P4 indoor LED module 256mm x 128mm

P4 indoor LED module refers to the pixel spacing of 4mm, that is, the distance between two-pixel dots. The center distance between the two LEDs of P4 is 4mm, and the picture is not distorted 4 meters away, that is, the lamps cannot be seen.

  • Pixel pitch: 4 mm;
  • Module size:256mmx128mm;
  • Weight: 175 g;
  • Module pixel: 2,048 pixel;
  • Lamps:SMD2121;
  • Viewing Angle:140 degree (V/H);
  • Scan: 1/16scan;
  • Density:62,500 dots/sqm;

P4 indoor full-color LED modules are usually used in hotel banquet halls, churches, and hotel stage background LED large screens. They can be used as temporary stage construction and LED stage large screens for performances and activities. It can also use cabinets spliced together in any size according to the site environment.

LED module aging test

LED module aging test is a reliability test to determine whether the LED module meets the standard, and the LED module also benefits from this rigorous test, which enhances its performance and stability module aging is an indispensable step in the production process of LED display, and it is also a testing link in the production and testing of LED display, and it is an important guarantee for the quality of LED electronic display products. The LED module aging test is a very important link in product quality control. LED products can improve their performance after aging, and help stabilize the performance for led display use.

LED module aging test, including red, green, blue, white, grid test, and video test, the aging time is more than 72 hours

LED module quality control

In order to ensure that customers can receive satisfactory products, we carry out strict quality control, testing, and reasonable packaging to protect the products from raw materials to production.

  • Incoming inspection and control of raw material lamp beads, IC, PCB, plastic, electronic components, etc;
  • Vibration test to detect whether the LED module has virtual soldering;
  • LED module aging test, detection of short circuit, virtual welding, component welding is correct, continuous tin, etc. for inspection and maintenance;
  • The waterproof test is to test whether the waterproof performance of the LED module and the box is qualified;
  • The whole led screen aging test, re-aging, and confirming whether the assembly process has secondary damage to the LED module, ensure that the products shipped to customers are OK products;
  • Reasonable protective packaging is a key factor in ensuring that high-quality products can reach customers normally.
