The transparent LED display from visslighting is very popular in our country. The uppermost 75% transparency rate makes the background clearly visible when the screen is off and presents a special visual effect when the screen is on.
How to solve the inconsistency LED performance parameters, there are two main technologies industry ways: First, by further subdivision of LED specifications to improve the consistency of the performance of LED; the second is through a subsequent correction of ways to improve the display uniformity. Follow-up correction from earlier modules, the module calibration, development of today's by point correction. Correction from simple light intensity correction, color coordinate the development of light intensity correction.

The technology development of indoor LED display is very quick these years. The electrical parameters are not enough consistency to other electronic components. Therefore, we conclude that the practice: Subsequent correction is only symptomatic, and LED segments are the fundamental parameters, transparent indoor LED display is the future mainstream industry.

In terms of the relationship between uniformity and clarity of the display, the industry there is often erroneous understanding. Simply reduce physical pixel pitch increased resolution while ignoring uniformity, to improve the clarity is no doubt. Imagine a grave there, "dust effect" and "mosaic" of the indoor transparent LED display, even though its physical pixel pitch and then a small, high-resolution and then, it is impossible to get a good image clarity.
