Problems solved by technology

[0003] In the mini LED backlight, the traditional secondary lens structure is difficult to achieve thinning effect, and the traditional lens patch method also has high cost. In addition, if the same injection molding solution is used to realize the microlens array, it is also difficult to achieve large-area effect
In addition, on the mini LED lamp board, usually only the primary optical effect can be achieved (the air layer cannot be formed), and the secondary lens optical effect cannot be achieved

Abstract

The invention discloses a thin lamp panel and a manufacturing method thereof. The thin lamp panel comprises a lamp panel. A plurality of first structural bodies are arranged on one surface of the lamppanel. Each of the plurality of first structural bodies is provided with a notch and an accommodating groove, and a light source is arranged in each accommodating groove. The thin lamp panel furthercomprises a diaphragm. The diaphragm is arranged opposite to the lamp panel. A plurality of second structural bodies matched with the plurality of notches are arranged on one surface of the diaphragm.The first structural bodies and the second structural bodies are attached to form a secondary lens, so that light diffusion is achieved. Furthermore, when the light mixing height is achieved to be the same, the number of light sources is reduced. The cost is reduced. Meanwhile, the product thinning purpose is achieved.

Description

technical field [0001] The invention belongs to the field of backlights, and in particular relates to a thinned lamp board and a manufacturing method thereof. Background technique [0002] Mini LEDs are small in size and are used to realize ultra-thin multi-zone, which is the current development technology direction of the industry. However, when the mini-LED solution is applied to TV products, the thinning also brings a large number of mini-LEDs, resulting in high cost and difficult application in the current market. How to reduce the number of mini light-emitting diodes while maintaining the multi-zone effect and ultra-thin effect, so as to reduce the cost has become the development direction of the industry. In the past, the industry usually used a secondary lens to achieve light diffusion, thereby achieving the same light mixing height and reducing the number of mini LEDs. [0003] In the mini LED backlight, the traditional secondary lens structure is difficult to achi...
