Abstract
The present invention discloses a low-power driving control method of light sensing touch panel, which comprises the following steps: measuring the ambient light field intensity of the light sensing touch panel, and outputting a light field signal; outputting an amplification signal adapting to a touch signal according to the intensity of the light field signal; amplifying the touch signal according to the amplification signal, and driving the light sensing touch panel. The present invention further discloses a light sensing touch panel. The light sensing touch panel and the low-power driving control method thereof according to the present invention can reduce the power consumption of the touch panel without affecting the touch sensitivity.
