Samsung motor successfully developed a notebook LCD panel with 2.5cd LED

[Nikkei BP news] South Korea's Samsung motor (Samsung ELectro-Mechanics) successfully developed for the LCD panel light source 2.5cd white LED (Light Emitting Diode). The development of LED mainly as a notebook computer (PC) and car navigation system in small and medium size LCD panel light source.

Compared with the current widely used 1.5 ~ 1.7cd LED, the development of the product brightness increased by 50%, but the power consumption remained at the same level. The original use of about 50 1.7cd LED laptop panel if the use of the LED, the amount can be reduced to half; if you use the same number, the brightness of the LCD screen can be increased by 40%.

If the use of LED instead of CCFL (cold cathode tube), LCD screen becomes brighter and clearer at the same time, the LCD panel power consumption can be reduced by 40%. In addition, compared with the use of CCFL, the thickness and weight of the LCD panel can be reduced by 20%, so it is expected to play an important role in reflecting the market trend of product supply.

Samsung motor in the use of the LED on the development of the company's high brightness LED chip, self-developed fluorescent materials and packaging technology. At present, mobile phones, portable media players and other small and medium size LCD panel light source most of the LED, and notebook LCD panel is less than 5%. In the notebook computer applications have begun, is expected to spread to more than 60% within 3 years. The company plans to continue to improve its competitiveness in the future, such as improving the luminous efficiency of LED chips, the use of large diameter wafers in LED manufacturing processes to improve production efficiency, etc..
