Description
Technical field
The present invention relates to a kind of exposure machine and exposure system, and particularly relate to a kind of exposure machine and exposure system of the exposure of layering simultaneously multi-disc display panels.
Background technology
In recent years LCD (liquid crystal display, technology LCD) is progressive fast, for the key parameter of liquid crystal indicator quality, for example improved space is there's no one who doesn't or isn't actively sought in reaction time, visual angle, brightness, contrast etc.
In view of this, auto polymerization macromolecule auxiliary ligand is to (polymer stabilized alignment, PSA) after technology is suggested to, since the display panels of this technology manufacturing have fast-response time, with great visual angle, advantage such as high aperture (high-luminous-efficiency), high contrast and technology is simple, since open, be subjected to suitable attention always, be regarded as to become the mainstream technology in the liquid crystal indicator of future generation market.
And in the PSA technology, it is mainly at multi-zone vertical alignment nematic (multi-domain vertical aligned, MVA) add micro-response type monomer (reactive monomer) in the type liquid crystal, and under the irradiation that applies voltage and ultraviolet light (UV light), the response type monomer can the concurrent looks segregation phenomenon of polymerization reaction take place.When polymerizable molecular is piled up at the interface, because polymerizable molecular is with the interaction force of liquid crystal molecule between, make polymerizable molecular arrange and pile up, thereby make the liquid crystal molecule in the panel on certain orientation, have tilt angle (pre-tile angle) along the liquid crystal molecule direction.And this tilt angle is except the toppling direction of decision display panels liquid crystal molecule by driven time the, the also light transmission capacity of direct relation liquid crystal molecule under different driven.
Yet if when applying voltage and UV light exposure technology for the first time, monomer is complete reaction not, and the monomer that residues in the panel is subjected to further reaction under the extraneous irradiate light easily.To have influence on the tilt angle of liquid crystal molecule thus, cause tilt angle local distribution inequality, and have panel optical property instability and ghost problems such as (image sticking) to take place.And the ghost of this type that is taken place, mainly be because due to the liquid crystal molecule tilt angle difference, be can't be restorative flaw, and in panel shows, very easily be found especially, under the quality requirements more and more harsh in the face of display panels, will become the mainstream technology with practicality and volume production but this type is added the LCD Technology of response type monomer, the ghost problem that solves because of micro-monomer residue caused is inevitable.
Summary of the invention
In view of this, purpose of the present invention is exactly in that a kind of exposure machine and exposure system are provided, and in photochemically reactive mode, the residual monomer in the display panels that adds the response type monomer can complete reaction be finished.
According to purpose of the present invention, a kind of exposure machine is proposed, be used at least one first display panels and one second display panels are exposed, comprise a body and at least one first exposure source and one second exposure source.Body has at least one first platform and one second platform, and second platform is positioned under first platform, and first display panels and second display panels are placed in respectively on first platform and second platform.First exposure source and second exposure source are arranged at respectively on first platform and second platform, in order to first display panels and second display panels of exposing respectively.
According to purpose of the present invention, a kind of exposure system is proposed, comprise a plurality of platforms, a plurality of display panels and at least one exposure source.A plurality of platforms are positioned on the Different Plane, and a plurality of display panels are arranged on the platform.At least one exposure source is arranged at the platform top, in order to the display panels that exposes respectively.
