Who can dominate LED TV backlight technology? - straight white light, side light white light, straight down RGB-LED

Samsung, SHARP, SONY high-profile grab LED TV, the domestic brand TV factory Hisense, Tsinghua Tongfang, SKYWORTH, Haier and other companies also have new products listed. China to the mainland market as an example, Hisense, SHARP, SKYWORTH, etc. are straight with white LED light source technology oriented; and individual top models of SONY and SHARP is using direct type RGB-LED backlight technology; for the LED TV market leader Samsung is the side light type white LED light source. From the point of view of process design, the straight down white LED is the easiest way to replace the traditional LCD backlight applications, the technical difficulty and the need to modify the minimum product design. Therefore, the application of LED light source model has become one of the most popular LED TV application mode; direct type RGB-LED technology, although do not need a major innovation to the original design of the LCD TV, but the complex structure of the backlight module includes a light emitting structure, control structure and the power supply part is more complex, so the an application mode of products less and less difficulty; side light type white LED technology is the main single lamp luminous intensity and the integrated design ability, because of the side structure of the main purpose is to design a more slim TV machine, therefore, the host power supply circuit, LCD TV screen power and heat dissipation both need to slim improvement.

It can be seen that the main difficulty of the design of the straight down RGB-LED is the backlight module itself, although the straight down RGB-LED light source technology is absolutely the first in the comprehensive display, but the price is the highest. The highest cost of this program does not have the possibility of universal market. Therefore, the three kinds of LED light source program competition, in fact, only in the direct light and white light on the side.

The straight white LED and side light type white LED technology compared to the side light type white light due to the need to test the slightly thin, often resulting in many aspects of the cost increase, so the cost is higher than the short-term direct type white LED backlight module more complex. On the other hand, the advantages of the direct down white LED technology in the screen control is obvious, which will lead to the technology of the product in the final image display ability to be superior to the side light white LED technology. However, the real problem is that the advantages of the two will not be significantly stronger than the opponent, and even to the specific product will have the advantage of a disadvantage. It appears that the king of liquid crystal Samsung side LED white light technology, the father of liquid crystal SHARP is keen on the white light LED technology under the bizarre scene. At the same time, the support of straight white LED technology manufacturers more undeniable reason is that the technology of the enterprise's overall system design and integration requirements lower.

Market expectations, the future price of white light LED light source annual decline of at least 20%. In the white LED LCD TV, the cost of light source occupies more than 1/3 of the whole machine. This will inevitably lead to the future of LED TV there will be a huge reduction in the price of space and market acceptance. At that time, maybe the cost is no longer the biggest difficulty to consumers to buy LED TV, consumers need to choose the problem will become a contradiction in direct type large white LED can choose the type of white LED is more thin fashion and function of the local side light source adjustment on the side.

Straight down white LED and side light white LED two who can win the favor of consumers? Perhaps the development process of the notebook display screen can be like consumers to reveal the core trend of foreign LED color tv. At present, the majority of LED notebook computers are using the side of the LED backlight structure, the core advantage is that it is easier to achieve ultra-thin design, while the cost is much lower than the primary LED light source.
