The Light Sources of Backlights

[vc_row][vc_column css=”.vc_custom_1560701587242{padding-bottom: 50px !important;}”][vc_column_text]It is very important to choose the suitable light source for the design of backlight. The light sources you are using not only determines opto-electronic parameters of consumption, luminance, color and other optical parameters, but also decides the features of using conditions and serving time.

Light sourceĀ  shape Light source kind Light source wave length (temperature) Power Serving time Feature
Consumption (h)

Point source light lamp bulb
2800k 1.0 above 2000 Simple, big, serious heating
Any kind LED 430-700nm 0.038 100,000 Long serving time, low heat, low brightness
Linear source light CCFL Blue red green and the mix color 1.0-10.0 25 High brightness, long serving time, high inverter driving voltage
HCFL 1.0-220 5000-7000 Serious heating
VFD 200mW/cm2 below 5000 High brightness, good uniformity, double power source driving
EL 20mW/cm2 below 5,000 Thin, good uniformity, low brightness, short serving time
OELD 1,000 Thin, good uniformity, high brightness, short serving time
FED 10,000 High brightness, exploring
