Detection device for LCD connector of mobile communication terminal

Abstract

The invention relates to the technology of self-checking whether the connector of the LCD board of the mobile communication terminal such as a mobile phone falls off from the main board and notifying the user. The above-mentioned present invention includes a connector inspection section and a central processing unit, wherein the above-mentioned connector inspection section inspects the electrical contacts arranged at the four corners of the connector of the motherboard and the four corners of the connector of the LCD board, and judges whether the connectors are connected according to the inspection results. Normal; if the central processing unit determines that the connection between the connector on the motherboard and the connector on the LCD board is abnormal according to the connector inspection signal input by the connector inspection unit, it will notify the user or the PC of the judgment result.

Description

technical field [0001] The invention relates to a technology for self-checking whether the connector of the LCD board of a mobile communication terminal such as a mobile phone has fallen off from the main board and notifying the user, in particular, a terminal self-checking whether the connecting pin of the connector between the LCD board and the main board is normal Connect, and report the result to the LCD connector inspection device of the user's mobile communication terminal. Background technique [0002] Recently, the penetration rate of mobile phones has risen rapidly and has become a necessity of modern life. In addition to providing traditional voice services, mobile phones also provide various data transmission services and additional services, so they can be called multimedia communication devices in terms of function. [0003] As a result, end users are using LCDs more than ever before. However, if the user accidentally drops or is subject to a violent external i...

AI Technical Summary

Problems solved by technology

However, if the user accidentally drops or is subject to a violent external impact during the use of the terminal, there will often be a problem that the connector between the main board and the LCD board cannot maintain a normal connection state, resulting in the LCD not working normally. or simply not working

[0004] Because existing mobile communication terminals do not have the function of self-checking the connection status of the connector between the motherboard and the LCD module and notifying the user, if the LCD does not work normally, the user will feel alarmed, thereby reducing the need for products. reliability
