Title: TOUCH CONTROL SUBSTRATE AND TOUCH CONTROL DISPLAY APPARATUS
Abstract:
A touch control substrate and touch control display apparatus, said touch control substrate comprising: a light source (70); an optical transmission panel (10) arranged on a light-emitting side of said light source (70); a flexible substrate (24), comprising a flexible base (20) and a plurality of contact parts (40) which are arranged on said flexible base (20) and which face said optical transmission panel (10); and a light detection device (80) which is configured to detect emergent light emitted from said optical transmission panel (10). Said flexible base (20) is arranged opposite said optical transmission panel (10) so as to form a transparent spacer layer (31) therebetween, the refractive index of said transparent spacer layer (31) being lower than that of said optical transmission panel (10), and the distance from said flexible base (20) to said optical transmission panel (10) being greater than the height of said contact parts (40). The present touch control substrate uses a light-sensitive touch control technology, which compared to resistive or capacitive touch control technologies can more easily achieve touch control applications involving large dimensions; on the other hand, the touch control substrate can be applied within flexible display devices.
