Abstract

The embodiment of the invention provides an organic light emitting display panel. The organic light emitting display panel comprises a display area and a non-display area surrounding the display area;the display area is provided with pixel rows which extend in a first direction and are distributed in a second direction; the non-display area is provided with scanning driving circuits and light emitting control circuits; each scanning driving circuit comprises cascaded scanning driving circuit units; each light emitting control circuit comprises cascaded light emitting control circuit units; the first-stage scanning driving circuit units drive two pixel rows; the first-stage light emitting control circuit units drive n pixel rows, and n is an even number greater than or equal to 4. By meansof the organic light emitting display panel, the first-stage scanning driving circuit units and the light emitting control circuit units drive multiple rows, the number of stages of the scanning driving circuit units and the light emitting control circuit units is reduced, a bezel occupied by the driving circuits is reduced, and the narrow bezel can be achieved.

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 rapid development of display technology, consumers have higher and higher requirements for the screen-to-body ratio of display devices. More and more consumers are willing to purchase full-screen display devices. However, due to the drift of the threshold voltage of the transistor during use, the driving current deviates from the preset value. Therefore, the pixel driving circuit is required to compensate the drift of the threshold voltage of the driving transistor. The pixel drive circuit needs to be jointly controlled by a scan drive signal and a light emission control signal. Therefore, in the prior art, a scan driving circuit and a light emitting control circuit are arranged in the left and right frame regions of the organic light emitti...
