Abstract
A display device containing an LCD light shutter front end to modulate light transmittance and a substantially flat gas discharge back end unit containing multiple gas discharge tunnels. The back end unit contains priming means to allow fast ignition of gas discharge and control means to allow independent discharge control of each discharge tunnel. The control circuit is further simplified to allow a small number of driving signals to control a large number of discharge tunnels. This backlight structure allows color light pulses to be generated in synchronization with the scanning operation of the front end unit. The combined operation of these two units can produce color images through time sequential color mixing principle. Compact and power efficient color display panels can be produced without the use of color filter in the LCD.
