Abstract: A method for driving a display apparatus is provided which apparatus includes a display section having pixels and switching elements respectively connected to the pixels, and also includes a data driver for driving the display section, and data lines connecting the switching elements to the data driver, the pixels being allowed to produce a display image by specific voltages applied thereto. The method includes the steps of: allowing the data driver to output a non-oscillating voltage signal to each of the data lines during a predetermined time period from the start of one output period; and allowing the data driver to output an oscillating voltage signal to each of the data lines from the end of the predetermined time period until the end of the output period, the oscillating voltage signal including at least one oscillating component.

Abstract: The column electrode driving circuit is suitable for driving a display apparatus which has a delta arrangement display unit. The video signals for two rows in the display unit are sampled simultaneously by two sample-hold circuits with sampling timings which differ mutually by one-half of the sampling period. The outputs of the two sample-hold circuits are alternatingly supplied to column electrodes of the display unit.

Abstract: There is provided a column electrode drive circuit applicable to a display-integrated type tablet. A hold circuit has a plurality D-flip-flops. To clock terminals of the flip-flops is input an output signal of an AND circuit which receives inputs of a hold signal and a clock signal. To data terminals of the flip-flops are input sampled display signals. With the above-mentioned arrangement, when the hold signal is at "H" level, the sampled display signals are sequentially output as display signals without modification based on the clock signal. When the hold signal is a pulse signal, the sampled display signals are simultaneously output and held as the display signals. By thus making a simultaneous output function and a sequential output function compatible, the column electrode drive circuit can be utilized as a column electrode drive circuit for the display-integrated type tablet device.
