A display panel driver includes a storage unit configured to store an align pattern and a timing controller configured to output align image data based on an align control signal provided from a facility driver during a mechanism assembly process of a display panel. The align pattern includes an align mark, and the align image data includes the align pattern.

Display panel driver and display device including the same

A method of driving a liquid crystal display panel is provided. The liquid crystal display panel includes: a liquid crystal display pixel including a liquid crystal structure including a pixel electrode, a liquid crystal layer, and a common electrode; a switching transistor connected between the pixel electrode of the liquid crystal structure and a data-line; and a storage capacitor connected to the pixel electrode of the liquid crystal structure. The method includes: calculating an accumulated driving time of the liquid crystal display panel by accumulating a driving time of the liquid crystal display panel; determining whether or not the accumulated driving time has reached a deterioration reference time; and when the accumulated driving time is determined to have reached the deterioration reference time, changing a gate-off voltage applied to a gate terminal of the switching transistor and a common voltage applied to the common electrode.

Method of driving a liquid crystal display panel and liquid crystal display device employing the same

A display device includes: a display panel comprising a display area configured to display an image, wherein the display area includes a measurement area including a plurality of sub-measurement areas, and each of the plurality of sub-measurement areas includes a plurality of pre-map areas; a data driver configured to provide data voltages to the display panel; a signal controller; and a common voltage generator configured to provide a common voltage to the display panel, wherein an afterimage reduction mode is driven to change a level of the common voltage provided by the common voltage generator when the determined pre-map areas are adjacent to each other.
