Description

Technical Field

[0001] The present application belongs to the technical field of display panels, and in particular to a display panel and a display device. Background Art

[0002] With the development of the display panel field, gesture control of display panels has become more and more common in people's daily lives. The so-called gesture control refers to the display panel performing corresponding operations according to the user's gestures, which requires the recognition of the user's gestures. At present, a light sensor is usually set on the display panel. The infrared light emitted by the infrared light source is reflected by the user's finger and received by the light sensor, so that the user's gesture is recognized according to the received reflected light.

[0003] However, when the light sensor receives the reflected light, the reflected light tends to diverge after being reflected by the finger, so the light intensity shining on the light sensor is attenuated, resulting in a decrease in the sensing amount, affecting the accuracy of gesture recognition.

[0029] In practical applications, gesture control of display devices has become increasingly common in people's daily lives. The so-called gesture control refers to the display device performing corresponding operations according to the user's gesture (that is, the user's hand movement). For example, in a fruit-cutting game, the user can use his hand to make upward, downward and other movements in the air in the area of ​​the display panel. After recognizing the user's gesture, the display device can generate blade image information in the same direction as the gesture based on the user's gesture, and display the blade on the display panel based on the blade image information.

[0030] The display device can usually realize gesture recognition by receiving infrared light reflected by the user's finger according to the light sensor in the display panel. The embodiment of the present application provides a display panel and a display device, which can improve the accuracy of gesture recognition by improving the utilization rate of infrared light and increasing the sensing amount. In order to illustrate the technical solution described in the present application, the following is a detailed description in conjunction with specific drawings and embodiments.

[0031] See also Figure 1 , Figure 1 A schematic diagram of a cross-sectional structure of a display panel provided in an embodiment of the present application is shown. In the embodiment of the present application, the display panel 2 may include a color filter substrate 21 and an array substrate 22 that are relatively arranged; a liquid crystal layer 23 is arranged between the color filter substrate 21 and the array substrate 22; wherein a reflective layer 24 is arranged on the surface of the color filter substrate 21 on the side close to the liquid crystal layer 23; and a sensing layer 25 is arranged on the surface of the array substrate 22 on the side close to the liquid crystal layer 23.

[0032] like Figure 1 As shown, the display panel 2 may include a stacked color filter substrate 21, a reflective layer 24, a liquid crystal layer 23, a sensing layer 25 and an array substrate 22. When the display panel 2 is in use, an infrared light source for emitting infrared light may be provided on the side or below the display panel 2.

[0033] The user can make relevant gestures in the air at a position far away from the display panel 2, and the infrared light emitted by the infrared light source will irradiate the user's fingers. The infrared light reflected by the user's fingers will pass through the liquid crystal layer 23 and irradiate the sensing layer 25. Due to the scattering of infrared light, the infrared light will be attenuated and dissipated during propagation. In other words, the infrared light reflected by the user's fingers will be reflected and scattered after passing through the liquid crystal layer 23. Some of the infrared light can be received by the sensing layer 25 for identifying the user's gestures. However, another part of the infrared light not received by the sensing layer 25 will be reflected back again. Because it is not received by the sensing layer 25, this part of the infrared light is invalid sensing light and often cannot be used for gesture recognition. At this time, by setting a reflective layer 24 on the surface of the color film substrate 21 on the side close to the liquid crystal layer 23, this part of the infrared light not received by the sensing layer 25 is reflected back and irradiated on the reflective layer 24, and then reflected back to the sensing layer 25 through the reflective layer 24, and can be received by the sensing layer 25.

[0034] In the embodiment of the present application, the infrared light that is not received by the sensing layer 25 can be reflected by the reflective layer 24 and then reused, which effectively improves the utilization rate of the infrared light and increases the sensing amount of the sensing layer 25, thereby improving the accuracy of gesture recognition. In addition, since the display panel 2 provided in the embodiment of the present application can increase the sensing amount of the sensing layer 25 and improve the signal strength, the light source intensity requirement for the infrared light source can be reduced while ensuring that the sensing layer 25 has a sufficiently high sensing amount. In other words, the current of the infrared light source can be reduced, thereby effectively reducing power consumption.

[0035] It is understandable that the reflective layer 24 of the embodiment of the present application can be made of opaque metal materials, or can be made of other composite materials with high reflectivity to infrared light, which is not specifically limited here.

[0036] See also Figure 2 and Figure 3 In some embodiments, the color film substrate 21 includes a plurality of color resist blocks 212, and a black matrix 213 is disposed between two adjacent color resist blocks 212; the reflective layer 24 is disposed on a surface of the black matrix 213 on a side close to the liquid crystal layer 23, and a projection of the reflective layer 24 in a direction perpendicular to the display panel 2 is located within a projection of the black matrix 213 in a direction perpendicular to the display panel 2.

[0037] like Figure 2 As shown, the color filter substrate 21 may include a substrate 211, a plurality of color resist blocks 212 and a black matrix 213. The plurality of color resist blocks 212 may be arranged at intervals on a side of the substrate 211 close to the liquid crystal layer 23, and each color resist block 212 may be used to transmit a single color light. For example, the plurality of color resist blocks 212 may include red color resist blocks, green color resist blocks and blue color resist blocks that are alternately arranged, wherein the red color resist blocks can transmit red light, the green color resist blocks can transmit green light, and the blue color resist blocks can transmit blue light. It is understandable that the color resist blocks 212 may also transmit infrared light.

[0038] The black matrix 213 can be disposed between two adjacent color-resistance blocks 212, which can effectively prevent light leakage and color mixing between the color-resistance blocks 212, increase color contrast, and significantly reduce light pollution caused by interference between light spots, presenting a more stable and clear image quality to ensure the display effect of the display panel 2. The black matrix 213 can be a metal oxide film or a resin-type black photoresist film such as carbon black, as long as it can play a light-shielding effect, and is not specifically limited here.

[0039] The reflective layer 24 may be disposed on a surface of the black matrix 213 on a side close to the liquid crystal layer 23, and a projection of the reflective layer 24 in a direction perpendicular to the display panel 2 may be located within a projection of the black matrix 213 in a direction perpendicular to the display panel 2. In other words, the coverage area of ​​the reflective layer 24 may be less than or equal to the coverage area of ​​the black matrix 213, and the reflective layer 24 may be disposed at a corresponding position of the black matrix 213.

[0040] It is understandable that a backlight module can also be set under the display panel 2, and the backlight module can emit white visible light, which irradiates the color filter substrate 21, and then transmits the monochromatic light from the color block 212, so that the human eye can receive saturated light of a certain color. At the same time, the infrared light source 1 emits infrared light, and the infrared light reflected by the user's finger passes through the color block 212, passes through the liquid crystal layer 23, and then irradiates the sensing layer 25. The reflective layer 24 is set at the corresponding position of the black matrix 213, which can improve the phenomenon that the monochromatic light or infrared light is reflected back by the reflective layer 24 when passing through the color block 212, and to a certain extent, it can prevent the transmittance of the monochromatic light or infrared light from being affected by the setting of the reflective layer 24, thereby effectively ensuring the display effect of the display panel 2 and the effect of gesture recognition.

[0041] like Figure 3 As shown, the infrared light source 1 can be arranged on one side of the display panel 2, and the infrared light source 1 is used to emit infrared light. After the infrared light reflected by the user's finger passes through the liquid crystal layer 23, part of the infrared light is irradiated on the sensing layer 25 and received by the sensing layer 25; part of the infrared light is irradiated on the sensing layer 25 but not received by the sensing layer 25, but reflected back by the sensing layer 25; and part of the infrared light is not irradiated on the sensing layer 25, but reflected back by the array substrate 22. At this time, the infrared light that is not received by the sensing layer 25 can be irradiated on the reflective layer 24 after reflection, and is reflected back to the sensing layer 25 again through the reflective layer 24, and can then be received by the sensing layer 25. In this way, the utilization rate of infrared light is effectively improved, the sensing amount of the sensing layer 25 is increased, thereby improving the accuracy of gesture recognition and reducing power consumption.

[0042] See also Figure 4 In some embodiments, the projection of the reflective layer 24 and the black matrix 213 in a direction perpendicular to the display panel 2 coincides.

[0043] like Figure 4As shown, in the direction perpendicular to the display panel 2, the projection of the reflective layer 24 can overlap with the projection of the black matrix 213. For example, the reflective layer 24 can be set at the corresponding position of the black matrix 213, and the pattern shape of the reflective layer 24 can completely match the pattern shape of the black matrix 213. On the one hand, as described above, this can improve the phenomenon that the monochromatic light or infrared light is reflected back by the reflective layer 24 when passing through the color block 212, and to a certain extent, it can prevent the transmittance of the monochromatic light or infrared light from being affected by the setting of the reflective layer 24, thereby effectively ensuring the display effect of the display panel 2 and the effect of gesture recognition. On the other hand, because the pattern shape of the reflective layer 24 completely matches the pattern shape of the black matrix 213, in this way, in the manufacturing process of the display panel 2, the preparation of the reflective layer 24 and the preparation of the black matrix 213 can share a photomask. In other words, it avoids increasing the cost of a photomask, and can effectively reduce the manufacturing cost of the display panel 2.

[0044] See also Figure 5 In some embodiments, the reflective layer 24 includes a plurality of reflective blocks 241 corresponding to the plurality of black matrices 213, the reflective blocks 241 include a first surface facing away from the black matrix 213 and a second surface close to the black matrix 213, and a projection of the first surface in a direction perpendicular to the display panel is smaller than a projection of the second surface in a direction perpendicular to the display panel.

[0045] It can be understood that a reflective layer 24 is set on the surface of the black matrix 213 on the side close to the liquid crystal layer 23. The reflective layer 24 generally has a certain thickness. When the monochromatic light or infrared light passes through the color block 212, it may irradiate the side of the reflective layer 24 and then be reflected back by the side of the reflective layer 24, thereby affecting the transmittance of the monochromatic light or infrared light to a certain extent.

[0046] In order to solve the above problems, Figure 5 As shown, in the embodiment of the present application, the reflective layer 24 may include a plurality of reflective blocks 241 corresponding to the plurality of black matrices 213, and the reflective blocks 241 include a first surface and a second surface, wherein the first surface is away from the black matrix 213, the second surface is close to the black matrix 213, and the projection of the first surface may be smaller than the projection of the second surface in a direction perpendicular to the display panel 2. In other words, in a cross section perpendicular to the direction of the display panel 2, the cross section of the reflective block 241 may be a trapezoid, and the long side of the trapezoid may be close to the black matrix 213, and the short side of the trapezoid may be close to the liquid crystal layer 23.

[0047] In this way, the side of each reflection block 241 has a certain slope. When the monochromatic light or infrared light passes through the color blocking block 212, the probability of irradiating the side of the reflection block 241 can be reduced, thereby improving the phenomenon that the monochromatic light or infrared light is reflected back by the side of the reflection block 241, and further avoiding the reflective layer 24 affecting the transmittance of the monochromatic light or infrared light.

[0048] See also Figure 6 In some embodiments, the reflective layer 24 includes a plurality of reflective blocks 241 corresponding to the black matrix 213 , and the sum of the thickness of the reflective blocks 241 and the thickness of the black matrix 213 is equal to the thickness of the color resist block 212 .

[0049] In order to solve the problem that the reflective layer 24 generally has a certain thickness, the monochromatic light or infrared light may irradiate the side of the reflective layer 24, thereby affecting the transmittance of the monochromatic light or infrared light to a certain extent, such as Figure 6 As shown, in the embodiment of the present application, the sum of the thickness of the reflective block 241 and the thickness of the black matrix 213 may be equal to the thickness of the color resist block 212 .

[0050] For example, on the basis that the thickness of the original black matrix 213 is equal to the thickness of the color resist block 212, a part of the area corresponding to each black matrix 213 can be hollowed out, and the hollowed-out area of ​​each black matrix 213 can be filled with the corresponding reflection block 241. In this way, there is no thickness difference between the reflection block 241 and the color resist block 212, which can avoid the phenomenon that when the monochromatic light or infrared light passes through the color resist block 212, it irradiates the side of the reflection block 241 and is reflected back, and further avoids the reflective layer 24 affecting the transmittance of the monochromatic light or infrared light.

[0051] See also Figure 7 and Figure 8 In some embodiments, the sensing layer 25 includes a plurality of spaced-apart light sensors 251, a light shielding layer 26 is disposed between the light sensors 251 and the array substrate 22, and a projection of the reflective layer 24 and the light sensors 251 in a direction perpendicular to the display panel 2 is located within a projection of the light shielding layer 26 in a direction perpendicular to the display panel 2.

[0052] If the infrared light source 1 is disposed on the side of the array substrate 22 away from the liquid crystal layer 23, that is, the infrared light source 1 is disposed below the display panel 2, the infrared light needs to first pass through the liquid crystal layer 23 from below the array substrate 22 to irradiate the user's finger, and then the infrared light reflected by the user's finger passes through the liquid crystal layer 23 and then irradiates the sensing layer 25. In this process, part of the infrared light emitted by the infrared light source 1 may be directly received by the sensing layer 25 without being reflected by the user's finger, or the infrared light that has not been reflected by the user's finger may be directly irradiated on the reflective layer 24 and reflected back to the sensing layer 25 by the reflective layer 24 and received by the sensing layer 25, thereby affecting the accuracy of gesture recognition.

[0053] In order to solve the above problems, Figure 7 As shown, in the embodiment of the present application, the sensing layer 25 may include a plurality of light sensors 251 arranged at intervals, a light shielding layer 26 is arranged between the light sensor 251 and the array substrate 22, and in a direction perpendicular to the display panel 2, the projection of the light sensor 251 may be located within the projection of the light shielding layer 26. That is, the light shielding layer 26 is arranged at a corresponding position of the light sensor 251, so that the infrared light emitted by the infrared light source 1 can be blocked by the light shielding layer 26 without being reflected by the user's finger, and thus cannot be directly received by the light sensor 251.

[0054] In addition, the projection of the reflective layer 24 in the direction perpendicular to the display panel 2 can also be located within the projection of the shading layer 26 in the direction perpendicular to the display panel 2. In other words, the reflective layer 24 can also be set at the corresponding positions of the shading layer 26 and the light sensor 251. In this way, the infrared light emitted by the infrared light source 1 can be blocked by the shading layer 26 without being reflected by the user's finger, so that it cannot be irradiated on the reflective layer 24, and then reflected by the reflective layer 24 to the sensing layer 25, and then received by the light sensor 251.

[0055] In the embodiments of the present application, Figure 8As shown, the infrared light emitted by the infrared light source 1 passes through the liquid crystal layer 23 from the gap between the light sensors 251, passes through the color block 212 and then irradiates the user's finger. The infrared light reflected by the user's finger passes through the color block 212 and then passes through the liquid crystal layer 23. Part of the infrared light irradiates the light sensor 251 and is received by the light sensor 251; part of the infrared light irradiates the light sensor 251 but is not received by the light sensor 251, but is reflected back; and part of the infrared light irradiates the gap between the light sensors 251 and then is reflected back. At this time, the infrared light that is not received by the light sensor 251 can be irradiated on the reflective layer 24 after reflection, and is reflected back to the light sensor 251 through the reflective layer 24, and then can be received by the light sensor 251. The utilization rate of infrared light is effectively improved, and the sensing amount of the sensing layer 25 is increased, thereby improving the accuracy of gesture recognition and reducing power consumption.

[0056] It can also be understood that in the embodiment of the present application, the light sensor 251 receives infrared light reflected by the user's finger. The infrared light that is not reflected by the user's finger is often not directly received by the light sensor 251 due to the action of the shading layer 26, thereby further ensuring the accuracy of gesture recognition.

[0057] See also Fig. 9 In some embodiments, a planarization layer 27 is disposed on the surface of the reflective layer 24 on the side close to the liquid crystal layer 23 .

[0058] like Fig. 9 As shown, a planarization layer 27 can be provided on the surface of the reflective layer 24 on the side close to the liquid crystal layer 23. The material of the planarization layer 27 can be a material with high light transmittance such as polyimide, acrylic series adhesive or pressure-sensitive adhesive. The planarization layer 27 is used to protect and planarize the surface of the reflective layer 24 on the side close to the liquid crystal layer 23.

[0059] For example, in the embodiment of the present application, polyimide or acrylic series adhesive materials (such as polyacrylate) can be used to prepare the planarization layer 27. These materials have good fluidity, making the preparation of the planarization layer 27 simpler and more convenient, and having a good planarization effect. Pressure-sensitive adhesive can also be used to prepare the planarization layer 27, so that the planarization layer 27 not only has a planarization effect, but also can achieve bonding of two layers of materials through the pressure-sensitive adhesive.

[0060] See also Fig.10 and Fig.11In some embodiments, the present application also provides a display device, and the display panel may include an infrared light source 1 and the above-mentioned display panel 2. The infrared light source 1 may be set at any position in the display device, and may emit infrared light to the display panel 2. For example, the infrared light source 1 may be set on at least one side of the display panel 2, or may be set below the display panel 2. The specific setting position is not specifically limited here.

[0061] like Fig.10 As shown, in some embodiments, the display panel 2 includes a display area 100 and a non-display area 101 disposed on at least one side of the display area 100 , and the infrared light source 1 is disposed at the non-display area 101 .

[0062] For example, the display panel 2 may include a display area 100 for display, and may also include a non-display area 101 such as a frame that is not used for display. The non-display area 101 may be arranged on at least one side of the display area 100, and the infrared light source 1 may be arranged at the non-display area 101. That is, the infrared light source 1 may emit infrared light from the side of the non-display area 101 to the display area 100, so that when the user makes a related gesture in the air in the display area 100, the infrared light may be irradiated on the user's finger, and then the infrared light reflected by the user's finger passes through the liquid crystal layer 23 and is received by the sensing layer 25, and then image information matching the gesture may be generated based on the user's gesture, and an image matching the image information may be displayed in the display area 100.

[0063] like Fig.11 As shown, in some embodiments, the infrared light source 1 is disposed on a side of the array substrate 22 away from the liquid crystal layer 23 .

[0064] In other words, the infrared light source 1 can be arranged below the display panel 2. For example, the display device can also include a backlight module 3, which is arranged on a side of the array substrate 22 away from the liquid crystal layer 23. The backlight module 3 can include a plurality of visible light emitting units, which can emit visible light to provide a basic light source for the display panel 2 to display images. Fig.11 As shown, the infrared light source 1 can be separately arranged on the side of the backlight module 3 close to the array substrate 22. It can be understood that the infrared light source 1 can also be separately arranged on the side of the backlight module 3 away from the array substrate 22. The infrared light source 1 can also be arranged at the corresponding position of the backlight module 3, that is, the backlight module 3 can include the infrared light source 1. For example, part of the visible light emitting units in the backlight module 3 can be replaced by the infrared light source 1.
