A planar light guide with a first refractive index has a front surface forming a touch-sensing region and an opposite rear surface facing the LCD unit. A plurality of light emitters are emulated by passing light from the backlight through pixel elements of first selected portions of a peripheral region of the LCD unit into the light guide for propagation therein through total internal reflection, and a plurality of light detectors are connected to receive light from the light guide."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch-sensing LCD panel","description":"A touch-sensing display panel, comprising an LCD unit including a backlight and a plurality of image-forming pixel elements arranged in a central region.
