Embodiment Construction

[0041] The 3D screensaver film is composed of a lenticular lens film (1), a low-refractive-index glue filling layer (15), a removable glue layer (16) and a tempered glass layer (17), among which the tempered glass layer (17) is not must. The removable adhesive layer (16) is attached to the screen of the mobile phone, and the convex surface of the lenticular lens film (1) can face away from the screen, such as Figure 7 As shown in A, it can also face the screen directly, such as Figure 7 Shown in B. The convex structure will affect the fit and touch quality, and the low-refractive index glue filling layer (15) is leveled to form a prism-free mirror grating, and the outer tempered glass layer (17) plays the role of support and anti-scratch. The refractive index of the low-refractive index glue is generally 1.3~1.4, and the refractive index of the lenticular lens grating layer is generally 1.50~1.7. The focal length meets the requirements of image focus. The 3D screen saver...

Abstract

The invention discloses a naked eye 3D display method. A 3D screen protection film is composed of a lenticular grating film (1), a low-refractive-index glue filling layer (15), a movable glue layer (16), a tempered glass layer (17) and other multi-layer structures, the viewing distance of 3D display is shortened to a normal handheld range by increasing the included angle theta between lenticular grating lines (7) and the vertical direction, and naked-eye 3D display can be achieved by externally pasting the screen protection film through handheld devices such as mobile phones and Pads. Meanwhile, the screen protection effect is achieved. A 3D grating film is attached to a smart phone, 3D shooting and display can be achieved in cooperation with a special APP, and meanwhile, 2D display and touch functions are not affected.

Description

Technical field: [0001] The invention relates to a naked-eye 3D display method, which can be used for 3D display of images and videos of personal handheld devices such as smartphones and PADs. Background technique: [0002] 3D grating is an important device to realize naked-eye 3D display. 3D grating mainly includes lenticular lens grating and slit grating, which are respectively simplified in one dimension according to the principle of convex lens imaging and pinhole imaging. An important characteristic of the 3D grating is: the light emitted by two adjacent pixels on the display plane passes through the optical center of a cylindrical mirror unit, or a slit, and then exits in a straight line, such as figure 1 shown. For the display screen on the handheld device, the viewing distance H≈350mm, the interpupillary distance L≈65mm, and the dot pitch p≈0.063mm of the 5.5-inch 1080P display screen, so the focal length D≈0.34mm of the 3D grating can be estimated. Considering the...
