The present application is described in detail below with reference to the figures and alternative embodiments.

The first embodiment is as follows:

fig. 1 is a schematic diagram of a display panel according to a first embodiment of the present application, and as can be seen from fig. 1, as a first embodiment of the present application, a display panel 200 is disclosed, which includes a substrate 210, a plurality of anodes 220 and a light-emitting layer 240, the plurality of anodes 220 are arranged in an array on the substrate 210, the light-emitting layer 240 is disposed on the anodes 220, the display panel 200 further includes a pixel defining layer 230, a first light-shielding layer 221 and a cathode 250, the first light-shielding layer 221 is disposed on the plurality of anodes 220 and covers two ends of the anodes 220 to form first openings 223 on the anodes 220; the pixel defining layer 230 is disposed on the substrate 210, covers the first light shielding layer 221, and exposes the first opening 223, and the light emitting layer 240 is disposed in the first opening 223; the cathode 250 is disposed on the light emitting layer 240 and the pixel defining layer 230.

For the scheme that the visual effect is influenced by light reflection at the two ends of the anode, the first light shielding layers 221 are arranged at the two ends of the anode 220, so that light reflection at the two ends of the anode 220 is prevented, and the influence of reflection of ambient light at the two ends of the anode 220 on the display effect is avoided; meanwhile, the pixel definition layer 230 separates the light emitting layers 240 on the plurality of anodes 220 to realize a pixel array, so that the display panel 200 normally displays a picture, and the anodes 220 and the cathodes 250 are separated by the pixel definition layer 230 and the first light shielding layer 221 corresponding to two ends of the anodes 220, thereby not only preventing a short circuit between the anodes 220 and the cathodes 250, but also reducing the phenomenon that the pixel definition layer 230 absorbs part of light to reduce the light extraction efficiency by the first light shielding layer 221, and further improving the overall performance of the display panel 200 to improve the visual effect and the experience of users.

Specifically, the first light shielding layer 221 is made of a black photoresist material.

In this embodiment, the display panel 200 is an OLED display panel 200, the substrate 210 may be a thin film transistor array substrate, and the anode 220 and the cathode 250 may be made of conductive materials such as Indium Tin Oxide (ITO) and silver (Ag); the pixel defining layer 230 can be made of a general Polyimide (PI) material, which has an insulating effect, and separates the light emitting layers 240 to achieve the effect of a pixel array; the light emitting layers 240 on the plurality of anodes 220 are light emitting layers 240 with three colors of red, blue or green arranged at intervals, or the light emitting layers 240 with all colors of white, and the light emitting layers 240 emit light normally under the action of the cathodes 250 and the anodes 220, so as to realize display of images.

The first light shielding layer 221 is made of a black photoresist material and covers two ends of the anode 220, so that a light shielding effect is achieved at two ends of the anode 220, the first light shielding layer 221 can be only arranged right above two ends of the anode 220, a first opening 223 is formed in the middle of the anode 220, the light emitting layer 240 is arranged in the first opening 223, the problem of light reflection at two ends of the anode 220 can be better prevented, and the display effect of the display panel 200 is better; in addition, the first light-shielding layer 221 occupies a portion of the thickness of the pixel defining layer 230, and can reduce the light absorption of the pixel defining layer 230, thereby improving the light extraction efficiency of the light-emitting layer 240. Moreover, after the first light-shielding layer 221 is manufactured, some surface treatment, such as carbonization, is performed on the first light-shielding layer 221, so that the first light-shielding layer 221 has a certain insulating effect, and also can achieve the effects of implementing a pixel array and preventing the anode 220 and the cathode 250 from being shorted.

In addition, the display panel 200 further includes a support layer 231, the support layer 231 is disposed on the pixel defining layer 230 and located between the pixel defining layer 230 and the cathode 250, and an orthogonal projection of the support layer 231 on the substrate 210 does not overlap an orthogonal projection of the first light shielding layer 221 on the substrate 210.

In this embodiment, the display panel 200 further includes a supporting layer 231, the supporting layer 231 is located on the pixel defining layer 230, in the manufacturing process of the display panel 200, usually, the light emitting layer 240 and the cathode 250 are manufactured by a vacuum evaporation process, the supporting layer 231 further plays a role of supporting a mask (mask), so as to prevent the mask from deforming, which causes uneven thickness of the light emitting layer 240 or the cathode 250, thereby easily forming a local strong electric field, causing generation of black spots in the OLED, affecting the display effect, and reducing the stability of the OLED display panel 200; moreover, the supporting layer 231 is usually made of a black gap material, i.e., has a light shielding effect, and also functions to separate different pixels of the OLED display panel 200 and prevent color mixing between adjacent pixels.

In addition, the orthographic projection of the supporting layer 231 on the substrate 210 is not overlapped with the orthographic projection of the first light shielding layer 221 on the substrate 210, because the supporting layer 231 is arranged on the pixel defining layer 230, and the first light shielding layer 221 is arranged below the pixel defining layer 230, the cross-sectional width of the supporting layer 231 is smaller than the cross-sectional width of the pixel defining layer 230, the supporting layer 231 is arranged in the middle of the pixel defining layer 230 and is not overlapped with the orthographic projection of the first light shielding layer 221, the aperture opening ratio between adjacent pixels is ensured, meanwhile, a certain manufacturing material of the supporting layer 231 can be saved, and certain production cost is reduced.

Meanwhile, the supporting layer 231 is usually made of a black matrix or a black gap material, and can prevent the color mixing of pixels between adjacent pixels. The cross-section of the support layer 231 may be trapezoidal, rectangular, or the like. Moreover, the number of the support layers 231 may be equal to or less than the number of the pixel defining layers 230, and preferably, the number of the support layers 231 may be less than the number of the pixel defining layers 230, and the support layers are uniformly disposed on different pixel defining layers 230 in the display panel 200, thereby ensuring that the light emission amount of the light emitting layer 240 is maximally utilized.

Further, the display panel 200 further includes an encapsulation layer 260 and a color filter layer 280, the encapsulation layer 260 is disposed on the cathode 250, and the color filter layer 280 is disposed on the encapsulation layer 260; the color filter layer 280 includes a light shielding portion 282 and a light filtering portion 281, the light shielding portion 282 is disposed corresponding to the pixel defining layer 230, a first color resist layer 225 and a second color resist layer 226 are stacked at the light shielding portion 282, and the first color resist layer 225 and the second color resist layer 226 have different colors; the light filter part 281 is disposed corresponding to the light emitting layer 240, and only one color resistance layer 224 is disposed at the light filter part 281, and the color of the color resistance layer 224 is the same as the color of the light emitting layer 240.

Because the OLED display panel 200 is extremely sensitive to water and oxygen, in this embodiment, an encapsulating layer 260 is further disposed above the cathode 250, and the encapsulating layer 260 is used for encapsulating the display panel 200, so that water and oxygen are effectively prevented, damage to the OLED display panel 200 can be avoided, and meanwhile, the encapsulating layer 260 also plays a role in insulating the cathode 250, and stability of the OLED display panel 200 is improved. In addition, the present application also adopts a COE technology (Color Filter On Encapsulation), that is, a technology of replacing a polarizing plate in the OLED display panel 200 with a Color Filter layer 280, where the Encapsulation layer 260 is provided with the Color Filter layer 280, the Color Filter layer 280 includes a light shielding portion 282 and a light filtering portion 281, the light shielding portion 282 is disposed corresponding to the pixel defining layer 230, and the light shielding portion 282 is formed by stacking two Color resist layers 224 with different colors, so as to achieve a light shielding effect, that is, the light shielding portion 282 is composed of a first Color resist layer 225 and a second Color resist layer 226; the light-filtering part 281 is disposed corresponding to the light-emitting layer 240, only one color-resisting layer 224 is disposed at the light-filtering part 281, and the color of the color-resisting layer 224 at the light-filtering part 281 is the same as the color of the light-emitting layer 240, so as to further filter light, improve color purity, and further improve the display effect of the display panel 200.

In the actual manufacturing process, the color resist layer 224 usually has three colors of red (R), green (G) and blue (B), therefore, the light shielding portion 282 may be composed of the color resist layer 224 of any two color combinations of R + G, R + B, G + B, and the light filtering portion 281 may be any one of R, G or B, so that, when manufacturing the color filter layer 280, the color resist layer 224 with the same color of the light shielding part 282 and the light filtering part 281 can share the same process, the color filter layer 280 can be formed by only using three R/G/B processes to complete the manufacture of the light shielding part 282 and the light filtering part 281, compared with the case that the light shielding part 282 is made of Black Matrix (BM), it needs to use four BM/R/G/B processes to form, so as to reduce one process, thereby reducing the production cost, improving the production efficiency and further expanding the productivity of the display panel 200.

Moreover, the color filter layer 280 replaces a commonly used polarizing plate, on one hand, the surface of the polarizing plate is usually a mirror surface, light reflection occurs, and the human eyes can be dazzled when watching, so that the visual experience of people is influenced, and the color filter layer 280 is made of the color filter layers 224 with different colors, so that part of the light of the environment can be filtered, the light reflection of the external environment is reduced, the human eyes are not dazzled when watching, and the visibility and the user experience are improved; on the other hand, the thickness of the polarizer is about 100 μm, and the thickness of the color resist layer 224 is only 1 μm to 2 μm, so that the color filter can be thinner than the polarizer, which is beneficial to the light design of the display panel 200, and further increases the market competitiveness of the product.

The second embodiment:

fig. 2 is a schematic view of a display panel according to a second embodiment of the present disclosure, and referring to fig. 2, it can be seen that, as a second embodiment of the present disclosure, unlike the first embodiment, the first light-shielding layer 221 further covers side surfaces of two adjacent anodes 220 facing each other.

In this embodiment, the first light shielding layer 221 covers not only the two ends of the anode 220 but also the opposite sides of the two adjacent anodes 220, so as to completely cover the two ends and the sides of the anode 220, and the first opening 223 for disposing the light emitting layer 240 is formed only in the middle of the anode 220, and the first light shielding layer 221 is made of a black photoresist material, so that not only the problem of light reflection at the two ends of the anode 220 can be prevented, but also the internal reflection phenomenon caused by the light irradiating the sides of the two adjacent anodes 220 through the pixel defining layer 230 can be prevented, and the display effect of the display panel 200 is better. In addition, the first light shielding layer 221 covers the opposite side surfaces of the two adjacent anodes 220, so that short circuit between the two adjacent anodes 220 can be prevented, and the stability of the display panel 200 is higher.

Example three:

fig. 3 is a schematic diagram of a third display panel according to a third embodiment of the present disclosure, and referring to fig. 3, as a third embodiment of the present disclosure, different from the second embodiment, the display panel 200 further includes a second light shielding layer 222, the second light shielding layer 222 is located between two adjacent anodes 220, and the second light shielding layer 222 is connected to the first light shielding layer 221 and is integrally formed.

In this embodiment, a second light-shielding layer 222 is further disposed between the pixel defining layer 230 and the substrate 210 and corresponding to a position between the adjacent anodes 220, and the second light-shielding layer 222 is connected to the first light-shielding layer 221 and integrally formed, so that the light-shielding layers are disposed below the pixel defining layer 230, and only the position of the light-emitting layer 240 is ensured to emit light, thereby preventing light reflection at two ends of the anode 220, preventing light inside the display panel 200 from passing through the pixel defining layer 230 and irradiating to the lower side of the substrate 210, reducing reflection of light inside the display panel 200, preventing color mixing between adjacent pixels, and increasing the utilization rate of light emitted by the light-emitting layer 240; moreover, the second light-shielding layer 222 can also shield the film layer below the substrate 210, such as metal lines, thin film transistors, etc., corresponding to the light-shielding portion 282 of the color filter layer 280, thereby achieving the dual light-shielding effect, and the display panel 200 has higher color purity and better display effect.

Moreover, the first light-shielding layer 221 and the second light-shielding layer 222 are integrally formed, are made of the same material, and are made of black gap materials, so that the stability and the light-shielding effect are better, a gap cannot be generated due to the fact that the first light-shielding layer 221 and the second light-shielding layer 222 are not connected, the problem that the light utilization rate of the gap is reduced due to internal reflection of light rays, even bright spots are generated at the gap is avoided, and the display effect of the display panel 200 is reduced; in addition, the first light-shielding layer 221 and the second light-shielding layer 222 can be manufactured by the same process, so that the production cost is reduced, and the production efficiency is improved.

Example four:

fig. 4 is a schematic diagram of a fourth display panel according to an embodiment of the present disclosure, and referring to fig. 4, it can be seen that, as a fourth embodiment of the present disclosure, the first light-shielding layer 221 is formed by stacking two color-resist layers 224 with different colors.

In this embodiment, the first light-shielding layer 221 is formed by stacking two color-resisting layers 224 with different colors, that is, the first light-shielding layer 221 is formed by stacking a first color-resisting layer 225 and a second color-resisting layer 226, so as to achieve the effect of shielding light at two ends of the anode 220; similarly, the first light-shielding layer 221 is further disposed between two adjacent anodes 220 in a covering manner, and the second light-shielding layer 222 is formed at the same time as the first opening 223 is formed only in the middle of the anode 220, thereby improving the light-shielding effect of the display panel 200.

Moreover, when the first light-shielding layer 221 is formed by stacking two color-resist layers 224, the pixel defining layer 230 can be made thinner, so that the light absorption rate of the pixel defining layer 230 can be further reduced, and the light utilization rate can be further improved. Certainly, when the first light-shielding layer 221 and the second light-shielding layer 222 are disposed and the color-resisting layers 224 stacked in two colors are used for forming, the colors of the two color-resisting layers 224 are different from the color of the light-emitting layer 240, and at this time, the pixel defining layer 230 may not be disposed, that is, the first light-shielding layer 221 and the second light-shielding layer 222 are made thicker, and replace the pixel defining layer 230, so that the two adjacent pixel regions are separated while the light is shielded, so as to implement the pixel array.

In this embodiment, the first light-shielding layer 221 is made of the first color resist layer 225, the pixel definition layer 230 is made of the second color resist layer 226, and the colors of the first color resist layer 225, the second color resist layer 226 and the light-emitting layer 240 are different, so that the pixel definition layer 230 and the first light-shielding layer 221 are overlapped to play a role in light-shielding, thereby preventing the light reflection at two ends of the anode 220, and the colors of the three are different, thereby preventing the pixel definition layer 230 and the first light-shielding layer 221 from absorbing light, and improving the utilization rate of light.

Similarly, the second light-shielding layer 222 is also made of the first color resist layer 225, and covers the area between the adjacent anodes 220, so that the pixel defining layer 230 and the second light-shielding layer 222 are overlapped to play a role in light shielding, so that light of the display panel 200 is not internally reflected, the film layer below the substrate 210 is completely shielded, and the display effect of the display panel 200 is better. Of course, the second light-shielding layer 222 can also be made of the third color-blocking layer 224, i.e. the color is different from that of the pixel defining layer 230 and the first light-shielding layer 221, and the light-shielding effect can also be achieved.

In addition, when the pixel defining layer 230 is made of the second color resist layer 226, the supporting layer 231 may also be made of the same material as the pixel defining layer 230, so that the supporting layer 231 and the pixel defining layer 230 may be integrally formed and formed by the same process, and the process of separately manufacturing the supporting layer 231 may be reduced, thereby reducing the production cost, and the supporting layer 231 and the pixel defining layer 230 are an integral structure, so that the stability of the display panel 200 is better.
