Abstract
A display apparatus, an adjustment method and a formation method are provided in the present disclosure. The adjustment method includes recording a voltage value inputted to the first power signal line as a value A, where the value A is an actual voltage value of the first power signal line when the display panel is at the first target brightness level and the drive transistor operates in a saturation region; inputting the value A to the first power signal line in the display panel, reading a first actual data voltage value on a data line in the display panel at this point, and re-finding a first actual grayscale value corresponding to the first actual data voltage value from the gamma curve; and programming the value A, the first actual data voltage value and the first actual grayscale value corresponding to the value A into the drive chip.
