Title:
LASER TOUCH PANEL, DISPLAY DEVICE, DISPLAY SYSTEM AND LASER TOUCH METHOD
Document Type and Number:
WIPO Patent Application WO/2018/045745
Kind Code:
A1
Abstract:
A laser touch panel (100), a laser touch display device (10), a laser touch display system (30) and a laser touch method for the laser touch panel (10). Said laser touch panel (100) comprises a first conductive layer (111), a second conductive layer (131) and a photoinduced resistive change material layer (120). The photoinduced resistive change material layer (120) is provided between the first conductive layer (111) and the second conductive layer (131), and is electrically connected to the first conductive layer (111) and second conductive layer (131); the photoinduced resistive change material layer (120) is configured so as to undergo resistive change at a touch location that is irradiated by a laser. By means of the laser touch panel (100), long-distance laser touch of the display device (10) may be achieved.
