Abstract:
1. A liquid crystal display device comprising: a liquid crystal display panel which has a plurality of pixels constituted of active elements and formed in a matrix; a plurality of drain drivers which apply driving voltages based on control signals including image data and pixel clock signals inputted from an external signal source to a plurality of pixels in a lateral direction of the matrix; a plurality of gate drivers which apply scanning voltages to a plurality of pixels in a longitudinal direction of the matrix; and a display control device having parallel-serial conversion means which performs a parallel-serial conversion of the image data based on the pixel clock signals and supplies the image data to the drain drivers, wherein the display control device comprises: provided that the number of the image data is set to N pieces, the number of display data inputted to the drain drivers of the liquid crystal display panel is set to M pieces, and N/M is set to satisfy the relationship of 1/a (a: integer), the N pieces of display data is converted into M pieces of display data (M≦N) based on clocks a×CL which is obtained by multiplying the frequency “a” times using a clock multiplying circuit and, thereafter, the M pieces of display data are inputted to the drain drivers at double edges consisting of rising of signal and falling of signal of the clocks CL.
