LCD LCD started against OLED counterattack"

Samsung and LG launched OLED TV with surface design caused the industry is not a small concern, it is such a surface design, has always been a liquid crystal weakness". In recent years, the topic of liquid crystal on behalf of OLED heard, in order to extend the life, LCD also launched a Jedi counterattack. Recently, after the successful production of SONY LCD TV, Changhong also announced that it will be the first in the fourth quarter of the domestic production of the first LCD TV, LCD TV in the face of intent to make a difference. However, the objective point of view, the design of the surface is not the strengths of LCD, LCD TV LCD can break through the barriers to shoulder the burden of OLED?

Technical barriers to the existence of liquid crystal surface

There are a lot of technical challenges in the process of surface liquid crystal panel, but the introduction of ultra-thin glass substrate can also achieve the effect of surface.

After the CRT spherical design, to the LCD era, color TV began to be popular in the United states. Over the past 10 years, LCD TV's design has been mainly based on the plane, and this design is also gradually ingrained in the minds of consumers. 2013, the emergence of curved LCD TV subversion of the traditional TV design, curved LCD screen is indeed a bright spot.

In fact, the LCD screen to achieve surface design is not easy. Zhu Changchang, deputy chief engineer of TCL Industrial Research Institute, told the China Electronics News reporter: "the difficulty of producing curved LCD screen is that glass and backlight are not easy to bend. Because the glass is relatively thin, bending is a certain degree of difficulty. If the LCD screen bending is not large, and the appropriate size of the TV, then the light source can also be bent. However, TCL has not yet made the surface of the LCD screen program. "

All along, LCD TV screens are using graphic design, the main reason is the relatively high technical threshold. In addition to the glass and backlight, LCD screen surface at the edge of the image quality will be distorted due to the mismatch between the pixel and TFT color filter, resulting in perspective. In addition, polarizer attachment and FPCB (flexible printed circuit board) also need to develop new engineering technology. Although there are many technical challenges, but the introduction of ultra-thin glass substrate, liquid crystal panel can also achieve the effect of curved surface.

In recent years, the panel companies have done a lot of research in the field of liquid crystal surface, which has produced surface and Samsung's LCD panel, and launched a close cooperation with SONY and Changhong. Reporters learned that SONY has been listed on the LCD TV screen surface mainly from SONY AUO, new 65 inch TV 4K surfaces by using liquid crystal panel AUO 100% color gamut; and Changhong TV screen surface is provided by AUO and samsung. In addition to LCD panel manufacturers, upstream supporting enterprises are also constantly new technology research and development. In June last year, Corelle has been a sample of bendable glass to mobile phones, tablet computers and TV manufacturers.

AUO general manager Peng Shuanglang said, curved TV more ergonomic design, so AUO will follow up a victory with hot pursuit again on 2014, the launch of a new generation of wide color gamut, the large size of 4K * 2K surface panel.

LCD OLED challenge

Color TV manufacturers are actively launched surface LCD TV, in order to compete with OLED TV, in order to extend the life of the liquid crystal.

Relative to the liquid crystal, OLED has inherent advantages in terms of flexibility. Since the OLED is a self luminous panel, it does not require additional backlight components as the light source, so the structural design can be better to form a curved shape. In 2013, Samsung and LG launched the OLED TV with a curved surface design.

In Zhu Changchang's view, color TV manufacturers are actively introduced the surface of LCD TV and OLED TV, in order to compete, to prove to the industry, OLED can do the LCD products can do the same, to extend the life of lcd.

In recent years, the replacement of liquid crystal and OLED become the focus. In early 2013, OLED TV is difficult to mass production, LCD seize the opportunity to vigorously develop 4K technology, the size of the OLED posed a severe challenge. In September, Samsung and LG launch OLED TV to surface design as a selling point, the LCD is SONY and Changhong have not resigned to playing second fiddle, introduced the surface of LCD TV OLED TV belong to the original intention to seize the market.

The general manager of Changhong multimedia industry company Xu Ming said in an interview with reporters: "South Korea's Samsung and LG introduced the surface OLED price is too expensive, the LCD TV can also achieve the effect of bending, but there are some details to improve the commercial. "

However, in the eyes of Hong Zhen Dean TCL semiconductor light source Research Institute, OLED - the cost is relatively high, the yield is too low, OLED panel production is relatively small, while the LCD technology has been quite mature, OLED if the plane to the market could not compete with the LCD tv. Therefore, the first OLED TV to surface design to the market, however, the surface design is not conducive to improving the price performance ratio, when the OLED technology is mature, the competition will return to the flat tv.

The development of future market

Curved TV is a flash in the pan or lead the trend of consumption, the industry say different.

Emerging new technologies, much industry expectations. Faced with a number of bottlenecks in the LCD TV LCD, whether it can really take on the challenge of the task of OLED? Reporters learned in the interview, the current industry on the surface of LCD TV views vary, the future prospects for the market to be tested.
