Description

Novel EDP physics switching structure

Technical Field

The utility model relates to the technical field of EDP signal transmission, in particular to a novel EDP physical switching structure.

Background

The EDP interface is a fully digital interface based on DisplayPort architecture and protocol, can use simpler connectors and fewer pins to transmit high-resolution signals, and can realize simultaneous transmission of multiple data, so its transmission rate is much higher than LVDS. The EDP interface is also a communication interface commonly used for the lcd, and the lcd generally using the EDP interface has a higher resolution.

At present, industrial personal computers, all-in-one reinforcing machines, notebook reinforcing machines and the like in the market mostly use display screens of LVDS interfaces, the LVDS interfaces transmit data through difference, namely low-voltage differential signal transmission, the defects of high power consumption, high EMI electromagnetic interference and the like when broadband high-code-rate data are transmitted in a TTL level mode are overcome, signals can be transmitted on differential PCBs or differential cables at high speed, and low noise and low power consumption are realized due to the adoption of low-voltage and current driving modes. However, with the development of the liquid crystal display technology, the liquid crystal display with high resolution is more and more favored by the market, if the LVDS interface is adopted, the number of the required data transmission lines is more, and for example, a liquid crystal display screen with resolution of 1920 × 1200 and 24bit colors needs 20 pairs of the LVDS interface data transmission lines; if EDP is used, only 4 pairs of lines are needed, from which it follows that the advantages of EDP interface are quite significant, especially in high definition.

In recent years, in order to increase the data transmission speed between a panel and a processor and obtain better use experience, high-definition liquid crystal screens with EDP interfaces are widely used in industrial personal computers and industrial tablet computers. However, the liquid crystal screen of the EDP interface generally uses a 0.3-0.5mm small-spacing welding type flat coaxial line, and the main board and the liquid crystal screen are displayed in the same installation space in an industrial personal computer or a tablet personal computer, so that wiring and installation are convenient; when EDP signal transmission is carried out between different installation spaces such as a reinforced notebook or a reinforced all-in-one machine, the existing flat cable cannot meet the use requirement due to the limitation of inconvenient perforation or bending and the like.
