Abstract: A rotation-type single-pull retract mechanism includes a housing with a lower housing and an upper cover, a rotation mold, a plate-shaped spring, and a wire material. The lower housing has a positioning shaft and at least one blocking element movably mounted on the lower housing. Two wire-outlet holes are formed on the sides of the housing. The rotation mold has a wire winding shaft and a ratchet-wheel-shaped boss with at least two positioning teeth that corresponds to the blocking element. The rotation mold has a wire-through hole, a wire winding annular wall with the plate-shaped spring placed within, and a first through-hole engaged with the positioning shaft. Therein, an inner root portion of the plate-shaped spring is fixedly connected with the positioning shaft. Thereby, the wire material may be reeled on the wire winding annular wall, so that two ends of the wire material passes through the two wire-outlet holes.

Abstract: A driving method to improve response time of twisted nematic (TN) and super twisted nematic (STN) passive matrix LCDs without increasing graphic memory (GRAM) adopts an over-driving operation principle to convert data of three primary colors to YCbCr data and over-driving YCbCr data. Then compressing, sampling and combining are performed through a video compression standard to further reduce a portion of storage bits of the YCbCr data and over-driving YCbCr data. Through an output frequency doubling circuit an over-driving compensation potential higher or lower than the original output potential is flexibly given N times according to the over-driving Y?Cb?Cr? data within the update time period of each data bus. Thereby the response time of the LCDs improves without increasing the GRAM and dynamic picture blurring phenomenon also improves.

Abstract: The present invention discloses an over-driving compensation method to shorten the response time of a passive matrix liquid crystal display, wherein N frames are arranged into a super-frame; the data of the current frame is compared with the data of the previous frame; once the data of the current frame is different from the data of the previous frame, the pictures are determined to be moving pictures; and when the pictures are determined to be moving pictures, an over-driving voltage, which is higher/lower than the traditional high-level driving voltage/the traditional low-level driving voltage, is assigned to each of from the ith frame to the jth frame of each super-frame. Thereby, the liquid crystal can faster approach or reach the specified target brightness. So the blurring of moving pictures will be greatly reduced.

Abstract: A shared pixels rendering display includes the procedures of taking samples of sub-pixels (r, g, b) of original pixels that mate the pixel layout (R, G, B) of a color filter; determining content variations of neighboring pixels after sampling, and redistributing after a weighted ratio has been applied to the neighboring pixels of the same color; and a driving IC distributing pixel signals after sampling and weighted ratio redistributing to a mating color filter for displaying. By means of the sampling and weighted ratio redistribution, signal channels required for the display area may be reduced. Hence by using human eye vision error, unnecessary image pixels may be reduced, and the number of required driving IC decreases.
