A display apparatus includes (a) a display panel having a display picture area formed by scanning electrodes and data electrodes arranged in a matrix; (b) a driver including a first driver for driving the scanning electrodes and a second driver for driving the data electrodes; and (c) a controller for controlling the driver so as to repeat a partial rewriting scanning operation by applying a scanning selection signal to only a part of the scanning electrodes forming the display picture area. In addition, the apparatus operates in an interlace mode when normal field scanning is performed and in a non-interlace mode when partial scanning is being performed to change the position of the cursor. In addition, the apparatus includes a flag memory for setting one bit of data for each electrode.

In a method of driving a liquid crystal panel using one horizontal period (1H) as a reversal period, the liquid crystal panel using a TFT as a switching element for driving the panel in units of divided blocks and comprising the block division TFT's (B-TFT), a matrix circuit for driving each block in time division, and a TFT active matrix panel; each block of the B-TFT's is further divided into two half-blocks and a control signal shifted in phase between adjacent two half-blocks is applied to time-divisionally drive the liquid crystal panel at superposed timings. High intensity lines produced at the intersection of blocks due to the charge sharing effect are eliminated to thereby enable a high quality image to be produced.

A data processing apparatus includes an image information storage memory and a controller for controlling the image information storage memory. The storage memory stores first graphic event data in accordance with a demand for displaying from a pointing device at a certain cycle and stores graphic event data in accordance with a demand for displaying a scrolling in a window on a display panel. When display requests of the first graphic event data and the second graphic event data occur simultaneously, and when no change is caused in data relating to position from the pointing device, storage of the second graphic event data into the memory is allowed and storage of the first graphic event data is performed. The image information controlled by the controller is displayed on a display panel.
