Abstract

Disclosed are a device and method for driving a display supporting low power mode. A display driving device supporting a low power mode according to an aspect of the present disclosure that is capable of minimizing power consumption when driving in the low power mode includes a plurality of output buffers connected to data lines to precharge the data lines with a first data signal corresponding to a black image when a precharge horizontal line is driven in a display panel including a first region where a standby image is displayed and the second region where the black image is displayed, the precharge horizontal line being included in the second region, and a gamma voltage generator connected to the data lines to output the first data signal to the data lines when other horizontal lines other than the precharge horizontal line in the second region are driven.

Description

technical field [0001] The present disclosure relates to a display device, and more particularly, to a display driving device and a display driving method. Background technique [0002] With the development of the information society, demands for display devices for displaying images have increased in various forms. According to such demands, various types of display devices such as organic light emitting display devices (OLEDs) and the like as well as conventional liquid crystal display devices (LCDs) are being used. [0003] The display device described above is also applied to mobile terminals such as mobile phones, smart phones, tablet computers, laptop computers, and wearable devices. Such as figure 1 As shown, a recently developed mobile terminal supports a low power mode such as an always on display (AoD) mode, and in the low power mode, when the mobile terminal is not in use, the user-designated Standby image 110 such as a clock, weather or calendar. [0004] Whe...
