Abstract
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.
