    Abstract: The present disclosure discloses a method for executing an operation action on a display screen and a device for executing an operation action. Firstly, a gazing position of an operator's eyes on the display screen and a corresponding operation position of the operator's operating portion on the display screen are determined, then a corresponding operation is executed for content displayed on the display screen according to the operation action of the operating portion, when it is determined that the gazing position of the operator's eyes on the display screen is consistent with the corresponding operation position of the operator's operating portion on the display screen. Therefore, the method needs to not only determine the corresponding operation position of the operator's operating portion on the display screen, but also determine the gazing position of the operator's eyes on the display screen, and the corresponding operation is executed for the content displayed on the display screen according to the operation action of the operating portion only when the two positions are consistent with each other.

    Abstract: Disclosed in the present disclosure are an OLED display panel, a driving method therefor and a display device. A first light-blocking layer is disposed between a photosensitive unit and an organic electroluminescent structure, and the first light-blocking layer at least has a hollow area corresponding to a fingerprint identification area. When a finger touches a screen, the lights emitted by the organic electroluminescent structure are reflected by the finger to irradiate the photosensitive unit through small holes, such that fingerprint information of the finger is detected due to the brightness differences among the lights reflected by ridges and valleys of the finger. The small holes in the hollow area can function to improve the light intensity convergence, thus increasing the sensitivity to finger touches to the greatest extent.
