The future of public transportation is not only about eco-friendly vehicles — it’s also about how essential information reaches passengers. E-paper display technology is ushering in a new era in urban infrastructure by providing a fast, simple, and sustainable solution for passenger information. Discover how the technology works and what benefits it offers in our article!

The HC Linear SmartPage is an e-paper passenger information display — a low-power, real-time information device designed specifically for outdoor use.

The 13.3-inch electrophoretic (E-INK) displays feature a 1600×1200 pixel resolution, 16 levels of grayscale, and excellent readability even in daylight. At dusk, the built-in light sensor automatically activates the backlight, ensuring the content remains visible at all times. The displayed information stays stable without network power, making the display ideal for autonomous operation, including solar-powered setups.

The display is powered by a 20W solar panel mounted on a pole and a built-in 20Ah battery, which can be optionally expanded. Its energy consumption is minimal, allowing it to operate for up to two weeks without charging, resulting in significant savings in operation and maintenance. This ensures that information is reliably available, regardless of weather conditions or network power supply.

Our displays are compatible with the GTFS-RT standard, enabling real-time display of schedules, delays, early arrivals, and traffic information. The built-in LTE modem, along with optional WiFi, LoRaWAN, and Ethernet interfaces, allow for remote content updates and system monitoring. Accessibility features include physical buttons and 433.92 MHz remote control operation. Additionally, the integrated TTS (text-to-speech) function supports multiple languages and adjustable volume.

Our proprietary, online cloud-based management system, SmartPage, allows content editing anytime, anywhere—requiring only a web browser with internet access, delivered as a SaaS service. The system supports not only the display of transportation information but also the dynamic publishing of announcements, news, local information, and events. Creating online surveys is also simple. Updates are applied instantly, with the option to schedule content in advance. Transparency and ease of use were primary design goals for the system.

Powder-coated steel housing (available in RAL color options), 4 mm thick IK09-rated anti-glare tempered glass, and IP65 protection ensure the durability of the display. It operates reliably in temperatures ranging from -15 °C to +65 °C — whether installed on a platform, bus stop, or information hub. This device is not just hardware, but a reliable, long-lasting element of the digital infrastructure for the cities of the future.

HC Linear’s SmartPage displays, built on e-paper technology, offer a solution that addresses sustainability, economic, and IT challenges simultaneously. By replacing paper-based schedules and notices, maintenance costs are reduced—there’s no need for printing, swapping, or on-site updates anymore. This saves significant resources and fuel while avoiding unnecessary CO² emissions. For passengers, one of the biggest benefits is that information is always accessible, real-time, accurate, and easy to read.

At HC Linear, we develop electronic systems, from research to manufacturing to integration. The reliability of our products depends not only on design but also on precise, high-quality execution. Our technicians play a key role in this process, contributing beyond just repairing units that fail to test.

If you’re curious about what a technician’s workday looks like at HC Linear, the technologies we use, and what you can expect as a professional on our team, read on.

At our research and development center in Pécs, we operate advanced SMT (surface-mount) and THT (through-hole) production lines, along with a dedicated assembly area. These in-house capabilities allow us to respond quickly and flexibly to the needs of our development team—whether it’s prototype manufacturing or small series production. With a broad product range, our technicians are involved in a wide variety of tasks.

As a member of our team, you’ll be involved in various manufacturing and inspection processes throughout your day. The production of our LED displays is a great example of this. Watch our short video to see how it works:

Our technicians perform a wide range of tasks — from preparing components and materials to configuring the conveyor system and carrying out inspections, they oversee and execute the entire production process. At times, they may also be diagnosing a product that has returned for repair.

Of course, we don’t expect you to have experience in every area from day one. Our goal is to involve you in tasks that best match your skills and interests, while also allowing you to explore new technologies and workflows. Our experienced colleagues are happy to support your onboarding — whether it’s learning to operate machinery or getting familiar with software tools. You can always ask questions — we work as a team and never leave anyone on their own.

The workday is made easier by a single-shift schedule, fresh coffee, fruit, and a positive atmosphere. Collaboration is very important to us: regular team-building activities and company events strengthen our sense of community.

If you’re passionate about electronics, enjoy working with precision, and want to be part of a supportive, growth-driven community, this is the place for you. Check out our current job openings and join us!

Innovation shapes the future, particularly in healthcare, where cutting-edge technology can improve diagnostics and streamline patient care. Guided by this belief, we proudly contributed to the Borsóház-Pécs Foundation’s efforts to acquire the R-Gait robotic gait trainer, a state-of-the-art rehabilitation device.

Borsóház-Pécs is dedicated to helping children with neuromotor and musculoskeletal challenges regain their mobility. Their expert therapists work tirelessly to restore lost or weakened motor functions, and cutting-edge technology plays a crucial role in making rehabilitation more effective. By integrating state-of-the-art solutions like the R-Gait system, they provide young patients with better opportunities for recovery and improved quality of life.

Thanks to the collaboration of local organizations and supporters, the R-Gait robotic gait trainer is now available in Pécs, marking a significant milestone in rehabilitation care. This innovative device assists patients in relearning natural walking patterns by providing controlled weight support and pelvic stabilization. Equipped with sensors and haptic feedback, it enhances therapy by offering real-time adjustments to optimize movement.

We are proud to have contributed to the total cost of bringing Hungary’s first R-Gait system to Pécs.

At HC Linear, we see innovation as more than just technological progress—it’s about driving meaningful change. Supporting initiatives like this reinforces our commitment to advancements that make a meaningful difference in people’s lives. The work of Borsóház-Pécs is a powerful example of how innovation can transform rehabilitation and open new possibilities for those in need.
