+RK043FN02H-CT Parallel Display
+##############################
+
+Overview
+********
+
+RK043FN02H-CT is a 4.3 inch TFT 480*272 pixels with LED backlight and
+capacitive touch panel from Rocktech. This LCD panel can work with several i.MX
+RT EVKs and LPC MCUs for evaluation of applications with display.
+
+More information about the shield can be found at the `RK043FN02H-CT product
+page`_.
+
+This display uses a 40 pin parallel FPC interface plus 6 pin I2C interface,
+available on many NXP EVKs. Note that this parallel FPC interface is not
+compatible with the MIPI FPC interface present on other NXP EVKs.
