+RPI_DPI_RGB Display Driver
+===========================
+
+.. seo::
+    :description: Instructions for setting up 16 bit "RPI_DPI_RGB" parallel displays
+    :image: waveshare_touch-s3.jpg
+
+.. _rpi_dpi_rgb:
+
+Models
+------
+This display driver supports displays with 16 bit parallel interfaces, often referred to as "RPI_DPI_RGB" type.
+These have a parallel interface but no SPI interface and require no configuration of the driver chip.
+
+This driver has been tested with the following displays:
+
+  - Waveshare ESP32-S3-Touch-LCD-4.3
+  - Makerfabs 4.3" display (Sunton)
+
+Usage
+-----
+This component requires an ESP32 (usually an ESP32-S3 because of the number of GPIO pins required) and the use of
+ESP-IDF. PSRAM is a requirement due to the size of the display buffer.

+- **spi_mode** (*Optional*): Set the mode for the SPI interface to the display. Default is ``MODE0`` but some displays require ``MODE3``.

+
+The horizontal and vertical ``pulse_width``, ``front_porch`` and ``back_porch`` values are optional, but may require
+changing for a specific display. Refer to the manufacturer's sample code for suitable values. These specify timing
+requirements for the display.
+
+The ``init_sequence`` requires a list of elements, one of which may be a single integer selecting a canned init
+sequence (the default and currently the only sequence is 1), the remainder must be byte arrays providing additional
+init commands, each consisting of a command byte followed by zero or more data bytes.
+
+These will be collected and sent to the display via SPI during initialisation.
