摘要： A liquid crystal display (LCD) panel and driving circuit having a high response speed is provided. The LC panel at least includes a first group of gate lines, a second group of gate lines, and a first group of source lines, in which gate pulse signals can be fed to the LCD panel through the two groups of gate lines. Preferably, the LC panel further includes a second group of source lines, in which one of the two groups of source lines can be fed with the image data, and the other one is fed with a black image data. Accordingly, the LCD panel can only use the twisted nematic LC or the vertical alignment LC (VA-LC), without need of optically compensated birefringent LC (OCB-LC). Thus, the problems of a fast response speed LC panel using an OCB-LC can be avoided.

摘要： A voltage level shifter is provided. The shifter includes an AND gate for generating a synchronizing signal according to a periodic signal and a primitive input signal. The synchronizing signal and a first periodic control signal that are in phase with the periodic control signal are inputted to a transistor device. The transistor device is constructed with an inverter. The voltage level shifter further includes a buffer for generating an output signal and a capacitor for storing a signal. The present invention also provides a switching circuit for preventing the turning on of both PMOS transistor and NMOS transistor simultaneously during a switching status. The present invention can also solve the issue caused by the ratio of the channel width to the channel length, thus the uncertainty of the manufacturing process will not affect the circuit. Therefore, the power consumption, the chip area and the cost are reduced.

摘要： An addressable video camera has an ability to be assigned an address, that allows a security monitoring system utilizing a plurality of such addressable video cameras to be connected to the security guard room via a single cable. The addressable video camera includes the following: a video imaging device for generating a video signal; an amplifier for amplifying the output video signal; a switch connected between the amplifier and the input/output port of the addressable video camera; an address setting unit for presetting an address value to the addressable video camera; a sync signal detector which is capable of generating a demodulation enable signal in response to the received video control signal; a demodulator for demodulating the address signal in the video control signal; and a microprocessor capable of comparing the demodulated address data with the preset address value. If these match, the switch is turned to the conducting state and the video-imaging device is switched to active operation. It then outputs the video signal. Since the signal transmission between the central control unit and the plurality of addressable video cameras can be carried out over one single cable, the arrangement and handling of the security monitoring system is considerably simplified.

摘要： An image register for a graphics display includes a pair of static random access memory (SRAM) devices for respectively storing image data associated with even numbered and odd numbered pixels, which correspond to even numbered and odd numbered addresses. The register includes a counter presettable to an initial value corresponding to a starting address of the stored image data. When the counter outputs an even address (an even state), the even SRAM is enabled for a write operation if an input layer code has a higher priority than the priority of the layer code for the image data stored in the even SRAM, although the odd SRAM is always enabled for a read operation in the even state. The read and write operations occur simultaneously. During the read operation on the odd SRAM, the layer code portion of the image data retrieved therefrom is latched in an associated buffer, whose output is fed to an associated comparator. When the counter is incremented during the next clock cycle, the counter outputs an odd address (an odd state), wherein the odd SRAM is enabled for a write operation if an input layer code has a higher priority than the priority of the retrieved layer code buffered from the prior cycle, although the even SRAM is always enabled for a read operation in the odd state. Both operations occur simultaneously. In both the even and odd states, if the priority of the input layer code is not higher than the priority of the layer code associated with the current image data, the original image data is retained in the even and odd SEAMs, respectively.
