+
+Overview
+********
+
+This is a generic shield for display shields based on ST7789V display
+controller. More information about the controller can be found in
+`ST7789V Datasheet`_.

+Requirements
+************
+
+This shield can only be used with a board that provides a configuration
+for Arduino connectors and defines node aliases for SPI and GPIO interfaces
+(see :ref:`shields` for more details).
+
+Programming
+***********
+
+Set ``-DSHIELD=st7789v_tl019fqv01`` when you invoke ``west build``. For example:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/gui/lvgl
+   :board: nrf52840_pca10056
+   :shield: st7789v_tl019fqv01
+   :goals: build
