Patent ID: 8253664

Claim:
A display array, comprising: a substrate; a plurality of data lines disposed on the substrate; a plurality of scan lines disposed on the substrate for receiving scan signals respectively; and a plurality of display units, each corresponding to one set of the data and scan lines and comprising a switch transistor, a control unit, a driving transistor, a storage capacitor, and a light-emitting diode, wherein each control unit comprises a first transistor having a gate coupled to a first voltage source for receiving a fixed voltage, a drain coupled to a gate of the driving transistor at a first node, and a source coupled to a reference voltage source; wherein the storage capacitor has a first terminal coupled to the reference voltage source and a second terminal coupled to the gate of the driving transistor at the first node; wherein in each of the display units, a control terminal of the switch transistor is coupled to the scan line for receiving the corresponding scan signal, an input terminal of the switch transistor is coupled to the data line, and an output terminal of the switch transistor is coupled to the first node; wherein in each of the display units, the gate of the first transistor is physically separated from the control terminal of the switch transistor; and wherein, in each display unit, the control unit controls light-emitting intensity of the light emitting diode.
