Application of LED video wall in education industry

The application of flat-panel TVs in the education market has a long history. Flat-panel TVs have begun to appear in major public places, such as computer classrooms, conference rooms, and other venues for activities, learning, and entertainment. Under the guidance of the country's general policy of driving the modernization of education with informatization, various colleges and universities, elementary and middle schools have carried out the construction and transformation of computer classrooms and multimedia classrooms one after another.

As the best device for large-screen display, flat-panel TVs have been widely used in this process. It can be said that the education industry is the most widely used field of plasma and liquid crystal products, and it is also the field with the most potential for development. As the application of flat-panel TVs in education becomes more and more mature, users are becoming more and more cautious in application selection and procurement. In addition, the different levels of economic development across the country also determine the difference in educational funding. Therefore, education users are There are also different application requirements for purchased products.

On the one hand, education procurement funds are relatively tight, and users in the education industry are more sensitive to product prices than users in other industries; on the other hand, because they are different from other products, they require after-sales service based on the complex use environment and long use time of education users. Relatively high. When school users choose projectors, they start to consider the after-sales service capabilities of manufacturers or distributors more.

Facing the technical indicators, parameters, and various brands of flat-panel TVs, schools generally have their own principles in choosing products: first select the brightness indicators suitable for the current basic teaching environment, and choose the appropriate image resolution for the scale to meet the teaching needs. Realistic color reproduction and high contrast are also very important in teaching. It helps students to clearly distinguish the nuances of the picture, and to truly understand and understand the teaching content. Secondly, when choosing a flat-screen TV for teaching, the uniformity of its brightness and color is also valued.

In fact, as far as the education industry is concerned, the performance and parameter indicators of the products provided by major manufacturers are basically not much different. If a flat-panel TV brand wants to have a place in the education industry, the most critical factor is that in addition to product performance, it is also An analogy requires meticulous and in-depth analysis and research on the actual application needs of users, so as to be able to directly understand what products users most need, and what specific services they need products to provide. In a word, practicality is the last word, and it is the most suitable in the education industry.

So what are the advantages of current plasma and LCD TVs in terms of performance and applications? In terms of display performance, the ultra-high resolution brightness and dynamic contrast of flat-panel TVs can make flat-panel TVs reflect brilliant and clear images in any environment. Its complete multimedia interface can be connected to a variety of different teaching equipment, which can fully meet various applications in teaching. In terms of functions, features such as picture-in-picture, network control, audio output, etc., seem to be tailored to the actual application needs of educated users.

The application of projectors in the education industry is also quite extensive, but compared with flat-panel TVs, the actual application of projectors feels a bit dwarfed. First of all, flat-panel TVs have an absolute advantage in terms of brightness. As the name suggests, a projector is a projection device used to magnify the displayed image. The external light has a very obvious impact on the display effect of the projection, so the projection equipment must be in a relatively high In a dark place, in actual teaching, it is not only the teacher’s lecture, but also the students’ listening and taking notes. Obviously the place where the projector is used is not suitable for taking notes. This problem does not exist in the flat-panel TV. Its super high brightness and The resolution can display a clear picture in any place.

Secondly, the 4000-hour service life of the general projector lamp is relatively short. Frequent replacement will affect normal teaching and the cost will increase. The service life of plasma and LCD TVs is generally 60,000 hours, which is 8 hours per day. That is, it can be used normally for more than fifteen years. According to industry forecasts, flat-panel TVs will replace projection and become the mainstream of display devices in the education industry.

When selecting teaching display equipment, in addition to factors such as price and performance, it is also affected by factors such as the use environment and the user’s own level. This requires product manufacturers to have complete after-sales services, especially in terms of hardware maintenance. So it is.

Major flat-panel TV manufacturers such as Panasonic, Samsung, and Sharp not only implement a nationwide warranty, but also strictly implement the national three-year warranty for flat-panel TVs. The after-sales service response speed is also faster, allowing users to truly feel "user-oriented "The intimate service. For users in the education industry, these thoughtful service measures are exactly what they most practically need.

According to the analysis of industry veterans, no matter which market segment, as customers should have a rational understanding of display equipment, cost pressure and service needs, their choice of display solutions will shift from pure technical indicators to practical applications. The effect of demand.

Moreover, from being highly sensitive to price, it will also be transformed into a comprehensive consideration of performance, price and service. With the homogenization of technology, costs and prices, services and solutions will play a greater role. It seems that "practicality is the last word", this core concept is at least the most effective magic weapon to win users in the field of education.
