Direct-type partition display backlight source

Abstract

The invention relates to the technical field of backlight sources, and particularly discloses a direct-type partition display backlight source. The direct-type partition display backlight source comprises a PCB bottom plate, a middle rubber shell, a light scattering film and a black-and-white single-sided adhesive which are assembled from bottom to top in a layering mode, preset regions are divided on the PCB bottom plate, each preset region is provided with an independent driving circuit and is uniformly provided with pipe cores in a distribution mode; the middle rubber shell comprises partition rubber shells which are correspondingly arranged in an isolated mode according to the preset regions. The direct-type partition display backlight source has the beneficial effects that the pipe cores are uniformly distributed on the preset regions on the PCB bottom plate, moreover, the middle rubber shell is arranged to be matched with the preset regions so as to realize partition display, moreover, each partition (preset region) is provided with the independent driving circuit, light with different colors can be emitted by the pipe cores in all the partitions, the middle rubber shell andthe PCB bottom plate are combined, then in addition, the middle rubber shell is divided in a cross-shaped mode, the periphery of the inner wall of each divided partition is provided with a certain gradient, then the direct-type structure is formed, and the utilization rate of light is improved.

Description

technical field [0001] The invention relates to the technical field of backlight sources, in particular to a direct-lit partitioned display backlight source. Background technique [0002] The light-emitting mode of conventional vehicle backlights is a side-emitting structure, which can meet the requirements of general backlights, but for customers with multi-functional requirements, the conventional side-emitting structure is far from meeting the needs of consumers, so the direct-type structure should be used However, the biggest feature of the direct-down structure is that the LED lights are at the bottom of the product, and the light source is emitted vertically from the bottom. The structure can meet the customer's functions of highlighting, narrow frame and partition display, and it is more in line with consumers' consumption concepts in real life. Contents of the invention [0003] The invention provides a direct-type partitioned display backlight, which solves the t...
