AI Technical Summary
In LCD TVs, mini-LED backlight beads dissipate poorly in the cavity formed by the metal back plate reinforcement ribs, resulting in reliability risks; at the same time, conventional LCD TVs require additional flame-retardant plastic back cover, which increases cost and installation complexity.
The metal back plate with integrated bent molding is equipped with a metal mounting plate and backlight source. The liquid crystal panel and optical diaphragm are fixed through decorative strips and bent parts, reducing the dependence on the additional back cover and simplifying the installation process.
The independent installation of the backlight source is realized, which avoids the impact of reinforcement ribs on heat dissipation, reduces material costs and installation complexity, and the product appearance is simple and easy to install.
