LED backlight refers to the use of LED as the backlight of LCD. Compared with the traditional cold cathode tube backlight, LED has the characteristics of low power consumption, low calorific value, high brightness and long service life. The brightness of LED backlight is high, and the brightness will not drop after long-time use. Moreover, the body of LED backlight is thinner, the appearance is beautiful, and the color is softer. The color of hard screen panel can make the eyes more comfortable. All led backlights have it, which saves electricity and reduces environmental radiation.
