The product schematic for NHD-7.0-HDMI-N-RTXL-CTU does not show the dimensions of the edge of LCD so it is difficult to know where to put a gasket between the LCD and a bezel.  And the edge widths are different for both top and bottom, and right and left.

The mounting guide says the gasket should be 0.5 mm from Edge of Touch Screen Top Layer.  The LCD has metal edges, so is the 0.5 mm from the edge ?
And how wide can the gasket be?

  It is recommended that the gasket be placed at least 0.5mm from the outside front surface edge of the CTP. Then up tp 1.0mm from the inside edge of the metal bezel frame of the TFT beneath the CTP glass to provide a stable compressible surface.  The gasket compression should not press the gasket over the outside edge and also should not compress the CTP glass over the air gap on the inside area of the TFT display. This will help prevent interference with the touchscreen due to distortion of the glass.
  
  The NHD-7.0-HDMI-N-RTXL-CTU display module contains the TFT display NHD-7.0-800480EF-ATXL#-CTP.
  The datasheet for this TFT display will include the dimensions of the metal bezel frame edge widths.
