Abstract

The invention discloses a ruggedized computer display screen electromagnetic compatibility processing method, and belongs to the display screen electromagnetic compatibility processing technology field. The problems are solved that electromagnetic leakage is easy to cause and the electromagnetic shielding reliability is lowered during display screen electromagnetic compatibility processing. The technical scheme is as follows: a structural form combined with a liquid crystal screen front cover, an electromagnetic shielding conducting adhesive, a shielding silk screen and conductive foam is employed, and the method comprises the following steps: firstly, a boss is reserved in a position, where shielding glass is installed, of the liquid crystal screen front cover, and a square groove is processed on the boss; secondly, the shielding glass exposed from the shielding silk screen is fixed on the liquid crystal screen front cover by conductive double faced adhesive tapes, and the shielding and the boss are level; thirdly, the electromagnetic shielding conducting adhesive is painted inside the square groove; fourth, one side, with a binder, of the conductive foam is connected with the shielding silk screen, the shielding silk screen is pressed into the square groove in a manner of pressing the conductive foam, and after the electromagnetic shielding conducting adhesive is cured, tight contact of the shielding silk screen and the shielding glass is achieved.

Description

technical field [0001] The present invention relates to the technical field of electromagnetic compatibility processing of display screens, in particular to an electromagnetic compatibility processing method for strengthening computer display screens. Background technique [0002] With the increasing use of ruggedized computers in the military field, while the electrical performance and environmental adaptability continue to improve, electromagnetic compatibility has also received more and more attention. At present, almost all products have mandatory requirements for the electromagnetic compatibility of reinforced computers. sexual demands. The LCD screen module is an extremely important part of strengthening the computer's electromagnetic shielding. The display screen is exposed to electromagnetic pulses and has the largest opening area. If it is not handled properly, it will cause serious electromagnetic radiation. For the electromagnetic shielding of the LCD screen, the...
