OLED (organic light-emitting diode) display screen, manufacturing method for same and display device

Abstract

The invention discloses an OLED (organic light-emitting diode) display screen, a manufacturing method for the same and a display device, and aims to lower the debugging difficulty of an OLED display screen production process and improve the production efficiency and the quality of a product. The OLED display screen comprises a first substrate, a second substrate, first surrounding dam rubber, second surrounding dam rubber, an OLED device, a protective layer and filling rubber, wherein the first and second substrates are opposite to each other; the first surrounding dam rubber is connected between the first and second substrates, and is provided with at least one opening; the second surrounding dam rubber is connected between the first and second substrates, and is positioned outside the first surrounding dam rubber; the second surrounding dam rubber, the first substrate and the second substrate form a sealed box; the OLED device is positioned on the inner side of the first surrounding dam rubber, is positioned on the first substrate, and is covered by the protective layer; the protective layer is in sealed connection with the first substrate; the filling rubber is filled on the inner side of the first surrounding dam rubber. According to the OLED display screen, the manufacturing method for the same and the display device, the process error range of the filling volume of the filling rubber is widened, the debugging difficulty of the production process is lowered, and the production efficiency and the quality of the product are favorably improved.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to an OLED display screen, a manufacturing method of the OLED display screen and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode, referred to as OLED) display because of its thin, light, wide viewing angle, active light emission, continuously adjustable luminous color, low cost, fast response speed, low energy consumption, and driving voltage The advantages of low temperature, wide operating temperature range, simple production process, high luminous efficiency and flexible display have been listed as the next generation display technology with great development prospects. [0003] Studies have shown that components such as water vapor and oxygen in the air have a great impact on the life of OLED devices in OLED displays. This is because: OLED devices need to inject electrons from the cathode during operation, which ...
