The FMLOC design refers to manufacturing a metal electrode layer on the packaging layer 17 of the display substrate, and the surface of the metal electrode layer significantly reflects ambient light. In order to improve the contrast ratio of the display panel and reduce reflected light, a polarizer is usually arranged on the light-emitting side of the light-emitting layer 16, so that the display panel appears black when it is not bright. However, the polarizer will cause the light intensity of the display panel to attenuate, and will cause the thickness of the display panel to be larger.

[0063] As shown in FIG. 1, in order to improve the light-emitting efficiency of the display panel at the normal viewing angle and reduce the thickness of the display panel, a first cover layer 191 is arranged on the side of the touch electrode layer away from the substrate 11, the first cover layer 191 includes a plurality of first cover portions 1911, the touch electrode layer includes a plurality of touch units, the first cover portion 1911 is arranged on the side of the first touch unit 1811 away from the substrate 11, the first cover portion 1911 covers the first touch unit 1811, and the first cover portions 1911 are arranged close to each other on the side of the first cover portion 1911 away from the substrate 11. The first cover layer 191 forms a light-adjusting opening 1912 between the first cover portions 1911. An optical shielding layer 192 is arranged on the side of the first cover layer 191 away from the substrate 11, the optical shielding layer 192 includes a plurality of optical shielding portions 1921, the optical shielding portions 1921 are arranged close to each other on the side of the optical shielding portion 1921 away from the substrate 11. The optical shielding layer 192 forms a light-transmitting opening 1922 between the optical shielding portions 1921, different color filter units 193 are arranged in each light-adjusting opening 1912, the color filter units 193 cover the side surface of the first cover portion 1911, and extend to the side of the first cover portion 1911 away from the substrate 11.

[0064] Because the width and thickness of the first touch unit 1811 are small, the side surface of the first cover portion 1911 is a bevel. The refractive index of the light filtering unit 193 is greater than the refractive index of the first cover portion 1911, so that the emergent light ray of the oblique viewing angle of the light emitting unit 162 can produce total reflection on the interface between the side surface of the first cover portion 1911 and the light filtering unit 193, deflect the emergent light ray of the oblique viewing angle to the direction of the normal viewing angle and exit, thereby improving the light output efficiency of the display panel in the normal viewing angle, so that there is no need to set a polarizer, the thickness of the display panel is reduced, and the thinning of the display panel is facilitated.

[0065] As shown in FIG. 2, the orthographic projection of the light adjustment opening 1912 on the driving back plate 10 is located in the orthographic projection of the light transmission opening 1922 on the driving back plate 10, and the center of the orthographic projection of the light adjustment opening 1912 on the driving back plate 10 coincides with the center of the orthographic projection of the light transmission opening 1922 on the driving back plate 10. As shown in FIGS. 3 and 4, because the frequency of the reflected light ray of the ambient light in the light transmission opening 1922 and the light adjustment opening 1912 is close, in the case of poor matching, the light wave S1 of the reflected light ray of the ambient light in the light transmission opening 1922 and the light wave S2 of the light adjustment opening 1912 are superimposed, the waveforms of the two light waves are superimposed at the wave crest, the interference is constructive to form a brighter optical stripe, and the wave crest and the wave trough of the two light waves are superimposed, the interference is destructive to form a darker optical stripe. Therefore, the optical interference is easy to cause the stripe defect of alternating bright and dark.

[0066] Based on this, the display panel provided by the embodiment of the present application is shown in FIGS. 5-21. The display panel includes a driving backplane 10, a pixel defining layer 15, a plurality of pixel electrodes 161, a plurality of light emitting units 162 of different colors, a common electrode 163, a first cover layer 191, a light filtering layer, and a light shielding layer 192. The pixel defining layer 15 is arranged on one side of the driving backplane 10. The pixel defining layer 15 includes a plurality of pixel defining portions. The pixel defining portions are arranged on the side of the pixel defining layer 15 that is close to each other. A pixel opening 151 is formed between the pixel defining portions. The plurality of pixel electrodes 161 are respectively arranged in different pixel openings 151. The plurality of light emitting units 162 of different colors are respectively arranged on the side of each pixel electrode 161 that is away from the driving backplane 10. The common electrode 163 is arranged on the side of the plurality of light emitting units 162 that is away from the driving backplane 10. The first cover layer 191 includes a plurality of first cover portions 1911.

The slope angle of the side surface of the first cover portion 1911 is less than 90 degrees. The light filtering layer includes light filtering units 193 of different colors. Each light filtering unit 193 is arranged in a different light adjusting opening 1912. The light filtering unit 193 covers the side surface of the first cover portion 1911. The orthogonal projection of the light filtering unit 193 on the driving backplane 10 covers the orthogonal projection of the light emitting unit 162 on the driving backplane 10. The refractive index of the light filtering unit 193 is greater than the refractive index of the first cover portion 1911. The light shielding layer 192 includes a plurality of light shielding portions 1921. The light shielding portions 1921 are arranged on the side of the first cover portion 1911 that is away from the driving backplane 10. A light transmission opening 1922 is formed between the light shielding portions 1921 that are close to each other. The orthogonal projection of the light adjusting opening 1912 on the driving backplane 10 is located in the orthogonal projection of the light transmission opening 1922 on the driving backplane 10. The center of the orthogonal projection of the light transmission opening 1922 on the driving backplane 10 is not coincident with the center of the orthogonal projection of the light adjusting opening 1912 on the driving backplane 10.

[0067] The display panel includes the first cover portion 1911 and the light shielding portion 1921. The light transmission opening 1922 is formed between the first cover portions 1911 that are close to each other. The light transmission opening 1922 is formed between the light shielding portions 1921 that are close to each other. The orthogonal projection of the light adjusting opening 1912 on the driving backplane 10 is located in the orthogonal projection of the light transmission opening 1922 on the driving backplane 10. The center of the orthogonal projection of the light transmission opening 1922 on the driving backplane 10 is not coincident with the center of the orthogonal projection of the light adjusting opening 1912 on the driving backplane 10. The frequency relationship between the light transmission opening 1922 and the light adjusting opening 1912 can be destroyed. The possibility of interference between the light wave of the light transmission opening 1922 and the light wave of the light adjusting opening 1912 can be avoided. Thus, the display picture can be eliminated from the stripe defect.

The second gate 1332 can be arranged on the side of the second gate insulating layer 1322 away from the substrate 11, and is opposite to the active layer 131. The materials of the first gate insulating layer 1321 and the second gate insulating layer 1322 are both insulating materials such as silicon oxide.

[0075] The thin film transistor can further include an interlayer dielectric layer 134 arranged on the side of the second gate 1332 away from the substrate 11, and the interlayer dielectric layer 134 can cover the second gate 1332 and the second gate insulating layer 1322. The first source / drain metal layer is arranged on the surface of the interlayer dielectric layer 134 away from the substrate 11, and can include the first source 135 and the drain 136, which are connected to the first active layer 131, for example, the first source 135 and the drain 136 are respectively connected to the two doped regions of the corresponding first active layer 131 through vias.

[0085] The light regulation layer 19 can further include a light shielding layer 192, the light shielding layer 192 including a plurality of light shielding portions 1921, the light shielding portions 1921 being disposed on a side of the first cover portions 1911 away from the driving backplate 10, a normal projection of the light shielding portions 1921 on the substrate 11 covering a normal projection of the first touch units 1811 on the substrate 11, that is, the normal projection of the first touch units 1811 on the substrate 11 being located within the normal projection of the light shielding portions 1921 on the substrate 11, and an area of the normal projection of the first touch units 1811 on the substrate 11 being less than an area of the normal projection of the light shielding portions 1921 on the substrate 11. The light shielding portions 1921 are adjacent to each other on a side, and a light transmission opening 1922 is formed between the light shielding portions 1921. A normal projection of the light regulation opening 1912 on the substrate 11 is located within a normal projection of the light transmission opening 1922 on the substrate 11.

[0086] The light regulation layer 19 can further include a light filtering layer, the light filtering layer including a plurality of light filtering units 193 of different colors, the light filtering units 193 being disposed in the light regulation openings 1912 formed by two adjacent first cover portions 1911, a thickness of the light filtering units 193 being greater than a thickness of the first cover portions 1911, the light filtering units 193 covering side surfaces of the first cover portions 1911 and a partial region of the light shielding portions 1921 disposed on a side of the first cover portions 1911 away from the substrate 11, a non-overlapping region of the first cover portions 1911 and the light filtering units 193 being a bare region, the light shielding portions 1921 being disposed in the bare region, and a distance between the light shielding portions 1921 and the light filtering units 193 being greater than 0. The display panel can further include a second cover layer 20, the second cover layer 20 covering the light filtering units 193 and the light shielding portions 1921 on a side away from the substrate 11, and a gap being formed between the light filtering units 193 and the light shielding portions 1921.

[0087] The light filtering units 193 of different colors include a first light filtering unit 1931, a second light filtering unit 1932, and a third light filtering unit 1933, the orthographic projection of the first light filtering unit 1931 on the substrate 11 covers the orthographic projection of the first light emitting unit 1621 on the substrate 11, the orthographic projection of the second light filtering unit 1932 on the substrate 11 covers the orthographic projection of the second light emitting unit 1622 on the substrate 11, and the orthographic projection of the third light filtering unit 1933 on the substrate 11 covers the orthographic projection of the third light emitting unit 1623 on the substrate 11.

[0088] The first covering part 1911 can adopt a low refractive resin material with a refractive index of 1.45-1.5, the refractive index of the first light filtering unit 1931 can be generally 1.65-1.85, and the refractive index of the second light filtering unit 1932 and the third light filtering unit 1933 can be generally 1.55-1.7. The refractive index of the light filtering unit 193 of the three colors is higher than the refractive index of the first covering part 1911, so that the reflected light of the ambient light at the oblique viewing angle can produce total reflection on the side surface of the first covering part 1911, and be deflected to the direction of the normal viewing angle and exit, thereby improving the light extraction efficiency at the normal viewing angle.

[0089] The display panel adopts the first covering part 1911 to insulate the first touch unit 1811, which can thin the thickness of the display panel. The exit light at the oblique viewing angle can produce total reflection on the side surface of the first covering part 1911, and be deflected to the direction of the normal viewing angle and exit, thereby improving the light extraction efficiency at the normal viewing angle without energy loss. Secondly, the shape of the first covering part 1911 is trapezoidal, and the side surface is a conventional slope with a slope angle that is easier to control.

[0090] The shape of the light adjusting opening 1912 is similar to that of the pixel opening 151, and the center of the light adjusting opening 1912 coincides with that of the pixel opening 151. The shape of the light transmitting opening 1922 is similar to that of the light adjusting opening 1912, and the center of the light transmitting opening 1922 is offset relative to the center of the light adjusting opening 1912, which can destroy the frequency relationship of the reflected light of the ambient light at the light transmitting opening 1922 and the light adjusting opening 1912. It should be noted that the shape similar means that the shape of the light transmitting opening 1922 is basically the same as that of the light adjusting opening 1912, only the size is different. For example, when the light adjusting opening 1912 is circular, the shape of the light transmitting opening 1922 is a circle surrounding the light adjusting opening 1912, when the light adjusting opening 1912 is triangular, the shape of the light transmitting opening 1922 is a triangle surrounding the light adjusting opening 1912, and when the light adjusting opening 1912 is elliptical, the shape of the light transmitting opening 1922 is an ellipse surrounding the light adjusting opening 1912.

[0091] In other feasible embodiments, the shape of the dimming opening 1912 may be different from the shape of the light-transmitting opening 1922. For example, the dimming opening 1912 may be circular, and the light-transmitting opening 1922 may be elliptical. This prevents the center of the orthographic projection of the dimming opening 1912 onto the drive backplate 10 from coinciding with the center of the orthographic projection of the light-transmitting opening 1922 onto the drive backplate 10, and also disrupts the frequency relationship between the reflected light from the ambient light in the light-transmitting opening 1922 and the dimming opening 1912.

[0092] As shown in Figures 6 to 21, the light-transmitting opening 1922 includes a first light-transmitting opening 1923, a second light-transmitting opening 1924, and a third light-transmitting opening 1925.

The first covering layer has n groups of dimming openings 1912 extending along a second direction and arranged along a first direction. The m-th... o Group 1922 light-transmitting openings relative to the mth o The offset direction of group dimming aperture 1912 is related to the mth e The offset direction of the light-transmitting opening 1922 relative to the dimming opening 1912 of the me group is different; or the nth group... o The offset direction of the light-transmitting opening 1922 relative to the no-th dimming opening 1912 is the same as that of the nth group. e Group 1922 light-transmitting openings relative to the nth e The offset directions of the dimming apertures 1912 are different; m and n are positive integers, m o and n o If m is an odd number e and n e It is an even number; the first direction and the second direction are perpendicular.

[0094] The size of all the first light-transmitting openings 1923 in the first direction can be equal to the size in the second direction, and the size of all the second light-transmitting openings 1924 in the first direction can be equal to the size in the second direction. o In the m groups of light-transmitting openings 1922, the size of the third light-transmitting openings 1925 in the first direction is smaller than the size in the second direction, the third light-transmitting openings 1925 are symmetrically arranged about the first direction, and the directions of the two adjacent third light-transmitting openings 1925 in the first direction are opposite. e In the m groups of light-transmitting openings 1922, the size of the third light-transmitting openings 1925 in the first direction is larger than the size in the second direction, the third light-transmitting openings 1925 are symmetrically arranged about the second direction, and the directions of the two adjacent third light-transmitting openings 1925 in the second direction are opposite.
