Guide: Sidelight type LEDs are placed on the upper and lower sides of the backlight. The layout adjustment greatly reduces the use of LEDs, thus reducing production costs and energy consumption, which is of great benefit to manufacturers and consumers. However, its weakness of local dimming has led to the birth of a locally dimmable matrix backlighting scheme, a backlighting technique that combines side-in and direct-down.
Recalling the history of TV development, the traditional CRT TV in the home must be the product that everyone thought of for the first time. In 2000, plasma TVs began to appear; around 2003, CCFL (Cold Fluorescent Tube Light Source) LCD TVs began to appear and became popular; until 2010, LED backlight technology gradually replaced CCFL. Most people inside and outside the world should be able to completely replace CCFL as the backlight of the main TV in two to three years.
Most people know that LED backlights have several advantages, including thinner TV thickness, lower power consumption, and richer colors. These advantages are reflected in the public's ability to simply compare with CCFL TV. In addition, the price of LED TV has been declining, making LED TV more advantageous in terms of cost performance. These are the main reasons why LED-backlit TV can be popularized in the market.
During the development of LED backlights, technology has been improving. The development of the original dot matrix to today's sidelight is one of the important technological advancements. Under various obvious advantages, manufacturers have actively developed LED-backlit TVs in recent years. Domestic brands such as Hisense, TCL, Konka, and Skyworth are all working hard to develop their own LED backlights. Among them, technology improvement and cost control are important links. In order to make modern LED backlights popular in the market, everyone has begun to consider the use of LEDs to reduce product costs. But the most important thing is to improve the energy consumption significantly to match the country's latest environmental protection and energy conservation policies. Use less LEDs and adjust them in the backlight array. The original dot matrix type placed the LEDs on the TV backlight on average, while the sidelight type placed the LEDs on the upper and lower sides of the backlight. This layout adjustment greatly reduces the use of LEDs, thereby reducing production costs and energy consumption.
But most people think that LEDs are less used, and the brightness of the screen will not drop? Isn't TV picture quality also falling? This problem is expected by manufacturers early on, so most manufacturers will find the best way to solve it.

The most common solution in the market today is to use high-performance brightening film to improve brightness. The use of brightness enhancement film is different from other solutions. It is simple and straightforward compared to the improvement of glass penetration rate. It does not depend on the development progress of upstream glass suppliers. It is also different from the use of high-performance LEDs, resulting in higher production costs. Problem (generally high-performance LEDs are two to three times more expensive than regular LEDs). The brightness enhancement film is simply an ultra-thin plastic optical sheet. Using it in the edge-lit LED backlight not only does not affect the overall thickness of the TV, but also compensates for the brightness of the TV screen under cost control. Now DBEF produced by 3M Company of the United States can generally increase the brightness of about 30%. If the TV backlight itself has a brightness of only 300 nits, DBEF can be used without any changes, and the illuminance can be increased to about 390 nits.
