Description

Technical Field

[0001] This utility model relates to the field of television back panel technology, specifically to a plastic-metal composite liquid crystal module back panel structure. Background Technology

[0002] In the core structure of LCD displays, the LCD module backplate plays a crucial role. It not only provides stable and reliable support for the LCD panel and other internal components, ensuring precise installation and coordinated operation, but also significantly influences the heat dissipation performance, electromagnetic shielding effectiveness, and overall structural strength and stability of the LCD display. With the rapid development of display technology, consumers have placed increasingly stringent demands on LCD displays for thinner designs, higher performance, and longer lifespans. This has led to the growing popularity of plastic-metal composite LCD module backplates among manufacturers and users.

[0003] Existing plastic backplates are generally lightweight and easy to install and remove, but their load-bearing capacity is relatively weak, making them susceptible to damage and breakage due to external impacts and other accidents, and their rigidity is insufficient. While common metal backplates offer superior load-bearing capacity and rigidity, their heat dissipation is inadequate, and they are heavier and more expensive to manufacture. Furthermore, the combination of plastic and metal is relatively limited, failing to simultaneously achieve a good balance between lightweight design and high durability and load-bearing capacity. This results in less than ideal performance, insufficient ease of installation and removal, and generally poor heat dissipation and conductivity. Therefore, we propose a plastic-metal combined LCD module backplate structure to address these issues. Utility Model Content
