The invention discloses a processing device and method for precise alignment and lamination under the liquid level. The processing device and method is suitable for electronic fluid display processing. The device comprises a water trough for a lower substrate to be arranged, a conveying belt for conveying an upper substrate, a flat plate type suction head for sucking the upper substrate, a positioning CCD video camera for positioning the upper substrate and the lower substrate and an illuminating system, wherein the lower surface of the flat plate type suction head serves as a working face, array type suction holes are formed in the working face and communicated with vacuum tubes, and an annular lamination brim is arranged on the peripheral edge of the working face of the flat plate type suction head and surround the suction holes in the circle formed by the annular lamination brim. When the device is applied, the processing device for precise alignment and lamination under the liquid level has the advantages of being high in production efficiency, convenient to apply and the like, the prior art does not have.
Description
technical field [0001] The invention relates to a production equipment of an electrowetting display device, in particular to a process equipment and method for precision alignment and bonding under a liquid surface. Background technique [0002] The biggest difference between the front plate process technology of the electrowetting display device (Electronic fluid display, referred to as EFD) and the traditional LCD process technology is that the filling and packaging environment is placed below the liquid level of the electrolyte solution; the bonding of the upper substrate and the lower substrate At the same time, it is necessary to solve the special problems of grasping and releasing the upper substrate in the liquid environment, the precise visual alignment of the optical image penetrating through the multi-layer medium, and the uniform control of the pressing force; however, there is currently no special production equipment for this on the market , thus resulting in lo...
