Abstract
A method of driving a display panel includes determining a present polarity of a pixel data signal of a present frame, generating a first compensated grayscale of the pixel data signal of the present frame using a pixel data signal of a previous frame, the pixel data signal of the present frame, and the present polarity, and displaying an image using the first compensated grayscale. The first compensated grayscale varies according to the present polarity.
Claims13
A method of driving a display panel, the method comprising:
- determining a present polarity of a pixel data signal of a present frame;
- generating a first compensated grayscale of the pixel data signal of the present frame using a pixel data signal of a previous frame, the pixel data signal of the present frame, and the present polarity, wherein the first compensated grayscale varies according to the present polarity;
- displaying an image using the first compensated grayscale;
- merging the present polarity with the pixel data signal of the present frame generate a merged signal of the present frame;
- and
- extracting the present polarity from the merged signal of the present frame.
A display apparatus comprising:
- a pixel polarity determining circuit configured to determine a present polarity of a pixel data signal of a present frame;
- a grayscale compensating circuit configured to generate a first compensated grayscale of the pixel data signal of the present frame by using a pixel data signal of a previous frame, the pixel data signal of the present frame, and the present polarity, wherein the first compensated grayscale varies according to the present polarity;
- and
- a display panel configured to display an image using the first compensated grayscale, wherein
- the pixel polarity determining circuit is configured to output the present polarity to a data buffer,
- the data buffer is configured to merge the present polarity with the pixel data signal of the present frame to generate a merged signal of the present frame;
- and
- the grayscale compensating circuit is configured to extract the present polarity from the merged signal of the present frame.
A method of driving a display panel, the method comprising:
- determining a present polarity of a pixel data signal of a present frame;
- merging the present polarity with the pixel data signal of the present frame to generate a first merged signal of the present frame;
- delaying the first merged signal to generate a second merged signal of a previous frame;
- extracting the present polarity from the first merged signal;
- extracting a previous polarity of a pixel data signal of the previous frame from the second merged signal;
- and
- generating a first compensated grayscale using the pixel data signal of the previous frame, the pixel data signal of the present frame, the previous polarity, and the present polarity,
- wherein the first compensated grayscale varies according to the previous polarity and the present polarity.
