7-1 Backlight

An LCD panel does not emit light itself. For the display, a light source is required, and normally fluores-
cent lights are used for the backlight of the LCD television.
The backlight consists of fluorescent lights, a reflective plate, and a diffusion sheet (or board). Fig. 30
shows the structure and photograph of 30V and 15V LCD televisions backlights.
