LG Display unveils LCD monitor panel with smarter touch function

Press release; Yvonne Yu, DIGITIMES [Wednesday 19 May 2010]

Seoul, Korea (May 18, 2010) – LG Display Co., Ltd. [NYSE:LPL, KRX:034220], a leading innovator of thin-film transistor liquid crystal display (TFT-LCD) technology, announced it has developed a full HD 21.5-inch LCD monitor panel featuring optical touch technology.

The panel not only boasts the advantages of capacitive touch technology, which features light and soft touch, but also possesses strength of resistive touch technology, which is high accuracy. Accordingly, the panel senses almost all types of objects in addition to fingers, such as pens and even fingernails.

Optical touch panel has infrared ray sensors placed around the panel edge which recognizes the touch of a finger or other input devices. The technology is appropriate for multi-touch and can be applied to large panels at minimal added cost.

The 21.5-inch LCD monitor touch panel developed by LG Display is the first panel to have three infrared ray sensors, as opposed to two found in currently available optical touch panels. The result is significantly enhanced touch performance. The product demonstrates more than 95% accuracy, whether the screen is touched with a 3mm ballpoint pen or the multi-touch feature is used to zoom in, zoom out or rotate images.

With existing optical touch LCD panels, the infrared ray sensor is placed on a separate glass before being attached to the LCD module. In contrast, the latest product from LG Display has a simplified structure in which the sensor is embedded in the LCD module. As a result, luminance is enhanced by 10%, panel weight is lowered by 1 kilogram, and the bezel is just 11 millimeters wide (down by 45%) and 20 millimeters thick (down by 20%), thereby enabling better picture quality with slim and compact design.

Reflective of its superior technology, the product is the first monitor panel with touch function to receive Windows 7 Touch Logo certification. Mass production of the Full HD 21.5-inch LCD monitor touch panel is scheduled to begin in the third quarter.

LG Display CTO, Dr In Jae Chung said, "Touch accuracy and enhanced performance are vital for expansion of the touch panel market. The optical touch panel developed by LG Display responds to market needs by delivering world leading touch performance. Demand for touch panels is gradually expanding from small mobile gadgets to larger devices. LG Display will lead the market trends by expanding the touch function to IT applications such as notebook PCs and monitors."
