Thanks for the detailed writeup, exorio. For those interested in a closer look at the hardware, it is worth mentioning that Steward has some good teardown pics on his site at https://steward-fu.github.io/website/handheld/ldk/teardown.htm
Using steward's pictures, I was able to find the lcd panel for this device on panelook: http://www.panelook.com/990001260_Innolux_2.7_LCM_overview_30682.html
. They have a datasheet available, which I
have attached to this post
was going to attach but the system doesn't like it. PM me if you want it and can't get it from Panelook.
It doesn't seem too promising in terms of potential screen upgrades though. YUV interface, 51 pins dual row, nonstandard subpixels, and "discontinued"... I don't know what's going to be out there for compatible panels. I was hoping for something more plain like 40-pin single row TTL RGB666 or RGB565... I've been out of the LCD swap game for a few years now though and I don't read mandarin, so perhaps I'm just out of touch.
Does anyone else have any suggestions or ideas for potential screen swaps for the LDK vertical? I am particularly interested to hear from:
1. The software side - Is it possible to send RGB 565 or something more conventional over the lcd output interface? Is it possible to output at a different output resolution (like true 320 x 240 RGBstripe?)
2. The shenzhen/hardware manufacturer side - Do you have any suggestions for compatible IPS or VA-style panels?
