Interactive whiteboard or interactive flat panel?

First, the difference in size. Due to technical and cost constraints, the current interactive flat panel is generally designed to be less than 80 inches. When this size is used in a small classroom, the demonstration effect will be better. Once it is placed in a large classroom or big conference hall, students sitting in the back row It’s hard to see what’s on the screen. Relatively speaking, the electronic whiteboards currently on the market can be made very large, and schools or other educational institutions can choose an appropriate size according to the size of their application environment. This is also the biggest advantage of the interactive electronic whiteboard. Furthermore, the light-emitting principle of the electronic whiteboard and the smart interactive tablet is different. The former is projected by the projector on the whiteboard, relying on the reflection of the whiteboard to allow students to see the content; while the smart tablet uses a self-luminous system, and the light is relatively bright. bright. Therefore, under the same environmental conditions that match the screen size, it is easier to present details with an interactive smart tablet.

Finally, there is the price factor. In general, although electronic whiteboards need to purchase two products, projector and whiteboard, the total price is still lower than that of interactive flat panel. The price of an interactive flat panel of the same size will be higher than that of an interactive whiteboard. However, there is a difference in the service life of some consumables between the two. The test service life of the interactive smart tablet is about 60,000 hours; the service life of the electronic whiteboard and the bulb in the projector is generally about 3,000 hours. However, the current projection technology is also constantly improving, and the life of some projector lamps can reach 30,000 hours. Therefore, only by fully considering various factors can we give full play to the respective advantages of the two and make the best use of them. If it is best to combine the advantages of the two to make it a complementary organism, the same classroom can be flexibly equipped with multiple interactive smart tablets and electronic whiteboards, which can build a more lively teaching scene and achieve better teaching effects.
