Patent ID: 8068076

Claim:
A display apparatus, comprising: a modulation element in which a liquid crystal layer is provided between a first electrode and a second electrode; and a controller configured to perform a first control mode for applying a voltage between the first and second electrodes such that, within each of plural consecutive frames of an image signal, a positive liquid crystal applied voltage is first used to write one field image, and then a negative liquid crystal applied voltage is used to write next one field image, and over drive is performed when writing the field image with the positive liquid crystal applied voltage, wherein the controller is configured to further perform a second control mode for applying a voltage between the first and second electrodes, wherein, within each of plural consecutive frames of the image signal, a negative liquid crystal applied voltage is first used to write one field image, and then a positive liquid crystal applied voltage is used to write next one field image, and overdrive is performed when writing the field image with the negative liquid crystal applied voltage, and wherein the controller controls the display apparatus to display red, green and blue image and switches between the first and second control modes during a period in which only a blue image is displayed.
