In the field of PCBs used for MiniLED, WellCircuits has a relatively strong technological level in aspects such as finished product size, lamp bead size, yellowing value, reflectivity, and shrinkage rate. It has successfully developed a large-size production printing technology that can stably control the thickness of white oil printing within a narrow parameter condition window, improving the display effects such as dynamic contrast and brightness of terminal display screens. This technology can be applied to ultra-large screens and has a relatively strong technical advantage.

LED has two applications in display technology, one is backlighting and the other is direct display. According to display precision, it can be divided into small – pitch LED, Mini LED and MicroLED. As Mini LED direct – display is implemented in more application scenarios, Mini backlighting is also gaining more and more recognition in fields such as televisions, e – sports monitors, laptops and vehicles.
