Title: Driving system for ferroelectric liquid crystal element
Inventor: OKADA SHINJIRO
IPC: G09G3/36
Filed: 1985-07-12
Abstract: PURPOSE:To permit the high-speed driving of a ferroelectric liquid crystal by detecting the write signal to be applied to display signal line groups subjected to sequential linear scanning. CONSTITUTION:Means for detecting the writing signals to be applied to the line groups of the display signals I1-I5 to be subjected to sequential linear scanning are provided to detect the writing signals to be applied to the line groups of the display signals I1-I5 and to prevent the continuous impression of the reverse bias to be applied to picture elements by impressing auxiliary signals to the detected lines or all the lines when the writing signals to put the picture elements into the same display state are continuously impressed for the specified period. The removal of the crosstalk at non-selection points and the high-speed driving of a ferroelectric liquid crystal are thereby made possible. The auxiliary signals are impressed from both or either of the lines for the scanning signals S1-S12 or the lines for the display signals I1-I5 to the picture elements.

Filed: 1982-08-31
Abstract: PURPOSE:To reduce the frequency of erroneous data input, by giving a notice to an operator by the operation of the output part of a data input device to indicate the kind of the error when a miss is generated at the time of data input, and inputting the data again. CONSTITUTION:When data are inputted from a data input device 10 to a data collecting computer 50, the data are parity-checked at first and then written in a prescribed address of a memory once. Subsequently, a signal indicating that the error of the input data is an error except the upper and lower limit, an error except a normal value range or an error within the normal value range is fed back to the device 10. The feedback signal actuates a lamp 18 incorporating an item key, numerical display part 20, display lamp 22 for an out-of-range data error, and a sound generator 24 to give a notice to the operator. Consequently, the data are inputted again and the contents stored in the computer 50 is rewritten to correct the miss.
