[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] Example 1: like Figures 1 to 3 As shown, the present application provides a television display control system 10 , including a TV main board 11 and a half TCON board 12 .

[0025] The TV main board 11 is used to directly output a control signal and control the TV display based on the control signal.

[0026] Through the SOC main chip 111, the chip receives control signals (such as HDMI / AV signals) from external devices (such as disc players, TV boxes, etc.) and converts them into MINI LVDS / CEDS signals, which are directly output to control the TV display. Specifically, after receiving the external video signal, the SOC main chip 111 processes the signal and converts it into a MINI LVDS / CEDS format signal that meets the TV display driving requirements. The signal is directly transmitted to the half TCON board 12 through the screen cable without the need for an intermediate signal conversion step.

[0027] For example, when an external device transmits a video signal via an HDMI interface, the SOC main chip 111 first converts the signal into a MINI LVDS / CEDS signal and then transmits the signal to the TV monitor for image display. In this way, the signal processing process of the TV monitor is more concise, avoiding the complex signal conversion module in the traditional half TCON board 12.

[0028] The half TCON board 12 is used to provide the voltage required by the television display.

[0029] The half-TCON board 12 is only responsible for providing the various power supply voltages required by the TV display and does not involve signal conversion. Specifically, the half-TCON board 12 includes a PMIC 121 unit, which is used to provide the AVDD, DVDD, VCOM, VGH, VGL and other voltages required by the LCD screen. The SUB PMIC 122 unit further fine-tunes and stabilizes the voltage to ensure that the TV display operates in an efficient and stable working environment.

[0030] For example, the PMIC121 unit in the half TCON board 12 can accurately adjust the required voltage to ensure that each part of the TV display (such as the backlight, display area, etc.) obtains the correct power support, avoiding malfunction of the TV display or abnormal image display due to unstable voltage.

[0031] In this embodiment, the SOC main chip 111 in the TV motherboard 11 receives control signals (such as HDMI / AV signals) from external devices (such as a disc player or TV box). The SOC main chip 111 converts these signals into MINI LVDS / CEDS signals, which are then transmitted directly to the half-TCON board 12 via the display cable. The half-TCON board 12 is solely responsible for providing the voltages required by the LCD screen, including AVDD, DVDD, VCOM, VGH, and VGL. The SUB PMIC 122 unit further processes the voltage signals to ensure stable operation of the TV display. In this way, the combination of the TV motherboard 11 and the half-TCON board 12 can directly drive the LCD screen, eliminating the complex signal conversion required by traditional TCON boards. By directly outputting MINI LVDS / CEDS signals from the SOC main chip 111 and providing power to the LCD screen through the half-TCON board 12, this solution effectively simplifies the design of the TV display control system 10 and reduces circuit complexity. It also eliminates the main chip required for signal conversion in traditional TCON boards, reducing system hardware costs and shortening development cycles. By reducing the number of components and circuits, the power consumption of the entire system is optimized, with higher efficiency and reliability, thereby improving the overall performance of the TV display.

[0032] Example 2: like Figures 1 to 3 As shown, the TV main board 11 includes a SOC main chip 111, which is used to convert the received HDMI / AV signal into a MINI LVDS / CEDS signal and control the TV display based on the MINI LVDS / CEDS signal.

[0033] The SOC main chip 111 receives HDMI / AV signals from external devices (such as disc players, TV boxes, game consoles, etc.), digitizes these signals, and converts them into MINI LVDS / CEDS signals suitable for TV displays. Specifically, the SOC main chip 111 first decodes the received HDMI / AV signals, and then converts the signals into MINI LVDS / CEDS format through its internal video decoding module. This format fully matches the display requirements of the TV display, thereby accurately driving the TV display to display images.

[0034] For example, when an external device sends a high-definition video signal via the HDMI interface, the SOC main chip 111 converts it into a Mini LVDS format and transmits it directly via the screen cable to the half-TCON board 12, ensuring that the TV display can clearly and accurately display the image content. In this way, the signal processing process of the TV display is simplified, avoiding the complex signal conversion and multiple interfaces required in traditional TV display systems.

[0035] The TV mainboard 11 further includes a power supply circuit unit 112 , which is configured to provide voltage and current required by the TV mainboard 11 .

[0036] Through the power supply circuit unit 112, the TV mainboard 11 can provide the required stable voltage and current for various parts such as the SOC main chip 111, the wireless module, and the external terminal unit 114; specifically, the power supply circuit unit 112 converts the input AC power into multiple different DC voltages through rectification and voltage stabilization, including 5V, 12V, 3.3V, etc., to respectively supply the power support required by each sub-module to ensure stable operation of the system.

[0037] For example, the power supply circuit unit 112 provides a stable 3.3V voltage for the SOC main chip 111 and a 5V voltage for the wireless module unit 113, thereby ensuring the efficient operation of each module and ensuring that the TV display can smoothly receive signals and display content. The entire power management process is efficient and reliable.

[0038] The TV mainboard 11 further includes a wireless module unit 113 , which is used to implement a wireless data transmission function and support wireless network connections, including WIFI and Bluetooth communication protocols.

[0039] Through the wireless module unit 113, the TV mainboard 11 can realize the reception and transmission of wireless data and support multiple wireless protocols; specifically, the wireless module unit 113 supports WIFI and Bluetooth communication protocols, and receives and sends data through the wireless network, such as updating system firmware, connecting to Internet services or Bluetooth devices, and even realizing pairing with smart phones, tablets and other devices.

[0040] For example, when a user controls the TV via a smartphone, the wireless module unit 113 pairs the smartphone with the TV via the Bluetooth protocol and controls basic TV functions such as volume adjustment and channel switching. The design of the wireless module unit 113 enables the TV mainboard 11 to be compatible with various wireless communication protocols, enhancing the flexibility and applicability of the system.

[0041] The TV mainboard 11 further includes an external terminal unit 114 , which is used to provide a variety of external interfaces to support access to external signal sources, including HDMI, AV, USB, and RF interfaces.

[0042] Through the external terminal unit 114, the TV mainboard 11 can be connected to a variety of external devices to expand its functions; specifically, the external terminal unit 114 provides standard interfaces such as HDMI, AV, USB, and RF interfaces, supporting users to access different types of signal source devices, such as game consoles, computers, cameras, DVD players, etc., to achieve diversified signal input.

[0043] For example, a user can connect an external game console to the TV motherboard 11 via the HDMI interface. The TV motherboard 11 receives the HDMI signal from the game console and converts it into a MINI LVDS / CEDS signal via the SOC main chip 111. This signal is then transmitted to the TV monitor, enabling the display of high-definition game images. The external terminal unit 114 enables the TV motherboard 11 to adapt to a variety of signal sources, providing greater compatibility and scalability.

[0044] The half TCON board 12 includes a PMIC 121 , and the PMIC 121 unit is used to provide AVDD, DVDD, VCOM, VGH, VGL, Gamma, and Level Shift voltages required by the TV display.

[0045] Through the PMIC121 unit, the half TCON board 12 provides the various voltages required for the TV display. Specifically, the PMIC121 unit provides a variety of voltages including AVDD, DVDD, VCOM, VGH, VGL, and Gamma voltage according to the working requirements of the TV display. These voltages are responsible for providing the necessary power support for each module of the TV display, ensuring that the backlight, display control, and drive parts of the TV display can work normally.

[0046] For example, the PMIC121 unit provides the VCOM voltage to a TV display, which adjusts the alignment of liquid crystal molecules to ensure display clarity. It also provides the Gamma voltage for color calibration, ensuring color accuracy and natural transitions in the image. Precise control of these voltages enables the TV display to display high-quality images.

[0047] like Figures 1 to 3 As shown, the half TCON board 12 further includes a SUB PMIC 122 . The SUB PMIC 122 unit is used to provide additional voltage stability and includes at least two or more operational amplifier channels.

[0048] Through the SUB PMIC122 unit, the half TCON board 12 provides additional voltage stability to ensure that power supply fluctuations during operation of the TV display will not affect the display effect; specifically, the SUB PMIC122 unit further fine-tunes the voltage through multiple op amp channels to ensure voltage stability and low noise to meet the TV display's requirements for precise power supply.

[0049] For example, the SUB PMIC122 unit accurately adjusts the VGH and VGL voltages through two or more op amp channels, ensuring that the TV display does not display blur or flicker due to voltage fluctuations during operation, thereby improving the stability and visual effects of the TV display.

[0050] In this embodiment, the SOC main chip 111 directly converts signals from external devices into MINI LVDS / CEDS signals to drive the TV display. Simultaneously, the power supply circuit unit 112 of the TV mainboard 11 provides the required voltage and current for each module, ensuring stable system operation. The wireless module unit 113 enables wireless connection to external devices, enhancing the system's intelligence and remote control capabilities. The external terminal unit 114 provides a variety of standard interfaces, supporting connection to different devices and expanding the system's functionality. The PMIC 121 and SUB PMIC 122 units in the semi-TCON board 12 provide precise power management, ensuring stable operation of the TV display under various operating conditions. Through the combined application of these measures, the entire TV display control system 10 not only simplifies the circuit structure and reduces power consumption, but also improves system reliability, scalability, and compatibility, resulting in higher performance and lower manufacturing costs. Furthermore, the system's development cycle is significantly shortened, enabling rapid adaptation to the needs of different types of TV displays, thereby enhancing market competitiveness.

[0051] Example 3: like Figure 4 As shown, the present application also provides an electronic device 20, including a memory 21 and a processor 22, wherein the memory 21 stores a computer program that can be run on the processor 22, and when the processor 22 executes the computer program, the television display control system 10 of Example 1 is implemented.

[0052] In this embodiment, by storing a computer program in memory 21 and executing the program through processor 22, electronic device 20 can effectively control a television display, automatically completing functions such as signal processing, signal conversion, and power management. Specifically, the program in memory 21 enables processor 22 to initiate the entire television display control system 10 process upon receiving an external signal, convert the input signal into a MINI LVDS / CEDS signal suitable for the television display through the SOC main chip 111, and simultaneously control the half-TCON board 12 to provide the required voltage support, ensuring that the television display can stably and accurately display content. In addition, through the execution of the computer program, processor 22 manages and controls additional functional modules such as the wireless module and external terminals, enhancing the intelligent features of electronic device 20 and improving its functional scalability and flexibility. Through this design, the hardware design of the entire system is optimized, costs are reduced, the development cycle is shortened, and the stability and maintainability of the system are also improved. Therefore, this embodiment not only achieves efficient television display control but also enhances the overall performance of electronic device 20.
