Product Introduction and Process Features

MiniLED backlight refers to using MiniLED as the backlight for LCD panels. By setting up 
a large number of Mini LED chips in the backlight module, it achieves ultra-high contrast, 
ultra-high brightness, and ultra-high color gamut image quality performance. Simply put, it 
means replacing thousands of MiniLED chips with several large LED backlights, so TVs 
with MiniLED backlights have high brightness and contrast
