Note: Motherboard Requirements for Flat Panel Display:
Flat panel display support must be implemented using the defined LVDS
interface for screen resolutions up to and including 1920x1200.
LVDS implementation must support single-channel and dual-channel interface
widths, 18-bpp and 24-bpp color depths, VESA and JEIDA color mappings, and
configurable display timings. Board must have a mechanism for choosing
between such settings and furthermore apply different EDID (or at a
minimum, 18-byte DTD) panel-specific timings to accommodate diverse panel
selection from all chassis vendors.
Motherboard must provide mechanism for adjusting inverter/driver board
settings, namely: maximum PWM, minimum PWM, frequency and polarity.
Intel will maintain a list of panel and inverter/driver board specifications as
registered by chassis vendors (to be available separately).
Motherboard must also provide 5V power to flat panel display and 19V power
to inverter/driver board, each at up to 3A current rating.
AiO Chassis Requirements for Flat Panel Display:
Flat panel displays with a screen resolution up to (and including) 1920x1200
must be LVDS-based. Chassis vendor is responsible for providing panel-
specific datasheet, panel-specific timing information (128-byte EDID data, or
at a minimum 18-byte DTD structure) and inverter/driver board datasheet to
Intel as early as possible for Intel to confirm (and if necessary, disseminate
across board vendors) the necessary display support.
Flat panel display must operate at 5V input voltage. Please also consult with
Intel shall the panel input voltage requirement be different than 5V (for
market assessment purposes only).
Inverter/driver board must operate at 19V input voltage and be matched to
the target panel backlight unit (BLU) specifications so that:


Failure to ensure matching inverter/driver board-to-panel specifications may
result in shortened display life, hardware failure and/or customer
dissatisfaction.

maximum inverter/driver board current output (when driven at 100%
PWM) does not exceed the BLU's current input tolerance,
and minimum inverter/driver board current output remains within the
BLU's specification while still producing a legible screen output.
