Abstract: A color polymer dispersed liquid crystal display includes a lower substrate, an upper substrate, color liquid crystal-polymer films, and two transparent liquid crystal driving electrodes, among others. The color liquid crystal-polymer films are formed by foaming polymer films mixed with red, green and blue pigments to form porous films of red, green, and blue colors and then dropping and injecting liquid crystal into droplets of the porous films under vacuum condition. One of the two transparent liquid crystal driving electrodes is disposed between the lower substrate and the PDLC films, and the other is disposed between the PDLC films and the upper substrate. The changes in properties of the PDLC films, which may be caused by unstable phase separation in a conventional phase separation process, are reduced, and the colors are improved.

Abstract: Disclosed is a process for mounting chips exactly on a PCB without making a camera coordinate system coincide with a table coordinate system of a rotary-type chip mount system. The process comprises the steps of reading positional difference and angular difference between a camera coordinate system and a table coordinate system as values in the camera coordinate system by means of a jig nozzle, transforming the values to those of the table coordinate system, and using the transformed values as compensation data when mounting chips on PCB.
