#CMT# #/CMT# A substrate bonding device for fabricating liquid crystal display panel, comprises a lower chamber unit on base frame with upper surface; an upper chamber unit with lower surface; chamber moving mechanism for raising and lowering upper chamber unit; an upper stage for securing first substrate; a lower stage for securing second substrate; and a seal for sealing interior space around substrates. #CMT# : #/CMT# A substrate bonding device for fabricating a liquid crystal display (LCD) panel, comprises a base frame (100); a lower chamber unit (220) mounted to the base frame, having an upper surface; an upper chamber unit (210) arranged over the lower chamber unit, which is moveable relative to the base, and has a lower surface; chamber moving mechanism mounted to the base frame for raising and lowering the upper chamber unit; an upper stage (230) fixed to the upper chamber unit (212) for securing a first substrate; a lower stage (240) fixed to the lower chamber unit (222) for securing a second substrate; and a sealing mechanism provided to the upper and/or lower surfaces for sealing an interior space surrounding the first and second substrates. The sealed interior space is definable by joined upper and lower chamber units. An independent claim is included for a method for fabricating a liquid crystal display (LCD) panel using a substrate bonding device as above, comprising loading the first and second substrates onto the upper and lower stages, respectively; lowering the upper chamber unit to seal the interior space from an external environment via the sealing mechanism; evacuating the sealed interior space; raising the upper chamber unit and the upper stage to align the first and second substrates; contacting the first and second substrates with a sealant material; venting the sealed interior space to apply pressure to the first and second substrates contacted by the sealant material, where, after venting, the first and substrates are bonded together; and unloading the bonded substrates. #CMT#USE : #/CMT# For fabricating a liquid crystal display panel (claimed). #CMT#ADVANTAGE : #/CMT# The substrate bonding device has reduced and simplified overall structure, such that a layout of the liquid crystal display fabrication process may be simplified. The device provides smooth alignment between substrates and the period of time required to fabricate a single LCD panel may be reduced to facilitate smooth progression of processing and subsequent liquid crystal fabrication processes. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a substrate bonding device for fabricating LCD panels in an unloaded state. 100 : Base frame 210 : Upper chamber unit 211 : Upper base 212 : Upper chamber unit 220 : Lower chamber unit 221 : Lower base 222 : Lower chamber unit 230 : Upper stage 240 : Lower stage #CMT#MECHANICAL ENGINEERING : #/CMT# Preferred Device: The device further comprises photosetting mechanism(s) provided to at least one of the chamber units for partially hardening a sealant material between the first and second substrates. Preferred Component: The upper stage includes a fixing plate fixed to the bottom surface; a securing plate for securing the first substrate; and fixing blocks between the fixing plate and the securing plate. The photosetting mechanism includes an ultraviolet directing part for directing UV light. The first and second substrates include a thin film transistor array substrate, or a color filter array substrate. Preferred Material: The sealant material includes an ultraviolet photosetting sealant and/or a thermosetting sealant. Preferred Method: The method further comprises providing venting holes within the upper and lower stages; providing low vacuum chamber pipelines to the sealed interior space; and directing ultraviolet light to the sealant material for partially hardening the sealant material. The venting includes injecting nitrogen gas into the sealed interior space through the venting holes provided within the upper and lower stages; and injecting nitrogen gas through the low vacuum chamber pipelines to increase the pressure inside the sealed interior space equal to atmospheric pressure. The ultraviolet light is directed to 10 regions of the sealant material. #CMT#POLYMERS : #/CMT# Preferred Material: The securing plate includes polyimide. |
