Display apparatus and driving method thereof

A method for driving a display panel comprising:

• receiving one or more frames of image data one after another each of which having image data for a plurality of subpixels in the display panel;
• determining an initial driving voltage corresponding to one subpixel of the plurality of subpixels based on each frame of image data;
• determining an overdrive voltage corresponding to the one subpixel based on the initial driving voltage and a compensation voltage corresponding to the one subpixel, wherein an amplitude of the overdrive voltage is greater than an amplitude of the initial driving voltage;
• applying the overdrive voltage to the one subpixel for an overdrive time period followed by applying the initial driving voltage to a same one subpixel for displaying a subpixel image associated with each frame of image data;
• and
• determining the overdrive time period during which the overdrive voltage is applied to the one subpixel;
• wherein applying the overdrive voltage to the one subpixel comprises sending the overdrive voltage via a signal line to the one subpixel using a data driver;
• applying the initial driving voltage to the same one subpixel comprises sending the initial driving voltage via a same signal line to the same one subpixel using a same data driver;
• wherein the overdrive time period is determined to be positively correlated to a length of the signal line.

A display apparatus, comprising:

• a display panel having a plurality of subpixels;
• an image receiver configured to receive one or more frames of image data one after another, each of which having image data for the plurality of subpixels;
• an overdrive voltage generator coupled to the image receiver and configured to determine an initial driving voltage for a subpixel based on each frame of image data and to determine an overdrive voltage based on the initial driving voltage and a compensation voltage corresponding to a same subpixel, wherein an amplitude of the overdrive voltage is greater than an amplitude of the initial driving voltage;
• and
• a subpixel driver configured to apply the overdrive voltage to the subpixel for an overdrive time period and to apply the initial driving voltage to the same subpixel subsequent to the overdrive time period;
• wherein the subpixel driver comprises a gate driver and a data driver, the gate driver being configured to scan through each row of the plurality of subpixels, the data driver being configured to send the overdrive voltage corresponding to the subpixel followed by the initial driving voltage corresponding to the same subpixel via a signal line to the subpixel, the overdrive time period being positively correlated to a length of the signal line connected between the data driver and said subpixel.
