Abstract:
A display device includes a data mapping unit for extracting a minimum value among three-color input data which respectively correspond to red, green, and blue, determining white color output data by multiplying the extracted minimum value by a gain ratio, and determining red, green, and blue color output data respectively by subtracting the white color output data from the three-color input data; and a gain adjustment unit for determining the gain ratio to minimize a standard deviation respectively for the white color output data and the red, green, and blue color output data.
Abstract:
A method of driving a display panel that includes first and second display-regions includes: determining maximum luminance data among first data including first red data, first green data, and first blue data for the first display-region, calculating a threshold gray-level based on a luminance gain, a gray-level of the maximum luminance data, and a gamma value for the display panel, selecting a smaller value between the threshold gray-level and a maximum gray-level as a gain determination gray-level, calculating a compensation gain obtained by dividing the gain determination gray-level by the gray-level of the maximum luminance data, generating first compensated data by applying the compensation gain to the first data, displaying a first-image in the first display-region based on the first compensated data, and displaying a second-image in the second display-region based on second data including second red data, second green data, and second blue data for the second display-region.

Abstract:
An image processing device includes an image determiner which determines whether an image data is a still image or a motion picture image, a first compensator which gradually changes a scaling ratio of the image data of which a center part is fixed and a second compensator which divides the image data into a plurality of sub-image data and change a scaling ratio of the sub-image data.
Abstract:
A 3-dimensional (3D) flat panel display with a built-in touch screen panel includes a first substrate, a plurality of pixels on the first substrate, a plurality of first electrode patterns spaced apart from one another at a first predetermined interval along a first direction, the plurality of first electrode patterns for driving the plurality of pixels, a second substrate positioned to face the first substrate, and a plurality of barrier patterns formed on an outer surface of the second substrate and spaced apart from one another at a second predetermined interval along a second direction, intersecting the first direction. At least one of the plurality of first electrode patterns and at least one barrier pattern of the plurality of barrier patterns serve as electrodes for the built-in touch screen panel.
