Abstract

A method of display by sub-frame driving on a monitor. The monitor has pixels arranged in an m*n array, where m and n are integers. The monitor receives a frame signal for displaying a frame for a frame periods. The frame signal includes pixel data for each of the pixels of the monitor. The frame period is divided into k sub-frame periods, a sub-frame being displayed during each of the sub-frame period. Each of the sub-frames corresponds to a driving shift voltage, and the method displays the sub-frames sequentially, wherein the method of displaying the pixel (i,j) of the p-th sub frame includes applying a driving voltage (i,j) to the pixel (i,j). The driving voltage (i,j) is a target driving voltage corresponding to the pixel (i,j) plus the corresponding driving shift voltage.

A method for driving a display having including pixels (i,j) arranged in an m*n array, i, j, m and n being integers, the display receiving a frame signal for displaying a frame for a frame period, the frame signal including pixel data for each of the pixels of the display, the method comprising the steps of:

(a) dividing the frame into a sequence of k sub-frames and the frame period into a sequence of k sub-frame periods;

(b) displaying the pixel data continuously during the sequence of sub-frames, step (b) comprising displaying each pixel (i,j) of a p-th sub-frame by applying a driving voltage (i,j) to the pixel (i,j), the driving voltage (i,j) being a target driving voltage corresponding to the pixel data for the pixel (i,j) plus a driving shift voltage corresponding to the p-th sub-frame,

wherein 1≦p≦k, 0<i≦m, 0<j≦n, p, and k are integers.

2. The method according to claim 1 , wherein the driving voltages for the pixel (i,j) at each of the k sub-frames are of the same polarity.

3. The method according to claim 1 , wherein k is set to 2.

4. The method according to claim 1 , wherein the sub-frame periods are unequal.

5. The method according to claim 1 , wherein the display is an LCD (Liquid Crystal Display).

6. The method according to claim 1 , wherein the display is an OLED (Organic Light Emitter Diode) display.

7. The method according to claim 1 , wherein the display is a PDP (Plasma Display Panel).

8. A method for driving a display having pixels (i,j) arranged in an m*n array, i,j, m and n being integers, the display receiving a frame signal for displaying a frame for a frame period, the frame signal including pixel data for each of the pixels of the display, comprising the steps of:

(a) dividing the frame period into a first sub-frame period and a second sub-frame period, a first sub-frame being displayed during the first sub-frame period, and a second sub-frame being displayed during the second sub-frame period;

(b) displaying the first sub-frame, the first sub-frame corresponding to a first driving shift voltage, step (b) comprising displaying each pixel (i,j) of the first sub-frame by applying a first driving voltage (i,j) to each pixel (i,j), the first driving voltage (i,j) being a target driving voltage corresponding to the pixel data for the pixel (i,j) plus a first driving shift voltage assigned to the first sub-frame, wherein 0<i≦m, 0<j≦n, and p is an integer; and

(c) displaying the second sub-frame, the second sub-frame corresponding to a second driving shift voltage, step (c) comprising displaying each pixel (i,j) of the second sub-frame by applying a second driving voltage (i,j) to each pixel (i,j), the second driving voltage (i,j) being a target driving voltage corresponding to the pixel data for the pixel (i,j) plus a second driving shift voltage assigned to the second sub-frame;

wherein the pixel data is displayed continuously during the first and second sub-frames.

11. The method according to claim 8 , wherein the display is an LCD (Liquid Crystal Display).

12. The method according to claim 8 , wherein the display is an OLED (Organic Light Emitter Diode) display.

13. The method according to claim 8 , wherein the display is a PDP (Plasma Display Panel).

14. A method for driving a display having pixels arranged in an m*n array, m and n being integers, the display receiving a frame signal for displaying a frame for a frame period, the frame signal including pixel data for each of the pixels of the display, comprising the steps of:

(a) dividing the frame period into a first sub-frame period and a second sub-frame period;
