Problems solved by technology

It has the advantages of fast response, high contrast, wide color gamut, and energy saving. It is the mainstream direction of OLED technology development. However, each low-temperature polysilicon thin film transistor has at least a large number of peripheral leads such as gate drive and source-drain drive.
However, these lead areas cannot emit light, resulting in a black area of ​​a certain width that cannot display images in the final display device, that is, the frame area of ​​the display panel, resulting in the inability of the display panel to achieve narrower borders.

Abstract

The invention provides an array substrate and a preparation method thereof and a display device, and belongs to the technical field of display, and can solve the problems that existing display devices have relatively wide bezels. The array substrate comprises a display area and a surrounding area which surrounds the display area. The display area is provided with multiple active organic light-emitting diodes. The array substrate also comprises multiple passive organic light-emitting diodes which are arranged in the surrounding area. The active organic light-emitting diodes and the passive organic light-emitting diodes are electrically connected with a power supply driving unit. According to the array substrate, multiple passive organic light-emitting diodes capable of emitting light are arranged in the surrounding area so that bezel narrowing of the array substrate can be realized.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an array substrate, a preparation method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) device, as a new type of flat-panel display, has received more and more attention due to its characteristics of active light emission, high luminous brightness, wide viewing angle, fast response speed, low energy consumption and flexibility. The more attention is paid to the next generation display technology that may replace liquid crystal display. OLED is divided into active drive (AM-OLED) and passive drive (PM-OLED) according to the driving method. [0003] The typical structure of PM-OLED is composed of glass substrate, ITO (indium tin oxide; indium tin oxide) anode (Anode), organic light-emitting layer (EmittingMaterialLayer) and cathode (Cathode), etc. It has simple structure, few driving leads, and peripheral circuits Fea...
