Why do large Multi-function Displays cost so much?

Mike,

I think an evaluation of cost per inch is the wrong measurement metric. As you increase the diagonal inch size, the increase of the screen area is not proportional.

A better evaluation metric would be cost per unit of area. To this end, I calculated the area of the screen for the Garmin 7600xsv models vs. their MSRP. The functions are largely the same; there are some minor differences as the units get larger such as additional video inputs. More power is required, so Frank has a valid point that larger (more expensive) power supplies are needed as the units increase in size.

The results were somewhat surprising. By far the most expensive unit on a price-per-inch basis is the 7" 7607xsv - the smallest model. The 8" model is the least expensive, with the 10", 12", and 16" incrementally more expensive. That increase in cost could be attributed to materials, extra ports, carrying costs, etc.

There are other metrics to consider though. Such as total pixels, pixels per inch of screen area (resolution), and cost per pixel. If you look at these, the 10" model has the highest resolution. But the 7" and 8" models have the lowest cost per pixel. Somewhat surprisingly to me, the largest model 16" model has the lowest resolution and the highest cost per pixel.

The best value of resolution vs. cost per pixel would be the 10" model.

That is an awesome evaluation. What were the prices used for this?

It is September, my boat is still in the water, yet it feels like January in this thread.

Hey, nerdy stuff knows no season. You should see my spreadsheets on Star Trek.

I like to see the Star Trek spreadsheets.....i'm a big fan myself......:confused:.....

My almost adult son is a bit of a tech/electronics geek and builds his own stuff, buying components from China and other places. He figures a multi-touch 15 inch panel at retail one-off volumes from China is probably $500 to $600 max, so in volume a lot less. 7 inch maybe $200 - 300. So the contribution margin is clearly pretty high on the larger screens for the mfgs. (Now I need to convince him to build me a glass console from a few of the cheap 5" MFDs and other components. I better do that before he graduates from Comp Science in April or I won't be able to afford him)

(He built me a "Big Mouth Billy Bass" that is now a Google internet device. "Hey google......" and the bass talks the response. If he can do that surely he can do something really useful.)

Cliff, do you listen to the Star Trek: The Next Conversation podcast?

I listen to a variety and it's a particularly good one. The hosts are kind of quirky and it's not terribly "smooth", but very authentic and engaging. Has a devoted following including a very active Facebook group that discusses, well, the podcast.

I'm kind of the self-appointed statistician that tracks various data points about the podcast and makes charts.

Examples:

STTNC Cumulative MVC-S3E19.jpg STTNC Division MVC Rank-S3E19.jpg STTNC MultiSeason MVC Rank-S3E19.jpg STTNC MVC Rank-S3E19.jpg

This is getting kind of off-topic and I don't want to hijack the thread, so I'll stop here.
