Description
Technical Field
The invention relates to the technical field of light emitting diode display, in particular to a pixel array.
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, the existing OLED is difficult to meet the requirements of electronic devices for high resolution and high brightness of display screens, because RGB uses their own materials, and the luminous efficiencies of the corresponding materials are different. The material of color B has the worst luminous efficiency. When the resolution of the OLED in the prior art reaches high PPI (pixel per inch), the smaller the compressed openings of the R color and the G color on the corresponding metal mask plate can not be made, and finally the pixel PPI of the OLED is limited.
In summary, the prior art fails to provide a pixel array that is suitable for high resolution OLEDs.
Disclosure of Invention
The invention provides a pixel array, which is used for solving the problem that R color and G color can not be manufactured when the resolution of an OLED in the prior art reaches more than 300PPI (pixel per inch) and the openings of the corresponding metal mask plate are compressed to be smaller.
Embodiments of the present invention provide a pixel array,
the pixel array comprises a first pixel group and a second pixel group, wherein the first pixel group comprises at least two first sub-pixels and one second sub-pixel which are arranged in series, and the second pixel group comprises at least two third sub-pixels and one second sub-pixel which are arranged in series;

Further, each second sub-pixel in the pixel array is arranged along a second direction, and the second direction is not parallel to the first direction.
In the embodiment of the invention, the second sub-pixels are arranged along the second direction, so that the openings of the second sub-pixels can be conveniently and regularly manufactured on the metal mask plate.
Further, four sub-pixels adjacent to any one of the second sub-pixels in the first direction form a parallelogram, and the sub-pixels of adjacent vertexes of the parallelogram are different sub-pixels.
