DETAILED DESCRIPTION OF THE INVENTION

[0018] The embodiments and features of the embodiments in the present disclosure may be combined with each other as long as they are not inconsistent. The present disclosure will be described in detail below by way of examples with reference to the drawings.

[0019] In order to enable those skilled in the art to better understand the solutions of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part, not all, of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without any creative work should fall within the protection scope of the present disclosure.

[0020] It should be noted that terms such as "first," "second," etc. in the specification, claims, and drawings of the present disclosure are not necessarily used to describe a specific order or chronology, but are used to distinguish between similar objects. It should be understood that data used in this manner may be interchanged as appropriate to enable the embodiments of the present disclosure described herein to be implemented. Furthermore, the terms "comprise" and "have" and any variations thereof are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the explicitly shown steps or units, but may include other steps or units that are not explicitly shown or inherent in the process, method, product, or apparatus.

[0021] For the sake of convenience, some nouns or terms related to the embodiments of the present disclosure will be explained below.

[0022] TCON, short for display control chip, refers to the main control chip located on the display logic board that controls the driving and touch functions of the display screen. The TCON receives and decodes display control signals. It receives pixel data and timing control signals from the motherboard or display controller, analyzes them, and generates pixel data and control signals to drive the display screen. The TCON drives the display screen and provides pixel data and timing control signals to display images. Based on the analyzed display control signals, the TCON generates and transmits RGB, QVGA, or other pixel data signals, HSYNC and VSYNC row synchronization signals, and other driving and timing control signals to accurately display images on the display screen. The TCON supports touchscreen driving and detection. In addition to generating pixel data and control signals for the display screen, it also scans, decodes, and processes them for the touchscreen, enabling the touchscreen to respond properly to user touches. This primarily includes functions such as scanning capacitance data for capacitive touchscreens and bus conversion. TCONs can be customized based on specific screen technologies and parameters, or designed using general-purpose chips. The main screen technologies involved include TFT-LCD, OLED, and capacitive touch screen, and TCONs for different technologies have certain differences.

[0023] A touch IC, also known as a touch chip or touch integrated circuit, is an electronic chip that realizes touch detection. Touch ICs are a key component in ensuring touchscreens and touch devices respond correctly to user touches. Touch ICs integrate related technologies, such as capacitance, infrared, and surface acoustic waves, to detect the contact between a user's finger or touch tool and a touchscreen or device and generate corresponding electrical signals to locate the touch. By analyzing the detection signals, touch ICs estimate the specific location and continuous touch trajectory of the user's touch, helping touch application programs accurately locate touch points, thereby achieving accurate touch responses and providing a standardized output interface. Multi-touch technology, which offers high usability, is gradually becoming more common in mainstream products. To meet multi-touch requirements, touch ICs must simultaneously detect and accurately locate multiple touch points. Some touch ICs also support the identification and classification of touch actions with different forces and durations, or intuitive gesture recognition.

[0024] A touch sensor is a device that detects user touch input and is primarily used to realize the touch function of touchscreens and touch devices. Common touch sensors include capacitive touch sensors, resistive touch sensors, surface acoustic wave touch sensors, and infrared touch sensors. Capacitive touch sensors use variable capacitors to form a capacitance network and detect changes in capacitance caused by a user's touch. They have the advantages of fast response and low cost, but the disadvantages of low durability. Resistive touch sensors form a grid circuit on the display screen and detect changes in the circuit's resistance caused by a user's touch. They have the advantages of high durability and resistance to damage, but the disadvantages of high cost and slow response. Surface acoustic wave touch sensors generate high-frequency acoustic waves around the display screen, and the reflection of the acoustic waves caused by the user's touch is captured by a detector. They have the advantages of high durability and resistance to interference, but the disadvantages of high cost, large volume, and slightly lower sensitivity than capacitive screens. Infrared touch sensors have infrared emitters located around the display, and the interruption of the infrared light by the user's touch is detected by an infrared detector. They have the advantages of being highly durable and less susceptible to environmental influences, but the disadvantages are high cost, large space requirements, and limited operating temperature.

[0025] A motherboard controller is an electronic component on a motherboard that provides basic control functions for the system.

[0026] A video card, also known as a graphics card or display card, is an important component in a computer system that displays and processes images. Its primary function is to process image data. A video card has a dedicated image processing unit that performs various image processing operations on images, such as sampling, compression, decoding, coloring, and rendering, enabling image display and real-time rendering. The computing power of the image processing unit directly affects the display effect and gaming experience. A video card can output images to a display screen. A video card supports interfaces for different display standards, such as VGA, DVI, HDMI (registered trademark), and DisplayPort, and can output processed image data through these interfaces to display devices such as external displays and televisions for image display. Different video cards support different display technologies, such as 2D or 3D images, resolutions, pixel rates, and refresh rates. To achieve ideal display effects, the display and video card must support the same display technology standard. Because a video card has an independent image processing unit, it can process complex image-related operations independently, thereby sharing the load of the central processing unit and improving the overall system performance.

[0027] As described in the background art, image delay in the prior art affects user experience. To solve the above problem, embodiments of the present disclosure provide a display system and an electronic device.

[0028] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the technical means in the embodiments of the present invention will be described clearly and comprehensively with reference to the drawings in the embodiments of the present invention.

[0029] This embodiment provides a display system. The term "module" used below can realize a combination of software and / or hardware for a given function. The device described in the following embodiment is preferably realized in software, but may also be realized in hardware or a combination of software and hardware.

[0030] A display system according to an embodiment of the present disclosure will be described below.

[0031] 1 is a schematic diagram of a display system according to an embodiment of the present disclosure. As shown in FIG. 1, the device includes a control unit 10 and a display unit 20. The control unit 10 transmits control commands. Specifically, the control commands sent from the control unit may include a screen update control command, a brightness control command, a color setting command, a display area setting command, a display mode setting command, and a parameter query command. The screen update control command controls the refresh frequency and refresh mode of the display. These commands can set parameters such as the refresh interval, refresh direction (vertical refresh or horizontal refresh), and scanning area range, thereby realizing customized display update policies, improving display performance, and reducing display power consumption. The brightness control command controls the brightness level and contrast of the display. Different brightness settings correspond to different light source powers, and these commands can flexibly adjust the display brightness according to changes in ambient light or user experience to achieve optimal visual display effects. The color setting command sets the hue and saturation of each color channel (the three primary colors: red, green, and blue) of the display. These commands enable flexible adjustment of the display's color output capabilities, achieving diverse color display effects, and improving the user experience. The display area setting command sets the size and position of the content actually displayed on the display. This command defines the upper left and lower right points of the display area, controlling the range of the box corresponding to the display content and achieving customized display ratios and layouts. The display mode setting command sets the display mode of the display, such as monochrome, color, or high-color. Different display modes correspond to different pixel format color spaces, and this command allows the display mode to be flexibly switched to meet various user display needs. The parameter query command queries important display parameters of the display, such as the number of colors, color depth, and pixel density. By actively querying these important parameters, the system can determine whether the display's current display capabilities meet or exceed design requirements and make timely adjustments. This is crucial for optimizing display effects and performance.

[0032] The display unit 20, which is directly communicatively connected to the control unit 10, includes a storage module 21 that stores target display information. The display unit 20 receives the control command transmitted from the control unit 10, and acquires and displays the target display information stored in the storage module 21 based on the control command.

[0033] Specifically, the display unit may be a liquid crystal display, an organic electroluminescent display, an electric disk display, or a touch display. Liquid crystal displays (LCDs) are the most common and widely used display type. They display images by controlling the arrangement of liquid crystal molecules and are characterized by their thinness, lightness, and low energy consumption. Major LCD resolutions include WVGA, QVGA, VGA, WVGA, and FWVGA. Displays such as organic light-emitting diode displays (OLEDs) display images by emitting light from an organic charge transport layer, offering advantages such as high contrast, excellent response time, and a wide viewing angle. OLED displays are primarily used in high-end mobile phones and tablet computers. Displays such as electronic ink displays (E-ink displays) display images by controlling the movement of charges in an ink separation layer. They offer advantages such as high contrast and low energy consumption, but suffer from a low refresh rate and are currently primarily used in e-books. Compared to conventional display screens, touch screens support touch input of displayed content and are generally combined with a touch panel using one of the above display technologies. Specific touch panel technologies include resistive, capacitive, infrared, etc. Touch screens are widely used in display design and are used in mobile phones, tablet computers, mobile phones, etc. The memory module may be a flash memory.

[0034] According to this embodiment, there is provided a display system including a control unit that transmits control commands, and a display unit that includes a storage module that stores target display information and is directly connected to the control unit so as to be able to communicate with the control unit, wherein the display unit receives the control commands transmitted from the control unit, and retrieves and displays the target display information stored in the storage module based on the control commands. By having the control unit communicate directly with the display unit, the display unit can directly call up and display the stored information in the storage module, allowing the display system to output data without relying on a video card and resolving the problem of image delay affecting the user experience.

[0035] 2, in a specific implementation, the display system further includes a touch unit 30, which is communicatively connected to the control unit 10, for receiving touch signals, converting the touch signals into touch information including at least touch position information, and transmitting the touch information to the control unit 10. The system is further applied to the field of touch display.

[0036] Specifically, the display unit is responsible for actually displaying images and content. It typically uses technologies such as liquid crystal display (LCD) or organic electroluminescence display (OLED) to display images by controlling pixels, light, or liquid crystals. The display refreshes images and updates the display according to the instructions of the motherboard controller. The touch unit is attached to the front or back of the display and detects user touch input and converts it into an electrical signal. Currently, mainstream touch panel technologies include resistive, capacitive, and infrared. These detect touch by changing resistance or capacitance or absorbing infrared light, respectively, and send the detection signal to the motherboard controller for processing. The motherboard controller not only controls the display, but also receives and interprets touch signals from the touch panel and generates corresponding system responses. For example, when a user's touch point is detected moving or released on the touch screen, the motherboard controller identifies the corresponding touch point location and its coordinate information, and drives the display to update the content in response to the user's operation. The motherboard also needs to reset, calibrate, and optimize the parameters of the touch system to ensure its normal operation.

[0037] The control unit of the present disclosure receives the touch information and generates the control command based on the touch information, and the system can also generate the control command quickly.

[0038] Specifically, after receiving the coordinate information of the touch point, the motherboard controller must determine the display content or control corresponding to the touch point. If a corresponding control is identified, its identification information is also sent in bulk. Based on the identified control information, the motherboard controller generates and operates a corresponding control command. For example, for a text box or list box, the command may be a command to set a cursor position or select a character. For a button, the command may be a command to simulate pressing or releasing a button. For a form control, the command may be a command to input a character or select an option. For a screen object, the command may be a command to modify attributes such as the object position, size, or color. The motherboard controller then transmits the generated control command to other components, causing the other components to execute the command to complete the device operation required for human-computer interaction. By repeating the above steps, the system continues to generate and execute related control commands based on subsequent user touch operations, responding to user interactions in real time and creating a richer user experience.

[0039] The display unit further displays the target display information on a target area of ​​the display unit according to the control command, the target area being a projection area on the display unit of the touch area corresponding to the touch position information, so that the system can accurately position and display the touch area.

[0040] Specifically, the touch unit detects the user's touch position information, converts it into an electrical signal, and then converts it into coordinate information of the touch point and transmits it to the motherboard controller via an interface. Generally, the touch panel is located above the display panel, and this method is simple and practical and is applied to ordinary touch screen displays. The touch panel is located on the surface of the display screen, and the user can directly sense the content and current display state of the display screen by touching a position on the panel, realizing a direct correspondence between vision and touch, and making the user experience more intuitive and natural.

[0041] In some embodiments, the display unit further updates historical display information in the target area of ​​the display unit, and displays the target display information in the target area of ​​the display unit. The system can further realize updating of historical display information.

[0042] Specifically, for example, the historical display information can be updated by modifying pixel values ​​to update the text content and image display. The display is updated by setting the RGB values ​​of each pixel point. The specified display area is refreshed by modifying the graphic memory data. The area refresh display is realized in the display controller by pushing the data into the graphic memory. The overlapping relationship of the display objects is controlled by modifying attributes such as the display level and transparency. The display effect is updated by setting related parameters in the display controller.

[0043] In some embodiments, displaying the target display information in the target area of ​​the display unit based on the control command further includes updating a number in the storage module of the target display information.

[0044] Specifically, the MCU receives the positioning signal from the touch IC and notifies the TCON that the position, library number and corresponding color information need to be updated. The TCON can directly call and display a local update block (which can be customized and is different from the content of the operation itself) from flash instead of the current update position, and also update the library index number.

[0045] As an optional technical means, the display unit includes a logic board that acquires the target display information stored in the storage module, receives the control command, and converts the control command into a drive signal, and a display module that is communicatively connected to the logic board, receives the drive signal, and displays the target display information stored in the storage module based on the drive signal. The system further subdivides the internal configuration of the display unit.

[0046] Specifically, the logic board, i.e., the screen driver board, receives and analyzes image data including color information (RGB values) of pixel points. It processes the data and solves problems such as pixel mapping and backplane normalization. It then divides the image into pixel regions with multiple rows and columns corresponding to the matrix structure of the actual display panel. It also performs mapping for the pixels. Based on the matrix information and pixel mapping, it generates RGB values ​​for each pixel point and outputs them as pixel display data. Based on related control signals, it updates the RGB pixel data at appropriate times and controls the display panel to refresh the displayed image content. The display panel updates the display screen according to changes in the received RGB data. Constantly refreshing the RGB data and controlling the display panel ensures that the display always displays the latest image content, achieving real-time image display updates.

[0047] In an optional technical means, the control unit further sets a communication protocol between the logic board and the control unit so as to directly connect the control unit and the display unit for communication, and the system can further quickly realize the direct communication connection between the control unit and the display unit.

[0048] Specifically, setting the communication protocol between the logic board and the control unit mainly involves setting the communication method, describing the communication protocol, setting communication commands, setting response signals, and error handling. Communication methods mainly include serial communication (SPI, I2C) and parallel communication (channels divided by time series). Serial communication is simple and easy to use, but has low data transmission efficiency, while parallel communication is the opposite. The communication protocol description indicates the protocol version, communication rate, maximum packet size, and end signal for both parties. This ensures that both parties can quickly understand and use the standard communication method. All commands used to operate the screen driver board should be included in the protocol, accompanied by parameters and descriptions. These include commands for pixel data transmission, display area refresh, parameter setting, etc. After ensuring that the command is executed correctly, the screen driver board should generate and confirm the relevant response signal. System abnormalities due to incorrect command transmission or communication interruption should be avoided. All possible error situations that may occur during communication should be considered, and corresponding handling measures should be taken to ensure system stability. Error types, error codes, and handling methods are specified in the protocol.

[0049] In yet another optional technical means, the target display information includes at least one of virtual keyboard information, cursor information, and temperature information of the control unit, which can further improve user experience.

[0050] Specifically, in practical applications, when a user uses a touchscreen electronic device, a virtual keyboard corresponding to the size of the screen, i.e., the virtual keyboard information, is always displayed. In addition, the cursor information may help the user clarify the touch position. The temperature information of the display control unit can further help the user understand the usage status of the electronic device.

[0051] An embodiment of the present invention provides an electronic device including a processor, a memory, and a program stored in the memory and executable on the processor. The device according to this specification may be a server, a PC, a PAD, a mobile phone, etc.
