Problems solved by technology

The traditional piezoresistive touch screen needs to exert a certain force on the screen to achieve touch control. Since the force of each person is inconsistent, there will be insufficient sensitivity in the control; the capacitive touch screen is more sensitive than the traditional piezoresistive sensor. Widely used in mainstream touch products
[0003] The above two different touch screen implementation principles have the following common points: the sensor is located directly below the screen, and the size of the screen requires a large sensor array, which is limited in terms of cost and experience in large-screen applications
At the same time, it requires the user to have close contact with the screen, which is not conducive to flexible application in specific occasions
For example, in terms of teaching, how to realize the easy control of the pointer on the large-screen projection screen will be a challenge to the traditional touch screen control mechanism

Embodiment Construction

[0015] see figure 1 As shown, the touch screen is provided with a touch positioning frame around the display screen, which includes: a rectangular display screen 100 , a touch positioning frame 101 and a computer host 102 . In order to ensure the authenticity of the touch, the touch positioning frame 101 matches the size of the border of the display screen 100 , and the touch positioning frame 101 is fixed on the periphery of the display screen 100 .

[0016] Two-way communication is realized between the touch positioning frame 101 and the computer host 102, and the communication method can be wired communication or wireless communication. At the same time, if a data processing and communication module is set in the touch positioning frame 101, the positioning algorithm can be implemented in the computer host 102, or can be implemented in the data processing and communication module; the data processing and communication module can be directly The processed positioning positi...

Abstract

The invention discloses a touch screen. The touch screen comprises a rectangular display screen, a rectangular touch positioning frame and a computer mainframe. A horizontal projection of the touch positioning frame to the display screen is that the display screen is positioned in the touch positioning frame, namely the touch positioning frame is positioned around the display screen. A laser emitter array is arranged in each of two adjacent borders of the touch positioning frame to form laser emission borders; a laser receiver array is arranged in each of the other two adjacent borders of the touch positioning frame to form laser receiving frames. The laser emission borders and the laser receiving borders are opposite pairwise, the touch positioning borders are in two-way communication with the computer mainframe to transmit positioning position information or original data acquired by the touch positioning frame. The touch screen has the advantages that stability touch control on the large screen can be realized, actual touch of the display screen is not needed, and touch control can be realized flexibly.

Description

technical field [0001] The invention relates to a touch screen. Background technique [0002] With the popularization of touch screen technology in the application of handheld electronic devices, the requirement for intuitive control is also getting higher and higher. The smart phones that people can see now have all developed towards the touch screen, including tablet computers, e-books and so on. The traditional piezoresistive touch screen needs to exert a certain force on the screen to achieve touch control. Since the force of each person is inconsistent, there will be insufficient sensitivity in the control; the capacitive touch screen is more sensitive than the traditional piezoresistive sensor. It has been widely used in mainstream touch products. [0003] The above two different touch screen implementation principles have the following points in common: the sensor is directly below the screen, and the size of the screen requires a large sensor array, which is limite...
