Abstract
A liquid crystal material dispensing apparatus includes a spacer height measuring unit for measuring a height of a spacer on a substrate, and a liquid crystal material dispensing system for determining an amount of the liquid crystal material to be dispensed on the substrate based upon the measured spacer height and for dispensing the liquid crystal material onto the substrate.
Claims31
A liquid crystal material dispensing apparatus, comprising:
- a spacer height measuring unit for measuring a height of a spacer on a substrate;
- and
- a liquid crystal material dispensing system for determining an amount of the liquid crystal material to be dispensed on the substrate based upon the measured spacer height and for dispensing the liquid crystal material onto the substrate.
A liquid crystal material dispensing apparatus, comprising:
- a liquid crystal material dispensing system for dispensing the liquid crystal material onto a substrate with a predetermined pattern;
- and
- a control unit for calculating a compensated amount of the liquid crystal material by calculating a dispensing amount of the liquid crystal material based on an input spacer height and comparing the calculated dispensing amount of the liquid crystal material with a predetermined dispensing amount of the liquid crystal material, and for controlling an amount of the liquid crystal material dispensed onto the substrate.
A method for dispensing liquid crystal material, comprising:
- measuring a height of a spacer on a substrate;
- calculating a dispensing amount of the liquid crystal material based on the measured spacer height;
- and
- dispensing the calculated amount of the liquid crystal material onto the substrate.
A method of dispensing liquid crystal material comprising:
- inputting a height of a spacer on a substrate;
- calculating a dispensing amount of the liquid crystal material based on the inputted spacer height and calculating a compensated amount of the liquid crystal material by comparing the calculated dispensing amount of the liquid crystal material with a predetermined dispensing amount of the liquid crystal material;
- and
- dispensing the liquid crystal material onto the substrate, the liquid crystal material having an amount obtained by applying the calculated amount of the liquid crystal material compensated to the dispensing amount of the liquid crystal material.
