Problems solved by technology

[0004] However, in the related art, the shading frame is generally made by injection molding process, so the structural design of the shading frame needs to consider the manufacturing feasibility of the mold and the feasibility of injection mold release, so that the size design of the shading frame is limited, resulting in The shading effect of the frame is poor, which limits the optical performance of the LED display device using the shading frame

Abstract

The invention provides a shading frame and an LED display device. The shading frame comprises a blocking wall and a plurality of hollowed-out grids which are defined by the blocking wall and arrangedin a matrix mode. The blocking wall comprises the first blocking wall and the second blocking wall which are connected in an overlapped mode in the light emitting direction of the grids, and each gridcomprises a first grid part defined by the first blocking wall and a second grid part defined by the second blocking wall. The thickness of the first blocking wall is gradually reduced from one end close to the second blocking wall to one end far away from the second blocking wall to form a first draft angle; the thickness of the second blocking wall is gradually reduced from one end close to thefirst blocking wall to one end far away from the first blocking wall to form a second draft angle; and the thicknesses of the connecting positions of the first blocking wall and the second blocking wall are the same. Compared with like products in the prior art, the shading frame is excellent in shading performance, and the LED display device is excellent in optical display performance.

Description

【Technical field】 [0001] The invention relates to the field of optical projection equipment, in particular to a light-shielding frame and an LED display device. 【Background technique】 [0002] Optical large-screen display has gradually entered the field of high-quality video projection, and as the technology continues to mature, the application scenarios continue to expand. In practical application, the size of the optical large screen is relatively large, and it is generally formed by splicing multiple LED display devices. [0003] In the related art, each LED display device is used as a small unit of a large optical screen, and the LED display device includes a light-shielding frame, a light-transmitting film layer and an LED component installed on opposite sides of the light-shielding frame, and the LED component includes A plurality of LED lamp beads distributed in a matrix; the shading frame forms a plurality of grids distributed in a matrix and in a hollow structure, ...
