Problems solved by technology

[0004] Regarding the correction of mura, the method of correcting only the mura area detected by capturing the pattern image may require a lot of computation, and thus may increase the time period for correcting mura
In addition, when correcting the mura correction, it is necessary to perform many calculations to correct only the mura area generated by capturing the pattern image to detect the mura, and there is a problem that the mura correction time is prolonged
Additionally, the use of a high-resolution camera to remove the moiré pattern when capturing the pattern image may result in an increase in the price of the display correction device

Abstract

This article relates to a display device, a display correction device, a display correction system, and a display correction method. The display correction system includes: a display device for displaying a pattern image; a camera for photographing the displayed pattern image; an image analysis unit for calculating the RGB value of the photographed pattern image; and a characteristic correction unit for calculating The average of the RGB values ​​and the RGB value of each pixel are used to generate correction data for causing each pixel to display the calculated average.

Description

technical field [0001] Embodiments of the present disclosure relate to a display device for correcting characteristics of a displayed image, a display correction device, a display correction system, and a display correction method. Background technique [0002] As liquid crystal display devices (LCDs) become larger and curved, the size and frequency of occurrence of mura defects (ie, contrast type defects and image quality distortions) increase. The term mura means smudge in Japanese, which means a defect in which the shape of a point, line, or plane in a certain area is displayed differently in brightness or color from a surrounding area when the entire screen is displayed in a constant gray scale. [0003] Mura may be generated during the process of implementing an LCD panel in a display device or during the process of bending a flat LCD panel into a curved LCD panel. Specifically, mura may be generated by the uniformity of liquid crystal thickness, pressure distribution,...
