Colour management enables LED TV backlighting

A novel colour management system for backlighting LCD flat-panel TVs is claimed to deliver 25% more brilliant colours than current fluorescent backlighting.

Agilent has developed a breakthrough colour management system for backlighting LCD (liquid crystal display) flat-panel TVs that delivers 25% more brilliant colours than current fluorescent backlighting.

The colour management controller IC (integrated circuit) and colour sensor module combine to produce a complete hue (colour) and intensity (brightness) control system.

The Agilent illumination and colour management system works with high-power Luxeon red, green and blue LEDs (light-emitting diodes) from Lumileds Lighting.

Lumileds is the joint venture between Agilent and Philips Electronics.

"For years, manufacturers have struggled with how to provide a sharper, more natural colour tone for their LCD TV displays", said Soo-Ghee Lee, Vice President and General Manager for the Optoelectronic Products Divis
