[0002] A polarizer (POL) can effectively reduce the reflectivity of a display panel under strong light, but it will lose nearly 58% of the light output. For an organic light emitting diode (OLED) display panel, this greatly increases its life burden, in addition, the polarizer is thick and fragile in material, which is also not conducive to the development of dynamic bending products.

The POL-less technology not only can improve the light output rate, but also can reduce the thickness of the film layer. The color filter is usually composed of color resistors of multiple different colors and a black matrix between the color resistors. However, in the process of manufacturing the color filter, different color resistors need different masks, and the number of masks is large, the process is complex, and the cost is high. SUMMARY

The active layer 121 is located above the substrate 110; the first gate insulating layer 131 is located on the side of the active layer 121 away from the substrate 110; the first gate 1221 is located on the side of the first gate insulating layer 131 away from the active layer 121; the second gate insulating layer 132 is located on the side of the first gate 1221 away from the first gate insulating layer 131; the second gate 1222 is located on the side of the second gate insulating layer 132 away from the first gate 1221; the interlayer insulating layer 140 is located on the side of the second gate 1222 away from the second gate insulating layer 132; the source-drain electrode 123 is located on the side of the interlayer insulating layer 140 away from the second gate 1222, wherein the source-drain electrode 123 comprises a source 1231 and a drain 1232, and the source 1231 and the drain 1232 are connected to the active layer 121 through vias, respectively; the first planarization layer 151 is located on the side of the source-drain electrode 123 away from the interlayer insulating layer 140; the metal connecting layer 160 is located on the side of the first planarization layer 151 away from the source-drain electrode 123, wherein the metal connecting layer 160 is connected to the source-drain electrode 123 through a via; and the second planarization layer 152 is located on the side of the metal connecting layer 160 away from the first planarization layer 151. It should be noted that Figure 1 The structure of the array substrate 100 shown in the figure is only one of the embodiments provided by the present application, and is not intended to limit the structure of the present application.

[0033] In the present application, the light-emitting functional layer 200 comprises an anode 210, a pixel definition layer 220, a light-emitting layer 230, a cathode 240 and an encapsulation layer 250.

[0034] The anode 210 is disposed on the side of the array substrate 100 near the color filter layer 310, and the anode 210 is electrically connected to the source and drain electrodes 123, so that the thin-film transistor 120 provides a driving voltage to the anode 210. For example, please refer to Figure 1 The anode 210 is located on the side of the second planarization layer 152 away from the metal interconnect layer 160. The anode 210 can be connected to the metal interconnect layer 160 through a via to achieve electrical connection with the source and drain electrodes 123.

[0035] A pixel definition layer 220 is disposed on the side of the array substrate 100 and the anode 210 near the color filter layer 310. The pixel definition layer 220 includes a plurality of first openings 221, each first opening 221 exposing at least a portion of the anode 210. Further details can be found in the following description. Figure 1 The pixel definition layer 220 may include a first sub-pixel definition layer 222 and a second sub-pixel definition layer 223 stacked together. The second sub-pixel definition layer 223 is located on the side of the first sub-pixel definition layer 222 away from the array substrate 100. The first sub-pixel definition layer 222 may be an organic material, and the second sub-pixel definition layer 223 may be a black organic material to prevent interference or color crossing of light from the light-emitting layer 230 in the adjacent first opening 221.

[0036] The light-emitting layer 230 is disposed within the first opening 221 and is located above the anode 210. The light-emitting layer 230 includes multiple sub-light-emitting layers, which can be one of a red sub-light-emitting layer 231 that emits red light, a green sub-light-emitting layer 232 that emits green light, or a blue sub-light-emitting layer 233 that emits blue light. The light-emitting layer 230 emits light under the influence of the electric field between the anode 210 and the cathode 240.

[0037] The cathode 240 is disposed on the side of the light-emitting layer 230 and the pixel definition layer 220 near the color filter layer 310, and the cathode 240 covers the light-emitting layer 230 and the pixel definition layer 220.

[0038] An encapsulation layer 250 is disposed between the cathode 240 and the color filter layer 310, and covers the cathode 240 to prevent moisture intrusion. The encapsulation layer 250 may include one or more organic or inorganic film layers. For example, please refer to... Figure 1 The encapsulation layer 250 may include a first inorganic film layer 251, an organic film layer 252 and a second inorganic film layer 253 stacked together to improve encapsulation performance.

[0039] In the present application, the light filtering functional layer 300 comprises a light filtering layer 310 formed by an organic material, and the organic material has the characteristic of selectively transmitting light in the waveband of 630-650 nm, 520-550 nm and 450-470 nm. Therefore, the light filtering layer 310 formed by the organic material can transmit light in the red waveband, green waveband and blue waveband, and block or absorb light in other wavebands except the above wavebands, so as to realize the color filter function instead of the traditional color filter film. Compared with the traditional color filter film formed by a plurality of materials such as red color resist, green color resist and blue color resist, the light filtering layer 310 of the present application can reduce 2-3 masks, and eliminate the mask process of red color resist, green color resist and blue color resist, so as to simplify the process of the display panel 10 and effectively reduce the cost. Further, the organic material can be a single-color organic photoresist material which can selectively transmit light in the waveband of 630-650 nm, 520-550 nm and 450-470 nm. For example, the organic material can be a gray organic photoresist whose color patch is gray and can selectively transmit light in the waveband of 630-650 nm, 520-550 nm and 450-470 nm, but is not limited thereto.

[0040] In some embodiments, referring to Figure 1 , the side of the light filtering layer 310 away from the light emitting functional layer 200 is a flat surface, i.e. the light filtering layer 310 can function as a planarization layer. Since the material of the light filtering layer 310 is an organic material, and the light filtering effect of red, green and blue light can be achieved without patterning, in the present embodiment, the light filtering layer 310 has the functions of light filtering and planarization, and the process of the planarization layer 150 on the color filter film can be eliminated, so as to further simplify the process and reduce the cost.

[0041] In some embodiments, referring to Figure 1 , the light filtering functional layer 300 further comprises a black matrix 320 disposed between the light filtering layer 310 and the light emitting functional layer 200, and the black matrix 320 comprises a plurality of second openings 321; wherein the orthographic projection of the first opening 221 on the array substrate 100 is located within the orthographic projection range of the second opening 321 on the array substrate 100. The black matrix 320 is located above the pixel definition layer 220 and between adjacent first openings 221, so as to avoid light emitted by the sub-light emitting layer in the adjacent first openings 221 from causing cross talk, and avoid problems such as color mixing, so as to ensure the display quality of the display panel 10.

[0042] In the above embodiment, the black matrix 320 can be configured to avoid crosstalk or color mixing, but part of the light emitted by the light-emitting layer 230 will also be blocked or absorbed by the black matrix 320, thereby reducing the light output. To solve the above problem, the present application can further improve the light filter layer 310 to further improve the light output of the display panel 10.

[0043] In some embodiments, referring to Figure 2 , the light filter layer 300 can further include a light adjustment layer 330, the light adjustment layer 330 is disposed on the side of the light filter layer 310 away from the light-emitting functional layer 200, and the refractive index n1 of the light adjustment layer 330 is greater than the refractive index n2 of the light filter layer 310; wherein the side of the light filter layer 310 away from the light-emitting functional layer 200 is provided with a plurality of grooves 311, and the orthographic projection of the first opening 221 on the array substrate 100 is located within the orthographic projection range of the groove 311 on the array substrate 100. In this embodiment, the light filter layer 310 is patterned to form a plurality of groove 311 structures on its surface, and the plurality of grooves 311 correspond one-to-one to the plurality of first openings 221. Meanwhile, a light adjustment layer 330 is additionally provided above the light filter layer 310, and the light adjustment layer 330 fills the grooves 311. Since the refractive index n1 of the light adjustment layer 330 is greater than the refractive index n2 of the light filter layer 310, when the incident angle θ of the light ray L incident on the sidewall 3112 (the interface between the light adjustment layer 330 and the light filter layer 310) of the groove 311 is greater than the critical angle C, the light ray L will be totally reflected on the sidewall 3112 of the groove 311. The light ray after total reflection will be emitted from the light-emitting side 101 of the display panel 10, which can effectively improve the light output efficiency of the display panel 10 and reduce the power consumption of the display panel 10. The critical angle C can be calculated by the formula sinC = n2 / n1.

[0044] Further, the difference between the refractive index n1 of the light adjustment layer 330 and the refractive index n2 of the light filter layer 310 can be adjusted to adjust the critical angle C, so that more light rays can be totally reflected to further improve the light output. For example, the difference between the refractive index n1 of the light adjustment layer 330 and the refractive index n2 of the light filter layer 310 can be increased, i.e. the light adjustment layer material and the light filter layer material with a larger refractive index difference are selected to reduce the critical angle C, wherein sinC = n2 / n1, n1 > n2. As can be seen from the above relationship, the greater the difference between n1 and n2, the smaller the critical angle C, so that more light rays can satisfy the condition that the incident angle θ is greater than the critical angle C, which can be totally reflected on the sidewall 3112 of the groove 311, thereby gathering part of the scattered light and increasing the light output, thereby improving the light output of the display panel 10 and reducing the power consumption of the display panel 10.

[0045] In some embodiments, referring to Figure 2The orthographic projection of the groove 311 on the array substrate 100 is located in the orthographic projection range of the second opening 321 on the array substrate 100, that is, the area of the second opening 321 is greater than the area of the groove 311, so as to avoid the black matrix 320 from shielding the light incident on the sidewall 3112 of the groove 311, increase the amount of light capable of being totally reflected on the sidewall 3112 of the groove 311, and further improve the light extraction efficiency.

[0046] In some embodiments, referring to Figure 2 The groove 311 includes a groove bottom 3111 and a sidewall 3112 arranged around the groove bottom 3111. The sidewall 3112 is perpendicular to the groove bottom 3111 (α = 90), or the sidewall 3112 is arranged to be inclined toward the center direction of the groove 311 (0° < α < 90°), where the angle between the sidewall 3112 and the plane where the groove bottom 3111 is located is α. Further, the angle α between the sidewall 3112 and the plane where the groove bottom 3111 is located ranges from 20° to 90°. When the angle α is in the above range, the light totally reflected by the sidewall 3112 can be emitted from the light emitting side 101 of the display panel 10, and the scattered light is gathered, thereby improving the light extraction efficiency of the display panel 10.

[0047] In some embodiments, at a large viewing angle, because the attenuation degrees of different wavelengths of light at different viewing angles are different, red, green, and blue lights cannot be synthesized into white light, thereby causing a large viewing angle color deviation problem. The present application can adjust the size of the angle α of the groove 311 corresponding to the sub-light emitting layer of different colors, so as to adjust the critical angle of the sidewall 3112 of the groove 311 corresponding to the sub-light emitting layer of different colors, thereby making the amounts of red, green, and blue light totally reflected different, so as to achieve the best matching of the attenuation degrees of red, green, and blue light at a large viewing angle, form white light, and improve the large viewing angle color deviation problem.

[0048] In some embodiments, referring to Figure 2 The side of the light adjustment layer 330 away from the light filtering layer 310 is a flat surface, that is, the light adjustment layer 330 has the functions of a light adjustment and planarization film layer. The material of the light adjustment layer 330 can be a transparent organic photoresist, but is not limited thereto.

[0049] In some embodiments, referring to Figures 1-2The display panel 10 further comprises a touch function layer 400 disposed between the light emitting function layer 200 and the light filtering function layer 300, and used for realizing a touch function of the display panel 10. The touch function layer 400 can comprise a plurality of touch units 410, and each touch unit 410 can comprise one or more metal traces. When the touch unit 410 comprises a plurality of metal traces, the metal traces are spaced apart by an inorganic film layer, and the metal traces are electrically connected by a via in the inorganic film layer. Specifically, the structure of the touch function layer 400 can refer to the prior art, which is not limited in the present application.

[0050] In some embodiments, referring to Figures 1-2 The touch unit 410 is disposed between the light emitting function layer 200 and the black matrix 320, and the orthographic projection of the touch unit 410 on the array substrate 100 is located in the orthographic projection coverage range of the black matrix 320 on the array substrate 100. Specifically, the black matrix 320 can cover the touch unit 410. By disposing the black matrix 320 above the touch function layer 400, the surface reflection caused by the touch trace can be reduced, and the influence of the reflected light on the performance of the display panel 10 can be avoided.

[0051] In some embodiments, referring to Figures 1-2 The display panel 10 further comprises a protective layer 500 disposed on a side of the light filtering function layer 300 away from the light emitting function layer 200. The protective layer 500 can be a functional protective film (Module Overcoat Layer, MOD), which is used for protecting the display panel 10 and preventing water vapor erosion and physical damage.

[0052] The present application further provides a display device comprising the display panel 10 as described above. The display device can be a mobile phone, a tablet computer, a computer, a television, etc., but is not limited thereto.
