Medical screen query application system uses more new technologies and new ways. Hardware, medical screen for SAW screen, has the advantages of scratch resistance, small reflection, fast response time and long service life. The shape of the product is more streamlined, with a certain affinity and sense of the times. In terms of software, the software is full of modern multimedia technology, while Flash is the overall design. Query system interface, graphics, beautiful background music, dynamic screen effects, text, pictures, video and other data are stored centrally.

Medical screen system generally includes medical screen controller (card) and touch detection device. The main function of the medical screen controller (card) is to receive touch information from the touch point detection device. And can be replaced by contact coordinates, contact coordinates can receive commands from the CPU and execute while passing to the CPU; touch detection is generally installed on the front of the medical screen, mainly to detect the location of the user's touch point at the moment of action, and transmitted to the medical screen controller card. Medical screen is flexible, can design stronger functional modules, scalable, can meet more complex east-west process manufacturing projects, and can even communicate directly with PLC through the network system, which greatly facilitates the control, processing and transmission of data, and can reduce the amount of maintenance.

In real life, our standard of living has improved significantly and there are many electronic products around us. The anti-interference problem of medical screen is now a great headache for medical screen manufacturers. The problem of anti-interference of medical screen is one of the performance requirements of medical screen. If the anti-interference ability is weak, it will affect the effect of the medical screen of the switchboard, such as touch is not sensitive, inaccurate, and greatly affected by the outside world.

First, we must understand the structure and principle of medical screen, and then find out the cause of medical screen anti-interference, generally affected by its: medical screen anti-interference problems are: jumping screen, touch inaccurate, or complete failure. Then first determine whether there are external factors, such as untimely power supply, weak signal, weak antenna signal, etc., these are common, just check whether the above phenomenon and adjust it.

Then, in order to solve the anti-interference problem in the medical screen design, the following adjustments shall be made: first, add virtual wiring in the blank area of the medical screen panel, i.e., fill the wiring outside the display area, and connect the added virtual wiring to each other to form a virtual circuit; second, the virtual circuit is connected to the ground part of the touch chip to form a shielded circuit. This design eliminates the interference of temperature, humidity, ambient electric field, reflection and other factors to the medical screen with low cost and high efficiency.
