In today's society, the technology people use is constantly changing to meet their needs. The control panels of various smart devices, such as smartphones, computers, televisions, and so on, can all see the presence of these technologies. So, today we will learn about the functions of the LCD display backlight board? Friends who want to know more, let's learn about it together with the editor.
The principle of LCD panel backlighting is to assemble the reflector, light guide plate, upper and lower BEF, LED light strip, and rubber frame iron frame together. When the LED strip is charged, the component emits side view light, which turns into flat light behind the light guide plate and provides backlight for the LCD display screen. The control panels of televisions, mobile phones, computers, and various smart devices all use LCD displays with backlighting.
What is the function of the LCD backlight board? What is the use of it?
1. Mobile LCD panel backlight board
There are several thin films behind the LCD screen of the mobile phone, which are a reflective film (silver), a light guide plate (transparent plastic sheet), and two optical diffraction films (to make the light distribution more uniform).
2. TV LCD panel backlight board
The LCD panel backlight panel of a television is a light source device used to ensure brightness behind the LCD screen. Due to the fact that the LCD panel itself does not emit light, it requires a backlight panel to assist in emitting light. The brightness and uniformity of the backlight panel directly affect the performance of the LCD display.
A backlight panel is actually a high brightness luminous body that is added to the back of a liquid crystal LCD during the manufacturing process. Because the LCD panel of an LCD display does not emit light and can only transmit light, a high brightness luminous body needs to be added to the back.
Although the optical structure of the backlight panel may seem simple, the optical characteristics, size, and relative position of each component form a closely interconnected and interactive relationship with the overall optical performance of the backlight panel.
