Appeal No. 97-2020
Application 07/957,107
due to a parasitic capacitance of the thin film tran- sistors
and the like. Appellants further disclose that since these
parameters, causing the voltage variation or fluctuation, are
different in accordance with an active element of each picture
element, the fluctuation of the voltage of the picture
element can be actually suppressed in the range of plus and
minus 0.2 volts at a maximum over the whole panel.
On page 7 of the specification, Appellants state
that this invention has been implemented to solve the problems
described above in a conventional gradation displaying system.
Appellants disclose a new type of gradation displaying system
which adopts advantages of both a gradation displaying system
which is completely dependent on a voltage as shown in
Figure 1(A) and a gradation displaying system which is
completely dependent on pulse width as shown in Figure 1(B).
Appellants further disclose that their system does not require
minute voltage control and short speed pulses as pointed out
above.
