Abstract

A display device is disclosed. The display device comprises: a display including a plurality of display modules; a display driving unit including a plurality of driving modules connected to each of the plurality of display modules; a storage for storing current control information according to the brightness of a display device; and a processor for calculating the maximum power amount available ineach of the plurality of display modules on the basis of the entire power capacity, which can be provided by the plurality of driving modules, and of the individual power consumption amount of each of the plurality of display modules, calculating a peak brightness level of each of the plurality of display modules on the basis of the calculated maximum power amount, and controlling, on the basis of the current control information, the plurality of driving modules such that each of the plurality of display modules has the corresponding peak brightness level.

Description

technical field [0001] The present disclosure relates to a display device and a driving method thereof, and more particularly, to a display device including a display composed of self-luminous elements driven by current and a driving method thereof. Background technique [0002] A light emitting diode (LED) is a semiconductor light emitting element that converts electric current into light. Since the brightness of light-emitting diodes has recently increased, light-emitting diodes are increasingly used as light sources for displays, light sources for vehicles, and light sources for lighting, and can be used by using fluorescent materials or by incorporating various colors of The light-emitting diodes are combined to realize white-emitting light-emitting diodes with excellent efficiency. [0003] As the current increases, such light-emitting diodes can display images with high brightness. [0004] Specifically, when using a display comprised of multiple LED display modules ...
