First, cold cathode strip lights (Cathode Lighting Systems) were used to illuminate the organically curved faux skylight and the curvilinear ceiling coves above the uppermost wine racks.
While dimming a cold cathode backlight could provide enhanced contrast when viewing dark scenes, this was generally restricted to the whole screen.
Before LEDs, CCFLs (Cold Cathode Fluorescent Lamps) were used and are actually still primarily used.
Gemini Cold Cathode comes with fully integrated digital electronics, providing flexibility for system integration.
This limitation has been successfully removed in SHMs by introducing a cold cathode instead of a thermionic one [37, 38].
LEDinside noted that global sales of LCD TVs with conventional CCFLs (cold cathode fluorescent lamps) as the backlight source will slow down in the coming years because development of such products has hit its ceiling , leaving little room for suppliers to cut prices to trigger consumer demand.
