• Color accuracy and gamut

  Micro LED displays produce multiple colors very well. First, the displays have a high color contrast ratio. This means they can render very bright colors and very dark colors. Secondly, they offer a wide color gamut. This allows micro LED displays to produce more shades and colors. The wide color gamut and high color contrast ratio make the displays produce accurate and vibrant colors.

• Flexible and scalable

  The micro LED technology is very flexible. It can be adapted to different types of display surfaces. This includes small curved screens, large video walls, and even wearable devices. Micro LED technology is also scalable. This means it can be used to manufacture displays of various sizes. These sizes can range from small smart watch screens to very large stadium displays.

• Longevity and durability

  Micro LED displays are very durable. They can last for many years without showing signs of burn-in or image retention. This is a common problem in OLED displays. It occurs when the screen retains a faint shadow of a previous image. The durability of micro LED displays makes them ideal for long-term use.

How to choose Micro LED

When purchasing a Micro LED display, several factors must be considered to ensure the display meets the intended application requirements. Here are some key factors to consider:

• Brightness and Resolution

  Micro LED displays are known for their high brightness levels. However, it is important to consider the specific application environment. For instance, if the display will be used in a dim or dark room, a display with lower brightness levels may be sufficient. On the other hand, if it is to be used in a well-lit environment, a display with higher brightness levels should be considered.

  In addition to brightness, LED resolution should also be considered. Ideally, the number of pixels in an image determines its sharpness. Therefore, when the number of pixels is increased, a sharper image is produced. When purchasing an LED display, choose one with a higher pixel density to ensure better picture quality.

• Size and Form Factor

  Micro LED displays can be tiled together to form a display of any size and shape. Therefore, when considering the size of the display, consider the space available for the screen. More importantly, consider the distance between the viewers and the screen. If the distance is long, consider purchasing a larger Micro LED screen. The displays are also available in different aspect ratios. Choose an aspect ratio that will fit the intended space or area where it will be placed.

• Color Performance

  When it comes to color performance, look for displays with a wide color gamut. Such displays are capable of producing vivid and dynamic colors. More importantly, look for displays with good color uniformity. This is because any application that requires high-quality images or videos will be negatively affected by color variation across the screen.

• Viewing Angle

  Viewing angle is the maximum angle from the screen at which the picture is still clearly visible. A wide viewing angle allows multiple viewers to see the content clearly from different angles. This feature is important for displays that will be used in areas with a large number of viewers.

• Durability and Lifespan

  Micro LED displays are known for their durability and longevity. This is because they are made with highly durable materials. When purchasing, consider the display's durability and expected lifespan.

• Compatibility and Integration

  The Micro LED display should be compatible with the existing hardware and software systems. More importantly, it should be easy to integrate. Consider the connectivity options available for the display. These include HDMI, DisplayPort and DVI. Also, consider the content management system for easy control and operation.
