2009 Nav screen technology?
Hi All,
While the MINI's navigation screen is bright and clear in dim lighting conditions and the ambient lighting sensors work well at adjusting the brightness based on the lighting condition in the car, the screen appears even more vibrant and legible when in direct sunlight. Anyone know what screen technology is being used for the Navigation display?
I know the MINI's display isn't just upping the brightness when in direct sunlight, so what technology is it using? Transflective LCD, something else? The screen is too big and there would probably be even more of a price premium if it were OLED.
BTW, our 2007 Mitsubishi Outlander has a nice touchscreen Nav system, and while I've often jonesed for touch capabilities for manipulating the nav system, the display used in the Mitsu is totally useless in direct sunlight. Given that, I'll happily take the tradeoff to have our funky joystick control but be able to clearly read the screen during the day.
Thoughts?
Thanks!

Okay, I knew that I'd seen it somewhere, but it took me forever to figure out where I'd bookmarked it.

Brightness control of the CID
The CID is a display with a so-called ”transflective” surface. Transflective is a word combination of ”transmissive” and ”reflective”. The surface reflects the daylight that strikes it and makes other displays unreadable. This reflection means that the daylight is included in the light volume of the display. The display gains brilliance. Under poor lighting conditions or in darkness, readability is ensured by the transmissive back lighting.
The display is also heated. This improves readability and ensures that the optimized operating temperature is reached quickly even at low ambient temperatures. For brightness control of the display, a photo-transistor is integrated in the CID. For brightness control, the CID also evaluates the following signals:
Condition: the photo-transistor works with a modulation between 1 % and 50 %. If the modulation of the photo-transistor is greater than approx. 50 %, only the photo-transistor regulates the display brightness.
For brightness setting, the optional extra ”Brightness” must be selected in the ”Setup” menu in the CID.

- Dimmer signal from the footwell module (dimmer setting) via the K-CAN
- Signal via the K-CAN from the central photocell in the instrument cluster

very cool -thanks for digging this up! I had a feeling it was Transmissive as the only other tech it could have been (that I was aware of) is OLED which is still too expensive for mass production of a screen that size in a car
