DISPLAY APPARATUS USING LASER

摘要

a divider for dividing an input synchronizing into a horizontal and vertical synchronizing signals; a first converter for converting a video signal to a digital video signal; a controller for controlling the scanning position and the division of picture region according to the picture size; several memories for storing an input composite video signal from the first converter by picture region; several second converters for converting the stored data into an analog signal, and generating red, green and blue analog signals; a scanner for scanning with the laser beams corresponding to the size of the red, green and blue signals generated from the second converters; and a scanning controller for controlling the path of the laser beams. The distance adjustment between the display device and the display surface can be adjusted to control an image size.
