How to Choose Transparency for Outdoor Transparent Screens: The Trade-off Between Transparency and Display Clarity

In principle, the transparent screen uses a hollow light-bar architecture: for the same area, to get higher clarity you must arrange more LEDs and reduce the pixel pitch; as the proportion of LEDs and PCB light bars rises, the hollow gaps decrease and transparency falls. Conversely, to pursue higher transparency, the pixel gaps must be enlarged and the pitch widened, reducing the number of pixels per area, so close viewing easily shows graininess and weaker image detail. Viewing distance is the core yardstick for selection; you cannot blindly pursue higher transparency or a smaller pixel pitch alone.

Our TM1000 series outdoor transparent LED screen has a standard pixel pitch of 15.625mm vertical and 31.25mm horizontal, corresponding to a transparency range of 35%-70%, fitting the vast majority of building facade and glass curtain wall long-distance advertising projects. For different overseas projects, custom pixel pitches are supported to balance clarity and transparency.

If the project prioritizes building transparency and daylighting—for example, a landmark glass curtain wall with a main viewing distance above 15 meters—a high-transparency configuration can be chosen, widening pixel gaps and prioritizing building appearance and daylighting; at long distance the human eye cannot make out grain, and text and video ads still play normally. For a street-facing mall curtain wall with close-viewing scenarios and high requirements for text and detail images, a denser custom pixel pitch is chosen, sacrificing some transparency in exchange for higher pixel density to ensure close images are clean and clear.

When giving selection advice to overseas clients, you cannot look only at the numbers on the spec sheet; you must comprehensively assess the project's actual viewing distance, curtain wall daylighting needs, and content type. Playing simple slogans and dynamic graphics can use a higher-transparency solution; playing portraits and fine images requires moderately lowering transparency and increasing pixel density. Through flexible pixel-pitch customization, the TM1000 helps clients find the project's optimal balance, avoiding the undesirable results of "transparent but blurry, or clear but fully blocking the glass curtain wall."
