Display apparatus, control method and compensation coefficient calculation method thereof

Abstract

A display apparatus, including a display panel which includes a light emitting element, a storage configured to store a plurality of compensation coefficients corresponding to a plurality of gray levels according to a parasitic capacitance of the light emitting element, and a processor configured to obtain a compensation coefficient from the plurality of compensation coefficients based on at leastone of a position of a scan line and a gray level of scan data, compensate the gray level of the scan data based on the obtained compensation coefficient, and drive the light emitting element based on the compensated gray level.

Description

technical field

[0001] Devices and methods consistent with example embodiments relate to a display device, a control method and a compensation coefficient calculation method thereof, and more particularly, a display device including a display panel including a self-luminous element and a driving method thereof. Background technique

[0002] Light emitting diodes (LEDs) are semiconductor elements that convert electrical current into light. Recently, LEDs have been increasingly used as display light sources, automotive light sources, and lighting light sources. In addition, high-efficiency LEDs that emit white light can be realized by using fluorescent materials or combining LEDs of various colors.

[0003] Parasitic capacitance can form between the p-n junctions of light emitting diodes. However, there is a problem of reducing the illuminance of a certain area due to the influence of parasitic capacitance. Contents of the invention
