Liquid crystal adjustment device, crystal display panel and method for adjusting amount of liquid crystals in liquid crystal display panel

A method for adjusting an amount of liquid crystals in a liquid crystal display panel, comprising:

• injecting liquid crystals into the liquid crystal cell or expelling liquid crystals from the liquid crystal cell by utilizing a liquid crystal accommodation space in a liquid crystal adjustment device which is in communication with a liquid crystal cell of the liquid crystal display panel;
• detecting, by a first detection unit, a change of an amount of liquid crystals in the liquid crystal cell;
• and
• adjusting, by a first adjustment unit, the amount of the liquid crystals in the liquid crystal cell based on the change of the amount of the liquid crystals in the liquid crystal cell,
• wherein a composition material of the first adjustment unit comprises an extendable and retractable material, the length of the extendable and retractable material is changed under the control of voltage or temperature, or
• a composition material of the first adjustment unit comprises an expandable material, the volume of the expandable material is changed under the control of voltage or temperature.
