As technology continues to get smaller and get more functionality, cable technology should also adapt in order to keep up. eDp cables are a good example of this quickly changing world of technology. Embedded DisplayPort (commonly referred to as eDP) is based on the VESA DisplayPort Standard. Embedded DisplayPort is actually a good performance audio/visual interface developed through the pc industry that enables displays to display in 4k and beyond. eDP cables have grown to be a well known alternative to LVDS display cables that have been the standard since the mid 1990s.
Advantages and Common Uses of eDP Cables – What are some of the features of Micro Coaxial Cable Assembly over other models and once will they be most useful? This is a brief breakdown to offer you 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 assembly; eDP Cable Common Uses; Laptops; Computers and HD Displays (monitors, TVs, etc.)
The Video Electronics Standards Association (VESA) first released the Embedded DisplayPort (eDP) standard during 2009 being an extension of the DisplayPort standard to be used with embedded displays. VESA developed eDP to switch the aging Low-Voltage Differential Signaling (LVDS) standard, and now eDP can be used widely in notebook computers and all of-in-one systems. The key advantages of 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 its ability to accommodate extra features.
Since its initial release the eDP standard has gone through a series of revisions adding new features not shared with DisplayPort, as eDP has changed to target battery-operated embedded display systems. For example, during 2010 eDP version 1.2 was published, adding charge of display and backlight features over the auxiliary channel. In The Year 2011 eDP version 1.3 introduced Panel Self Refresh (PSR).
While eDP was originally created 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 developed to address this broader range of form factors and further reduce system power.
The value of lowering display-related system power – Today, mobile devices are a major motivator within the electronics industry. Each and every year new mobile devices are introduced with increased processing capability, better displays, a reduced and lighter form factor, and extended life of the battery. Considering 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, as the latest iPod includes a 2048×1536 display (a 400 percent pixel increase) along with a 42.5 watt-hour battery (a 70 percent power increase), both delivering a 10-hour battery life. The larger-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 in the platform level. Reducing display power means longer battery lifespan and much less battery capacity requirement and for that reason smaller, lighter, and less expensive systems. Rather than being treated as a simple rendering device, display deployment has grown to be more incorporated into the general system design. The new eDP v1.4 brings many of these concepts together, as explained in the following discussion.
