Abstract

The disclosure provides a compensating circuit for overdriving a data signal of display device. The compensating circuit includes a memory circuit, an offsetting circuit and an overdriving value generator. The memory circuit stores a first offset gray value of a first frame period. The offsetting circuit receives the first offset gray value, a duty value of an emission driving signal and a current gray value of the data signal. The offsetting circuit generates a second offset gray value of a second frame period according to the duty value, the current gray value and the first offset gray value, and stores the second offset gray value into the memory circuit. The overdriving value generator generates an overdriving value for overdriving the data signal to generate a compensated data signal according to the second offset gray value and the current gray value.
