Abstract
From a matrix electrode (2) provided for a liquid crystal display, a signal indicative of an amount of electric charges between a pair of electrodes that constitutes the matrix electrode (2) is inputted to an input unit (41). A comparison unit (42) compares that signal with a prestored signal indicative of an amount of electric charges between the pair of electrodes in the matrix electrode (2) measured when displaying has been performed normally by the liquid crystal display. A determination unit (43) determines whether a display on the liquid crystal display is normal or abnormal, using a comparison result by the comparison unit (42).
Claims9
A display confirming device, comprising:
- an input unit to which, from a matrix electrode provided for a liquid crystal display, a signal indicative of an amount of electric charges between a pair of electrodes that constitutes the matrix electrode, is inputted;
- a comparator to compare the signal inputted to the input unit, with a prestored signal indicative of an amount of electric charges between the pair of electrodes measured when displaying has been performed normally by the liquid crystal display;
- and
- a determiner to determine whether a display on the liquid crystal display is normal or abnormal, using a comparison result by the comparator.
A display confirming method comprising:
- inputting, from a matrix electrode provided for a liquid crystal display, a signal indicative of an amount of electric charges between a pair of electrodes that constitutes the matrix electrode, to an input unit;
- comparing, by a comparator, the signal inputted by the input step, with a prestored signal indicative of an amount of electric charges between the pair of electrodes measured when displaying has been performed normally by the liquid crystal display;
- and
- determining, by a determiner, whether a display on the liquid crystal display is normal or abnormal, using a comparison result by the comparison step.
