The display mainboard comprises a wireless transceiver module, a processor module, a signal input module, a liquid crystal driving module, a key, an SD card and an audio output module. The audio output module and the earphone shown in fig. 1 are for monitoring the audio signal embedded in the video signal, and may be omitted in the embodiment. The SD card is mainly used for importing a user 3D LUT file, facilitating color correction of the wireless monitor 100. The key 4 is used for controlling a display function menu, such as selecting whether a wireless transceiver module transmits or receives, communication pairing of wireless video signals, configuration of transmitting power and the like; the keys and the SD card on the display main board are not limited to be arranged on the main board, and the keys and the SD card may be separately arranged as the key board and the SD card board according to the size of the main board of the wireless monitor 100.

When the wireless transceiver module of the wireless monitor 100 operates in the transmitting mode, the system operation block diagram is shown in fig. 2. The signal input module encodes the signal to adapt to the signal input format of the processor module and then accesses the processor module. The processor module divides the input signal into two, and one path of the input signal is sent to the liquid crystal driving module so as to drive the display screen to display the input signal. And the other path is sent to a wireless transceiving module, and the input signal is encoded and then transmitted out through an antenna in a transmitting mode. The receiving end equipment receives the signal and outputs the signal after decoding by the wireless receiving module.

When the wireless transceiver module of the wireless monitor 100 is in the receiving mode, the system operation block diagram is shown in fig. 3. The transmitting device transmits signals of a camera or other signal sources through the antenna, the antenna of the wireless monitor 100 receives the signals and then accesses the wireless transceiver module, and the input signals are decoded and then sent to the processor module in the receiving mode. The wireless monitor 100 may also access a path of other signals that may need to be monitored from the signal input port, and the signal is accessed to the signal input module, which encodes the signal to adapt to the signal input format of the processor module and then accesses the processor module. The processor module selects one path between the signal input module signal and the wireless receiving signal according to the current working mode and sends the selected signal to the liquid crystal driving module, and the display screen is driven to display the currently selected signal. In particular, the processor in the processor module may be implemented by an FPGA or an ASIC.

As shown IN fig. 11, the HDMI IN signal input port is connected to an HDMI signal and input to the signal input module, the chip used by the signal input module is V59, and V59 is a highly integrated chip for television system solutions from Mstar corporation, and supports the HDMI decoding function and high-speed RISC CPU. The V59 converts the HDMI signal into an LVDS signal and sends the LVDS signal to the processor module, and in specific implementation, the processor in the processor module may adopt an FPGA5CGXBC4C6F23C7N of Altera, and the V59 outputs audio data of the HDMI signal in the form of analog audio, and the audio is converted into digital audio by an audio ADC chip CS4345 after being output and is input to the processor module. The processor module converts the received video signals into TTL video signals to be output, and the signals output by the signal processor are converted into MIPI signals of a display screen through the MIPI signal bridging chip SSD2828, and the MIPI signals are used for driving a liquid crystal display screen of the MIPI interface. The processor module directly outputs the input digital audio signals, converts the digital audio signals into analog audio through an audio DAC (digital-to-analog converter) chip CS4344 and outputs the analog audio signals to the 3.5mm earphone port 10 through an audio power amplifier SGM 4809. In addition, wireless video and wireless audio are bidirectionally transmitted between the wireless transceiver module AR9201 and the processor module through the video interface BT1120 and the audio interface I2S. V59 passes through the serial ports and is connected with singlechip STM32, configures wireless transceiver module AR 9201's mode through STM32, and it is in transmission state or receipt state to configure wireless transceiver module AR9201 promptly to V59 can upgrade for singlechip STM32 through the serial ports, and the so-called upgrading is that the user rewrites some configuration information of STM32 according to the demand. Button 5 is connected to V59 and wireless monitor 100 is configured via button 5. If the key 5 configures the working mode of the wireless monitor 100 as a transmission mode, the processor module transmits the received video signal to the wireless transceiving module AR9201 through the BT1120 interface, transmits the audio signal to the wireless transceiving module AR9201 through the I2S interface, and converts the audio/video signal into a wireless signal and transmits the wireless signal through the antenna by the wireless transceiving module AR 9201. If the button 5 configures the wireless monitor 100 to be in the receiving mode, the processor module receives the video signal transmitted by the wireless transceiver module AR9201 through the BT1120 interface and receives the audio signal transmitted by the wireless transceiver module AR9201 through the I2S interface. The SD card reads data through the SD card reading control chip GL823, converts the data of the SD card into a data form which can be identified by a back-end chip, and respectively sends the data to the wireless transceiving modules AR9201 and V59 through the data conversion chip TS3USB221, so that the wireless transceiving modules AR9201 and V59 can be upgraded, and a color correction file can be imported through V59.

A layer of cover glass (not shown) may be added to the outside of the display 3 to protect the display 3. The rear shell 8 is provided with a battery buckle plate 7 which can be used for hanging a camera battery to supply power for the wireless monitor 100. Since the position of the camera is usually changed at the shooting site, the receiving end is correspondingly changed in position for better wireless transmission, and handles 2 can be additionally arranged at both sides of the wireless monitor 100 for better grasping. The top of the wireless monitor 100 is provided with an antenna shield 1, and an external antenna is disposed inside the antenna shield. Of course, the antenna is not limited to an external antenna, and may be an internal antenna, or an antenna component with different gains selected according to the distance of the application scenario.

As shown in fig. 6, a DC interface 6, an SD card interface 12, a signal input interface 11, a 3.5mm headphone interface 10, and a 2.5mm headphone interface 9 are sequentially arranged at the bottom of the wireless monitor 100. The DC interface 6 is used to supply power to the monitor from an external adapter, and the signal input port 11 is illustrated as an HDMI port, and may also be in the form of an SDI port or other signal input interface for a signal source. The 3.5mm earphone port 10 is an audio output interface and is used for monitoring signal audio. The 2.5mm headphone port 9 is a debug interface, and can be used for upgrading the processor module firmware of the wireless monitor 100, and also can be used for color correction, and the interface form can also be USB.
