Electrostatic discharge protection of MiniLED backlight units on glass

Active matrix (AM) MiniLED backlight units (BLU) on glass substrate is developed to solve severe problems of MiniLED on PCB including insufficient heat dissipation and worse swelling and shrinking performance, as well as limited zone number. However, the MiniLED on glass is observed to possess a weak ability of anti-electrostatic discharge (ESD). The MiniLEDs on glass developed by us (short for MLED) are demonstrated to have a powerful ability of anti-ESD by the means of optimization of peripheral circuit design and metal and dielectric materials, also by the improvements of surroundings of module assembly factory. Consequently, the failure ratio of reliability analysis of MLED is observed to be decreased drastically after the improvements of the ability of anti-ESD. (C) 2021 The Authors.
