Opportunities for the development of multimedia teaching LED electronic screens

Opportunities for the development of LED electronic screens for multimedia teaching. Blackboard + chalk is the most familiar thing in our school days. How useful can LED electronic screens be in classrooms? Smart cities are now being implemented, and LED electronic screens also bring intelligence to classrooms. Teaching, vivid subject matter cases, interactive man-machine collision, not only save time but also cultivate students' interest, the future popularization trend of LED electronic screen teaching. With the continuous advancement of LED electronic screen technology, continuous improvement of technological level, and continuous reduction of price, it is also a necessary condition for it to replace projectors. The area of ​​LED electronic screens for teaching display is generally within 2~3 square meters. United Huiye Technology is A school in Shiyan, Shenzhen recommends indoor full-color P3 LED electronic screens, and provides free life-long maintenance, free life-long software upgrades, free replacement within the warranty period, and free door-to-door service. In traditional teaching, teachers mainly use their own language and body language to explain teaching, and writing time takes up a lot of teaching time, making teaching usually very slow; multimedia teaching uses multimedia computers to comprehensively process and control symbols, language, Various media information such as text, sound, graphics, images, video, etc., organically combine various elements of multimedia according to the teaching requirements and display them on the LED electronic screen. The human-computer interaction operation among them can complete the teaching or training process.

Now, mentioning multimedia teaching has become a very common thing. It puts an end to chalk and blackboard eraser, and makes boring teaching vivid. By using blackboard writing, textbooks, charts, pictures and other conventional methods for multimedia teaching, the whole teaching The process is displayed on a large LED electronic screen, and finally completely get rid of the teaching method of blackboard and chalk. Due to the inherent limitations of the projector, frequent maintenance, frequent dust removal, and short service life of the lens and bulb, it needs to be replaced continuously. If not replaced, the brightness will attenuate too much, which will affect the quality of teaching. . In response to the prominent problems of multimedia teaching projectors, we will promote LED electronic screens instead of projectors. LED electronic screens have their inherent advantages, customized installation, low failure rate, less maintenance and convenient maintenance, clear picture quality, adjustable brightness, It can be used for teaching under natural light.

Multimedia classrooms are an integral part of modern digital campus construction. The general multimedia hardware equipment consists of computers, consoles, projectors, audio and related external connection equipment to help teachers improve teaching quality and teaching efficiency. Advantages of multimedia teaching: ① Intuitive, able to break through the limitations of vision, observe objects from multiple angles, and can highlight key points, which is helpful for the understanding of concepts and mastery of methods; , attention and interest; ③Dynamic, which is conducive to reflecting concepts and processes, and can effectively break through teaching difficulties; ④Interactive, students have more participation, learning is more active, and by creating a reflective environment, it is beneficial to students Form a new cognitive structure; ⑤The expansion of ordinary experiments is realized through multimedia experiments, and through the reproduction and simulation of real situations, students' exploration and creativity are cultivated; ⑥Repeatability is conducive to breaking through the difficulties and difficulties in teaching. Overcoming forgetting; ⑦ Pertinence, making it possible to teach students at different levels. ⑧The large amount of information and large capacity of the LED electronic screen saves space and time and improves teaching efficiency.
