Optical reflected touch panel and pixels and system thereof

An optical reflective touch panel, at least comprising:

• an Nth scan line, wherein N is a positive integer;
• an Nth data line;
• an Nth readout line;
• and
• a pixel comprising:
• a display circuit disposed at the junction of the Nth scan line and the Nth data line for controlling the display of the pixel;
• and
• a sensing circuit coupled to the display circuit for sensing a sensitization state of the pixel during a turned-on period and a turned-off period of a backlight module and outputting a digital signal to the Nth readout line to notify an optical reflective touch panel system that whether the pixel is touched or not.

An optical reflective touch panel system, comprising:

• a backlight module;
• and
• an optical reflective touch panel comprising at least an Nth scan line, an Nth data line, an Nth readout line, and a pixel, wherein N is a positive integer, and the pixel comprises:
• a display circuit disposed at the junction of the Nth scan line and the Nth data line for controlling the display of the pixel;
• and
• a sensing circuit coupled to the display circuit for sensing a sensitization state of the pixel during a turned-on period and a turned-off period of the backlight module and outputting a digital signal to the Nth readout line to notify the optical reflective touch panel system that whether the pixel is touched or not.
