LED backlight display means to use LED (light emitting diode) as backlight of LCD. The difference from the front light is that the backlight is illuminated from the side or the back. They are used to increase illumination in low light environments and brightness on LCD screens, producing light in a similar way to CRT displays. LED has the characteristics of low power consumption, low calorific value, high brightness and long life.

They are used to increase illumination in low light environments and brightness on LCD screens, producing light in a similar way to CRT displays. LED has the characteristics of low power consumption, low calorific value, high brightness and long life.Extended information:LED backlight structure is mainly divided into two types, single series power supply or multiple series / parallel power supply. Although a single series power supply uses a lower constant current, the input power supply must be raised to the total forward voltage level of the series power supply to drive the LED. On the contrary, although multiple series / parallel LED power supplies need higher constant current to drive, they reduce the demand for high voltage.The demand for boost converters varies depending on cost, complexity and energy conversion efficiency (equivalent to battery life between charging cycles for users). Finally, the best solution will be determined according to the product characteristics, size and performance requirements of the device itself.. LED backlight refers to the display that uses LED as the light source. The liquid crystal itself can't emit light, so it needs additional light source. Generally, we use cold cathode tube as the light source. Compared with LED, the cold cathode tube has a lot of heat and a corresponding increase in volume. Therefore, the display of LED backlight saves power and is lighter.
