DOOH is an abbreviation for Digital Out-of-Home. It refers to a multimedia marketing and advertising approach that uses digital displays in public spaces to deliver dynamic or static content. Common application locations include metro stations, airports, department stores, shopping malls, parks, and train stations. In general, any digital display installed in a public area with pedestrian traffic falls within the scope of DOOH.
What Are the Advantages of DOOH?
Compared with traditional printed media or static advertising billboards, DOOH offers outstanding advantages in digitalization and real-time capability.
Why is digitalization an advantage? In recent years, growing environmental awareness has encouraged the reduction of paper usage, which helps lower deforestation and supports global sustainability efforts. As a result, digitalization has long been a well-established practice in DOOH implementations.
As for real-time capability, DOOH allows content to be updated easily through computers or internet connections. This eliminates the need for physical replacement or construction work, significantly reducing operational inconvenience when compared to traditional billboards.
What Types of Digital Screens Are Used in DOOH?
From the early days of the digital era until now, LCD displays have been the dominant devices used in DOOH applications. However, as of 2026, DOOH is no longer limited to LCD screens alone.
With reducing carbon footprints and achieving ESG (Environmental, Social, and Governance) goals becoming key priorities in modern corporate governance, alternative solutions to LCD displays have emerged. One such solution is ePaper.
ePaper is a type of digital display that simulates the appearance of traditional paper. It typically consumes significantly less power than conventional LCD displays while still delivering effective digital media messaging. For a detailed explanation of how ePaper works, please refer to the technical overview provided by ADS.
The Future of DOOH and ePaper Displays
High foot traffic translates directly into commercial value. DOOH provides brands with high visibility and centralized digital content management, creating greater overall value.
Traditionally, most DOOH applications have relied on LCD displays. However, LCD technology comes with inherent drawbacks such as high brightness glare, high power consumption, and complex cabling requirements. In response to the growing focus on sustainable operations, ADS has dedicated itself in recent years to the development of ePaper display signage.
By adopting ePaper panels developed by E Ink and further integrating circuit systems and software platforms, ADS has successfully launched products such as the Solis 32 EPD.
Furthermore, as DOOH continues to be a long-term and effective solution for brand exposure, and since outdoor digital signage typically requires large format displays. ADS is actively collaborating with E Ink on the development of Large ePaper Displays.
As part of this development, ADS is advancing the design and integration of 75″ ePaper Display signage, leveraging large-format color ePaper technology to deliver low-power, sustainable, and high-visibility solutions for outdoor DOOH applications.
We believe that in the near future, our 75-inch color ePaper display signage will further transform the DOOH ecosystem.
Who can provide sustainable DOOH screens?
Agile Display Solutions (ADS) is your trusted partner for sustainable DOOH solutions.
With over a decade of experience in digital display technologies, ADS has recently focused on developing environmentally friendly ePaper-based digital signage solutions that address the growing demand for sustainable outdoor advertising.
Our color ePaper digital signage solves many of the challenges associated with traditional static posters and conventional LCD displays:
1.Static posters require significant manual labor for installation, and every content update demands another round of physical replacement.
2.During digital transformation, DOOH deployments are often constrained by power supply, connectivity, and infrastructure costs.
3.Conventional LCD and LED screens frequently face light pollution concerns and local regulatory restrictions.
By replacing traditional posters and LCD/LED screens with ePaper digital displays, labor requirements are limited primarily to the initial installation.
Subsequent content updates can be completed remotely through a CMS backend system via wireless connectivity—eliminating the need for on-site intervention.
In addition, ADS ePaper solutions:
- Do not generate light pollution, making them suitable for regulated outdoor environments.
- Feature a low-power frontlight design optimized for sunlight readability, ensuring clear visibility at any time of day.
ADS delivers a sustainable, low-energy, regulation-friendly DOOH solution designed for the future of digital outdoor advertising.
