Abstract: A liquid crystal display (LCD) device includes a display control circuit to receive data of each frame of an external image signal and a liquid crystal panel. When the data of an n+1 frame currently received is the same as that of an n frame previously received, the display control circuit outputs first gray scale voltages corresponding to the data of the n+1 frame to drive the liquid crystal panel. When the data of the n+1 frame is different from that of the n frame, the display control circuit generates data of at least one inserted frame between the data of the n and the n+1 frames, and outputs second gray scale voltages respectively corresponding to the data of the at least one inserted frame and the n+1 frame to drive the liquid crystal panel to display first an image of the least one inserted frame and then that of the n+1 frame. An absolute value of a second gray scale voltage exceeds that of a first gray scale voltage for a same gray scale.

Abstract: An LCD includes a liquid crystal panel having a plurality of pixel units each including a liquid crystal capacitor, a scanning circuit for providing scanning signals to the pixel units, a data circuit for providing gray-scale voltage signals to the pixel units; and a timing controller for receiving at least one timing signal and providing a timing control signal to control a driving timing of the scanning circuit and the data circuit according to at least one timing signal. The timing controller outputs a reset control signal to the scanning circuit upon detecting that the liquid crystal display enters a power-off state based on the at least one timing signal. The reset control signal directs the scanning signal to activate all the pixel units to discharge liquid crystal capacitors. A method for driving a liquid crystal display is also provided.

Abstract: A liquid crystal display (LCD) device includes data lines, pixel units, a first repair line intersecting and disposed on a first side of the data line, a second repair line intersecting and disposed on a second side of the data line, a delay circuit connected between the first repair line and the second repair line, and a control circuit. The control circuit controls a delay time of the delay circuit according to a position of each pixel unit corresponding to a broken data line.

Abstract: An onscreen display (OSD) system for a display device includes an OSD module including a microprocessor and a memory. The memory stores instructions about adjustment of a display characteristic and the microprocessor reads the instructions and generates an OSD menu including the instructions. An operation method for the system is also provided.
