A touch-sensing display panel (1), comprising: an LCD unit (6) including a backlight unit (28) and a plurality of image-forming pixel elements (10) arranged in a central region (12); a light emitter (7) emulated by passing light through a pixel element of a first selected portion (271) of a peripheral region (11) of the LCD unit, said emitter including a first quantum dot structure (71) connected to receive excitation light from said backlight unit so as to emit light at longer wavelength than said excitation light; a planar light guide (2) having a front surface (3) forming a touch-sensing region and an opposite rear surface (4) facing the LCD unit, said light guide being connected to receive emitter light for propagation therein through total internal reflection; a light detector (8) connected to receive light from the light guide. |
