LCD liquid crystal backlight boost circuit
The Newman MP4 has two LCD screens, each with a separate LCD display interface circuit. LCD display
The electronic components on the display interface circuit are relatively small, and the detection is also convenient.
The LCD liquid crystal display works normally. In addition to the signals transmitted by the CPU and the decoding chip, an LCD boost circuit is required for the liquid crystal.
The screen provides power, as shown in the figure, the LCD LCD backlight boost circuit. The backlight boost circuit of the MP4 machine is made up of two small pieces
The integrated circuits U4 and U6 are formed.
â—High-efficiency, energy-saving design, full display of green concept from inside to outside
The system adopts a high-efficiency rectifier, the peak efficiency of the rectifier is greater than 96.2%, and the power consumption of the rectifier sleep is as low as 4W or less.
â—The rectifier module is small in size and high in power density, improving the utilization of cabinet space
â—Fully digital design, more stable performance
The rectifier adopts DSP+MCU dual digital circuit control mode, the system adopts CAN+RS485 dual bus control, the system power supply reliability is higher, and the transmission rate is faster.
