Problems solved by technology

This is because, if the height of the glass frit does not decrease, the height of the glass frit on the left and right sides of the organic light emitting diode packaging structure is relatively large, while the height of PS in the middle is relatively small, and the transparent substrate will be lifted to form a certain curved arc. In this way, the transparent substrate The Newton ring effect will be generated between the array substrate and the array substrate, which will affect the picture quality of the final display device.
However, due to the limitation of the characteristics of the glass frit itself, it is impossible to make it very thin, and the glass frit must ensure a sufficient height to maintain the packaging requirements

Abstract

The invention provides an AMOLED display panel and an AMOLED display device. The AMOLED display panel comprises an array substrate, a transparent substrate arranged opposite to the array substrate, and a frit connecting the array substrate and the transparent substrate, wherein a plurality of supporting columns are arranged between the array substrate and the transparent substrate, each supporting column is formed by laminating at least two layers of branch supporting columns, and at least one layer of branch supporting column is made of electrostrictive materials; and electrodes are arranged at the top part and the bottom part of each supporting column, an electric field is formed between the two electrodes, and the height of the branch supporting column made of the electrostrictive materials is controlled through controlling intensity of the electric field, so that the total height of the branch supporting columns is matched with that of a sealing material. The AMOLED display panel and the AMOLED display device solve the Newton's ring effect, improve the image quality and yield of the display panel, and reduce process cost.

Description

technical field [0001] The invention relates to the field of flat panel display, in particular to an AMOLED display panel and a display device thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) display, also known as Organic Electroluminescence Display (OLED), has good color contrast, active light emission, wide viewing angle, thinness, fast response speed and low energy consumption And other advantages, it is recognized as the most promising display technology. [0003] In the manufacturing process of the OLED display, the array substrate and the transparent substrate are usually manufactured separately first, and then the two substrates are bonded together by glass frit (Frit) coated on the transparent substrate as an encapsulation material, that is, a box is formed. In order to make the transparent substrate have a certain pressure resistance, in the prior art, a plurality of PSs (photo spacers, pillars) are usually fabricated on the array substra...
