.. py:class:: IS31FL3741(*, width: int)

   Displays an in-memory framebuffer to a IS31FL3741 drive display.

   Create a IS31FL3741 object with the given attributes.

   The framebuffer is in "RGB888" format using 4 bytes per pixel.
   Bits 24-31 are ignored. The format is in RGB order.

   If a framebuffer is not passed in, one is allocated and initialized
   to all black.  In any case, the framebuffer can be retrieved
   by passing the Is31fl3741 object to memoryview().

   A Is31fl3741 is often used in conjunction with a
   `framebufferio.FramebufferDisplay`.

   .. py:attribute:: brightness
      :annotation: :float

      In the current implementation, 0.0 turns the display off entirely
      and any other value up to 1.0 turns the display on fully.


   .. py:attribute:: width
      :annotation: :int

      The width of the display, in pixels


   .. py:attribute:: height
      :annotation: :int

      The height of the display, in pixels


   .. py:method:: deinit() -> None

      Free the resources associated with this
      IS31FL3741 instance.  After deinitialization, no further operations
      may be performed.


   .. py:method:: refresh() -> None

      Transmits the color data in the buffer to the pixels so that
      they are shown.
