摘要： An apparatus for setting a common voltage include a screen generator, a flicker measuring part, a main controller and a read-only memory (“ROM”) programming part. The screen generator generates image data of a test screen. The flicker measuring part measures flicker on the test screen displayed on a display panel to which a common voltage corresponding to an estimated setting value is applied. The main controller calculates a measured flicker index from the measured flicker and compares the measured flicker index with a predetermined threshold value to determine a setting value corresponding to a flicker index of a plurality of calculated flicker indexes that is less than the threshold value. The ROM programming part writes the determined setting value to a ROM of a display module. Therefore, a common voltage is reestablished by the setting value, thus preventing flicker due to process variations.

摘要： An apparatus for driving a display panel includes a timing control part, a line memory part, a frame memory part and an image compensation part. The timing control part receives a horizontal synchronizing signal from an external system via a CPU interface process. The line memory part stores an image signal of an n-th frame in a line unit, based on the horizontal synchronizing signal. The frame memory part stores an image signal of an (n-1)-th frame based on the horizontal synchronizing signal. The image compensation part generates a compensated image signal of the n-th frame using the image signals of the n-th and (n-1)-th frames, which are respectively outputted from the line memory part and the frame memory part, based on the horizontal synchronizing signal. Accordingly, display quality in a CPU interface mode may be enhanced.

摘要： The present invention relates to a driving device for a liquid crystal display includes a gray voltage generator that generates first and second reference gray voltages, a common voltage generator that generates a common voltage, and a data driver that generates a data voltage on the basis of the first and second reference gray voltages and applies the data voltage to the pixels. The gray voltage generator includes a variable resistor unit that changes the first reference gray voltage according to the type of liquid crystal display. In this way, it is possible to manufacture a general-purpose IC capable of being applied to all types of liquid crystal displays, rather than a dedicated IC used for only a specific type of liquid crystal displays.
