After introducing all kinds of knowledge from LED lamp, LED modules, LED cabinets to LED display.
Now let me complement the basic knowledge for the LED lamp and LED modules.
When we talk about the LED module, we often hear the “P”. For example, P10, P6, etc. Here the “P” stands for pixel pitch.Now the big pixel pitch in LED module is P10 single color, double colors and full colors LED modules with SMD LED lamp and DIP LED lamp. What is the Pixel Pitch in LED screen? The pixel pitch also referred to as “dot pitch or pitch”, is a way of mearsureing pixel density, calculated as the distance from the center of a pixel to the center of the adjacent pixel on an LED display board and correlates with resolution. It is written in the form of “P” in millimeters.
The picture show the Pixel Pitch in DIP or SMD indoor or outdoor LED modules.
The LED display industry began from the DIP outdoor and indoor P10 single color LED module. Let me introduce the more details of DIP outdoor P10 red color LED modules. The waterproof level is IP 65 in front of LED modules because there is black color silicone or transparent glue in front of PCB with plastic lamp bead water mask in front of LED panel. There are surrounding guide channel and bottom drain holes in the black color plastic base in the outdoor DIP P10 red color LED module.
The picture is the other details outdoor DIP P10 red color LED module.
The DIP or SMD outdoor or indoor P10 single color LED panels connecting with LED power supply and controlling card in aluminium profile, which become a full simple or small LED sign, including circular LED stock ticker sign, variable speed limit LED signs or multi-language LED sign, and so on.
The main compartment in the LED lamp is LED chip. The quality of LED lamp is mainly decided by the quality of LED chip.The famous brands of LED chip include Cree from United States of America, Nichia made by Japanese company, Epistar from Chinese Taiwan. The biggest manufacturer of good quality of LED chip is from Sanan in Xiamen, China.The other main compartment of LED module is “IC”,also referred to as “driving IC”.The famous brand in the driving IC, including Toshiba from Japan, Allego from USA, MBI and TMS and Mingyang from Chinese Taiwan, Silan and Chipone in China, and so on.
What’s relation between pixel pitch and view distance in LED screen billboard? Much of the conversation around direct view LED display technology focuses on pixel pitch — how close together the tiny light pixels are placed on the displays. Matching pixel pitch to viewing distance delivers an optimal viewing experience and ensures that business partners and end users are getting the most value from their capital investments.In an interesting twist, right-sizing pixel pitch displays has everything to do with how far away the screen’s average viewers will be.
Here’s a rundown of what pixel pitch is all about and the relationship between pixel pitch and viewing distances. In one world, usually,one pixel pitch in LED modules is for one meter nearest viewing distance in LED billboard. For example, the nearest viwing distance for DIP or SMD P10 single color LED sign, SMD indoor or outdoor full color P10 LED screen display is 10 meters. The nearest viwing distance for P2.5 SMD full colors LED billboard is 2.5 meters.
The picture show the relationshipe between pixel pitch and viewing distance.
