For example, in order to display "1", all the lights around "1" need to be turned off. If the number of Mini LED lights is enough, or even the number of Mini LED lights can form a "1" shape, the halo problem will be greatly improved. , but increasing the number of Mini LEDs will cause a significant increase in the cost of the entire machine.

Here, the lens unit 1041 can be a solid variable focus film of polydimethylsiloxane (PDMS), or various types of liquid lenses. The liquid interface of the liquid lens interacts with surface tension. A layer of symmetrical lens film is naturally formed under the lens, and the focal length of the lens is fixed at this time; when a voltage is applied to the lens, under the action of the electric field, the electric charge between the contact surfaces changes, thus producing a surface that changes the original surface. The external forces that are no longer balanced between tensions reach a new balance under the action of external forces, thus changing the radius of curvature of the lens surface and thus changing the focal length of the lens. Different applied voltages result in different surface tensions required to achieve a steady state between the two liquids and the liquid and the wall. People adjust the applied voltage to change the curvature of the liquid interface, and thereby change the focal length of the liquid lens.

The embodiment of the present application can take a positive electrode as an example (negative electrodes can also be used), where the positive electrode The voltage of the electrode can be set to 0V. By adjusting the voltage value applied to the negative electrode, the surface topography of the lens unit 1041 can be changed or the refractive index of the lens body can be changed, thereby adjusting the focal length of the lens unit and realizing the zoom function.

In some embodiments, the display device further includes a processor. Figure 7 is a schematic flowchart of a processing method provided by an embodiment of the present application. The execution subject of the processing method does not include the processor of the display device. As shown in Figure 7, The processing method is implemented through steps S701 to S702:

Step S701: Obtain a driving signal, which is used to drive the dimming module.

In some embodiments, a signal processing chip (such as a scalar chip) in the display device obtains a video signal (such as a High Definition Multimedia Interface (HDMI) signal) from the graphics card, and the scalar chip converts the video signal into a display signal, The display signal is a signal that can be directly recognized by the display panel of the display device (such as Low-Voltage Differential Signaling (LVDS)). The display signal is used to control the pixel unit of the display panel, generally to control the brightness of the light-emitting unit. The voltage signal, or the voltage signal that controls the conduction of the liquid crystal layer, is determined as the driving signal.

Step S702: Output the driving signal to the dimming module so that the dimming module can influence the light-emitting unit to illuminate the first pixel area of the display panel with the light of the light-emitting unit. The number of pixel units included in the first pixel area is smaller than the number of pixel units included in the second pixel area. The second pixel area is where the light of the light-emitting unit is not affected by the dimming module. In this case, the pixel area of the display panel is illuminated.

In some embodiments, the processor obtains the driving signal and controls the dimming module to adjust the light emitted by the light-emitting unit based on the driving signal.

In some embodiments, the dimming module may include a lens unit and a first adjustment unit. The lens unit is disposed on a side of the light-emitting unit that emits light. The lens unit corresponds to the light-emitting unit, and the focal length of the lens unit can be adjusted. The driving signal includes a first driving signal, and the processor controls the first adjustment unit to adjust the focal length of the lens unit in response to the first driving signal.

In some embodiments, the dimming module may also include a lens unit and a second adjustment unit. The lens unit is disposed on the side of the light-emitting unit that emits light. The lens unit corresponds to the light-emitting unit. The distance between the lens unit and the light-emitting unit can be adjusted. ; wherein the drive signal includes a second drive signal; the processor controls the second adjustment unit to adjust the distance between the lens unit and the light-emitting unit based on the second drive signal.

In some embodiments, the first adjustment unit and the second adjustment unit may coexist in the dimming module. Either one is used or they are used simultaneously according to the needs, that is, the distance between the lens unit and the light-emitting unit is changed, and the distance between the lens unit and the light-emitting unit is changed. The focal length of the unit, thereby changing the direction of travel of the light emitted by the light-emitting unit.

The embodiments of the present application process the light of the light-emitting unit by adding a layer of lens units with adjustable curvature on the surface of the light-emitting unit. At the same time, the processor can accurately adjust the curvature of the lens unit corresponding to each light-emitting unit to change the lens unit. the focal length. In this way, in areas where a dark state is required, the light of the illuminated light-emitting unit can be changed from stray light to parallel light, and in areas where a bright state is required, the curvature of the lens unit can be adjusted to further diffuse the light, thereby improving the light efficiency. utilization rate. Embodiments of the present application can reduce the Halo degree in the dark state area without increasing the number of lights in the light-emitting unit, and can also improve the utilization rate of light in the bright state area, thereby reducing the number of lights in the light-emitting unit and thereby reducing costs.

The embodiment of this application further provides an application of the processing method in actual scenarios.

In order to reduce the halo phenomenon of the display device, the embodiment of the present application implements the light processing of the Mini LED by adding an optical lens layer (ie, the lens unit) with adjustable curvature on the surface of the Mini LED (ie, the light-emitting unit). At the same time, the curvature of the optical lens corresponding to each Mini LED can be accurately adjusted through algorithms. The light of the lit Mini LED is changed from stray light to parallel light in the area where dark state is required. In areas where a bright state is required, the curvature of the optical lens is adjusted to further diverge, thereby improving light utilization. Using the display device provided by the embodiment of the present application can not only reduce the Halo degree in the dark area without increasing the number of Mini LED lights, but also improve the light utilization rate in the bright area, thereby reducing the number of Mini LED lights. , thereby reducing costs.

In order to reduce Halo, this application proposes two feasible solutions. The first solution is that a variable optical lens layer (ie, lens unit) can be packaged on the surface of each Mini LED (ie, light-emitting unit). This solution can better combine optical lenses with Mini LED (light-emitting unit) lights. It is not only simple to package, but also can effectively change the direction of light. During production, this solution requires that each min-LED (i.e., light-emitting unit) undergo complete electrical and optical performance testing before the optical lens layer (i.e., lens unit) can be packaged to ensure product yield.

Here, common components of Mini LED, such as substrates, Mini LED lamp beads and packaging materials, can be produced according to processes in related technologies, and these components can be assembled. The optical lens layer (i.e., lens unit) can use solid-state variable focus films of PDMS, as well as various types of liquid lenses, etc. In embodiments of the present application, materials with electrowetting structures can be used to design liquid-phase variable focus lenses. The response speed of the electrowetting structure lens can reach 10ms, which can realize the zoom function quickly and accurately. The variable lens layer and the Mini LED lamp beads are packaged, and then the corresponding diffuser, module frame and other components are assembled, and relevant tests are completed to finally produce the backlight module (Mini LED BLU) of the display device. Finally, the backlight module and the corresponding liquid crystal panel (Open Cell) are assembled together to form a Mini LED display (panel), and are assembled with other complete components to form the display device provided by the embodiment of the present application.

The second option is for the variable optical lens layer (i.e., lens unit) to be placed on the surface of the Mini LED as a separate film material. The lens layer (i.e. lens unit) can be used as a separate component, which needs to be produced in advance and then assembled with the Mini LED lamp. In this solution, there may be a certain gap between the Mini LED light and the lens layer. Therefore, the relationship between the curvature of the lens and the gap needs to be controlled to ensure that the optical lens layer can effectively process the Mini LED light. In addition, in order to ensure the reduction of The effect of Halo requires controlling the accuracy of assembly during the assembly process.

Here, the variable lens film layer can be prepared using PDMS material. Before preparation, it is necessary to produce a Glass substrate with electrodes. After the Glass substrate with electrodes is produced, the microstructure of the lens can be formed through processes such as glue coating, exposure, and etching. On this basis, a film is formed on its surface. , exposure, etching and other processes to form corresponding electrodes, and finally after cleaning, the variable lens film layer provided in the embodiment of the present application is formed. After the preparation of the diaphragm with the variable lens film layer, the assembly process needs to be completed. During the assembly process, it is necessary to ensure precise alignment of the lens and the Mini LED lamp beads. Therefore, it is necessary to set the corresponding alignment mask (Mark) on the diaphragm of the variable lens layer, and it is also necessary to set the corresponding alignment Mark on the Mini LED backplane to ensure the accuracy of alignment. Finally, assemble according to the assembly steps in Scheme 1 to obtain a display device.

The embodiment of the present application adds a variable optical lens layer to the Mini LED to modulate the light emitted by the Mini LED from stray light to parallel light, thereby reducing the impact of different Mini LED lights on surrounding pixels. Lower Halo. Compared with related technologies, this application can achieve high-quality Mini LED products without increasing the number of Mini LEDs without increasing costs. This application can be combined with algorithms to control the light of lamp beads in different areas. It can not only change stray light into parallel light, but also make stray light more uniform, which can improve the utilization rate of Mini LED light sources and can also reduce Number of Mini LED lights.

The embodiments of this application provide two implementation solutions. The two solutions have different requirements for Mini LED design and process capabilities. Actual producers can choose which solution to adopt based on production capacity. Option 1 can not only adjust the light, but if the technology is mature, the lens layer and the Mini LED can even be merged together to act as a protective layer, which can further reduce costs without affecting the effect.

The optical lens layer provided by the embodiments of the present application can use various types of liquid lenses, such as materials with electrowetting structures, or can also use solid-state variable focus materials, such as PDMS materials.

The device provided by the embodiment of the present application is not affected by the size of the display panel (Panel). Whether it is for large-sized displays or small- and medium-sized displays, it can be applied to products that use Mini LED technology.

The optical lens layer involved in the embodiment of the present application needs to have an adjustable curvature. However, in order to simplify production, it can also meet the requirements if the curvature of the optical lens layer is non-adjustable, but it is necessary to have a preset for the curvature of the lens layer. value, and the default value should be set after comprehensive consideration of the number of Mini LED lights, light intensity, and the transmittance of the liquid crystal layer (Open Cell).
