Display modules and electronic devices

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on September 4, 2023, with application number 202311132740.6 and title “Display Module and Electronic Device,” the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a display module and electronic equipment. Background Art

[0004] With the development of communication technology, the functions of electronic devices are becoming more and more abundant, and users' requirements for electronic devices are also getting higher and higher. Based on 2D display, the 3D display effect of display modules is also attracting more and more attention.

[0005] In the prior art, the parallax barrier method is mainly used. The display module includes a display layer and a barrier layer, wherein the display layer includes a left-eye display unit and a right-eye display unit arranged alternately. The barrier layer includes a plurality of barrier gratings arranged at intervals. By setting the spacing between two adjacent barrier gratings, the light from the left-eye display unit enters the user's left eye, and the light from the right-eye display unit enters the user's right eye. As a result, the user's left eye and right eye see different images, respectively, achieving a 3D display effect.

[0006] However, in the process of studying the existing technology, the inventors found that in the existing technology, light can only be emitted from between two adjacent barrier gratings within a certain angle range. If the user moves during the viewing process, or when the display module shakes in scenarios such as playing games, it is difficult for light to enter the user's left and right eyes respectively, resulting in poor 3D display effect and dizziness.

[0007] Summary of the Invention

[0008] In view of the above problems, the present invention is proposed to provide a display module and an electronic device that overcome the problem of poor 3D display effect caused by the movement of the user or the shaking of the display module.

[0009] In order to solve the above technical problems, this application is implemented as follows:

[0010] In a first aspect, an embodiment of the present application provides a display module, comprising a substrate layer, a light-emitting layer, a light-guiding layer, and an encapsulation layer connected in sequence;

[0011] The light emitting layer includes a plurality of pixel units distributed in an array, the light guide layer includes a plurality of light guide members, and the light guide members are staggered with the pixel units;

[0012] Among two adjacent pixel units, one pixel unit emits a first light and the other pixel unit emits a second light. The first light passes through the light guide and enters the first area, and the second light passes through the light guide and enters the second area. The first light intersects with the second light.

[0013] In a second aspect, an embodiment of the present application provides an electronic device, which includes the display module.

[0014] In an embodiment of the present application, the display module includes a substrate layer, a light-emitting layer, a light-guiding layer, and an encapsulation layer connected in sequence; the light-emitting layer includes a plurality of pixel units distributed in an array; the light-guiding layer includes a plurality of deformable light-guiding members, the light-guiding members being staggered relative to the pixel units; one of two adjacent pixel units emits a first light ray and the other emits a second light ray, the first light ray passing through the light-guiding member into a first region and the second light ray passing through the light-guiding member into a second region; wherein the first light ray intersects the second light ray. Thus, when a 3D effect is required, the light-guiding member near one of the pixel units can direct the first light ray into the first region, thereby deflecting the first light ray emitted by the pixel unit displaying the first image to the first region, and the light-guiding member near the other pixel unit can direct the second light ray into the second region, thereby deflecting the second light ray emitted by the pixel unit displaying the second image to the second region. Thus, the light-guiding member can adjust the directions of the first and second light rays according to the locations of the first and second regions, so that the display module has a more stable 3D display effect. This eliminates the need to keep the user's viewpoint and perspective stable, avoiding movement during viewing, or jittering of the display module in scenarios such as gaming, which can lead to poor 3D display effects and dizziness, thereby improving the user experience.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0034] 1 to 11 , schematic diagrams of the structure of a display module according to an embodiment of the present application are shown, wherein the dotted arrows indicate the direction of light emission. FIG12 , schematic diagram of the display process of the display module according to an embodiment of the present application, is shown. The display module may specifically include: a substrate layer 100, a light-emitting layer 200, a light-guiding layer 300, and an encapsulation layer 400 connected in sequence;

[0035] The light emitting layer 200 includes a plurality of pixel units 210 distributed in an array, and the light guide layer 300 includes a plurality of deformable light guide members 310 , which are staggered with the pixel units 210 ;

[0036] Among two adjacent pixel units 210, one pixel unit 210 emits a first light, and the other pixel unit 210 emits a second light. The first light passes through the light guide 310 and enters the first area 211. The second light passes through the light guide 310 and enters the second area 212.

[0037] The first light ray intersects with the second light ray.

[0038] In an embodiment of the present application, the first light and the second light intersect, that is, the first light and the second light are light rays with different emission directions. When a 3D effect is required, the light guide 310 close to one of the pixel units 210 can inject the first light into the first area 211 to deflect the first light emitted by the pixel unit 210 displaying the first picture to the first area 211, and the light guide 310 close to another pixel unit 210 can inject the second light into the second area 212 to deflect the second light emitted by the pixel unit 210 displaying the second picture to the second area 212. Thus, the light guide 310 can adjust the directions of the first light and the second light according to the positions of the first area 211 and the second area, so that the display module has a more stable 3D display effect. There is no need to keep the user's viewpoint and viewing angle stable, which avoids the user from moving during the viewing process, or when the display module shakes in scenes such as playing games, resulting in poor 3D display effect, dizziness, etc., thereby improving the user experience.

[0039] Specifically, in an embodiment of the present application, the user's right eye can be located in the first area 211, and the user's left eye can be located in the second area 212. One pixel unit 210 emits a first light beam for entering the user's right eye to form a first image, and another pixel unit 210 emits a second light beam for entering the user's left eye to form a second image. The image positions of the first and second images are slightly offset. The first light beams emitted by one of the pixel units 210 are deflected by the light guide 310 near one of the pixel units 210, causing the first light beams to reach the first area 211, i.e., the user's right eye, forming the first image. Furthermore, the second light beams emitted by another pixel unit 210 are deflected by the light guide 310 near another pixel unit 210, causing the second light beams to reach the second area 212, i.e., the user's left eye, forming the second image. Thus, the user's left and right eyes perceive different first and second images, creating a 3D display effect. Alternatively, the user's left eye can be located in the first area 211, and the user's right eye can be located in the second area 212, which is not limited in this embodiment of the present application.

[0040] If the user moves or the display module moves, the first area 211 and the second area 212 change, and the light guide 310 adjusts each light guide 310 accordingly so that the first light of one pixel unit 210 is still deflected to the first area 211, and the second light of another pixel unit 210 is still deflected to the second area 212, thereby forming a more stable 3D display effect.

[0041] When there is no need to display a 3D effect, the light guide 310 has no effect on the light emitted by the pixel unit 210, that is, the first area 211 can receive the first light from one of the pixel units 210 and the second light from another pixel unit 210, and the second area 212 can also receive the first light from one of the pixel units 210 and the second light from another pixel unit 210, thereby realizing switching of 2D effects.

[0042] For example, in the embodiment of the present application, the display module can be a liquid crystal display (Liquid Crystal Display, LCD), an organic light emitting diode display (Organic Light Emitting Diode, OLED), a micro light emitting diode display (Micro Light Emitting Diode, Micro LED), etc. The specific type of the display module is not limited in the embodiment of the present application.

[0043] In the embodiment of the present application, specifically, the pixel unit 210 may include multiple sub-pixels, and the light guide 310 is staggered with each of the sub-pixels, further improving the accuracy of the light guide 310 in deflecting the light emitted by the pixel unit 210.

[0044] For example, in an embodiment of the present application, the multiple array-distributed pixel units 210 form a pixel array, and the light guide 310 can extend along the longitudinal direction of the pixel array to achieve a longitudinal 3D effect, so that the light guide 310 close to one of the pixel units 210 can simultaneously deflect the first light emitted by multiple pixel units 210 in the longitudinal direction, and the light guide 310 close to another pixel unit 210 can simultaneously deflect the second light emitted by multiple other pixel units 210 in the longitudinal direction, thereby improving the efficiency of the guide.

[0045] In addition, the light guide 310 can also extend along the lateral direction of the pixel array to achieve a lateral 3D effect, so that the light guide 310 close to one of the pixel units 210 can simultaneously deflect the first light emitted by multiple pixel units 210 in the lateral direction, and the light guide 310 close to another pixel unit 210 can simultaneously deflect the second light emitted by multiple other pixel units 210 in the lateral direction, thereby improving the efficiency of the guide.

[0046] For example, in the embodiment of the present application, the light guide 310 may be a rectangular parallelepiped or a cube, etc., and the size of the light guide 310 may be set according to the size of the pixel unit 210. For example, if the length and width of the sub-pixels in the pixel unit 210 may be 5um*5um, and the gap between two adjacent sub-pixels is 5um, then the height of the light guide gap may be 1 to 10um, such as 8um. The light guides 310 at different positions may be set to different heights, and the width may be set to 1um to 5um, etc., according to actual needs. The embodiment of the present application does not limit the specific shape and size of the light guide 310.

[0047] In the embodiment of the present application, the light guide 310 can bend, elongate, contract, twist, or undergo other deformations under the influence of an electric field or a magnetic field. The light guide 310 can be made of a metal with high reflectivity, such as silver, zinc, or titanium. Alternatively, the light guide 310 can be made of a non-metal with a highly reflective coating. The material of the light guide 310 is not limited in the embodiment of the present application.

[0048] For example, in the embodiment of the present application, the substrate layer 100 may include a lower base material layer and a backplane foam aluminum foil layer to provide relatively stable and reliable support for the display module. For example, the lower substrate layer 100 may include a circuit layer for driving the pixel unit 210, such as a thin film transistor (TFT), and its material may be peel-off or plastic, etc., which is not limited in the embodiment of the present application.

[0049] In the embodiment of the present application, for example, the encapsulation layer 400 may include an upper sealing layer, a polarizer, and a cover plate connected in sequence, providing a good seal between the light-emitting layer 200 and the light-guiding layer 300. The upper sealing layer is connected to the light-guiding layer 300 and may be made of a peel-off material or plastic. The cover plate and the polarizer layer may be bonded using optical double-sided tape, ensuring a strong connection between the two.

[0050] In some optional embodiments of the present application, the light guide layer 300 may further be provided with a support plate connected between the upper sealing layer and the light-emitting layer 200 to provide relatively stable and reliable support for the light guide layer 300. The light guide layer 300 may be provided with a cavity, and the light guide member 310 may be disposed within the cavity. For example, the cavity may be a vacuum cavity, so that the light guide member 310 experiences little resistance to deformation within the cavity and exhibits good deformation smoothness. Furthermore, the cavity may be filled with a gas, such as an inert gas, or a liquid, such as liquid nitrogen or liquid crystal. The embodiments of the present application do not limit the filler within the cavity.

[0051] Specifically, in the embodiment of the present application, the display module further includes an insulating layer, which is connected between the light-emitting layer 200 and the light-guiding layer 300 to insulate the pixel units 210 on the light-emitting layer 200 from the light-guiding member 310 on the light-guiding layer 300, thereby preventing interference between the circuits of the two. For example, the insulating layer can be made of an organic material, such as a resin, or an inorganic material, such as silicon dioxide, etc. The number of insulating layers can be one, two, or three, etc. The specific material and number of the insulating layers are not limited in the embodiment of the present application.

[0052] Optionally, in this embodiment of the present application, the light guide layer 300 includes a first light guide layer and a second light guide layer connected to each other. The light guide element 310 disposed on the first light guide layer is a first light guide element 320, extending along a first direction X. The light guide element 310 disposed on the second light guide layer is a second light guide element 330, extending along a second direction Y. The first direction X is perpendicular to the second direction Y. This allows the light guide layer 300 to simultaneously control the display module in both the first direction X and the second direction Y, i.e., both horizontally and vertically, achieving a better display quality. Furthermore, since the first light guide element 320 and the second light guide element 330 are disposed on the second light guide layer, the first light guide element 320 extending along the first direction and the second light guide element 330 extending along the second direction Y can be controlled separately without interfering with each other. That is, the first light guide 320 can be controlled alone to produce deformation to achieve a 3D effect in the first direction X, or the second light guide 330 can be controlled alone to produce deformation to achieve a 3D effect in the second direction Y. It is also possible to control both the first light guide 320 and the second light guide 330 to produce deformation to achieve a 3D effect in both the first direction X and the second direction Y, with good control accuracy, and the embodiments of the present application are not limited to this.

[0053] In the embodiment of the present application, the light guide members 310 extending in the first direction X in the light guide layer 300 are optionally third light guide members 340, and the light guide members 310 extending in the second direction Y in the light guide layer 300 are fourth light guide members 350. The third light guide members 340 and the fourth light guide members 350 are arranged alternately. The first direction X is perpendicular to the second direction Y. In other words, by simultaneously providing the third light guide members 340 extending in the first direction X and the fourth light guide members 350 extending in the second direction Y in the light guide layer 300, the light guide layer 300 can achieve a 3D effect in both the first direction X and the second direction Y without increasing the number of light guide layers 300, resulting in a better display quality. The third light guide members 340 extending in the first direction and the fourth light guide members 350 extending in the second direction Y can be controlled separately according to actual needs.

[0054] Specifically, as shown in Figures 10 and 11, in the embodiment of the present application, the third light guide member 340 includes a plurality of first light guide plates 341 and a plurality of first connecting portions 342. The plurality of first light guide plates 341 are spaced apart along a first direction X, and the first connecting portions 342 connect between two adjacent first light guide plates 341. The fourth light guide member 350 includes a plurality of second light guide plates 351 and a plurality of second connecting portions 352. The plurality of second light guide plates 351 are spaced apart along a second direction Y, and the second connecting portions 352 connect between two adjacent second light guide plates 351. The first connecting portions 342 and the second connecting portions 352 are arranged in an alternating manner. In this way, the connection between two adjacent first light guide plates 341 is achieved through the first connecting portions 342, and the connection between two adjacent second light guide plates 351 is achieved through the second connecting portions 352. The alternating arrangement of the first connecting portions 342 and the second connecting portions 352 realizes the alternating arrangement of the third light guide plate and the fourth light guide plate.

[0055] In the embodiment of the present application, specifically, the first connecting portion 342 can be a relatively small connecting piece, a first groove is formed between two adjacent first light guide plates 341 and the first connecting portion 342, and the second connecting portion 352 is disposed in the first groove. Similarly, the second connecting portion 352 can also be a relatively small connecting piece, a second groove is formed between two adjacent second light guide plates 351 and the second connecting portion 352, and the first connecting portion 342 is disposed in the second groove, thereby achieving a staggered arrangement between the third light guide 340 and the fourth light guide 350.

[0056] In some optional embodiments of the present application, the light guide layer 300 is further provided with an insulating plate, which is connected between the first connecting portion 342 and the second connecting portion 352. Thus, while the third light guide 340 and the fourth light guide 350 are staggeredly connected, the insulating plate electrically isolates the first connecting portion 342 and the second connecting portion 352 of the third light guide 340 and the fourth light guide 350 from each other, preventing electrical interference between the third light guide 340 and the fourth light guide 350, which could affect the display effect.

[0057] Optionally, in this embodiment of the present application, the display module further includes a touch line 220, which is electrically connected to the light guide 310 to implement the touch function through the light guide 310. In this way, the light guide 310 can be used as a touch sensing channel to implement the touch function of the display module, eliminating the need for a separate touch layer, simplifying the overall structure of the display module and facilitating a miniaturized product design.

[0058] Specifically, in the embodiment of the present application, the touch line 220 includes multiple touch channels. Each touch channel can be composed of multiple light guides 310. The touch channels can include a first direction X channel and a second direction Y channel, so as to achieve good touch function in both the first direction X and the second direction Y. Typically, the display module also includes an integrated circuit, and the multiple touch channels are electrically connected to the integrated circuit to achieve communication between the touch channels and the integrated circuit.

[0059] For example, in the embodiment of the present application, the width of the touch channel can be set to any value between 0.1 mm and 10 mm, such as 3 mm, 4 mm, 5 mm, etc., and can be set according to actual needs. The embodiment of the present application does not limit this.

[0060] In the embodiment of the present application, the display module further includes a driver, which is disposed in the light guide layer 300 and connected to the light guide 310. The light guide 310 is deformable. The driver drives the light guide 310 near one of the pixel units 210 to deflect toward the first region 211, or drives the light guide 310 near another pixel unit 210 to deflect toward the second region 212. The driver provides a relatively stable and reliable driving force for the deformation of the light guide 310, allowing the light guide 310 to deflect toward the first region 211 or the second region 212, thereby providing a more precise guiding effect on light.

[0061] Optionally, in an embodiment of the present application, as shown in FIG8 , the driving member includes a first electrode 510 and a second electrode 520, and the light guide 310 includes a first end 311 and a second end 312 disposed opposite each other, wherein the first end 311 is connected to the light guide layer 300; the first electrode 510 is connected to the first end 311, and the second electrode 520 is connected to the light guide layer 300 near the second end 312. The first electrode 510 and the second electrode 520 drive the second end 312 of the light guide 310 to deflect toward the first region 211 or the second region 212. An electric field is formed by the first electrode 510 and the second electrode 520, and the first end 311 of the light guide 310 is fixedly connected to the light guide layer 300. Under the action of the electric field, the second end 312 of the light guide 310 is deformed to deflect light emitted by the pixel unit 210 toward the first region 211 or the second region 212.

[0062] For example, in the embodiment of the present application, if the second electrode 520 carries a positive charge and the first electrode 510 carries a negative charge, an electric field force is generated in the direction from the first electrode 510 to the second electrode 520, causing the negatively charged light guide 310 to deform and deflect toward the second electrode 520, thereby causing the light guide 310 to deflect the first light emitted by the adjacent pixel unit 210 toward the first region 211. By controlling the voltage, current, and intensity of the electric field, the size and shape of the deformation of the light guide 310 can be adjusted, achieving more precise deformation control of the light guide 310.

[0063] In the embodiment of the present application, for example, the second electrode 520 can be made of indium tin oxide (ITO), which can provide a relatively stable and reliable electric field when powered. Indium tin oxide is a transparent material and can also reduce the impact on the light path.

[0064] In some optional embodiments of the present application, as shown in FIG9 , the driving element includes a third electrode 530 and a fourth electrode 540 , and the light guide 310 includes a first side 313 and a second side 314 arranged opposite each other; the third electrode 530 is connected to the first side 313 , and the fourth electrode 540 is connected to the second side 314 , and the third electrode 530 and the fourth electrode 540 drive the light guide 310 to deflect toward the first region 211 or the second region 212 . In this way, the third electrode 530 and the fourth electrode 540 can also be provided on the first side 313 and the second side 314 of the light guide 310 , that is, on its left and right sides, and can also provide a relatively stable and reliable driving force for the deformation of the light guide 310 . By controlling the voltage of the third electrode 530 and the fourth electrode 540 , the deformation of the light guide 310 is controlled, so that it deflects the light of the pixel unit 210 .

[0065] For example, in the embodiment of the present application, the third electrode 530 may be an electroactive polymer (EAP) or an ion-exchange polymer metal composite (IPMC), and the fourth electrode 540 may be an electroactive polymer (EAP) or an ion-exchange polymer metal composite (IPMC). The embodiment of the present application does not limit the specific types of the third electrode 530 and the fourth electrode.

[0066] Optionally, in an embodiment of the present application, the display module further includes a controller 610, a distance sensor 620 and a shape detector 630, the controller 610 is electrically connected to the distance sensor 620 and the shape detector 630, respectively, and the multiple light guides 310 are electrically connected to the controller 610, respectively; the distance sensor 620 is used to detect a first distance between the first area 211 and the second area 212, and a second distance between the first area 211 and / or the second area 212 and the display module, and the shape detector 630 is used to detect the spatial shape of the display module; the controller 610 adjusts the deflection angle of the light guide 310 based on the first distance and the second distance detected by the distance sensor 620, and the spatial shape of the display module detected by the shape detector 630. Thus, the light guide 310 near one of the pixel units 210 is deflected toward the first area 211 at an appropriate angle to deflect the first light emitted by the pixel unit 210 displaying the first picture to the first area 211, and the light guide 310 near another pixel unit 210 is deflected toward the second area 212 at an appropriate angle to deflect the second light emitted by the pixel unit 210 displaying the second picture to the second area 212. The emission directions of the first light and the second light are adjusted so that the display module has a more stable 3D display effect.

[0067] In this way, the state between the user and the display module can be detected in real time by the controller 610, the distance sensor 620, and the shape detector 630, so that the deflection angle of the light guide 310 caused by deformation can be adjusted in a timely manner according to the real-time state. When the user moves, the distance sensor 620 detects changes in the first area 211 and the second area 212, that is, changes in the positions of the user's left and right eyes, and changes in the second distance between the first area 211 and / or the second area 212 and the display module, that is, changes in the relative position between the user and the display module. The shape detector 630 also detects the spatial shape of the display module, such as the horizontal state of the display module, whether it is tilted, etc., and transmits the above position information and spatial shape information to the controller 610. The controller 610 can adjust the deflection angle of the light guide 310 in a timely manner according to the position changes caused by the user's movement and the position or shape changes of the display module, so that the display module has a better 3D display effect.

[0068] For example, in this embodiment of the present application, the shape detector 630 may include a gyroscopic angle sensor and an angle sensor to detect the shape of the display module, such as the tilt angle, horizontal height, and other spatial shape information. Then, combined with the distance between the user's eyes detected by the distance sensor 620 and the distance between the user and the display module, the chip automatically calculates and adjusts the optimal voltage output by the driver to adjust the deformation and angle of the light guide 310, thereby adjusting the angle of the light emitted by the pixel unit 210.

[0069] In an embodiment of the present application, for example, as shown in FIG12 , when 3D display needs to be turned on, the 3D function is started by clicking or voice control, and then the first spacing between the first area 211 and the second area 212, as well as the second spacing between the first area 211 and / or the second area 212 and the display module are obtained through the distance sensor 620, and the spatial morphology information of the display module is detected by the morphology detector 630. Then, the controller 610, such as the central processing unit (CPU), obtains the above-mentioned first spacing, second spacing and spatial morphology information, and calculates the light output angle of each pixel unit 210. Then, the controller 610 outputs an angle adjustment instruction to each light guide 310 to adjust the deflection angle of each light guide 310 to produce deformation. Then, the controller 610 outputs an image to the integrated circuit of the display module, outputting the images of the first area 211 and the second area 212, that is, the pixel units 210 corresponding to the left eye and right eye of the user, so that the user obtains a 3D image. During the display process, the distance sensor 620 and the shape detector 630 can periodically or in real time detect whether the above-mentioned first spacing, second spacing and spatial shape information have changed. If so, the changed first spacing, second spacing and spatial shape information are obtained and the light output angle of each pixel unit 210 is recalculated, and the deflection angle of the light guide 310 is adjusted; if not, the original parameters are maintained.

[0070] In summary, the display module described in the embodiments of the present application can at least include the following advantages:

[0071] In an embodiment of the present application, the display module includes a substrate layer, a light-emitting layer, a light-guiding layer, and an encapsulation layer connected in sequence; the light-emitting layer includes a plurality of pixel units distributed in an array; the light-guiding layer includes a plurality of deformable light-guiding members, the light-guiding members being staggered relative to the pixel units; one of two adjacent pixel units emits a first light ray and the other emits a second light ray, the first light ray passing through the light-guiding member into a first region and the second light ray passing through the light-guiding member into a second region; wherein the first light ray intersects the second light ray. Thus, when a 3D effect is required, the light-guiding member near one of the pixel units can direct the first light ray into the first region, thereby deflecting the first light ray emitted by the pixel unit displaying the first image to the first region, and the light-guiding member near the other pixel unit can direct the second light ray into the second region, thereby deflecting the second light ray emitted by the pixel unit displaying the second image to the second region. Thus, the light-guiding member can adjust the directions of the first and second light rays according to the locations of the first and second regions, so that the display module has a more stable 3D display effect. This eliminates the need to keep the user's viewpoint and perspective stable, avoiding movement during viewing, or jittering of the display module in scenarios such as gaming, which can lead to poor 3D display effects and dizziness, thereby improving the user experience.

[0072] An embodiment of the present application further provides an electronic device, which includes the display module.

In this way, when a 3D effect is required, the light-guiding member near one of the pixel units can emit the first light ray into the first region to deflect the first light ray emitted by the pixel unit displaying the first image to the first region, and the light-guiding member near the other pixel unit can emit the second light ray into the second region to deflect the second light ray emitted by the pixel unit displaying the second image to the second region. In this way, the light-guiding member can adjust the directions of the first and second light rays according to the positions of the first and second regions, so that the display module has a more stable 3D display effect. This eliminates the need to keep the user's viewpoint and perspective stable, avoiding movement during viewing, or jittering of the display module in scenarios such as gaming, which can lead to poor 3D display effects and dizziness, thereby improving the user experience.
