1. Project background

Nanning Yucai School is one of the key teaching units in Guangxi Autonomous Region. Since 2011, in order to further improve the teaching quality and improve the modern teaching level, the school has specially introduced various multimedia audio-visual teaching facilities. Especially this year, the school increased its investment in teaching funds, further improved and transformed teaching facilities, and used more advanced multimedia interactive teaching to help improve students' interest in learning and teaching quality. As an important presentation device, the projector has also become an indispensable part of the school's multimedia teaching.

2. Solution

Unlike enterprise users, in addition to requiring proper brightness and color reproduction, educated users also pay more attention to the true reproduction of teaching documents and image details. In addition, in terms of installation, heat dissipation, dust prevention, projection distance, etc., education users also have specific needs. As a leading manufacturer in the projector field, Sony has rich experience in products and services in business and education.

After conducting field visits and referring to the multimedia teaching equipment of other brother schools, the school ’s relevant procurement teacher locked the selection scope into three types of telephoto projectors, ordinary short-throw projectors and ultra-short-throw projectors. In the Sony projector store in Nanning Electronic Technology Square, the school teachers conducted a field experience. The excellent presentation effect of the Sony projector left a deep impression on users. After that, the staff of Sony distributor Diling Film and Television Equipment Co., Ltd. cooperated with the school's teacher in charge of equipment purchase to arrange several projectors for field trial evaluation in the school classroom.

Due to the inconvenience of dismounting the brackets of the originally installed TVs in the classroom, the installation distance of the telephoto projector was insufficient. Sony dealers assisted users to compare the ordinary short-throw projector VPL-SX125 and the ultra-short-throw projector VPL-SX535. Based on the classroom projection space and the evaluation of the machine by the school's audio-visual equipment teacher, the Sony VPL-SX535 was finally selected.

The VPL-SX535's ultra-short-throw design (the body only needs to be 27 cm away from the wall when hoisting), you can project without changing the fluorescent lamp position on the classroom blackboard. This point is very in line with the school's "minor changes, big changes" design ideas. At the same time, because the fluorescent lamp is very close to the projector installation, there are many difficulties in installation and projection, and VPL-SX535 provides a hanger that can adjust the projection angle of the projector, and then cooperate with the lens shift function without changing any surrounding The equipment can be installed and put into use, greatly helping the school save labor costs. In addition, the VPL-SX535 has a double-layer filter design, which can prevent dust more efficiently. Even in a dusty public place such as a classroom, the machine can still be well protected.

3. User feedback

After several months of use, SX535 has played an active role in the daily multimedia teaching of Yucai School, bringing more fun to the teaching of teachers and students. The teachers expressed great satisfaction with the excellent projection effect and stable and reliable operation of SX535. The timely and powerful technical guarantee and thoughtful after-sales service of Sony dealers also won the unanimous approval of teachers.
