A circuit and a method for driving pixels of an organic light-emitting display are provided. The circuit comprises a thin-film transistor having a source terminal connected to a voltage source, a storage capacitor having a first terminal connected to a gate terminal of the thin-film transistor, and an organic light-emitting diode having a cathode connected to a ground. The gate terminal and a drain terminal of the thin-film transistor are connected in a clamping phase and a reverse phase. A second terminal of the storage capacitor is connected to the ground in the clamping phase, and is connected to a data line in a light-emitting phase and in the reverse phase. An anode of the organic light-emitting diode is connected to the drain terminal of the thin-film transistor in the light-emitting phase and in the reverse phase.

Method for driving pixels of an organic light emitting display

An organic electro-luminescence display apparatus including a substrate, data lines and scan lines, a plurality of first, second and third organic electro-luminescence units, at least one first source driver, second source driver and third source driver and a gate driver is provided. Data lines and scan lines are disposed on the substrate to define a plurality of pixel areas. Each first, second, and third organic electro-luminescence unit is disposed in corresponding pixel area. Each first, second, and third organic electro-luminescence unit is electrically connected with one of the data lines and scan lines correspondingly. Each source driver is disposed at one side of the substrate. The data lines electrically connected with the first, second and third organic electro-luminescence units are electrically connected with corresponding source drivers. The gate driver is disposed at another side of the substrate and electrically connected with the scan lines. The luminous efficiency can be enhanced.
