LED Display Seamless Splicing Technology

Introduction

With the continuous progress of science and technology and the advent of the digital era, LED display screens have been widely used in various fields and have become an indispensable tool for information display, advertising, conference display, entertainment performance, and other activities.

Its high brightness, high definition, wide viewing angle, and long life make the LED display increasingly prominent in the market.

However, in the application of large LED displays, especially when multiple screens need to be spliced to form a larger display area, the traditional splicing method often has obvious splicing gaps, which not only affects the coherence and aesthetics of the visual effect but may also have an adverse impact on the transmission and display effect of information.

Therefore, the emergence of seamless splicing technology has brought revolutionary changes to the application of LED displays.

1. Principle of LED display seamless splicing technology

1). Physical splicing and logical splicing

Physical splicing is to connect multiple LED displays directly with a bracket or frame. However, there may be obvious gaps in this way, which will affect the viewing effect. Logical splicing is through technical means to make multiple screens visually form a whole without gaps.

2). The core of seamless splicing technology

Seamless splicing technology is mainly used to visually integrate multiple LED displays perfectly. It contains the following key points:

  • Pixel-level alignment: Let the pixels of multiple screens align neatly so that it looks like a large screen.

  • Color correction: Adjust the color of each screen so that they look the same and there is no color difference.

  • Brightness uniformity: Ensure that the brightness of each screen is consistent, so that there will be no uneven brightness after splicing.

3). Steps to achieve seamless splicing

To achieve seamless splicing technology, you need to follow the following steps:

  • Screen selection and calibration:

First of all, you need to select the appropriate LED display according to your actual needs and calibrate it. The calibration process includes checking the pixel quality, color accuracy, brightness uniformity, and other screen indicators to ensure that each screen meets the requirements for seamless splicing.

  • Stitching design and layout:

Design the splicing scheme according to the actual needs and determine the position, angle, and connection mode of each screen. At the same time, it is also necessary to consider the transmission and distribution of signals to ensure that the signal can be transmitted accurately and stably to each screen.

  • Installation and debugging:

Install according to the splicing design and layout scheme to ensure that each screen can be stably and firmly fixed in the designated position. After the installation is completed, debug it, check whether the display effect of each screen is consistent, and fine-tune it if necessary until the best effect is achieved. Finally, the whole system is tested and verified to ensure that it can operate normally and meet the actual needs.

2. Key technologies of LED display seamless splicing technology

1). Pixel-level calibration technology

Pixel-level calibration technology is one of the core of LED display seamless splicing technology. It ensures that the pixels between adjacent screens can be accurately aligned during the splicing process to form a continuous and non-fracture display screen.

  • Pixel accuracy adjustment:

By accurately adjusting the pixels of each LED display to ensure that the pixels of the adjacent screen can accurately correspond when splicing so as to eliminate the sense of fracture caused by pixel misalignment.

  • Pixel dislocation correction:

During the splicing process, pixel misalignment may occur due to various reasons (such as installation errors, screen deformation, etc.). Pixel misalignment technology can detect and correct these dislocations to re-align the pixels.

2). Color management technology

Color management technology is essential to ensure the color consistency of the LED display after seamless splicing.

  • Color space matching:

There may be differences in color space between different LED displays. Color space matching technology can ensure that the colors displayed on different screens can be accurately presented in the same color space after splicing.

  • Color consistency optimization:

Through professional color correction equipment and software, the color of each LED display is calibrated and optimized so that it can present a consistent and accurate color effect after splicing.

3). Brightness and contrast control technology

Brightness and contrast control technology play an important role in improving the overall visual effect of the LED display after seamless splicing.

  • Brightness equalization technology:

Due to the possible differences in the brightness of different LED displays, the brightness equalization technology can automatically adjust the brightness of each screen to show a uniform brightness effect after splicing.

  • Contrast enhancement algorithm:

Contrast is one of the important factors affecting the display effect. The contrast enhancement algorithm can enhance the contrast of the image and make the picture clearer and more vivid by processing the image. In the seamless splicing of LED display, the contrast enhancement algorithm can further improve the overall visual effect after splicing.

3. Application scenarios of LED display seamless splicing technology
