摘要:
A digital data line driver includes a data input circuit for fetching data in response to an external clock, a reference voltage supply circuit having reference voltages corresponding to a plurality of gray-scale levels, a selector circuit for selecting a specified reference voltage representing the data from among those of the reference power supply circuit, and an output circuit for outputting the reference voltage selected by the selector circuit as display data onto data lines. The data input circuit and output circuit have a data-crossing function for switching data between adjoining channels of the data lines according to an external data switching control signal. Owing to this configuration, deterioration of liquid crystal can be prevented and a better display can be attained with suppressed flickers. At the same time, the picture-frame space can be reduced.

A drive circuit for a display device including a display panel for displaying an image line by line has a data register. The data register is used to store optional data in response to a control signal, to overwrite the stored optional data with display data, and to prepare display data for a given line of the display panel. The data prepared in the data register is transferred to the display panel to display the given line of the display panel. The drive circuit is capable of supplementing display data if the display data is improper for the display, thereby securing the quality of the displayed images.

A common electrode driving circuit is provided on a TFT substrate as a first substrate. Striped common electrodes are formed along the layout of pixels, such as data lines (or scanning lines), on a common substrate as a second substrate. The common electrode driving circuit inverts a common electrode voltage that is applied to a common electrode of an odd-number order, relative to a common electrode voltage that is applied to a common electrode of an even-number order. The common electrode driving circuit inverts these common electrode voltages to match the polarity inversion period at the same time. Based on this, a common inversion driving system is realized, and flicker is reduced according to a lengthwise line (or crosswise line) inversion driving system.

A reflective electrode, a transparent electrode, a TFT connected to the reflective electrode and a TFT connected to the transparent electrode are formed in each picture element. A first data signal is written into the reflective electrode via the TFT, a second data signal is written into the transparent electrode via the TFT. In this way, the individual data signals are respectively written into the reflective electrode and the transparent electrode, and thereby excellent display quality can be obtained either when used as a transmissive liquid crystal display device or when used as a reflective liquid crystal display device.
