In recent years, due to the changes in the upstream screen resources of the TV industry, the design of the appearance of the previous TV has been innovated, and two changes have been brought about: the change from the shell design to the integrated design of the module structure and the shell, and the change from plastic materials The design is transformed into a metal material. When it comes to metal materials, aluminum profiles are widely used in the middle frames, decorative parts, front shells and bases of the current TV industry because of their many advantages, and become the mainstream metal aluminum alloy application form.
At the 2012 CES show, South Korea’s LG exhibited the world’s first borderless TV LM9600, which uses a metal bending middle frame to attract a large number of visitors. Since then, LG has simultaneously opened up the entire screen resources of the ART3 and ART5 series, and has also opened a new direction for the appearance design of the TV industry.
Because the middle frame of the ultra-narrow, borderless TV is bent from aluminum, if the decorative parts use the same metal material, it can avoid the problems of large assembly gaps caused by injection molding decorative parts. Therefore, the material of the lower frame of the TV also changes from plastic to aluminum The transformation of profile transition.
Non-marking bending process, that is, after the aluminum profile is formed and bent, there is no bending gap between the front and side of the frame. The non-marking bending process adopted by the Yi TVslim 8800 has absorbed the sweat of the research and development team, and the frame is made to the extreme 7.8mm, and the thinnest part of the body is 12.8mm. In addition, the non-marking bending of the front shell assembly process is more advanced, and the labor cost and loss are lower than before.
With the evolution of ultra-narrow and ultra-thin TVs, the base aside from the clumsy plastic shape of the past, the light and strong base has become the finishing touch of the TV design. In 2013, SONY took the lead in launching a small-size modular all-in-one machine, equipped with a low-cost aluminum profile bending base, and optimized the combination of process and cost through clever design. In the follow-up, a number of large-section aluminum double-leg bases have been launched, which has set off a trend of new base materials.
