Abstract

The invention discloses a structure and design method for reducing the mixed light area of ​​Mini LED, which is used to solve the problem of light leakage and slight halo caused by the mixed light phenomenon in the Mini LED structure. Encapsulation: There is an arc-shaped convex cup on the convex-shaped sealant. The invention ensures that the surface of the colloid is in the state of an arc-shaped convex cup by controlling the package shape of the chip colloid, and uses the principle of concentrating light by a convex mirror to effectively reduce the projection on the module after the chip emits light. The generated area; through the optimization of the Mini LED dispensing technology and its structure, the convergence of light transmission is realized, and then the mutual independence of each single-particle light-emitting area is realized, the phenomenon of mixed light is reduced, and the delicate expression of the product screen display is finally realized, avoiding light Halo phenomenon, to achieve higher contrast.

Description

technical field [0001] The invention relates to the technical field of LED structures, in particular to a structure and a design method for reducing the mixed light area of ​​Mini LEDs. Background technique [0002] In the structure design of Mini LED, there will be a mixed light area between chips. When the spacing is small, due to light transmission, there will be a certain degree of mixing phenomenon in the light emitting area presented by the light source on the product. The smaller the spacing, the OD in the vertical direction The larger the value, the larger the space ratio of mixed light and overlap. The mixed light phenomenon will inevitably lead to discounting the significance of the Mini LED to achieve partition control through more partitions, or light leakage and slight halo phenomenon. [0003] By optimizing the Mini LED dispensing technology and its structure, the present invention realizes the convergence of light transmission, and then realizes the mutual in...
