Description

Technical Field

[0001] The present application belongs to the field of display technology, and in particular, relates to a pixel design control system, method, display device and storage medium. Background Art

[0002] The current in-vehicle anti-peeping solutions in the industry still have some obvious defects. For example, in the passive anti-peeping solution, most of them add an anti-peeping film in the backlight of the module or use the design of the light guide plate network to achieve anti-peeping, but this solution will seriously affect the overall brightness of the display system. When the number of backlight LEDs is the same, the brightness attenuation of the anti-peeping solution is serious. Therefore, if the same brightness is required, more LEDs are required, and the screen heats up more seriously. In the daytime, when the ambient light is sufficient and anti-peeping is not needed, it cannot be turned off, and the system power consumption is higher. In addition, the anti-peeping film is relatively poorly customizable, and the anti-peeping angle is relatively poorly controllable. For large-size screens, the picture display uniformity is prone to poor. In the active anti-peeping solution, the anti-peeping effect of active identification opening and closing can be achieved, but most of the solutions use dual light guide plates, the anti-peeping effect is not ideal, only the entire surface can be anti-peeping, and the system structure is complex; most of them use ordinary liquid crystal boxes for anti-peeping, the anti-peeping angle control is relatively poor, and only the entire surface can be anti-peeping, and the actual application display effect is poor; and most of them use dual or multiple liquid crystal cells to construct the display panel for anti-peeping, which easily leads to a thicker overall structure size, which is contrary to the concept of lightweight design for vehicles, and the cost is also high.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Embodiment 1: As shown in FIG. 1 , in order to solve the above technical problems, the present application provides a pixel design control system, including: Several pixel units and driving units; wherein any of the pixel units includes a plurality of pixels, and the pixels include sub-pixels of multiple colors; and also includes a switch control unit.

[0026] It should be noted that in this embodiment, each color sub-pixel is no longer regarded as a whole, but is physically divided into several independently controlled areas, thereby allowing regional control of the screen display content, so that only users at a specific angle can see all the content, while users at other angles can hardly see the content at all. This greatly enhances anti-peeping privacy protection, that is, according to different usage scenarios and user needs, it is possible to dynamically adjust which areas activate the anti-peeping function and which areas maintain normal display.

[0027] For example, in the vehicle display system, the anti-peeping function is turned off within the driver's field of vision, and turned on within the field of vision of the co-pilot or the back seat. This will prevent the display content of the co-pilot screen from being visible from the driver's viewing angle, thereby preventing the information on the co-pilot screen from distracting the driver and causing driving safety accidents.

[0028] In this embodiment, the pixel design control system is specifically: Any of the color sub-pixels is composed of a plurality of sub-pixel regions; the sub-pixel regions are respectively connected to the first end of the switch control unit, the second end of the switch control unit is connected to one end of the driving unit, and the third end of the switch control unit is connected to an external control source, for receiving a first control signal and / or a second control signal output by the external control source; wherein the set number of the driving unit and the switch control unit is the same as the number of color sub-pixels, and each of the switch control units is only connected to a corresponding sub-pixel region in a color sub-pixel; the first control signal is used to independently control the activation of any of the sub-pixel regions; and the second control signal is used to independently control the closure of any of the sub-pixel regions.

[0029] It should be noted that color sub-pixels generally include R sub-pixels, G sub-pixels and B sub-pixels. In a color display screen, a color sub-pixel refers to a single color unit that makes up a pixel. In standard RGB display technology, a pixel is composed of three sub-pixels, which emit red, green and blue light respectively, namely RGB sub-pixels.

[0030] In this embodiment, each originally single sub-pixel, for example, a red sub-pixel, a green sub-pixel or a blue sub-pixel is physically or logically divided into smaller area portions, and each of the switch control units is independently controlled.

[0031] Preferably, the color sub-pixel can be divided into 2 sub-pixel areas, in which case each sub-pixel is divided into two parts. The two parts can be controlled independently. For example, by controlling the switch through different external signals, the user on one side (left or right) of the screen can see the content, while the user on the other side cannot see it. Under the condition of being divided into two parts, the user on one side can selectively see the screen content, while the user on the other side cannot see it.

[0032] Preferably, as shown in FIG. 2 , the color sub-pixel can be further divided into three sub-pixel regions. At this time, each sub-pixel is divided into three parts, and different switch switching controls can be used to achieve privacy protection in two directions. That is, the left, right and middle parts of the screen can be controlled separately, so that users on the left and right sides of the screen can see different content, or at least users on one side cannot see the content seen by users on the other side.

[0033] The switch control unit at least includes a MUX module; one end of the MUX module is connected to the sub-pixel area, and the other end of the MUX module is connected to the external control source; the switch of the MUX module is controlled by the first control signal and / or the second control signal to achieve pixel control.

[0034] It should be noted that, in this embodiment, each switch control unit can be implemented by a MUX multi-way selection circuit module. For example, three sub-pixel regions in a color sub-pixel are connected to the MUX multi-way selection circuit module in multiple ways so as to independently control each sub-pixel region. The MUX multi-way selection circuit module allows one or more outputs to be selected from multiple inputs, and different sub-pixel regions can be selectively activated or deactivated.

[0035] In this embodiment, the driving unit is used to provide the necessary operating voltage and operating current to drive the liquid crystal or other display elements to control the brightness and color of each pixel. For example, the driving unit can be implemented by a thin film transistor driver, a source driver, a gate driver, etc., but is not limited thereto.

[0036] In this embodiment, the external control source can be implemented by the vehicle's central control unit or the microcontroller of the in-vehicle entertainment system, such as a display controller, which is used to manage the hardware and software components of the display panel, and it can generate control signals to control the TFT switch; it can also be other input devices such as light sensors, proximity sensors or touch screens, which generate control signals based on environmental conditions or user input.

[0037] When the color sub-pixel is divided into three sub-pixel regions, namely L-TFT, M-TFT and R-TFT, the external control source is responsible for outputting a first control signal, such as CONTROL 1, and a second control signal, such as CONTROL 2, which are used to control the opening and closing of L-TFT and R-TFT, thereby realizing the control of each part of the sub-pixel region. Preferably, the MUX multi-way selection circuit module can be set to activate M-TFT by default when outputting, and CONTROL 1 and CONTROL2 signals control L-TFT and R-TFT respectively, without limitation thereto.

[0038] In the present application, the other end of the driving unit is connected to the external control source, and is used to receive the clock synchronization signal and the inverted clock synchronization signal output by the external control source.

[0039] It should be noted that the clock synchronization signal is the driving unit that works normally to ensure that the data is transmitted to the correct pixel at the correct time and to complete the switching control. Preferably, the clock synchronization signal can be a square wave signal, and its frequency determines the display refresh rate. For example, a 60Hz clock synchronization signal means 60 refreshes per second, which provides a smooth visual experience for the user. In addition, the clock synchronization signal can also be used to synchronize data transmission to ensure that the data of each pixel is updated at the correct position on the scan line.

[0040] The inverted clock synchronization signal is usually opposite to the clock synchronization signal, that is, when the clock synchronization signal is high, the inverted clock synchronization signal is low, and vice versa. The inverted clock synchronization signal can be used to control the charging and discharging process of the pixel. For example, in an LCD display, the pixel is charged at the rising edge of the clock synchronization signal and discharged at the falling edge of the inverted clock synchronization signal. The inverted clock synchronization signal can also be used to reduce power supply noise and electromagnetic interference and help balance the flow of current.

[0041] Furthermore, any of the sub-pixel regions includes an electrode region; wherein each of the electrode regions is independent of each other; and each of the electrode regions is respectively connected to the first end of the switch control unit.

[0042] It should be noted that in this embodiment, the color sub-pixels can be divided into 2 or 3 or more sub-pixel areas by dividing the electrode unit in any color sub-pixel into a corresponding number of electrode areas, so as to achieve independent control of the activation or deactivation of each sub-pixel area, thereby further achieving flexible settings required for anti-peeping.

[0043] In summary, the embodiments of the present application can achieve a flexible and adjustable anti-peeping display effect according to the user's viewing direction or the requirements of the application scenario by independently controlling the display state of each sub-pixel area.

[0044] Embodiment 2: As shown in FIG. 3 , in order to solve the above technical problems, the present application also proposes a pixel design control method, which is applied to any of the above pixel design control systems, and the system includes: S100: Divide the color sub-pixel into a preset number of sub-pixel regions.

[0045] It should be noted that the division of sub-pixel areas can be adjusted according to actual needs. For example, the number and distribution of sub-pixel areas can be adjusted according to different display effects or anti-peeping requirements. Preferably, in this embodiment, the three RGB color sub-pixels can be evenly divided into three sub-pixel areas, namely the left area, the middle area and the right area, but are not limited thereto.

[0046] In the embodiment of the present application, the step S100 is specifically: The electrode unit in any color sub-pixel is divided according to a preset number of sub-pixel regions to obtain a preset number of electrode regions; wherein each of the electrode regions corresponds to a sub-pixel region and is independent of each other.

[0047] Preferably, it is assumed that a color sub-pixel is divided into three sub-pixel regions, namely a left region, a middle region and a right region. Each sub-pixel region corresponds to an electrode region, namely a left electrode region, a middle electrode region and a right electrode region.

[0048] When the external control source outputs the first control signal and the second control signal, the left electrode region, the middle electrode region and the right electrode region can be activated or deactivated as needed, thereby achieving different display effects.

[0049] For example, when the first control signal activates the middle electrode area and the second control signal turns off the left and right electrode areas, the user can see the content in the middle area of ​​the screen, while the left and right areas cannot see the screen content, thereby achieving a good anti-peeping effect.

[0050] According to the above principle, in other embodiments, the activation or deactivation control of different electrode areas can be adjusted to achieve an anti-peeping effect, or the anti-peeping position can be flexibly customized according to the viewing direction of different users.

[0051] S200: Determine the distribution position and proportion of the first display side and the second display side according to actual display visual requirements; wherein, the first display side is obtained by adjusting the sub-pixel area by the first control signal; and the second display side is obtained by adjusting the sub-pixel area by the second control signal.

[0052] It should be noted that the first display side in this embodiment refers to the sub-pixel area of ​​normal display, which can be a continuous area or a discontinuous area. For example, a color sub-pixel is divided into three sub-pixel areas, namely the left area, the middle area and the right area. Assuming that the left area and the right area are displayed normally, and the display content cannot be seen in the middle area due to the anti-peeping effect, the first display side here is composed of the left area and the right area. The second display side refers to the sub-pixel area that controls the display to be turned off, and its technical principle is similar to that of the second display side.

[0053] In the embodiment of the present application, the distribution position and ratio of the first display side and the second display side are determined according to the actual display visual requirements, specifically: The actual display visual demand includes at least an actual demand direction; if the actual demand direction is the left side, the distribution position of the first display side is controlled to be on the left side of the distribution position of the second display side; if the actual demand direction is the right side, the distribution position of the first display side is controlled to be on the right side of the distribution position of the second display side.

[0054] It should be noted that in this embodiment, the actual display visual demand includes at least the actual demand direction. The distribution position of the first display side and the second display side can be adjusted according to the user's viewing direction or the requirements of the application scenario, that is, the anti-peeping display area can be flexibly set according to the actual scenario.

[0055] In this embodiment, the distribution positions of the first display side and the second display side are determined by actual display visual requirements, so that flexible viewing angle control can be achieved, ensuring that the content is only visible to users who are currently at a specific viewing angle.

[0056] For example, in a vehicle-mounted display system, the distribution position and proportion of the first display side and the second display side can be adjusted according to the driver's position, so that the driver can see all necessary information, while the co-pilot or other passengers may see different content or not be able to see certain content. At the same time, a rapid anti-peeping effect is also achieved, ensuring in a timely manner that sensitive information is only visible to specific users, thereby improving information security.

[0057] The actual display visual requirement also includes at least an actual anti-peeping angle; the distribution ratio of the first display side and the second display side is adjusted by the actual anti-peeping angle; wherein the distribution ratio of the first display side is obtained by the ratio of the number of sub-pixel areas included in the first display side; and the distribution ratio of the second display side is obtained by the ratio of the number of sub-pixel areas included in the second display side.

[0058] It should be noted that the actual anti-peeping angle refers to the angle range set to achieve the anti-peeping effect. Within this angle range, the user can see the displayed content; outside the angle range, the user cannot see or cannot see the displayed content clearly.

[0059] The distribution ratio of the first display side is obtained by the ratio of the number of sub-pixel regions included in the first display side. For example, if the first display side includes 2 sub-pixel regions and the second display side includes 1 sub-pixel region, the distribution ratio of the first display side is 2:1. Similarly, the distribution ratio of the second display side is obtained by the ratio of the number of sub-pixel regions included in the second display side. In the above example, the distribution ratio of the second display side is 1:2, but it is not limited thereto.

[0060] By adjusting the distribution ratio of the first display side and the second display side according to the actual anti-peeping angle, precise viewing angle control can be achieved to ensure that the content is only visible to users at a specific angle. For example, in an in-vehicle display system, the distribution ratio of the first display side and the second display side can be adjusted according to the driver's seat position and line of sight, so that the driver can see all necessary information, while the co-pilot or other passengers cannot see certain content.

[0061] Through the above functions and effects, the distribution ratio of the first display side and the second display side can be flexibly adjusted according to the actual display visual requirements, thereby achieving anti-peeping effect, flexible viewing angle control, and technical effects that adapt to different application scenarios and user needs.

[0062] Further, in the first display side, an electrode region of a sub-pixel region is activated by the first control signal; In the second display side, the electrode region of the sub-pixel region is turned off by the second control signal.

[0063] It should be noted that, in the first display side, the electrode area of ​​the sub-pixel area is activated by the first control signal. This means that when the first control signal is sent to the corresponding switch control unit, the electrode area corresponding to the first display side will be activated, allowing current to pass, thereby lighting up the corresponding sub-pixel area. The activated electrode area will cause the arrangement of the liquid crystal molecules to change, allowing light to pass through, and the display content is visible to the user on the first display side.

[0064] In the second display side, the electrode area of ​​the sub-pixel area is turned off by the second control signal. When the second control signal is sent to the corresponding switch control unit, the electrode area corresponding to the second display side will be turned off, preventing the current from passing through, thereby extinguishing the corresponding sub-pixel area. The closed electrode area will cause the arrangement of the liquid crystal molecules to remain unchanged, so that light cannot pass through, and the display content is invisible or blurred to the user on the second display side.

[0065] This method of activating and deactivating electrode areas separately through control signals enables precise control of the displayed content at different viewing angles. It allows the display system to dynamically adjust which sub-pixel areas are activated and which are deactivated based on the user's viewing position or anti-peeping requirements. In an in-vehicle display system, this can be used to protect the driver's privacy and prevent passengers from seeing sensitive information that the driver is viewing, such as navigation instructions or personal communications. In other embodiments, in public places or office environments, this technology can also prevent sensitive information from being leaked by others.

[0066] In summary, the pixel design control method in the second embodiment provides users with a better display experience and higher security through precise pixel control, realization of anti-peeping function, flexible viewing angle control, optimized display experience, improved display quality and stability, and technical effects of adapting to different application scenarios and enhancing privacy protection. The specific implementation process and principle have been introduced in detail in the first embodiment and will not be repeated in this embodiment.

[0067] Embodiment three: As shown in Figure 4, the present application also provides a display device, using a pixel design control system as described above, at least comprising: a cover plate, a lens layer, a polarizer, a pixel layer and a TFT substrate layer; the cover plate is connected to one side of the lens layer through a preset adhesive material, the other side of the lens layer is connected to one side of the pixel layer after passing through the polarizer, and the other side of the pixel layer is connected to the TFT substrate layer; wherein the lens layer includes a lens group of a preset shape; the pixel layer includes at least the several pixel units; the TFT substrate layer includes at least the driving unit and the switch control unit.

[0068] Preferably, the preset adhesive material may be an optically transparent tape for maintaining optical transparency, but is not limited thereto.

[0069] It should be noted that the lens layer added in this embodiment may be an optical lens for changing the direction of light propagation.

[0070] By changing the curvature, angle and shape of the lens, the direction of light propagation can be customized. The shape of the optical lens can be a cone, a spherical convex lens, a spherical concave lens, a cylindrical lens, etc., but are not limited thereto. By adjusting the curvature, angle and shape of the lens, the propagation path of the light can be customized so that the light is only clearly visible within a specific viewing angle range, and becomes blurred or invisible at other viewing angles.

[0071] The driving unit is responsible for providing the required voltage and current to control the brightness and color of the pixel unit, while the switch control unit is responsible for receiving external control signals and controlling the lens groups in the lens layer according to these signals.

[0072] It should be noted that the main function of the cover is to protect the lens layer from external damage, such as scratches, dust and liquid.

[0073] By connecting the preset adhesive material to the upper surface of the lens layer, the cover plate can be closely attached to the lens layer to form a protective barrier. The cover plate in this embodiment can be made of glass.

[0074] In other embodiments, the cover plate can also provide certain optical properties, such as anti-reflection or anti-glare, to improve the display effect and visibility. The polarizer can improve the viewing angle stability and color performance of the display. By controlling the polarization direction of light, the polarizer can reduce the scattering and reflection of light, thereby providing a more stable viewing angle and more realistic colors, achieving high-quality display effects.

[0075] By controlling the polarization state of light, polarizers help improve contrast, reduce reflections, enable 3D display effects, protect the liquid crystal layer, and improve viewing angles and color performance.

[0076] In other embodiments, when the external control signal indicates that the anti-peeping angle needs to be changed, the switch control unit may further adjust the position or shape of the lens group to achieve the desired anti-peeping effect, which is not limited thereto.

[0077] Further, the switch control unit at least includes a MUX module; one end of the MUX module is connected to the sub-pixel region, and the other end of the MUX module is connected to the external control source; the switch of the MUX module is controlled by the first control signal and / or the second control signal.

[0078] It should be noted that, in this embodiment, each switch control unit can be implemented by a MUX multi-way selection circuit module. For example, three sub-pixel regions in a color sub-pixel are connected to the MUX multi-way selection circuit module in multiple ways so as to independently control each sub-pixel region. The MUX multi-way selection circuit module allows one or more outputs to be selected from multiple inputs, and different sub-pixel regions can be selectively activated or deactivated.

[0079] As shown in Figure 5, it is a schematic diagram of flexible adjustment of different anti-peeping angles assuming that a color sub-pixel is divided into three sub-pixel areas, namely the left area, the middle area and the right area. The arc-shaped figure in the figure refers to the lens layer. The TFT substrate layer is refracted outside the screen through the lens layer to change the direction of light propagation. For example, the schematic diagram in the upper left corner indicates that the left area, the middle area and the right area can all see the display content normally, and the schematic diagram in the upper right corner indicates that the left area is turned off, and the middle area and the right area are displayed normally. After passing through the optical lens, users on the left and middle sides can view the screen content normally, while the anti-peeping function is activated on the right side so that users on the right cannot see the screen content.

[0080] In summary, the display device of this embodiment has a thinner and lighter structure, does not require the addition of unnecessary processes, and has a better structure and cost. It only requires the addition of a layer of optical lens and a pixel design control system that divides each sub-pixel into 2 or more independently controlled parts according to each color. Flexible controllable anti-peeping angles and controllable anti-peeping switches can be achieved.

[0081] Embodiment 4: The present application also provides a storage medium, which is a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, it implements any of the pixel design control methods described above.

[0082] It should be noted that the storage medium in this embodiment includes computer programs, configuration files, user data, etc. In the display device, the storage medium can store computer programs for controlling pixel units, lens groups, and switch control units. The storage medium must be computer readable, which means that the computer can access the data in the storage medium. For example, the storage medium can be a hard disk, a solid-state drive, a USB flash drive, an optical disk, etc. The computer program on the storage medium can be executed by a processor. In the display device, the processor can read the program on the storage medium and control the brightness and color of the pixel unit, adjust the position and shape of the lens group, and the working state of the switch control unit according to the program instructions.

[0083] Through the computer program on the storage medium, flexible viewing angle control, anti-peeping effect and technical effects that adapt to different application scenarios and user needs can be achieved.
