Abstract
A photosensitive system, a display apparatus and a method for determining a position of a human eye, the photosensitive system comprises: photosensitive array devices arranged in an array, an amplification circuit, an analog-to-digital conversion circuit and a coordinate determining circuit. The photosensitive array device comprises a plurality of photosensitive triodes, each photosensitive triode converts an optical signal of an acquired image of the human eye into current signals, the amplification circuit performs a differential amplification on the current signals to obtain a plurality of voltage difference signals, the amplification circuit is a single-sampling amplification circuit or a dual-sampling amplification circuit, the analog-to-digital conversion circuit converts the voltage difference signals into digital signals, the coordinate determining circuit determines a digital signal with the minimum value from the digital signals, and determine the position of the human eye position according to the digital signal with the minimum value.
