Method of operation for an active matrix type display device

Claim 1

A method of operation for an active matrix type display device including: an m number (m≧2) of pixel array blocks arranged in a row direction, each pixel array block having a plurality of display elements (Cij; i=1,2, . . . k; j=1 . . . n) arranged as a K rows×n columns (K≧2, n≧1) array; a K+1 number of scanning lines (G1, . . . , GK+1) arranged in said row direction in each pixel array block to supply scanning signals for selectively scanning the corresponding display elements; a j+1 number of data lines (D1 . . . Dj+1) arranged in a column direction in each pixel array block to supply data signals to the corresponding display elements and located in an intersecting fashion to said scanning lines; and first and second switching elements (TKnA, TKnB) connected between the data lines and the corresponding display element and independently connected to two adjacent scanning lines, respectively, between which the respective display element for the first and second switching elements is located, whereby different display data input routes are established relative to the display elements via two adjacent data lines in a j+1 number of data lines, said method comprising the step of enabling the display elements on a respective row which are included into said plurality of display elements in the matrix array constituted by the pixel array block to display back-up and normal display data for respective odd-and-even-numbered frames, and including the steps of: (a) sequentially writing normal red, green and blue display data into the corresponding display elements on one row, while at the same time sequentially writing back-up red, green and blue display data into diagonally adjacent corresponding display elements, in accordance with scanning signals selected by a common scanning line, relative to display elements, located between one row and another adjacent row; and (b) writing the normal red, green and blue display data into said diagonally adjacent display elements, in place of said back-up red, green and blue display data, in accordance with scanning signals selected by another scanning line adjacent to said scanning line.

Claim 2

A method of operation for an active matrix type display device including: an m number (m≧2) of pixel array blocks arranged in a row direction, each pixel array block having a plurality of display elements (Cij; i=1,2, . . . k; j=1 . . . n) arranged as a K rows×n columns (K≧2, n≧1) array; a K+1 number of scanning lines (G1, . . . , GK+1) arranged in said row direction in each pixel array block to supply scanning signals for selectively scanning the corresponding display elements; a j+1 number of data lines (D1 . . . Dj+1) arranged in a column direction in each pixel array block to supply data signals to the corresponding display elements and located in an intersecting fashion to said scanning lines; and first and second switching elements (TKnA, TKnB) connected between the data lines and the corresponding display element and independently connected to two adjacent scanning lines, respectively, between which the respective display element for the first and second switching elements is located, whereby different display data input routes are established relative to the display elements via two adjacent data lines in a j+1 number of data lines, said method comprising the step of enabling the display elements on a respective row which are included into said plurality of display elements in the matrix array constituted by the pixel array block to display back-up and normal display data for respective odd-and-even-numbered frames, and including the steps of: (a) sequentially writing normal red, green and blue display data into the corresponding display elements on one row, while at the same time sequentially writing back-up red, green and blue display data into diagonally adjacent corresponding display elements, in accordance with scanning signals selected by a common scanning line, relative to display elements, located between one row and another adjacent row; and (b) writing the normal red, green and blue display data into said diagonally adjacent display elements, in place of said back-up red, green and blue display data, in accordance with scanning signals selected by another scanning line adjacent to said scanning line.
