Notebook computer optical film with fluctuating structure

Abstract

The invention relates to the technical field of optical films, and discloses a notebook computer optical film with a fluctuating structure, which comprises a shell, an optical film is arranged in the shell, a screw rod is rotatably connected in the shell, a speed limiting box is arranged in the shell, a fixed column is fixedly connected in the speed limiting box, and the exterior of the speed limiting box is rotationally connected with a rotating disc. According to the notebook computer optical film with the fluctuating structure, through the design of the fluctuating structure between a light condensation structure I and a light condensation structure II, the concealing effect of the notebook computer optical film is better, and Newton rings, light reflection phenomena and the like can be improved; and the rotating disc is driven to rotate to drive a trapezoidal plate to rotate, after the trapezoidal plate drives the pushing plate to rotate, the optical film can be wound, the situation that the winding efficiency becomes low due to manual operation is avoided, and therefore the effect that the optical film winding efficiency can be improved is achieved.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to an optical film for notebook computers with a high and low undulating structure. Background technique [0002] Optical film is a kind of optical medium material that is composed of thin layered medium and transmits light beam through the interface. The application of optical films began in the 1930s. In modern times, optical thin films have been widely used in the fields of optics and optoelectronics to manufacture various optical instruments, including notebook computers. [0003] There are following defects and deficiencies in the prior art: [0004] 1. In order to reduce the cost of traditional notebook computer optical films, the industry is committed to reducing the number of optical films in the backlight module. Many liquid crystal displays have canceled the use of the upper diffuser. Defects such as iridescent patterns and reflections are easy to be observed, the...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a notebook computer optical film with a high and low undulating structure, which can solve the problems of the existing traditional notebook optical film, such as rainbow patterns and reflections, which are easy to be observed and traditional winding. The device cannot guarantee the safety of the optical film; this device can effectively solve the problem by setting a high and low undulating light-gathering structure and a speed-limited winding device
