Mini-LED backlight module and display device

Abstract

The invention discloses a Mini-LED backlight module which comprises a back plate and a lamp panel laid on the back plate, and the lamp panel comprises a plurality of lamp panel single bodies arrangedin a butt joint mode. Reflecting pieces are laid on the lamp panels, and the reflecting pieces are arranged at the splicing positions of every two adjacent lamp panel single bodies in a folded mode. According to the Mini-LED backlight module, due to the fact that the reflector plates at the splicing positions of the adjacent lamp panel single bodies are designed to be folded, even if the lamp panel single bodies are slightly deformed due to transportation and other reasons, the folded parts of the reflector plates can well move along with deformation of the lamp panel single bodies; therefore,irreversible damage to the reflector plate caused by deformation of the abutted seams of the lamp panel single bodies is avoided, quality of the reflector plate is guaranteed, and the service life ofthe reflector plate is prolonged. The invention further discloses a display device with the Mini-LED backlight module, and the display device also has the above technical effects.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display equipment, and more specifically, relates to a Mini-LED backlight module and a display device. Background technique [0002] With the emergence of liquid crystal display devices equipped with Mini LED backlights, the development of Mini-LED backlight modules has gradually become a new focus of liquid crystal display device manufacturers. The high contrast ratio greatly reduces the power consumption of the TV; the maximum brightness can reach 1000nit, and at the same time, it matches the quantum dot technology to achieve a high color gamut. [0003] The number of LEDs in the Mini-LED backlight area reaches thousands or even tens of thousands. Due to the limitation of the proofing machine, the mini-LED products are all small-sized light panels, and then the small-sized light panels are spliced ​​into large-sized backlights. There is usually a gap of a few millimeters between ...

AI Technical Summary

Problems solved by technology

[0004] However, if the reflector is applied in the above-mentioned way, in environmental experiments and mechanical experiments, due to thermal expansion and contraction and mechanical vibration, the seam spacing will inevitably change, resulting in irreversible damage such as deformation or even damage to the reflector above the lamp board, resulting in lamp Reduced optical taste at board splices

[0005] To sum up, how to effectively solve the problem that the reflector of the Mini-LED backlight module is easily damaged at the seam of the light board is a problem that those skilled in the art need to solve.
