Abstract

A pattern forming apparatus for a light guide panel is provided. The apparatus includes a pattern design system, a control system, a header moving unit including an XY moving unit and a header unit, one or more laser systems, and two or more optical units. The pattern design system has an input of data on a pattern. The control system connects with the pattern design system and transmits a position signal. The XY moving unit mechanically moves up / down and left / right in response to the position signal. The header unit is coupled with the XY moving unit and reflects a scanned laser beam. The laser systems output laser beams by a pulse signal. The optical units each reflect and collect the laser beams.

Description

technical field [0001] The present invention relates to an image forming device used for the backlight of a liquid crystal display element, a keyboard, a telephone, a surface light source for illumination, etc., and specifically relates to an image forming device characterized by the following content, wherein the laser beam is separated Several concentrated laser beams are formed, and the laser head mover that can move up, down, left, and right is used to scan the laser beams to form a light guide image. Background technique [0002] Generally, a light guide panel is a plate-shaped body that provides a path for uniformly dispersing and diffusing light swept by a light source, and is suitable for light-receiving flat-panel display devices such as liquid crystal display elements or surface light source devices such as light boxes. [0003] The most widely used method in the surface light source device using the light guide plate is the method of setting cold cathode fluoresce...
