈現的畫面會具有大致相同的解析度,不會發生邊緣畫面扭曲或變形的現象。同時,顯示裝置200也可以提供無邊框的顯示效果,也就是在第一彎折區204處顯示畫面可以擴展至顯示裝置200的最寬外緣。 In this embodiment, if the size of the set spacing Z is equal to the size of the spacing X of the first display pixel 220, the user presents the screen presented by the first planar area 202 when the user views the screen displayed by the display device 200 at the point U. The screen presented by the first bending zone 204 will have substantially the same resolution, and the phenomenon that the edge image is distorted or deformed does not occur. At the same time, the display device 200 can also provide a borderless display effect, that is, the display screen can be expanded to the widest outer edge of the display device 200 at the first bending region 204.
根據上述方式設置第二顯示畫素230的間距Y時,各第二顯示畫素230所顯示的畫面沿著使用者觀看的視角方向(例如虛連接線L的延伸方向)投影至預定顯示平面208具有所設定大小,且其大小可以等於第一顯示畫素220在預定顯示平面208上所顯示的畫面的大小(也就是第一顯示畫素220的間距X)。因此,第一彎折區204雖然不平行於第一平面區202,顯示裝置200所呈現的畫面不會發生邊緣畫面扭曲或變形的現象。 When the pitch Y of the second display pixel 230 is set in the above manner, the screen displayed by each of the second display pixels 230 is projected to the predetermined display plane 208 along the viewing direction (for example, the extending direction of the virtual connecting line L) viewed by the user. There is a set size, and its size may be equal to the size of the picture displayed on the predetermined display plane 208 by the first display pixel 220 (that is, the pitch X of the first display pixel 220). Therefore, although the first bending region 204 is not parallel to the first planar region 202, the image presented by the display device 200 does not suffer from distortion or deformation of the edge image.
另外,本實施例也可採用數學公式來推導第二顯示畫素230的間距Y與第二顯示畫素230所在位置的關係。由圖3A與圖3B可知,假設點U與預定顯示平面208具有垂直距離l,且點U垂直投影至預定顯示平面208上的點UP與第一交界206之間相隔水平距離h,則虛連接線L交於第一交界206的交點LP與預定顯示平面208相隔距離l’,且第N個交點LP的,其中N為第N個第二顯示畫素230的N且d為設定間距Z的大小。在本 實施例中,設定間距Z的大小(d)可以設計為等於第一顯示畫素220的間距X的大小。另外,第一彎折區204以點O作為曲率中心並且沿著曲率半徑r彎折時,第N個第二顯示畫素230所對應的預定畫素邊界ZP至第一交界206的距離ZN大小可以設置為Z N =N×d=r×sin θ N ×fn(公式1),其中θ N為第N個第二顯示畫素230與第一交界206之間的弧角。當預定顯示平面208即為第一平面區202的外表面時,。由公式1與公式2 可得到3)。之後,可獲得,第N個第二顯示畫素230所對應的間距Y的大小Y N =r×(θ N -θ N-1),其中θ N與θ N-1可以由公式3求得。 In addition, the present embodiment can also use a mathematical formula to derive the relationship between the pitch Y of the second display pixel 230 and the position of the second display pixel 230. 3A and 3B, it is assumed that the point U has a vertical distance l from the predetermined display plane 208, and the point U vertically projected onto the predetermined display plane 208 is separated from the first boundary 206 by a horizontal distance h, then the virtual connection The intersection L of the line L intersecting the first boundary 206 is separated from the predetermined display plane 208 by a distance l', and the Nth intersection point LP Where N is N of the Nth second display pixel 230 and d is the size of the set pitch Z. In the present embodiment, the size (d) of the set pitch Z may be designed to be equal to the size of the pitch X of the first display pixel 220.
