摘要： A photo element includes a capacitor, a switch thin film transistor (TFT), a charge thin film transistor, and a photo thin film transistor. A voltage is charged to the capacitor through the charge TFT, and the output voltage of the capacitor is read through the readout line. The photo-induced current will affect the output voltage of the capacitor; therefore it is employed to determine whether the photo element is touched. Later, a reverse-biased voltage is applied to the photo TFT, such that the threshold voltage and sensitivity of the photo TFT can be maintained.

摘要： The gate of the first TFT in the present invention is discharged through the first TFT and the OLED in the compensation and data writing stage operation. As in cases that the usage time of the display pixel extends and the threshold voltage of the first TFT increases and the mobility thereof decreases, the voltage of the OLED increases, or the size of the display becomes larger to induce IR drop, the present invention enables to reduce the discharge voltage (charge current) to raise the gate voltage of the first TFT for compensating the OLED current drop. Meanwhile, the fifth TFT has characteristic of the threshold voltage increase. As the threshold voltage of the fifth TFT increases with usage time, the compensation of the OLED luminous efficiency drop can be realized.
