Multi-tactile display i.e. LCD, screen for e.g. computer, has conversion layer converting infrared light into visible light, and zone including transistor that detects visible light and outputs signal based on transistor`s activation

摘要

The screen has a light conversion layer (CONV) arranged between upper and lower transparent substrates (41, 42) to convert an infrared light received by the substrate (41) into a visible light, and an infrared light source (IRS) i.e. infrared LED, enlightening a portion of the substrate (41). The substrate (42) has a pixel zone with a thin film transistor that activates a transparent pixel electrode. The zone has a light detection thin film transistor (TFTSS) i.e. optical sensor, that detects the visible light and outputs a light detection signal based on activation of the transistor (TFTSS). An independent claim is also included for a method of stimulating a multi-tactile function display.
