Abstract
A display panel includes data lines and scanning lines in a display region, and a demultiplexer in a non-display region. The demultiplexer includes m branches. m is an integer. m≥2. Each branch includes a switching transistor which includes a first electrode coupled with an input terminal of the demultiplexer, a second electrode coupled with one of the data lines, and a control electrode for receiving a switching control signal. The demultiplexer includes a first demultiplexer including a compensation transistor, of which first and second electrodes are short-circuited. The compensation transistor is coupled with the data line and has a control electrode for receiving a compensation control signal. The compensation control signal received by the compensation transistor in the branch has one functional rising edge in a period during which the scanning line provides an effective level signal once.
