Low-cost integrated liquid crystal display monitor

Abstract

A liquid crystal display device (8) includes a TFT LCD panel (10), a power/inverter board (20) and an interface board (30). The LCD panel includes a liquid crystal display (12), a backlight module (14) and a driving circuit (16). The power/inverter board and the interface board are installed on one printed circuit board (40), and a certain distance is left therebetween. An inverter circuit of the power/inverter board is electrically connected with a CCFL (142) of the backlight module and is used to convert direct current (DC) into alternating current (AC) to light on the CCFL. The interface board is electrically connected with the driving circuit and is used to receive RGB (red, green and blue) signals, process and send said signals to the driving circuit. That the power/inverter board and the interface board are integrated on one printed circuit board reduces the cost of the liquid crystal display device and ensures stable work thereof.
