Abstract
A rubbing system for an alignment layer of a liquid crystal display (LCD) device, comprises: a rubbing table on which a substrate having an alignment layer thereon is positioned; a rubbing roll on which a rubbing material is wound, substantially positioned on the rubbing table thus to substantially contact the alignment layer, for rubbing the alignment layer by rotation of the rubbing roll; and a controlling unit for controlling the alignment layer to be rubbed by substantially contacting the rubbing roll onto the alignment layer by simultaneously lifting and lowering a rubbing table and the rubbing roll according to an alignment controlling force to be applied to the alignment layer.
Claims39
A rubbing system for an alignment of a liquid crystal display device, comprising:
- a rubbing table on which a substrate having an alignment layer thereon is positioned;
- a rubbing roll on which a rubbing material is wound, substantially positioned on the rubbing table to substantially contact said alignment layer, for rubbing said alignment layer by rotation of said rubbing roll;
- and
- a controlling unit for controlling said alignment layer to be rubbed by substantially contacting said rubbing roll with said alignment layer by lifting and lowering said rubbing table and said rubbing roll according to an alignment controlling force upon said alignment layer.
A rubbing system for an alignment of a liquid crystal display device, comprising:
- a rubbing table on which a substrate having an alignment layer thereon is positioned;
- and
- a rubbing roll substantially positioned on said rubbing table thus to substantially contact said alignment layer for rubbing said alignment layer by rotation of said rubbing roll, wherein said alignment layer and said rubbing roll substantially contact each other such that both said rubbing table and said rubbing roll are driven.
A rubbing system for an alignment of a liquid crystal display device, comprising:
- a rubbing table on which a substrate having an alignment layer thereon is positioned;
- and
- a rubbing roll on which a rubbing material is wound, substantially positioned on said rubbing table thus to substantially contact said alignment layer, for rubbing said alignment layer by rotation of said rubbing roller, wherein said alignment layer and said rubbing roll substantially contact each other such that either said rubbing table or said rubbing roll is driven.
A method for rubbing an alignment layer of a liquid crystal display device, comprising:
- transferring a substrate on which an alignment layer is formed onto a rubbing table;
- inputting information relevant to said alignment layer;
- calculating a rubbing intensity applied to said alignment layer according to the alignment layer information;
- driving said rubbing table and rubbing roll according to the calculated rubbing intensity, and thus substantially contacting said rubbing roll with said alignment layer;
- and
- rubbing said alignment layer by rotating said rubbing roll.
A method for rubbing an alignment layer of a liquid crystal display device, comprising:
- transferring a substrate on which an alignment layer is formed onto a rubbing table;
- inputting information relevant to said alignment layer;
- calculating a rubbing intensity applied to said alignment layer according to the alignment layer information;
- driving at least one of said rubbing table and said rubbing roll according to the calculated rubbing intensity, and thus substantially contacting said rubbing roll with said alignment layer;
- and
- rubbing said alignment layer by rotating said rubbing roll.
A method for fabricating a liquid crystal display device, comprising:
- providing a first substrate on which a driving device array is formed and a second substrate on which a color filter layer is formed;
- forming a first alignment layer and a second alignment layer on the first substrate and the second substrate, respectively;
- positioning the first substrate and the second substrate on a rubbing table;
- inputting information relevant to said first alignment layer or information relevant to said second alignment layer;
- calculating a rubbing intensity applied to said first alignment layer or said second alignment layer according to the inputted alignment layer information;
- lifting and lowering at least one of said rubbing table and a rubbing roll according to the calculated rubbing intensity thereby substantially contacting said rubbing roll with said first alignment layer or said second alignment layer;
- rotating said rubbing roll thereby rubbing said first alignment layer or said second alignment layer;
- and
- attaching said first substrate and said second substrate to each other.
