What is a LED small-pitch display screen?

LED small-pitch display screen refers to an LED display screen with a pixel pitch of less than 2.5mm, which is mainly used for indoor display. Common models include P2.5, P2.0, P1.9, P1.8, P1.6, P1.5, P1.4, P1.2, P1.0, P0.9, P0.8, P0.7, P0.6, etc., where P represents the pixel pitch. The pixel pitch is inversely proportional to the value. The lower the value, the smaller the pixel spacing, making the display more detailed.

Working principle

1 Light-emitting principle: LED small-pitch display screen uses the characteristics of semiconductor materials to generate light sources through solid light-emitting components (LED chips). When current passes through the LED chip, the positive and negative charge carriers in the semiconductor material undergo composite reflection, thereby generating photons, that is, light energy.

2 Pixel control: Each pixel point is driven by a control signal to achieve lighting and extinguishing. The control signal is encoded and decoded in a series of ways, and the signal is distributed to the driver chip of each pixel point. After the driver chip receives the corresponding control signal, it chooses whether to light up the pixel according to the level of the signal.

3 Display technology: The LED display screen with small pitch uses row-by-row scanning or column-by-column scanning to control the lighting and extinguishing of LEDs to form an image display. At the same time, through high refresh rate and modular design, higher picture quality and smoothness can be achieved. High refresh rate can reduce flickering and smearing during dynamic image display, while modular design facilitates maintenance and replacement of single faulty modules.

LED small pitch display screen achieves high-definition, high-brightness, high-contrast, and high-refresh rate display effects by optimizing manufacturing processes and display technologies, meeting various high-demand visual presentation needs. With its excellent performance and diverse advantages, it has been widely used in various fields and has gradually become a new standard in the field of display technology.
