Hello,

I am writing to request the procurement of a 128x64 LCD display that adheres to the SPI communication protocol and complies with all the specifications outlined in the image file provided below(Cases 1, 2, 3, 4).

  Hello,

  None of our graphic LCDs support the cases with 4-pixel and 6-pixel vertical spacing.  The best workaround for this is to use a display with the ST7565 controller.  You will need to create custom characters to accommodate cases 3 and 4.

  For case 3:

  • Page 0: Top half of "A" in rows 5-8
  • Page 1: Bottom half of "A" in rows 1-4
  • Page 2: Character "B"

  For case 4:

  • Page 0: Top half of "A" in rows 5-8
  • Page 1: Bottom half of "A" in rows 1-4
  • Page 2: Top 3/4 of "B" in rows 3-8
  • Page 3: Bottom 1/4 of "B" in rows 1-2

  Is there any other 128x64 LCD (except graphic LCD) available that can fulfill the above conditions?

  Hi,

  Unfortunately, we are not aware of any displays that support this specific functionality.

  Hello,

  I believe that the NHD-2.7-12864WDW3-M display unit aligns with the stated requirements, as it is equipped with the SSD1322 Driver IC. Kindly verify this information and provide any additional details or clarifications if necessary.

  Hello,

  Yes, it should be possible to implement your requirements with the SSD1322 driver IC.  The SSD1322 IC supports row address commands instead of page address commands, so you should be able to specify 4-pixel and 6-pixel spacing.
