Abstract
A method of manufacturing micro-display includes the steps of testing individual chips on a base wafer forming the micro-display, and the tested “void” chips being marked, inputting the testing data into a sealant/glue machine and a laser puncher; sealant/glue forming on the external surrounding of a “passed” chip a sealant frame by the sealant/glue machine; forming an injection hole on an ITO glass panel at a position corresponding to the position of the “passed” chip, by means of the laser puncher; dispensing spacing particles within a chip's square box which has been formed with the sealant frame; position-aligning the ITO glass panel onto the wafer based on the wafer testing data; injecting a liquid crystal via the injection hole of the ITO glass panel located on the top layer of the “passed” chip to the space between the chips and the ITO glass; and sealing and dicing handling of the ITO glass panel to precisely manufacture the micro-display with a passed chip circuit so as to precisely screen the good products, and simplify the required number for fabrication and process.
