An apparatus for correcting an image according to the disclosure includes a color difference detector displaying color difference test images and obtaining color difference recognition information of a user with respect to the color difference test images, a color correction data generator displaying color correction test images based on the color difference recognition information and generating color correction data for correcting color coordinates using the color correction test images, and an image correction data generator generating image correction data for correcting color coordinates for each grayscale of the image displayed by the display device based on the color difference recognition information and the color correction data.

Apparatus and method for correcting image

A display device includes a display panel including a pixel that includes sub-pixels for emitting light in respective colors, and a driver configured to adjust a current amount flowing through the sub-pixels and to adjust an emission duty of the sub-pixels, drive one sub-pixel among the sub-pixels having a luminance with a first current amount and with a first emission duty when a color coordinate of an image expressed by the pixel is within a reference color space, and drive the one sub-pixel having the luminance with a second current amount that is greater than the first current amount and with a second emission duty that is less than the first emission duty when the color coordinate is outside of the reference color space.

Display device capable of high color reproduction and method of driving display device

A sealing member of a rolling bearing is formed in a structure in which an elastic sealing portion is attached to a frame, and the elastic sealing portion may comprise a first sealing portion formed on one end portion of the frame and a second sealing portion formed on the other end portion of the frame. The first sealing portion may be inserted into and mounted to a coupling groove formed in the second member, and the second sealing portion may comprise an axial sealing lip extending in the axial direction from the frame and a radial sealing lip extending in the radial direction from the frame. The axial sealing lip and the radial sealing lip of the second sealing portion may be positioned adjacent to the first member and may be configured to perform a sealing in a non-contact manner.
