一种OLED显示面板、其驱动方法及显示装置
摘要：
本发明公开了一种OLED显示面板、其驱动方法及显示装置，在纹路识别时间段，控制纹路识别区域内的第一发光器件处于关闭状态，第一发光器件至少包括：纹路识别区域内，与小孔成像区域的边缘间距最近的发光器件；之后，通过图像传感器获取纹路识别区域内在显示面板上方的物体经过小孔成像区域后的成像，以便实现纹路采集和识别功能。由于关闭了距离小孔成像区域最近的发光器件，使其不发光，因此，可以减少通过强反射界面的反射入射至图像传感器的发光器件的光线，从而降低了图像传感器获取纹路的图像的干扰，使采集到的纹路图像更清晰，以提高纹路识别的准确性。
摘要（英）：

The disclosure discloses an OLED display panel, a driving method thereof and a display device. In a texture recognition period, a first light emitting element in a texture recognition area is controlled to be in an off state, wherein the first light emitting element includes at least a light emitting element of which a spacing from an edge of a pinhole imaging area is closest in the texture recognition area; and then an image of an object, formed through the pinhole imaging area, is obtained by an image sensor, the object being in the texture recognition area and above the display panel, so as to implement the texture collection and recognition functions.
