As shown in Figure 3 and Figure 4, standard display pixel 20 and the first edge display pixel 30 are arranged in non-rectangle viewing area 11.Standard display pixel 20 is the main display pixel of relative majority in display device 101, and whole standard display pixels 20 or at least most standard display pixel 20 are not disposed adjacent with non-rectangular outlines line 11C.Comparatively speaking, the first edge display pixel 30 is disposed adjacent with non-rectangular outlines line 11C, and the first edge display pixel 30 is arranged between at least one standard display pixel 20 and non-rectangular outlines line 11C.The area of the first edge display pixel 30 is greater than the area of standard display pixel 20.Illustrate further, each standard display pixel 20 can comprise multiple standard sub-pixel 21 such as the first color standard sub-pixel 21A, the second color standard sub-pixel 21B and the 3rd color standard sub-pixel 21C, and the first edge display pixel 30 can comprise multiple first edge subpixel 31 such as the first color first edge subpixel 31A, the second color first edge subpixel 31B and the 3rd color first edge subpixel 31C.The first above-mentioned color, the second color and the 3rd color can be respectively red, green and blue, but not as limit.In other words, the standard display pixel 20 of the present embodiment can by three be respectively red, green and blue standard sub-pixel 21 form and there is full-color display effect, and the first edge display pixel 30 can by three be respectively red, the first green and blue edge subpixel 31 form and also there is full-color display effect, but the present invention is not as limit.In other embodiments of the invention, also the standard display pixel and edge display pixel with full-color display effect can be formed by other varying numbers (such as more than 2) and the sub-pixel with different color developing effect (such as white, yellow, carmetta or cyan).In addition, in the present embodiment, standard sub-pixel 21 can be a strip sub-pixel and extends along a first direction Y, and in standard display pixel 20, standard sub-pixel 21 is arranged along a second direction X repeated arrangement.First direction Y is orthogonal with second direction X substantially, but not as limit.The standard display pixel 20 of the present embodiment can be rectangle display pixel, and the first edge display pixel 30 can be non-rectangle display pixel, but the present invention is not as limit.In other embodiments of the invention, when with the first edge display pixel 30 be close to the partial sector non-rectangular outlines line 11C that arranges parallel with first direction Y or second direction X substantially time, the first edge display pixel 30 now also can be rectangle display pixel.
In order to avoid the elemental area that the edge display pixel affected by non-rectangular outlines line 11C is remaining is too little so that cannot use, and then making outline line become unsmooth when showing and present harsh feeling, the present embodiment can make to be close to non-rectangular outlines line 11C the too little display pixel of the script area that arranges and adjacent standard display pixel 20 and merges and become the first edge display pixel 30 that area is greater than standard display pixel 20.In other words, the first edge display pixel 30 is close to non-rectangular outlines line 11C and arranges, and does not arrange any other standard display pixel 20 between the first edge display pixel 30 and non-rectangular outlines line 11C.For example, the first edge display pixel 30 of the present embodiment can be regarded as merging with a standard display pixel 20 adjacent on first direction Y form by being close to non-rectangular outlines line 11C the imperfect display pixel that arranges, therefore the length of the first edge display pixel 30 on first direction Y is greater than the length of standard display pixel 20 on first direction Y, but the present invention is not as limit.In other embodiments of the invention, also optionally can make to be close to non-rectangular outlines line 11C the imperfect display pixel arranged merge with a standard display pixel 20 adjacent on second direction X and become the first edge display pixel 30 that area is greater than standard display pixel 20.
In addition, in order to avoid the problem of edge display pixel generation color inequality, in the first edge display pixel 30, the viewing area area ratio of each first edge subpixel 31 preferably equals the viewing area area ratio of each standard sub-pixel 21 in standard display pixel 20.The area of above-mentioned standard display pixel 20 and the area of the first edge display pixel 30 refer to the area of standard display pixel 20 and the profile area of the first edge display pixel 30, and viewing area area then refers to the actual region area carrying out showing in the area of standard display pixel 20 and the first edge display pixel 30.Such as, in organic LED display device, the viewing area area of each sub-pixel can by the size of organic light emitting material and may be overlapping with organic light emitting material shading object defined; And in liquid crystal indicator, the viewing area area of each sub-pixel can be defined by the aperture opening ratio of pixel electrode, but not as limit.For example, when the viewing area area ratio of the first color standard sub-pixel 21A, the second color standard sub-pixel 21B in standard display pixel 20 and the 3rd color standard sub-pixel 21C is 1:1:1, the first color first edge subpixel 31A, the second color first edge subpixel 31B in first edge display pixel 30 and the viewing area area ratio of the 3rd color first edge subpixel 31C are also preferably 1:1:1, avoid the first edge display pixel 30 that the problem of color inequality occurs thus, but the present invention is not as limit.In other embodiments of the invention, also visual color conditioning needs or other designs are considered (brightness of such as different colours and luminescent lifetime are not equal) and make the first color standard sub-pixel 21A in standard display pixel 20, the viewing area area of the second color standard sub-pixel 21B and the 3rd color standard sub-pixel 21C is incomplete same, and in this situation, the first color first edge subpixel 31A in first edge display pixel 30, the viewing area area ratio of the second color first edge subpixel 31B and the 3rd color first edge subpixel 31C also preferably equals the viewing area area ratio of each standard sub-pixel 21 in standard display pixel 20, therefore the first color first edge subpixel 31A, second color first edge subpixel 31B and the 3rd color first edge subpixel 31C wherein at least one also can have the viewing area area of different size.For example, when the viewing area area ratio of the first color standard sub-pixel 21A, the second color standard sub-pixel 21B in standard display pixel 20 and the 3rd color standard sub-pixel 21C is 1:1:2, the first color first edge subpixel 31A, the second color first edge subpixel 31B in the first edge display picture element 30 and the viewing area area ratio of the 3rd color first edge subpixel 31C are also preferably 1:1:2.In addition, the viewing area area of the first edge subpixel 31 is greater than the viewing area area of the standard sub-pixel 21 of corresponding same color in standard display pixel 20, but not as limit.
As shown in Figure 3 and Figure 4, the display device 101 of the present embodiment also can comprise at least one second edge display pixel 40 and be arranged in non-rectangle viewing area 11, and the second edge display pixel 40 is disposed adjacent with non-rectangular outlines line 11C.Second edge display pixel 40 is arranged at 11C between at least one standard display pixel 20 and non-rectangular outlines line, and the area of the second edge display pixel 40 is less than the area of standard display pixel 20.Second edge display pixel 40 is close to non-rectangular outlines line 11C and arranges, and does not arrange any other standard display pixel 20 between the second edge display pixel 40 and non-rectangular outlines line 11C.Second edge display pixel 40 can comprise multiple second edge subpixel 41 such as the first color second edge subpixel 41A, the second color second edge subpixel 41B and the 3rd color second edge subpixel 41C.In second edge display pixel 40, the viewing area area ratio of each second edge subpixel 41 preferably equals the viewing area area ratio of each standard sub-pixel 21 in standard display pixel 20, can avoid the problem that color inequality occurs when the cutting asymmetric by non-rectangular outlines line 11C of the second edge display pixel 40 thus.For example, when the viewing area area ratio of the first color standard sub-pixel 21A, the second color standard sub-pixel 21B in standard display pixel 20 and the 3rd color standard sub-pixel 21C is 1:1:1, the first color second edge subpixel 41A, the second color second edge subpixel 41B in second edge display pixel 40 and the viewing area area ratio of the 3rd color second edge subpixel 41C are also preferably 1:1:1, avoid the second edge display pixel 40 that the problem of color inequality occurs thus, but the present invention is not as limit.In other embodiments of the invention, also visual color conditioning needs or other designs are considered and make the first color standard sub-pixel 21A in standard display pixel 20, the viewing area area of the second color standard sub-pixel 21B and the 3rd color standard sub-pixel 21C is incomplete same, and in this situation, the first color second edge subpixel 41A in second edge display pixel 40, the viewing area area ratio of the second color second edge subpixel 41B and the 3rd color second edge subpixel 41C also preferably equals the viewing area area ratio of each standard sub-pixel 21 in standard display pixel 20, therefore the first color second edge subpixel 41A, second color second edge subpixel 41B and the 3rd color second edge subpixel 41C wherein at least one also can have the viewing area area of different size.In addition, the viewing area area of the second edge subpixel 41 is less than the corresponding viewing area area with the standard sub-pixel 21 of color in standard display pixel 20, but not as limit.
When designing edge display pixel, if when being greater than a predetermined percentage of standard display pixel 20 area by the elemental area that the edge display pixel of non-rectangular outlines line 11C impact is remaining, then this edge display pixel is designed to the second edge display pixel 40; Relatively, if when being less than the predetermined percentage of above-mentioned standard display pixel 20 area by the remaining elemental area of edge display pixel that non-rectangular outlines line 11C affects, then this edge display pixel and adjacent standard display pixel 20 must being merged and become the first edge display pixel 30.Above-mentioned predetermined percentage viewable design is considered and between 30% to 70%, but not as limit.For example, as shown in Figure 5, the area of the 3rd edge display pixel 50 in display device 100 is less than 30% of standard display pixel 20 area because being subject to the impact of non-rectangular outlines line 11C, therefore when above-mentioned predetermined percentage is 30%, the 3rd edge display pixel 50 can be merged with adjacent standard display pixel 20 and become the first edge display pixel 30 shown in Fig. 4.Therefore, when predetermined percentage is 30%, the area of the first edge display pixel 30 can be less than 130% of the area of standard display pixel 20, and the area of the second edge display pixel 40 can be more than or equal to 30% of the area of standard display pixel 20.Similarly, when predetermined percentage is 70%, the area of the first edge display pixel 30 can be less than 170% of the area of standard display pixel 20, and the area of the second edge display pixel 40 can be more than or equal to 70% of the area of standard display pixel 20.
By the first edge display pixel 30 of the present embodiment and the setting of the second edge display pixel 40, when non-rectangular outlines line 11C is with different angles cut edge display pixel, still can guarantee that the edge wheel profile place of non-rectangle viewing area 11 can not produce display harsh feeling and the unequal problem of color.In addition, above-mentioned viewing area area may be affected by different Physical design factors in different types of display device.For example, in organic LED display device, the viewing area area of each sub-pixel can by the size of organic light emitting material and may be overlapping with organic light emitting material shading object defined; On the other hand, in liquid crystal indicator, the viewing area area of each sub-pixel can be defined by pixel electrode, common electrode, colored filter and possible shading object (such as blackmatrix), but not as limit.
