Energy saving

    Of course, the masses can most directly experience the advantages of edge-lit LED backlights, that is, the overall energy consumption of the TV is reduced. Generally, 32" LED backlight TVs usually consume 80W at the current level Lcd Module. This level is equivalent to the third level in the country’s latest power efficiency specifications Liquid Crystal Display.

     If manufacturers want to improve TV energy consumption specifications, there are many corresponding solutions, but the use of high-performance brightness enhancement film should be the simplest and direct and effective way to improve energy consumption. If we cooperate with high-performance brightening film, the energy consumption can be reduced by about 20%-30% under the same brightness level (after all, it depends on the skills of each brand). From a numerical calculation, the energy consumption of the TV can basically be improved from 80W to 60W through the high-efficiency brightening film. The improvement of energy consumption not only allows manufacturers to vigorously cooperate with the national environmental protection policy, but also slightly assists consumers in related electricity bills LCD Display Module.

    From the above technical analysis, we can see that the edge-lit backlight design has great advantages for manufacturers and consumers. In the near future, edge-lit single-sided single LEDs must be the ultimate destination of LED backlights.

    The side-light type is also called the side-in type, and one of its biggest drawbacks is that it cannot be partially dimmed. Because the LED lights are gathered on the edge of the TV, the light must be uniformly output to the TV screen by the light guide plate. Therefore, it is difficult to adjust the brightness of a certain area of the screen. The direct type, because a certain part of the LED switch can be completed through the LED driver chip, so the partial dimming advantage is significant. As a result, a new partially dimmable matrix backlight plan that links the advantages of direct and side-by-side technologies has emerged, and has become a key research direction for backlight manufacturers Active Matrix LCD.

As a result, a new partially dimmable matrix backlight plan that combines the advantages of direct-down and side-in technologies has emerged.
