Abstract

The invention discloses a method for manufacturing a display panel, a display panel structure, and a display device, wherein the panel structure includes: a substrate; pixel units arranged and formed on the substrate in a matrix; at least one scanning signal driving circuit formed on the substrate. on the substrate and located below the pixel unit, wherein the gate of the driving transistor of the pixel unit is connected to the output terminal of the scanning signal driving circuit through a first through hole. In the embodiment of the present invention, by arranging the scanning signal driving circuit under the pixel unit, the display panel can be narrowed and the beautification degree of the display can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of organic light-emitting display (Organic Light-Emitting Diode, OLED) device technology, and in particular, to a method for manufacturing a display panel, a structure of a display panel, and a display device. Background technique [0002] With the development of science and technology, researchers have launched research on OLED display technology. OLED is an all-solid-state device that directly converts electrical energy into light energy. It has the advantages of thinness and lightness, high contrast, fast response, wide viewing angle, and wide operating temperature range. It has attracted great attention and is considered to be a new generation of display devices. . [0003] In the prior art, most of the panel structures of OLED displays adopt such as figure 1 The structure shown includes the first scanning signal driving circuit 11, the second scanning signal driving circuit 12 and the row ...
