Embodiment Construction

[0025] In order to better illustrate the present invention, further description is now made.

[0026] The production method of the optical touch screen, taking the 42-inch finished product as an example, the steps are as follows:

[0027] (1) Prepare a piece of tempered glass with L: 969mm, W: 564mm, H: 4mm, do black silk screen printing with a width of 20mm on the four sides of the glass, and invert the R7mm corners at the four corners of the glass. Among them, the size of the display area of ​​the 42-inch display is 930mm*525mm, so the finished optical touch product has an increase of 20mm on the four sides of the display area, and the extra area of ​​these four sides is used to fix the optical touch device.

[0028] (2) Prepare two 884mm and two 479mm aluminum alloy frame bars. The frame bars have a rectangular cross-section and a hollow structure inside. There are 45mm air-avoiding processing areas at both ends of the frame bars, and the frame bars face the side of the dis...

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 manufacturing method of an optical touch screen. Background technique [0002] As the simplest and mature computer multimedia human-computer interaction device, touch screen has been widely used, mainly in several forms such as resistive film, capacitor, surface acoustic wave and infrared tube. [0003] The basic structure of the infrared touch screen is to install multiple pairs of infrared emitting and receiving tubes in a certain order along the four edges of the display surface in a frame suitable for installation on the edge of the display; these emitting and receiving tubes are arranged along the direction of 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 is installed on an axis; therefore, these axes form a grid structure on the displ...
