LG Display Unveils Sunlight Illuminated LCD for Outdoor Use Company’s 14.1” Sunlight Illuminated LCD Reduces Power Consumption by 75% When Outdoors
Seoul, Korea ( Dec. 22, 2008 ) – LG Display Co., Ltd. [NYSE: LPL, KRX: 034220], a leading innovator of thin-film transistor liquid crystal display (TFT-LCD) technology, announced today that it has developed a 14.1 inch LCD panel for notebook PC that is illuminated by sunlight instead of the backlight unit when used outdoors. The company’s new, sunlight illuminated, energy efficient LCD panel will debut at the upcoming Consumer Electronics Show (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.”
