LCD splicing screenScheme introduction

The application of flat panel display devices in the education market has a long history. With the guidance of the national education policy and the increase of the investment of the education department, the LCD splicing screen is more widely used in the electronic education classroom, the ladder classroom, the conference room, the academic lecture hall, the multimedia classroom and the invigilation system. Under the guidance of the national policy of promoting education with information technology, colleges and universities, primary and secondary schools have joined the wave of computer transformation and construction.

As the best device for large screen display,LCD splicingIt has been widely promoted and applied in this process. According to market statistics, the current education market is a field where plasma and liquid crystal products are widely used, and it is also the most promising field.

In applications, LCD splicing can be used as a display alone, or it can be spliced into a large screen. According to the user's needs, it can realize the function of dividing the screen into single screen or multi-screen display. LCD splicing has the following advantages: First, since the LCD itself is the longest used display device, the service life of LCD splicing has reachedMore than 50000 hours, and the maintenance cost is also quite low. Secondly, the LCD splicing angle of view is quite large, which has reached about 178 degrees, achieving the effect of absolute angle of view. Thirdly, the resolution of LCD splicing is also quite high, and the picture is bright. Finally, the LCD splicing is ultra-thin and lightweight, with long fault-free time, low total power consumption and low heat generation.

Solution

On the one hand, education procurement funds are relatively tight, and users in education industry are more sensitive to product prices than users in other industries; On the other hand, different from other products, according to the characteristics of complex use environment and long use time of educational users, the requirements for after-sales service are relatively high. When choosing projectors, school users begin to consider the after-sales service capabilities of manufacturers or dealers more.

Faced with the technical indicators, parameters and various brands of large-screen LCD splicing, schools generally have their own principles in selecting products: first, select the brightness indicators suitable for the current basic teaching environment, and select the appropriate image resolution to meet the teaching needs as the scale, while realistic color restoration and high contrast are also very important in teaching. It helps students to clearly distinguish the details of the picture, truly understand and understand the teaching content. Secondly, when selecting the splicing screen for teaching, the uniformity of its brightness and color is also valued.

In fact, for the education industry, the performance and parameter indicators of the products provided by major manufacturers are basically not too different. The key factor for a mosaic screen brand to occupy a place in the education industry is in addition to the product performance, which also means to have a detailed and in-depth analysis and research on the actual application needs of users, so as to directly understand what products users need most, What specific services can the product provide for them. In a word, practicality is the absolute principle, which is the most suitable in the education industry.

So what are the advantages of the current plasma splicing screen and LCD splicing screen in terms of performance and application? In terms of display performance, the ultra-high resolution, brightness and dynamic contrast of the flat panel TV can make the flat panel TV reflect gorgeous and clear images in any environment. Its complete multimedia interface can connect all kinds of teaching equipment, and can completely meet all kinds of applications in teaching. In terms of functions, picture-in-picture, network control, audio output and other features are tailored to the actual application needs of educational users.

Projectors are also widely used in the education industry, butSplicing screenCompared with projection in practical application, it feels a little overshadowed. First of all, splicing the screen has an absolute advantage in brightness. The projector is a projection device used to enlarge and display the image, as its name implies. The external light has a very obvious impact on the display effect of the projection. Therefore, the projection device must be used in a dark place. In actual teaching, it is also very important not only for teachers to speak, but also for students to listen and listen to notes. Obviously, the place where the projector is used is not suitable for notes, The splicing screen does not have this problem. Its ultra-high brightness and resolution can display clear pictures in any place.
