摘要: A display apparatus that can conserve power without compromising general display quality is presented. In a display system including a main control apparatus and a display apparatus, the main control apparatus generates an image control signal having an image data, and a main clock signal that changes from a first frequency to a second frequency in response to a change in image mode from a first image mode to a second image mode. The change from the first frequency to the second frequency includes changing through at least one intermediate frequency stage between the first frequency and the second frequency. By maintaining the change of frequency shift small (i.e., less than a predetermined maximum change), operation in emergency mode is avoided even when the frequency shift is sudden. The display apparatus receives the image control signal and the main clock signal to display an image.

摘要: Disclosed is an LCD apparatus having improved display characteristics. A clock generator applies first and second clock signals to a gate driver so as to control a pulse width of a gate driving signal. A discharging transistor connected to first ends of gate lines discharges a present stage before operating a next stage. The gate lines include a first gate driver and a second gate driver for operating the gate lines while the first gate driver is operated in an abnormal state. Accordingly, the LCD apparatus may be operated in high-speed and prevent the gate driving signal from being delayed.

The LCD further includes a plurality of gate lines transmitting a plurality of gate signals, a plurality of data lines transmitting the gray voltages, and a plurality of pixels. Each pixel has a switching element connected to one of the gate lines and one of the data lines and transmitting the gray voltages to the pixels under the control of the gate signal. The LCD includes a gate driver supplying the gate signals to the gate lines and a data driver selecting the gray voltages based on gray data from an external source to supply to the pixels via the data lines.

摘要: Disclosed is a liquid crystal display device in which printed circuit board (PCB) modules are suitably arranged to form a large screen with high resolution. The liquid crystal display device includes first and second main PCBs for driving a dual bank type liquid crystal panel, the first main PCB having a timing controller for processing external odd input signals to generate driving signals, and sending part of the driving signals to a corresponding source driver PCB, so as to generate video signals to be supplied to the odd pixels of the liquid crystal panel; and the second main PCB having a timing controller for processing external even input signals to generate driving signals, and sending part of the driving signals to a corresponding source driver PCB, so as to generate video signals to be supplied to the even pixels of the liquid crystal panel. According to the present invention, two source driver PCBs are used to supply video data to the upper part and the lower part of the liquid crystal panel, respectively, and thereby to reduce signal delay and distortion in driving the dual bank type liquid crystal display device for a large screen with high resolution, thus solving the problems of coupling between signals more deviating from the tolerance range with an increased frequency, noise, and EMI.

摘要: A gate driver includes multiple stages. Each stage has a circuit portion and a wiring portion. The wiring portion delivers first and second clock signals to the circuit portion. Further, the wiring portion includes first and second clock wirings receiving the first and second clock signal, respectively, first connecting wirings electrically connecting the first clock wiring with a first every other stage, and second connecting wirings electrically connecting the second clock wiring with the odd-numbered stages. Further, the wiring portion includes third connecting wirings electrically connecting the first connecting wiring with a second every other stage and fourth connecting wirings electrically connecting the second connecting wiring with the even-numbered stages. This configuration may prevent the gate driver from operating erroneously and reduce power consumed by the gate driver.
