Abstract

The invention provides a screen screen, a packaging method, a display panel and a display device. The screen screen includes a frame, a screen fixed on the frame, and a shielding film arranged on the screen. The part of the screen that is not blocked by the shielding film forms a printing area, and a shielding line is arranged in the printing area, and the shielding line is arranged along the edge of the shielding film, and the width of the shielding line is larger than that of the screen The width of the grid lines. When the encapsulant is printed on the substrate to be printed through the screen screen, the encapsulant in the printing area corresponding to the shielding line is less than the encapsulant in the printing area on both sides of it, so that the appearance of the formed encapsulant is: shielding The height of the encapsulant in the area where the line is located is lower than the height of the encapsulant on both sides, and the formed encapsulant has at least two retaining walls, which can form secondary protection or multiple protections for the display panel to achieve a better encapsulation effect. The corrosion resistance of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a silk screen, a packaging method, a display panel and a display device. Background technique [0002] Existing display devices, such as TFT-LCD (Thin Film Transistor-Liquid Crystal Display) or OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display devices, generally include an upper substrate and a lower substrate, and an upper substrate and a lower substrate. The substrate is bonded by encapsulation glue in the encapsulation area. At present, the encapsulation glue is generally formed on the upper substrate or the lower substrate by screen printing, and then the upper substrate and the lower substrate are attached correspondingly to be bonded together. Because display devices have high requirements on encapsulation effects, especially OLED display devices, organic layers that are extremely sensitive to water vapor and oxygen exist in OLED display devices. I...
