Abstract: A display device includes: a target pixel; observation target pixels located adjacent to the target pixel; and a grayscale corrector for converting an input grayscale value corresponding to the target pixel with reference to observation target grayscale values corresponding to the observation target pixels. The grayscale corrector includes: a light emitting pixel counter for providing a number of light emitting pixels by counting a number of observation target pixels that exceeds a reference value; and a grayscale converter for providing a converted grayscale value by converting the input grayscale value, based on the number of light emitting pixels.

Abstract: There is provided a method for setting black data of a display device and a display device employing the same. In the method for setting black data of the display device including a display unit for displaying an image corresponding to data, the method includes: applying data having a test voltage to the display unit; measuring a luminance of a test image displayed in the display unit; and when the measured luminance is a reference luminance or less, setting first black data, based on the test voltage.

Abstract: A flexible circuit film including a first flexible film, a second flexible film facing the first flexible film, and a plurality of wirings arranged between the first flexible film and the second flexible film. The wirings have different widths and bend in different directions, and a guide film including a material more rigid than the first and second flexible films is arranged on ends of the first flexible film. The guide film includes a tear-preventing portion overlapping with a bending portion of a shortest one of the wirings while covering portions of an inner edge near inner corners of a U-shaped flexible circuit film.

Abstract: A flexible circuit film including a first flexible film, a second flexible film facing the first flexible film, and a plurality of wirings arranged between the first flexible film and the second flexible film. Each of the wirings has a first portion extending in a second direction from a first terminal portion to a first connection part, a second portion extending in a first direction different from the second direction from the first connection part to a second connection part, and a third portion extending in a direction opposite to the second direction from the second connection part to a second terminal portion.
