Description

[Technical field]

[0001] The invention relates to the field of electronic technology, and in particular to a shell for blocking an LCD and an antenna. [Background technology]

[0002] LCD (Liquid Crystal Display) is a liquid crystal display. The structure of LCD is to place a liquid crystal box between two parallel glass substrates, set TFT (thin film transistor) on the lower substrate glass, and set color filter on the upper substrate glass. The signal and voltage on the TFT are changed to control the rotation direction of the liquid crystal molecules, so as to control whether the polarized light of each pixel is emitted or not to achieve the display purpose.

[0003] Absorbing materials refer to a type of material that can absorb or significantly reduce the electromagnetic wave energy received on its surface, thereby reducing the interference of electromagnetic waves. In engineering applications, in addition to requiring the absorbing material to have a high absorption rate of electromagnetic waves in a wider frequency band, it is also required to have properties such as light weight, temperature resistance, moisture resistance, and corrosion resistance.

[0004] At present, the antenna used in the workshop is designed to be inside the cover plate covering the LCD. The antenna combination is attached to the cover plate, and the built-in area of ​​the antenna is generally attached to the battery cover or next to it. Since the antenna is attached to the battery cover or next to it, when the battery runs for a long time and generates high temperature, it is easy to cause the antenna performance to deteriorate. In addition, the antenna wiring position is inside the cover plate covering the LCD, and the antenna is in contact with the LCD. When the LCD is running, the antenna and the LCD are easy to interfere with each other and generate a large amount of electromagnetic waves, which in turn affects the operating efficiency of the antenna, and the antenna and the LCD cannot be blocked. Among them, the electromagnetic waves generated by the antenna and the LCD require a large amount of absorbing materials, and a large amount of aluminum foil and copper foil are also used in the process of attaching the antenna. Therefore, it will lead to an increase in production costs.

[0005] In view of this, it is necessary to provide a shell that blocks the LCD and the antenna to solve the problems of reduced antenna performance, interference between the antenna and the LCD, inability to block the LCD and the antenna, and increased production costs caused by the above-mentioned antenna design inside the cover covering the LCD.

[0010] A plurality of connecting members are respectively arranged on the sides of the step structure, a plurality of positioning holes are arranged on the connecting members, a hollow member is also arranged on the outer side of the base plate, and a hollow groove is arranged on the hollow member.

[0011] Optionally, the upper surface of the substrate matches the size of a display panel on the LCD.

[0012] Optionally, the hollow piece passes through the stepped structure so that the hollow groove is located on one side of the substrate, and the antenna passes through the hollow groove to connect to the LCD.

[0016] Optionally, the positioning holes on the connecting member cooperate with screws to clamp and fix the entire housing that blocks the LCD and the antenna.

[0017] Optionally, when the display panel on the LCD is snap-fitted and fixed on the substrate, the upper surface of the display panel and the surface where the connecting member is located are in the same plane.

[0033] The upper surface of the substrate 110 matches the size of the display panel on the LCD.

[0034] The hollow piece 150 penetrates the stepped structure 120 , so that the hollow groove 160 is located at one side of the substrate 110 , and the antenna passes through the hollow groove 160 to connect with the LCD.

[0035] The height of the stepped structure 120 is greater than the height of the substrate 110 , and the height of the connecting member 140 is greater than the height of the stepped structure 120 .

[0036] The substrate 110 is a rectangular substrate, and the substrate 110 cooperates with the stepped structure 120 to form a U-shaped substrate.
