OLED display panel, manufacturing method of OLED display panel and display device

Abstract

The invention discloses an OLED display panel, a manufacturing method of the OLED display panel and a display device. The OLED display panel comprises an array substrate and a packaging cover plate oppositely arranged and further comprises an OLED layer formed on the face, facing the packaging cover plate, of the array substrate, and the OLED layer comprises a plurality of OLEDs. The OLED display panel further comprises at least one thin film packaging layer, a color filtering layer and pasting glue, wherein the thin film packaging layer covers the OLED layer and is bonded with the array substrate, the color filtering layer is formed on the face, facing the packaging cover plate, of the thin film packaging layer, the portion between the array substrate and the packaging cover plate is filled with the pasting glue so that the array substrate and the packaging cover plate can be pasted, and the pasting glue covers the color filtering layer and the thin film packaging layer. According to the OLED display panel, the distance between the OLED layer and the color filtering layer is small, and the large view angle color cast problem of the OLED display panel can be relieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel, a preparation method thereof, and a display device. Background technique [0002] With the vigorous development of flat-panel display devices, compared with traditional liquid crystal display panels, Organic Light Emitting Diode (OLED) display panels have the advantages of fast response, wide color gamut, ultra-thin, self-illumination, and flexibility. and other features, has gradually become the mainstream of the new generation of flat panel display devices. [0003] In the prior art, in order to realize the full color of the OLED display panel, it is generally realized by stacking a top-emitting white organic light emitting diode (White Organic Light Emitting Diode, WOLED) and a color filter layer (Color Filter, CF). Among them, the superposition process of the WOLED layer and the color filter layer with multiple WOLEDs can achieve high resolution of th...

Problems solved by technology

[0004] However, in the prior art, in the OLED display panel in which the top emission WOLED layer 01 and the color filter layer 03 are stacked, after the packaging cover plate 04 and the array substrate 02 are connected to each other, the gap between the color filter layer 03 and the WOLED layer 01 A thicker layer of transparent adhesive material 05 makes the distance between the color filter layer 03 and the WOLED layer 01 larger, and because the WOLED layer 01 has the characteristics of a self-luminous light source, the WOLED layer 01 and a sub-section of the display panel In the process of laterally reaching the color filter layer 03, the light emitted by the corresponding area of ​​the pixel unit will pass through the transparent adhesive material 05 and shoot to the color filter layer of other sub-pixel units, thereby causing color mixing of the product and making the OLED display panel There is a problem of large viewing angle deviation, which affects the display effect of the OLED display panel
