IMAGE DISPLAY DEVICE

摘要

An image display device includes a light source that emits a light beam, a screen, a scanning section that scans the screen with the light beam, an optical system, a drive section, and a screen drive circuit. The optical system generates a virtual image by using the light beam that has passed through the screen. The drive section moves the screen at least in parallel to a travel direction of the light beam. The screen drive circuit contains a drive signal table that stores an information group for use in generating a drive signal tailored to stop the screen at different stop locations over different stop periods. The screen drive circuit selects first information in the drive signal table which is associated with displaying of an image and supplies the drive section with a first drive signal generated from the first information.

主权项

1. An image display device comprising:
a light source that emits a light beam; a screen that is scanned with the light beam to create an image; a scanning section that scans the screen with the light beam emitted from the light source; an optical system that generates a virtual image by using the light beam that passes through the screen; a drive section that moves the screen at least in parallel to a travel direction of the light beam; and a screen drive circuit that drives the drive section, wherein the screen drive circuit contains a drive signal table that stores an information group for use in generating a drive signal that causes the screen to reciprocate over a predetermined period, the drive signal table is configured such that the information group is tailored to stop the screen at different stop locations over different stop periods, the stop locations being confined within a range of the reciprocation of the screen, and the screen drive circuit selects first information in the drive signal table which is associated with displaying of the image and supplies the drive section with a first drive signal generated from the first information.
