Problems solved by technology

[0005] In view of this, the embodiments of the present invention provide an organic light-emitting display panel and a display device to solve the problem that both the driving transistor and the enabling switching transistor adopt a top-gate structure in the prior art, so that it is impossible to ensure that the driving transistor has a large sub- Threshold swing and relatively small carrier mobility requirements, by driving the net transistor and enabling the switch to adopt a differentiated TFT structure, so as to ensure the realization of the characteristic requirements of the driving transistor

Abstract

According to the embodiment, the invention provides an organic light-emitting display panel and a display device. The organic light-emitting display panel comprises a driving unit and a light-emittingunit which is arranged in correspondence to the driving unit, wherein the driving unit comprises a switching transister and a driving transister; the switching transister comprises a first grid, a first source, a first drain and a first active layer; the driving transister comprises a second grid, a second source, a second drain and a second active layer; the first active layer and the second active layer are formed by patterning a same semiconductor layer; the first grid is formed by patterning a first metal layer; the second grid is formed by patterning a third metal layer; the first metallayer is arranged at the side, close to the light-emitting unit, of the semiconductor layer; and the third metal layer is arranged at the side, away from the light-emitting unit, of the semiconductorlayer.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel and a display device. 【Background technique】 [0002] Among human sensory organs, the visual organ (eye) receives the most information. In production and life, people need to use more and more rich visual information, so display technology plays a very important role in today's human society. Since the emergence of display technology, technological development has also been very rapid. Cathode ray tube technology (CRT), plasma display (PDP), liquid crystal display (LCD), and even the latest OLED display and micro LED display technologies have appeared successively. [0003] With the development of society and the continuous improvement of human needs for material life, today's display technology is moving towards narrow borders, high contrast, high resolution, full-color display, low power consumption, high reliability, long life...
