Backlight definition
Backlight is defined as "light cannot be directly illuminated" or "avoiding direct illumination of light". In the electronic industry, backlight is a form of lighting, They are often used in LCD displays.
the difference between backlight and front light is that the backlight is illuminated from the side or from the back.

What does LED backlight mean?

the front light, as its name implies, is illuminated from the front.
they are used to increase the illumination in low light environment and the brightness of computer displays and liquid crystal screens.
they produce light in a similar way to CRT displays.
.
the light source may be incandescent bulbs Electro optic panel (ELP), light emitting diode (LED), cold cathode tube (CCFL) and so on.
the electro-optic panel provides uniform light on the whole surface.
other backlight modules use diffuser to provide uniform light from the non-uniform light source.
.
backlight can be any color.
monochromatic liquid crystal usually has yellow, green, blue, white, white, etc The color display uses white light.
because it covers the most color light.
.
LED backlight is used in small, compact, low-cost and low-cost applications Cheap LCD panels usually have color light.
although white backlight has become more and more common.
electro optic panels are often used in large displays.
at this time, uniform backlight is very important.
electro optic panels need to be driven by high voltage alternating current.
this part is provided by reverse converter circuits.
cold cathode tubes are used in computer displays incandescent backlight is used when high brightness is needed.
however, the disadvantage is that the life of incandescent bulb is very limited,The LED backlight can improve the color performance of LCD display.
the LED light is generated by three different LEDs.
the LED backlight can provide the color spectrum of LCD image point filter.
.
the LED backlight refers to using LED (light emitting diode) as the backlight of LCD display.
compared with the traditional CCFL backlight>With the characteristics of low power consumption, low calorific value, high brightness and long life, LED is expected to completely replace the traditional backlight system in recent years.

in the electronic industry.
backlight is a form of lighting, They are often used in LCD displays.
the difference between backlight and front light is that the backlight irradiates from the side or the back.
the front light, as its name implies, irradiates from the front.
they are used to increase the illumination in low light environment and the brightness of computer monitors and liquid crystal screens.
they produce light in a similar way to CRT displays.

LED backlight is used in small and cheap LCD panels.
its light is usually colored.
although white backlight has become more and more common.
LED backlight is widely used in LCD panelsElectro optic panels are often used in large-scale displays.
at this time, uniform backlight is very important.
electro optic panels need to be driven by high voltage alternating current.
this part is provided by reverse converter circuit.
cold cathode tubes are used in computer displays.
the color is usually white, This also requires reverse converters and diffusers.
incandescent backlights are used when high brightness is required.
however, the disadvantage is that the life of incandescent bulbs is very limited, The LED backlight can improve the color performance of LCD display.
the LED light is generated by three different LEDs.
the LED backlight can provide a color spectrum that is quite consistent with the color filter itself.
