摘要： Embodiments of the disclosure relate to a display compensation system and a display panel compensation method. Specifically, it is possible to enhance the luminance uniformity of the display panel by generating a current temporary shift voltage by adding a unit offset voltage to a previous temporary shift voltage, generating modified image data by compensating for image data based on the current temporary shift voltage, driving the display panel based on the modified image data, and reducing the luminance difference value which is the difference between the maximum luminance data and the minimum luminance data for the display panel.

摘要： A display device includes a display panel on which gate lines, data lines and subpixels are disposed; a gate driving circuit which drives the gate lines; and a data driving circuit which drives the data lines. Each of the subpixels includes: a light emitting device; a second transistor which has a first node, a second node that is a gate node, and a third node electrically connected to the light emitting device, and drives the light emitting device; a first transistor electrically connected between the third node and the data line; a third transistor electrically connected between the first node and the second node; and a fourth transistor electrically connected between the third node and the light emitting device. The third transistor performs a turn-off operation later than the first transistor, so that a voltage applied to the third node is transmitted to the second node via the first node.
