Abstract: Systems for displaying images are provided. A representative system includes a backlight module incorporating a channel, a discharging gas, a fluorescent material, a cathode and an anode. The channel exhibits a series of waves arranged along a length thereof. The discharging gas and the fluorescent material are located within the channel. The cathode and the anode spaced from each other along the length of the channel. The series of waves form an increased effective length of the channel through which electrons travel between the cathode and the anode, and within which the electrons excite the discharging gas to generate ultra-violet light. Responsive to the ultra-violet light, the fluorescent material emits visible light.
