As technology continues to get smaller and get more functionality, cable technology must also adapt so as to keep up. eDp cables are an illustration of this this quickly changing world of technology. Embedded DisplayPort (known as eDP) is based on the VESA DisplayPort Standard. Embedded DisplayPort is a high performance audio/visual interface developed through the computer industry that allows displays to display in 4k and beyond. eDP cables are becoming 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 among the benefits of LVDS Cable over other models and when will they be very useful? This is a brief breakdown to offer you a good idea if eDP cables are appropriate for your project.
eDP Cable Advantages: Smaller than 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 of the DisplayPort standard to be used with embedded displays. VESA developed eDP to replace the aging Low-Voltage Differential Signaling (LVDS) standard, now eDP is utilized widely in notebook computers and all sorts of-in-one systems. The primary advantages of eDP over LVDS range from the lowering of signal wires due to its higher data rate, compatibility with submicron chip processes, decreased interference with wireless services, and being able to accommodate extra features.
Since its initial release the eDP standard has gone through several revisions adding new features not distributed to DisplayPort, as eDP has evolved to concentrate on battery-operated embedded display systems. For example, during 2010 eDP version 1.2 was published, adding charge of display and backlight features on 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 is becoming more and more optimized for smaller form factor systems including tablet and PC smart phone applications. Released in December 2012, eDP version 1.4 adds new optional features designed to address this broader variety of form factors and further reduce system power.
The significance of lowering display-related system power – Today, mobile phones certainly are a major power inside the electronics industry. Each and every year new mobile devices are introduced with additional processing capability, better displays, a lesser and lighter form factor, and extended battery life. Taking into account typical CPU idle time, the 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, in addition to new pixel structures.
However, the recent trend toward brighter, higher-resolution displays is driving up display power. The next-generation iPad had a 1024×768 display and a 25 watt-hour battery, as the latest iPod features a 2048×1536 display (a 400 percent pixel increase) and a 42.5 watt-hour battery (a 70 percent power increase), both delivering a 10-hour battery lifespan. The higher-resolution display requires additional pixel-driving circuitry and a higher data rate display interface, as well as faster Graphics Processing Unit (GPU) rendering and display image processing circuitry.
This display power challenge has led to many new architectural developments on the platform level. Reducing display power means longer battery life and less battery capacity requirement and for that reason smaller, lighter, and much less expensive systems. Instead of receiving treatment as a simple rendering device, display deployment is becoming more integrated into the general system design. The brand new eDP v1.4 brings most of these concepts together, as explained inside the following discussion.
