Abstract

Provided are a display drive circuit, a display device, and a portable terminal including the drive circuit and the display device that prevent the occurrence of flicker. The display device includes: a display panel including a plurality of pixels, a plurality of data lines and a plurality of gate lines respectively connected to the plurality of pixels, and a display driving circuit configured to change the frame frequency of the display panel according to an operation mode, select A gamma curve corresponding to a frame frequency, wherein the selected gamma curve is one of a plurality of gamma curves set so as to correspond to different frame frequencies, and the display panel is driven based on the selected gamma curve.

Description

technical field [0001] The present disclosure relates to a display driving circuit, a display device, and a portable terminal including the display driving circuit and the display device. More particularly, the present disclosure relates to a display driving circuit, a display device, and a portable terminal including the display driving circuit and the display device, which can prevent the occurrence of flicker. Background technique [0002] Recently, smartphones or tablet personal computers (PCs) including ultra-high definition display modules are being released. In this regard, the display driver circuits process more data, and thus the amount of current used by the display driver circuits continues to increase. In order to increase battery life, internal circuits of portable electronic devices such as smartphones or tablet PCs may operate at low power. Therefore, there is a need for a display device that operates at low power and produces high quality images. [0003]...
