A method of manufacturing an optical touch screen

Abstract

The invention discloses an optical touch screen manufacturing method, and relates to the technical field of optoelectronic sensing. The optical touch screen manufacturing method comprises the following steps that (1) black silk screens are added at four edges of a piece of rectangular tempered glass, wherein a region surrounded by the black silk screens is a display region; (2) aluminum alloy frame strips are placed at four edges of the tempered glass; (3) a main CCM corner block, a first sub CCM corner block, a second sub CCM corner block and a virtual CCM corner block are placed in an avoidance processing region, and the main CCM corner block, the first sub CCM corner block and the second sub CCM corner block are respectively placed at the right upper corner part, the left upper corner part and the right lower corner part outside the display region; (4) the first sub CCM corner block and the second sub CCM corner block respectively pass through the aluminum alloy frame strips through four-core data wires and are connected with the main CCM corner block. The optical touch screen manufacturing method has the advantages that CCM modules and aluminum alloy frame bodies with high reflection functions are adopted, and the CCM lighting standard can be regulated, so products are firmer, more stable and more attractive, and meanwhile, the problem of outdoor sunlight interference is solved.

Description

Technical field [0001] The invention relates to the technical field of photoelectric sensing, in particular to a method for manufacturing an optical touch screen. Background technique [0002] As the most simple and mature computer multimedia human-computer interaction device, touch screens have been widely used, mainly in several forms such as resistive film, capacitor, surface acoustic wave and infrared pair tube. [0003] The basic structure of the infrared touch screen is in a frame suitable for installation on the edge of the display. A plurality of infrared transmitting and receiving tubes are installed in a certain order along the four edges of the display surface of the display; these transmitting and receiving pairs are in the direction along the edge of the display surface Arranged to form a mutually perpendicular transmitting and receiving array, in which each pair of transmitting and receiving tubes are installed on an axis; therefore, these axes form a grid structure o...
