[0017] The specific embodiments of the utility model will be described in detail below with reference to the accompanying drawings.

[0018] In one embodiment, as Figure 1As shown, a high-transmittance query machine based on OLED display technology includes an insulating frame and a display system 4. The insulating frame includes an insulating base 1, a metal column 2, and a glass cover 3. The glass cover 3 is a vertical rectangular plate divided into upper and lower parts. The lower glass cover 3 is vertical, while the upper glass cover 3 is processed by a hot bending process to tilt backward by 20°. The metal column 2 has the same curvature as the glass cover 3 and is fixedly embedded in the insulating base 1. The side of the glass cover 3 is embedded in the middle of the metal column 2. The display system 4 includes a power board 5, a display driver board 6, a T-con board 7, a touch control board 8, a touch driver board 9, and an OLED display screen 10. The OLED display screen 10 is located on the upper glass cover. 3. On the surface, the power board 5 is connected to the 220V external AC power supply through a three-phase socket. The power board 5 converts the DC power to provide power to the display system 4 through the motherboard power supply line 11 and the 24V power supply line 12. The power board 5 is connected to the display driver board 6 through the motherboard power supply line 11 and the 24V power supply line 12. The display driver board 6 is connected to the T-con board 7 through the VB1 signal line 13 and the 24V power supply line 12. The T-con board 7 is connected to the OLED display 10 through the FFC cable 14. The touch control board 8 is connected to the touch sensor layer of the OLED display 10 through the touch cable 15. The touch control board 8 is connected to the touch driver through the touch USB connection cable 16. The touch driver is connected to the T-con board 7 through the HDMI signal cable 17.

[0019] In a specific embodiment, the total height of the high-transmittance query machine is 1709.7mm, the width of the glass cover plate 3 is 420mm, the height between the top of the lower glass cover plate 3 and the ground is 1000mm, and the height of the insulating base 1 is 66mm.

[0020] The insulated frame features a user-friendly design, with the glass cover 3 and metal column 2 sharing the same curvature. The upper glass cover 3 is tilted back 20°, providing excellent comfort for users to extend their arms or look down for optimal viewing. Specifically, the power board 5 internally includes voltage conversion circuits, filtering circuits, and overvoltage and overcurrent protection circuits to ensure a stable power supply to the OLED display 10. External power is connected to the power board 5 via a three-phase socket. Turning the switch button on the motherboard to the ON position powers on the device. The voltage conversion circuit inside the power board 5 converts the 220V AC input from the external power supply into a voltage sufficient to drive the pixels of the OLED display 10 and the operating voltage of the control circuits through steps such as step-down (converting high voltage to low voltage) and rectification (converting AC to DC). The filtering circuit removes high-frequency noise and interference from the power supply, improving power control quality. The overvoltage and overcurrent protection circuits monitor the voltage and current of the power supply lines in real time, ensuring a stable power supply from the power board 5 to the device. The power board 5 precisely distributes the converted, stable DC power to various parts of the display device via the motherboard power supply line 11 and the 24V power supply line 12 to meet the voltage requirements of different circuits and components. Current flows into the display driver board 6, which, together with the T-con board 7, is responsible for the transmission and processing of image signals. Due to the self-emissive nature of the OLED display 10, the emission of each pixel requires precise current control. However, the raw signals stored in the device and imported externally cannot be directly used to drive the pixels on the OLED display 10. The display driver board 6, through its integrated signal processing module and driver module, processes the received video signals and image data through its internal signal processing module. After decoding, color space conversion, gamma correction, and other processes, the signals are converted into driving signals that the OLED display 10 can recognize, while ensuring image quality and display effect. Simultaneously, each module can also perform backlight control, touch signal processing, and other functions, further improving the screen's display effect and user experience.

[0021] This solution uses VB1 signal line 13 to replace the traditional LVDS (Low Voltage Differential) transmission method to overcome its limitations in ultra-high-definition screen transmission. Using T-con board 7 (Timing Controller) instead of the driver board's timing control module, VB1 signal line 13 can perform high-speed serial data transmission via CDR (Clock Data Recovery), avoiding electromagnetic interference caused by clock transmission lines. The effective data volume of high-definition digital image signals transmitted via VB1 signal line 13 can reach 3.2Gbps, significantly improving transmission speed while reducing the number of transmission lines, lowering device power consumption, and ensuring long-term operation of the OLED display device.

[0022] The high-definition digital signal generated by the display driver board 6 is transmitted to the T-con board 7 via the VB1 signal line 13. The T-con board 7 processes the data through format conversion and controls the scanning drive circuit, generating and sending control signals to the OLED display 10 for timing control. These control signals include row scan signals, column drive signals, etc. Data processing includes image scaling (converting signals of different resolutions to the optimal display resolution of the OLED screen, ensuring clear and smooth images at any resolution), format conversion (the T-con board 7 can handle multiple input signal formats, enabling the OLED display 10 to be compatible with various video sources and graphics processors), frame rate adjustment (color correction to ensure accurate image colors), and the generation of synchronization signals (the T-con board 7 ensures that the transmission of image data is synchronized with the refresh cycle of the OLED display 10 to avoid image tearing or delays), making the displayed image more vivid and detailed. Through precise data processing and timing control, the T-con board 7 ensures a stable current supply and monitors the screen's operating status, promptly shutting down unnecessary pixels to reduce energy consumption, extend lifespan, and improve display quality.

[0023] The FFC wire is electrically and flexibly connected to both ends of the T-con board 7 and the OLED display 10 along the inner pillar. The FFC wire uses PET insulation material and extremely thin tin-plated flat copper wire. It has the advantages of being flexible, easy to bend and fold, thin, small in size, easy to connect and easy to disassemble.

[0024] The OLED display 10 is equipped with a touch sensor layer to ensure that touch input is accurately mapped to the displayed content. A touch cable 15 electrically connects the touch sensor layer to the touch control board 8, enabling user interaction and touch control functions. When the sensor is not touched, its conductive layer forms a relatively small but stable initial capacitance with the surrounding air or insulating material. When a user controls the screen display via touch, their finger touches the sensor, forming a new touch capacitance between the finger and the conductive layer. This new capacitance is connected in parallel with the initial capacitance, causing the total capacitance value to increase. The sensor detects this change in total capacitance value to determine if a touch has occurred. Multiple such capacitance units are distributed on the sensor array. When a finger touches the screen, it changes the values ​​of multiple capacitance units near the touch location. By detecting these changes in capacitance values, the system can determine the precise location of the touch. The sensor converts the detected capacitance change signal into an electrical signal, and the signal processing circuit amplifies, filters and digitizes the weak electrical signal. These processed signals are transmitted to the touch control panel 8 for further analysis and response to determine the touch position, duration, speed and other characteristics, and to make corresponding responses, such as opening an application or scrolling a page.

[0025] The touch control panel 8 transmits the processed digital signals to the touch driver panel 9 via a USB cable. The USB cable also provides power to the OLED display 10 and the touchscreen module. The touch driver panel 9 receives these signals and decodes and processes them according to preset algorithms and logic to recognize the user's touch actions and intentions. Based on the user's touch actions and intentions, it converts the touch signals into driving signals that the OLED display 10 can recognize and controls the OLED display 10 to perform corresponding operations, such as moving the cursor, selecting menu items, and zooming in or out of images. The results of these operations are displayed in real time on the OLED display 10, providing the user with intuitive visual feedback.

[0026] The touch driver board 9 transmits the drive signal to the T-con board 7 via the HDMI signal cable 17. The data transmission lines on the HDMI signal cable 17 transmit this data in the form of high-speed differential pairs. The differential pairs can cancel out external interference and improve the signal's anti-interference ability and stability. The T-con board 7, through precise data processing and timing control, converts the touch signal into a drive signal that the OLED display 10 can recognize based on the user's touch actions and intentions, and controls the OLED display 10 to perform corresponding operations, such as moving the cursor, selecting menu items, and zooming in or out of images. The results of these operations are displayed in real time on the OLED display 10, providing the user with intuitive visual feedback.

[0027] Based on the above embodiments, in a preferred embodiment, the power board 5, display driver board 6, T-con board 7, touch control board 8, and touch driver board 9 are disposed in the insulating base 1, and the FFC cable 14 and touch cable 15 are disposed in the metal column 2. This arrangement is structurally reasonable.

Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
