Abstract
Abstract A display device, which takes a specified period to rewrite the picture elements in one horizontal scanning period, comprises M pcs. of scanning lines divided into a plurality of groups each containing K pcs. of scanning lines (K > 1, M > 1, K, M: positive integers) and elements for supplying scanning signals to the M pcs. of scanning lines to rewrite an image. The scanning signal-supplying elements output scanning signal to the first scanning line of each group in the first frame, to the second scanning line of each group in the second frame, and to the Kth scanning line of each group in the Kth frame so that the M pcs. of scanning lines are rewritten by K times of scanning.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
A display device which takes a specified period to rewrite the picture elements in one horizontal scanning period, comprising: M pcs. of scanning lines divided into a plurality of groups each containing K pcs. of scanning lines (K > 1, M > 1, K, M: positive integers); and means for supplying scanning signals to the M pcs. of scanning lines to rewrite an image; wherein the means for supplying scanning signals outputs scanning signal to the first scanning line of each group in the first frame, to the second scanning line of each group in the second frame, and to the Kth scanning line of each group in the Kth frame so that the M pcs. of scanning lines are rewritten by K times of scanning.
Claim 2
Dependent Claim
126 words
A display device which takes a specified period to rewrite the picture elements in one horizontal scanning period, comprising: M pcs. of scanning lines divided into a plurality of groups each containing K pcs. of scanning lines (K > 1, M > 1, K, M: positive integers); and means for supplying scanning signals to the M pcs. of scanning lines to rewrite an image; wherein the means for supplying scanning signals outputs scanning signal to the first scanning line of each group in the first frame, to the second scanning line of each group in the second frame, and to the Kth scanning line of each group in the Kth frame so that the M pcs. of scanning lines are rewritten by K times of scanning.
Claim 3
Dependent Claim
28 words
The display device of claim 1, wherein assuming the specified period required for rewriting picture element is r, the display device satisfies the condition of 60 > .
Claim 4
Dependent Claim
16 words
The display device of claim 1, wherein the display device is a liquid crystal display device.
Claim 5
Dependent Claim
94 words
A display device having a matrix array of display elements, scanning and data electrodes, and a display control circuit for applying scanning signals to said scanning electrodes and data signals to said data electrodes, said display control circuit being arranged to perform a succession of scanning operations in each of which a plurality (P) of said scanning electrodes are sequentially energised, wherein a complete scanning of the matrix array involves a plurality (K) of said scanning operations in each of which corresponding scanning electrodes from a plurality (P) of groups thereof are sequentially energised.
Claim 6
Dependent Claim
94 words
A display device having a matrix array of display elements, scanning and data electrodes, and a display control circuit for applying scanning signals to said scanning electrodes and data signals to said data electrodes, said display control circuit being arranged to perform a succession of scanning operations in each of which a plurality (P) of said scanning electrodes are sequentially energised, wherein a complete scanning of the matrix array involves a plurality (K) of said scanning operations in each of which corresponding scanning electrodes from a plurality (P) of groups thereof are sequentially energised.
Claim 7
Dependent Claim
67 words
A display device according to claim 4 wherein the matrix is divided into a plurality of sections, each including a respective set of said scanning electrodes, each set comprising a said plurality of scanning electrode groups, the display control circuit being operable so that in each said scanning operation the sequential energization of the corresponding scanning electrodes from the groups of said respective sets takes place simultaneously.
