Problems solved by technology

[0004] However, when static electricity is introduced into the portable radio communication terminal through the LCD module or buttons protruding outward, the FPC electrically connecting the LCD module to the RF board does not fully ground the high-voltage static electricity on the order of several thousand volts
Thus, the resulting electrical shock of high voltage static electricity causes the radio communication terminal to malfunction

Embodiment Construction

[0012] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

[0013] figure 1 is a perspective view of a general portable radio communication terminal. see figure 1 , the portable radio communication terminal has a main body 100 including an upper housing frame 111 , a lower housing frame 112 , a speaker 120 , an LCD module 130 , a folding cover 140 , a microphone 150 and an antenna device 160 . The speaker 120 is used to output received sound information or audio data. The LCD module 130 is disposed under the speaker 120 to display input data. The folding cover 140 is rotatable relative to the main body 100 to protect a plurality of underlying key knobs (not shown), and to concentrate sound signals or audio data. The microphone 150 is disposed under the ...

Abstract

There is provided a grounding device to prevent an ESD (Electro-Static Discharge) in a portable radio terminal having a main body with an upper casing frame, a lower casing frame, an RF board mounted to the main body, and an FPC integrated with an LCD module by an electrical connection mounted on the RF board. At least one metal grounding portion is extended outwardly from the FPC and is electrically connected to the inner side surface of the main body on which a conductive material is coated to increase a grounding area when the FPC is mounted to the main body. Therefore, the ESD problem is solved by the utilization of at least one metal grounding portion.

Description

technical field [0001] The present invention mainly relates to a portable radio communication terminal, in particular to a grounding device, which prevents damage to the portable radio communication terminal due to high voltage caused by external static electricity. Background technique [0002] Portable radio communication terminals have become smaller and lighter to meet consumer needs, however, their functions have become more diverse and more complex. In addition to voice calls, portable radio communication terminals also play music, support TV (television) broadcasting, Internet browsing, and even function as digital cameras. In order to realize these functions, a display device having a large LCD (Liquid Crystal Display) module has been developed to display received data or incoming data. Therefore, the area required to place the LCD in the portable radio communication terminal increases. [0003] The use of a large LCD may cause high-volt...
