Problems solved by technology

[0012] 1. Since the sheet optical elements 1 are stored in a vertical and horizontal arrangement, they are not suitable for automation
In particular, it is very difficult to automate the following process operations such as only taking out the sheet optical element 1 for processing and assembling.
[0013] 2. Since the protective film 31 has the same size as the optical sheet 1, it is difficult to peel off
[0016] Therefore, it is inconvenient to adopt such a large online storage interval

Embodiment 1

[0145] This embodiment is an example in which the present invention is specifically applied to an assembly of sheet-shaped optical elements in a backlight system of a liquid crystal screen of a handheld phone, a portable information terminal (device called a PDA, etc.), a digital camera, a portable game machine, and the like. Here, a prism sheet having light-collecting and refracting properties is used as the sheet-shaped optical element. The light collection and refraction of the prism sheet used as the sheet optical element used in this embodiment are designed to make the light of the light source evenly distributed on the liquid crystal screen, but it can also be designed to form various shapes on the screen according to other styles. light distribution. Refer to Figure 1 to Figure 4 .

[0146] In this embodiment, the assembled products are in a state of being sandwiched between protective sheets in a state of being neatly arranged in a certain direction. In particular,...

Embodiment 2

[0168] Refer below Figure 5 and Figure 6 Example 2 of the present invention will be described.

[0169] In this example, as using Figure 8 As described above, the first sheet-shaped optical element 1a and the second sheet-shaped optical element 1b perpendicular to the optical directionality of the first sheet-shaped optical element 1a are laminated in the above-mentioned order to obtain at least the above-mentioned laminated Structural part of the sheet optical element assembly.

[0170] refer to Figure 5 .

[0171] In this embodiment, the sheet optical element 1a, the second optical sheet element 1b perpendicular to the optical directionality thereof, and other diffuser sheets 7 required for constituting the sheet optical element assembly P should be placed relative to each other. The traveling direction D1 of their base film 2 is conveyed in the vertical direction D2, and on the base film 2, the sheet-shaped optical element 1a, the sheet-shaped optical element 1b, an...

Embodiment 3

[0208] Embodiment 3 of the present invention will be described below with reference to FIG. 7 .

[0209] In this example, as using Figure 8 As described above, the first sheet optical element 1a (front side) and the second sheet optical element 1b (back side) perpendicular to the optical directivity of the first sheet optical element 1a (back side) are laminated in this order. , to prepare an assembly for obtaining a sheet-shaped optical element assembly having at least the above-mentioned layered structure portion. In this embodiment, the diffusion sheet 7, the light guide plate 6, and the reflective sheet 5 are further stacked in this order to obtain the following Figure 8 The plate optic assembly of the illumination system shown.

[0210] Refer to Figure 7.

[0211] In this embodiment, a bracket 10 having sheet-shaped optical element assembly storage parts 10a to 10e composed of a plurality of recessed parts is used, and the sheet-like optical element assembly storage pa...

Abstract

A sheet-form optical element package body easy to handle, convenient to deliver and supply, and easy to process and assemble for potential automation, a method of using the sheet-form optical element package body, and a production method and device for the sheet-form optical element package body. 1) The sheet-form optical element package body comprises a plurality of sheet-form optical elements supported on a base film, and a protection film disposed on the optical elements, wherein the optical elements each having an optical orientation are disposed in a line on the base film, and the protection film / base film cover the entire upper surfaces of the optical elements with margins. 2) A method of using a sheet-form optical element comprises the steps of taking up the protection film with an upper roller and taking up the base film with a lower roller to thereby take out sheet-form optical elements for feeding to the next process. 3) A production method and a production device for the sheet-form optical element package body place two sheets of sheet-form optical elements on the base film with their optical directivities mutually orthogonal to each other.

Description

technical field [0001] The present invention relates to a sheet-shaped optical element assembly, a method of using the sheet-shaped optical element, a manufacturing method of the sheet-shaped optical element assembly, and a manufacturing device of the sheet-shaped optical element assembly. The sheet-like optical element assembly of the present invention is a structure in which the sheet-like optical element is supported on a protective member or the like. An assembly of structures in which sheet-shaped optical elements are processed. Background technique [0002] Conventionally, it has been known that optical elements are formed into sheets for various purposes. For example, a Fresnel lens has been known since ancient times as a film-shaped lens. Furthermore, there is also known a sheet-shaped optical element called a prism sheet in which prisms are formed into a sheet. Furthermore, there is also known a sheet-like microlens. [0003] Previously, sheet optical components...
