Abstract: An OLED array substrate is provided. The OLED array includes multiple sub-pixels defined by multiple data lines and multiple scan lines, and a resistance-type pressure sensing element located in non-opening regions of the sub-pixels. The pressure sensing element includes multiple resistors. Each resistor has a serpentine wire structure. The serpentine wire structure includes a first sub-wire and a second sub-wire connected to two adjacent first sub-wires. Both the first sub-wire and the second sub-wire are located in non-opening regions of the sub-pixels on the OLED array substrate. The resistance-type pressure sensing element is arranged in a display region of the OLED array substrate without influencing the display effect of a display panel or a display device. An extension direction of a projection of the first sub-wire on an array substrate intersects with extension directions of projections of the data lines and the scan lines on the array substrate.
