Abstract

A touch control device and a smart mirror provided by an embodiment of the present invention, the touch control device includes: a birefringent film layer in a touch function layer, a cover glass layer and an anti-glare layer; the anti-glare layer is arranged on the touch Between the functional layer and the cover glass layer; the anti-glare layer of the embodiment of the present invention can scatter the light emitted by the touch functional layer, eliminate the rainbow pattern formed by the touch functional layer, and improve the display performance of the touch device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device touch device and a smart mirror. Background technique [0002] Rainbow pattern is an optical phenomenon that appears after some LCD screens are turned on. The angle perpendicular to the screen is 0°, and the angle parallel to the screen is 90°. Rainbow patterns usually appear symmetrically on both sides of the screen at greater than 45°, showing Colorful circular stripes resembling Newton's rings. Rainbow pattern is an optical phenomenon unique to birefringent materials. The refracted light inside the birefringent material is reflected multiple times on the upper and lower surfaces of the material. When the reflected light meets the optical path difference, interference phenomenon will occur, thus forming rainbow pattern. [0003] The smart mirror is a touch LCD display using high-reflectivity anti-reflection glass as the cover glass, which can play the...
