Agilent launches breakthrough flat panel TV lighting system

Agilent Technologies Inc. (Agilent Technologies) before the date announced for the backlight LCD (liquid crystal display) flat-panel TV provides the color management system breakthrough, its bright color enhanced by 25% than the fluorescent backlight current. The color management controller IC (integrated circuit) and the color sensor module are combined to form a complete tone (color) and intensity (brightness) control system.

Agilent lighting and color management system can be used for the production of Lumileds Lighting high power Luxeon red, green and blue LED (light emitting diode). Lumileds is a joint venture between Agilent Technologies and PHILPS electronics.

Agilent innovative solutions by providing closed-loop optical feedback system to solve the problem of LCD TV display manufacturers in the past RGB LED has been a headache. The system enables the OEM to achieve plug and play function, and can be maintained throughout the service life of the TV display.

Initially, this technology is mainly used in the control of LCD flat-panel TVs RGB LED backlight. This color management function can also be used to dynamically adjust the household and business atmosphere lighting, indoor lighting, Infotainment and car dashboard color and brightness, and the logo and other types of display color matching.

At present, the majority of flat-panel LCD TV display backlight using cold cathode fluorescent lamp (CCFL). Although the economy is more, but the brightness of the CCFL will gradually decline, the color will change over time, its service life is generally 15000 - 25000 hours. In addition, CCFL light source can cover only 75% of the National Television System Committee (NTSC) color space, NTSC is responsible for the development of U.S. television and video standards. Agilent lighting and color management solutions RGB LED over 100% NTSC color space to provide a clearer, brighter colors. The use of LED is also helpful to European manufacturers seeking to eliminate the small amount of mercury used in fluorescent backlighting.

Agilent lighting and color management solutions enable a white backlight (combined with red, green and blue and feedback controls) to maintain a stable color and brightness throughout the life of the monitor. This level of control is associated with an increase in the color spectrum that cannot be achieved by any conventional technique.
