Google EDLA in schools: Why is it crucial?

Faced with the challenge of equipping an educational facility with modern multimedia equipment, school directors and governing bodies face a key dilemma. Choosing the right technological solution is of fundamental importance for the quality of classes conducted, the comfort of teachers' work, and the effectiveness of knowledge acquisition by students. The market offers two main solutions: a modern interactive display and a classic set consisting of an interactive whiteboard and an ultra-short-throw projector. Although both devices serve for digital interaction, they differ diametrically in technological, financial, and utility terms.

Image quality, brightness, and readability in daylight

The primary difference determining comfort of work in the classroom is the way the image is generated and displayed. An interactive display acts as a large-format screen with 4K UHD resolution, emitting its own light. Thanks to this, the image is crystal clear, expressive, and saturated with colors, and lessons can be conducted without the need to pull down blinds or shutters on sunny days. In turn, an interactive whiteboard with a projector relies on reflecting the light of the projector lamp. This requires ideal room blackout, because in natural sunlight the image becomes faded and contrast drops drastically, which negatively affects the eyesight of students sitting in the back rows.

The problem of shadows, reflections, and ergonomic comfort

Working in front of a traditional whiteboard with a projector is associated with the burdensome problem of shadows. A teacher or student standing by the board blocks part of the displayed content with their body, and the light of the projector lamp often glares in their eyes. In the case of an interactive display, this problem disappears completely. The user can stand directly next to the screen without casting any shadow. Additionally, modern displays have matrices covered with special anti-reflective glass, which eliminates reflections from ceiling lamp light.

Operating costs, durability, and reliability 

When analyzing the total cost of ownership of the equipment, one must consider not only the purchase price, but also expenses over a perspective of several years. Projector sets generate hidden operating costs – projector lamps undergo natural wear and tear and require costly replacement every few years, and air filters must be cleaned regularly. Projectors are also prone to touch calibration drift upon stronger impacts against the wall. An interactive display is a fully maintenance-free device, with a matrix lifespan estimated at over 50,000 hours of continuous operation. Touch is permanently integrated into the panel, making calibration unnecessary.

Government programs and matching modern standards

Implementing purchases under programs schools are increasingly abandoning outdated projection technologies in favor of displays. Displays offer a built-in Android system, access to an educational app store, and software packages for creating interactive lessons without the need to connect an external computer. Tempered glass with a 7H hardness ensures resistance to mechanical damage, which is of key importance in school conditions.

The choice of an interactive display constitutes a forward-looking investment that completely eliminates problems related to servicing, ensures excellent visibility at any time of day, and guarantees high comfort of didactic work.

Frequently asked questions (FAQ) - We answer questions from teachers and principals

Does an interactive display require connecting a computer?

No. Most modern interactive displays have a built-in Android system. This means they operate as standalone devices – you can browse the internet, open Office files, write on a virtual whiteboard, or play videos on them without connecting an external laptop. However, if a teacher prefers to work on their own computer, all it takes is connecting it to the display with a single cable.

Can you write on the display with a regular marker?

No, special styluses included in the set or simply... your own finger are used on the surface of the display! Touch technology precisely recognizes line thickness and erasing content with your palm.

How to mount the display in a classroom?

Displays can be hung directly on the wall using a bracket. An alternative is mobile wheeled stands, which allow for easy movement of the display between different classrooms (check our electric stand Avtek TS Electric Stand Light). Another solution is the wall-to-floor mounting system Avtek PylonLift enabling smooth, mechanical adjustment.

What if the school plans to purchase through co-financing / grants?

AV equipment purchased from government or EU programs must meet specific formal and technical requirements (e.g., appropriate warranty period, safety certificates, port specification). It is worth choosing suppliers who offer support in preparing tender specifications.

Invest in equipment that will serve for years

Choosing the right interactive display for a school is an investment for years that genuinely raises the quality of teaching and engages students. By choosing proven AV solution manufacturers, an institution gains not only solid equipment, but also full technical support, a warranty, and training for teaching staff.

In the retail and services sector, the fight for customer attention is fiercest. Static posters in shop windows rarely manage to break through the information noise. This is where professional digital signage displays come into play. Dynamic video spots, moving graphics, and smoothly changing restaurant menus (so-called digital menu boards) act like a magnet on the human eye. These systems allow for centralized content management – a retail chain can change prices, introduce an hourly promotion (e.g., Happy Hours), or adapt the offer to the current weather outside in a fraction of a second. This is a powerful marketing tool that really increases the average shopping cart value.

Flexibility tailored to your needs – from 43 to 98 inches

The greatest advantage of modern information display systems is their incredible scalability. Whether you need a discreet room booking screen or a giant advertising medium, the Avtek product range offers a wide spectrum of sizes (from 43" to 98"). Importantly, professional interactive displays differ significantly from regular home TVs in their design. They are built for continuous operation (in 16/7 or 24/7 modes), feature much higher brightness panels to prevent light reflections, and can operate in both landscape and portrait orientations, which opens up completely new possibilities for space arrangement.
