    摘要: A method and system for adjusting a gray-scale level of an LCD device. The method includes: checking a default gray-scale value A; comparing default brightness value YA with a target brightness value YX; inputting a trial gray-scale value B; and outputting a target gray-scale value X. The method employs a preselected Similarity of Triangles technique. The system employs a image-capturing unit determining screen brightness and a control unit using a preselected Similarity of Triangles technique to adjust the gray-scale level of a connected display device, reducing a single-screen-capture gray-scale level adjustment interval to about 1.8 to 2.1 seconds.

    摘要: In a driving method of a display apparatus using a driving circuit, when an image signal is a film image signal, first, second, and third original image signals are extracted based on the film image signal. Then, a first compensation image signal is generated based on first and second original image signals, and a second compensation image signal is generated based on second and third original image signals. The first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are sequentially output to have a driving frequency higher than an input frequency. In addition, the first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are output i, k, j, and k times, respectively. Thus, a trembling phenomenon perceived by a viewer of a film image may be prevented.

    摘要: A timing controller includes an interface controller that reads out a current identification code and current address information of the current identification code. A data comparator compares a previous identification code stored in a memory provided in the timing controller with the current identification code. If the current identification code is different from the previous identification code, the interface controller reads out current parameter data corresponding to the current identification code from the memory and a data processor processes image data by using the current parameter data. The timing controller recognizes the update state of the parameter data stored in the memory and processes the image data by using the updated parameter data.

    摘要: In a display apparatus, one frame includes a first sub-frame in which a previous image is held and a second sub-frame in which a present image is displayed. A plurality of sensors recognizes an object disposed on a display panel and sequentially outputs sensing signals in response to scan signals. Sensing signals are divided into a first sensing signal read out during a first sub-frame and a second sensing signal read out during a second sub-frame, and a control circuit generates a noise free signal using the first and second sensing signals. Thus, a coordinate value indicating the position of the object may be generated based on the noise free signal, thereby preventing mis-operation or malfunction caused by the noise.

    摘要: A liquid crystal display and a driving method therefor comprises a plurality of pixels arranged in a matrix; data lines and gate lines connected to the pixels; a signal controller processing first image data and a plurality of control signals from an external device and transmitting the processed first image data and control signals; and a data driver connected to the signal controller, wherein the signal controller divides the first image data into and sequentially processes a plurality of sets respectively including the first image data for at least two pixel rows, while delaying the remaining image data excluding the last image data among the first image data of each of the sets, and the data driver applies a charge sharing voltages as impulse voltages to the predetermined number of pixel rows during the delayed time, thereby displaying impulse images. In this way, since impulse images are displayed only by delaying image data within the same time and separate black image data are not transmitted, the data transmission frequency is not increased.

    摘要: An artificial marble using chips made of a low specific gravity material via a lamination or crunch technique to realize a natural stone-like texture, and a process for preparing the artificial marble are disclosed. In one example, a high specific gravity layer containing a high specific gravity inorganic filler is laminated on a low specific gravity layer made of a low specific gravity material to form a flat board, and then, the flat board is crushed to produce chips. In another example, low specific gravity regions made of a low specific gravity material is coated with a high specific gravity slurry containing a high specific gravity inorganic filler, to produce crunch chips. Thereby, a low specific gravity material, which could not be used conventionally, is applicable to the artificial marble, so as to achieve an outer appearance remarkably similar to a texture of natural marbles.
