In the field of OLED (organic light emitting diode) display, a Color filter on EN (Color filter on EN) structure, which is a structure in which a Color film unit black matrix is directly formed on a film encapsulation layer, appears. According to the display panel based on the COE technology, a color film structure layer formed by a black matrix and a color film unit is adopted to replace a polarizer, and the thickness of the common polarizer is larger than 50 micrometers, while the thickness of the color film structure layer is generally smaller than 10 micrometers, so that compared with a conventional polarizer display panel, the display panel based on the COE technology is thinner and is easier to bend or curl.
In order to reduce the surface reflection of the screen, a black matrix is usually arranged in a COE structure, but the size of the black matrix affects the large viewing angle brightness of the screen, and people generally pursue higher large viewing angle brightness, so the size design of the black matrix needs to be balanced. Referring to fig. 1 to 3, in order to widen an application scenario of the OLED display panel, the present embodiment provides a display panel including:
an array substrate 1;
a pixel defining layer 2 disposed on the array substrate 1, the pixel defining layer 2 having a plurality of first opening regions and a non-opening region surrounding the first opening regions;
a light emitting layer 3 including sub-pixels disposed in the first opening area;
the packaging layer is positioned on one side of the light-emitting layer 3, which is far away from the array substrate 1;
the color film structure layer is positioned on one side, away from the array substrate 1, of the packaging layer and comprises a black matrix layer 42 and a color resistance layer;
the sub-pixels include a first color sub-pixel 31 and a second color sub-pixel 32;
the black matrix layer 42 has a second opened region 421 corresponding to the first color sub-pixel 31 and a third opened region 422 corresponding to the second color sub-pixel 32;
the length of the second opening region 421 in the first direction is a first length, the length of the first color sub-pixel 31 in the first direction is a second length, and the first length is smaller than the second length;
the length of the third opening region 422 in the first direction is a third length, the length of the second color sub-pixel 32 in the first direction is a fourth length, and the third length is greater than the fourth length, so that the color displayed in the first preset viewing angle range is the first color, the color displayed in the second preset viewing angle range is a third color, and the color displayed in the third preset viewing angle range is the second color;
the viewing angle when the viewing direction is perpendicular to the display panel is 0 degree, the viewing angle when the viewing direction is parallel to the display panel 100 is 90 degrees, and the 0-90 degrees are sequentially divided into three parts, namely a first preset viewing angle range, a second preset viewing angle range and a third preset viewing angle range, from small to large;
the first direction is a row direction or a column direction of the plurality of sub-pixels.
In this embodiment, the display panel includes a first color sub-pixel 31 and a second color sub-pixel 32, the second length of the first color sub-pixel 31 in the first direction is the same as the fourth length of the second color sub-pixel 32 in the first direction, the black matrix layer 42 has a second open area 421 corresponding to the first color sub-pixel 31 and a third open area 422 corresponding to the second color sub-pixel 32, the second open area 421 and the third open area 422 are configured differently, that is, the first length of the second open area 421 in the first direction is smaller than the second length, and the third length of the third open area 422 in the first direction is greater than the fourth length, so that the attenuation of the light of the first color in a large viewing angle can be increased, and a color synthesis principle is used, the display panel displays light of different colors at different viewing angles, specifically, the color displayed within a first preset viewing angle range is the first color, the color displayed within a second preset viewing angle range is a third color, and the color displayed within a third preset viewing angle range is the second color, where the third color is a color synthesized by the first color and the second color, for example, the first color is red, the second color is green, and the third color is yellow.
Fig. 4 shows a luminance decay curve of an RGB pixel in the COE structure in the related art, and the colors of the composite colors shown in fig. 4 do not change at viewing angles of 0 to 70 ° because the luminance of the RGB pixel decays as the viewing angle increases due to the microcavity effect and the influence of light shielding of the black matrix, which is the same in the arrangement of the opening areas corresponding to the sub-pixels of different colors, but the luminance decay ratio of the RGB pixel is almost the same. Fig. 5 shows the luminance attenuation curves of the first color sub-pixel and the second color sub-pixel in the embodiment, where a curve 10 shows the luminance attenuation curve of the first color sub-pixel, a curve 20 shows the luminance attenuation curve of the second color sub-pixel, and the first color sub-pixel 31 is a red sub-pixel, and the second color sub-pixel 32 is a green sub-pixel, as an example, after the second opening area 421 corresponding to the red sub-pixel is designed differently, the second opening area has no influence on the display color at the positive viewing angle of the display panel, and at a large viewing angle, for example, 45 °, the luminance of the red sub-pixel has been attenuated to 0, and at this time, the composite color displayed by the display panel has no contribution of the red sub-pixel, and the composite picture is contributed only by the green sub-pixel. Referring to fig. 6, it can be obtained in fig. 6 that the composite colors of the display panel at viewing angles of 0 °, 35 ° and 45 ° are obvious, and the colors of the pictures are completely different, wherein the colors are red at viewing angle of 0 degree, yellow at viewing angle of 35 degree, and green at viewing angle of 45 degree, and the color coordinates are as follows:
the color change locus of the viewing angle is plotted in the CIE1931 coordinate diagram (refer to fig. 6), so that the color change of the display screen can be observed directly according to the change of the viewing angle. The color displayed on the display screen changes from red to green to yellow within a viewing angle of 0-80 degrees. If the first color is green and the second color is red, the color displayed by the display panel 100 changes to green-yellow-red at viewing angles of 0-80 ° with reference to fig. 7.
To sum up, with the above technical solution, the display panel can be applied to a traffic signal lamp, the display panel is placed at an intersection, and the visual angle of the vehicle is changed by rotating the display panel, so that the switching between red, green and yellow signals can be realized, referring to fig. 11 and 12.
Illustratively, the orthographic projection of the second opening area 421 on the light emitting layer 3 is located in the middle of the first color sub-pixel 31, and the center line of the second opening area 421 in the first direction coincides with the center line of the first color sub-pixel 31 in the first direction.
In this embodiment, the second opening area 421 is provided to increase the attenuation of the first color light at a large viewing angle, and the above-mentioned scheme is adopted to make the light emission of the first color sub-pixel 31 on both sides of the center line in the first direction symmetrical.
Illustratively, the first length and the second length satisfy the following relationship:
wherein a is the first length and L is the second length.

In order to reduce the surface reflection (reflection to the external light) of the screen, a black matrix (i.e. the black matrix layer 42) is usually disposed in the COE structure, but the size of the black matrix affects the large viewing angle brightness of the screen, and people generally pursue higher large viewing angle brightness, so there is a trade-off in the size design of the black matrix.
