    摘要: A dithering system includes a linear transformer, a dither data generator, an adder and a shifter. The transformer linearly transforms M bit input data using a linear function having a predetermined gradient in order to generate and output M bit transform data. The dither data generator generates and outputs M−N bit dither data. The adder adds the M bit transform data and the M−N bit dither data to generate and output M bit correction data. The shifter cuts off the bottom M−N bits of the M bit correction data in order to generate and output the N bit output data. The dithering system and associated dithering method widely disperses an error generated due to a physical limit of a data bit that can be expressed by a low gray scale system throughout the entirety of the gray scales when high gray scale image data is converted to low gray scale image data. This is done without using a lookup table which avoids using valuable chip area. In addition, by utilizing a plurality of adders and shifters rather than a multiplier and divider, the number of required logic gates is remarkably reduced as well as reducing associated power requirements.

    摘要: A method and apparatus of compensating for a kick-back voltage to reduce the generation of flicker in a liquid crystal display (LCD). The method of compensating for a kick-back voltage includes correcting input pixel data using a kick-back correction function that meets a condition on which a response characteristic of a voltage detected from a pixel electrode of a liquid crystal cell for a positive input pixel signal and a response characteristic of a voltage detected from the pixel electrode of the liquid crystal cell for a negative input pixel signal become symmetrical without causing a saturation state on a basis of a kick-back voltage measured from an LCD panel to generate corrected pixel data, and driving the LCD panel using the corrected pixel data.

    摘要: A method of forming a capacitor includes the step of forming an electrode on an integrated circuit substrate wherein the electrode covers a first portion of the integrated circuit substrate and wherein the electrode exposes a second portion of the integrated circuit substrate. An etch masking pattern including a plurality of ions is formed on the surface of the electrode wherein the etch masking pattern exposes portions of the surface of the electrode. The exposed portions of the electrode are etched using the etch masking pattern as an etching mask so that recesses are formed in the surface of the electrode thereby increasing a surface area thereof. The etch masking pattern is removed, a dielectric layer is formed on the electrode including the recesses, and a conductive layer is formed on the dielectric layer opposite the electrode.
