AI Technical Summary
Technical Problem
The backlit touchpad design in traditional gaming laptops produces excessively bright and direct light, causing eye strain for users.
Method used
The light weakening component is arranged in a stacked configuration of a semi-transparent glass cover, a light weakening component, a diffusion component, a first light guide component, a reflection component, and a circuit board component. After the light source shines on the first light guide component from the side, the light weakening component diagonally scatters the light upward to prevent the light from shining directly into the eyes.
Benefits of technology
It effectively solves the problem of glare from the illuminated touchpad, preventing light from shining directly into the user's eyes and reducing visual fatigue.

Abstract
The utility model provides a backlight touch panel structure based on an optical filter eye protection function, which relates to the technical field of computers and comprises a semi-transparent glass cover plate, a light weakening component, a diffusion component, a first light guide component, a reflection component and a circuit board component. The semi-transparent glass cover plate, the light weakening assembly, the diffusion assembly, the first light guide assembly, the reflection assembly and the circuit board assembly are sequentially arranged in a stacked mode and fixedly connected in a bonding mode, and after a light source irradiates the first light guide assembly from the side face, the light weakening assembly can scatter light guided by the first light guide assembly obliquely upwards. The backlight touchpad structure based on the optical filter eye protection function can effectively solve the problem that light rays of a light-emitting touchpad are dazzling.
