The present invention provides an organic light emitting display panel and an organic light emitting display device for solving the problem of display uniformity degradation of the display device integrated with a fingerprint recognition function. The organic light emitting display panel provided by the present invention comprises a display area and a non-display area, wherein the display area comprises a fingerprint identification area; the display pixels located in the display area are arranged in an array, and at least part of a plurality of the display pixels are located in the fingerprintidentification area; the fingerprint identification area further comprises at least one fingerprint identification pixel, wherein the fingerprint identification pixel is located in one row of the display pixel rows and is located between the two adjacent columns of display pixel columns; at most one control signal line is arranged corresponding to one row of the display pixel row, and the controlsignal line is electrically connected with the fingerprint identification pixel located in the same display pixel row; and the fingerprint identification pixel is controlled to emit light by controlling the signal transmitted by the control signal line. By using the fingerprint identification pixel as a fingerprint identification light source, the accuracy of fingerprint recognition is improved without affecting the display uniformity.
Description
technical field [0001] The present invention relates to the field of display technology, and 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 user's demand for a higher screen 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 favor, in the display device with integrated fingerprint recognition function, Usually, the fingerprint recognition function device is arranged in the display area of the display panel to increase the screen ratio. [0003] However, in the prior art, the display device integrated with the fingerprint recognition display function often suffers from the problem of deterioration of display uniformity. SUMMARY OF THE INVENTION [0004] In view of this, the present invention provides an organic light-emitting display pan...
