[0024] In the specific implementation process of the present utility model, the main board adopts the GD32F103C8T6 microcontroller.
[0025] Specifically, the mainboard uses the GD32F103C8T6 microcontroller, which is a high-performance and low-power microcontroller with an operating frequency of up to 72MHz. It can support advanced communication interfaces and is equipped with a 32-bit embedded core with excellent computing power. It can improve the processing performance of the conference all-in-one machine without increasing consumption. The specific circuit architecture is shown in the figure below. Figure 2 As shown, pin 42 of the GD32F103C8T6 microcontroller is connected to the clock line, and pin 43 is connected to the data line.

[0026] In a specific implementation of the present invention, the power management module includes a first power board and a second power board, and the first power board is connected to the second power board via an enable signal pin.
[0027] The second power board adopts a TOSN-LD1810P open power board.
[0028] Specifically, the power management module includes a first power board and a second power board. The first power board is the main power supply. The first power board supplies 18V to the open pluggable standard adapter board and 5V to the standby mode of the conference all-in-one machine. The first power board is connected to the second power board through the enable signal pin and is connected to the rocker switch, so that one power switch can control multiple power boards at the same time. Reliable power output can be achieved through the connection of the enable signal pin. The second power board adopts the TOSN-LD1810P open power board. The TOSN-LD1810P open power board supplies power to the LCD display. It can power the backlight control of the display module through the DC input of the first power board.

[0029] In the specific implementation process of the present invention, the display module includes a backlight module and a liquid crystal display screen, and the backlight module includes a plurality of low blue light LED lamps.
[0030] Specifically, the backlight module in the display module is designed to provide sufficient brightness and evenly distributed light. It incorporates several low-blue light LEDs to achieve uniform radiation distribution. Requirements for the low-blue light LEDs are: the module / lamp bead spectrum [absolute energy in the 415-445 wavelength band] / [absolute energy in the 400-500 wavelength band] <35%, and the module / lamp bead color temperature requirement is 9000-11000K. Furthermore, the low-blue light LEDs can utilize 405nm violet LED phosphors and 430nm orange phosphors to achieve comprehensive spectrum optimization and thoroughly reduce blue light intensity. The LCD screen uses a blue light-blocking film in front of the screen, or a specialized low-blue light absorbing coating is precisely applied to key layers of the LCD screen. This coating effectively blocks high-energy, short-wavelength blue light. The combination of the low-blue light LEDs in the backlight module and the LCD screen effectively blocks blue light, reducing the risk of eye fatigue and vision loss with minimal impact on the display quality.

[0032] The second HDMI receiver uses an MS9288A converter, and the fourth HDMI receiver uses an IT66353 retimer switch.
[0033] Specifically, the second terminal board is a front terminal board for controlling HDMI signals. The second terminal board includes a first HDMI receiver, a second HDMI receiver, a third HDMI receiver, a fourth HDMI receiver and a fifth HDMI receiver, which are connected to the main board through the front terminal board input terminal to form a complete control circuit to realize signal transmission and control. The first HDMI receiver is used for front HDMI signal access detection and touch switching of front HDMI and TYPE C signals. The second HDMI receiver is used to convert Video Graphics Array (VGA) signals into HDMI signals. The second HDMI receiver adopts MS9288A converter. MS9288A converter is a low-cost, low-power and high-performance VGA to HDMI converter with a maximum conversion rate of 165MHz. At the same time, MS9288A converter also has a maximum sampling conversion rate of 165MSPS. It has automatic phase gain offset adjustment function, transition color enhancement function, dynamic peak enhancement function and black and white enhancement function, which can realize high-precision conversion of HDMI signals and ensure the picture display effect of the conference all-in-one machine. Figure 3 As shown, pin 9 of the MS9288A converter is connected to the HDMI hot plug detection circuit to improve the reliability of HDMI signal conversion. It also includes a pin connector for the serial communication bus to ensure reliable connection of the device. The third HDMI receiver is used to detect the presence or absence of the HDMI signal to ensure the complete transmission of the HDMI signal. The fourth HDMI receiver is used to implement HDMI input port switching. The fourth HDMI receiver uses the IT66353 retimer switch. The IT66353 retimer switch is an HDMI input interface switcher that supports a maximum signaling rate of up to 6Gbps / channel, complies with the latest HDMI2.0b specification, and is backward compatible with the HDMI1.4 specification. At the same time, since the IT66353 retimer switch has a 6Gbps / channel capability, it can support ultra-high-resolution content streams to obtain excellent eye diagram quality, such as Figure 4As shown, pins 11-14 of the IT66353 retimer switch are connected to the first eight-pin resistor, and pins 6-9 are connected to the second eight-pin resistor. By connecting the eight-pin resistor, voltage fluctuations on the line can be buffered, while the signal-to-noise ratio can be reduced, mutual interference of signals can be reduced, and the accuracy of HDMI signal transmission and control can be improved. The fifth HDMI receiver is used for open pluggable specification detection and touch, and is also used to identify the HDMI pin header to determine whether the device is installed. The five HDMI receivers built into the second terminal board can improve the efficiency and accuracy of signal conversion, while enhancing the resolution and clarity of the picture display, providing high-quality picture display effects.

This long-wave blue light chip can effectively block harmful blue light, which has a wavelength of 415nm-455nm. The all-in-one conference machines currently used in the market usually use a blue light chip of 457.5-462.5nm, and its effect of blocking harmful blue light cannot be compared with that of the long-wave blue light chip. By coordinating the long-wave blue light chip with the display module, the harmful blue light ratio can be reduced to less than 50%.

[0037] Specifically, the AD82584F digital audio amplifier can provide advanced audio processing functions such as volume control, equalization effect band, audio mixing, 3D surround sound and dynamic range control. Compared with other audio amplifiers, the AD82584F digital audio amplifier is more tolerant to noise changes. At the same time, the AD82584F digital audio amplifier has a powerful built-in anti-burst circuit, which will not produce bursts during instantaneous power on / off or mute / off switching, and can improve the quality of audio output.
[0038] In the specific implementation process of the present invention, the low blue light all-in-one conference machine also includes a tuner, and the tuner is connected to the mainboard.
[0039] Specifically, the tuner is used to adjust the frequency of the conference all-in-one machine to match the frequency of the signal, ensuring stable and clear signal transmission. At the same time, the tuner can also improve the strength and quality of the received signal by selecting the appropriate antenna and enhancing the signal power, ensuring clear and stable signal transmission.
[0040] In summary, the embodiment of the present invention provides a low-blue light all-in-one conference machine. Through the cooperation of the display module and the blue light chip, the low blue light characteristics of the all-in-one conference machine are achieved.
