Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] In the related art, the preparation process of the OLED display device includes: figure 1 As shown, the OLED substrate 01 is coated with a filler (Filler) 10, and then the encapsulation substrate 02 is attached to the filler 10, and then the filler 10 is cured, so as to realize the encapsulation of the OLED substrate 01. In the case where the light-emitting layer of an OLED display device (also called a WOLED display device) emits white light, such as ...

Abstract

Embodiments of the present invention provide an encapsulation substrate and a preparation method thereof, an OLED display device and a preparation method thereof, which relate to the field of display technology and can improve the problem of incomplete curing of a filling glue. The packaging substrate includes: a base substrate, a color photoresist pattern arranged on the base substrate, and a black matrix pattern for separating the color photoresist patterns; An alignment layer and a light-shielding layer on the substrate; the light-shielding layer includes liquid crystal; wherein, the alignment layer is used to align the long axes of the liquid crystal molecules in a direction perpendicular to or parallel to the base substrate. Used to cure fillers.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an encapsulation substrate and a preparation method thereof, an OLED display device and a preparation method thereof. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display device has become a very competitive and A class of display devices with good development prospects. [0003] An OLED display device includes an anode, a cathode, and a light-emitting layer. When a voltage is applied to the anode and the cathode, the light-emitting layer will emit light. Currently, there are two kinds of OLED display devices. One is that the light emitting layer can emit light of three primary colors such as red light, green light and blue light. The other is that the light-emitting layer emits white light. In the case of the light-emitting layer emitting white light, in order to realize color display, the OLED display device also includes a ...
