Abstract
A liquid crystal micro display (lcmd) is manufactured by creating a hole in an lcmd surface, filling the lcmd with liquid crystal material through the hole, and then sealing the hole. The invention allows an lcmd to be tested before it is separated from other lcmds and packaged. As a result, the invention increases the yield and reduces the cost associated with lcmd manufacturing.
