Appeal 2007-3283
Application 10/271,594
of electrodes and liquid crystal sandwiched therebetween, and being divided
into a plurality of pixel groups each composed of plural pixels,
the method comprising:
performing a predetermined computing operation at intervals of a
predetermined horizontal period by adding all gradation display data
representative of gradations of pixels of one of the pixel groups;
correcting a voltage determined from gradation data of each pixel of
the one pixel group, on the basis of a result of the computing operation, to
obtain a corrected voltage; and
applying the corrected voltage between a pair of electrodes of each
pixel of the one of the pixel groups during the predetermined horizontal
period in order to reduce non-uniformity of a display.
The prior art relied upon by the Examiner in rejecting the claims on
appeal is:
Tamai US 5,642,127 Jun. 24, 1997
Kimura US 5,892,494 Apr. 6, 1999
The Examiner rejected claims 1, 3, 5, and 10 under 35 U.S.C. § 103(a)
based upon the teachings of Kimura. The Examiner rejected claims 8 and 9
under 35 U.S.C. § 103(a) based upon the teachings of Kimura and Tamai.
Appellants contend that the claimed correction voltage is applied
between a pair of electrodes of each pixel of a group of pixels during a
predetermined horizontal period whereas the reference to Kimura describes
correcting an application voltage based upon the length of time a pixel has
been turned on (i.e., making the correction after the need for the correction
has occurred) (Br. 10 to 12). According to the Examiner:
