Figure 4-9 Principle Diagram of Display
Monitor mainly consists of the inverter board, LCD and the parameter board.
Function describes as following:

The inverter board produces high voltage to illuminate backlight of LCD which is adjusted
by signal control switch and brightness of the IO board output.

Color temperature and Gamma correction data memory in parameter board used matches
LCD so that the corresponding display effect shall be consistent.

Multifunction FPGA generates switch control signal which drives triode to control inverter to
open or shut off high-voltage output.

Multifunctional FPGA generates PWM signal, which drives triode to control output
high-voltage of the inverter to adjust the brightness of the display.

Multifunctional FPGA outputs LVDS digital signal of display, which is sent to screen directly.

Multifunctional FPGA communicates with parameter via 12C signal and supports to adjust
parameters of display.
