Abstract
Liquid crystal material is introduced into a liquid crystal panel having upper and lower substrates and a seal pattern having an injection port at a peripheral portion thereof including, preparing an open portion that elongates from the injection port to a side of the lower substrate. The liquid crystal material is in a tray having a protruded portion corresponding in shape to the open portion. The protruded portion of the tray is inserted into the injection port, so that the liquid crystal material in the tray can be injected into the panel through the protruded portion and the injection port. After the injection process, there is no need to clean the panel, because liquid crystal material does not contaminate the outside of the panel.
Claims19
A method of filling a liquid crystal material into a liquid crystal display panel which comprises:
- providing the liquid crystal display panel having an upper substrate, a lower substrate and a seal pattern having an injection port at a peripheral portion of the seal pattern;
- preparing an indentation that is indented from a side of the lower substrate to the injection port;
- providing a tray having a protruded portion corresponding to the open portion;
- filling the tray with the liquid crystal material;
- inserting the protruded portion into the injection port;
- and
- introducing the liquid crystal material into the liquid crystal display panel through the protruded portion and the injection port.
A liquid crystal display panel comprising:
- an upper substrate;
- a lower substrate assembled with the upper substrate, the lower substrate having an indentation that is indented from a side of the lower substrate to an injection port;
- liquid crystal material interposed between the upper and lower substrates;
- and
- a seal pattern formed between the upper and lower substrates, the seal pattern having an injection port.
A tray for filling a liquid crystal material into a liquid crystal panel, the liquid crystal panel comprising an upper substrate, a lower substrate, a seal pattern having an injection port at a peripheral portion of the seal pattern, and an indentation that is indented from a side of the lower substrate to an injection port, the tray comprising:
- a body defining a cavity therein;
- and
- a protruded portion extending from said body and corresponding to the indentation of the liquid crystal panel.
A system for filling a liquid crystal material into a liquid crystal panel, the system comprising:
- a liquid crystal display panel including:
- an upper substrate;
- a lower substrate assembled with the upper substrate, the lower substrate having an indentation that is indented from a side of the lower substrate to an injection port;
- liquid crystal material interposed between the upper and lower substrates;
- and
- a seal pattern formed between the upper and lower substrates, the seal pattern having the injection port;
- and
- a tray including:
- a body defining a cavity therein;
- and
- a protruded portion extending from said body and corresponding to the indentation of the liquid crystal display panel.
