Patent ID: 8441600

Claim:
A driving method for a display having a mesh of scan and data lines and an array of pixels, each pixel including a lighting device, a driving transistor, a storage capacitor and a data transistor, wherein the driving transistor has a gate electrode and first and second source/drain electrodes, the storage capacitor having first and second terminals respectively connected to the gate electrode and the first source/drain electrode of the driving transistor, the second source/drain electrode of the driving transistor being connected to the lighting device, the method comprising: programming the pixel, including: disconnecting the first source/drain electrode of the driving transistor from a power supply source; respectively connecting the gate electrode of the driving transistor and the first terminal of the storage capacitor to a reference voltage, such that the reference voltage is respectively applied at the gate electrode of the driving transistor and the first terminal of the storage capacitor; asserting a scan signal on the scan line corresponding to the pixel so as to turn on the data transistor; and supplying a data signal from the corresponding data line via the data transistor to the second terminal of the storage capacitor, whereby the storage capacitor is charged under a voltage difference between the data signal and the reference voltage; and displaying the pixel, including: disconnecting the gate electrode of the driving transistor from the reference voltage; unasserting the scan signal corresponding to the pixel; and connecting the first source/drain electrode of the driving transistor and the second terminal of the storage capacitor to the power supply source, such that a power supply voltage of the power supply source is respectively applied at the first source/drain electrode of the driving transistor and the second terminal of the storage capacitor, the gate electrode of the driving transistor and the first terminal of the storage capacitor being at a common voltage level.
