Abstract:
A liquid crystal display device for displaying an image expressed by display data comprising plural pieces of pixel data, which are sequentially inputted, comprising:a liquid crystal panel, including pixel parts having liquid crystals arranged in M rows and N columns;a liquid crystal driver, including:N storage element groups, each of which is provided corresponding to each of said N columns respectively, for capturing and storing the pieces of pixel data sequentially, inputted and then simultaneously outputting the pieces of pixel data stored therein when all pieces of pixel data for a complete row have been captured and stored,a voltage generator for changing each of the pieces of pixel data simultaneously outputted from said N storage element groups to a liquid crystal apply voltage, andN drain signal lines, each of which is provided corresponding to each of said N storage element groups respectively, each of said drain signal lines transferring the liquid crystal apply voltage according to a piece of pixel data outputted from a storage element group corresponding thereto to pixel parts of a column corresponding to the storage element group; anda scanning driver for sequentially selecting any one of said M rows in response to the simultaneously outputted pieces of pixel data, applying a select voltage to pixel parts of the selected row, and applying a de-select voltage to pixel parts of the other rows not selected,wherein the number of pieces Y of pixel data of the display data in the selected row is smaller than N, andwherein at least two of said storage element groups simultaneously capture and store a same piece of pixel data, whereby Y pieces of pixel data are changed to N pieces of pixel data, and then are simultaneously outputted from said N storage element groups.
