I added support for this display to my bb_spi_lcd library. What functions does ESPHome need from the display library? Just pushing pixels? text? boxes?

ESPHome currently only supports qspi-amoled. qspi-lcd is not yet supported.

QSPI amoled and QSPI LCD are identical interfaces. The only difference will be the initialization sequence. I support both types in my bb_spi_lcd library.

Yes, currently ESPHome can initialize two display models, RM67162 or RM690B0。 I don't know how to reference your display library in ESPHome. Hope you can provide tips and assistance

QSPI amoled and QSPI LCD are identical interfaces. The only difference will be the initialization sequence. I support both types in my bb_spi_lcd library.

display:
  - platform: qspi_amoled
    model: RM690B0
    data_rate: 80MHz
    spi_mode: mode0
    dimensions:
      width: 360
      height: 360
      offset_width: 16
    color_order: rgb
    invert_colors: false
    brightness: 255
    cs_pin: 10
    reset_pin: 47
    update_interval: never
    auto_clear_enabled: false
    id: my_display

I referenced the wrong display model, resulting in a complete display error

I don't use ESPHome and don't have spare time to work on it. I mentioned my code because it's an Arduino library that supports a ton of LCD displays in a much simpler way compared to libraries like TFT_eSPI. If there is funding available for this effort, I can provide more assistance.

I'm making a simpler version of my library for LVGL and ESP-IDF. Perhaps that will be easier to adapt to ESPHome? Here's my AnimatedGIF library + my bb_spi_lcd driving the JC3636W518:

ESPHome will be even better thanks to your contribution. Thank you

It does look like the current driver supports quad SPI

Now we just need ST77916 support

Yes, looking forward to support

Should be easy enough to support now with the qspi_dbi driver and a custom init sequence. Not released yet, but available in the dev branch. Docs here:
