Abstract
A substrate with touch function includes a plurality of scan lines and at least a touch device disposed thereon. The touch device includes at least a power line, at least a readout line, a light sensing circuit and a voltage divider circuit. The power line and the readout line are disposed on the substrate. The light sensing circuit is electrically coupled to a (N+1)th of the power lines, an Nth of the scan lines and an Nth of the readout lines, wherein N is an integer. The voltage divider circuit has an output terminal and is configured to output a first voltage to the light sensing circuit through the output terminal thereof according to a degree of illumination thereon or a degree of capacitance change. A display using the aforementioned substrate is also provided.
