Display device

A display device, comprising:

• a display region;
• a gate line and a data line which are crosswise arranged;
• a pixel array, arranged at a crossed region of the gate line and the data line and arranged in the display region;
• a gate driver, configured to provide a gate signal to the gate line;
• a test circuit, coupled to a first input line and a second input line respectively, wherein the first input line is configured to transmit a test signal, the second input line is configured to transmit a test control signal, and the test circuit is configured to provide the test signal to the data line based on the test control signal;
• and
• a data driver, comprising a first power line, a first transistor and a third input line, wherein the first power line is configured to supply an initial voltage to the pixel array, the first power line is coupled to the first input line via the first transistor, a gate of the first transistor is coupled to the third input line, the third input line is configured to transmit a pre-charge control signal, and the pixel array is configured to supply the initial voltage to each pixel in the pixel array based on the pre-charge control signal.
