              URYNOWICZ, Administrative Patent Judge.

                      This appeal is from the final rejection of claims 15 and 19-25.  Claim 1 stands                        
              allowed.                                                                                                       
                      The invention pertains to digital pulse-width modulated display systems.  Claim 15                     
              is illustrative and reads as follows:                                                                          











                                                             1
