Abstract

The invention discloses a microscopic dendritic structure model, an optimizing method thereof, a thin film and a grating with the same. According to the method, a microscopic dendritic structure is optimized by utilizing a particle swarm optimization algorithm and taking a blue flash wing structure as a model to obtain a relatively good staggered and layered structure. The structural model provided by the invention is simple; by using the elements such as the grating and the thin film with the structural model, a wide viewing angle effect can be achieved efficiently; and the thin film provided with the structural model is arranged in a light emitting diode (LED) lamp, so that a light source is fully utilized, and a very good vision field effect is achieved.

Description

technical field [0001] The invention relates to the field of optics, in particular to a microscopic dendritic structure model and its optimization method, its thin film and its grating. Background technique [0002] With the development of digital TV technology, liquid crystal display has gradually become the mainstream product of digital TV terminal display equipment due to its small and exquisite appearance, ultra-thin body, low power consumption and light weight. However, the narrow viewing angle of liquid crystal display has become a major obstacle to its development. The root cause of this problem lies in the physical characteristics of liquid crystal and the physical structure of the display. The commonly used wide viewing angle technologies are multi-domain vertical orientation wide viewing angle technology, continuous firework-like arrangement mode wide viewing angle technology and OCB wide viewing angle technology, but these commonly used technologies are relatively...
