摘要： An AMOLED driving circuit and driving method adds an additional switching transistor to a 2T1C driving circuit. An additional switching transistor is connected to the high voltage source, a scan line and a node connected a source terminal of a driving transistor of the 2T1C driving circuit and the light-emitting device. The additional switching transistor and an original switching transistor of the 2T1C driving circuit are activated when the scan line outputs high voltage. At the time, a low voltage of a PWM voltage is added to the high voltage source not to drive the driving transistor, and a storage capacitor stores a voltage of the image data signal. When the two switching transistors turn off and a high voltage of the PWM voltage is provided to the high voltage source, the driving transistor is driven to generate a driving current to the light-emitting device.

摘要： A shift register includes multiple stages connected with each other in succession. The shift register stores the threshold voltage of an amorphous silicon thin-film transistor in a capacitor. During operation, the bias applied to the transistor is adjusted according to the threshold voltage stored in the capacitor.

摘要： A dual display device has pixels and each pixel includes a transparent substrate, an active driving circuit, a top organic LED, a bottom organic LED, an insulation layer that covers the active driving circuit and the bottom organic LED, and a contact hole. A connection element covers the insulation layer, the top organic LED is deposited on the connection element, and the anodes of the two LEDs electrically connect to the active driving circuit through the contact hole by the connection element. Hence, each pixel forms a structure that two organic LEDs stack together on the transparent substrate and the top and bottom organic LEDs can be driven respectively so as to achieve the dual display device.
