    The embedded DisplayPort (eDP) standard consumes less power than the on-the-way-out LVDS method, and a new update from VESA should cut down on energy usage even more. The reduced power-sipping comes thanks to a new partial-frame update feature for Panel Self Refresh, regional backlight controls, additional link rate options and other tweaks. The upcoming release of eDP Version 1.4 will also support a wider range of mobile devices, including tablets, laptops and "handhelds," and the auxiliary channel can now carry a display's multitouch data to the system processor. Additionally, VESA says this latest version of eDP will allow for increased battery life and allow for thinner, lighter devices. Look for the standard to be released in October, and it should make its way to gadgets by 2014.

  • Samsung Exynos 5 Dual white paper confirms new high marks for mobile graphics, memory performance

    Our SIGGRAPH demo of the ARM Mali-T604 GPU gave a brief preview of Samsung's upcoming Exynos 5 Dual CPU, but now all the details of the company's next great processor are ready for us to view. Other than that GPU which includes support for up to WQXGA (2,560 x 1,600) resolutions -- perfect for the 11.8-inch P10 mentioned in court filings -- and much more, the white paper uncovered by Android Authority also mentions support for features like Wi-Fi Display, high bandwidth LPDDR3 RAM running at up to 800MHz with a bandwidth of 12.8GBps, USB 3.0 and SATA III. It also claims the horsepower to decode 1080p video at 60fps in pretty much any codec, stereoscopic 3D plus handle graphics APIs like OpenGL ES 3.0 and OpenCL 1.1. All of this is comes courtesy of a dual-core 1.7GHz ARM Cortex-A15 CPU built on the company's 32nm High-K Metal Gate process and Panel Self Refresh technology that avoids changing pixels unnecessarily to reduce power consumption. There's plenty of other buzzwords and benchmarks floating around in the PDF, you can check them out in the PDF linked below or just sit back and see what tablets and phones arrive with one of these -- or the competition from Qualcomm's S4 and NVIDIA's Tegra -- inside starting later this year.

  • IDT's power-saving Panel Self Refresh tech coming to laptops, Ultrabooks and tablets (video)

    We aren't talking Pixel Qi-style savings or anything, but then again, IDT's not asking you to ditch the conventional LCD your retinas refuse to step away from. The company's Panel Self Refresh technology just got a major shot in the arm here at IDF, with the introduction of the world's first Embedded DisplayPort (eDP) 1.3-compliant Timing Controller with integrated PSR technology. A lot of technobabble, sure, but here's the lowdown: with this stuff in the mix, most users will see upwards of 45 minutes of battery gain, as the panels don't require constant refreshing. Granted, power savings are only seen with static images on-screen, and you'll need a PSR-enabled graphics processor to take advantage. The good news, however, is that Intel seems to be into the idea of using this stuff to boost the overall battery life of Chipzilla-based machines, so it shouldn't be too long before it starts popping up in laptops and Ultrabooks. As to how the magic actually works? IDT's PSR technology "identifies a static image and stores it local to the TCON in an integrated frame buffer; then, it seamlessly displays the image from the local frame buffer allowing the eDP main link and a majority of the GPU functions to be powered-down, resulting in significant power savings." Have a look at the unveiling video just after the break. %Gallery-133738%
