What Is The LED Spacing?

Preface

In today's digital age, with the rapid development of LED display technology, LED fine pitch technology has also made significant progress, which is completely changing the way we watch and experience visual content. LED fine pitch display screens are becoming more and more popular in the field of high-end display, covering control rooms, conference rooms, commercial displays and home theaters. What is LED fine pitch? What is the reason for its popularity?

What is LED fine pitch?

LED fine pitch refers to products with extremely small midpoint spacing in LED display screens. The pixel pitch of traditional LED display screens usually exceeds P2.5, while small pitch LED is defined as a pixel pitch of P2 or less, including P1.8, P1.5, P1.2 or even lower.

"P" means "pitch", and the number behind it indicates the distance between the center points of two adjacent LED lamp beads in millimeters. P1.2 means that the distance between the center points of two adjacent LED lamp beads is 1.2 mm.

The main defects of LCD/PDP splicing display

Small spacing has a bright future

1.Continue to replace splicing products in special fields (DLP, LCD)(Military/Government/Transportation/Broadcasting/Culture)

2.Gradually penetrate the mid-to-high-end commercial display field. Market: corporate publicity/conferences, hotels, shopping malls...

3.The rise of LED small-pitch engineering channels. Enterprise channel layout including Highmight, brand + channel marketing model, complementary advantages, win-win situation;. The local resource advantage of the channel makes it easier to open up the market and sink the market; (provincial and prefecture-level professional integrators, regional integrators, industry integrators, system integrators...)

4.Recognition by the global display industry
DLP international giants: Barco, Christie, Mitsubishi;
LCD display giants: NEC, Samsung, Sony, Philips, have all deployed small pitch in the past two years;
Prove that it will become a mainstream display product in the future;
With the involvement of display giants, it will promote product expansion and accelerate the popularization of applications.

LED small pitch product features

Seamless splicing, complete picture

· Eliminate visual seams and enjoy a large, complete display screen;
· Pure black and white background, bright colors and clear picture levels;
· Unique black ink processing technology and high-precision correction system make the screen bright and uniform

Broadcast color gamut

· Adopt RGB three-primary color imaging technology to meet broadcast standards;
· After single-point brightness and color correction, the brightness and color of the screen are highly consistent;
· The color temperature can be adjusted from 2500-10000K;

Fast frame change speed, nanosecond response

Nanosecond display technology is used to shorten the frame change time of the LED display to an extremely short time, eliminating the tailing and ghosting phenomenon that occurs when LCD and projection process fast dynamic images;

Ultra-wide viewing angle display

Ultra-wide viewing angle display;
160 degrees of viewing angle from left to right and up to down;
No blind spots or color cast;
Larger display coverage area.

Extremely fast refresh screen without flickering

Independently developed high-end broadcast control system, supports ultra-high refresh rate output, and drives decoding to respond quickly;
The captured image is stable without ripples or flickering, and can handle dynamic display images with clear image edges and good dynamic expression

Low brightness and high gray lossless technology

The grayscale display is almost perfect at low brightness, and the picture layering and vividness are good;
More image details, no information loss

Precision control technology

Own mold processing equipment and production workshops to ensure that each display unit box is processed with high-standard mold-level processing to achieve seamless splicing;
The original module can be adjusted front and back, up and down, left and right to ensure the flatness between modules and between modules;

Lower maintenance costs

Compared with traditional screens, when a single-point failure occurs in LED small-pitch display, only a single pixel LED or a single module needs to be maintained;

LED small-pitch display units are ultra-thin in design, and the rear maintenance space is less than 0.8m;

LED small-pitch display units have low power and low temperature rise, and have low maintenance costs and long life when used for a long time.
