weixj2003ld,
Be aware that histogram equalization changes the pixel values. It is better
used for display purposes only.
You should choose between Byte and UInt16 or any other type based on the
range of pixel values in the raster band.

weixj2003ld,
I couldn't open the link.
Try gdalinfo -mm des.png on both the output images. I think they will both
give the same output. UInt16 should give a dark image unless you perform
histogram equalization on it.
