As technology continues to get smaller and get more functionality, cable technology should also adapt so as to keep up. eDp cables are an illustration of this this quickly changing world of technology. Embedded DisplayPort (commonly referred to as eDP) is based on the VESA DisplayPort Standard. Embedded DisplayPort is a good performance audio/visual interface developed through the pc industry that allows displays to display in 4k and beyond. eDP cables have grown to be 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 advantages of Micro Coaxial Cable Assembly over other models so when will they be most useful? Listed here is a brief breakdown to give you a good idea if eDP cables are appropriate for your 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 as an extension of the DisplayPort standard to be used with embedded displays. VESA developed eDP to change the aging Low-Voltage Differential Signaling (LVDS) standard, and now eDP is utilized 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 capability to accommodate extra features.
Since its initial release the eDP standard has gone through a series of revisions adding extra features not distributed to DisplayPort, as eDP has changed to concentrate on battery-operated embedded display systems. As an example, in 2010 eDP version 1.2 was published, adding charge of display and backlight features within the auxiliary channel. This Year 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 increasingly 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 created to address this broader selection of form factors and further reduce system power.
The value of lowering display-related system power – Today, mobile devices are a major motivator inside the electronics industry. Each and every year new mobile phones are introduced with additional processing capability, better displays, a reduced and lighter form factor, and extended battery life. Taking into account 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, as well as new pixel structures.
However, the recent trend toward brighter, higher-resolution displays is driving up display power. The second-generation iPad enjoyed a 1024×768 display as well as a 25 watt-hour battery, whilst 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 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 triggered many new architectural developments at the platform level. Reducing display power means longer battery lifespan 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 is becoming more integrated into the entire system design. The brand new eDP v1.4 brings most of these concepts together, as explained inside the following discussion.
