Abstract

To prevent the display image from becoming unclear due to an overlap of the afterimage of the display image of the preceding frame period with the display image of the current frame period so that the image quality of the motion picture may be improved, a display apparatus includes a display surface having a plurality of pixel lines and a write circuit adapted to sequentially write an image into each of said plurality of pixel lines. The write circuit writes, during a time period for writing said image into at least one pixel line, a black color into another pixel line. The another pixel line is separated from the at least one pixel line by a predetermined distance. The write circuit writes the black color into a plurality of pixel lines separated from the at least one gate line by the predetermined distance.

Dependent claims

A display apparatus comprising:

a display surface having a plurality of pixels;
and
a write circuit adapted to sequentially write and image into each of said plurality of pixels,
wherein said write circuit writes, during a time period for writing said image into at least one pixel, a black color into another pixel sharing a common data line with the at least one pixel, wherein a gate pulse for writing the image and a gate pulse for writing the black color have the same polarity.

A display apparatus comprising:

a display surface having a plurality of data lines arranged in one direction and Y gate lines arranged in the other direction crossing said one direction, wherein said Y is an integer equal to or larger than 1, one pixel is formed at each of cross points of said data lines and said gate lines, and a plurality of pixels along each of said Y gate lines form one pixel line;
a data line drive circuit adapted to supply a data signal, which includes a black color signal portion and an image signal portion, to each of said plurality of data lines;
and
a gate line drive circuit adapted to sequentially supply a gate pulse to each of said Y gate lines;
wherein said gate line drive circuit supplies, during a write period for writing said data signal, a wide gate pulse, which gates both the black color signal portion and image signal portion of said data signal, to at least one gate line, and a narrow gate pulse, which gates said black color signal portion of said data signal, to another gate line separated from said at least one gate line;
said gate line drive circuit sequentially supplies said wide gate pulse to each of said Y gate lines during a frame period including a time periods T1 through TN, wherein the N is 1 through Y;
one frame period and next frame period are separated by a blanking period;
and said black color signal portion is written, during said blanking period, into at least one pixel line which succeeds to the pixel line into which said black color is written during the last time period TN in said one frame.
