Abstract
Mini‐LED products are currently attracting the attention of the consumer market. It can achieve high dynamic contrast ratio through local dimming algorithm. Compared with traditional backlight and OLED, Mini‐LED products have the advantages of low power consumption, high brightness, long life‐time and high reliability. However, due to the LED distribution and disproportional dimension deviation of Mini‐LED light board, edge strip mura and difficult die bonding may sabotage overall display performance and production yield. To solve these problems, this paper proposes LED gradient distribution theory and reference quadrilateral stacking parameters to enhance the competitiveness of Mini‐LED core products.
