The invention provides an organic light-emitting display panel and an organic light-emitting display device, which are used to solve the problem of deterioration of display uniformity of a display device integrated with a fingerprint recognition function. The organic light-emitting display panel provided by the present invention includes a display area and a non-display area, wherein the display area includes a fingerprint identification area, the display pixels located in the display area are arranged in an array, and at least a part of the plurality of display pixels is located in the fingerprint identification area, The fingerprint identification area also includes at least one fingerprint identification pixel. The fingerprint identification pixel is located in one row of display pixels and between two adjacent columns of display pixels. At most one control signal line is set corresponding to one row of display pixels, and the control signal The lines are electrically connected to the fingerprint recognition pixels located in the same display pixel row, and the signals transmitted through the control signal lines control the fingerprint recognition pixels to emit light. By using the fingerprint recognition pixels as the fingerprint recognition light source, the accuracy of fingerprint recognition will not be affected while display uniformity is improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel and an organic light emitting display device. Background technique [0002] With the development of display technology, in order to meet the needs of users for a higher screen-to-body ratio (the ratio of the area of the display area to the area of the display panel where it is located) and improve the user's visual impression, in the display device with integrated fingerprint recognition function, Usually, the fingerprint identification functional device is arranged in the display area of the display panel to increase the screen ratio. [0003] However, in the prior art, a display device integrated with a fingerprint identification display function often suffers from the problem of degraded display uniformity. Contents of the invention [0004] In view of this, the present invention provides an organic light emitting d...
