Abstract
A method for withdrawing a liquid crystal from a liquid crystal panel includes the steps of: (a) providing a liquid crystal panel that includes a liquid crystal and two spaced-apart substrates cooperatively defining an accommodating space therebetween to accommodate the liquid crystal, and that is divided into a discard region and a reserve region; (b) forming a through hole that is located in the discard region in one of the substrates; and (c) liquefying the liquid crystal that is accommodated in the accommodating space, followed by withdrawing the liquid crystal from the accommodating space through the through hole. A method for recycling a liquid crystal panel is also disclosed.

A method for withdrawing a liquid crystal from a liquid crystal panel, comprising the steps of:
- (a) providing a liquid crystal panel that includes a liquid crystal and two spaced-apart substrates cooperatively defining an accommodating space therebetween to accommodate the liquid crystal, and that is divided into a discard region and a reserve region;
- (b) forming a first through hole that is located in the discard region in one of the substrates;
- and
- (c) liquefying the liquid crystal that is accommodated in the accommodating space, followed by withdrawing the liquid crystal from the accommodating space through the first through hole.
A method for recycling a liquid crystal panel, comprising the steps of:
- (a) providing a liquid crystal panel that includes a liquid crystal and two spaced-apart substrates cooperatively defining an accommodating space therebetween to accommodate the liquid crystal, and that is divided into a discard region and a reserve region;
- (b) forming a first through hole that is located in the discard region in one of the substrates;
- (c) liquefying the liquid crystal that is accommodated in the accommodating space, followed by withdrawing the liquid crystal from the accommodating space through the first through hole;
- (d) cutting the liquid crystal panel so as to separate the discard region and the reserve region, the reserve region having a cutting surface that is formed with a slot exposing the accommodating space of the reserve region;
- (e) filling a liquid crystal into the accommodating space of the reserve region through the slot;
- and
- (f) sealing the slot of the cutting surface using a sealant so as to seal the liquid crystal in the accommodating space of the reserve region.
