Image display apparatus
View Patent ↗An image display apparatus has a hold-type display panel composed of a matrix of pixels each holding an electric signal for a predetermined period. In the image display apparatus, an intermediate value detector provides an intermediate value signal from adjacent two frames of a video signal having a first frame frequency (60 Hz), a multiplier multiplies the intermediate value signal by a coefficient that is smaller than 1, and an interpolator inserts the coefficient-multiplied intermediate value signal into the adjacent two frames of the video signal to provide a video signal having a second frame frequency (120 Hz). According to the video signal of the second frame frequency, an image is displayed on the hold-type display panel.
1. An image display apparatus having an active-matrix display panel composed of a matrix of pixels each holding an electric signal for a predetermined period to display an image, comprising:
a frame-rate converter configured to convert a first video signal having a first frame frequency into a second video signal having a second frame frequency that is higher than the first frame frequency; and
a driver configured to display an image on the active-matrix display panel according to the second video signal,
the frame-rate converter including:
an interpolation frame generator configured to generate an interpolation frame signal from frames of the first video signal;
a multiplier configured to multiply the interpolation frame signal by a coefficient that is larger than 0 and smaller than 1; and
an interpolator configured to interpolate the coefficient-multiplied interpolation frame signal into the first video signal and provide the second video signal.
