Micro LED and Mini LED are the latest generation of display technologies. Compared with traditional LED, mini LED has smaller size, shorter convergence distance, higher brightness and contrast, lower power consumption and longer service life. Micro LED has even higher brightness & contrast, higher resolution, better reliability, faster response time, lower power consumption. The technology requirement for the backlight PCB has become a huge challenge. Yue Wah Circuits Co., Ltd. has overcomed the challenge after investment in R&D and production line. Now these products are already in mass production to customers. With the success in LED backlight industries, this kind of PCB accounts for 45% of the company's sales share and has become the company's main product.
