The LED dance floor comprises a series of interlocking LED tiles containing multiple light-emitting diodes (LEDs). The panels are usually made of durable tempered glass that can withstand dancers’ weight.
Understanding Pixel Pitch and Resolution
A gap between near pixels on a LED display is known as a pixel pitch, while a pixel’s total number on display is a resolution. These concepts work hand in hand to determine the quality of the visual output from your LED display.
The measurement of a pixel pitch is done in millimeters; the smaller the pixel pitch, the higher the resolution and the sharper the image display. Consequently, a smaller pixel pitch will be more costly than an LED with a larger one. With the right pixel pitch, you can balance cost and image quality.
The resolution, however, depends on the pixels on display at once. The image will be clearer and more detailed if the resolution is higher. As the resolution increases, so does the cost of the display.
Overall, what you intend to use the display for will determine the efficient resolution and pixel pitch that you will select. Outdoor promotion will require you to opt for a smaller pixel pitch and a high-resolution display. This way, you will get sharp visuals even from a distance.
You can select a screen with a lower resolution and a larger pixel pitch and still receive high-quality images if you need the LED display for indoor use. To create a design for an LED display of high quality, you must first comprehend how the pixel pitch and resolution function.
Choosing the Right LED Technology
If you find it hard to get used to LED display designs, you might not pick the right one. Understanding the various LED technologies and how they can benefit you is essential.
Consider the following when choosing the appropriate LED technology:
