LED Display Quality Control

About us

Incoming Materials Check(IQC)

A “0” defectiveness product is realized starting from ideal raw materials. YVLED safeguard our displays’ quality starting from raw materials suppliers. Stay in workshops since the beginning, our egineer staff is experienced to supervise the craftmanship, ensure selected materials be adopted to cabinet frame, modules bracket, work out timely error correction solution, ensure each output is fully qualified.

Prototype Testify

Prototype testify is the only way to define the parameter to the displays, such as the current, RGBW brightness, heat-conducting. It is also the scientific way to verify the quality and performance of the final completed display. Through our setup and commissioning to the prototype, we can inject the best visual gene to display. Only a quality passed prototype can step into the SOP.
