We suggest taking a closer look at this topic and determining which tasks are best suited for consumer TVs and which for professional displays. Which solutions are better equipped to ensure visibility and attract customers, even on a sunny day?

 

 

How to attract the attention of passersby

 

Store owners are always looking to capture the attention of people walking by their shops, using various marketing, psychological, and visual techniques. The storefront is the “face” of the business—it’s what determines whether a potential customer will be curious enough to come in or simply pass by. One of the most effective ways to attract attention today is by using bright, dynamic video content displayed on a screen in the shop’s front window.

 

Usually, store owners believe it’s enough to install a regular TV like the one they use at home. But in reality, a television bought from a home electronics store is not suitable for such operating conditions.

 

 

The importance of screen brightness

 

Display brightness is measured in nits – a unit of luminance also known as a candela per square meter (cd/m²). It indicates how much light a screen emits when showing a completely white image. The higher the number of nits, the brighter the screen.

 

– A nit, or candela per square meter (cd/m²), is a unit for measuring brightness.

 

– One nit equals the brightness of a surface that lights up evenly across 1 square meter in a perpendicular direction with a luminous intensity of 1 candela.

 

 

Why is almost nothing visible on a TV in a shop window during the day?

 

The main reason is the impact of external lighting. On a bright sunny day, outdoor light levels can exceed 100,000 nits, whereas inside a store they typically don’t go beyond 700 nits, and in a home setting – no more than 300 nits. Consumer TVs offer a brightness of around 300–500 nits. To keep an image clear and visible, screen brightness must be significantly higher than ambient light levels. That’s why a TV works fine inside a house or a dim store, but fails in bright daylight.

 

– Normal indoor lighting (~100–300 nits) — the TV image is clearly visible.

 

– Outdoors in shade or overcast weather (~1,000–5,000 nits) — the image is still readable but loses contrast.

 

– In bright daylight without direct sun (~10,000–25,000 nits) — the image becomes hard to see.

 

– In direct sunlight (~50,000–100,000 nits) — the TV screen is nearly invisible.

 

 

Digital signage as a solution for storefronts

 

To effectively display content in store windows and attract passersby’s attention, digital signage technologies are being used more and more. This refers to specialized software for digital signage systems that enables bright, high-contrast, dynamic content that adapts to varying outdoor light conditions.

 

Using digital signage players along with digital signage software makes it possible not only to manage content remotely, but also to ensure its optimal quality and brightness. These solutions support digital menus, especially useful for restaurants and cafés where screens show colorful images of dishes and promotions.

 

LED screen software provides high brightness and contrast, making content readable even in strong lighting conditions. LED screens offer much higher brightness levels than consumer TVs, making them the perfect choice for outdoor use.

 

 

How to attract the attention of passersby using digital signage?

 

– Use bright, dynamic video content that changes and grabs attention.

 

– Implement a digital menu with high-quality images and information about promotions.

 

– Manage content remotely using digital signage software that allows for quick updates.

 

– Use digital signage players that ensure stable and high-quality broadcasting.

 

– Install LED screens with high brightness to ensure visibility even in sunny weather.

 

Using digital signage in storefronts is not just about showing ads — it is part of a comprehensive marketing strategy that increases brand awareness, attracts more customers, and boosts sales.

 

 

When it’s hot: challenges for digital advertising in storefronts

 

Sunlight not only provides illumination but also generates significant heat, which affects all objects exposed to the open air. A regular TV indoors, at temperatures of 22–25°C, heats up to 40°C, but in a shop window, additional heat from the sun can raise the screen temperature to 60–80°C. This creates serious risks for the stable functioning of the device, especially if it is used to display important advertising content throughout the day. In such conditions, even the highest-quality consumer electronics may quickly fail, leading to additional expenses for repairs or equipment replacement.

 

Most consumer TVs are designed to operate in temperatures from 0 to 40°C, which is suitable for home use. However, in a storefront window, when the temperature exceeds 50–60°C, the plastic casing begins to deform, and at 80–90°C, the electronics may overheat. When LCD panels are exposed to intense heat, colors may shift, and spots and artifacts may appear on the screen surface — issues that are not covered under warranty. Such damage not only worsens the appearance of the device but may also render it unusable, reducing the effectiveness of digital advertising during peak hours.

 

 

How to reduce screen heating?

 

There are various methods for lowering device temperature in a storefront window:

 

– Moving the screen deeper into the store to shield it from direct sunlight.

 

– Using canopies or special sun-protection films.

 

– Organizing proper ventilation and air conditioning in the installation area.

 

However, even with these measures, it is not always possible to achieve the desired result, especially during hot summer days. In addition, such methods may require extra financial investment and may not always ensure long-term device operation. For modern digital advertising, it is important that the system functions consistently and continuously, regardless of weather conditions.

Professional solutions for digital signage

 

For outdoor advertising, it is advisable to use specialized advertising screens that are designed to operate in challenging conditions. Such displays feature:

 

– An active cooling system and efficient heat dissipation.

 

– A protective screen coating that prevents the LCD panel from overheating.

 

– A steel casing that withstands high temperatures.

 

Professional screens for digital signage systems are designed for prolonged 24/7 operation, which is especially important for shops, cafés, and other venues with high visitor traffic. Thanks to high brightness and contrast, such screens remain clearly visible even in direct sunlight, ensuring the effective performance of digital advertising at any time of day.

 

 

Advantages of CMS and Android players in digital signage systems

 

A modern digital signage system is based on the use of a CMS (Content Management System), which enables centralized control of content across various advertising screens. The Android set-top box is used as a convenient player for displaying digital ads.

 

– The CMS makes it possible to quickly update advertising materials on all devices, which is especially relevant for retail and restaurant chains.

 

– Android set-top boxes provide stable playback of videos and images, and support a wide range of media file formats.

 

– Advertising screens with high brightness and heat resistance guarantee visibility even on the hottest days.

 

Thanks to this integration, digital advertising becomes as effective as possible, and content management — simple and convenient. The digital signage system allows automation of the content update process, quick response to changes, and maintaining the relevance of promotional messages in real time. This opens up new opportunities for attracting customers and strengthening brand recognition, even in difficult weather conditions.

 

 

Glare: challenges for high-quality digital advertising in cafés and shops

 

Bright reflections from surrounding objects on the glossy screen surface are one of the main obstacles to clear visibility of information on digital menu boards in cafés. Glare can completely obscure important details, such as the size of a discount or a promotional offer, reducing the effectiveness of advertising. This is especially noticeable on sunny days when patches of light on the screen make the image unreadable for potential customers passing by.

 

That is why modern professional displays for digital signage solutions are equipped with a special polarizing coating. This coating minimizes glare and allows the content to remain clearly visible even when viewed through sunglasses. For cafés, where it’s important that digital menu boards are always readable, this technology becomes a key advantage.

Why a consumer TV is not the solution

 

Using a regular television in a shop or café window is a decision that almost always leads to disappointment. The main problems with this approach are:

 

– Insufficient brightness: Consumer TVs have a brightness of only 300–500 nits, so the image is practically invisible during the day. Your content gets lost in sunlight, and even a centralized video management system won’t help if the screen itself cannot properly display the information.

 

– Glare and mirror effect: Storefront glass together with the glossy TV surface creates a mirror effect, which makes even the brightest promotional materials appear unclear.

 

– Overheating and malfunction: In direct sunlight, the TV casing can reach temperatures of 70–90°C. This leads to panel burnout, processor failure, and a significant reduction in the device’s lifespan.

 

– No warranty for commercial use: Consumer TVs are not designed for intensive use in harsh conditions, and their warranty does not cover commercial application.

 

 

Advantages of professional digital signage solutions for cafés

 

A professional storefront display is the optimal choice for businesses wanting to get the maximum return from digital advertising. These screens offer several advantages:

 

– High brightness (1000–4000 nits): Thanks to powerful backlighting, information on digital menu boards remains visible even on the brightest days.

 

– Anti-glare coating: A polarizing layer minimizes reflections, ensuring image clarity from any viewing angle.

 

– Resistance to overheating: Professional displays are designed to operate at high temperatures and are equipped with efficient cooling systems.

 

– 24/7 operation: These digital signage solutions are ideal for cafés, restaurants, shops, and other venues where continuous information display is essential.

 

 

Centralized video management system and Android media players

 

Another benefit of modern digital signage systems is their use of centralized video management systems (CMS) in combination with Android media players. This approach makes it possible to:

 

– Quickly update content on digital menu boards in response to changes in promotions, menus, or schedules.

 

– Manage large numbers of screens at once — ideal for chain cafés and restaurants.

 

– Ensure stable playback of videos and images regardless of external conditions or time of day.

 

– Scale the system smoothly as the business grows, adding new screens and locations without complex setup.

 

 

Investing in professional digital advertising

 

In conclusion, using professional displays, integrating digital signage solutions, and applying centralized video management systems together with Android media players is a comprehensive approach that enables cafés and shops to attract customers effectively, enhance brand awareness, and get the most out of digital advertising.
