Problems solved by technology

[0004] At present, the direct-lit backlight still has the problem of high halo effect. The traditional method to solve this problem is to divide the number of LEDs in the optimal area, but this method will undoubtedly reduce the overall brightness of the backlight module, and because the LED has an optimal The range of driving current density, while the size of Mini-LED is small, the driving is limited, and regional dimming is required to make up for the problem of low luminous efficiency

Abstract

The invention relates to a Mini-LED through-hole dimming structure backlight and a manufacturing method thereof, comprising more than one light-emitting unit, each light-emitting unit including an electrode substrate, a Mini-LED, and a through-hole with a high-efficiency reflective film attached to the inner wall structure, diffusion plate and quantum dot film; the Mini-LED is arranged on the electrode substrate, the through-hole structure is also arranged on the electrode substrate, and is covered around the Mini-LED; the diffusion plate includes a rectangular part and The inverted tapered part is arranged in the through-hole structure, and the rectangular part is located on the top of the inverted tapered part and arranged on the upper end of the through-hole structure; the quantum dot film is arranged on the top of the diffusion plate. The invention can increase the number of coupled light rays and improve the brightness of the entire coupled light output area, which not only achieves the effect of uniform light output but also maintains the brightness.

Description

technical field [0001] The invention relates to the technical field of Mini-LED backlight design, in particular to a Mini-LED through-hole dimming structure backlight and a manufacturing method thereof. Background technique [0002] At present, LCD with LED backlight still occupies a dominant position in the market. Despite the emergence of OLED new technology, LCD TVs will still be the mainstream at present and in the next few years due to their fine resolution, mature production technology and popular prices. As a passive light-emitting display device, it is difficult to improve its light source utilization efficiency and subjective image quality. With the demand promotion and technological development of the third-generation display, the submillimeter light-emitting diode (Mini-LED) display is formed by a high-density two-dimensional array of Mini-LEDs. Mini-LED is an all-solid-state active light-emitting device, which has the characteristics of low operating voltage, h...
