Description
Technical Field
The present invention relates to the field of light emitting diode display technologies, and in particular, to a pixel array and a driving method.
Background
Among the flat panel display technologies, an Organic Light-Emitting Diode (OLED) display is considered as a third generation display technology following a Liquid Crystal Display (LCD) due to its advantages of lightness, thinness, active Light emission, fast response speed, wide viewing angle, rich colors, high brightness, low power consumption, high and low temperature resistance, etc. According to the driving method, the OLED is classified into a Passive OLED (PMOLED) and an Active OLED (AMOLED), the PMOLED is also called a Passive Matrix OLED, and the AMOLED is also called an Active Matrix OLED, wherein the PMOLED can only manufacture a small-sized and low-resolution display panel, and the AMOLED is driven by integrating a Thin Film Transistor (TFT) and a capacitor in each pixel and maintaining a voltage by the capacitor, so that a large-sized and high-resolution panel can be realized, which is the focus of current research and the development direction of future display technologies.
However, as the PPI increases, the Pixel Size of the corresponding Pixel unit decreases. When the Pixel Size decreases, the pitch of the corresponding same-color pixels will decrease continuously. Because the opening on the metal mask plate is only opened with the same color, and the distance between pixels with the same color is continuously reduced, the distance between the openings of the metal mask plate is reduced. Therefore, when the PPI is higher, the distance between the corresponding metal mask plates is smaller, the manufacturing difficulty of the metal mask plates is higher, and even the metal mask plates cannot be manufactured correspondingly.
Disclosure of Invention
The invention provides a pixel array and a driving method, which are used for solving the problem that in the prior art, when the PPI is higher, the distance between corresponding metal mask plates is smaller, and the manufacturing difficulty of the metal mask plates is higher.
The embodiment of the invention provides a pixel array, wherein a first sub-pixel, a second sub-pixel, a third sub-pixel, a fourth sub-pixel, a fifth sub-pixel and a sixth sub-pixel are sequentially arranged in any four adjacent pixel units in a first direction; the first sub-pixel, the second sub-pixel and the third sub-pixel are sub-pixels with different colors, the first sub-pixel and the fourth sub-pixel are sub-pixels with the same color, the second sub-pixel and the fifth sub-pixel are sub-pixels with the same color, and the third sub-pixel and the sixth sub-pixel are sub-pixels with the same color;

In the embodiment of the invention, as six sub-pixels are sequentially arranged in any four adjacent pixel units in the first direction and can simultaneously emit light under the control of the driving circuit, compared with the prior art, the opening interval between the sub-pixels in the same color is increased, the light emitting effect of the sub-pixels is ensured, and the problems that the higher the PPI is, the smaller the distance between the corresponding metal mask plates is, and the greater the manufacturing difficulty of the metal mask plates in the prior art are effectively solved.
Further, the first sub-pixel, the second sub-pixel, and the third sub-pixel are sequentially arranged in any adjacent three pixel units in a second direction of the pixel array, and one sub-pixel is arranged in each pixel unit.
In the embodiment of the invention, in order to prevent color cast of edge pixels of the pixel arrangement and convenience of wiring of each pixel row, different sub-pixels are arranged in each pixel unit in the second direction of the pixel arrangement.
Further, the pixel array has the same sub-pixels in a pixel unit in the second direction.
In the embodiment of the present invention, in order to enable easier pixel arrangement, the first pixel rows may be repeatedly arranged in the second direction of the pixel arrangement, and the direction of the first pixel rows may be the first direction.
Further, an included angle between the second direction and the first direction is 90 degrees.
In the embodiment of the invention, the first direction and the second direction are vertically arranged, so that pixel display can be better carried out.
Further, the first sub-pixel, the second sub-pixel and the third sub-pixel are located in a first adjacent pixel unit; the fourth sub-pixel, the fifth sub-pixel and the sixth sub-pixel are positioned in a second adjacent pixel unit; the first adjacent pixel unit is two adjacent pixel units in the four adjacent pixel units; the second adjacent pixel unit is another two adjacent pixel units in the four adjacent pixel units;
the arrangement mode of each sub-pixel in the first adjacent pixel unit is the same as that of each sub-pixel in the second adjacent pixel unit.
In the embodiment of the invention, in order to ensure that the light emitting effect of each sub-pixel in the pixel row is optimal, three sub-pixels are arranged in two pixel units.
Further, the first sub-pixel, the second sub-pixel, the third sub-pixel, the fourth sub-pixel, the fifth sub-pixel and the sixth sub-pixel are arranged in equal intervals in the four adjacent pixel units.
In the embodiment of the invention, in order to ensure that the light emitting effect of each sub-pixel in the pixel row is optimal, the intervals between each sub-pixel are equal.
Further, the size of each sub-pixel is the same.
In the embodiment of the invention, in order to ensure that the light-emitting effect of each sub-pixel in the pixel row is optimal, the sizes of the sub-pixels are the same.
