[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present disclosure.

[0024] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate for the embodiments of the present disclosure described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products, or apparatus.

[0025] For ease of description, some nouns or terms involved in the embodiments of the present disclosure are explained below:

[0026] TCON: The display control chip, abbreviated as TCON, is the main control chip located on the display logic board that controls and drives the display screen or touchscreen. The TCON receives and decodes display control signals. It receives pixel data and timing control signals from the motherboard or display controller, parses them, and generates pixel data and control signals for driving the display screen. The TCON drives the display screen, providing pixel data and timing control signals for image display. Based on the parsed display control signals, it generates and issues RGB, QVGA, or other pixel data signals, horizontal synchronization signals HSYNC and VSYNC, and other drive timing control signals to ensure the display screen displays images correctly. The TCON supports touchscreen driving and detection. It not only generates pixel data and control signals for the display screen, but also scans, decodes, and processes the touchscreen to ensure proper touchscreen response. This primarily includes functions such as capacitive data scanning and bus conversion for capacitive touchscreens. The TCON can be customized based on specific screen technology and parameters or designed using a general-purpose chip. The main screen technologies involved include TFT-LCD, OLED, capacitive touch screen, etc. The TCON corresponding to different technologies will have certain differences.

[0027] Touch IC: A touch IC, also known as a touch chip or touch integrated circuit, is an electronic chip that implements touch detection. It is a key component for touch screens and touch devices to properly respond to user touch. It detects user touch. Touch ICs integrate detectors using technologies such as capacitive, infrared, and surface acoustic wave (SAW) to detect contact between a user's finger or touch tool and the touch screen or device and generate corresponding electrical signals. This helps locate the touch. By analyzing the detection signals, the touch IC can infer the specific touch location and continuous touch trajectory, enabling touch applications to correctly locate the touch point and achieve precise touch response. It also provides a standardized output interface. Multi-touch, with improved operability, is gradually being adopted in mainstream products. Touch ICs need to simultaneously detect multiple user touch points and accurately locate them to meet multi-touch requirements. In addition, some touch ICs support recognition and classification of touch actions based on different force levels and durations, as well as intuitive gesture recognition.

[0028] Touch sensor: A touch sensor is a device used to detect user tactile input and is primarily used to implement touch functionality on touch screens and touch devices. Common touch sensors include capacitive touch sensors, resistive touch sensors, surface acoustic wave (SAW) touch sensors, and infrared touch sensors. Capacitive touch sensors use varactors to form a capacitor network. User touch changes the capacitance value, which is detected. Their advantages are fast response and low cost; their disadvantages are poor durability. Resistive touch sensors form a grid circuit on the display. User touch changes the resistance value, which is detected. Their advantages are high durability and resistance to damage; their disadvantages are high cost and slow response. Surface acoustic wave (SAW) touch sensors emit high-frequency sound waves around the display. User touch causes the sound waves to be reflected and detected by the detector. Their advantages are high durability and resistance to interference; their disadvantages are high cost, large size, and slightly lower sensitivity than capacitive touch screens. Infrared touch sensors use infrared ray emitters or transmitters around the display. User touch blocks the infrared rays, which are detected by the infrared detector. Their advantages are high durability and resistance to environmental influences; their disadvantages are high cost, large footprint, and limited operating temperature.

[0029] Mainboard controller: The mainboard controller refers to the electronic component on the motherboard that implements the basic control functions of the system.

[0030] Graphics cards: A graphics card, also known as a graphics card or display card, is a crucial device used by computer systems to display and process images. Its primary function is to process image data. A graphics card has a dedicated image processing unit (GPU) that performs various image processing operations, including sampling, compression, decoding, shading, and rendering, enabling image display and real-time rendering. The computing power of the GPU directly impacts display quality and gaming experience. Graphics cards output images to the display screen. Graphics cards support interfaces with various display standards, such as VGA, DVI, HDMI, and Display Port. These interfaces can output processed image data to external monitors, televisions, and other display devices for image display. Different graphics cards support different display technologies, such as 2D or 3D graphics, resolution, pixel rate, and refresh rate. To achieve optimal display quality, both the monitor and the graphics card must support the same display technology standards. Graphics cards have an independent graphics processing unit (GPU) that independently handles complex image-related operations, offloading the CPU load and improving overall system performance.

[0031] As introduced in the background technology, 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.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] In this embodiment, a display system is provided. As used below, the term "module" may refer to a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation using hardware, or a combination of software and hardware, is also possible and contemplated.

[0034] The following introduces the display system provided by the embodiments of the present disclosure.

[0035] FIG1 is a schematic diagram of a display system according to an embodiment of the present disclosure. As shown in FIG1 , the device includes:

[0036] A control unit 10, configured to send control instructions;

[0037] Specifically, the control instructions sent by the control unit may include screen update control instructions, brightness control instructions, color setting instructions, display area setting instructions, display mode setting instructions, and parameter query instructions. The screen update control instructions are used to control the refresh rate and refresh mode of the display. These instructions can set parameters such as the refresh interval, refresh direction (vertical or horizontal), and scan area range, implementing customized display update strategies to improve display performance and reduce display power consumption. Brightness control instructions are used to control the brightness level and contrast of the display. Different brightness settings correspond to different light source powers. This instruction can flexibly adjust the brightness of the display based on ambient light changes or user experience to achieve optimal visual display effects. Color setting instructions are used to set the hue and saturation of each color channel (the three primary colors of red, green, and blue) of the display. This instruction allows for flexible adjustment of the display's color output capabilities, achieving rich and diverse color display effects and improving the user experience. Display area setting instructions are used to set the size and position of the actual content displayed on the display. This instruction can control the equivalent box range of the displayed content by limiting the upper left and lower right points of the display area, achieving a customized display ratio and layout of the displayed content. The display mode setting command is used to set the monitor's display mode, such as monochrome, color, or high-color. Different display modes correspond to different pixel format color spaces, and this command allows for flexible switching of the monitor's display mode to meet diverse user needs. The parameter query command is used to query the monitor's key display parameters, such as the number of colors, color depth, and pixel density. By proactively querying these key parameters, the system can verify whether the monitor's current capabilities meet or exceed design requirements and make timely adjustments. This is crucial for optimizing display quality while balancing performance.

[0038] The display unit 20 directly connected to the control unit 10 includes a storage module 21, which is used to store target display information. The display unit 20 is used to receive the control instructions sent by the control unit 10, and obtain and display the target display information of the storage module 21 according to the control instructions.

[0039] Specifically, the display unit can be a liquid crystal display, an organic electroluminescent display, an electric disk display, or a touch screen display. Among them, a liquid crystal display (LCD) is the most common and commonly used type of display. It displays images by controlling the arrangement of liquid crystal molecules and is thin, light, and has low energy consumption. Mainstream LCD resolutions include WVGA, QVGA, VGA, WVGA, FWVGA, etc. An organic light-emitting diode display (OLED) displays images by emitting light through an organic charge transport layer and has advantages such as high contrast, fast response time, and a wide viewing angle. OLED displays are primarily used in high-end mobile phones and tablets. An electronic ink display displays images by controlling the movement of charges in an oil separation layer and has advantages such as high contrast and low energy consumption, but has a lower refresh rate and is currently primarily used in e-books. Compared to ordinary displays, touch screens support touch input of displayed content and generally employ the above display technologies in conjunction with a touch panel. Specific touch panel technologies include resistive, capacitive, and infrared. Touch screens are widely used in display designs and are used in mobile phones, tablet computers, mobile phones, etc. The above-mentioned storage module may be a Flash memory.

[0040] This embodiment provides a display system comprising a control unit and a display unit, wherein the control unit is configured to send control instructions; the display unit, directly connected to the control unit, includes a storage module configured to store target display information; the display unit is configured to receive the control instructions sent by the control unit and, based on the control instructions, retrieve and display the target display information from the storage module. By enabling direct communication between the control unit and the display unit, the display unit directly accesses and displays the information stored in the storage module. This display system does not rely on graphics card data output, thereby resolving the issue of image delay affecting user experience.

[0041] In a specific implementation, as shown in FIG2 , the display system further includes a touch unit 30 in communication with the control unit 10, configured to receive touch signals and convert the touch signals into touch information, which is then sent to the control unit 10. The touch information includes at least touch position information. This system is further applicable to the field of touch display.

[0042] Specifically, the display unit is responsible for actually displaying images and content. It typically uses technologies such as liquid crystal displays (LCDs) and organic luminescent displays (OLEDs), displaying images by controlling pixels, light, or liquid crystals. The display refreshes and updates the display based on commands from the motherboard controller. The touch panel unit, mounted on the front or back of the display, detects user touch input and converts it into electrical signals. Currently, mainstream touch panel technologies include resistive, capacitive, and infrared. These detect touch by varying resistance or capacitance, or absorbing infrared light, respectively, and transmit 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 touches or releases a touch point on the touchscreen, the motherboard controller identifies the corresponding touch point and its coordinates, driving the display to update the content in response to the user's action. Furthermore, the motherboard also performs reset, calibration, and parameter optimization of the touch system to ensure proper operation.

[0043] The control unit of the present disclosure is used to receive the touch information and generate the control instruction based on the touch information. The system can further generate the control instruction quickly.

[0044] Specifically, after receiving the coordinate information of the touch point, the motherboard controller determines the display content or control corresponding to the touch point. If a corresponding control is found, its identification information will also be transmitted. Based on the identified control information, the motherboard controller generates corresponding control instructions for operation. For example: for a text box or list box, it may be instructions such as setting the cursor position and selecting text. For a button, it may be an instruction to simulate pressing or releasing the button. For a form control, it may be instructions such as entering characters and selecting options. For a screen object, it may be an instruction to modify the object's properties such as position, size, and color. The motherboard controller transmits the generated control instructions to other components for execution, completing the device operations required for human-computer interaction. Repeating the above steps, the system continues to generate and execute relevant control instructions based on the user's subsequent touch operations, responding to user interactions in real time, and building a richer user experience.

[0045] The display unit is further configured to display the target display information in a target area of ​​the display unit according to the control instruction, wherein the target area is the projection area of ​​the touch area corresponding to the touch position information on the display unit. The system can accurately locate the touch area and further display it.

[0046] Specifically, the touch unit detects the user's touch location and converts it into an electrical signal. This signal is then converted into the coordinates of the touch point and transmitted via an interface to the mainboard controller. Typically, the touch panel is located above the display panel: this approach is simple and practical, suitable for standard touchscreen displays. The touch panel is located on the surface of the display screen. By touching a location on the panel, the user directly perceives the content and current display state of the display, achieving a direct visual and tactile correspondence, resulting in a more intuitive and natural user experience.

[0047] In some embodiments, the display unit is further configured to update historical display information of a target area of ​​the display unit, and display the target display information in the target area of ​​the display unit. The system can further implement updating of historical display information.

[0048] Specifically, historical display information can be updated through the following methods: For example, modifying pixel values ​​to update text content and image display; updating the display by setting the RGB value of each pixel; modifying video memory data to refresh a specified display area; pushing data to the video memory to achieve regional refresh display on the display controller; modifying display attributes such as display hierarchy and transparency to control the overlay relationship of display objects; and updating the display effect by setting relevant parameters on the display controller.

[0049] In some embodiments, displaying the target display information in the target area of ​​the display unit according to the control instruction further includes: updating the serial number of the target display information in the storage module.

[0050] Specifically, the MCU receives a positioning signal from the touch IC and notifies the TCON that it needs to update the position and update the library number and its corresponding color information. The TCON directly calls the local update block (customizable and different from the built-in content) from the flash memory to replace the current update position and display it. In addition, it can also update the library index number.

[0051] As an optional solution, the display unit includes: a logic board for obtaining the target display information from the storage module, receiving the control instructions and converting them into drive signals; and a display module communicatively connected to the logic board, receiving the drive signals and displaying the target display information from the storage module based on the drive signals. The system further refines the internal structure of the display unit.

[0052] Specifically, the above-mentioned logic board is the screen driver board, which is used to receive and parse image data containing pixel color information (RGB values). The data is then processed to solve problems such as pixel mapping and baseboard normalization. Then, the image is divided into multiple rows and columns of pixel areas, corresponding to the row and column structure of the actual display panel. And the pixels are mapped accordingly. According to the row and column information and pixel mapping, the RGB value of each pixel is generated and output as pixel display data. According to the relevant control signal, the RGB pixel data is updated at the appropriate time, and the display panel is controlled to refresh the displayed image content. The display panel updates the display screen according to the changes in the received RGB data. By continuously refreshing the RGB data and controlling the display panel, it is ensured that the display always displays the latest image content, thereby achieving real-time update display of the image.

[0053] In an optional solution, the control unit is further configured to set a communication protocol between the logic board and the control unit so as to enable direct communication between the control unit and the display unit. This system can further quickly achieve direct communication between the control unit and the display unit.

[0054] Specifically, setting up the communication protocol between the logic board and the control unit primarily involves setting the communication method, describing the communication protocol, configuring communication commands, setting response signals, and handling errors. The main communication methods include serial communication (SPI, I2C) and parallel communication (dividing channels based on timing). Serial communication is simple and easy to use, but has lower data transmission efficiency, while parallel communication is the opposite. The communication protocol description specifies the protocol version, communication rate, maximum packet size, and end signal for both communicating parties. This ensures that both parties quickly understand and use standard communication methods. All commands for operating the screen driver board should be included in the protocol, along with parameters and instructions. This includes commands for pixel data transfer, display area refresh, and parameter settings. After a command is correctly executed, the screen driver board should generate a corresponding response signal for confirmation. This prevents system malfunctions caused by erroneous command transmission and communication interruptions. All possible errors during the communication process should be considered and handled accordingly to ensure system stability. Furthermore, the error type, error code, and handling method should be specified in the protocol.

[0055] In another optional solution, the target display information includes at least one of the following: virtual keyboard information; cursor information; and temperature information of the control unit. This system can further enhance user experience.

[0056] Specifically, in actual applications, when a user uses a touch-screen electronic device, a virtual keyboard adapted to the screen size often appears, i.e., the aforementioned virtual keyboard information. Furthermore, in some cases, the user can use the aforementioned cursor information to clearly identify their touch location. The aforementioned temperature information from the display control unit can further help the user understand the usage of the electronic device.
