Description

TECHNICAL FIELD Embodiments of the present disclosure relate to a pixel arrangement structure and a display device. BACKGROUND With the diversified development of application fields and product forms of organic light-emitting diode (OLED) display devices, the demand for electronic products having organic light-emitting diode display devices is also increasing. These electronic products include smartphones, TVs, computers, tablets, navigators, car central control screens, and smart watches. Organic light-emitting diode (OLED) display devices include driving substrates, organic light-emitting elements and encapsulation layers; each of the organic light-emitting elements includes an anode, a cathode and an organic light-emitting layer located between the anode and the cathode; each of the organic light-emitting elements is located on a driving substrate and connected with a pixel driving circuit on the driving substrate; each of the encapsulation layers is located on a side of the organic light-emitting element away from the driving substrate, so that the organic light-emitting element is packaged to prevent water and oxygen corrosion from causing deterioration of the organic light-emitting element. In an organic light-emitting diode (OLED) display device, organic light-emitting elements can be arranged in an array on the driving substrate and serve as sub-pixels. A light-emitting layer of the organic light-emitting element is usually formed by evaporating organic light-emitting material at a corresponding position through a fine metal mask (FMM), therefore, an opening size of the fine metal mask directly determines sizes of the sub-pixels. Due to limitations in a manufacturing process of the fine metal mask, the opening size cannot be further reduced, it is difficult to obtain an organic light-emitting diode (OLED) display device with high resolution by using a conventional pixel arrangement structure. SUMMARY Embodiments of the present disclosure provide a pixel arrangement structure and a display device including the pixel arrangement structure. The pixel arrangement structure can be modulated by modulating positions of sub-pixels of different colors, distribution of virtual pixels (or white point pixels) can be made more uniform, thus display problems such as “distortion” and “graininess” caused by the human eyes can be solved, and a better display effect can be achieved.
