The latest OLED display can extend the life time of iPhone

CNET news July 7th International reported a new generation of ultra-thin display power saving is gradually towards the listing of the road, said the battery life is extended to a new realm, some day in the future and may even challenge LCD volume is bulky, power consumption is relatively high (LCD).

New screen can shine, screen image can make the intelligent mobile phone, game machine and portable media player more clearly. By contrast, LCD requires a strong backlight lighting, eat more electricity.

But industry observers said that the new display is to go beyond the LCD, at least until many years later, is still difficult to determine who wins.

Organic light emitting diode (Organic light-emitting diode; OLED) and bistable (bi-stable) technology, a new technology is the most potential challenge LCD.

The power consumption of OLED screen can save up to 40% than the LCD, but also because it does not require backlighting, the thickness ratio is half thin LCD.

These new technology has been applied in some small portable devices, such as a music player, Samsung Electronics and Reigncom factory, and the Japanese Kyocera of a mobile phone.

Small TV consumer electronics giant SONY has plans for the second half of this year sales by OLED technology.

Lehman Brothers in South Korea analyst James Kim said: "the palm of assembly equipment, to display the most power. The most important thing is the power, followed by perhaps brightness. "

Analysts believe that the launch of the apple iPhone mobile phone in the United States last week, the future may adopt more power-saving screen, such as OLED, because the LCD screen type battery life short.

Baode investment securities analyst Kim Woon-ho said: "if you use the apple OLED screen is reasonable. They are trying to improve battery power. OLED manufacturers are also looking forward to the transformation of apple, although the plan has not left a character. "

LCD vendors pay close attention to

New display has caused the Samsung SDI, look at fiercely as a tiger does, SONY LCD manufacturers pay close attention to.

Samsung SDI also manufacture OLED screen, odd crystal photoelectric Taiwan (CMEL) -- pure production OLED, LCD manufacturers CMO's membership is by the universal production.

Market research agency iSuppli expected, low power and low power OLED display LCD display market is expected to 27% annual growth rate of rapid growth, expected annual sales from $6 billion in 2007, the rapid expansion to $24 billion in 2012.

But expensive new technology development, so as LG.Philips LCD LCD manufacturers are expected to continue to improve the existing LCD, such as the use of light sensor technology and new power management for backlight module.

Some experts predict that the OLED technology in the future may be used in large size tv. But OLED manufacturers must first improve the organic material between the poles, and the cost must also come down, then OLED technology can be widely used in mobile phones, PC, as well as ultra-thin TV screen.

Qijing photoelectrical President Chen Zhexiang Peter Chen said: "OLED displays the price of your LCD than 1.7 times to 1.8 times, unless prices down, otherwise not more competitive. "

Another rival OLED is a bi stable display, the display of power can be saved if no image, so it is suitable for public bulletin boards and equipment sub picture (sub-sCREEn). However, the problem of bistable display is the impact of image quality.

Another product is flexible OLED display color. LG.Philips LCD recently released a 4 inch full-color OLED display, but the size is still too small, not suitable for handheld e-book.

New display technology has just started. Some day in the future, the new version of the newspapers and magazines may be wireless updates can also be rolled up or folded up like paper and carry.

Samsung SDI chief technology officer Chung Ho-kyoon said: "when the time comes, we'll know where the real difference in various display. "
