A method of processing an image signal includes: converting a source image signal into an image signal corresponding to a color space for a color gamut mapping; reducing a color gamut of the image signal; and mapping the image signal corresponding to colors within the reduced color gamut into an image signal corresponding to colors within a display color gamut, wherein the colors of the display color gamut are displayed by a display panel.

A method of driving a display panel includes providing a first clock signal having a first frequency and a second clock signal having a second frequency different from the first frequency. The method also includes providing a data signal of an N-th frame image to the display panel using the first clock signal, and providing a data signal of an (N+1)-th frame image to the display panel using the second clock signal. N is a natural number.

A method for reducing noise of a touch panel includes: generating a detection signal including at least one contact region; generating a combination noise region including at least a portion of the at least one contact region; and generating a final detection signal. The generating the final detection signal includes removing the combination noise region from the detection signal.

A 3D image display device includes a data receiving unit receiving frame data. The frame data includes left eye image data and right eye image data. An image modification unit generates modification image data corresponding to one of the left eye image data and the right eye image data. The modification image data corresponding to the left eye image data is based on left eye image data of a current frame and left eye image data of a next frame. The modification image data corresponding to the right eye image data is based on right eye image data of the current frame and right eye image data of the next frame. Utilization of the modification image data improves the display quality of moving objects in the 3D image display device.
摘要:
A touch sensor is installed inside a liquid crystal display panel to sense a touch operation and includes a light sensing part including a photodiode, a capacitance sensing part including a liquid crystal capacitor, and a sensing signal output part. The light sensing part generates a control signal corresponding to a variation in the amount of external light when the liquid crystal display panel is touched. The capacitance sensing part varies the control signal based on a variation in the capacitance of the liquid crystal capacitor when the liquid crystal display panel is touched. The sensing signal output part generates a sensing signal in response to the control signal and determines an output timing of the sensing signal.

In a method of processing data of a display apparatus, red, green and blue data are gamut mapped as red, green, blue and white data. The red, green, blue and white data are reconstructed by means of subpixel rendering to generate metameric sets dot pixels composed for example of one such dot pixel having red and green color components and another such dot pixel having blue and white color components such that when the metameric set dot pixels is lit up it produces a white colored region on the display apparatus and when un-lit it appears as contrastingly dark colored region on the display apparatus. By selectively forcing one metameric set of dot pixels to be un-lit, the method allows an immediately adjacent metameric set of dot pixels to be lit-up as a contrasting white region on the display apparatus.

A method of controlling a luminance of a light source is presented. The method entails generating red, green, blue and white data using red, green and blue data, applying a color weight according to contribution to luminance by each of the red, green, blue and white data to generate pixel luminance data, setting a luminance level of the light source based on the pixel luminance data, determining local information on a pure color block in a frame image by using the pixel luminance data, and adjusting the luminance level of the light source based on the local information on the pure color block. A display device that utilizes such method is also presented.
