摘要： The present invention relates to an uniformly active light emitting diode drive circuit. This invention provides a 3T1C circuit structure in the emitting pixel and an additional data capacitors connecting to all the pixels are picked out and located on one side of the display panel. In addition, the connecting lines to the OLED on every pixel are all collected to one end of a transistor Moc on the other side of the display panel. Through the arrangement, it is intended that the aperture ratio of the organic electroluminescent (OLED) device can be largely improved. Moreover, an additional by-pass current transistor in parallel with data capacitor (Cd) in a data generator region outside of the pixel array can by-pass the previous left current in the circuit and thus enhance the contrast ratio of the emitting pixel.

摘要： A pixel circuit related to an organic light-emitting diode (OLED) is provided. When signals having appropriate operating waveforms are supplied, the circuit configuration (6T1C) of the pixel circuit keeps a current flowing through an OLED unchanged when the Vth shift of the TFT for driving the OLED changes and eases the impact of a power supply voltage Vdd on the current. Thereby, the luminance uniformity of an OLED display adopting the OLED pixel circuit is greatly improved.

摘要： The main circuit of each stage of the high-reliability shift register circuit is composed of transistors, and the turn-on time for the four transistors are only 1˜2 pulse time within one frame time. Transistors construct an inverter circuit which continuously offers a high-level supply voltage that controls activities of transistors so as to continuously offer a low-level supply voltage to the first node and the output terminal such that avoids the first node and the output terminal being in a floating state. Besides, one of the transistor acts as a charging circuit that extends the lifetime of another transistor. This circuit avoids the affection on the behavior of the shift register circuit that is caused by an a-Si (amorphous silicon) TFT under a sustained stress.
