Title: Device and method to drive liquid crystal display device
Inventor: NARIAMA SEIJIROU
IPC: G02F1/133
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To eliminate the unevenness in the luminance caused by the variations of the display pattern in a simple matrix liquid crystal display device and to improve the display quality by minimizing the loss of the effective voltages applied to the liquid crystal cells. SOLUTION: A segment side driving circuit 2, which drives the segment electrodes of a liquid crystal panel 1, compares the display data of one scanning period prior to the present and the present display data. Only if these data are matched to each other, the compensation for the intermediate level of the output voltage is conducted based on the compensation clock signal. Since a variation is added when there is no change in the display patterns, the effect of waveform corruption is equalized regardless of the display patterns and the unevenness of the luminance is resolved. If there exist changes in the display data, the loss of the effective voltage value due to the compensation is eliminated and the increase in the current consumption is suppressed.  Furthermore, two compensation periods are provided, the luminance unevenness is resolved and the spikes of the common side during the changes of the display data are reduced.

Abstract: PURPOSE:To perform wire routing in the upper space of a wiring circuit board so as to increase the number of wires wirable to one circuit board by providing a jig having a wire fixing section covering a partial or all surface of the circuit board to the circuit board at the point of time when no margin is left in its grating space because of an increased number of wired wires. CONSTITUTION:When wiring works are performed on the surface of this wiring circuit board, an MPU manages the coordinates of positions of main routes 5 for wiring wires 4 and fixing sections of the wires where the wires are fixed to the circuit board as working information and discriminates the limit of the number of wires wired on the surface of the circuit board. From the stage where the MPU discriminates that the number of wired wires on the surface of the circuit board 1 reaches the limit, most of the remaining wires 4 to be wired are kept nearly vertically on the circuit board 1 after only the starting point sides of the wires 4 are connected to bonding pads 3. Then a wire holding jig 6 is fitted to the circuit board 1 so that the pattern of the wire fixing section 62 on the jig can match the main route on the circuit board 1. After fitting the jig, 6 wire routing is performed to sections nearly above the bonding pads 3 by fixing the wires after changing leading-out directions of the wires in a state where the wires 4 are put around the fixing section 62 as required.

IPC: A61F9/02
Filed: 1988-11-25
Abstract: PURPOSE:To remove the blur of a lens generated when goggles are used in a cold district by extracting the heat of a breath to heat the lens and evaporating the water droplets on the lens. CONSTITUTION:A cover 10 is removed and a film 8 is applied to the blurred lenses 11 of goggles and a breath blowing-in port 1 is drawn out from the leading end part 9 of an exhaust pipe 4 to be taken in a mouth and a breath is blown in said port 1. The breath enters a breath sump part 3 through a breath injection pipe 2 to be discharged from the exhaust pipe 4. At this time, the film 8 is pushed up by the breath of the breath sump to be closely adhered to the lenses 11 and, further, the heat of the breath is extracted by the film 8 to be transmitted to the lenses 11. By this method, water droplets adhered to the lenses are evaporated to remove the blur. Further, since the breath injection pipe 2, the breath sump 3 and the exhaust pipe 4 are formed using a heat insulating material, the heat of the breath does not escape too much and, since the both surfaces of them are covered with a waterproof material 6 such as a vinyl material, the heat insulating material can be protected from snow or the moisture of the breath.
