The Shineworld LH133K is a 1.3" 240x240px RGB LCD with a MIPI DBI
compatible SPI interface.
The initialization procedure is quite basic with the exception of
requiring inverted colors.
A basic mipi-dbi-cmd[1] script to get the display running thus looks
like this:

    $ cat shineworld,lh133k.txt
    command 0x11 # exit sleep mode
    delay 120

    # The display seems to require display color inversion, so enable it.
    command 0x21 # INVON

    # Enable normal display mode (in contrast to partial display mode).
    command 0x13 # NORON
    command 0x29 # MIPI_DCS_SET_DISPLAY_ON

    $ mipi-dbi-cmd shineworld,lh133k.bin shineworld,lh133k.txt
