Patent ID: 8593613

Claim:
An LCD exposure stage device, comprising: a stage, having an upper surface that makes contact with a bottom surface of a substrate; a plurality of moving pins, being disposed flat on the upper surface of the stage and distributed at sides of the substrate; and a plurality of driving mechanisms, being connected to the moving pins distributed at the sides of the substrate respectively and being adapted to drive the moving pins to make contact with side surfaces of the substrate so as to move the substrate; wherein the stage is formed with a plurality of vent holes, and a lower venting end of each of the vent holes communicates with and external air blowing/sucking device through a venting pipe; air is blown by the external air blowing/sucking device into the vent holes to apply a force, which is slightly grater than or equal to the gravity of the substrate, to the substrate placed above the vent holes so that the substrate is lifted upwards slightly; the substrate is substantially kept in contact with the stage during moving an exposure processes.
