Abstract:
A display device for displaying an image on a display panel having a plurality of electrode rows and a plurality of electrode columns arranged in transverse relation to said electrode rows, by applying various drive pulses to each of said electrode rows and said electrode columns,said display device comprising: a selector for selecting one of a plurality of input video signals in response to an input video selecting signal to capture a selected input video signal as a selected video signal, image processing parameter memories for storing image processing parameters corresponding to each of said input video signals, parameter selecting means for alternatively selecting one of said image processing parameters stored in said image processing parameter memories in response to said input video selecting signal, a parameter register for storing, by overwriting, said image processing parameters selected by said parameter selecting means in response to a switching between said input video selecting signals, image signal processing means for obtaining drive data by performing an image signal processing on said selected video signal in accordance with said image processing parameters stored in said parameter register, display panel drive means for generating each of said drive pulses to be applied to each of said electrode rows and said electrode columns in accordance with said drive data, and means for stopping said display panel drive means from generating said drive pulses for a predetermined period in response to the switching between said input video selecting signals.
