Miniaturized display with electromagnetic shielding case

Abstract

The invention discloses a miniaturized display with an electromagnetic shielding case. The miniaturized display comprises a circuit main board formed through top-layer wiring and bottom-layer wiring, wherein the top wiring comprises a Scaler chip with a peripheral circuit, a Scaler chip supply circuit and an external signal interface; and an incoming resistor and incoming signal routing are connected in sequence between the external signal interface and the peripheral circuit of the Scaler chip. The miniaturized display is characterized in that the electromagnetic shielding case is arranged above the external signal interface, the incoming resistor and the incoming signal routing in a covering manner. The invention has the benefits that through the optimal design of high-speed signal and power supply signal routing in a PCB (Printed circuit board), only the external signal interface and an external signal incoming circuit are covered, so that the design of the shielding case is simplified, the area of the shielding case is greatly reduced and is about 40 percent of the original shielding case, and the production cost of the display is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a display with a miniaturized design of an electromagnetic shielding cover. Background technique [0002] With the continuous development of science and technology, household appliances such as computers, televisions, video cameras, and cameras are becoming more and more popular in people's daily life. People often use computers to understand outside information and to learn. Computers have become an indispensable part of people's lives. component. [0003] At present, most of the families are equipped with computers, by storing a large number of information files on the computer mainframe, and then displaying them on the monitor, so as to realize the purpose of allowing people to learn and use. [0004] However, when the display is working, it will generate electromagnetic radiation, which will cause harm to the human body. Therefore, various countries have formulated corresp...
