1. LED display thin, high power

According to the current market observation, 20CM thick category box so far the world still has a large number of LED display. LED display application field is more and more wide, the existence of safety risks is more and more big, LED display thin, high power has become most of the famous manufacturers production pursuit.

LED displays are competing not only for thickness, but also for more economical and energy-efficient power consumption and better picture quality. Many aspects of technical performance advantage is the core reason for the rapid growth of LED display thin, high power market. Recently, similar products launched by Tongpu are about 1cm thick, which is incomparable to the traditional LED display.

2. LED display large screen stitching

Splicing wall is an integrated system. At present, there are four types of splicing wall. Projection and LED are commonly used. Among them, projection is currently commonly used 3LCD, DPL and LCOS. The price of splicing wall using projection technology is relatively low, and the quality and stability of the picture are relatively high, so the highest cost performance is the mainstream product in the field of splicing wall at present. Although the price of LED splicing wall is relatively high, it is widely used for outdoor digital display because of its resistance to sun and wind and rain.

3.side light dynamic backlight and low power technology

Now the common mass production of large TV products, are the use of direct-down CCFL as a light source, this drive requires Invertor (invert converter) technology, because of the power problem, the use of CCFL as a light source power consumption is relatively large, with the continuous improvement of technology, the power consumption of this technology has been close to the limit. With the introduction of high-end direct-down LED backlight, the technology of reducing power consumption has reached a higher level. With the emergence of high-power LED and the improvement of efficiency, the power consumption of direct-down type is constantly decreasing. There is another breakthrough technology of direct-down LED backlight, localdimming (area control), also known as dynamic backlight technology, which greatly reduces the power consumption of backlight and improves the contrast of TV products. However, it requires a large number of LED, large thickness of TV products, poor aesthetics and flexibility. The large-size side LED backlight technology introduced in the later stage combines the advantages of ultra-thin, beautiful and low power consumption. It is expected that the localdimming technology can greatly reduce the power consumption of the backlight in the large size side light LED backlight. Direct-down LED dynamic backlight is combined with image processing. In dark places, LED reduces current or voltage, which requires relatively high technical requirements for driving circuit, but greatly reduces the power consumption of backlight. The side-entry LED backlight achieves regional control through LED cross control, which reduces power consumption to a certain extent. The side-entry LED large-size backlight combines various advantages. If a breakthrough is made in localdimming, it will be another improvement of the technology.
