Anyone else want to post theirs?

If the screen is actually made by Samsung then some of the more rabid HTC fanboys won't be able to bring themselves to touch it .

Ugh...mine is Samsung too! You are not wrong about the HTC fanboys. In fact many Taiwanese will not be happy to hear it has a major Korean part! There is a lot of rivalry there!

JDI is Japanese Display Inc (Sony/Toshiba/Hitachi).. not sure how Samsung is there too. A sexpert on HTC panels needs to step in.

I just googled JDI. Indeed you are absolutely right. But JDI has no link to Samsung. In fact they are absolute rivals. Looks like the phone has an identity crisis!

The file is huge. The best thing is to copy it off the phone so you can search for it easily on your PC.

I think the screen itself is JDI made and the 'Samsung' is.. something else.

For example, in the SHARP_RENESAS option, Sharp is the only one of the two who manufactures screens and Renesas is a semiconductor manufacturer who doesn't.

Again, we need an HTC expert to clear things out because it isn't displayed this way for other OEMS.

Ah..you provided a clue. Renesas make the ICs for screen drivers/controllers. So this implies the JDI screen is powered by a Samsung screen driver/controller. Still a bit surprising to see anything with Samsung there but not quite as shocking as the screen itself!

4. Find "last_kmsg"
5. Open it on the device or send it to a PC and open it as a text file. Your looking for "panel_id" and "panel_vendor." It's a long ass file so you're better off using an editor with a search feature to search on "panel."

Renesas SP is a joint venture established by Renesas Electronics, Sharp Corporation and Powerchip Group in April 2008. It engages in the business of LCD Drivers that drive small and mid-sized LCD panels. As a top manufacturer in the display products market for mobile gadgets, it aims at making a significant contribution to the global display industry through continuous innovation, cost reduction and quick operations. It provides excellent sales support, quality designing and manufacturing skills and quality assurance system all over the world aiming to become a genuinely reliable company.


All these 1080P mobile displays are being made in a former Sharp plant the size of a football field that was dedicated to larger panels for use in TVs and was converted to small format displays and is now the largest physical plant dedicated to mobile devices in the world.
