Abstract:
A display device includes a display panel, a scan driver that provides a scan signal to the display panel, a data driver that provides a data signal to the display panel, a driving controller that controls the scan driver and the data driver, a temperature sensor that senses local temperatures of local regions of the display panel using a temperature sensor and generates temperature sensing information, a current sensor that senses driving currents of the local regions and generates current sensing information, and a sensing controller that selects sensing target regions based on respective degradation degrees of the local regions, determines sensing priorities between the sensing target regions, and controls the sensing target regions to be sequentially sensed only during a sensing execution time according to the sensing priorities between the sensing target regions.
Abstract:
An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a plurality of pixels, a luminance measuring unit, a current measuring unit, and a compensation data generator. The luminance measuring unit measures the luminance of each pixel and generates luminance information corresponding to the measured luminances. The current measuring unit measures the current output from each pixel and generates current information corresponding to the measured currents. The compensation data generator generates compensation data including a compensation value for each pixel based on the luminance information and/or the current information.
