Flat display device blacklight module thereof for night vision imaging system

Abstract

A flat display device is adapted for human eye observation with or without applying a NVIS (Night Vision Imaging System). The flat display device includes a display panel, a backlight module and a backlight driving unit. The backlight module includes multiple red light LEDs (Light Emitting Diodes), green light LEDs and blue light LEDs that form together a light source array, so as to generate a backlight by mixing and projecting the red light, green light and blue light to the display panel. The backlight driving unit is electrically connected with the light source array and used to drive and control the red light LEDs, green light LEDs and blue light LEDs. At a night-vision mode, the backlight driving unit may, upon actuation of a actuating signal, adjust or disable the red light LED by for example decreasing or turning off the driving electricity sent to the red light LED, thereby achieving the requirements for nigh vision purposes.
