With the simplification of design, the efficiency and brightness of the LED light is improved. It is predicated that the high-efficiency LED can be applied in the backlight module of the liquid crystal display in the year of 2012. The permeability of LED backlight liquid crystal display is only eighteen percent in this year, and it will reach sixty percent in the year of 2012. Currently, the up and down edge lighting design is the mainstream of backlight construction.

The brightness of LED will be in the left and right side, and use one stick of the LED in the year of 2012. From the view of liquid crystal display, there are two kinds of different backlight design, one is the edge lighting design, and the other is the direct type. According to the statistics, about ninety-two percent of the backlight LED modules use the edge lighting design, and about eight percent of the backlight LED modules use the direct type. In the year of 2012, the ratio takes by the edge lighting will decrease to eighty-six percent, and the ratio of the direct type will be fourteen percent.

It is understood that the four edge lighting and six sticks LED was used in the liquid crystal television in the past year. The efficiency was 0.4 watt，and the brightness was less than lumen. In order to simplify the backlight design, many large television system and panel manufacturers are trying to develop the new construction. The LED, which is illuminating by single edge and only using one stick, will emerge and be used in the TV in 2012. The high efficiency light will be the mainstream in the future, which has more than one watt power and one hundred lumens brightness. The related integrated circuit is AD9948AKCPZ.
