Abstract
An OLED display is proposed. The OLED display includes a gate driver for generating a scanning signal, a source driver for generating a data signal, and a plurality of cells arranged in an array. Each cell includes a first transistor for delivering the data signal when receiving the scanning signal, a second transistor for generating a driving current based on a voltage difference between a first supply voltage signal and the data signal, a storage capacitor coupled between the first transistor and an output end of the driving circuit, for storing the data signal, an organic light emitting diode for generating light based on the driving current, an infrared emitting layer for producing infrared ray, and an infrared sensitive layer for sensing the infrared ray reflected by an object.
