Abstract

The invention provides a display substrate, a manufacturing method thereof, and a display device. The display substrate includes a display area arranged on the substrate, and at least one PMOLED is included in the bending area of ​​the display area. Since the PMOLED is not driven by a thin film transistor, it effectively avoids the impact of the electrical change caused by the bending of the thin film transistor. The influence of display performance, further, an organic insulating layer is included between the substrate and the first OLED unit, and the organic insulating layer includes an organic material. Since the organic material has good strain elasticity compared to the inorganic material, The bending resistance of the bending area can be improved. The display lifespan of the display area can be effectively improved by using the manufacturing method of the display substrate provided by the present invention. The display device provided by the present invention comprising the above display substrate includes at least one PMOLED in the bending area of ​​the display area, which can avoid display performance changes caused by bending of thin film transistors.

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...
