Digital display boards, also known as teaching touch all-in-one machine, is an emerging technology product that integrates multiple functions of TV, computer, multimedia audio, whiteboard, screen, and Internet service. It is being applied to all walks of life more and more. Many consumers are faced with a variety of brands and have no idea where to start. So how to correctly buy a teaching touch all-in-one machine, and what points should be paid attention to when buying a teaching touch all-in-one machine, let's learn about it today.
1. LCD screen
The most valuable hardware of a interactive digital board is a high-quality LCD screen. To put it bluntly, the most valuable part of the all-in-one machine is the LCD screen. Since the quality of the LCD screen directly affects the whole machine display effect and user experience of the teaching touch all-in-one machine, a good teaching touch all-in-one machine must use the highest specification LCD screen as the core hardware of the whole machine. Taking Guangzhou Sosu's teaching touch all-in-one machine as an example, it uses an industry A-standard industrial LCD screen and adds an outer layer of anti-collision and anti-glare tempered glass to increase the safety of the LCD screen, and at the same time add anti-glare function to make the display more outstanding.
2. Touch technology
Current touch technologies include three commonly used types: resistive touch screens, capacitive touch screens, and infrared touch screens. Because capacitive and resistive screens cannot be made too large, infrared touch screens can be made small or large, and have high touch sensitivity and accuracy, are easy to maintain, and have a long service life. The performance of touch technology must meet the following points: number of recognition points: ten-point touch, recognition resolution: 32768*32768, sensing object 6mm, response time: 3-12ms, positioning accuracy: ±2mm, touch durability: 60 million touches. When purchasing, you must pay attention to distinguish between infrared multi-touch and fake multi-touch. It would be better to find a professional manufacturer of infrared digital board for teaching to learn more.
3. Host performance
The host performance of kindergarten teaching touch all-in-one machine is not much different from that of general computers. It is basically composed of several main modules such as motherboard, CPU, memory, hard disk, wireless network card, etc. Customers should choose the one-piece machine suitable for themselves according to the frequency, method, environment, and teaching materials of the interactive smart board they purchase. Because taking CPU as an example, the price and performance of Intel and AMD are different. The price difference between Intel I3 and I5 is large, and the performance is even more different. It is best to buy directly from the manufacturer. They have advantages in hardware technology and personalized customization solutions, and will recommend customers to buy suitable hosts to avoid wasting money and causing unnecessary performance waste.
4. Functional application
The kindergarten teaching touch all-in-one machine integrates the functions of TV, computer and display, and replaces the traditional mouse and keyboard with ten-point touch operation, which can basically achieve the functions of the combination of computer and projector. The teaching touch all-in-one machine can realize more functions with different touch software. It can be applied to school teaching, conference training, information query and other scenes without any problems. The teaching touch all-in-one machine still has many functions. It is recommended to go to the official website of the manufacturer of the teaching touch all-in-one machine to check the products and learn about the functions of the teaching touch all-in-one machine in detail before purchasing.
5. Brand price
The price of the kindergarten teaching touch all-in-one machine is determined by the size of the display screen and the configuration of the OPS computer box. Different sizes and computer box configurations have a relatively large impact on the price, and the difference is from thousands to tens of thousands. Therefore, it is recommended that customers must contact professional manufacturers when purchasing teaching touch all-in-one machines for consultation. According to the environment you use, you can be equipped with a teaching touch all-in-one machine suitable for you, so that you can spend less money and make the most professional choice. Multi-touch technology combined with the interactive electronic whiteboard software built into the teaching all-in-one machine can directly realize powerful interactive teaching and demonstration functions such as writing, erasing, marking (text or line marking, size and angle marking), drawing, object editing, format saving, dragging, enlarging, curtain pulling, spotlight, screen capture, picture saving, screen recording and playback, handwriting recognition, keyboard input, text input, image and sound on the display screen, no longer needing traditional blackboards and chalk and colored pens.
