Bar-Type LCD Screens: Applications and Selection Guide

News 2026-03-13

Bar-type LCD displays (also known as stretch LCD displays) are finding increasingly widespread application in both commercial and industrial sectors. Unlike traditional screens with 16:9 or 4:3 aspect ratios, these bar-type displays feature an ultra-wide, elongated aspect ratio, enabling them to better accommodate specialized spatial constraints and information display requirements.

What is a Bar-Type LCD Screen?

A bar-type LCD screen is a specialized LCD display characterized by an aspect ratio that is significantly wider than that of standard displays. These screens are typically produced either by cutting down standard LCD panels or through specialized design and manufacturing processes. Common aspect ratios include 16:3, 21:9, 24:5, and 32:9, with options available for even longer, custom-tailored ratios.

Bar-type screens typically utilize TFT LCD technology and are equipped with LED backlighting systems, enabling them to deliver stable display performance and a long operational lifespan.

Key Application Scenarios for Bar-Type LCD Screens

Smart Retail and Digital Signage

In the retail sector, bar-type displays are frequently utilized for shelf-edge advertising, product price tags, in-store information screens, and mall navigation displays. These elongated screens can be mounted along shelf edges or within narrow spaces, effectively utilizing available room to showcase promotional information.

Transportation and Public Information Systems

Bar-type LCD screens are widely utilized in the transportation sector—for instance, in subway train information displays, electronic bus stop signage, airport flight information screens, and highway information dissemination systems. These screens are ideally suited for the scrolling display of text-based information and real-time data.

Industrial Equipment and Control Systems

In industrial equipment, bar-type LCD screens can be utilized for: production line status displays, instrumentation and monitoring interfaces, and control terminals for automated machinery.
These bar-type screens can be installed within narrow panel areas on equipment, thereby conserving space and enhancing the efficiency of information display.

Intelligent Transportation and In-Vehicle Displays

In intelligent transportation systems, bar-type LCD screens can be utilized for a variety of applications, including in-vehicle information displays, subway car advertising screens, travel information panels, and intelligent bus systems. These screens typically require high brightness and a wide operating temperature range.

Key Features of Bar-Type LCD Screens

High Space Utilization

Bar-type screens can be installed in narrow or elongated spaces, such as on shelves, above doorways, or on equipment panels.

High Information Display Efficiency

    Ideal for displaying scrolling text, information lists, or advertisements.

    Supports Custom Sizes

    Many bar-type displays support customization—such as 8.8-inch, 19-inch, 28-inch, 37-inch, and 48-inch models—and can even be designed in special dimensions to meet specific device requirements.

    High-Brightness Design

    Many bar-type displays support brightness levels of 700 nits, 1000 nits, and 2000 nits, making them suitable for outdoor or high-ambient-light environments.

    Key Selection Parameters for Bar-Type LCD Screens

    When selecting a bar-type LCD screen, it is essential to focus on the following technical parameters.

    Screen Size and Aspect Ratio

    Common bar-type screen sizes include: 8.8-inch, 19-inch, 28-inch, 37-inch (stretched), and 48-inch displays. When making a selection, the appropriate size should be determined based on the available installation space within the device.

    Resolution

    Bar-type displays typically utilize specialized resolutions—such as 1920 × 360, 1920 × 540, 3840 × 720, and 1280 × 480—where high resolution enhances the clarity of text and images.

    Screen Brightness

    Select brightness based on the usage environment:
    Indoor: 300–500 nits
    Commercial Display: 500–700 nits
    Semi-outdoor: 700–1000 nits
    Outdoor: Above 1000 nits

    Viewing Angle

    We recommend selecting a bar-type screen with an IPS panel; the typical viewing angle is 178°/178°, making it ideal for display in public environments.

    Interface Types

    Common interfaces include LVDS, HDMI, MIPI, and eDP; among these, the LVDS interface is the most prevalent in industrial equipment.

    Operating Temperature

    Industrial or outdoor environments typically require a wide-temperature design: Operating Temperature: -20°C to 70°C; Storage Temperature: -30°C to 80°C.

    Backlight Lifespan

    The typical requirement for LED backlight lifespan is ≥ 50,000 hours; a long lifespan helps reduce maintenance costs.

    Summary

    Thanks to their unique elongated aspect ratios, flexible installation options, and efficient information display capabilities, bar-type LCD screens have been widely adopted across various sectors, including retail, transportation, industrial control, and public information systems.

    When selecting a model, it is recommended to prioritize the following factors:

    Screen Size and Aspect Ratio

    Resolution

    Brightness

    Panel Type

    Interface Type

    Operating Temperature

    Backlight Lifespan

    Choosing the appropriate bar-type LCD screen not only enhances the display performance of the device but also improves the overall system stability and user experience.
