Abstract
A fabricating method of a liquid crystal display panel provides a first substrate and a second substrate. The first substrate has a sealant used for sealing with the second substrate to form a liquid crystal cavity. The first substrate and the second substrate are placed into a chamber to perform a liquid crystal filling process. An end seal process is performed at a predetermined temperature higher than room temperature to seal the liquid crystal with a predetermined weight into the liquid crystal cavity. A liquid crystal injection method, an end seal process, and heating apparatus are also provided.
Claims25
A method of manufacturing a liquid crystal display panel, comprising:
- providing a first substrate and a second substrate, the first substrate having a first sealant used for sealing with the second substrate to form a liquid crystal cavity;
- placing the first substrate and the second substrate in a chamber to perform a liquid crystal filling process;
- and
- performing an end-seal process at a predetermined temperature higher than room temperature to seal the liquid crystal with a predetermined weight into the liquid crystal cavity,
- wherein the end-seal process comprises:
- heating the first and the second substrate to the predetermined temperature;
- applying a first predetermined pressure to the first and the second substrate;
- maintaining the predetermined temperature and the first predetermined pressure for a first time period;
- reducing the first predetermined pressure applied to the first and the second substrate to a second predetermined pressure;
- sealing the first and the second substrate at the predetermined temperature;
- maintaining the predetermined temperature and the second predetermined pressure for a second time period;
- and
- removing the second predetermined pressure and lowering the predetermined temperature to room temperature.
