Patent ID: 7750882

Claim:
A display apparatus for displaying display data, comprising: a plurality of first lines; a plurality of second lines intersected with said plurality of first lines; a display panel including a plurality of pixels arranged in a matrix, each of the pixels being connected to one of said first lines and one of said second lines; a first driver applying a gray scale voltage to said first lines in response to said display data; and a second driver applying a selection voltage to at least one of said second lines in a case of selecting a line of said pixels and applying a non-selecting voltage to at least one of said second lines in a case of not selecting a line of said pixels, wherein a second line corresponding to a line of a first pixel is located next to a second line corresponding to a line of a second pixel, wherein electric potential of a pixel electrode corresponding to said line of said second pixel is changed to high level through a capacitance when voltage is applied to said second line corresponding to said line of said first pixel, wherein said second driver line sequentially applies said selection voltage to each line of said second lines, wherein said second driver applies said selection voltage once per line to said second lines in one frame period, wherein said second driver applies said selection voltage to one line of said second lines in a first period of one horizontal scanning period and applies said non-selecting voltage to said same one line of said second lines in a second period of said same one horizontal scanning period, wherein said second driver applies said non-selecting voltage to both an (n−1)th second line and an nth second line within a period from when applying said selection voltage to the (n−1)th second line within an (n−1)th horizontal scanning period terminates to when applying said selection voltage to an nth second line within an nth horizontal scanning period begins, wherein said second driver includes a register for setting the period from when applying said selection voltage to the (n−1)th second line within an (n−1)th horizontal scanning period terminates to when applying said selection voltage to an nth second line within an nth horizontal scanning period begins, and wherein said display device controls an abnormal increase of the effective value of said electric potential of said pixel electrode by changing said first period based on parameter of said register.
