Abstract:
PURPOSE: A liquid crystal display apparatus, a liquid crystal driving apparatus, and driving method of liquid crystal display apparatus are provided to efficiently remove an after image by reducing stress to a liquid crystal. CONSTITUTION: A panel portion comprises at least one pixel group. The pixel group is composed of a plurality of pixels. A controller(200) inserts data into a part of pixels. The controller inserts gray data into the pixels in predetermined order pattern.

PURPOSE: A data communication method of a wireless device and a system using the same are provided to secure reliability of the system by preventing the hacking of the key, the encryption information, and the decoding information. CONSTITUTION: A key generator(202) generates a character key including at least one encryption key and the encryption information. A controller(203) stores a character key in a memory(205). A display unit(204) displays the generated character key. The character key displayed in the display unit is inputted through an input unit(104). A controller(102) decodes the character key. The controller encrypts the data using at least one encryption key and the encryption information. A wireless transmitter(103) transmits the encrypted data to the display unit. A wireless receiver(201) receives the encrypted data. The controller decodes the encrypted data. The display unit displays the image including the transmitted encrypted data.
Abstract:
PURPOSE: A frame rate converting device and method are provided to reduce the capacity of a line memory by sharing the line memory for storing video data required for motion estimation and motion compensation. CONSTITUTION: A frame rate converting device obtains a motion vector with respect to the second frame based on the first frame and forms the third frame interpolated between the first and second frames based on the motion vector to vary a frame rate. The frame rate converting device includes a motion estimator(570) for calculating the motion vector with respect to the second frame on the basis of the first frame, a motion compensator(580) for constructing video data for the third frame based on the first frame and the motion vector, a selector(530) for alternately selecting the motion estimator and the motion compensator, and a line memory(540) for selectively storing video data constructing the first and second frames and applying the video data to one of the motion estimator and the motion compensator in response to selection of the selector.
