According to the expectations of trade group Video Electronics Standards Association (VESA), the next year will be the last year that Intel and AMD will be releasing more processors with support for LVDS (Low-Voltage Differential Signaling).  This standard, allows to output video signal from the processor, chipset and graphics card to a compatible panel, in particular - the internal wiring on the LCD panel of notebook computers.  LVDS standard began to be introduced 12 years ago and, for obvious reasons, is out of date.  High intake, lack of support for new features, active interference with the wireless communication module - it is only a partial list of what caused the developers to find LVDS replacement . Specialists Faced problem ere solved in 2009 as a new connectivity standard with LCD panels - Embedded DisplayPort (eDP).  In summer 2010, a number of additions to eDP, which resulted in the release of current version now - Embedded DisplayPort 1.2.  The main improvement was the increase of eDP 1.2 transfer rates up to 5.4 Gb / s per lane, which allowed support for 120Hz online 3D (FullHD x 60 Hz x 2), as well as reduce the number of lines, making it easier, thus the internal wiring. VESA today announced the preparation of a new version DisplayPort - 1.4.  EDP 1.4 specification will be published in October this year, not later than 2014 will appear in the finished products: laptops, tablets and smartphones.  Now eDP must be part of SoC for smartphones and tablets - is one of the conditions of the new version.  Thus, one of the improvements to the standard connection panel was to expand the list of supported devices and form factors  .  Of course, now we are talking about tablets and smartphones in eDP 1.4 includes support for touch panels. On mobile devices, a lot of attention has been paid to improving the efficiency and effectiveness of the standard.  Laptops, smartphones and tablets Batteries with support for eDP 1.4 promises to work a little longer.  To do this, changes were made to the signal interface, including the reduction of voltage, the introduction of signal compression for transmission, control bit, and the proposed zone dimming backlight and screen updates. In processors Intel Haswell,  support for LVDS is not expected.   Related Products :
