Introduction: Mencius said: "the wise man makes others clear with his own wisdom"; the main idea is that the wise people usually let themselves have wisdom first, and then make others aware of it. The same is true for a school. Only with advanced teaching equipment and excellent and responsible teachers, can the students who teach have both moral integrity and ability and the same conduct.

Project Profile:

Linzhi vocational and technical school was founded in August 1999. There are 144 staff and nearly 2000 students in the school. It has more than 10 majors, such as tourism service and management, operation and management of high-star hotels, preschool education, automobile operation and maintenance.

Linzhi vocational and technical school

Since the establishment of the school, Nyingchi technical vocational school has gradually improved the quality of education and teaching, and has created a characteristic school running road that accurately connects the supply and demand market, and has cultivated nearly 10000 skilled talents, providing intellectual support and technical support for the rapid development of local economy and society.

Recently, Nyingchi technical vocational school realized that the traditional projector equipment in multimedia classroom is obsolete, and students can't see the platform clearly in class, which leads to teaching reduction and can't meet the needs of modern teaching. After meeting and research, it is decided to introduce more high-definition intelligent large screen display equipment.

After market research, the LCD splicing screen on the market is high-definition with complete functions, which is most suitable for classroom teaching. After several comparisons of domestic LCD splicing screen brands, it is found that huabangying LCD splicing screen has outstanding performance in all aspects, has a good reputation both inside and outside the industry, and has been recognized in terms of product quality and service, so it has launched a close relationship with huabangying Cooperation on large screen project in multimedia classroom.

Conceptual design

In the early stage of the project, huabangying LCD splicing large screen display solution engineer designed a set of 3 * 3 / 55 inch 0.88mm large screen display scheme according to the site data, project budget and display requirements provided by relevant persons in charge of Linzhi technical vocational school;

Features of LCD splicing large screen display scheme in Multimedia Classroom:

The system has the characteristics of high-quality, long-term, long-term, long-term, high-quality, long-term, and high-quality, long-term, and high-quality teaching system.

Diversified display: LCD splicing display has the advantages of high definition, high resolution, good color restoration, etc., and can support the reception of remote massive signals. It integrates multi screen image processing technology and signal switching, and can freely carry out high-end display operation functions such as cross screen, overlay, picture in picture, zoom and expand in the LCD splicing screen Meet the needs of daily teaching activities, such as giving ppt lectures, playing high-definition teaching videos, explaining teaching knowledge points with pictures and texts, so that students can learn more efficiently. Teachers' teaching does not have to be as cumbersome as in the past, and there is no need to face dust filled blackboards, clumsy electronic whiteboards and fuzzy projectors. It can be said that more can be said with one action.

Finally, the 3 * 3 / 55 "0.88mm large screen splicing scheme was affirmed and recognized by the relevant person in charge of Nyingchi technical vocational school. Subsequently, both parties agreed and signed the project contract。

Project installation：

Before the agreed construction period, huabangying sent professional installation engineers together with hby-pj550p-4 (huabangying 55 inch 0.88mm) to Linzhi City, which is known as "the south of Tibet" with beautiful scenery and rich tourism resources, and started to install the splicing screen project of Nyingchi technical vocational school.

Installation site details:

1. The engineer determines that the wall can be loaded and the splicing wall is smooth;

2. The engineer arranges on-site wiring, and separates the weak current line from the strong current line with a wire slot to avoid signal interference;

3. The engineer determines that there is no strong light near the splicing screen and no environmental factors that affect the use of the splicing screen;

4. The engineer confirms that the heat dissipation of the splicing screen is good;

5. The engineer confirms that the power supply system is normal and reaches a three-phase balance;

6. Check whether the splicing unit and peripheral equipment sent and installed by the project are incomplete or damaged;

Project information:

The LCD splicing unit used in this project is HBY-PJ550P-4, Winbond 55-inch 0.88mm LCD splicing screen, the panel type is LG industrial-grade LCD A+ panel, equipped with direct-lit LED backlight with uniform brightness distribution, and the displayed picture is high-definition natural Undistorted, delicate and separable, colorful, saturated and bright without dim light; wide viewing angle, viewing angle up to 178°, more in line with the actual needs of multimedia classrooms, support DVI, HDMI, VGA, BNC, RJ45 and other interfaces, access to signals The source is more abundant.

Project summary:

There is a saying in "Lü Shi Chunqiu": "If you get ten good horses, you don't get a bole; if you get ten good swords, you don't get an Ouye; if you get a thousand miles, you don't get a wise man", and the author thinks this time Linzhi City Technical Vocational School introduced Winbond’s LCD splicing screen as the large-screen display device of the multimedia classroom, and it has also received "Bo Le, Ou Zhizi, and wise man", so that the quality and efficiency of future teaching will be steadily improved, and better teaching will be written Chapter. (Note: Ou Yezi, a native of Yue from the late Spring and Autumn Period to the early Warring States period, the originator of the ancient Chinese sword, and the founder of Longquan Baojian)

Today, the project has been successfully completed with the efforts of Huabangying’s professional installation engineers. After the experience is received, the project has been put into use normally. Huabangying once again thanks Linzhi Technical Vocational School for its trust and support.
