Abstract
Disclosed in embodiments of the present disclosure are an analog-to-digital conversion circuit, an integrated chip, a display device, and an analog-to-digital conversion method. A first conversion circuit converts an original analog signal to obtain a digital signal of a first bit width; a voltage division circuit performs voltage division on a first-level analog signal to obtain a second-level analog signal, the first-level analog signal being an original analog signal or a second-level analog signal obtained by a previous voltage division circuit adjacent to the voltage division circuit; a second conversion circuit converts the received second-level analog signal according to a preset algorithm to obtain a second digital signal of a second bit width; and a control calculation circuit obtains a target digital signal of a third bit width according to the first digital signal and the second digital signal.
