Organic electroluminescent device and electronic apparatus having specific sub-pixel pattern
View Patent ↗An organic electroluminescent device includes electrodes, a luminescent layer which is sandwiched between the electrodes, and which includes dots consisting of red sub-pixels, green sub-pixels, and blue sub-pixels. The sub-pixels are arranged in predetermined patterns, each of the predetermined patterns being formed such that at least one blue sub-pixel is disposed as a central pattern, the red sub-pixels are symmetrically arranged about a central point of the central pattern, and the green sub-pixels are also symmetrically arranged about the central point of the central pattern.
1. An organic electroluminescent device comprising:
electrodes; and
a luminescent layer which is sandwiched between the electrodes, and which includes dots consisting of red sub-pixels, green sub-pixels, and blue sub-pixels;
wherein the sub-pixels are arranged in predetermined patterns, each of the predetermined patterns being formed such that at least one of the blue sub-pixels is disposed as a central pattern, the red sub-pixels are symmetrically arranged about a central point of the central pattern, and the green sub-pixels are also symmetrically arranged about the central point of the central pattern, and
wherein the red sub-pixels and the green sub-pixels are commonly used in plural theoretical pixels.
2. An organic electroluminescent device according to claim 1 , wherein each of the sub-pixels is formed in a rectangular shape, and the central pattern consists of two blue sub-pixels.
3. An organic electroluminescent device according to claim 1 , wherein each of the sub-pixels is formed in a rectangular shape, and the central pattern consists of one blue sub-pixel, which is made longer than the red and green sub-pixels.
4. An organic electroluminescent device according to claim 1 ,
wherein the blue sub-pixels are formed in a square shape, and the central pattern consists of one blue sub-pixel, and
wherein each of the predetermined patterns is formed in a substantially square shape, and is formed such that each of the red and green sub-pixels is disposed adjacent to one of sides of the square-shaped blue sub-pixel.
5. An electronic apparatus comprising the organic electroluminescent device according to claim 1 .
6. An organic electroluminescent device according to claim 1 , wherein the red sub-pixels and the green sub-pixels are commonly used in at east five theoretical pixels.
7. An organic electroluminescent device according to claim 1 , wherein the theoretical pixels include:
four sub-pixels arranged in a first direction; and
two sub-pixels respectively disposed on both sides in a second direction with respect to one sub-pixel among the four sub-pixels.
