Abstract:
A method for tracing at least one domain name is disclosed. In the method, several DNS resource records of candidate domain names are queried from at least one DNS name server. The candidate domain names are domain names that need to be traced. Internet Protocol (IP) addresses associated with the candidate domain names are retrieved from the DNS resource records of the candidate domain names. At least one external resource server is connected to retrieve corresponding registration information of the respective IP addresses of the candidate domain names. A tracing weight of each of the candidate domain names is calculated according to the DNS resource records, the IP addresses and the corresponding registration information of the candidate domain names. The candidate domain names are traced according to their respective tracing weights. A system for tracing at least one domain name is also disclosed.

Abstract:
An overdrive accuracy adjustment device and method for use in liquid crystal display panel is presented. According to a current grayscale value of a pixel in an awaiting to be displayed image and a previous grayscale value of the corresponding pixel in an already-displayed image, the corresponding overdrive grayscale value is found from the look-up table. In order to more efficiently use the limited storage capacity of the look-up table as well as improving the accuracy of the overdrive, in accordance to the physical characteristics of the liquid crystal display panel in particular (in particular to the grayscale values which often required the overdrive), the gap size between the current grayscale values and/or the previous grayscale values with each other should be adjusted in the look-up table, without having to increase the quantity of the overdrive grayscale values stored in the look-up table.
Abstract:
The present invention discloses a method for driving a liquid crystal display device for enhancing a picture quality. More specifically, a method for driving liquid crystal display in a multi-frame polarity inversion manner is disclosed. Based on standard liquid crystal display structure, hardware and specification, the method improves frame rate by increasing input rate of grayscale level with a better brightness performance and fewer loss of grayscale. The method comprises the following steps of: setting two or more voltage-controls during frame period of liquid crystal display panel to increase frame rate; setting a first grayscale level and a first voltage corresponding to the first grayscale level to represent brightness on liquid crystal display panel during a first voltage-control; and setting a second grayscale level and a second voltage corresponding to the second grayscale level to represent brightness on liquid crystal display panel during a second voltage-control which is just behind and in the same polarity as the first voltage-control.

The multi-functional comparing unit is used for comparing a recovered OD value of the recovering module, a grayscale of the color signal source, and a comparison result of the comparing unit are compared and then outputs a result of either the grayscale of the current frame or the recovered OD value. By this way, the color display system can respond to display grayscales of colors fast and accurately. The color display system is suitable for a liquid crystal display (LCD), a plasma display panel (PDP), a thin film transistor (TFT), an organic electro luminescence display (OLED), and a polymer light emitting diode (PLED).

The method increases the output frame rate to p/q (p, q are both natural numbers and p>q) times of the input frame rate. In a period of time equal to the least common multiple of the input and output frame times, q input frames are output and (p−q) transient frames are generated and inserted at appropriate places before or after the q input frames in the output frame sequence so as to enhance the dynamic display effect of the display device.

Abstract:
The present invention relates a time-sharing multiplexing driving method and framework for image signals. By means of a plurality of wiring paths, the turned-on orders of the signal switches of the pixel units in a liquid crystal panel (LCD) are sequentially controlled so that the pixel units of two adjacent phases in the panel can have the same turned-on order. This not only can avoid the situation where the switch control signal serial connecting path in the panel is so long that the control signal of the end switch will be seriously distorted for the excessively great load, but also make the variation amounts of the adjacent pixel data voltages the same. Therefore, the objective of the invention can be achieved. Namely, no joint space is generated during the image signal time-sharing multiplexing driving.
