Application of aluminum alloy profiles on TV

In recent years, due to changes in the upstream screen resources of the television industry, the design of TV appearances has been reinvented, which has led to two changes: from the design of the housing to the one-piece design of the module structure and the housing, and from plastic materials. Transformed into a metallic material design. Regarding metal materials, aluminum profiles have been widely used in the middle frame, decorative parts, front shells, and bases of the television industry due to their numerous advantages, and have become the mainstream form of metal aluminum alloys.

First, the use of aluminum profiles in the middle frame

At CES 2012, South Korea’s LG exhibited the world’s first rimless TV, the LM9600, which uses a metal bent middle frame to attract the eyes of a large number of visitors. Since then, LG has opened the ART3, ART5 series of full-screen resources, and also opened up a new direction for TV industry design.

The entire ART3 main screen is based on the concept of “narrow border”, while ART5 is “no border” on the entire screen. Both require the use of a metal middle frame to protect the screen and conceal the side screw holes. Through practice, we have found that the use of aluminum forming after bending, can form a good strength, high precision, effective control and screen fit gap in the metal box, to meet our preset requirements.

The 8100 series is Konka's first ART3 screen TV. The middle frame is made of aluminum four-sided bending process, and the light-colored oxidation wire drawing process has low-key luxury that is in line with the public's aesthetic. Ever since its listing, Konka has repeatedly made sales of Konka's best high-end models.

The Konka 8300 series is a follow-up version of the 8100 series and is the second generation ultra-narrow frame ART3 TV. Through the unremitting efforts of Konka's design team, we have developed a mirror-plated level of polishing technology, and further upgraded the surface treatment of the aluminum frame. Such a dazzling appearance is nothing more than a tall television set designated by the Shenzhen Baoan New Airport.

The 9500 series is Konka's 2014 newest ART3 screen model. In the design of aluminum middle frame, the "step-by-step + double-surface treatment" process is used to visually separate the layers and achieve the effect of compressing the thickness of the complete machine.

Second, the use of aluminum profiles in decorative parts

Since the middle frame of the ultra-narrow, non-rimmed TV is aluminum bending, if the same metal material is used for the decorative parts, the problem of large assembly gaps caused by the injection molding decorative parts can be avoided, so the material of the lower frame of the television is also generated from plastic to aluminum. Transformation of the profile transition.

Konka's non-rimmed TV 9000 series is the first time to use aluminum decorative parts, which not only effectively protects and supports the borderless screen, but also perfectly connects with the aluminum frame in the side.

In addition to the mirror-grade polished middle frame, the Konka 8300 series is also simple and low-key, without losing the connotation. The designer drew on the subtle touch of the Ipad metal matte shell and transplanted the technology onto TV metal trims to make it soft and touchable.

Third, the use of aluminum profiles in the front shell

1, aluminum four sides splicing front shell

In recent years, the birth of the module-integrated machine has enabled domestic TV brand manufacturers to shift their purchase of upstream screen resources to the purchase of only the core component, screen glass, in order to increase the proportion of self-developed components and gain more profits.

The front shell of the module integrated machine adopts structural parts that are both appearance parts and fixed screen glass, and are often made of metal stamping parts, and there are problems such as less details change, high mold cost, and structural design limitations. At this time, the Konka 9800 series, which uses a four-sided aluminum profile to splicing the front shell, was born.

The 9800 series front shell adopts unique laser welding technology, which controls the splicing gap of four aluminum profiles below 0.1mm, and combines the high-bright cutting process of the frame to demonstrate the high-end flagship model's process quality. It is worth mentioning that the series of different sizes of the front shell adopts a uniform section profile, sharing a set of profile moulds, to reduce the cost of mold investment and material management, and greatly improve the yield and production efficiency. In this way, the R&D and production costs can be greatly optimized, and at the same time, the superb quality of the products can be ensured and the products are in an advantageous position in the market competition.

2, aluminum profiles without bending front frame

The industry continues to develop, technology continues to improve, and user experience continues to improve. Konka's TVslim8800 series carries the "narrower, thinner" user experience requirements, using domestic original metal aluminum profile seamless bending process, creating a dream model combining new technology and user experience.

No trace bending process, that is, after the aluminum profile is bent, there is no bending gap between the front and side of the frame. The traceless bending technology used by the TVslim8800 will meet the sweat of the R&D team. It will also create a border of 7.8mm and 12.8mm at the thinnest part of the fuselage. In addition, the assembly process of the front shell with no bending is more advanced, and it is lower than the previous labor cost and loss.

Fourth, the use of aluminum profiles in the base

With the evolution of ultra-narrow and ultra-thin TVs, the base has thrown away the awkward shape of plastic in the past, and the lightness and good supporting strength of the base has become the crowning touch of TV design. In 2013, SONY pioneered the introduction of a small-sized module integrated machine, equipped with a low-cost aluminum bending base, and optimized the combination of process and cost through clever design. Follow-up has also launched a number of large-profile aluminum profile feet base, set off a trend of new materials base.

1, aluminum bending base

The base of SONYW650A is a form designed by bending a small section of aluminum profile through a manufacturing device. The surface is simply sandblasted and oxidized, and then connected to the TV through an adapter bracket. The base design is simple and inexpensive, and it is a good example of application in the industry.

2, large-section aluminum two-foot base

SONYW850B's two-foot base is original, it uses a large section of aluminum extrusion, and then cutting, grinding, local CNC and subsequent oxidation processing. The advantages brought are obvious. First, the adapter bracket and the base are integrally formed to save the assembly process and increase the production capacity. Second, the compact size and the cost have advantages. Third, the stability of the large-size model is better.
