專利摘要 |
A light sensing circuit for solving the problem of low reliability in illumination detection includes a photo transistor having a gate, a drain and a source; a first transistor electrically connecting between the gate and source of the photo transistor; a first capacitor electrically connecting between the gate and the drain of the photo transistor; a second transistor electrically connecting with the drain of the photo transistor, the first capacitor, and a data signal; a second capacitor electrically connecting between the source of the photo transistor and a ground contact; a third transistor electrically connecting with the photo transistor, the first transistor, and the second capacitor; and a switch adapted to alternatively connect the third transistor with a buffer or a zero signal. A control method of the above light sensing circuit is also disclosed. Therefore, the above identified problem can be surely solved.
