This can change the frequency relationship of reflected ambient light in the light-transmitting opening and in the light-adjusting opening to avoid interference between light waves of the reflected ambient light in the light-transmitting opening and light waves of the reflected ambient light in the light-adjusting opening, thereby eliminating stripe defects in a displayed image. The present invention further provides a display device comprising the display panel described above.

[0062] The FMLOC (Flexible multi-Layer On Cell) design is currently mainstream in the field of OLED touch display. 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 portion 1911 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, and the optical shielding portions 1921 form a light-transmitting opening 1922 between the optical shielding portions 1921. Different color light filtering units 193 are arranged in each light-adjusting opening 1912, the light filtering 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, and thus 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, and thus 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, a brighter optical stripe is formed, and the wave crest and the wave trough of the two light waves are superimposed, the interference is destructive, a darker optical stripe is formed. Therefore, the optical interference is easy to cause the stripe defect of alternating light and dark.

[0066] Based on this, the display panel provided by the embodiment of the present application is shown in FIGS. 5-22. The display panel includes a driving backplate 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 disposed on one side of the driving backplate 10. The pixel defining layer 15 includes a plurality of pixel defining portions. The pixel defining portions are formed with pixel openings 151 between the sides of the pixel defining portions that are close to each other. The plurality of pixel electrodes 161 are respectively disposed in different pixel openings 151. The plurality of light emitting units 162 of different colors are respectively disposed on the side of each pixel electrode 161 that is away from the driving backplate 10. The common electrode 163 is disposed on the side of the plurality of light emitting units 162 that is away from the driving backplate 10. The first cover layer 191 includes a plurality of first cover portions 1911. The first cover portions 1911 are disposed on the side of the common electrode 163 that is away from the driving backplate 10. The first cover portions 1911 are formed with light adjusting openings 1912 between the sides of the first cover portions 1911 that are close to each other. The slope angle of the side of the first cover portions 1911 is less than 90 degrees. The light filtering layer includes light filtering units 193 of different colors. Each light filtering unit 193 is disposed in a different light adjusting opening 1912. The light filtering unit 193 covers the side of the first cover portion 1911. The orthogonal projection of the light filtering unit 193 on the driving backplate 10 covers the orthogonal projection of the light emitting unit 162 on the driving backplate 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 disposed on the side of the first cover portion 1911 that is away from the driving backplate 10. The light shielding portions 1921 are formed with light transmission openings 1922 between the sides of the light shielding portions 1921 that are close to each other. The orthogonal projection of the light adjusting opening 1912 on the driving backplate 10 is located within the orthogonal projection of the light transmission opening 1922 on the driving backplate 10. The light transmission opening 1922 has a first portion 1926 and a second portion 1927.

The first cover portion 1911 is arranged on the side of the first touch unit 1811 away from the substrate 11, and the first cover portion 1911 covers the first touch unit 1811. Adjacent two first cover portions 1911 form a light adjustment opening 1912, and the slope angle of the side surface of the first cover portion 1911 is less than 90 degrees.

[0085] The light control layer 19 can further include a light shielding layer 192, and the light shielding layer 192 includes a plurality of light shielding portions 1921. The light shielding portion 1921 is arranged on the side of the first cover portion 1911 away from the driving backboard 10. The orthographic projection of the light shielding portion 1921 on the substrate 11 covers the orthographic projection of the first touch unit 1811 on the substrate 11, that is, the orthographic projection of the first touch unit 1811 on the substrate 11 is located within the orthographic projection of the light shielding portion 1921 on the substrate 11, and the area of the orthographic projection of the first touch unit 1811 on the substrate 11 is smaller than the area of the orthographic projection of the light shielding portion 1921 on the substrate 11.

The orthographic projection of the light adjustment opening 1912 on the substrate 11 is located within the orthographic projection of the light transmission opening 1922 on the substrate 11.

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

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

[0088] The first covering portions 1911 can be made of a low refractive resin material with a refractive index of 1.45-1.5, the refractive index of the first filter units 1931 can be generally 1.65-1.85, and the refractive index of the second filter units 1932 and the third filter units 1933 can be generally 1.55-1.7. The refractive index of the filter units 193 of the three colors is higher than the refractive index of the first covering portions 1911, so that the reflected light of the ambient light at the oblique viewing angle can be totally reflected on the side surface of the first covering portions 1911 and deflected to the direction of the normal viewing angle for emission, thereby improving the light emission efficiency at the normal viewing angle.

[0089] The display panel can insulate the first touch units 1811 by the first covering portions 1911, thereby reducing the thickness of the display panel. The emitted light at the oblique viewing angle can be totally reflected on the side surface of the first covering portions 1911 and deflected to the direction of the normal viewing angle for emission, thereby improving the light emission efficiency at the normal viewing angle without energy loss. In addition, the first covering portions 1911 have a trapezoidal shape, and the side surface thereof is a conventional slope with a slope angle that is easier to control.

[0090] The distance between the first portion 1926 and the edge of the light-adjusting opening 1912 is a first distance, and the distance between the second portion 1927 and the edge of the light-adjusting opening 1912 is a second distance, and the first distance is not equal to the second distance. By misaligning the center of mass of the light-transmitting opening 1922 and the light-adjusting opening 1912, the frequency relationship between the reflected light of the ambient light and the light-transmitting opening 1922 and the light-adjusting opening 1912 can be changed, and the possibility of interference between the light wave of the light-transmitting opening 1922 and the light wave of the light-adjusting opening 1912 can be avoided, so as to eliminate the stripe defect of the display picture.

[0091] In the embodiment, the first portion 1926 of the light-transmitting opening 1922 can be convex relative to the second portion 1927, so that the first distance is greater than the second distance.

In other embodiments, the first portion 1926 of the light-transmitting opening 1922 can also be concave relative to the second portion 1927, so that the first distance is less than the second distance.

[0092] The shape of the light-adjusting opening 1912 is similar to the shape of the pixel opening 151, and the center of the light-adjusting opening 1912 coincides with the center of the pixel opening 151. It should be noted that similar shapes mean that the shape of the light-adjusting opening 1912 is basically the same as the shape of the pixel opening 151, 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 circular shape surrounding the pixel opening 151, when the light-adjusting opening 1912 is triangular, the shape of the light-transmitting opening 1922 is a triangular shape surrounding the pixel opening 151, and when the light-adjusting opening 1912 is elliptical, the shape of the light-transmitting opening 1922 is an elliptical shape surrounding the pixel opening 151.

[0093] The light-transmitting opening 1922 has a first portion 1926 and a second portion 1927, and the shape of the second portion 1927 of the light-transmitting opening 1922 is similar to the shape of the light-adjusting opening 1912 at the corresponding position. It should be noted that similar shapes mean that the shape of the light-transmitting opening 1922 is basically the same as the shape of the second portion 1927 of the light-transmitting opening 1922, only the size is different. For example: when the light-adjusting opening 1912 is circular, the shape of the second portion 1927 of the light-transmitting opening 1922 is a circular shape with a notch, when the light-adjusting opening 1912 is triangular, the shape of the second portion 1927 of the light-transmitting opening 1922 is a triangular shape with a notch, and when the light-adjusting opening 1912 is elliptical, the shape of the second portion 1927 of the light-transmitting opening 1922 is an elliptical shape with a notch.
