Description

Technical Field

[0001] This 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 Technology

[0002] Current automotive privacy protection solutions still have some significant drawbacks. For example, most passive privacy protection solutions involve adding a privacy film inside the backlight of the module or using a dotted light guide plate design to achieve privacy. However, this approach severely impacts the overall brightness of the display system. With the same number of LEDs in the backlight, adding a privacy protection solution results in significant brightness reduction. Therefore, to achieve the same brightness, more LEDs are needed, leading to more screen heat generation. Furthermore, privacy protection cannot be turned off during daytime when ambient light is sufficient, resulting in higher system power consumption. Additionally, privacy films have poor customization and limited control over the privacy angle, which can lead to poor image uniformity on large screens. While active privacy protection solutions can achieve active detection of open and closed privacy effects, most of these solutions use dual light guide plates, resulting in less than ideal privacy protection. They can only protect the entire surface and have a complex system structure. Most of these solutions use ordinary LCD cells for privacy protection, which has poor control over the privacy angle and can only protect the entire surface, resulting in poor display effects in actual applications. Furthermore, most of these solutions use dual or multiple LCD cells to construct the display panel privacy protection, which can easily lead to a thicker overall structure, contradicting the concept of lightweight and thin automotive designs, and also increasing costs.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Example 1: As shown in Figure 1, in order to solve the above-mentioned technical problems, this application provides a pixel design control system, including: The system includes several pixel units and a driving unit; wherein any pixel unit includes multiple pixels, and the pixels include multiple color sub-pixels; and also includes a switch control unit.

[0026] It should be noted that in this embodiment, each color subpixel is no longer regarded as a whole, but is physically divided into several independently controlled areas. This allows for regional control of the screen display content, so that only users at specific angles can see the full content, while users at other angles can hardly see the content at all. This greatly enhances privacy protection against peeping. 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 remain normally displayed.

[0027] For example, in an in-vehicle display system, the privacy screen can be turned off when it is within the driver's line of sight, but turned on when it is within the line of sight of the passenger or rear seat. This way, the passenger's screen content cannot be seen from the driver's viewing angle, thus preventing the information on the passenger's screen from distracting the driver and causing a driving safety accident.

[0028] In this embodiment, the pixel design control system specifically comprises: Each of the aforementioned color sub-pixels is composed of a plurality of sub-pixel regions; each sub-pixel region is connected to a first terminal of a switch control unit, a second terminal of the switch control unit is connected to a first terminal of a drive unit, and a third terminal 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 number of drive units and switch control units is the same as the number of color sub-pixels, and each switch control unit is connected to only one sub-pixel region in a color sub-pixel; the first control signal is used to independently control the activation of any one of the aforementioned sub-pixel regions; the second control signal is used to independently control the deactivation of any one of the aforementioned sub-pixel regions.

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

[0030] In this embodiment, each sub-pixel, which was originally a single pixel, such as a red sub-pixel, a green sub-pixel, or a blue sub-pixel, is physically or logically divided into smaller regions, which are then individually controlled by each switch control unit.

[0031] Preferably, the color subpixel can be divided into two subpixel regions, in which case each subpixel is divided into two parts. These two parts can be controlled independently. For example, by controlling a switch with different external signals, the content can be seen by a user on one side of the screen (left or right), while the content cannot be seen by a user on the other side. Under the condition of being divided into two parts, the screen content can be selectively shown to a user on one side, while the content cannot be seen by a user on the other side.

[0032] Preferably, as shown in Figure 2, the color subpixel can be further divided into 3 subpixel regions. In this case, each subpixel is divided into three parts, which can be combined with different switches to switch controls, achieving 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 one user cannot see the content seen by the user on the other side.

[0033] The switch control unit includes at least 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, thereby realizing the control of the pixel.

[0034] It should be noted that in this embodiment, each switch control unit can be implemented using a MUX multiplexing circuit module. For example, three sub-pixel regions in a color sub-pixel can be connected to the MUX multiplexing circuit module separately to independently control each sub-pixel region. The MUX multiplexing circuit module allows selection of one or more outputs from multiple inputs, selectively activating or deactivating different sub-pixel regions.

[0035] In this embodiment, the driving unit is used to provide the necessary operating voltage and 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 using a thin-film transistor driver, a source driver, and a gate driver, etc., and 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 manages the hardware and software components of the display panel and can generate control signals to control the TFT switch; or it can be other input devices such as a light sensor, proximity sensor or touch screen, which generate control signals according to environmental conditions or user input.

[0037] When a color subpixel is divided into three subpixel regions, namely L-TFT, M-TFT, and R-TFT, an external control source is responsible for outputting a first control signal, such as CONTROL 1, and a second control signal, such as CONTROL 2. These signals are used to control the on and off states of L-TFT and R-TFT, thereby controlling each subpixel region. Preferably, the MUX multiplexer circuit module output can be set to have M-TFT activated by default, while CONTROL 1 and CONTROL 2 signals control L-TFT and R-TFT respectively, but this is not limited to these settings.

[0038] In this application, the other end of the drive unit is connected to the external control source 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 essential for the normal operation of the drive unit, ensuring that data is transmitted to the correct pixels at the correct time and for controlling the switching. Preferably, the clock synchronization signal can be a square wave signal, the frequency of which determines the display refresh rate. For example, a 60Hz clock synchronization signal means refreshing 60 times per second, providing users with a smooth visual experience. Additionally, the clock synchronization signal can also be used to synchronize data transmission, ensuring that the data for each pixel is updated at the correct position on the scan line.

[0040] An inverting clock synchronization signal is typically the opposite of the clock synchronization signal; that is, when the clock synchronization signal is high, the inverting clock synchronization signal is low, and vice versa. Inverting clock synchronization signals can be used to control the charging and discharging processes of pixels. For example, in an LCD display, pixels are charged on the rising edge of the clock synchronization signal and discharged on the falling edge of the inverting clock synchronization signal. Inverting clock synchronization signals can also be used to reduce power supply noise and electromagnetic interference, and help balance current flow.

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

[0042] It should be noted that in this embodiment, the color subpixel can be divided into 2, 3 or more subpixel regions by dividing the electrode unit in any color subpixel into a corresponding number of electrode regions, thereby enabling independent control of the activation or deactivation of each subpixel region, and further enabling flexible settings to meet the needs of privacy protection.

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

[0044] Example 2: As shown in Figure 3, in order to solve the above-mentioned technical problems, this application also proposes a pixel design control method, applied to any of the pixel design control systems described above, the system comprising: S100: Divide the color sub-pixel into a preset number of sub-pixel regions.

[0045] It should be noted that the division of subpixel regions can be adjusted according to actual needs. For example, the number and distribution of subpixel regions can be adjusted according to different display effects or privacy requirements. Preferably, in this embodiment, the RGB color subpixels can be evenly divided into three subpixel regions: a left region, a middle region, and a right region, but this is not limited to these.

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

[0047] Preferably, it is assumed that a color sub-pixel is divided into 3 sub-pixel regions, namely the left region, the middle region, and the right region. Each sub-pixel region corresponds to an electrode region, namely the left electrode region, the middle electrode region, and the right electrode region.

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

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

[0050] Based on the above principle, in other embodiments, the activation or deactivation control of different electrode areas can be adjusted to achieve the privacy protection effect, or the privacy protection position can be flexibly customized according to the viewing direction of different users.

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

[0052] It should be noted that in this embodiment, the first display side refers to the normally displayed sub-pixel area, which can be a continuous or non-contiguous area. For example, if a color sub-pixel is divided into three sub-pixel areas—the left, middle, and right areas—and assuming the left and right areas are normally displayed, while the middle area is not visible due to privacy protection, then the first display side here is composed of the left and right areas. 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 this embodiment of the application, determining the distribution position and ratio of the first display side and the second display side according to actual display visual requirements specifically involves: The actual display visual requirements include at least the actual requirement direction; if the actual requirement direction is to the left, the distribution position of the first display side is controlled to the left of the distribution position of the second display side; if the actual requirement direction is to the right, the distribution position of the first display side is controlled to the right of the distribution position of the second display side.

[0054] It should be noted that the actual visual display requirements in this embodiment include at least the actual viewing direction. Therefore, the distribution positions 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. In other words, the privacy display area can be flexibly set according to the actual scenario.

[0055] This embodiment determines the distribution positions of the first and second display sides based on actual visual display needs, enabling flexible viewing angle control and ensuring that the content is only visible to the user at the current specific viewing angle.

[0056] For example, in an in-vehicle display system, the distribution and ratio of the first and second display sides can be adjusted according to the driver's position, so that the driver can see all the necessary information, while the front passenger or other passengers may see different content or not see certain content. At the same time, it also achieves a quick anti-peeping effect, ensuring that sensitive information is only visible to specific users, thereby improving information security.

[0057] The actual display visual requirements also include at least the actual privacy angle; the distribution ratio of the first display side and the second display side is adjusted by the actual privacy angle; wherein, the distribution ratio of the first display side is obtained by the ratio of the number of sub-pixel regions contained in the first display side; the distribution ratio of the second display side is obtained by the ratio of the number of sub-pixel regions contained in the second display side.

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

[0059] The distribution ratio of the first display side is determined by the ratio of the number of sub-pixel regions contained within it. For example, if the first display side contains two sub-pixel regions and the second display side contains one sub-pixel region, the distribution ratio of the first display side is 2:1. Similarly, the distribution ratio of the second display side is determined by the ratio of the number of sub-pixel regions contained within it. In the example above, the distribution ratio of the second display side is 1:2, but this is not an isolated case.

[0060] By adjusting the distribution ratio of the first and second display sides according to the actual privacy angle, precise viewing angle control can be achieved, ensuring that content is only visible to users at a specific angle. For example, in an in-vehicle display system, the distribution ratio of the first and second display sides can be adjusted according to the driver's seat position and line of sight, allowing the driver to see all necessary information while preventing the front passenger or other passengers from seeing 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 needs, thereby achieving anti-peeping effect, flexible viewing angle control, and technical effects that adapt to different application scenarios and user needs.

[0062] Furthermore, on the first display side, the electrode region of the sub-pixel region is activated by the first control signal; On the second display side, the electrode area of ​​the sub-pixel region is turned off by the second control signal.

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

[0064] On the second display side, the electrode area of ​​the sub-pixel region is turned off via a 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 is turned off, preventing current from flowing and thus extinguishing the corresponding sub-pixel area. The closed electrode area causes the liquid crystal molecules to remain in their original alignment, preventing light from passing through, making the displayed content invisible or blurry to the user on the second display side.

[0065] This method of activating and deactivating electrode regions separately via control signals enables precise control of the displayed content from different viewing angles. It allows the display system to dynamically adjust which sub-pixel regions are active and which are deactivated based on the user's viewing position or privacy requirements. In automotive display systems, this can be used to protect driver privacy and prevent passengers from seeing sensitive information 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 spied on and leaked.

[0066] In summary, the pixel design control method in Embodiment 2 provides users with a better display experience and higher security through precise pixel control, the implementation of anti-peeping functionality, flexible viewing angle control, optimized display experience, improved display quality and stability, and the technical effects of adapting to different application scenarios and enhancing privacy protection. The specific implementation process and principles have been detailed in Embodiment 1 and will not be repeated in this embodiment.

[0067] Example 3: As shown in Figure 4, this application also provides a display device that applies a pixel design control system as described above, comprising at least: 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 via 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 plurality of pixel units; and the TFT substrate layer includes at least the driving unit and the switching control unit.

[0068] Preferably, the pre-set adhesive material can be an optically transparent tape to maintain optical transparency, but it is not limited to this.

[0069] It should be noted that the lens layer added in this embodiment can be an optical lens, used to change the direction of light propagation.

[0070] By changing the curvature, angle, and shape of a lens, the direction of light propagation can be customized. The shape and construction of an optical lens can be conical, convex spherical, concave spherical, cylindrical, etc., and is not limited to these. By adjusting the curvature, angle, and shape of the lens, the propagation path of light can be customized, so that the light is clearly visible only within a specific viewing angle range, while becoming blurry or invisible at other viewing angles.

[0071] The drive unit is responsible for providing the necessary voltage and current to control the brightness and color of the pixel units. The switch control unit is responsible for receiving external control signals and controlling the lens group in the lens layer according to these signals.

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

[0073] By connecting the cover plate to the upper surface of the lens layer using a pre-set adhesive material, the cover plate can be tightly adhered to the lens layer, forming a protective barrier. In this embodiment, the cover plate can be made of glass.

[0074] In other embodiments, the cover plate may also provide certain optical properties, such as anti-reflection or anti-glare, thereby improving display quality and visibility. Polarizers can improve the viewing angle stability and color performance of the display. By controlling the polarization direction of light, polarizers can reduce light scattering and reflection, thus 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 reflection, achieve 3D display effects, protect the liquid crystal layer, and improve viewing angle and color performance.

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

[0077] Furthermore, the switch control unit includes at least 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 using a MUX multiplexing circuit module. For example, three sub-pixel regions in a color sub-pixel can be connected to the MUX multiplexing circuit module separately to independently control each sub-pixel region. The MUX multiplexing circuit module allows selection of one or more outputs from multiple inputs, selectively activating or deactivating different sub-pixel regions.

[0079] As shown in Figure 5, this diagram illustrates how different privacy angles can be flexibly adjusted when a color subpixel is divided into three subpixel regions: the left region, the middle region, and the right region. The arc-shaped graphic in the diagram refers to the lens layer. The TFT substrate layer, through the lens layer, refracts light outside the screen, which can change the direction of light propagation. For example, the diagram in the upper left corner shows that the left, middle, and right regions can all see the displayed content normally. The diagram in the upper right corner shows that the left region is turned off, while the middle and right regions are displayed normally. Through the optical lens, users on the left and middle sides can normally view the screen content, while the privacy function is activated on the right side, preventing users on the right side from seeing the screen content.

[0080] In summary, the display device in this embodiment has a thinner and lighter structure, does not require additional processes, and has a better structure and cost. It only requires the addition of an optical lens and a pixel design control system that divides each sub-pixel into two or more independently controlled parts according to each color, so that flexible privacy angle controllability and privacy switch controllability can be achieved.

[0081] Example 4: This application also provides a storage medium, which is a type of computer-readable storage medium, having stored thereon a computer program that, when executed by a processor, implements the pixel design control method as 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 used to control pixel units, lens groups, and switch control units. The storage medium must be computer-readable, meaning that a computer can access the data in the storage medium. For example, the storage medium can be a hard disk, solid-state drive, USB flash drive, 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 units, adjust the position and shape of the lens group, and control the operating state of the switch control unit according to the program instructions.

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

[0084] For example, in an in-vehicle display system, a computer program can dynamically adjust the brightness and color of pixel units, as well as the position and shape of lens groups, based on the driver's position and line of sight. This allows the driver to see all necessary information, while the front passenger or other passengers may see different content or be unable to see certain content. Through these functions and effects, the storage medium provides a flexible, efficient, and customizable control method for display devices, thereby improving the user experience and the reliability of the equipment.

[0085] The processor can be a central processing unit (CPU), or it can be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor can be a microprocessor or any conventional processor. The memory is used to store the operating system, application programs, bootloader, data, and other programs, such as the program code of the computer program. The memory can also be used to temporarily store data that has been output or will be output.

[0086] In the several embodiments provided in this application, it will be understood that each block in the flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions marked in the blocks may occur in a different order than those shown in the figures. For example, two consecutive blocks may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved.
