How to Spot Quality in LED Displays

The rapid development of the LED display industry has made LED displays more and more popular among the public. For those who are new to this field, how to judge the quality of LED displays is an important issue.

Brightness:

Luminance is a key performance metric for LED display panels, pivotal in assuring that visuals are rendered in crisp detail. A greater level of luminance correlates directly with enhanced clarity of the image on the display. Conversely, at an equivalent screen resolution, diminished brightness results in a less distinct image presentation.

Colour:

The visual attributes of LED screens are delineated by factors like the total number of colors, levels of grayscale, and the breadth of the color spectrum. Because each color comes with a distinct level of purity, they have individual counts and grayscale intensities. Depending on the application, different colors can be chosen. The level of grayscale is a pivotal quality metric for LED displays, indicating the spectrum of brightness to darkness a color can have. The finer the shades of color, the higher the grayscale level, enhancing clarity for the viewer. A common standard for high-quality LED screens is a display of a 16-level grayscale.

Luminance uniformity:

LED screen brightness uniformity is all about ensuring that the light output is consistent across adjacent modules during color-rich displays.

For quality control, this characteristic of LED screens is typically gauged through a visual comparison. This process involves checking the light intensity at individual points within a module while it displays various colors, and then comparing these values to those of other modules. Inconsistencies in brightness can result in what are known as “dark spots.” To measure brightness levels more precisely, there is software designed to analyze and compare light intensity between modules. A discrepancy in brightness of 10% or more is usually the threshold for identifying a dark spot.

As LED screens consist of many smaller modules, the overall appearance of uniform brightness can be affected by how uniformly these modules shine. Paying attention to brightness uniformity is important when choosing an LED screen.

Color reproduction:

Color fidelity in LED display screens refers to how accurately these screens can maintain the consistency of colors at varying levels of brightness. Typically, LED screens are designed to adapt their brightness based on the ambient light — appearing brighter in dim settings and dimmer in well-lit settings. To achieve a true-to-life color representation, it’s crucial to implement color reproduction technology. This ensures that the colors on the screen match those in the actual environment, providing a realistic visual experience.
