What is the Difference in Pixel Pitch of LED Screens?

LED screens have become an advanced and popular media technology. Compared with display solutions such as LCD video walls or projectors, LED screens stand out thanks to their vivid colors, high stability, long life and wide viewing angle. These features make LED screens widely used in areas such as commercial advertising, smart surveillance, high-end conferences and command centers. For users, the viewing distance (also known as vision) of LED screens is an important factor, affecting the ability to spread advertising messages as well as the audience's viewing angle. So how to determine the optimal and maximum viewing distance of LED screens?

Calculate the viewing distance of the LED screen

What is pixel pitch?

Pixel pitch is the distance between two adjacent pixels and is usually measured in millimeters. With LED displays , a small pixel pitch means the pixels are closer together, which improves resolution and results in a clearer image. Conversely, a large pixel pitch is suitable for long-distance viewing situations where it is difficult for viewers to discern individual pixels. This can help reduce costs and extend the effective viewing range.

Important Factors When Choosing Pixel Pitch

Viewing Distance : Viewing distance is an important factor in determining the type of LED display you should choose. For indoor applications where viewers stand close to the screen, small pixel pitches (such as P1.2 or P1.5) are ideal. Conversely, for outdoor applications such as billboards or stage backdrops, large pixel pitches (P5, P8, P10) are more suitable to save costs and optimize long-distance visibility.
Need for Indoor or Outdoor Use : With indoor LED screens , small pixel pitch helps viewers see details clearly without glare. However, with outdoor screens, the high brightness of LED bulbs can cause glare when viewers stand too close, so it is necessary to adjust the pixel pitch appropriately to achieve the best effect.
Investment and Maintenance Costs : The smaller the pixel pitch, the higher the resolution and the higher the production and maintenance costs. Therefore, businesses need to consider to ensure the choice meets both display needs and optimizes costs.

To calculate the viewing distance of an LED display , it is necessary to first understand the pixel pitch on the display. The pixel pitch on an LED display is the distance from the center of one pixel to the center of the adjacent pixel, usually denoted by P and measured in mm. For example, P10 indicates an LED display with a pixel pitch of 10 mm. In the industry, the formula for calculating the optimal viewing distance and maximum viewing distance of an LED display is usually as follows:

RGB color mixing distance (distance for three RGB colors to form a single color): viewing distance of full-color LED display = pixel pitch (mm) × 500 to pixel pitch (mm) × 1000.
Minimum viewing distance (for the LED screen to display images smoothly): minimum distance = pixel pitch (mm) × 1000.
Optimal viewing distance (for the viewer to see the clearest image): ideal viewing distance = pixel pitch (mm) × 1000 to pixel pitch (mm) × 3000.
Maximum viewing distance : maximum distance = screen height (m) × 30.

These formulas help determine the most suitable viewing range for LED displays, thereby optimizing user experience and improving message delivery efficiency.

When choosing an LED display, pixel pitch is an important factor.

To choose the right pixel pitch for your LED display , you need to clearly define your needs and usage scenarios. For close-up viewing applications, such as conference rooms, shopping malls, or museum signage, small pixel pitch LED displays (such as P1.2 or P1.5) will provide high resolution, allowing for clear and detailed images. These displays not only reproduce exquisite images, but also display precise text and information, making them ideal for close-up viewing.

On the contrary, for applications that require long-distance viewing, such as stage backdrops or outdoor billboards, large pixel pitches are more suitable. For example, outdoor LED billboards often use P5, P8, or P10 pixel pitches, because viewers often watch from tens of meters or more away. Large pixel pitches not only save on display production and maintenance costs, but also reduce power consumption, making them suitable for large-screen applications.

The optimal viewing distance also plays an important role in choosing the right pixel pitch. This is the distance at which the viewer can experience the clearest image without distortion or visible pixels. Generally, the smaller the pixel pitch, the closer the optimal viewing distance. Determining this distance correctly helps optimize the viewing experience.

Therefore, choosing the right pixel pitch is a key factor when using LED displays. Whether it is to display sharp images at close range or to create a large, cost-effective display for distant audiences, choosing the right pixel pitch is extremely important.

How does pixel pitch affect image quality?

Pixel pitch plays an important role in image quality because it determines the resolution and affects the optimal viewing distance of the LED screen. The smaller the pixel pitch, the higher the resolution, making the image more detailed and sharp. Therefore, if you need to display high-quality images or videos, you should choose an LED screen with a small pixel pitch.

Pixel pitch also affects viewing distance. High resolution and clear images allow viewers to stand closer to the screen. However, close viewing depends on whether the LED screen is used indoors or outdoors. For indoor LED screens, small pixel pitch allows viewers to come closer to see details clearly. For outdoor LED screens, due to the high brightness of the LEDs, standing too close can cause glare. Therefore, the choice of pixel pitch should be based on whether it is used indoors or outdoors to ensure the best experience.
