Controller board runs embedded DisplayPort

April 23, 2015 // By Julien Happich
Distec has introduced the autonomous TFT controller board PrismaECO-eDP running embedded DisplayPort (eDP) as an input interface as it enables higher data rates and improved EMI performance at optimized power consumption versus LVDS.

The eDP interface is available in all current Intel and AMD chips, especially in the notebook / ultrabook area, therefore it replaces LVDS officially on PC platforms this year.

In addition to PRISMAeco-eDP the range of Distec's intelligent eDP solutions includes the small LVDS2eDP interface. Integrated in the customer's existing design, it simply converts the existing LVDS interface to eDP. Thus the customer may keep his controller solution but still use one of the modern, sleek full-HD displays. The board supports a resolution of WSXGA (1600x900) to WUXGA (1920x1200).

The brightness of the backlight can be controlled via Pulse Width Modulation (PWM) or analog voltage, but can also be adjusted automatically to ambient light conditions by using an optional ambient light sensor. An exclusive configuration software enables port selection, timing, EDID programming and many other settings. This is particularly useful for system integrators who can adjust the PrismaECO-eDP individually for each customer.
