The present invention relates to a curved display field, and more particularly to a display device and a pixel structure thereof.
With the development of science and technology, more and more interaction occurs between humans and devices, and the display panel is becoming more and more important as an interface between humans and devices. How to obtain a panel possessing high light transmittance, low power consumption, high color gamut and high resolution rate has become the point of engineers of all major panel manufacturers who are constantly pursuing research.
For solving the aforesaid problem, the present invention provides a display device and a pixel structure thereof, which can improve light transmittance and color gamut to promote display result.
An objective of the present invention is to provide a pixel structure, comprising a plurality of pixel units arranged in an array, wherein each of the pixel units comprises three sub pixels, and the three sub pixels are respectively used to display three colors of red, green and blue, and each of the sub pixels comprises a bent portion, and bent portions of sub pixels on a same row have a same bent direction.
Optionally, the bent portions of the sub pixels on an odd row are bent in a first direction, and the bent portions of the sub pixels on an even row are bent in a second direction, and the first direction is opposite to the second direction.
Optionally, the bent portions are in a fold line shape.
Optionally, the bent portions are in a curved shape.
Optionally, arrangements of the three sub pixels in the pixel unit on the odd row are the same, and arrangements of the three sub pixels in the pixel unit on the even row are the same.
Optionally, the arrangements of the three sub pixels in the pixel unit on the odd row are different from the arrangements of the three sub pixels in the pixel unit on the even row.
Optionally, any two adjacent sub pixels display different colors.
Optionally, the sub pixels on the odd row are aligned with the sub pixels on the even row.
Optionally, the sub pixels on the odd row are offset from the sub pixels on the even row.
The present invention further provides a display device. The display device comprises any one of the aforesaid pixel structures.
In the provided pixel structure, each sub pixel includes a bent portion. The bent portions of the sub pixels on the same row are the same bent direction. Since the sub pixels include bent portions, the color distribution of the pixel structure in different directions can be made more uniform, thereby improving light transmittance and color gamut to promote display result.
Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention may be embodied in various different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, these embodiments are provided to explain the principles of the present invention and the practical application thereof to thereby enable those of ordinary skill in the art to understand the various embodiments of the present invention and the various adaptations for the specific intended application. In the drawings, the same reference numerals will be used to refer to the same elements throughout.

Each row of the pixel structure comprises at least one pixel unit 1, and the bent directions of the bent portions 100 of the sub pixels 10 on different rows may be the same or different. Preferably, the bent portions 100 of the sub pixels 10 on an odd row have the same bent direction, and the bent portions 100 of the sub pixels 10 on an even row have the same bent direction, and the bent direction of the bent portions 100 of the sub pixels 10 on the odd row is different from the bent direction of the bent portions 100 of the sub pixels 10 on the even row.
Specifically, the bent portions 100 of the sub pixels 10 on the odd row are bent in a first direction, and the bent portions 100 of the sub pixels 10 on the even row are bent in a second direction, and the first direction is opposite to the second direction. Here, it means that the bent portions 100 of the sub pixels 10 on the odd row are bent toward the right, and the bent portions 100 of the sub pixels 10 on the even row are bent toward the left.
The sub pixels 10 comprise the bent portions 100. Thus, the color distribution of the pixel structure in different directions can be made more uniform. Besides, by arranging the bent directions of the bent portions 100 of the sub pixels 10 on different rows to be different, the color distribution of the pixel structure in different directions can be made more uniform in advance.
The bent portions 100 can be in a fold line shape. As shown in
The sub pixels 10 on the odd row are aligned with the sub pixels 10 on the even row. Namely, for the same column, the parallel sides of the sub pixel 10 located on different rows are aligned with each other. For the same column, a projection of the two parallel sides of the sub pixel 10 on the odd row are coincident with a projection the two parallel sides of the sub pixel 10 on the even row in the x-axis. For the same column, a projection of the bent point of the two folded sides of the sub pixel 10 on the odd row and a projection of the bent point of the two folded sides of the sub pixel 10 on the even row are symmetrical about a central axis of the sub pixels 10 on the column.
The arrangements of the three sub pixels 10 in the pixel unit 1 on the odd row are the same, and the arrangements of the three sub pixels 10 in the pixel unit 1 on the even row are the same. The arrangements of the three sub pixels 10 in the pixel unit 1 on the odd row are the same as the arrangements of the three sub pixels 10 in the pixel unit 1 on the even row. As shown in

For the same column, a projection of the center of the circles where the two curves are of the sub pixel 10 on the odd row and a projection of the centers of the circles where the two curves are of the sub pixel 10 on the even row are symmetrical about a central axis of the sub pixels 10 on the column.

Besides, in this embodiment, the arrangements of the three sub pixels 10 in the pixel unit 1 on the odd row are the same, and the arrangements of the three sub pixels 10 in the pixel unit 1 on the even row are the same. The arrangements of the three sub pixels 10 in the pixel unit 1 on the odd row are different from the arrangements of the three sub pixels 10 in the pixel unit 1 on the even row. The first row and the second row are illustrated. Starting from the left of the first row, the sub pixels 10 in each pixel unit 1 are respectively used to display three colors of R, G and B. Similarly, starting from the left of the second row, the sub pixels 10 in each pixel unit 1 are respectively used to display three colors of B, G R, or B, R, G, or G, B, R, or G, R, B.
Preferably, in order to make the color distribution of the entire pixel structure more uniform, any two adjacent sub pixels display different colors. The first row and the second row are illustrated. Starting from the left of the first row, the sub pixels 10 in each pixel unit 1 are respectively used to display three colors of R, G and B. Starting from the left of the second row, the sub pixels 10 in each pixel unit 1 are respectively used to display three colors of G, B and R (as shown in
In this embodiment, the pixel unit 1 can also comprise three sub pixels 10 on different rows. As an illustration shown in
The display device in this embodiment may be an LCD or an OLED. Other structures of the display device except the pixel structure are the same as those of the existing display device, and the description will not be repeated here.
