A Rear Window Digital Display is a digital display device installed within a vehicle's rear window area, falling under the category of flexible, vehicle-mounted LED display equipment. Utilizing a pixel matrix, it presents text, graphics, informational prompts, or dynamic visual content, thereby transforming the rear of the vehicle into a distinct and recognizable information display zone. Rear Window Digital Displays are commonly found in applications such as vehicle customization, mobile advertising, personalized vehicle styling, and promotional fleet displays. Typically featuring a black screen body, the design is optimized to meet the specific requirements of rear-window installation, balancing the constraints of the interior mounting position with the visual impact perceived from the vehicle's exterior. By transforming the rear window from a mere pane of glass into a digital content portal, this device serves as an ideal medium for conveying brand messaging, driving alerts, event-specific content, and personalized visual expressions.

1. Vehicle Window Dimensions and Fit

The C1-A screen measures 608mm x 169mm (x2 units), with an overall thickness kept to a slim 2mm, making it ideally suited for mounting within the rear window area. The 608mm length covers a wide visual display range, while the 169mm height ensures content clarity without occupying an excessive amount of rear window space. The black finish of the display unit blends seamlessly with the tint of automotive glass; consequently, the C1-A Rear Window Digital Display offers a more natural and integrated visual appearance once installed, making it compatible with the rear window layouts of a wide variety of vehicle models.

2. Bluetooth Connectivity and Control

The C1-A Rear Window Digital Display utilizes Bluetooth technology to connect with the Surplife App, facilitating convenient, short-range management of display content from inside the vehicle cabin. This Bluetooth-based connection method minimizes interference from external data cables, allowing users to edit text, graphics, and dynamic content directly via their mobile phones, while a wireless 24-key remote control enables quick and effortless switching between different displays. In a typical in-vehicle environment, the Bluetooth connection range is generally sufficient to meet operational requirements within the cockpit, thereby making the C1-A Rear Window Digital Display easier and more convenient to manage during daily use.

3. Dual-Screen Pixel Layout

This Rear Window Digital Display features a 36x12x2 pixel configuration, utilizing a dual-panel modular design that is ideal for displaying content across distinct zones. Each individual screen generates a crisp LED dot-matrix image; when combined, the two panels enable a richer and more versatile arrangement of information. The 36x12x2 pixel layout is well-suited for displaying short phrases, symbols, directional cues, and simple animations, meeting the legibility requirements for rear-window viewing distances while ensuring the content remains uncluttered.

4. Wide-Voltage Vehicle Input

This device supports a DC 12–24V input voltage range, making it compatible with the power supply environments found in a wide variety of vehicles—including standard passenger cars, commercial vehicles, and trucks. While 12V systems are commonly found in private automobiles and 24V systems in certain commercial vehicles, this broad voltage compatibility significantly enhances installation flexibility. Operating directly off the vehicle's power supply, the Rear Window Digital Display ensures stable brightness and consistent content presentation, effectively meeting the operational demands of mobile environments.

5. Dual-Language Support (Chinese & English)

The C1-A supports content display in both Chinese and English, catering to the diverse display requirements of vehicles across different regions. When editing content via the Surplife App, users can select Chinese, English, or a combination of both languages to suit their specific target audience. The included wireless 24-key remote control allows for the rapid switching of pre-set content. Furthermore, with packaging dimensions of 160mm x 155mm x 185mm, the product is designed for ease of storage, shipping, and retail store display management.

With dimensions of 608mm x 169mm x 2, the unit fits most rear window spaces; its black casing blends seamlessly with the glass background, making it ideal for daily commutes, weekend trips, and vehicle personalization.

2. Taxi Rear Windows

For taxis, the Rear Window Digital Display is perfect for displaying service notifications, availability status, route information, or brief advertisements. As the vehicle navigates city streets, the content on the rear window remains clearly visible to following vehicles and pedestrians. The Bluetooth-enabled app management system makes it easy for drivers to update content, while a 24-key wireless remote allows for quick switching between preset messages—catering perfectly to the dynamic display needs of mobile service vehicles.

3. Ride-Hailing Vehicle Rear Windows

Ride-hailing vehicles can utilize the Rear Window Digital Display to show ride status (e.g., "On a Trip"), vehicle identifiers, welcome messages, or promotional details. Support for both Chinese and English content meets the multilingual requirements of environments such as airports, hotels, and business districts. The dual-panel 36x12x2 pixel layout is optimized for displaying short phrases and symbols, ensuring content remains concise and legible, thereby helping the vehicle stand out more prominently during passenger pick-up and drop-off services.

For vehicles involved in corporate hospitality, trade shows, or event logistics, the information displayed on the rear window significantly improves vehicle identification efficiency. The DC 12–24V input is compatible with the power systems of various business vehicle models, while the Surplife app allows for pre-editing content, enabling rapid switching to suit the specific requirements of different assignments.

5. Exhibition Vehicle Rear Windows

Exhibition vehicles can leverage the Rear Window Digital Display to feature booth numbers, new product announcements, brand slogans, or directional signage for events. When the vehicle is parked outside an exhibition hall, at a park entrance, or within a temporary display zone, the rear window screen serves as a mobile visual focal point. The 608mm wide-screen format is ideal for conveying short messages effectively, and the black casing creates a sharp contrast against the vehicle window, thereby enhancing the overall visual impact of the on-site display.
