A cylindrical lens type naked eye 3D module

Abstract

The invention discloses a lenticular-lens-type naked eye 3D module. The lenticular-lens-type naked eye 3D module is sequentially provided with grating glass, a base material and a liquid crystal screen from top to bottom. Double-faced adhesive tape layers are arranged on both the top face of the base material and the bottom face of the base material. The lenticular-lens-type naked eye 3D module further comprises a concave metal plate frame. A groove of the concave metal plate frame is used for limiting and locking an assembly formed by the grating glass, the base material, the double-faced adhesive tape layers and the liquid crystal screen. The size of the inner groove wall of the groove of the concave metal plate frame is matched with the thickness of the assembly formed by the grating glass, the base material, the double-faced adhesive tape layers and the liquid crystal screen. Filling adhesive layers are arranged in gaps existing between the liquid crystal screen, the grating glass and the concave metal plate frame. According to the lenticular-lens-type naked eye 3D module, limiting of the grating glass is realized through the concave metal plate frame and appropriate filler, the parameter stability of the module is guaranteed, and the assembly alignment precision and the 3D display effect are indirectly improved.

Description

Technical field [0001] The present invention relates to the field of 3D display device manufacturing, in particular to a cylindrical lens type naked eye 3D module. Background technique [0002] Cylindrical naked-eye 3D display technology is a display technology that uses the principle of light splitting of cylindrical lenses to make the images entering the observer’s left and right eyes have a certain difference, thereby forming a three-dimensional sensation in the observer’s brain. It is currently the mainstream technology in the naked-eye 3D industry one. As people’s requirements for display devices are getting higher and higher, lenticular glasses-free 3D display devices are widely used in airports, hotels, advertising and other industries with very broad application prospects. [0003] Among them, the key component of the lenticular naked-eye 3D display device is the naked-eye 3D module, which can realize 3D display with certain circuits and chip sources. The lenticular glass...
