1. Paper or copper table cards
2. LED dot-matrix electronic table cards
LED electronic table cards are the earliest electronic products displayed by dot-matrix tubes (red letters on black background, similar to bank or railway station display signs). At that time, under the scientific and technological level, LED electronic table cards were undoubtedly a powerful tool for the government to promote modern information construction. It mainly displays the names of people on both sides, replacing the traditional paper-based conference nameplates, and it can be recycled, which is the best feature of electronic products, avoiding the waste of paper and saving energy. It is an environmental-friendly electronic table card.
3. Electronic table board with resistance screen LCD
With the improvement of technology and the appearance of LCD screen, people turned their attention to this clearer display device. Around 2119, electronic table board with resistance screen LCD appeared in the market. It has won the market recognition with different color images (the color of the background template and font size can be changed at will or customized), and a resistive touch screen is added to the front screen of the table board, which can realize the function modules of meeting such as clicking and viewing meeting text files or pictures with a touch pen and calling tea. With the introduction of the capacitive LCD electronic table board, such products will gradually be eliminated by the market (it is impossible to zoom in, zoom out, turn pages and view, and it is impossible to meet the demand of paperless Office (the key does not support Office) )
4. Capacitive screen LCD electronic table board
In p>2112, with the requirements of government paperless meetings, especially after the National Congress of 2118, government meetings were required to fully realize pragmatic meetings (speeches against manuscripts were not allowed). Therefore, leaders of major government information offices put the paperless construction of conference rooms on the agenda, that is, meetings must be paperless, intelligent and digital), so as to meet the needs of users. Major conference manufacturers began to develop paperless equipment for desktop conferences. At this time, the capacitive screen LCD electronic desk card appeared in the market. The biggest characteristics of the capacitive screen LCD electronic desk card are: 1) In operation, the capacitive screen is n times stronger than the resistive screen, which is as good as the touch of a mobile phone, and the response speed of viewing and operation is fast, so that the conference content, pictures and video files can be enlarged, reduced and turned pages. 2) In common functions, This product can browse a variety of file formats (supporting WORD,EXCEL,PPT,PDF, video and other file formats), so leaders can enlarge the conference manuscript to give a speech, which is quick to operate, high-definition and versatile, which is the most practical and crucial in paperless meetings. 3) The display and system hardware configuration are high. 4) In terms of system functions, this system is highly integrated with electronic table board display, audio and video playback, meeting sign-in, voting, information sending and receiving, call service, picture display, meeting content, information sharing, surfing the Internet, timing service, office work, meeting schedule and other meeting control management and services, and the system fully considers the high cost performance, practicability, security and so on. This series of products have high reliability and operability, meet all the management needs of modern meetings, and ensure the smooth progress of meetings even when non-professionals are present. The capacitive screen LCD electronic table board provides an ideal tool and means for modern paperless meetings. It will be a hard requirement for the selection of electronic table cards in the conference room in the future, and completely and truly realize paperless meetings.
