Problems solved by technology

When liquid optical glue LOCA or silica gel is used to bond the three-dimensional display functional device 14 and the 2D display module 12, the thickness control is completely dependent on the precision of the jig used. When the jig precision (such as surface flatness) is high When it is used, it can only guarantee the accuracy within ±10% of the design thickness, the cost of the fixture is high, and the effect after lamination is not ideal
like figure 2 As shown, when the three-dimensional display device using silica gel is hard-attached to separate the information corresponding to the left and right eyes (for example, the information for the left eye is all red, and the information for the right eye is all green), ideally the image seen at the set viewing position The red and green interface should be a straight line (indicated by a dotted line), but the actual situation is that the red and green interface is an arc (indicated by a solid line) in the figure, which means that the left eye information or right eye information has entered the user's right eye Or the left eye, which brings crosstalk, aggravates the ghosting of the stereoscopic display, and increases the user's discomfort

Abstract

The invention provides a three-dimensional device and a manufacturing method thereof, and relates to the technical field of three-dimensional display. The three-dimensional device includes a 2D display unit and a 3D functional device; a first substrate of the 2D display unit and a second substrate of the 3D functional device are fixedly connected through a bonding layer; and the bonding layer includes spacers and bonding glue. The spacers are added into the bonding layer arranged between the 2D display unit and the 3D functional device, the thickness of the bonding layer is even, and crosstalk of the three-dimensional device can be reduced.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to a stereoscopic display device and a manufacturing method. Background technique [0002] Among various stereoscopic display technologies, naked-eye 3D has become a hotspot in the research of 3D display technology due to the convenience of not needing other auxiliary equipment and its application advantages. The application of naked-eye 3D stereoscopic display devices in personal consumption fields such as mobile phones and tablets, and Applications in commercial display fields such as monitors and advertising machines are gradually increasing. At present, the technologies of naked-eye 3D display devices mainly include shape grating film technology, slit grating, liquid crystal lens and so on. [0003] In the production process of most stereoscopic display devices, it will involve hard sticking process, such as 3D functional devices such as liquid crystal slit...
