As technology continues to get smaller and get more functionality, cable technology must also adapt so as to keep up. eDp cables are an example of this quickly changing world of technology. Embedded DisplayPort (typically called eDP) is based on the VESA DisplayPort Standard. Embedded DisplayPort is actually a high end audio/visual interface developed through the pc industry which allows displays to display in 4k and beyond. eDP cables are becoming a popular replacement for LVDS display cables that have been the standard since the mid 1990s.
Advantages and Common Uses of eDP Cables – What are the features of eDP Cable over other models and once are they best? This is a brief breakdown to provide you with a good idea if eDP cables are suitable for any project.
eDP Cable Advantages: Small compared to similar cable varieties; Require fewer connections than LVDS assemblies; All power, data, and control through one single assembly; eDP Cable Common Uses; Laptops; Computers and HD Displays (monitors, TVs, etc.)
The Recording Electronics Standards Association (VESA) first released the Embedded DisplayPort (eDP) standard in 2009 as being an extension in the DisplayPort standard to use with embedded displays. VESA developed eDP to change the aging Low-Voltage Differential Signaling (LVDS) standard, and today eDP is utilized widely in notebook computers and all sorts of-in-one systems. The key advantages of eDP over LVDS are the decrease in signal wires because of its higher data rate, compatibility with submicron chip processes, decreased interference with wireless services, and its ability to accommodate additional features.
Since its initial release the eDP standard has gone through a series of revisions adding additional features not shared with DisplayPort, as eDP has evolved to focus on battery-operated embedded display systems. As an example, during 2010 eDP version 1.2 was published, adding control of display and backlight features within the auxiliary channel. In The Year 2011 eDP version 1.3 introduced Panel Self Refresh (PSR).
While eDP was originally intended for notebooks and all-in-one systems, it is actually becoming more and more optimized for smaller form factor systems including tablet and PC smartphone applications. Released in December 2012, eDP version 1.4 adds new optional features developed to address this broader selection of form factors and additional reduce system power.
The importance of lowering display-related system power – Today, mobile devices are a major power inside the electronics industry. Every year new mobile devices are introduced with additional processing capability, better displays, a reduced and lighter form factor, and extended battery lifespan. Taking into consideration typical CPU idle time, an average display consumes about 75 percent of system power. While system chip power reduction is accomplished through shrinking semiconductor process geometries, display tmcaao reduction comes through improvements in backlight and LCD technologies, along with new pixel structures.
However, the current trend toward brighter, higher-resolution displays is driving up display power. The next-generation iPad enjoyed a 1024×768 display as well as a 25 watt-hour battery, while the latest iPod features a 2048×1536 display (a 400 percent pixel increase) as well as a 42.5 watt-hour battery (a 70 % power increase), both delivering a 10-hour life of the battery. The greater-resolution display requires additional pixel-driving circuitry along with a higher data rate display interface, along with faster Graphics Processing Unit (GPU) rendering and display image processing circuitry.
This display power challenge has led to many new architectural developments at the platform level. Reducing display power means longer life of the battery and less battery capacity requirement and for that reason smaller, lighter, and much less expensive systems. Rather than receiving treatment being a simple rendering device, display deployment has become more integrated into the general system design. The new eDP v1.4 brings most of these concepts together, as explained in the following discussion.
