LG announced it has developed a 14.1" LCD panel that is illuminated by sunlight instead of the backlight unit when used outdoors. This will improve outdoor readability, while reducing power consumption by 75 percent as well. LG will show off this new panel at CES 2009.
Leveraging LG Display’s “Backlight Data Signal Switching Technology”, the use of selective reflection plates in existing backlight panels enables the switch from reflective mode in a high luminance setting (sunlight) to transmissive mode in a low luminance setting (indoors and at night). This is the first LCD panel to allow users to easily switch from backlight use (transmissive mode) to outdoor reflective mode with the touch of a button.
The display’s outdoor energy consumption falls to one fourth the level of indoor energy consumption, providing a significant increase in battery life. While Backlight units in conventional notebooks can account for more than 75 percent of the total energy consumption used in LCD panels for notebooks.
In addition, this new product resolves visibility issues with a contrast ratio exceeding 9:1 when used outdoors in reflective mode. The display’s contrast ratio ranges from just 2:1 to 3:1 for conventional notebook PCs when used outdoors, implying difficulty in viewing the screen.
Mr. In-Byeong Kang, LG Display’s Vice President and Head of LCD Laboratory, noted, “Our environmentally friendly, 14.1 inch LCD for notebook PC overcomes the challenges of extending battery life in use of notebook PCs outdoors where isn’t likely to be power outlets, while providing superior outdoor visibility.”
During CES 2009, LG Display will showcase its new 14.1 inch sunlight Illuminated LCD for notebook PCs, as well as its newest cutting-edge display technologies featuring improved motion picture response time (MPRT), eco-friendly displays and more in a private room at the Bellagio Hotel.
