A liquid crystal display according to the present invention can prevent interference fringe on a display panel due to a switching noise of a DC/DC converter, therefore a high-quality image can be displayed. Either of input signals for a timing control circuit is also supplied to a PLL circuit and the DC/DC converter is controlled by an output signal of the PLL circuit, thereby enables to synchronize a switching frequency of the DC/DC converter and control signal.

Liquid crystal display

A liquid crystal display device is provided with a image data inputting means for inputting image data and a image data memory for storing image data comprising a number of bits which is fewer than the number of bits in the image data input to the image data inputting means, on the basis of this image data. In addition, a liquid crystal display device is provided with corrected data generating means for generating corrected data by correcting the current image data input to the image data inputting means, on the basis of previous image data stored in the image data memory. Consequently, the liquid crystal display device enables the capacity of image data memory for storing previous image data to be reduced, thereby yielding a merit in that cost savings can be achieved.

Liquid crystal display device and drive circuit device for

The present invention is directed to a liquid crystal display apparatus including: a timing circuit for operating a shift register within a timing circuit during a vertical blanking period such that a common signal that has been alternated at a cycle of a Single Horizontal period is applied on counter electrodes during the vertical blanking period and such that a storage electrode signal is applied on storage electrodes having a frequency, phase and amplitude identical to those of the common signal.

Liquid crystal display apparatus and driving method therefor

The present invention is directed to a display apparatus including a correcting means for producing a current corrected data signal by using a current image data signal and a previous corrected data signal; a storage means for storing said current corrected data signal within a predetermined frame period, outputting said current corrected data signal as the previous corrected data signal in such a manner as to be delayed at most said predetermined frame period; and a display means driven by a driving signal corresponding to said current corrected data signal.
