Abstract

The embodiment of the invention discloses an OLED (Organic Light Emitting Diode) display device and a manufacturing method thereof. The OLED display device comprises a substrate, a plurality of OLED devices and a plurality of spacers, the plurality of OLED devices are arranged on the substrate, and one side, far away from the substrate, of at least part of the OLED devices is provided with an inorganic layer; and at least part of the spacers are distributed in gaps between the OLED devices. The OLED display device provided by the invention is provided with the spacer, so that the problem that the display quality of the OLED display device is reduced due to external impact is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display device and a manufacturing method thereof. Background technique [0002] An organic light-emitting display device (Organic Light-Emitting Display, OLED) is a self-luminous device with a series of advantages such as high brightness, full viewing angle, fast response speed, and flexible display. Organic light-emitting diode display devices can be divided into passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED) according to the driving method. AM display devices have higher luminous efficiency and can be used as high-resolution High-efficiency large-size display device. [0003] When making large-sized top-emitting organic light-emitting substrates, the traditional glass glue packaging method is no longer applicable due to stress problems, etc. Large-sized top-emitting organic light-emitting substrates are...
