Problems solved by technology

[0008] However, the CFL type LCD creates a problem in that the color gamut changes due to color mixing caused by the sequential driving method of the RGB backlight, compared to the general LCD.
In other words, when the LC does not respond within a fixed time and the grayscale is not normally rendered, the color components of the next sequence are interfered by the color components of the previous sequence, thus mixing colors

Embodiment Construction

[0041] Hereinafter, exemplary embodiments will be described in more detail with reference to the accompanying drawings.

[0042] In the following description, the same reference numerals are used for the same elements described in different figures. Features such as detailed structures and elements are defined in the description to assist in a comprehensive understanding of the exemplary embodiments. Thus, it will be apparent that the exemplary embodiments may be practiced without these specifically defined features. Also, functions or elements known in the related art are not described in detail so as not to obscure the exemplary embodiments with unnecessary detail.

[0043]Exemplary embodiments can be described that since the image display device can work in the KRGB (or WRGB) mode in the experiment and is beneficial to improve color mixing, the image display device operates in the KRGB (or WRGB) mode in GRKB (or GRWB) mode. sequence to achieve a single-frame image, while ...

Abstract

An image display apparatus and method are provided. The image display apparatus includes an image analyzing unit which inserts an insertion frame into an image of a color sequence and outputs an image of a color sequence in which the insertion frame is inserted, and changes a position of the insertion frame based on at least one dominant color and outputs an image in which the position of the insertion frame is changed, a display panel which receives the image of the color sequence, in which the insertion frame is inserted, from the image analyzing unit and displays the received image, and a backlight unit which receives information for the color sequence, in which the insertion frame is included, from the image analyzing unit and provides light of a color corresponding to the color sequence, in which the insertion frame is included, according to the received information.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to Korean Patent Application No. 10-2012-0003177 filed in the Korean Intellectual Property Office on Jan. 10, 2012, the entire disclosure of which is incorporated herein by reference. technical field [0003] An apparatus and method according to an exemplary embodiment relate to an image display apparatus and method, and more particularly, to an apparatus capable of detecting a dominant color from an input image (ie, a unit frame image) and adapting itself according to the detection result An image display apparatus and method for implementing a sequence of colors can be varied. Background technique [0004] A liquid crystal display (LCD) as an image display device is a display device that applies an electric field to a dielectrically anisotropic LC layer located between two substrates, adjusts the amount of light transmitted to the substrates by controlling the intensity of the electric...
