Abstract

The invention discloses a backlight assembly which comprises a back board, frames and connecting pieces. A reflecting piece, a backlight LED light source, an acrylic light guide plate (PMMA) and an optical membrane are sequentially arranged on the back board from bottom to top. The back board is made of tempered glass, and the section of the back board is arc; the frames are made of aluminum alloy and comprise horizontal frames and vertical frames. The horizontal frames are provided with U-shaped grooves matched with the horizontal edges of the back board, the vertical frames are provided with U-shaped grooves matched with the vertical edges of the back board, and the back board is mounted in a quadrilateral U-shaped groove framework formed by the two horizontal frames and the two vertical frames. The horizontal frames and the vertical frames are connected through the connecting pieces. The backlight assembly has the advantages of a steel plate backlight assembly and a plastic backlight assembly, the process is simple, cost is low, the back board is high in hardness, and the cost performance is high; the backlight assembly is simple in structure, convenient to assemble, good in universality and capable of being widely applied to liquid crystal displayers and liquid crystal television products, especially curved-surface liquid crystal displayers and curved-surface liquid crystal television products.

Description

technical field [0001] The invention relates to the technical field of backlight inside a television, in particular to a backlight assembly. Background technique [0002] With the development of science and technology, the liquid crystal display technology is becoming more and more mature, and the TV has changed from the traditional picture tube to the current liquid crystal display. The display screens in small-size LCD TVs account for a high proportion of the overall value, especially in commercial models, which are becoming more and more widely used. At present, there are large-scale curved LCD TVs on the market, because they can provide wider viewing angles and panoramic images when people watch large-size screens, and have better display images than ordinary flat-panel displays. favored by consumers. However, some bumps and bumps are unavoidable during the actual use of consumers. Due to its large area and curved surface structure, it is easy to be damaged. This is be...
