Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular, to a display module and a display device.

Background Art

[0002] In existing display devices, photosensitive elements (such as cameras) are usually integrated to enrich the functions of the display devices. At the same time, in order to increase the screen-to-body ratio of the display devices, the area of the light-emitting surface of the display device corresponding to the photosensitive element can also be used for display.

[0003] However, during display, the surface of the photosensitive element reflects light, resulting in a relatively high reflectivity in the area of the light-emitting surface of the display device corresponding to the photosensitive element, which affects the display quality.

[0040] Figure 1 A schematic diagram of a display module provided for the embodiments of this application. Figure 2 A schematic diagram of a display panel provided for the embodiments of this application. Figure 3 Another schematic diagram of a display panel provided for the embodiments of this application. Figure 4 A partial structural schematic diagram of a display module provided for the embodiments of this application during the first working period. Figure 5 is Figure 4 A partial structural schematic diagram of the display module shown during the second working period.

[0041] The embodiments of this application provide a display module 100, as Figure 1 shown, the display module 100 includes a display panel 01 and a photosensitive element 02. The photosensitive element 02 can be an electronic device such as a camera or an infrared identifier. The display panel 01 includes a main display area AA and a transmissive display area BB. The transmittance of the transmissive display area BB is greater than that of the main display area AA, and the main display area AA surrounds at least part of the transmissive display area BB.

[0042] Optionally, as Figure 2 shown, the transmissive display area BB is completely surrounded by the main display area AA.

[0043] Optionally, as shown in Figure 3 FIG. 1, the main display area AA surrounds the partially transmissive display area BB.

[0044] Wherein, along the thickness direction Z of the display module 100, the transmissive display area BB overlaps with the photosensitive element 02.

[0045] Specifically, along the thickness direction Z of the display module 100, the transmissive display area BB covers the photosensitive element 02.

[0046] It should be noted that in the embodiment of the present application, the transmissive display area BB is a transmissive display area in a macroscopic sense. Since the display panel 01 usually also includes light-blocking devices (such as metal traces, black matrices, etc.), and these light-blocking devices are usually also arranged in the transmissive display area BB, therefore, at the microscopic level, the transmissive display area BB may include light-blocking regions.

[0047] Combined with Figure 1 and Figure 4 、 Figure 5 FIG. 2, the transmissive display area BB includes an anti-reflection layer 10, and the anti-reflection layer 10 is used to control the amount of external light received by the photosensitive element 02.

[0048] Wherein, the display module 100 includes a first working period and a second working period. The photosensitive element 02 can be turned on in the first working period and turned off in the second working period. The anti-reflection layer 10 includes a plurality of anti-reflection structures 11, and the anti-reflection structures 11 are used to control the light transmittance of the anti-reflection layer 10 in the first working period to be greater than that in the second working period.

[0049] That is to say, in the first working period of the display module 100, the anti-reflection structure 11 can control a relatively large amount of external light to pass through the anti-reflection layer 10; in the second working period of the display module 100, the anti-reflection structure 11 can control a relatively small amount of external light to pass through the anti-reflection layer 10. The amount of light received by the photosensitive element 02 in the first working period of the display module 100 is greater than the amount of light received by it in the second working period of the display module 100.

[0050] Specifically, the number of external light rays blocked by the anti-reflection structure 11 during the first working period is less than the number of external light rays blocked by it during the second working period, thereby controlling the light transmittance of the anti-reflection layer 10 during the first working period to be greater than that during the second working period. Alternatively, the ability of the anti-reflection structure 11 to change the light path during the first working period is less than its ability to change the light path during the second working period, such that the number of light rays entering the photosensitive element 02 through the anti-reflection layer 10 during the first working period is greater than the number of light rays entering the photosensitive element 02 through the anti-reflection layer 10 during the second working period, thereby controlling the light transmittance of the anti-reflection layer 10 during the first working period to be greater than that during the second working period. Of course, in the display module 100 provided in the embodiment of the present application, it is possible to set that the number of light rays blocked by some of the anti-reflection structures 11 during the first working period is less than the number of light rays blocked by them during the second working period, and the ability of some of the anti-reflection structures 11 to change the light path during the first working period is less than their ability to change the light path during the second working period.

[0051] It can be understood that when the photosensitive element 02 is turned on, the transmissive display area BB in the display panel 01 cannot be displayed, and when the photosensitive element 02 is turned off, the transmissive display area BB can be displayed. That is to say, the transmissive display area BB cannot be displayed during the first working period of the display module 100, and can be displayed during the second working period of the display module 100.

[0052] In the prior art, in order to ensure the working effect of the photosensitive element 02, during the first working period of the display module 100, it is usually necessary to enable the photosensitive element 02 to receive a sufficient number of light rays. When the transmissive display area BB is being displayed, the more light rays the photosensitive element 02 receives, the more light rays it reflects, and these reflected light rays will exit through the transmissive display area BB, resulting in an increase in the reflectivity of the transmissive display area BB, affecting the display effect of the transmissive display area BB, and further affecting the display quality of the display panel 01.

[0053] In the embodiment of the present application, by setting the anti-reflection structure 11 to control the light transmittance of the anti-reflection layer 10 to be relatively large during the first working period of the display module 100, it is possible to ensure that the photosensitive element 02 receives a sufficient number of light rays during the first working period, thereby meeting the working requirements of the photosensitive element 02 and ensuring the working effect of the photosensitive element 02. At the same time, by setting the anti-reflection structure 11 to control the light transmittance of the anti-reflection layer 10 to be relatively small during the second working period of the display module 100, it is possible to reduce the number of light rays received by the photosensitive element 02 during the second working period, thereby reducing the number of light rays reflected by the photosensitive element 02, which is beneficial to reducing the reflectivity of the transmissive display area BB during the second working period, improving the display effect of the transmissive display area BB, and further being beneficial to improving the display quality of the display module 100.

[0054] In one embodiment of the present application, please continue to combine Figure 1and Figure 4 As shown in FIG. Figure 4 , the light-transmissive display area BB includes a plurality of light-transmissive areas B1 and a plurality of light-shielding areas B2. The light-transmissive areas B1 and the light-shielding areas B2 can be arranged alternately. External light can enter the anti-reflection layer 10 through the light-transmissive areas B1, and then enter the photosensitive element 02 through the anti-reflection layer 10.

[0055] Among them, the anti-reflection structure 11 can be used for light shielding. Combining Figure 4 and Figure 5 As shown in FIG. Figure 5 , the area of the anti-reflection structure 11 located in the light-transmissive area B1 in the first working period is smaller than the area of the anti-reflection structure 11 located in the light-transmissive area B1 in the second working period.

[0056] Specifically, the anti-reflection structure 11 is a non-transparent structure. Optionally, the anti-reflection structure 11 is black.

[0057] In the embodiment of the present application, it is set that the area of the anti-reflection structure 11 located in the light-transmissive area B1 in the first working period is smaller than the area of the anti-reflection structure 11 located in the light-transmissive area B1 in the second working period. Then, the number of external light rays blocked by the anti-reflection structure 11 in the first working period is less than the number of external light rays blocked by it in the second working period. That is, the number of external light rays passing through the anti-reflection layer in the first working period is more than the number of external light rays passing through the anti-reflection layer 10 in the second working period, so that the light transmittance of the anti-reflection layer 10 in the first working period is greater than that in the second working period, which is beneficial to ensuring that the photosensitive element 02 receives a larger number of light rays in the first working period to ensure the working effect of the photosensitive element 02; and the number of light rays received in the second working period is less to reduce the light transmittance of the light-transmissive display area BB in the second working period and improve the display effect.

[0058] In an implementation manner of the embodiment of the present application, as Figure 4 shown in FIG. Figure 4 , in the first working period, the anti-reflection structure 11 is located in the light-shielding area B2. That is, in the first working period, along the thickness direction Z of the display module 100, the anti-reflection structure 11 does not overlap with the light-transmissive area B1.

[0059] As Figure 5 shown in FIG. Figure 5 , in the second working period, along the thickness direction Z of the display module 100, the anti-reflection structure 11 at least partially overlaps with the light-transmissive area B1. That is, the anti-reflection structure 11 can extend to the light-transmissive area B1.

[0060] In this implementation manner, during the first working period, the anti-reflection structure 11 does not affect the external light from entering the photosensitive element 02 through the light-transmitting area B1, which is beneficial to ensuring that the photosensitive element 02 receives a sufficient amount of light to meet the working requirements of the photosensitive element 02. During the second working period, the anti-reflection structure 11 can block at least part of the external light irradiated on the anti-reflection layer 10, so that the light cannot pass through the anti-reflection layer 10 and be transmitted to the photosensitive element 02, thereby reducing the amount of light reflected by the photosensitive element 02, which is beneficial to reducing the reflectivity of the light-transmitting display area BB during the second working period and improving the display effect of the light-transmitting display area BB.

[0061] Preferably, during the second working period, along the thickness direction Z of the display module 100, the projection of the anti-reflection structure 11 covers the projection of the light-transmitting area B1. That is, the external light cannot enter the photosensitive element 02 through the anti-reflection layer 10. Thereby, it is possible to prevent the photosensitive element 02 from reflecting light to the light-transmitting display area BB during the second working period, which is beneficial to further ensuring the display effect of the light-transmitting display area BB.

[0062] In an embodiment of the present application, the anti-reflection structure 11 includes an electro-wetting material. During the first working period, the anti-reflection structure 11 is not powered on, and during the second working period, the anti-reflection structure 11 is powered on.

[0063] It can be known from the characteristics of the electro-wetting material that when the electro-wetting material is not powered on, the electro-wetting material is in a contracted state, and its contact surface with the lower-layer solid has a tendency to shrink into a spherical shape; when the electro-wetting material is powered on, the electro-wetting material is in an extended state, and its contact surface with the lower-layer solid has a tendency to expand. It can be understood that the larger the contact surface of the electro-wetting material with the lower-layer solid, the larger the area it occupies in the display panel 01, and the more external light it can block.

[0064] Optionally, the electro-wetting material is ink.

[0065] In the embodiment of the present application, during the first working period, the anti-reflection structure 11 is not powered on, which can make the anti-reflection structure 11 in a contracted state and occupy a smaller area in the display panel 01; during the second working period, the anti-reflection structure 11 is powered on, which can make the anti-reflection structure 11 in an extended state and occupy a larger area in the display panel 01. The embodiment of the present application can realize the conversion of the anti-reflection structure 11 between the contracted state and the extended state by whether the anti-reflection structure 11 is powered on, so as to realize that the area of the anti-reflection structure 11 located in the light-transmitting area B1 during the first working period is smaller than the area of the anti-reflection structure 11 located in the light-transmitting area B1 during the second working period.

[0066] Figure 6 It is a schematic diagram of a partial structure of another display module provided by the embodiment of the present application during the first working period. Figure 7 For Figure 6A partial structural schematic diagram of the display module shown during the second working period.

[0067] In an embodiment of the present application, in combination with Figure 1 and Figure 6 as shown, the light-transmitting display area BB includes a plurality of light-transmitting areas B1 and a plurality of light-blocking areas B2. The light-transmitting areas B1 and the light-blocking areas B2 can be arranged alternately. External light can enter the anti-reflection layer 10 through the light-transmitting areas B1, and then enter the photosensitive element 02 through the anti-reflection layer 10.

[0068] Along the thickness direction Z of the display module 100, the anti-reflection structure 11 at least partially overlaps with the light-transmitting area B1. That is, after external light enters the anti-reflection structure 11 in the anti-reflection layer 10 through the light-transmitting area B1, it is then transmitted into the photosensitive element 02.

[0069] Among them, the light transmittance of the anti-reflection structure 11 in the first working period is greater than that in the second working period.

[0070] Specifically, in combination with Figure 6 and Figure 7 as shown, the ability of the anti-reflection structure 11 to change the light path in the first working period is less than its ability to change the light path in the second working period, so that the number of external light rays entering the photosensitive element 02 after passing through the anti-reflection structure 11 in the first working period is greater than the number of external light rays entering the photosensitive element 02 after passing through the anti-reflection structure 11 in the second working period, thereby realizing that the light transmittance of the anti-reflection structure 11 in the first working period is greater than its light transmittance in the second working period.

[0071] For example, as Figure 6 shown, in the first working period, the ability of the anti-reflection structure 11 to change the light path is small, and external light can basically pass through the anti-reflection structure 11 in the incident direction and finally enter the photosensitive element 02. Thus, it is ensured that more external light can enter the photosensitive element 02, and further meet the working requirements of the photosensitive element 02.

[0072] As Figure 7 shown, in the second working period, the ability of the anti-reflection structure 11 to change the light path is large. The external light irradiated on the anti-reflection structure 11 is reflected and refracted by the anti-reflection structure 11, changing the outgoing direction of these external light rays, so that a large amount of external light irradiated on the anti-reflection structure 11 cannot enter the photosensitive element 02, resulting in a smaller number of light rays received by the photosensitive element 02 in the second working period.

[0073] In the embodiment of the present application, during the first working period, the light transmittance of the anti-reflection structure 11 is relatively large, so that more external light can enter the photosensitive element 02 through the anti-reflection structure 11, thereby ensuring the working effect of the photosensitive element 02 during the first working period. At the same time, during the second working period, the light transmittance of the anti-reflection structure 11 is relatively small, so that the amount of external light entering the photosensitive element 02 through the anti-reflection structure 11 is small, thereby reducing the amount of light reflected by the photosensitive element 02, which is conducive to reducing the reflectivity of the transmissive display area BB during the second working period and improving the display effect of the transmissive display area BB.

[0074] In one implementation manner of the embodiment of the present application, as Figure 6 and Figure 7 shown, the anti-reflection layer 10 includes a filling material 12, and the filling material surrounds at least part of the anti-reflection structure 11. That is, in the anti-reflection layer 10, the filling material 12 can cover the periphery of the anti-reflection structure 11. The filling material 12 can be a transparent structure.

[0075] During the first working period, the refractive index of the anti-reflection structure 11 is the same as that of the filling material 12, and during the second working period, the refractive index of the anti-reflection structure 11 is different from that of the filling material 12.

[0076] Specifically, the anti-reflection structure 11 includes an electro-optic refractive index variable material. The refractive index of the anti-reflection structure 11 can be adjusted by applying an electric current to the anti-reflection structure 11 to make it the same as or different from the refractive index of the surrounding filling material 12.

[0077] Optionally, the electro-optic refractive index variable material is one of lithium niobate, indium tin oxide, and potassium dihydrogen phosphate crystal.

[0078] It should be noted that in the embodiment of the present application, the fact that the refractive index of the anti-reflection structure 11 is the same as that of the filling material 12 means that the difference between the refractive index of the anti-reflection structure 11 and the refractive index of the filling material 12 is within a preset range; the fact that the refractive index of the anti-reflection structure 11 is different from that of the filling material 12 means that the difference between the refractive index of the anti-reflection structure 11 and the refractive index of the filling material 12 exceeds the aforementioned preset range. The preset range can be an error caused by process or material characteristics, etc., which makes it impossible for the refractive index of the anti-reflection structure 11 and the filling material 12 to be exactly the same.

[0079] In the embodiment of the present application, as Figure 6 shown, when the refractive index of the anti-reflection structure 11 is the same as that of the filling material 12, when external light irradiates the anti-reflection structure 11, refraction and reflection do not occur, and the external light can basically pass through the anti-reflection structure 11 in the incident direction and finally enter the photosensitive element 02, thereby ensuring that more external light can enter the photosensitive element 02 to meet the working requirements of the photosensitive element 02.

[0080] As Figure 7As shown, when the refractive index of the anti-reflection structure 11 is different from that of the filling material 12, the anti-reflection structure 11 becomes a microstructure that can change the optical path in the anti-reflection layer 10. When external light irradiates on the anti-reflection structure 11, a relatively large number of refracted and reflected light rays occur. These light rays are absorbed by the devices in the display module 100 after continuous reflection and refraction, so that a large amount of external light irradiating on the anti-reflection structure 11 cannot enter the photosensitive element 02. Moreover, even if it enters the photosensitive element 02, it will change the angle at which these light rays enter the photosensitive element 02, and further reflect and refract inside the display module 100, and it is difficult to be reflected to the light-transmitting display area BB for exit, thereby ensuring that the reflectivity of the light-transmitting display area BB is small during the second working period, which is beneficial to improving the display effect of the light-transmitting display area BB.

[0081] Figure 8 It is a schematic diagram of a partial structure of a display module provided by an embodiment of the present application.

[0082] In an embodiment of the present application, as Figure 8 shown, the anti-reflection layer 10 further includes a light-absorbing structure 13, and the light-absorbing structure 13 is located between two adjacent anti-reflection structures 11. Of course, the light-absorbing structure 13 is also located in the light-shielding area B2 at the same time.

[0083] Optionally, a light-absorbing structure 13 is provided between any two adjacent anti-reflection structures 11.

[0084] In the embodiment of the present application, when the light-absorbing structure 13 is provided between two adjacent anti-reflection structures 11, during the second working period of the display module 100, the light rays reflected and refracted by the anti-reflection structure 11 are easily irradiated on the light-absorbing structure 13 and thus absorbed by the light-absorbing structure 13. Moreover, the light rays reflected after entering the photosensitive element 02 are also easily absorbed by the light-absorbing structure 13, which is beneficial to further reducing the reflectivity of the light-transmitting display area BB, and thus beneficial to further improving the display effect of the light-transmitting display area BB.

[0085] In addition, during the first working period of the display module 100, external light can basically pass through the anti-reflection structure 11 in the incident direction and finally enter the photosensitive element 02. The setting of the light-absorbing structure 13 does not affect the transmission of external light during the first working period.

[0086] In an embodiment of the present application, please continue to refer to Figures 6 - 8 , the anti-reflection structure 11 includes a first inclined surface 11A, and the first inclined surface 11A is used to receive external light. That is, when external light irradiates on the anti-reflection structure 11 through the light-transmitting area B1, at least part of the external light can irradiate on the first inclined surface 11A.

[0087] Optionally, the first inclined surface 11A is the surface of the anti-reflection structure 11 facing the light-emitting surface of the display panel 01.

[0088] In the embodiment of the present application, the anti-reflection structure 11 includes a first inclined surface 11A for receiving external light. Then, in the second working period, the external light irradiated into the anti-reflection structure 11 along the thickness direction Z of the display module 100 can be reflected and refracted and then transmitted to the periphery of the anti-reflection structure 11, rather than being transmitted along the thickness direction Z of the display module 100, which is beneficial to ensuring that the transmission path of the external light is changed in the second working period.

[0089] It should be noted that in the embodiment of the present application, the first inclined surface 11A is inclined with respect to the plane where the display panel 01 is located.

[0090] Figure 9 It is a schematic diagram of a partial structure of another display module provided by the embodiment of the present application.

[0091] In an embodiment of the present application, at least part of the first inclined surfaces 11A have the same inclination direction.

[0092] That is to say, in the display module 100, the inclination directions of the first inclined surfaces 11A in all the anti-reflection structures 11 can be set to be the same, or the inclination directions of the first inclined surfaces 11A in some of the anti-reflection structures 11 can be set to be the same and different from the inclination directions of the first inclined surfaces 11A in another part of the anti-reflection structures 11.

[0093] For example, as Figure 8 and Figure 9 shown, in the display module 100, the first inclined surface 11A in the anti-reflection structure 11 includes a first end 11A1 and a second end 11A2. Along the thickness direction Z of the display module, the distance between the second end 11A2 and the light-emitting surface of the display panel 01 is less than the distance between the first end 11A1 and the light-emitting surface of the display panel 01. A plurality of anti-reflection structures 11 are arranged along the first direction X, and the first direction X intersects with the thickness direction Z of the display module 100.

[0094] Optionally, as Figure 8 shown, along the first direction X, among the first inclined surfaces 11A of all the anti-reflection structures 11, the second ends 11A2 are all located on the same side of their corresponding first ends 11A1. That is, the inclination directions of the first inclined surfaces 11A in all the anti-reflection structures 11 are the same.

[0095] Optionally, as Figure 9As shown, among the multiple anti-reflection structures 11, there are a first type of anti-reflection structure 110 and a second type of anti-reflection structure 111. Along the first direction X, among the first inclined surfaces 11A of all the first type of anti-reflection structures 110, the second ends 11A2 are all on the same side of their corresponding first ends 11A1, that is, the inclination directions of the first inclined surfaces 11A in all the first type of anti-reflection structures 110 are the same; among the first inclined surfaces 11A of all the second type of anti-reflection structures 111, the second ends 11A2 are all on the same side of their corresponding first ends 11A1, that is, the inclination directions of the first inclined surfaces 11A in all the second type of anti-reflection structures 111 are the same; and the second ends 11A2 of the first type of anti-reflection structures 110 and the second ends 11A2 of the second type of anti-reflection structures 111 are respectively on different sides of their corresponding first ends 11A1, that is, the inclination directions of the first inclined surfaces 11A in the first type of anti-reflection structures 110 and the second type of anti-reflection structures 111 are different.

[0096] The embodiment of the present application is beneficial to simplifying the design of the anti-reflection structure 11 and saving the manufacturing cost of the display module 100.

[0097] Figure 10 It is a partial structural schematic diagram of another display module provided by the embodiment of the present application. Figure 11 It is a partial structural schematic diagram of another display module provided by the embodiment of the present application.

[0098] In an embodiment of the present application, as Figure 10 and Figure 11 shown, the anti-reflection structure 11 may further include a second inclined surface 11B. The inclination direction of the second inclined surface 11B is different from that of the first inclined surface 11A, and the second inclined surface 11B can also be used to receive external light. That is, when the external light irradiates the anti-reflection structure 11 through the light-transmitting area B1, at least part of the external light can irradiate on the second inclined surface 11B.

[0099] Optionally, as Figure 10 shown, the section of the anti-reflection structure 11 along the thickness direction Z of the display module 100 is triangular, or as Figure 11 shown, the section of the anti-reflection structure 11 along the thickness direction Z of the display module 100 is trapezoidal.

[0100] In the embodiment of the present application, since the inclination direction of the second inclined surface 11B is different from that of the first inclined surface 11A, the direction of the light reflected by the second inclined surface 11B can be different from the direction of the light reflected by the first inclined surface 11A, which is beneficial to further improving the ability of the anti-reflection structure 11 to change the light path, reflecting more of the external light irradiated on the anti-reflection structure 11 to the periphery of the anti-reflection structure 11, and then being absorbed by the components in the display module 100, so as to be beneficial to further reducing the reflectivity of the light-transmitting display area BB and improving the display effect of the light-transmitting display area BB.

[0101] Figure 12 Schematic diagram of a display device provided by an embodiment of the present application.

[0102] An embodiment of the present application provides a display device 200, and the display device 200 includes a display module 100 provided as in the above embodiment. The display device 200 provided by the embodiment of the present application may be an electronic device such as a mobile phone, a computer, a television, and an in-vehicle display device, etc., and the embodiment of the present application does not make specific limitations.

[0103] In the display device 200, a light reduction structure 11 is provided to control the light transmittance of the light reduction layer 10 to be relatively large during the first working period of the display module 100, so as to ensure that the photosensitive element 02 receives a sufficient amount of light during the first working period, thereby meeting the working requirements of the photosensitive element 02 and ensuring the working effect of the photosensitive element 02. At the same time, the light reduction structure 11 is provided to control the light transmittance of the light reduction layer 10 to be relatively small during the second working period of the display module 100, so as to reduce the amount of light received by the photosensitive element 02 during the second working period, thereby reducing the amount of light reflected by the photosensitive element 02, which is beneficial to reducing the reflectivity of the transmissive display area BB during the second working period, improving the display effect of the transmissive display area BB, and further beneficial to improving the display quality of the display module 100.

[0104] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
