Detailed Description
Fig. 1 is a schematic top view of a display panel according to an embodiment of the invention. Referring to fig. 1, a light-shielding pattern 100 is applied to a display panel 1000. In the present embodiment, the display medium layer 128 (shown in fig. 4) of the display panel 1000 may be a liquid crystal. That is, the display panel 1000 may be a Liquid Crystal Display (LCD). However, the invention is not limited thereto, and in other embodiments, the display panel 1000 may also be an organic light-emitting diode (OLED) display or other suitable display devices. The light shielding pattern 100 is a so-called black matrix (BlackMatrix). In the present embodiment, the material of the light-shielding pattern 100 is, for example, black resin. However, the present invention is not limited thereto, and in other embodiments, the material of the light shielding pattern 100 is also a metal with low reflectivity or other suitable materials.
Fig. 2 illustrates the second light shielding portion 104 of the light shielding pattern 100 of fig. 1. Fig. 3 illustrates the first light shielding portion 102 of the light shielding pattern 100 of fig. 1. Referring to fig. 1, 2 and 3, the light shielding pattern 100 includes a first light shielding portion 102 and a second light shielding portion 104. The first light shielding portion 102 defines a plurality of main pixel regions 106 of the display panel 1000. In detail, in the present embodiment, the first light shielding portion 102 includes a plurality of light shielding sub-portions 102a and a plurality of light shielding sub-portions 102b extending in different directions. The light-shielding sub-portions 102a and the light-shielding sub-portions 102b are interlaced to form a mesh shape to define a plurality of opening areas, wherein the rectangular partial opening areas inside the plurality of opening areas are the plurality of main pixel areas 106. In the embodiment, the main pixel region 106 may be a rectangle having a long side L1 and a short side S1, the long side L1 of the main pixel region 106 is defined as a long side of the pixel electrode 130, and the short side S1 of the main pixel region 106 is defined as a short side of the pixel electrode 130, for example, but the invention is not limited thereto. In another variation, the long side L1 of the main pixel region 106 is defined as the long side of the opening region, and the short side S1 of the main pixel region 106 is defined as the short side of the opening region, but the invention is not limited thereto.
The second light shielding portion 104 is adjacent to the first light shielding portion 102. The second light shielding portion 104 shields a frame region (border) of the display panel 1000. The second light-shielding portion 104 has an inner edge 104a to define a non-rectangular display area of the display panel 100. The inboard edge 104a is not a sharp (Zag) edge and/or a jagged edge. In the present embodiment, the inner edge 104a is, for example, an arc. By designing the shape of the inner edge 104a of the second light shielding portion 104, the display panel 100 can have a display area of an arbitrary shape (free-form). The first light shielding portion 102 and the inner edge 104a of the second light shielding portion 104 together define a plurality of non-rectangular pixel regions 108. In detail, in the present embodiment, each non-rectangular pixel region 108 can be surrounded by the first shielding portion 102 and a portion of the inner edge 104 a.
The non-rectangular pixel region 108 includes a first non-rectangular pixel region 108A and a second non-rectangular pixel region 108B that are adjacent and have different areas. Furthermore, in the present embodiment, the non-rectangular pixel region 108 may further include a third non-rectangular pixel region 108C. The first non-rectangular pixel region 108A, the second non-rectangular pixel region 108B and the third non-rectangular pixel region 108C are arranged in sequence, and the area of the first non-rectangular pixel region 108A, the area of the second non-rectangular pixel region 108B and the area of the third non-rectangular pixel region 108C are different from each other, but the invention is not limited thereto.
Each edge pixel region 136 includes at least a first non-rectangular pixel region 108A and a second non-rectangular pixel region 108B. The first non-rectangular pixel region 108A has a first color sub-region C1 capable of displaying a first color and a first white sub-region W1 capable of displaying white. The second non-rectangular pixel region 108B has a second color sub-region C2 capable of displaying a second color and may not have a white sub-region, where the first color is different from the second color. Notably, the area of first non-rectangular pixel region 108A minus the area of first white sub-region W1 is substantially equal to the area of second color sub-region C2 of second non-rectangular pixel region 108B. In other words, in the same edge pixel region 136, the area of first color sub-region C1 is substantially the same as the area of second color sub-region C2. Therefore, in each edge pixel region 136, the ratio of the area capable of displaying the first color to the area capable of displaying the second color is fixed, and the rainbow texture phenomenon described in the prior art can be effectively improved in the case of the non-sharp (Zag) edge and/or the jagged edge of the inner edge 104 a.
In a variation, the second non-rectangular pixel region 108B may further have a second white sub-region W2 capable of displaying white. By adjusting the area of the first white sub-region W1 and the area of the second white sub-region W2, the area of the first non-rectangular pixel region 108A minus the area of the first white sub-region W1 may be substantially equal to the area of the second non-rectangular pixel region 108B minus the area of the second white sub-region W2. That is, the area of first color sub-region C1 is substantially the same as the area of second color sub-region C2. The relationship between the area of the first white sub-area W1 and the area of the second white sub-area W2 is not particularly limited. In the present embodiment, the area of the first white sub-region W1 and the area of the second white sub-region W2 may be different. However, the present invention is not limited thereto, and in other embodiments, the area of the first white sub-region W1 and the area of the second white sub-region W2 may be the same. It should be noted that, by disposing the first white sub-region W1 and/or the second white sub-region W2, while improving the sharp (Zag) edge and rainbow streak phenomena, the overall brightness of the edge pixel region 136 is not easily reduced due to the small overall area and the small edge of the display region disposed on the display panel 1000. This contributes to improving the display effect of the entire display panel 1000 (especially, near the frame region).
In the present embodiment, each edge pixel region 136 further includes a third non-rectangular pixel region 108C. Third non-rectangular pixel region 108C has a third color sub-region C3 capable of displaying a third color, wherein the third color is different from the first color and the second color. Notably, the area of first non-rectangular pixel region 108A minus the area of first white sub-region W1 is substantially equal to the area of third color sub-region C3 of third non-rectangular pixel region 108C. In other words, in the same edge pixel region 136, the area of the first color sub-region C1, the area of the second color sub-region C2, and the area of the third color sub-region C3 of the non-rectangular pixel region 108C are substantially the same. Therefore, in each edge pixel region 136, the ratio of the area capable of displaying the first color, the area capable of displaying the second color and the area capable of displaying the third color is fixed, so that the rainbow streak phenomenon described in the prior art can be effectively improved in the case of the non-sharp (Zag) edge and/or the jagged edge of the inner edge 104 a. Furthermore, in the embodiment of fig. 1, the third non-rectangular pixel region 108C may optionally have a white sub-region W3. However, the invention is not limited thereto, and in other embodiments, the third non-rectangular pixel region 108C may not have the white sub-region W3.
In a variation, the third non-rectangular pixel region 108C may further have a third white sub-region W3 capable of displaying white. The area of the first non-rectangular pixel region 108A minus the area of the first white sub-region W1 is substantially equal to the area of the third non-rectangular pixel region 108C minus the area of the third white sub-region W3. In the present embodiment, the first white sub-region W1, the second white sub-region W2, and the third white sub-region W3 are adjacent to the main pixel region 106; the areas of the first white sub-region W1, the second white sub-region W2 and the third white sub-region W3 may be different from each other, so that the areas of the first color sub-region C1, the second color sub-region C2 and the third color sub-region C3 in the single edge pixel region 136 are the same, but the invention is not limited thereto.
As shown in fig. 1, in the present embodiment, the first color sub-region C1, the first white sub-region W1, the second color sub-region C2, the second white sub-region W2, the third color sub-region C3 and the third white sub-region W1 may all be non-rectangular. In detail, a boundary line is formed between each color sub-region and the corresponding white sub-region (e.g., between the first color sub-region C1 and the corresponding first white sub-region W1) and partially corresponds to the inner edge 104a, so that the area ratio of the light-emitting colors of each edge pixel region 136 is fixed.
In the present embodiment, each edge pixel region 136 includes a first non-rectangular pixel region 108A, a second non-rectangular pixel region 108B and a third non-rectangular pixel region 108C, and the first non-rectangular pixel region 108A, the second non-rectangular pixel region 108B and the third non-rectangular pixel region 108C respectively include a first color sub-region C1 capable of displaying a first color, a second color sub-region C2 capable of displaying a second color and a third color sub-region C3 capable of displaying a third color. In the present embodiment, the first color, the second color and the third color can be red, green and blue, respectively, but the invention is not limited thereto. In addition, in the present embodiment, the plurality of main pixel regions 106 located in the same row as the first color sub-region C1 of the first non-rectangular pixel region 108A can selectively display the first color, the plurality of main pixel regions 106 located in the same row as the second color sub-region C2 of the second non-rectangular pixel region 108B can selectively display the second color, and the plurality of main pixel regions 106 located in the same row as the third color sub-region C3 of the third non-rectangular pixel region 108C can selectively display the third color. However, the present invention is not limited thereto, and in another embodiment, the plurality of main pixel regions 106 in the same row as the first color sub-region C1 can selectively display other colors, the plurality of main pixel regions 106 in the same row as the second color sub-region C2 can selectively display other colors, and the plurality of main pixel regions 106 in the same row as the third color sub-region C3 can selectively display other colors.
FIG. 4 is a cross-sectional view of the display panel of FIG. 1 corresponding to the sectional line I-I' according to an embodiment of the present invention.
Referring to fig. 1 and 4, for convenience of illustration, fig. 4 only shows a portion of the first color sub-region C1 and a portion of the first white sub-region W1. The display panel 1000 includes a first substrate 110, an active device 118, at least one insulating layer (such as, but not limited to, a first insulating layer 120 and a second insulating layer 122), a pixel electrode 130, a support structure 126, a display medium layer 128, a color filter pattern CF, a light shielding pattern 100, and a second substrate 132. In the present embodiment, the display medium layer 128 may be a non-self-luminous material (e.g., liquid crystal), a color filter pattern CF corresponding to the first color may be disposed in a color sub-region (e.g., the first color sub-region C1) of each non-rectangular pixel region 108 (e.g., the first non-rectangular pixel region 108A), and no color filter pattern CF may be disposed in a white sub-region (e.g., the first white sub-region W1) of each non-rectangular pixel region 108 (e.g., the first non-rectangular pixel region 108A). In the present embodiment, the color filter pattern CF may be disposed on the second substrate 132. However, the invention is not limited thereto, and in other embodiments, the color filter pattern CF may be disposed on the first substrate 110 to be stacked with the active devices 118 to form a color filter on array (COA) structure.
The active device 118 is disposed on the first substrate 110. The active device 118 includes, but is not limited to, a thin film transistor. The thin film transistor has a source S, a gate G, a drain D and at least one semiconductor layer 114. The source S and the drain D are electrically connected to both sides of the semiconductor layer 114. More specifically, the active device 118 further includes an ohmic contact layer 116, and the source S and the drain D can be electrically connected to two sides of the semiconductor layer 114 through the ohmic contact layer 116. The gate electrode G overlaps the semiconductor layer 114. A gate insulating layer 112 may be disposed between the source S/drain D and the gate G to electrically isolate the source S/drain D from the gate G. In the present embodiment, the gate electrode G may be disposed between the semiconductor layer 114 and the first substrate 110. In other words, the gate G may be disposed below the semiconductor layer 114, and the active device 118 is, for example, a bottom gate thin film transistor (bottom gate TFT). However, the invention is not limited thereto, and in other embodiments, the active device 118 may also be a top gate thin film transistor (top gate TFT) or other suitable thin film transistors.
At least one insulating layer (such as, but not limited to, the first insulating layer 120 and the second insulating layer 122) covers the active device 118 and has an opening 134 exposing the drain D. The pixel electrode 130 is disposed on the second insulating layer 122 and electrically connected to the drain D through the opening 134.
The supporting structure 126 is disposed between the first substrate 110 and the second substrate 132 for maintaining a gap (cell gap) between the first substrate 110 and the second substrate 132, and the display medium layer 128 is disposed in the gap. It is noted that the thickness of the portion of the display medium layer 128 of the white sub-region (e.g., the first white sub-region W1) of each non-rectangular pixel region 108 (e.g., the first non-rectangular pixel region 108A) is T1, and the thickness of the portion of the display medium layer 128 of the color sub-region (e.g., the first color sub-region C1) of each non-rectangular pixel region 108 (e.g., the first non-rectangular pixel region 108A) is T2, and T1 is smaller than T2. Therefore, the brightness of each white sub-area of each non-rectangular pixel area is close to or even the same as that of each color sub-area, thereby further improving the display effect.
