specific Embodiment approach 1

[0064] Specific embodiment one, polarized three-dimensional sheet manufacturing method comprises the following steps:

[0065] Step 1. Paste the half-wave plate on the flat substrate surface;

[0066] see figure 1 , paste the half-wave plate 3 on the flat base 1 through the adsorption layer 2, the area of ​​the base 1 is larger than the area of ​​the half-wave plate, the purpose of setting the base 1 is to fix the half-wave plate 3 , for subsequent cutting.

[0067] In this step, electrostatic adsorption, vacuum adsorption or low-adhesive adhesive is used, and the purpose of using the low-adhesive adhesive is to facilitate removal of the substrate 1 in subsequent steps.

[0068] Step 2. Cut the half-wave plate according to the preset pattern to form a patterned structure;

[0069] The cutting process of this step only cuts through half of the wave plate, while keeping the integrity of the substrate; using die cutting, roll cutting, scribing, laser cutting, etc., only half o...

[0091] Specific embodiment two, the manufacture method of polarized three-dimensional film, this method comprises the following steps:

[0092] Step 1. Paste the half-wave plate on the flat substrate surface;

[0093] Step 2. Cut the half-wave plate according to the preset pattern to form a patterned structure;

[0094] The cutting process of this step only cuts through half of the wave plate, while keeping the integrity of the substrate;

[0095] Step 3, peeling off the invalid area in the patterned structure from the surface of the substrate;

[0096] Step 4, affixing the half-wave plate side of the patterned structure after the peeling treatment to the linear polarizer;

[0097] The bond strength between the half-wave plate and the linear polarizer is greater than the bond strength between the half-wave plate and the substrate;

[0098] Step 5. Remove the substrate to expose half of the wave plate;

[0099] Step 6, bonding the linear polarizing film to the exposed half ...

Embodiment

[0113] Example: Taking the LED with a P2 dot pitch as an example, the first implementation mode is adopted. In order to reduce the horizontal visual stripes of the product, half of the wave plate adopts a wave pattern such as image 3 As shown, it is carried out by laser cutting. The flat substrate is made of 0.25mm thick PET film with silica gel on the surface of the PET film. Use a laminating machine to attach the patterned half-wave plate to the silica gel surface of PET. Remove the unnecessary half-wave plate; laminate the linear polarizer with the pressure-sensitive adhesive oca layer and the PET with the half-wave plate through the laminating machine, because the pressure-sensitive adhesive oca and the two The bonding force of the quarter-wave plate is greater than that of the half-wave plate and the PET silica gel layer, so it is easy to peel off the PET with silica gel, and then the quarter-wave plate and the half of the above combined film The surface of one wave plat...

Abstract

A stereoscopic polarizer and a manufacture method thereof, and a 3D (three-dimensional) LED and a manufacture method thereof belong to the technical field of stereo display. The invention is intendedto solve the problem that existing 3D glasses are high in maintenance cost and easily cause back sight. The manufacture method of the stereoscopic polarizer comprises the steps of I, attaching a halfwave plate to the surface of a flat substrate; II, cutting the half wave plate according to a preset pattern to form a patterned structure; III, stripping an ineffective area of the patterned structure from the surface of the substrate; IV, attaching the half wave plate side of the patterned structure, which is stripped, to a linear polarizer in aligned manner; V, removing the substrate to exposethe half wave plate; VI, pasting a quarter wave plate to the exposed half wave plate via OCA (optically clear adhesive) or LOCA (liquid optical clear adhesive) so as to obtain the stereoscopic polarizer, wherein the adhesive also fills a gap caused by the ineffective area of the stripped half wave plate.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and relates to the manufacturing technology of a polarizing stereoscopic sheet. Background technique [0002] Restoring reality has always been the goal pursued by human beings. There will be a technological revolution every ten years. In 1999, 3D projection was popular in various science and technology museums, museums and other places; in 2009, driven by Avatar, the market share of 3D TV surged; As the dot pitch of LED becomes smaller, the cost is reduced, the stability is improved, and the brightness is high. Therefore, 3D LED is bound to be a development trend, and it is also an inevitable trend to enter theaters to replace traditional expensive screens. [0003] Glasses-type 3D display technology has almost no technical defects except for the need to wear glasses. Glasses-type 3D is mainly divided into shutter glasses (active glasses-requires charging) and polarized glasses (pas...
