Title:
SCREEN DEVICE OCCURRING MOIRE
Document Type and Number:
Japanese Patent JPS5493400
Kind Code:
A
Abstract:
An arrangement and structural cross section of grid lines in screens which present a moire pattern. The cross-sections of the screen lines are arranged so that light from behind the screen is not reflected on the front of the grid lines and the moire pattern, as seen by an observer at the front of the screens, better depicts the information pattern by avoiding distortion arising in prior art structures. Several embodiments of screen grid line cross-sections are proposed.
