Abstract

A display device comprises a display panel and a display panel driving unit. The display panel includes a switching element of a first type and a switching element of a second type different from thefirst type. The display panel driving unit drives the display panel. In a first mode, the display panel driving unit drives the switching element of the first type and the switching element of the second type with a high driving frequency. In a second mode, the display panel driving unit drives the switching element of the first type with the high driving frequency and the switching element of thesecond type with low driving frequency which is lower than the high driving frequency. In a third mode, the display panel driving unit drives the switching element of the first type and the switchingelement of the second type with the low driving frequency.

Description

technical field [0001] Example embodiments of inventive concepts relate to display devices. More particularly, example embodiments of inventive concepts relate to display devices that reduce power consumption and improve display quality. Background technique [0002] Generally, a display device includes a display panel and a display panel driver. The display panel includes a plurality of gate lines, a plurality of data lines, a plurality of emission lines and a plurality of pixels. Display panel drivers include gate drivers, data drivers, emission drivers and drive controllers. The gate driver outputs gate signals to gate lines. The data driver outputs data voltages to the data lines. The transmit driver outputs the transmit signal to the transmit line. The drive controller controls gate drivers, data drivers and emission drivers. [0003] When the image displayed on the display panel is a static image or the display panel operates in an always-on mode, the driving fre...
