Are you quite sure the chip-select of the tpo,td028ttec1 panel is active-high? A quick google produced a datasheet which seems to indicate that XCS is active-low? See page 17 here: http://www.lcd-source.com/datasheet/TPO/TD028TTEC1.pdf It is of course possible that you are driving that line behind some inverting circuitry. Hardware designers seem to do that all the time, if they need to go from one voltage domain to the other, etc.
