Problems solved by technology

In addition, there is a problem that a separate color filter layer should be formed on the substrate, and the light transmittance of the color filter should be improved
However, if the color is expressed by such a continuous color driving method, the phenomenon of color cracking may occur depending on the human color recognition tendency
[0011] In other words, even if the liquid crystal is fully synchronized with the backlight during color driving of the CFL, because such figure 2 As shown in the LCD, the response speed of the liquid crystal is slower than that of the LED, so it is impossible to separate the colors accurately

Embodiment Construction

[0070] Hereinafter, exemplary embodiments will be described in more detail with reference to the accompanying drawings.

[0071] In the following description, the same reference numerals are used for the same elements when they are depicted in different drawings. Matters defined in the description, such as detailed construction and elements, are provided to help a comprehensive understanding of the exemplary embodiments. Thus, it is apparent that the exemplary embodiments can be carried out without these specifically defined matters. Also, functions or elements that are known in the related art are not described in detail since they would obscure the exemplary embodiments with unnecessary detail.

[0072] image 3 is a block diagram showing a display device 301 according to an exemplary embodiment.

[0073] Such as image 3 As shown in , a display device 301 according to an exemplary embodiment entirely or partially includes a timing controller 300, an image correction uni...

Abstract

A display apparatus and a driving method thereof are provided. The display apparatus includes an image analysis unit which analyzes a correlation of an image by comparing a current image and a previous image input prior to the current image, and determines a level of correction of the current image according to the analysis of the correlation, and an image conversion unit which converts pixel values of pixels of a unit frame having a specific color in the current image based on the level of correction, and outputs the pixel values.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2011-0101326 filed with the Korean Intellectual Property Office on Oct. 5, 2011, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] Methods and devices consistent with the exemplary embodiments relate to a display device and a driving method thereof, and more particularly, to a method that can improve color rendering (color rendering) by preventing color mixing of a color filterless liquid crystal display (CFL), for example. rendition) display device and its driving method. Background technique [0004] A liquid crystal display (LCD) refers to a display device in which an electric field is applied to a liquid crystal layer having an anisotropic dielectric constant and injected between two substrates. By adjusting the intensity of the electric field to adjust the amount of light passing through the su...
