DISPLAY DEVICE AND OPERATING METHOD THEREOF

摘要

A display device includes a display unit including pixels coupled to scan lines and data lines, a data driver which supplies a data signal to pixels through the data lines, a scan driver which generates a scan signal using a first scan voltage and a second scan voltage, and supplying the scan signal to the pixels through the scan lines, a processor which generates first scan voltage information by setting a first scan voltage level, based on an ambient temperature of the display device, a timing controller which generates a power control signal using the first scan voltage information and delta voltage information, and a power supply which generates the first scan voltage and a delta voltage using the power control signal, and generates the second scan voltage by dropping the delta voltage from the first scan voltage.
