[0048] In some embodiments, the light-emitting device layer is disposed on the array substrate, specifically, it can be disposed on the second flat layer, and the light-emitting device layer may include an anode layer, a pixel definition layer, a light-emitting layer 10, and a cathode layer; wherein, the anode layer includes a plurality of anodes disposed on the array substrate, pixel openings corresponding to the plurality of anodes are formed in the pixel definition layer, and each pixel opening exposes the surface of the corresponding anode away from the array substrate side.

[0049] It should be noted that the display module includes a display area 101, and the display area 101 may include a plurality of pixel areas 1011 and sensors 1012 adjacent to the pixel areas 1011; and the plurality of anodes are correspondingly located within the plurality of pixel areas 1011. Similarly, the plurality of pixel openings are also formed within the plurality of pixel areas 1011; for example, one anode and one pixel opening are provided in each pixel area 1011.

[0050] The light-emitting layer 10 includes a plurality of light-emitting portions 11 disposed within the plurality of pixel openings, and each light-emitting portion 11 is disposed within the corresponding pixel opening and on the corresponding anode, that is, the plurality of light-emitting portions 11 can be correspondingly disposed within the plurality of pixel areas 1011 one by one.

[0051] The cathode layer covers the pixel definition layer and the plurality of light-emitting portions 11; wherein, the anode is used to provide holes for injection, and the cathode layer is used to inject electrons. The holes and electrons recombine in the light-emitting portion 11 to excite light, so as to realize the light-emitting function of the display module.

[0052] The display module further includes a packaging layer 40 disposed on the side of the light-emitting device layer away from the array substrate, and the packaging layer 40 can cover the side of the cathode layer away from the light-emitting layer 10; it can be understood that in the drawings provided by the embodiments of the present application, the film layers other than the light-emitting layer 10 in the light-emitting device layer are not shown, and only one light-emitting portion 11 is shown to illustrate the positional correspondence relationship between the light-emitting portion 11 and the subsequent film layers.

[0053] In some embodiments, the packaging layer 40 includes a first inorganic sub-layer 41, an organic sub-layer 42, and a second inorganic sub-layer 43 stacked, and the organic sub-layer 42 is located between the first inorganic sub-layer 41 and the second inorganic sub-layer 43, and the first inorganic sub-layer 41 is located between the light-emitting layer 10 and the organic sub-layer 42.

[0054] In some embodiments, the display module may further include a touch layer, and the touch layer can be disposed on the side of the second inorganic sub-layer 43 away from the organic sub-layer 42.

[0055] In the embodiments of the present application, the display module further includes a color filter layer 20, and the color filter layer 20 is disposed on the light-emitting side of the light-emitting layer 10, specifically, it can be disposed on the side of the packaging layer 40 away from the light-emitting layer 10; further, the color filter layer 20 can be disposed on the side of the touch layer away from the packaging layer 40.

[0056] The color film layer 20 includes a plurality of light filtering portions 21 disposed in a plurality of pixel regions 1011 and a light shielding portion 22 disposed between adjacent light filtering portions 21; wherein, the plurality of light filtering portions 21 can be correspondingly disposed with the plurality of light emitting portions 11, and the color of the light filtering portion 21 corresponding to each light emitting portion 11 is the same as the light emitting color of the light emitting portion 11, while the light shielding portion 22 can block the light from passing through. Therefore, the color film layer 20 in the embodiment of the present application can transmit the light emitted by the light emitting portion 11, and at the same time, can also play a role in anti-reflection and improving the display effect of the display module.

[0057] In the embodiment of the present application, the color film layer 20 includes a first opening 220 formed in the sensing region 1012; it can be understood that the light filtering portion 21 is located in the pixel region 1011, while the light shielding portion 22 is located in other regions outside the pixel region 1011 and includes the sensing region 1012, that is, the light shielding portion 22 will cover the sensing region 1012; and the first opening 220 is formed in the sensing region 1012. Therefore, the first opening 220 is formed in the light shielding portion 22, so that the light can pass through the first opening 220 and pass through the sensing region 1012, improving the light incident amount and transmittance in the sensing region 1012.

[0058] As Figure 2 shown, the first opening 220 is formed outside the pixel region 1011; the first opening 220 can be formed between adjacent light emitting portions 11 and does not overlap with the light emitting portion 11 in the thickness direction of the display module.

[0059] In some embodiments, the display module further includes a sensor 50, and the sensor 50 is correspondingly disposed with at least one first opening 220, that is, the sensor 50 is correspondingly disposed with the sensing region 1012. In the embodiment of the present application, by providing the first opening 220, the light incident amount and transmittance of the sensing region 1012 can be increased, and thus the light incident amount of the sensor 50 can be increased, effectively improving the sensing effect of the sensor 50.

[0060] In some embodiments, the sensor 50 may include a camera, an infrared sensor, etc.

[0061] It should be noted that, please refer to Figure 3 and Figure 4, in the embodiment of the present application, the sensor 50 is disposed within the display area 101. However, the specific position of the sensor 50 within the display area 101 can be selected according to actual requirements. For example, the display area 101 may include a conventional display area 1013 and a sensing display area 1014. Among them, the sensor 50 can be disposed within the sensing display area 1014. Furthermore, in the present application, the first opening 220 is formed within the sensing display area 1014, and the sensing display area 1014 can be divided into multiple pixel areas 1011 and sensing areas 1012 located between adjacent pixel areas 1011; at least one first opening 220 can be provided in the sensing display area 1014, or multiple first openings 220 can be provided according to the transmittance requirement. In addition, the conventional display area 1013 contains multiple pixel areas 1011 and does not provide the first opening 220.

[0062] In some embodiments, the display area 101 may contain multiple sensing display areas 1014, and the sensing display areas 1014 can be distributed at any position within the display area 101, which is not limited herein.

[0063] In the embodiment of the present application, the display module further includes a first refractive index layer 31 and a second refractive index layer 32 disposed on the side of the color filter layer 20 away from the light-emitting layer 10. The first refractive index layer 31 covers the light-shielding portion 22 and the light-filtering portion 21. A groove 310 is formed in the first refractive index layer 31 and is disposed in alignment with the first opening 220 in the thickness direction of the display module. The second refractive index layer 32 is at least disposed on the inner wall of the groove 310, and the refractive index of the second refractive index layer 32 is greater than that of the first refractive index layer 31; thus, a microlens structure can be formed on the side of the first opening 220 away from the light-emitting layer 10, which can converge the light.

[0064] Among them, the inner wall of the groove 310 can be regarded as the side wall plus the bottom surface of the groove 310, that is, the second refractive index layer 32 at least covers the side wall and the bottom surface of the groove 310.

[0065] Please continue to refer to Figure 3 , when the first light a enters the groove 310, when the first light a passes through the interface between the first refractive index layer 31 and the second refractive index layer 32, refraction will occur, causing the first light a to emit towards the center direction of the groove 310; and a second light b is formed, and the second light b can pass through the first opening 220 and finally reach the sensor 50; therefore, in the embodiment of the present application, the microlens structure formed by the first refractive index layer 31 and the second refractive index layer 32 at the groove 310 can form a light-concentrating effect, causing the first light a that would originally be blocked by the light-shielding portion 22 to be refracted into the second light b and can pass through the first opening 220 to reach the sensor 50, so as to increase the light incident amount and transmittance of the display module and improve the photosensitive effect of the sensor 50.

[0066] It should be noted that since a groove 310 is formed above the first opening 220 in the embodiment of the present application, which can play a role in condensing light. Therefore, on the basis of maintaining the same light incident amount and transmittance, the present application can reduce the opening area of the first opening 220 to further reduce the reflection of the display module and further improve the contrast and display effect of the display module.

[0067] In some embodiments, a groove 310 is formed on the side of the first refractive index layer 31 away from the color filter layer 20, and the depth of the groove 310 is less than the thickness of the first refractive index layer.

[0068] In some embodiments, the second refractive index layer 32 is disposed on the side of the first refractive index layer 31 away from the color filter layer 20. The groove 31 is filled on the side of the second refractive index layer 32 close to the first refractive index layer 31, and the side of the second refractive index layer 32 away from the first refractive index layer 31 is a flat surface; on the one hand, it provides a flat film surface for subsequent processes, and on the other hand, it avoids the influence of the concave-convex structure on the light incident and light output effects.

[0069] In some embodiments, the width of the groove 310 on the side close to the color filter layer 20 is less than the width of the groove 310 on the side away from the color filter layer 20, so that the groove 310 is formed into a groove with a wider upper part and a narrower lower part, which is conducive to converging light. In some embodiments, the inner wall of the groove 310 can be an arc surface.

[0070] In some embodiments, the orthographic projection of the first opening 220 on the second refractive index layer 32 is located within the orthographic projection of the groove 310 on the second refractive index layer 32; more light can pass through the groove 310 to produce a light condensing effect, further increasing the light incident amount of the first opening 220 and improving the photosensitive effect of the sensor 50.

[0071] In some embodiments, the refractive index of the first refractive index layer 31 can be greater than or equal to 1.4 and less than or equal to 1.6, and the refractive index of the second refractive index layer 32 can be greater than or equal to 1.5 and less than or equal to 2; the difference between the refractive index of the second refractive index layer 32 and the refractive index of the first refractive index layer 31 needs to be greater than or equal to 0.1 so that there is a sufficient refractive index difference between the first refractive index layer 31 and the second refractive index layer 32 to form an effective light condensation.

[0072] In some embodiments, the material of the first refractive index layer 31 and the material of the second refractive index layer 32 are each independently selected from at least one of acrylic system materials, acrylic-siloxane hybrid system materials, and siloxane system materials; and the second refractive index layer 32 can also be doped with refractive particles, such as at least one of silicon oxide, aluminum oxide, and titanium oxide.

[0073] In some embodiments, please refer to Figure 5, the first refractive index layer 31 fills the first opening 220 on the side close to the color filter layer 20, and the refractive index of the first refractive index layer 31 is less than or equal to the refractive index of the light-shielding portion 22, thereby further enhancing the converging effect and improving the photosensitive effect of the sensor 50.

[0074] In a specific embodiment of the present application, please refer to Figure 1 , the light-shielding portion 22 includes a black matrix, and a plurality of second openings 210 located in the pixel region 1011 and a first opening 220 located in the sensing region 1012 are formed in the black matrix. The plurality of second openings 210 are correspondingly arranged with the plurality of color filter portions 21, and the color filter portions 21 are at least arranged in the corresponding second openings 210.

[0077] In another specific embodiment of the present application, please refer to Figure 6 , the color filter layer 20 includes a plurality of first color resistor blocks 23, a plurality of second color resistor blocks 24, and a plurality of third color resistor blocks 25. The colors of the first color resistor block 23, the second color resistor block 24, and the third color resistor block 25 are different from each other. The color filter layer 20 includes a plurality of color filter sub-regions 201 correspondingly arranged with the plurality of light-emitting portions 11 and a light-shielding sub-region 202 located between adjacent color filter sub-regions 201.

[0078] Each color filter portion 21 includes any one of the first color resistor block 23, the second color resistor block 24, and the third color resistor block 25 arranged in the color filter sub-region 201, and the light-shielding portion 22 includes at least two of the first color resistor block 23, the second color resistor block 24, and the third color resistor block 25 stacked in the light-shielding sub-region 202; for example, the first color resistor block 23, the second color resistor block 24, and the third color resistor block 25 are stacked in the light-shielding sub-region 202, thereby blocking light from passing through the light-shielding sub-region 202, and the first opening 220 penetrates through the stacked first color resistor block 23, second color resistor block 24, and third color resistor block 25.

[0079] Among them, the first color resistance block 23, the second color resistance block 24, and the third color resistance block 25 are selected as one of a red color resistance block, a green color resistance block, and a blue color resistance block, and the colors of the first color resistance block 23, the second color resistance block 24, and the third color resistance block 25 are different from each other.

[0080] It can be understood that in the manufacturing process of the display module, the preparation sequence of the color film layer 20 can be the red color resistance block, the green color resistance block, and the blue color resistance block in sequence; among them, the preparation sequences of the red color resistance block, the green color resistance block, and the blue color resistance block can be interchanged.

[0081] In another specific embodiment of the present application, please refer to Figure 7 , the color film layer 20 includes a plurality of first color resistance blocks 23, a plurality of second color resistance blocks 24, and a plurality of third color resistance blocks 25. The colors of the first color resistance block 23, the second color resistance block 24, and the third color resistance block 25 are different from each other. The color film layer 20 includes a plurality of filter sub-regions 201 corresponding to the plurality of light emitting portions 11 and light shielding sub-regions 202 located between adjacent filter sub-regions 201.

[0082] Each filter portion 21 includes any one of the first color resistance block 23, the second color resistance block 24, and the third color resistance block 25 disposed in the filter sub-region 201, and the light shielding portion 22 includes at least two of the first color resistance block 23, the second color resistance block 24, and the third color resistance block 25 stacked in the light shielding sub-region 202; for example, the first color resistance block 23 and the second color resistance block 24 are stacked in the light shielding sub-region 202, so that light can be blocked from passing through the light shielding sub-region 202, and the first opening 220 penetrates through the stacked first color resistance block 23 and second color resistance block 24.

[0083] It can be understood that the first color resistance block 23 and the third color resistance block 25 can also be stacked in the light shielding sub-region 202, or the second color resistance block 24 and the third color resistance block 25 can be stacked.

[0084] Among them, the first color resistance block 23, the second color resistance block 24, and the third color resistance block 25 are selected as one of a red color resistance block, a green color resistance block, and a blue color resistance block, and the colors of the first color resistance block 23, the second color resistance block 24, and the third color resistance block 25 are different from each other. For example, the first color resistance block 23 can be a red color resistance block, the second color resistance block 24 can be a green color resistance block, and the third color resistance block 25 can be a blue color resistance block; or the colors of the three can be interchanged.

[0085] It can be understood that in the manufacturing process of the display module, the preparation sequence of the color filter layer 20 can be the red color resist block, the green color resist block, and the blue color resist block in sequence; among them, the preparation sequences of the red color resist block, the green color resist block, and the blue color resist block can be interchanged.

[0086] In summary, in the embodiment of the present application, by forming the first opening 220 in the color filter layer 20 within the sensing area 1012, the transmittance of the sensing area 1012 can be effectively improved; at the same time, in the first refractive index layer 31, a groove 310 is formed opposite to the first opening 220, and the second refractive index layer 32 with a refractive index greater than that of the first refractive index layer 31 is at least disposed on the inner wall of the groove 310. Thus, a microlens structure opposite to the first opening 220 can be formed in the sensing area 1012 to converge the incident light, increasing the amount of light entering the first opening 220, effectively improving the incident light amount in the sensing area of the display module, and further improving the transmittance of the sensing area 1012; furthermore, the incident light amount of the sensor located in the sensing area 1012 can be effectively increased, improving the sensing effect of the sensor.
