How much do you know about the past and present of the blackboard?






人们交流无非有两种方式，一是口语交流，二是书面交流。而有一种东西伴随着我们从小长大，一直影响和改变着我们的交流方式，它巧妙而生动地结合了口语和书面两种交流方式，让我们既能看到又能听到，所以从古到今的教学、培训、演讲、会议、宣传等这些需要大量交流的场所，都离不开一个叫;黑板;的工具。在文字发明以前，人们发现木炭可以作画，在欧洲的一些古代岩洞里可以发现古代的一些壁画，画着这些壁画的岩壁从传统意义上讲已经可以称为黑板。但是随着时代的发展，黑板;这个名词也在不断地丰富和完善她自身的内涵，不断地强化和提升她自身的功能。我们中国黑板批发网通过对行业的仔细研究和全局的深入酝酿，提炼总结出了黑板发展演变史上的五个重要时代：代是写字类黑板：选用的是生产生活中常见的材料制作而成，主要用普通笔支在表面书写文字为主，如木制黑板、水泥黑板、玻璃黑板和金属黑板等。
There are two ways for people to communicate, one is oral communication, and the other is written communication. And there is something that accompanies us as we grow up, constantly influencing and changing our way of communication. It cleverly and vividly combines oral and written communication methods, allowing us to both see and hear. Therefore, from ancient times to the present, teaching, training, speeches, meetings, propaganda, and other places that require a lot of communication cannot be separated from one name; Blackboard; The tool. Before the invention of writing, people discovered that charcoal could be used for painting. In some ancient caves in Europe, ancient murals could be found, and the rock walls depicting these murals were traditionally referred to as blackboards. But with the development of the times, the blackboard; This term is also constantly enriching and improving its own connotation, constantly strengthening and enhancing its own functions. Our China Blackboard Wholesale Network has carefully studied the industry and deeply brewed the overall situation, extracting and summarizing five important eras in the development and evolution history of blackboards: Daishi Writing Blackboards: Made from common materials in production and life, mainly using ordinary pens to write on the surface, such as wooden blackboards, cement blackboards, glass blackboards, and metal blackboards.






第二代是无尘类黑板：为了适应专业书写和安全环保的要求，逐渐产生了制的书写面板材料，既能好写好擦又没有粉尘污染，如普通白板、专业书写级白板、绒布告示板、表格画线板和环保书写膜等。第三代是影音类黑板：借助现代科学技术的发展，别是投影成像类的产品出现，黑板也从简单的文字书写演变到具有图片显现的功能，并且可以整合音响话筒之类配套产品，图文结合声情并茂成为黑板发展史上一次质的飞跃，比如我们现在常见的亚光投影白板、电动投影白板、投影幕布、复印式电子白板、电子显示屏、荧光黑板等。第四代是交互类黑板：图文结合的黑板往往按着事先设置好的图文很被动的显示给听众，这又恰恰失去了黑板与身俱来应该有的随心书写自由演示的优点。直到近几年来电脑技术的不断应用和广泛普及，人们终于发明出了一种划时代的革命性产品。
The second generation is dust-free blackboard: In order to meet the requirements of professional writing and safety and environmental protection, a series of writing panel materials have gradually emerged, which can be easily written and wiped without dust pollution, such as ordinary whiteboards, professional writing grade whiteboards, velvet billboards, table drawing boards, and environmentally friendly writing films. The third generation is audiovisual blackboards: With the development of modern science and technology, especially in the field of projection imaging products, blackboards have evolved from simple text writing to having the function of displaying images. They can also integrate supporting products such as sound microphones. The combination of graphics and text has become a qualitative leap in the development history of blackboards, such as the commonly seen matte projection whiteboard, electric projection whiteboard, projection screen, photocopy electronic whiteboard, electronic display screen, fluorescent blackboard, etc. The fourth generation is interactive chalkboards: chalkboards that combine graphics and text often passively display them to the audience according to pre-set graphics and text, which precisely loses the inherent advantage of free writing and demonstration that blackboards should have. Until the continuous application and widespread popularity of computer technology in recent years, people have finally invented a revolutionary product that is epoch-making.






交互式电子白板，实现了黑板和电脑互通互联，让浩瀚无穷的互联网可以无限地展现在黑板这方寸之间，任由我们随意点画畅游天地，如压感式电子白板、超声波电子白板、电磁式电子白板、红外式电子白板、激光式电子白板等。第五代是显像类黑板：这一代产品主要集中解决了交互式电子白板需要各种外设硬件来配套使用，把成像显像技术和互联网络技术全部集中在了黑板自身身上，从此黑板包容无限其乐无穷，可以淋漓尽致地为人们交流提供直接简单的书写服务，同时又可以声色俱全地提供高效丰富的图像服务，如电视型黑板、电脑型黑板、手机型黑板、电纸书、数字标牌等。你读到这里是不是有点惊奇，甚至想大加感叹一下，一块小小的黑板居然有这么多无人知晓的灿烂历史，一块小小的黑板居然为人类的交流发挥着不可替代的作用！
The interactive electronic whiteboard has realized the interconnection between the blackboard and the computer, so that the vast and endless Internet can be displayed between the blackboard, allowing us to draw freely, such as pressure sensitive electronic whiteboard, ultrasonic electronic whiteboard, electromagnetic electronic whiteboard, red external electronic whiteboard, laser electronic whiteboard, etc. The fifth generation is the imaging blackboard: this generation of products mainly focuses on solving the problem that the interactive electronic whiteboard needs various peripheral hardware to support the use of, and the imaging imaging technology and Internet technology are all concentrated on the blackboard itself. Since then, the blackboard has unlimited fun, which can provide direct and simple writing services for people's communication incisively, and can also provide efficient and rich image services in sound and color, such as TV blackboard, computer blackboard, mobile blackboard, e-paper book, digital signage, etc. Are you a bit surprised to read this, even wanting to exclaim even more that a small blackboard has so many brilliant histories that no one knows? A small blackboard plays an irreplaceable role in human communication!
