Description
Technical field
The present invention relates to the contraposition patch of a kind of manufacture method of display, more particularly to a kind of 3D lens and flat-panel monitor
Conjunction method and contraposition laminating apparatus.
Background technology
In order to realize the three-dimensional display with naked eye 3 D function, 3D lens (including automatically controlled liquid crystal lens or general post
Shape lens) often it is arranged on the front of a flat-panel monitor.3D lens generally comprise multiple micro- lens pillars side by side, when setting
Put flat-panel monitor and 3D lens apart from when, the difference that micro- lens pillar diverse location is corresponded in flat-panel monitor can be made
Pixel (left pixel, right pixel can be divided into) project respectively on different directions, thus human eye watch when, its different pixels institute
The content of display, it can respectively enter in right and left eyes, to realize 3D visions.
However, in order that the content shown by different pixels projects in the right and left eyes of people exactly, it is micro- in 3D lens
The pixel of lens pillar and flat-panel monitor needs extremely accurate to be aligned, at present, typically by be arranged on 3D lens with
Alignment mark in flat-panel monitor realizes, however, due to deviation be present between alignment mark and pixel and 3D lens, it is this
Method can not directly reflect final 3D effect, cause between the axis of made three-dimensional display out and right and left eyes
Axis be difficult to proper alignment, its 3D image can not often project in the right and left eyes of user exactly, 3D visual effects
It is poor.
The content of the invention
The technical problem to be solved in the present invention is to provide the contraposition applying method of a kind of 3D lens and flat-panel monitor and
Laminating apparatus is aligned, the contraposition applying method of this 3D lens and flat-panel monitor can make 3D lens and flat-panel monitor more accurate
Really align so that 3D left and right image can be projected relatively accurately in the right and left eyes of user, increased substantially 3D and regarded
Feel effect.The technical scheme of use is as follows：
A kind of contraposition applying method of 3D lens and flat-panel monitor, it is characterised in that comprise the following steps：
