Benefits of technology
The proposed pixel structure increases pixel density, enabling higher PPI and achieving full color display with improved uniformity and reduced manufacturing complexity, effectively addressing the limitations of conventional OLED display technologies.
Problems solved by technology
In a conventional side-by-side arrangement for RGB pixels, only 200-300 PPI can be reached, which is difficult to achieve a high-resolution display effect.
With the increasing demand of users for the resolution of OLED display devices, such a side-by-side arrangement for RGB pixels can no longer meet design requirements of high PPI products.
However, in this arrangement, each of the sub-pixels of R and B is shared by the adjacent pixels, and a distortion may exist in an entire display effect, so that this is not a full color display in a true sense.

Embodiment Construction
[0039]The inventor of this disclosure found, through a research, that a conventional arrangement for RGB pixels can no longer meet requirements on both an opening ratio and a display effect of a product. Therefore, a pixel structure of an OLED display device is provided. The pixel structure includes a plurality of pixel units arranged in a matrix form. Each of the pixel units includes two pixel subunits that are adjacently arranged along a first direction and each of the pixel subunits includes three sub-pixels having different colors. One pixel subunit includes a first sub-pixel, a second sub-pixel, and a third sub-pixel or a second sub-pixel, a first sub-pixel, and a third sub-pixel that are sequentially arranged along a second direction, and the other pixel subunit includes a third sub-pixel, a first sub-pixel, and a second sub-pixel or a third sub-pixel, a second sub-pixel, and a first sub-pixel that are sequentially arranged along the second direction.
[0040]The two pixel subuni...

Abstract
A pixel structure, an Organic Light-Emitting Diode (OLED) display device, and a driving method. The pixel structure includes a number of pixel units arranged in a matrix form. Each pixel unit includes two pixel subunits adjacently arranged along a first direction and includes three sub-pixels having different colors. The two pixel subunits constitute two pixels adjacently arranged along the second direction. A distance between centers of two sub-pixels having a same color in two pixels not adjacent in three consecutive pixels in the second direction is 2 or 2N / (N+1) times of a distance between the centers of two sub-pixels having the same color in two adjacent pixels in the first direction. N is an integer greater than or equal to 1.
Description
TECHNICAL FIELD[0001]The present disclosure relates to the field of display technologies, and particularly, to a pixel structure, an OLED display device including the pixel structure and a driving method for the pixel structure.BACKGROUND[0002]Organic Light-Emitting Diode (OLED) is an active light-emitting device. Compared with the conventional Liquid Crystal Display (LCD), an OLED display technology requires no backlight and has self-illuminating properties. The OLED uses a relatively thin organic material film layer and a glass substrate. When a current passes, the organic material emits light. Therefore, OLED display screen can significantly save electric energy, can be fabricated lighter and thinner, withstand a wider range of temperature variations than LCD display screen, as well as have a larger viewing angle. The OLED is expected to become the next generation flat panel display technology after the LCD, and is one of the most popular technologies in flat panel display techno...
