INTERATCTIVE DISPLAY SYSTEM |
摘要 |
TFTs (10) within a display device (1) are intentionally made sensitive to radiation from an external light source (12), for example by making a pin-hole(34) in the so-called black-matrix layer (33). The voltage across the pixel (8) or associated capacitor drops on illumination. In sensing this voltage drop just before refreshing the pixel content during 5 the next refresh cycle, it is possible to distinguish between an intentionally illuminated pixel (8) or pixel patterns (37, 38) and a non-illuminated pixel (8).
