A large-area display device can include a first individual display device including a plurality of first pixels, and a second individual display device including a plurality of second pixels and overlapping with the first individual display device in an overlapping area. The first individual display device is configured to be driven so that one or more pixels among the plurality of first pixels that are overlapped by the second individual display device in the overlapping area do not display an image, and the second individual display device is configured to drive one or more pixels among the plurality of second pixels located in the overlapping area to display an image.

Large-area display device and large-area display device driving system

A display device is disclosed that provides a compensation function using a movable sensor structure. The display device may sense luminance characteristics of subpixels and reduce or eliminate luminance deviations between subpixels without performing complicated sensing driving on subpixels of the display panel. The display device includes: a display panel including data lines, a gate lines, and subpixels, each of the subpixels including a light emitting device and a driving transistor; a housing protecting the display panel; a moving bar installed in the housing so as to be movable and moving at a front of a viewing surface of the display panel; sensor modules mounted on the moving bar to face the viewing surface of the display panel; and a sensing controller configured to control movement of the moving bar, control an operation of the sensor modules, and receive sensing values of each of the sensor modules.

Display device

Provided are a timing controller and a display device including the same. The timing controller in one embodiment includes a bit selecting unit, an error calculating unit, and a dithering unit. The bit selecting unit is configured to fix an m bit data value of n+m bit input image data for a plurality of subpixels as a fixed data value, where n and m are integers. The error calculating unit is configured to calculate an error between the fixed data value fixed by the bit selecting unit and the m bit data value of the input image data before fixed by the bit selecting unit. The dithering unit is configured to generate n bit output image data dithered to correct the error.
