Abstract

The present invention relates to a glare shield frame for liquid crystal display (LCD) that is made with less material at largely reduced cost, and to a method of producing the frame. The frame is entirely or partially formed from multiple divided parts that could be assembled into an integral frame by mechanically connecting at two corresponding ends. Each connecting end of the divided parts of the glare shield frame is formed into a rabbet joint, each of which includes one or more tongues. Each of the tongues has an inward tapered waist portion and an outward projected hollow head portion in front of the waist portion. Two adjacent tongues together define a groove between them. The glare shield frame is divided at two diagonally opposite corners so as to produce two generally L-shaped parts. Each part of the glare shield frame is manufactured through punching with a punch machine. The rabbet joint at each connecting end of each divided part is formed at the time the part is punched or at other processing stage. By engaging, compressing and expanding two corresponding rabbet joints in two vertically opposite directions, the rabbet joints are bent.
