Problems solved by technology

As a result, an overall 20% loss in brightness will result, reducing the color's expressiveness
[0006] Even if the optical design is based on the overall brightness of red R, green G and blue B, and the maximum gray voltage is set to 3.4V, there will still be a loss of brightness

Embodiment Construction

[0032] In order to enable those skilled in the art to practice the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the present invention can be embodied in different forms, and it is not limited to the embodiments described here.

[0033] In the drawings, the thicknesses and regions of layers are exaggerated for clarity. Throughout the specification, the same reference numerals are attached to the same elements, and it should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it means that it is located directly on the other element. , or there may be other components in between. In contrast, when an element is referred to as being "directly" on another element, it means that there are no intervening elements.

[0034] Hereinafter, a display device and a driving method thereof according to an embodiment of the...

Abstract

The invention relates to a display device and a driving method thereof. The device includes: a plurality of gate lines; a plurality of data lines crossing the gate lines for transmitting a grayscale voltage selected from a plurality of grayscale voltages as a data voltage corresponding to image data; and a plurality of pixels intersecting with the gate lines. The polar line and the data line are connected for receiving the data voltage. The pixels include first color pixels, second color pixels, and third color pixels. The first color pixel exhibits the maximum brightness by virtue of the applied first voltage having the maximum value among the grayscale voltages, and the second and third color pixels exhibit the maximum brightness by virtue of the applied second and third voltages, the second and the third voltage is less than the first voltage.

Description

technical field [0001] The present invention relates to a display device and a driving method thereof. Background technique [0002] Generally, a liquid crystal display includes two panels having a pixel electrode and a common electrode, and a liquid crystal layer with dielectric anisotropy interposed between the two panels. The pixel electrodes are in the form of an array, and are connected to switching elements such as thin film transistors to receive data voltages row by row. The common electrode is formed substantially on the entire panel, and receives a common voltage. From the perspective of the circuit, the pixel electrode, the common electrode and the liquid crystal layer between them form a liquid crystal capacitor, and the liquid crystal capacitor and the switching element connected to the liquid crystal capacitor form the basic unit of the pixel. [0003] A liquid crystal display forms an electric field in a liquid crystal layer by applying a voltage to two elec...
