Problems solved by technology

[0004] 1. If the touch accuracy is not enough, there will be a touch dead angle position
[0005] 2. Although it is claimed in the parameters that it can support double-point touch, it is impossible to realize it according to the principle of optical touch screen. Under the condition of dual cameras, if there are two touch points, two ghost points will be generated, which cannot be accurately positioned.
[0006] 3. The touch screen is easy to accumulate dust

Abstract

The invention discloses an optical touch screen display which comprises a mounting frame, tempered glass, reflective strips, CCD cameras and a display. A plurality of mounting grooves are formed on the mounting frame, lifting bases are arranged in the mounting grooves, and grooves are formed at the inner side of the mounting frame. A strip-shaped connecting block is connected to the back of the mounting frame, a plurality of fixing screws are evenly distributed on the connecting block, and sponge adheres to the bottom of the connecting block. The reflective strips are respectively positioned at the four sides of the mounting frame and are higher than the mounting frame, an ash removal layer is arranged under the reflective strips, and a plurality of ash removal holes and small fans are arranged on the ash removal layer. At least four CCD cameras are fixed to the base, the display is located on the back of the mounting frame and is connected with the mounting frame through fixing screws, and the tempered glass is located right in front of the display. The display is convenient to install and operate, and enables the touch precision and the touch point positioning speed to be greatlyimproved.

Description

technical field [0001] The invention relates to a display, in particular to an optical touch screen display. Background technique [0002] One of the advantages of the touch screen is a good way of human-computer interaction, intuitive and simple, even for people who usually have little contact with computers, they can quickly get started. Optical sensors respond quickly to detailed movements and can be used in conference venues, commercial exhibition venues, education and training venues, exhibitions, financial industries, and military industries. [0003] The mainstream touch screens currently on the market all utilize two cameras to capture the position of the finger, but it has the following deficiencies: [0004] 1. If the touch accuracy is not enough, there will be a touch dead angle position. [0005] 2. Although it is claimed in the parameters that it can support dual-point touch, it is impossible to realize it according to the principle of optical touch screen. Un...
