Jingda Display's Stretched Bar Screen Is Applied To Buses

With the rapid advancement of smart urban transit construction worldwide, traditional public transport information delivery methods, including static paper posters and single-function indicator lights, can no longer meet the diversified, real-time and intelligent operation needs of modern urban bus systems. As a specialized ultra-wide display device, the stretched bar display has gradually become the core display hardware for bus intelligent renovation by virtue of its unique ultra-long and narrow aspect ratio, space-saving structure and high environmental adaptability. Matched with professional industrial-grade LCD monitor control systems and display technologies, stretched bar displays have achieved in-depth penetration in multiple bus application scenarios, covering passenger information guidance, commercial advertising operation, vehicle safety prompts, intelligent scheduling feedback and other key fields.

What is stretched bar display?

A stretched bar display—often referred to in the industry as a bar-type LCD monitor—is engineered with native ultra-wide aspect ratios typically reaching 32:3, 16:4.5, or fully custom resolutions such as 3840x720 or 1920×720. Unlike cropped standard panels that waste 60 to 80 percent of backlight power on masked areas, native stretch bar panels utilize the entire LCD cell, delivering superior thermal performance, lower power consumption, and chassis depths as slim as 25 to 35 millimeters.

Jingda Display assisted one of our Korean clients in successfully developing a 43 inch LCD monitor, which is mainly used for real-time bus route announcements. After repeated validation from samples to small batches, the project has been successfully mass-produced and applied on buses. The following image is the physical picture and application scenario of JDA's stretched bar display.

JDA support customize 36 inch, 37.6 inch stretched bar screen digital signage LCD display monitors according to clients’ requirements, like dimension, thickness, interface, IC, power cable and so on. The 43 inch monitor, with its advantages such as high resolution, flexibility, and energy efficiency, to meet diverse display needs.

The advantage of stretched bar display

The large-scale popularization of stretched bar displays in bus systems is not accidental, but based on the perfect matching between its technical characteristics and the special operating conditions of buses. Industrial-grade LCD monitor technology provides stable hardware and software support for the long-term operation of stretched bar displays on vehicles, solving many pain points of traditional display equipment in public transit scenarios.

Space Adaptability and Structural Optimization

The internal and external installation spaces of buses are extremely limited. The top of bus carriages, the upper part of carriage doors, the tail of vehicles and the side body reserved for display equipment are all narrow strip areas. Traditional square or rectangular LCD monitors cannot be embedded and installed perfectly, and exposed installation will occupy passenger space, affect vehicle aesthetics, and even bring potential safety hazards. The customized strip structure of the stretched bar display is completely tailored to the spatial characteristics of buses. It can be seamlessly embedded in various narrow installation positions without modifying the original vehicle structure, realizing zero-space occupation and integrated installation.

Industrial-Grade Environmental Adaptability

Bus display equipment needs to operate stably for a long time in complex and variable environments, including high-temperature exposure in summer, low-temperature frost in winter, vehicle jitter during driving, and strong light interference from outdoor sunlight. Professional bus-mounted stretched bar LCD monitors adopt industrial-grade LCD panels and full-sealed waterproof and dustproof design, with a working temperature range of -20℃ to 70℃, which can adapt to extreme weather changes in different regions of the world.

Intelligent and Expandable System Performance

Modern bus-mounted stretched bar displays are equipped with intelligent LCD monitor control systems, supporting multiple network connection methods such as 4G, 5G and WiFi, realizing remote real-time data update and content management. Operators can uniformly update bus route information, announcement content and advertising materials through the background management system without on-site manual replacement, which greatly improves operation efficiency
