OLED Panels for distortion-free VR?
Posted: Tue Oct 11, 2016 6:10 pm
Hi all, good to meet you!
I've been experimenting with an optical arrangement that outperforms those used in the current generation of VR/AR headsets, where there's no chromatic aberration or significant "screen door" effect. Pixels aren't barrel distorted, which means you can make the most out of the display panel. I can barely see the pixels .
As well, I've been ray tracing some designs that allow for 130 * 60 degree FOV per eye, without any of the nasty smearing you see from Fresnel lenses, etc. I have not yet been prototyping this particular optic IRL though, as I'd like to get the aforementioned simpler geometries prototyped first.
--Anyway!--
I'm looking for some OLED panels to build a demo headset with. I've purchased the Topfoison TF38101A dev kit, and it *appears* to be just an STM32, a MIPI-DSI converter IC & some other supporting hardware. However, the company has been reluctant to collaborate with "western DIY people", as it seems they have tried working with flakes in the past.

They have not overclocked the MIPI-DSI bridge, so I need to do some register tweaking to get this guy to support 90Hz. As far as I can tell, the board simply programs the Toshiba TC358870XBG during "boot" over an i2c bus, so theoretically, it should be possible to rip the instructions off and rewrite the code for the STM32, as the TC3x does not have non volatile memory from what I can tell.

Does anyone see a path to success here? Would love to hear from the forum!
