摘要： This disclosure provides systems, methods and apparatus for OLED control circuits. In some implementations, the OLED control circuit can be configured to reverse the bias of the OLED without the use of a dedicated initialization voltage. A low voltage data signal applied on a data line can be used to drain voltage from the anode of the OLED through a diode-connected transistor. A high voltage data signal applied on the same data line can be used to store a reference voltage on a storage capacitor, where the reference voltage is also a function of the threshold voltage of a driving transistor of the OLED control circuit. The stored reference voltage can be used to compensate for the threshold voltage of the driving transistor when the OLED is energized by a current, so that the current is independent of the threshold voltage of the driving transistor.

摘要： This disclosure provides apparatuses and methods of manufacturing apparatuses including thin film transistors (TFTs) and storage capacitors. An apparatus can include a substrate, a TFT, a storage capacitor adjacent to the TFT, and a common electrode. The storage capacitor can be substantially transparent to increase aperture ratio of a display device. The storage capacitor can include an insulating layer between a first transparent electrode and a second transparent electrode. The TFT can include a gate electrode, a gate insulating layer, an oxide semiconductor, source and drain electrodes, and a dielectric layer. The oxide semiconductor can be formed out of the same layer as the first transparent electrode, and the common electrode can be formed out of the same layer as the oxide semiconductor or the source and drain electrodes.
