Abstract
The module includes a liquid crystal faceplate, a base, and an outline border bonded the base. Multiple pieces of polycrystalline film with spacer connected electrically are installed on selected side of the liquid crystal faceplate. The base possesses accommodation space enclosed by stand-up sidewalls for the liquid crystal faceplate to be placed. Position-limited parts are setup at outside of the vertical sidewalls corresponding to places, where pieces of polycrystalline film are installed. Multiple pieces of polycrystalline film are bent and constrained on position limited parts so that in procedure of assembling module, pieces of polycrystalline film will not be scratched caused by pressing outline border together. Therefore, unflavored influence on polycrystalline film in assembled module caused by vibration of force can be avoided, so as to raise ratio of fine products.
