Image display method and liquid crystal display device employing same

摘要

Uniformize afterimages caused by black insertion to each image when two types of images are alternately displayed. There are provided a left and right image alternate output unit, a mask pattern storage unit, a mask pattern selection counter, and a mask synthesizing unit. The left and right image alternate output unit alternately outputs two types of video frames. The mask pattern storage unit stores m mask patterns, wherein basic regions are defined in a pixel region of a liquid crystal panel, the pixel region has m pixels arrayed in a matrix, m is an even number equal to or greater than 4, the in mask patterns have different arrangements of mask pixels in the basic region, and the number of the mask pixels is an even number smaller than m and equal to or greater than 2.

1. An image display method, wherein black insertion is provided to two types of video frames, the method comprising:
defining basic regions in a pixel region of a liquid crystal panel, the basic region being a pixel region having m pixels arrayed in a matrix, wherein m is an even number equal to or greater than 4, setting the number of pixels subjected to black insertion in the basic region at an even number less than m and equal to or greater than 2, when m-frame cycles are composed of the two types of the video frames which are alternately displayed on the liquid crystal panel, sequentially providing m black display patterns to each of the basic regions for each frame, the m black display patterns having different arrangements of the pixels subjected to black insertion in the basic region; and repeating the sequentially providing of the m black display patterns in m-frame cycles, wherein each of the pixels in the basic region is subjected to black insertion by the same number of times throughout the m black display patterns.
