Electroluminescence display panel and driving method thereof
The present invention relates to an electroluminescence display panel and a method of driving the same. The electroluminescence display panel comprises a plurality of pixels arranged in a matrix, each of the pixels including a red sub-pixel, a green sub-pixel and a blue sub-pixel. The blue sub-pixel includes at least a first blue sub-sub-pixel and a second blue sub-sub-pixel. In operation, the first blue sub-sub-pixel and the second blue sub-sub-pixel are alternately driven among frames.
1. An electroluminescence (EL) display panel comprising:
a plurality of pixels arranged in a matrix, each of the pixels including a red sub-pixel, a green sub-pixel and a blue sub-pixel, wherein the blue sub-pixel includes at least a first blue sub-sub-pixel, a second blue sub-sub-pixel, and a third blue sub-sub-pixel;
wherein the red sub-pixel, the green sub-pixel, the first blue sub-sub-pixel, the second blue sub-sub-pixel, and the third sub-sub-pixel are arranged adjacent to each other in a block configuration;
wherein during a first timing, a first combination of blue sub-sub-pixels consisting of the first and second blue sub-sub-pixels are driven together;
wherein during a second timing, a second combination of blue sub-sub-pixels consisting of the second and the third blue sub-sub-pixels are driven together;
wherein during a third timing, a third combination of blue sub-sub-pixels consisting of the first and third blue sub-sub-pixels are driven together;
wherein in operation, the first timing, the second timing, and the third timing are driven in sequence.
2. The EL display panel of claim 1 , wherein the red sub-pixel, the green sub-pixel, the first blue sub-sub-pixel, and the second blue sub-sub-pixel are arranged in this order side by side in a stripe form.
3. The EL display panel of claim 1 , wherein area of the red sub-pixel, area of the green sub-pixel, and area of the first blue sub-sub-pixel are in the ratio of about 100:110:120, and area of the red sub-pixel, area of the green sub-pixel, and area of the second blue sub-sub-pixel are in the ratio of about 100:110:120.
4. The EL display panel of claim 1 , wherein areas of the first, second, and third blue sub-sub-pixels are equal to each other.
5. The EL display panel of claim 1 , wherein area of the red sub-pixel, area of the green sub-pixel and a sum of areas of any two of the first, second and third blue sub-sub-pixels are in a ratio of about 100:110:120.
6. A method of driving an electroluminescence (EL) display panel comprising a plurality of pixels arranged in a matrix, each of the pixels including a red sub-pixel, a green sub-pixel and a blue sub-pixel, and the blue sub-pixel including at least a first blue sub-sub-pixel, a second blue sub-sub-pixel, and a third blue sub-sub-pixel, and the red sub-pixel, the green sub-pixel, the first blue sub-sub-pixel, the second blue sub-sub-pixel, and the third blue sub-sub-pixel being arranged adjacent to each other in a block configuration, the method comprising:
driving, during a first timing, a first combination of blue sub-sub-pixels consisting of the first and second blue sub-sub-pixels being driven together;
driving, during a second timing, a second combination of blue sub-sub-pixels consisting of the second and the third blue sub-sub-pixels being driven together;
driving, during a third timing, a third combination of blue sub-sub-pixels consisting of the first and third blue sub-sub-pixels being driven together;
wherein in operation, the first timing, the second timing, and the third timing are driven in sequence.
