Multilayer light guide plate and manufacturing technology thereof

Abstract

The invention discloses a multilayer light guide plate comprising a left side frame, a right side frame and a multilayer light guide plate device which is arranged between the left side frame and theright side frame. The right side of the left side frame is provided with a left side clamp slot. The left side of the right side frame is provided with a right side clamp slot. The two ends of the multilayer light guide plate device are clamped in the left side clamp slot and the right side clamp slot. The multilayer light guide plate device comprises a transparent anti-fouling membrane, a prism sheet, a diffusion sheet, a first light guide plate, a second light guide plate and a reflecting sheet. The right side wall of the middle part of the left side frame is provided with an installing slotused for installing a lamp tube. The composite design of the transparent anti-fouling membrane, the prism sheet, the diffusion sheet, the first light guide plate, the second light guide plate and thereflecting sheet is used so that small dot intensive reflection can be effectively realized, light guiding of the light guide plate is enabled to be more uniform, the uniformity is higher and the performance is more stable. The high number of the layers of the light guide plate indicates the high number of the separable and controllable light emitting areas, and the control area of the brightnessis more delicate.

Description

technical field [0001] The invention belongs to the technical field of multilayer light guide plates, in particular relates to a multilayer light guide plate, and also relates to a manufacturing process of a multilayer light guide plate. Background technique [0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then high-tech materials with high reflectivity and non-absorbing light are used to engrave the bottom surface of the optical-grade acrylic sheet with laser, V-shaped cross grid engraving, UV screen printing technology prints light guide points. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide ...

Problems solved by technology

[0003] With the development of the mobile phone industry, the life cycle of mobile phones has been shortened sharply, and the market demand and types of mobile phone products are increasing day by day. The light guide plate is a necessary accessory in the manufacture of mobile phone products. Its lighting structure is a very precise part. Now Some light guide plates use a single light guide plate in their lighting structure, the light conductivity is not good, the light guide is uneven, and the installation and positioning of the light guide plate is difficult, which is not conducive to assembly
