Abstract: Disclosed are a device and method for sensing the threshold voltage of a driving TFT included in an organic light emitting display so that a change in the threshold voltage of the driving TFT is sensed during real-time operation by reducing sensing time. First and second sensing voltages are obtained by fast sensing in the TFT linear region, and a change in the threshold voltage of the driving TFT is obtained based on the sensing ratio between the sensing voltages. Thus, a number of processes for deducing a change in threshold voltage, i.e., programming, source node resetting, sensing, and sampling, may be performed during the vertical blanking interval. That is, it is possible to sense a change in the threshold voltage of the driving TFT DT during real-time operation, without the need of arranging a time during power-on or power-off in order to sense a threshold voltage change, thereby improving compensation performance.

Abstract: A power supply circuit, an array substrate and a display device. The power supply circuit includes a plurality of power wires, each providing a voltage to a row of pixel units. The plurality of power wires include at least a first power wire and a second power wire, between which at least one logical AND circuit is disposed. The logical AND circuit electrically econnects the first power wire with the second power wire when high level voltages are output by the first power wire and the second power wire simultaneously. By disposing the logical AND circuit between the power wires, the two power wires are electrically connected with each other when high levels are output simultaneously. As a result, voltages at connection points of two rows of power wires approximate to each other, voltage differences among different rows of pixel units are reduced, and therefore the phenomenon of luminance nonuniformity in a display caused by different voltage drops of different rows of pixel units is improved. The power supply circuit is simple in structure and low in cost.

A precharge signal PC is input into the precharge circuit (250, 250a). The D/I conversion section has two output blocks internally thereof, and a role for storing and outputting current is changed every frame to enable securing a period for driving a pixel longer. Further, at the time of driving, in the precharge circuit (250, 250a), current driving is carried out after a voltage corresponding to output current has been applied to the pixel, and therefore, the pixel can be driven at high speed. Thereby, output current of high accuracy can be supplied to digital image data to be input, and even where an output current value is low, the current load device can be driven at high speed.
