Title: NHD-1.5-128128UGC3 Maximum Frame Rate
Post by: rbairos@gmail.com on February 08, 2016, 02:13:52 PM
Hello. I'm trying to achieve 96x64 color resolution at  256 frames per second.

If I use NHD-1.5-128128UGC3  (SSD1353)

Am I correct in assuming I can use this module if I set the mux to 64 n(down from 128) and only update 96 columns (down from 128) ?

My calculation:

Fosc = 2.8Mhz
D = 1
K = 147
M = 64
Frm = 297.6  Frames per second


Similarly, I can update the screen in time:
1,000,000,000 nanoseconds / 300 nanoseconds per write / 2 bytes per pixel = 1.666 megapixels per second 
/ 256 refreshes = 6510 pixels per refresh

6510 pixels = 96 * 67.8   (or about 5% breathing room).

Are there any issues with refreshing the pixels that fast?

Thank you very much!
Rob.

Maybe a simpler question:

Does anyone have this module, willing to set the mux to 64 (instead of 128), and seeing if it generates a stable (though half) display?

Something like:

oled_Command_128128RGB(0xA8); //set multiplex ratio
oled_Data_128128RGB(63);  // mux = 64

10.1.12Set Multiplex Ratio (A8h)
This command switches default 1:132 multiplex mode to any multiplex mode from 16 to 132. For example,
when multiplex ratio is set to 16, only 16 common pins are enabled...
