Embodiment Construction

[0025] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be directly on the other element or layer. or layer, directly connected to or coupled to other elements or layers, or intervening elements or layers may be present.

[0026] It will be understood that although the terms "first", "second", etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.

[0027] The terminology used herein is for the purpo...

Abstract

A display device includes a plurality of pixels. The first pixel group of pixels displays a first grayscale image based on the first gamma curve during three subframe periods among consecutive first to fourth subframe periods; and during the first to fourth subframe periods During the remaining one subframe period in the fourth subframe period, the second grayscale image is displayed based on the second gamma curve. The second pixel group of pixels displays a third grayscale image based on the first gamma curve during three subframe periods among the first to fourth subframe periods; and during the first to fourth subframe periods The fourth grayscale image is displayed based on the second gamma curve during the remaining one of the subframe periods. The subframe period during which the first pixel group displays the second grayscale image is different from the subframe period during which the second pixel group displays the fourth grayscale image.

Description

technical field [0001] The present disclosure relates to a display device and a method of driving the same. More particularly, the present disclosure relates to a display device capable of improving display quality and a method of driving the same. Background technique [0002] Generally, a liquid crystal display includes: upper and lower substrates, each having a transparent electrode; liquid crystal injected between the upper and lower substrates; and upper and lower polarizers arranged on the outer surfaces of the upper and lower substrates, respectively. polarizer. The liquid crystal display changes the alignment of liquid crystals between an upper substrate and a lower substrate to control transmittance of light passing through the liquid crystals. [0003] The liquid crystal display operates in a horizontal electric field mode or a vertical alignment mode. In the vertical alignment mode, liquid crystals are aligned in a direction substantially perpendicular to the s...
