Section material strip having light-resistant function and optical touch frame

Abstract

The invention provides a section material strip having a light-resistant function. A covering part and a reflecting light-absorbing part are embedded in the section material strip, the outer surface of the covering part and the inner surface of the section material strip are arranged on the same plane, the covering part covers the top of the reflecting light-absorbing part, and the reflecting light-absorbing part has the same length as the covering part. An optical touch frame with the section material strip comprises two longitudinal section material strips, two horizontal section material strips, a left optical touch module, a right optical touch module and a reflective strip, wherein the longitudinal section material strips and the horizontal section material strips are made of the section material strip. According to the section material strip, the touch effect cannot be influenced by sunlight disturbance. When the section material strip is in use, a background image is formed by an image which is partially bright and partially dark, a touched object can be distinguished out of the background image no matter whether the sun shines the touched object, and the touch effect cannot be disturbed by light from the sun and the like.

Description

technical field [0001] The invention relates to the field of optical touch technology, in particular to an optical touch frame, in particular to a profile bar and an optical touch frame with anti-light function. Background technique [0002] At present, more and more scenes need to use touch TVs, such as interactive touch advertising machines, interactive electronic information screens, etc., but in the promotion of such outdoor touch displays, the existing technology has poor resistance to sunlight interference. fatal flaw. [0003] The reasons are as follows: [0004] When there is no sunlight interference, the background image is a group of relatively bright images, and the touch object at this time is imaged as a relatively dark data; but when the sun shines on the touch object, the touch object will be illuminated, and at the same time Reflecting strong infrared light into the space causes the image of the touched object in the optical sensor to be a bright image, whi...

[0004] When there is no sunlight interference, the background image is a group of relatively bright images, and the touch object at this time is imaged as a relatively dark data; but when the sun shines on the touch object, the touch object will be illuminated, and at the same time Reflecting strong infrared light into the space, resulting in a bright image of the touched object in the optical sensor, which is difficult to distinguish from the background image, resulting in poor sunlight resistance
