Not good.
I could be wrong but both chips with contiguous numbers smell like custom jobs labeled with in-house part numbers. This is more likely if what you are fixing is a mass-produced appliance.
If the display is a custom design ( for example the display for a microwave oven), one of the chips might be a custom display driver and the other an OTP micro.
If the display is off-the-shelf, try getting its datasheet for more clues.
Good luck.
