Abstract
It is an object to provide an array-type light modulating device and a method of operating a flat display unit with which even electromechanical light modulating devices, which require a long time to restore the original positions, are able to significantly shorten substantial response time without deterioration in the image quality and loss occurring owning to the restoring time.An array-type light modulating device incorporating electromechanical light modulating devices which are arranged to perform light modulation by using an operation for displacing flexible portions by dint of electrostatic force and an elastic restoring operation of the flexible portions and which are disposed into a two-dimensional matrix configuration, wherein a resetting operation of the light modulating devices is performed simultaneously with a writing operation period for scanning lines except for the present scanning lines so that the resetting operation is completed before the writing operation for the light modulating devices to continuous perform the writing operation for each scanning line.
