==============
I’ve read all of your comments, and together they pretty much tell the entire story. At Lenovo we love IPS display technology. I still fondly remember the ThinkPad A30p, which I believe was our first ThinkPad to have an IPS panel. It was beautiful, and as a photographer, I could appreciate the wider viewing angle and vibrant, accurate colors. To this day I won’t do any photo editing on my laptop because, frankly, every laptop display panel choice is equally pitiful for this task.

We can blame the explosion in high definition TVs as a primary reason for the demise of the IPS panel for notebook displays. High resolution IPS panels are expensive, low-yield SKUs for LCD glass manufacturers. Not many wanted to make them in notebook sizes of 14 or 15 inches when they could make more money selling 40 or 50 inches at a time to TV vendors. We stopped offering this technology because we could not procure a reliable supply.

That last statement sounds so disingenuous coming from Lenovo, doesn’t it? The non-China side of the business has never been good at supply. We make great products, but getting them to market has been our biggest problem. The X60 Tablet supply thread has been this blog’s most popular thread — and not for good reason.

As much as the conspiracy theorists would like to prove otherwise, we don’t want to introduce a product we can’t deliver. When we qualify components, we try to multiple source everything so that when one supplier is having their own supply/quality issues, we can switch over without impacting our delivery schedules. Display technology is tricky as there are many fewer quality vendors supplying panels than for just about any other piece part in a notebook.

There was only one supplier of IPS panels that was able to produce to our quality specifications. However, that supplier was unable to consistently deliver. We were not meeting the demand and were falling farther and farther behind. Thus we had to drop it. Incidentally, this same situation explains a lot of the X60 Tablet SXGA+ supply problem as well. 12 inch SXGA+ panels are pretty hard to come by.

I know a lot of you want to know about whether high resolution displays will be available on the next generation of products. Unfortunately I can’t comment on unannounced product, but I can say that we are committed to offering high-resolution, high-quality choices for our customers. We’re also looking at LED backlighting technology as well, but that has its own issues to solve. I’ll save a post on that for another time.

As a final note, we’re also working VERY hard to improve supply in general. I could tell you that we’re consolidating 43 separate systems into one SAP system, moving away from machine type-models into true configure to order, and in parallel running a thousand other supply-related projects. But as a customer you don’t care about our problems. You just want your order to show up when promised. I don’t blame you. I feel the same way.

That's a pity, I hope they can manage and the manufacturer of those IPS screens can work harder.

Being an owner of a notebook with an IPS screen, All I can say is that, I can never go back.
