Flexible mini-LED backlight lamp panel and flexible electronic device thereof

Abstract

The invention provides a flexible mini-LED backlight lamp panel which does not need to be provided with a light guide plate, a diffusion film or a reflector plate. The backlight lamp panel comprises an FPC driving board and a mini-LED chip array electrically connected to the FPC driving board, and the mini-LED chip array is provided with a stack of at least three positive refractive index films with refractive indexes sequentially decreasing from bottom to top. According to the flexible mini-LED backlight lamp panel, the mini-LED chip array is provided with at least three stacked positive refractive index films of which the refractive indexes n1, n2 and n3 are sequentially decreased from bottom to top, the reflection light path and the light guide diffusion of the plane where the flexiblemini-LED backlight lamp panel is located are increased, the adjustable light equalization effect is achieved, the Mura lamp eye phenomenon is eliminated, and the light emitting uniformity and the light energy utilization efficiency of the area light source are improved.

Description

technical field

[0001] The invention relates to a display device, in particular to a flexible mini-LED backlight board and a flexible display electronic device thereof. Background technique

[0002] With the rapid development of display technology, people's demand for displays is getting higher and higher, especially for non-planar display devices such as flexible liquid crystal displays, curved liquid crystal displays, flexible liquid crystal displays and foldable liquid crystal displays. Flexible LCD panels are about to become the mainstream in the display field due to their thinness, bendability, and impact resistance. However, the liquid crystal display device is a non-self-luminous display device, which needs to be matched with a backlight to realize display, which greatly increases the difficulty of flexible display. How to realize flexible backlighting has always been a difficult problem to solve.

[0003] The direct-type backlight module is directly arranged behind...
