Pixel structure of organic electroluminescence device

摘要

A pixel structure of an organic electroluminescence device includes a scan line, and a data line, a bias line and a readout line on a substrate, a first switch device, a capacitor, a driving device, an organic light emitting device, a second switch device and a photo sensor device. The first switch device is electrically connected to the scan line and the data line. The capacitor is electrically connected to the first switch device and the bias line. The driving device is electrically connected to the first switch device, the capacitor and the bias line. The organic light emitting device is electrically connected to the driving device. The second switch device is electrically connected to the scan line and the readout line. The photo sensor device is electrically connected to the second switch device and the bias line.
