Description
Technical Field
The present application relates to the field of display technologies, and in particular, to a pixel arrangement structure, a display panel, and a display device.
Background
Organic Light-Emitting diodes (OLEDs) are considered as a new application technology for next-generation flat panel displays because of their self-luminescence, no need of backlight source, high contrast, thin thickness, wide viewing angle, fast response speed, applicability to flexible panels, wide temperature range, and simple structure and process.
In the manufacturing process of the OLED, an FMM (Fine Metal Mask) is generally used as a vapor deposition Mask plate, and a light-emitting material is vapor deposited to form a light-emitting layer. The open area of the vapor mask plate corresponds to the deposition area of the light emitting material in one sub-pixel, and a smaller open area means that the sub-pixel can be made smaller, and accordingly, a smaller pixel can be obtained, so that the higher the PPI (Pixels Per inc, the number of Pixels Per Inch), the higher the resolution and the higher the accuracy.
Therefore, in order to reduce the opening area of the mask for evaporation to improve the PPI, the OLED pixel structure is formed in the arrangement manner as shown in fig. 1 or in the arrangement manner as shown in fig. 2. As can be seen from fig. 1 and 2, G pixels or B pixels are linearly arranged, so that a Slit opening method is required to be used for manufacturing the evaporation mask plate of the OLED, and after the Slit opening method is applied to an OLED display panel with a high PPI, the distance between adjacent openings on the evaporation mask plate can be reduced, and the metal strip is thin. The thin metal strip is easily influenced by the magnetic force line direction of the magnet plate to deform in the use process of the vapor plating mask plate, so that different color materials among sub-pixels are polluted mutually to cause color mixing, the production yield of a product is low, meanwhile, the utilization rate of an effective vapor plating area is low, the pixel aperture ratio is low, and the FMM manufacturing process difficulty is high.
Therefore, how to effectively improve the aperture ratio of the pixel while ensuring the reduction of the opening area of the evaporation mask is a technical problem to be solved by those skilled in the art.
