Description

Technical Field

[0001] The utility model relates to a surface acoustic wave touch technology and an artificial intelligence screen, and in particular to a surface acoustic wave intelligent screen. Background Art

[0002] In the current fast-developing modern society, the demand for human-computer interaction is increasing day by day, showing an explosive development. Whether in household appliances, cars, factory machines, etc., there are fewer and fewer devices without human-computer interaction, and the proportion of devices with human-computer interaction with touch function is increasing. But at the same time, new technical bottlenecks have also emerged. The size of the touch screen is getting larger and larger, and the recognition accuracy and anti-interference requirements are also getting higher and higher. This is a very high challenge for the existing capacitive touch technology. The challenge lies in the need to support both multi-point fast capacitive touch recognition and anti-interference. The two requirements of the challenge are contradictory in themselves, so only a compromise can be chosen. Secondly, the content of human-computer interaction is becoming more and more complex, and the development time reserved for designers is getting less and less. Whether to use the existing operating system to implement or to implement the human-computer interaction function by yourself, it takes a lot of time to develop the human-computer interaction logic and process. Therefore, the past human-computer interaction products not only have inherent disadvantages in product functions for end customers, but also have many problems in product development. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a surface acoustic wave intelligent screen with high touch accuracy, fast response, strong anti-interference ability, improved light transmittance of the liquid crystal screen and long service life.

[0004] The technical solution of the utility model to solve the above technical problems is as follows: a surface acoustic wave smart screen includes a surface acoustic wave touch screen module, a liquid crystal screen module, and a smart screen circuit module. The surface acoustic wave touch screen module is structurally installed above the liquid crystal screen module; the smart screen circuit module is installed below the liquid crystal screen module; that is, the structural order from top to bottom is the surface acoustic wave touch screen module, the liquid crystal screen module, and the smart screen circuit module.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, the function of the surface acoustic wave touch screen module is to identify touch actions and transmit touch coordinates; further, the surface acoustic wave touch screen module is only in structural contact with the liquid crystal screen module, and has no electrical contact; further, the surface acoustic wave touch screen module is connected to the smart screen circuit module through a communication interface; further, the surface acoustic wave touch screen module and the smart screen circuit module include communication and power supply through the communication interface, completing the electrical connection relationship.

[0007] Furthermore, the substrate of the surface acoustic wave touch screen module is glass, so explosion-proof glass, glass with filter, etc. can be used in practical applications.

[0008] Furthermore, the surface acoustic wave touch screen module is based on the principle of transmitting and receiving sound waves, so there is no physical interference intersection with external electrical signals, and thus the anti-interference performance is high.

[0009] Furthermore, the function of the LCD screen module is to transmit human-computer interaction information through a color picture; further, the LCD screen module is connected to the smart screen circuit module through a driving interface, and the smart screen circuit module completes the image signal refresh function of the LCD screen module through the driving interface.

[0010] Furthermore, the smart screen circuit module is an electronic circuit with multiple smart chips, which completes the communication interaction of the surface acoustic wave touch screen, the image display of the LCD screen module, the intelligent calculation of human-computer interaction and other functions through the electronic circuit and software algorithm.

[0011] Further, the smart screen circuit module includes three parts: a T5L processor, a power supply circuit, and a user interface; further, the T5L processor is the main control chip of the smart screen, which realizes communication with the surface acoustic wave touch screen module; realizes driving the liquid crystal screen module; and realizes communication with external whole machine system equipment through the user interface; further, the power supply circuit realizes the power conversion function of each electrical module of the smart screen; further, the power supply circuit realizes the conversion of the primary power supply of the user interface to the secondary power supply available for the smart screen; further, the power supply circuit realizes the conversion through the secondary power supply to the tertiary power supply required for the surface acoustic wave touch screen; further, the power supply circuit realizes the conversion through the secondary power supply to the tertiary power supply required for the liquid crystal screen module; further, the power supply circuit realizes the conversion of the tertiary power supply required in the smart screen circuit module through the secondary power supply; further, the user interface realizes the communication of human-computer interaction results between the smart screen and the main control device in the whole machine system; further, the communication end of the user interface is the T5L processor and the main control in the system.

[0012] The beneficial effect of taking the above steps is that the complete structure and function of the human-computer interaction smart screen are realized through the combination of the surface wave touch screen module, the liquid crystal screen module and the smart screen circuit module.
