LIGHT GUIDE PLATE PATTERN WET ETCHING APPARATUS CAPABLE OF PRECISELY PROCESSING AN INTAGLIO PATTERN ON A LIGHT GUIDE PLATE THROUGH AN ETCHING PROCESS

摘要

PURPOSE: A light guide plate pattern wet etching apparatus is provided to perform a first etching process of a light guide plate by an etching heater part, thereby precisely arranging an etching pattern by performing a second etching process using an etching liquid.;CONSTITUTION: A light guide plate(121) is loaded and unloaded on the upper surface of a support stand(110). A light guide plate supporting frame(120) supports the light guide plate and a mask(123). A magnetic attaching part(130) closely attaches the mask in the light guide plate using magnetic force. An etching heater part(140) arranges a pattern by applying heat on the surface of the light guide plate. A heater power source(160) supplies power to a heater(143) of the etching heater part.;COPYRIGHT KIPO 2012
