Educational system LCD touch interactive teaching plan Industry application With the rapid development of computer networks and display devices, the LCD touch interactive display has been widely used in education and teaching due to its advantages of both graphics and text, and easy to use. With this system, we only need to touch the large screen display with our fingers The icon or text or direct handwriting can make the teaching content difficult, and abstract into concrete, thereby enhancing the interactivity of teaching. Application Analysis 1. Can be trained or taught: the traditional teaching methods are mostly monotonous blackboard handwriting teaching methods, students who accept obscure and difficult to understand content will be greatly discounted, or they will use projection equipment to assist teaching, although this effect is great Improvement, but more troublesome; and the LCD touch interactive teaching can easily solve all these problems, without the need for other auxiliary equipment, allowing all the teaching content to be displayed in a graphic and graphic manner through the LCD large-screen display terminal. In front, save time and effort; 2. Course content handwriting presentation, drawing: In addition to solving traditional teaching content, the LCD touch interactive system also supports course content handwriting presentation, drawing and other functions. It is really powerful. Single teaching can make abstract teaching content vivid. It is easy to be accepted by every student, and can also be used for professional comics and other demonstrations. Function introduction Tonghui Jiashi touch products can provide full-size specifications. By installing infrared or CCD touch devices, it can realize touch query and handwriting annotation functions for various displays such as liquid crystal, plasma, and projection. It can directly comment on the screen, and can be used as a POS vending machine, electronic whiteboard, graphic commentator, etc. It can be widely used in: education and teaching, video conferencing, live TV, multimedia inquiries, self-service retail, exhibition promotion, electronic maps, etc. Product Features The working principle of the infrared touch screen: the infrared receiving tube and the infrared emitting tube are covered around the touch screen. These infrared tubes are arranged in a one-to-one correspondence on the surface of the touch screen to form an optical network composed of infrared rays. When there are objects (finger , Wearing gloves or any touching objects) When entering the infrared light network to block the infrared transmission and reception of a certain place, the strength of the infrared received by the receiving tube in both horizontal and vertical directions at this point will change, and the device can understand the infrared receiving situation The change can tell where the touch was made. The working principle of the CCD touch screen: Scan and collect the image of the touch area through the CCD installed on the surface of the touch screen, identify the contact point through image processing, and finally accurately calculate the coordinates of the contact point by the triangle positioning method, and the system responds to the coordinates Realize touch. main feature Feature 1: High-strength tempered glass can be installed, which is wear-resistant, waterproof, dust-proof, easy to maintain, long-life, economical, and does not affect the appearance and display effect of the display; Feature 2: The structure design is flexible and adaptable, suitable for LCD, plasma, projector, etc. The screen size ratio of length to width is not limited to large customers to achieve 250 inches. Feature 3: High sensitivity, good stability, anti-light interference, good explosion-proof performance, can be touched by any object, completely enclosed and maintenance-free, suitable for harsh environments; technical hesitation in response speed and touch accuracy, supports multi-touch and double Writing, it can not only shrink and enlarge the page freely, push any object in the picture, but even adjust the image at will. The management software developed in conjunction with the touch screen has a back-end database to realize specific functions such as local and remote data transfer, data statistics, query, and report output.
