The display device includes: a display unit including a plurality of pixels, a plurality of scanning lines connected to the plurality of pixels, and a plurality of data lines connected to the plurality of pixels; a scanning driving unit sequentially applying a grid to the plurality of scanning lines Pole conduction voltage; the data drive unit, in response to the gate conduction voltage, applies data signals to the plurality of data lines; the signal control unit generates image data signals according to the input image signals and synchronous signals, thereby converting them to forwarding to the above-mentioned data drive unit; and a unit information providing unit that provides unit information for indicating a position on a manufacturing process of a display substrate including the plurality of pixels to the above-mentioned signal control unit, and the above-mentioned signal control unit includes a plurality of units The standard data selects unit standard data corresponding to the unit information from the plurality of unit standard data, and generates the image data signal based on the selected unit standard data.

Description

technical field [0001] The present invention relates to a display device and a driving method thereof, and more specifically, to a display device and a driving method thereof capable of improving dispersion of production processes. Background technique [0002] A liquid crystal display (LCD), which is one of the representatives of display devices, includes a thin film transistor display panel with pixel electrodes, a common electrode display panel with common electrodes, and a dielectric barrier between the two display panels. Anisotropic (dielectric anisotropy) liquid crystal layer. The pixel electrodes are arranged in a matrix form and connected to switching elements such as thin film transistors (thin film transistor, TFT), so that data voltages are applied row by row. The common electrode is formed on the entire surface of the common electrode display panel, and a common voltage is applied thereto. From the circuit point of view, the pixel electrode, the common electro...
