LG Display Unveils Sunlight Illuminated LCD for Outdoor Use

LG Display Co Ltd has develope

Leveraging the company'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 said to be 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 is claimed to fall to one fourth the level of indoor energy consumption, providing a significant increase in battery life. The backlight units in conventional notebooks account for more than 75% of the total energy consumption used in LCD panels for notebooks.

In addition, the LCD panel 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.
