Abstract

The invention provides a display substrate and a manufacturing method thereof, and a display apparatus. The display substrate comprises a display region on a substrate; a bending region in the displayregion comprises at least one PMOLED; the PMOLED is not driven by a thin film transistor, so that influence to the display performance caused by electrical performance change due to bending of the thin film transistor can be avoided effectively; furthermore, an organic insulating layer is included between the substrate and a first OLED unit; and the organic insulating layer comprises an organic material. Compared with an inorganic material, the organic material has high strain elasticity, so that the bending resistance of the bending region can be improved; and by adoption of the manufacturing method of the display substrate provided by the invention, the display service life of the display region can be prolonged effectively. According to the display apparatus comprising the display substrate provided by the invention, the bending region in the display region comprises at least one PMOLED, so that display performance change caused by bending of the thin film transistor can be avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) is also known as organic electroluminescence, organic electro-laser display or organic light-emitting semiconductor. OLED display technology has the advantages of self-illumination, wide viewing angle, high contrast, low energy consumption and thinning. , has received more and more attention. [0003] According to different driving methods, OLED can be divided into two types: PMOLED (Passive Matrix OLED, passively driven organic light emitting diode) and AMOLED (Active Matrix OLED, actively driven organic light emitting diode). Taking a display array (which may include multiple display units arranged in an array) on a glass substrate as an example, electrodes of the same nature in the same row of display units...
