Reference aligning method and aligning system for machine manufacturing

Abstract

The invention relates to a reference aligning method and aligning system for machine manufacturing. The reference aligning method for machine manufacturing comprises the following steps: forming a reference in or on an exposure sensitive layer on a workpiece by using a dry method; measuring and recording the positional information of the reference in a first coordinate system used by a writing system so as to apply first exposure to the workpiece; searching for a reference line of a pattern retarder and allowing the reference line to be a predetermined distance away from one of a plurality of nominal patterns formed at the upper end and lower end of the pattern retarder; aligning the reference line of the pattern retarder with the positional information of a display board in the first coordinate system; and when the reference line of the pattern retarder is aligned with the first positional information and second positional information of the display board in an allowable alignment error range, attaching the pattern retarder to the display board. The reference aligning method can realize reference aligning of machine manufacturing.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an alignment reference method and an alignment system for mechanical manufacturing. Background technique [0002] A stereoscopic image display device displays a 3D image using a stereoscopic technique or an autostereoscopic technique. Stereoscopic technology exploits the parallax between the left and right eyes and may or may not use special glasses to provide the 3D effect. When using certain glasses, a viewer sees a 3D image through polarization glasses or shutter glasses since a direct emission type display device or a projector displays left and right images in a manner in which polarization directions of the left and right images are changed or in a time-division manner. In the absence of glasses, optical components such as parallax barriers or lenticular lenses are mounted in front or behind the display to separate the optical axes of the left and right images.

Problems solved by technology

Although not requiring any polarization separation element, the shutter glass type stereoscopic image display device suffers from high price due to expensive shutter glasses

From the standpoint of 3D image quality, the shutter glasses type stereoscopic image display device is disadvantageous because the left and right eye images are subjected to time division with a predetermined time interval, which increases flicker and 3D crosstalk compared with the polarized glasses type display device, thereby causing viewing increased fatigue
