As technology continues to get smaller and get more functionality, cable technology should also adapt to keep up. eDp cables are a good example of this quickly changing world of technology. Embedded DisplayPort (typically called eDP) is based on the VESA DisplayPort Standard. Embedded DisplayPort is a high end audio/visual interface developed through the personal computer industry which allows displays to display in 4k and beyond. eDP cables have become a well known replacement for LVDS display cables which have been the standard since the mid 1990s.
Advantages and Common Uses of eDP Cables – What are some of the features of eDP Cable over other models so when are they very useful? This is a brief breakdown to give you a wise idea if eDP cables are right for any project.
eDP Cable Advantages: Small compared to similar cable varieties; Require fewer connections than LVDS assemblies; All power, data, and control through a single assembly; eDP Cable Common Uses; Laptops; Pcs and HD Displays (monitors, TVs, etc.)
The Video Electronics Standards Association (VESA) first released the Embedded DisplayPort (eDP) standard during 2009 as an extension in the DisplayPort standard to be used with embedded displays. VESA developed eDP to switch the aging Low-Voltage Differential Signaling (LVDS) standard, and today eDP can be used widely in notebook computers and all-in-one systems. The primary benefits associated with eDP over LVDS range from the decrease in signal wires due to its higher data rate, compatibility with submicron chip processes, decreased interference with wireless services, and being able to accommodate new features.
Since its initial release the eDP standard went through a number of revisions adding new features not distributed to DisplayPort, as eDP has changed to target battery-operated embedded display systems. As an example, during 2010 eDP version 1.2 was published, adding control of display and backlight features over the auxiliary channel. This Year eDP version 1.3 introduced Panel Self Refresh (PSR).
While eDP was originally intended for notebooks and all of-in-one systems, it really is 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 designed to address this broader variety of form factors and additional reduce system power.
The significance of lowering display-related system power – Today, cellular devices are a major driving force within the electronics industry. Each year new mobile devices are introduced with additional processing capability, better displays, a lesser and lighter form factor, and extended battery life. Considering typical CPU idle time, a typical 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 second-generation iPad had a 1024×768 display along with a 25 watt-hour battery, while the latest iPod includes a 2048×1536 display (a 400 percent pixel increase) and a 42.5 watt-hour battery (a 70 % power increase), both delivering a 10-hour battery lifespan. The larger-resolution display requires additional pixel-driving circuitry along with a higher data rate display interface, in addition to faster Graphics Processing Unit (GPU) rendering and display image processing circuitry.
This display power challenge has resulted in many new architectural developments on the platform level. Reducing display power means longer life of the battery and less battery capacity requirement and thus smaller, lighter, and less expensive systems. Instead of being treated being a simple rendering device, display deployment has grown to be more incorporated into the general system design. The newest eDP v1.4 brings many of these concepts together, as explained inside the following discussion.
