Abstract: A pixel circuit for a display device provides enhanced performance by performing a partial threshold compensation during programming and performing further compensation independent of programming to achieve a short programming time while ensuring threshold compensation accuracy. The pixel circuit is operated in a relatively shortened duration first combined data programming and threshold compensation phase, and in a relatively prolonged duration second threshold compensation phase for improved compensation accuracy. During the combined programming and threshold compensation phase, a drive transistor is diode connected, and a data voltage is applied to a programming a capacitor that also stores a portion of a threshold voltage of the drive transistor. This permits a short programming time.

Abstract: A pixel circuit for a display device provides enhanced performance by performing a first threshold compensation phase that also operates to pre-charge a compensating storage capacitor, and then performing a further second threshold compensation combined with data programming during a shortened programming time. During the first threshold compensation phase, the threshold voltage of the drive transistor is stored in the compensating storage capacitor. During the combined data programming and second threshold compensation phase, the data voltage is stored in a programming capacitor, and the drive transistor threshold voltage is also stored in the programming capacitor.

Abstract: A pixel circuit compensates the threshold voltage variations of the drive transistor with an ultra-short one horizontal (1H) time, with additionally removing the possible memory effects associated with the light-emitting device and the drive transistor from the previous frame. An ultra-short 1H time (<2 ?s) is achieved via separation of threshold compensation of the drive transistor and data programming phases. The pixel circuit has a two-capacitor configuration, whereby a first capacitor is used for drive transistor threshold compensation, and a second capacitor is used to store the data voltage during a data pre-loading phase. Two transistors are employed to electrically connect the gate of the drive transistor to the second capacitor that stores the data voltage, wherein each transistor in this dual transistor configuration is controlled by a different control signal.

Abstract: A pixel circuit for driving a light-emitting device for a display device is operable in an initialization phase, a compensation phase, a data programming phase, and an emission phase. The one horizontal time is minimized while maintaining accurate compensation of the threshold voltage of the drive transistor, and the pixel circuit further employs a varactor to compensate for variations in the threshold voltage of the drive transistor and for parasitic capacitances that arise within the pixel circuit. A capacitance of the varactor varies with a voltage at a node N1 constituting an electrical connection during the compensation phase of the drive transistor, the light-emitting device, a storage capacitor, and the varactor. The use of the capacitance variation of the varactor accounts for a variation in the threshold voltage of the drive transistor and for parasitic capacitances in the pixel circuit. The varactor may be implemented as a thin film transistor that operates as a variable capacitor.

Abstract: A pixel circuit has enhanced performance by minimizing noise effects from the data and reference voltage lines. To prevent data line noise from interfering with the drive transistor gate voltage during emission, a triple gate isolation is used between the data voltage line and the gate of the drive transistor by which three transistors are connected between the data voltage line and the gate of the drive transistor. To further improve the isolation, one of the middle nodes of the triple gate farthest from the data voltage line is connected to one floating node that is connectable to a reference voltage during the threshold compensation phase. A first capacitor is used for the threshold compensation, and a second capacitor is used to scale the data voltage during programming. The threshold compensation and data programming operations are thereby independent of each other to minimize programming time.
