Abstract

Liquid crystal depositing devices and methods that monitor the amount of the liquid crystal available for dispensing and supplement the liquid crystal when the device detects that the amount available is running low. One exemplary liquid crystal depositing device includes a liquid crystal dispensing container, a liquid crystal nozzle, a liquid crystal sensor, and a liquid crystal supplementing container. The liquid crystal nozzle deposits the liquid crystal from said liquid crystal container to the liquid crystal display substrate. The liquid crystal sensor is configured to monitor an amount of liquid crystal inside the liquid crystal dispensing container. The liquid crystal supplementing container is configured to supply liquid crystal to the liquid crystal dispensing container when the liquid crystal sensor detects that the amount of liquid crystal in the dispensing container has fallen below a predetermined amount. In one exemplary method, a detected amount of liquid crystal in a liquid crystal dispensing container is compared to a predetermined sufficient liquid crystal amount. The liquid crystal in the liquid dispensing crystal container is supplemented when the liquid crystal amount in the liquid crystal dispensing container is below the predetermined sufficient liquid crystal amount. The liquid crystal is deposited onto a liquid crystal display substrate when the liquid crystal amount in the liquid crystal dispensing container is above the predetermined sufficient liquid crystal amount.
