Abstract:
A display apparatus comprising:a correcting means for producing a current corrected data signal by using a current image data signal and a previous corrected data signal; a storage means for storing said current corrected data signal within a predetermined frame period and outputting said current corrected data signal as the previous corrected data signal in such a manner as to be delayed at most said predetermined frame period; and a display means driven by a driving signal corresponding to said current corrected data signal, wherein said correcting means includes means for producing a current image data signal as the current corrected data signal when the current image data signal is equal to the previous corrected data signal, producing a value greater than said current image data signal as the current corrected data signal when said current image data signal is greater than the previous corrected data signal, and producing a value smaller than said current image data signal as the current corrected data signal when said current image data signal is smaller than the previous corrected data signal so that producing a change in the current corrected data signal is greater than a change of the current image data signal for a first predetermined frame period, smaller than the change of current image data signal for a second predetermined frame period and converging to the change of current image data signal for a third predetermined frame period.
