A driver circuit with device variation compensation function and an operation method thereof are provided. The driver circuit includes a pull-up switch unit, an isolating switch and a pull-down switch unit. A first terminal of the pull-up switch unit is coupled to a first voltage. A second terminal of the pull-up switch unit is coupled to an output terminal of the driver circuit. A first terminal of the isolating switch is coupled to the second terminal of the pull-up switch unit. A first terminal of the pull-down switch unit is coupled to a second terminal of the isolating switch. A second terminal of the pull-down switch unit is coupled to a second voltage. The pull-down switch unit has a device variation compensation function.

Driver circuit with device variation compensation and operation method thereof

A transistor array substrate includes a substrate, a pixel array, a plurality of resistors, and a plurality of semiconductor transistors. The pixel array, the resistors, and the semiconductor transistors are all disposed on the substrate. The pixel array includes a plurality of scan lines. Each resistor is electrically connected to one of the scan lines, and each semiconductor transistor is electrically connected to one of the scan lines and one of the resistors. The scan lines can receive a first voltage and a second voltage. The second voltage is higher than the first voltage.
