LED replaces CCFL is inevitable LCD backlight technology needs analysis

Since entering into the era of the LCD display, the development of technology has never ceased. The first is the size of the dispute, because the user is not satisfied with the small size LCD games and movies in the bad effect, began to chase large size products. With the decline in the price of the panel, in 2007 the major manufacturers of collective product prices. The standard size of the display has been increased from 17 inches to + 28 inches. However, due to the limitations of the TN panel in the visual angle, in 2009, the market has gradually set off a wide range of visual angle boom. Products derived from the high-end wide viewing panel, such as E-IPS and C-PVA products began to enter the market. It can be said that in the display market, almost every year there is a new theme. So what are the technologies that dominate the market now and in the next one or two years? The following Xiaobian to discuss with you.

Energy demands to enhance led replace CCFL is inevitable

At present, consumers in the purchase of the display and compared to previous years has been a great change. In the appeal from the simple requirements of the large size of the function of low energy consumption and long life direction. And we know that backlight technology directly determines the energy consumption of the display. Compared with the traditional CCFL backlight, LED backlight has become the mainstream in the market because of its low power consumption, low calorific value, high brightness, long life and so on.

LCD backlight technology demand analysis

According to the survey conducted by 350 users on the Internet, in the purchase of the display, consider LED products have a total of 182, accounting for 52%. CCFL products will still be considered 91, accounting for 26%, and said that there is no concern about the backlight technology, accounting for 22%, accounting for 77. In more than 1 years ago, a similar survey, said it would buy LED products, the proportion of users is less than 25%. As a result, many manufacturers have even been in the product line to achieve all of the LED. With the further decline in the price of LED products, in the next one to two years, CCFL products are likely to be completely replaced.

3D and touch screen technology will gradually become the new hot spot

3D display market trend analysis

With the increasing popularity of 3D movies, in the home appliance manufacturers have launched 3D LCD tv. Display is gradually showing a trend of 3D. Naked eye 3D display because the design level is more complex, resulting in the higher price (the price is about 2 times higher than ordinary display) so the application in the display area of the mainstream 3D is the main polarization type 3D technology and shutter 3D technology with the eyes of two. Data show that although the 3D display market share is not high, but with the decline in product prices and sources to solve problems, in the next few years, the 3D in the display market share will rise and eventually become the mainstream of the market.

In addition, due to the use of computer products in terms of age showed a more obvious trend of expansion, basically more than 65 years of age and children under the age of 5 have a demand for computers. But traditional keyboards are often not very convenient for them. The touch screen technology as a result of simple, easy to operate, has gradually moved towards the mainstream user base. At present, there are a lot of display manufacturers launched similar products.

Difficult to control the cost of wide-angle LCD is difficult to fully integrate into the mainstream market

Although the wide viewing angle panel in the visual angle and color and other aspects of the advantages of the TN panel can not be compared, but there are a lot of market wide viewing panel LCD display. But in the same size of the premise, even if the current use of such as E-IPS or C-PVA class wide viewing panel LCD, the price is also higher than the use of TN panel LCD 20%. This situation will not have a significant change in a few years, which determines the wide viewing angle display can only be for special needs of users, it is difficult to fully integrate into the mainstream market.
