摘要： PROBLEM TO BE SOLVED: To provide drive circuits of a display device, such as a liquid-crystal display device in which the drive circuits are integrated, which are able to solve the problem that serious surface defects may occur as the result of dust trapped during manufacturing processes. SOLUTION: At each step of lines of shift registers in a video signal line drive circuit or a scanning line drive circuit, a first, second, and third shift registers 11-13 operate in parallel, and a majority decision is made on their outputs by majority circuits 14-17. Therefore, even if a defect occurs in one of the shift registers and its operation stopped, a normal shift pulse is transmitted to the next stage to allow the shift register lines to operate normally.

摘要： PROBLEM TO BE SOLVED: To easily display the non-display data in a non-display area by performing write-in of the non-display data for all one horizontal pixels with a reset signal. SOLUTION: When a pixel display is performed based on a video signal, a scanning line drive circuit 293 outputs successively a gate ON voltage to scanning lines Y1 -Yn . A drain is conducted with a source in each TFT 121 by receiving this gate ON voltage, and then, the video signal from a video signal line Xo (i=1-n) is led to each pixel electrode 151 through the answering TFT 121. Thus, a potential difference between a counter electrode and the pixel electrode 151 is applied to a liquid crystal layer 351, and a display is performed based on this potential difference, and a charge is held between the pixel electrode 151 and a hold capacity line 211 also. Then, because this charge is held, during respective field periods, display images are kept. At this time, only by changing the reset signal, the non-display data are written in the signal line in the non-display area in a horizontal retrace period.

摘要： PURPOSE: To achieve the welding excellent in the quality for the narrow gap with small deposition, and to unnecessitate the manufacture of a welding torch of special structure. CONSTITUTION: In the TIG welding method in which a tungsten electrode 3 is inserted in a narrow gap 2a of works 1a, 1a, and the shield gas flows to achieve the arc welding, the double shield gas of the inner side shield gas 13 flowing from the periphery of the tungsten electrode 3 to its tip part and the outer side shield gas 14 having the stream toward the narrow gap 2a and the stream toward the outside is used. The tungsten electrode 3 can be projected from an energizing part 15 and an outer shield 12 by the length of 20 to 100mm. The inner side shield gas 13 prevents consumption of the long-projected tungsten electrode 3, and the outer side shield gas 14 prevents oxidation of the molten pool and also prevents inclusion of oxygen in the air. The sound welding is achieved thereby.

摘要： PURPOSE:To realize a stable and high-quality image display while resolving the problem of a flickering display screen and to provide a simple-construction and low-manufacturing cost liquid crystal display device. CONSTITUTION:The final output stage of an output buffer to be used for a scanning line driving circuit adopts constant current source load type inverters 211 and 212, and the waveform of a scanning pulse VY at its rise time is made sharp and that of a scanning pulse VY at its fall time is made gentle. Accordingly, since the scanning pulse gently and gradually falling down can supply electric charge to a floating capacity CGS, within the switching element of the liquid crystal display element during the gentle falling down of voltage, the part of the electric charge to be applied to the liquid crystal can be prevented from being deprived by the floating capacity CGS. Thus, the level shifting of the liquid crystal application voltage generated can be suppressed.
