Embodiment Construction

[0032] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0033] Figure 1a-Figure 1b It is a schematic diagram of changes in viewing angle when a viewer watches a large-screen display panel in the prior art; Figure 1a Flat screen shown, Figure 1b Curved screen shown. When the viewing angle of the viewer changes from the zero viewing angle center of the large-screen display panel to the edge position where the viewing angle gradually increases, the wavelength observed by the observer will shift in light, causing the viewer to see the color of the center position and edge position of the display panel Inconsistencies seriously affect the viewing experience. Based on this problem, an embodiment of the present invention provides an OLED display panel, which can effectively suppress the phenomenon of blue shift...

Abstract

Embodiments of the present invention provide an OLED display panel, a display device, and a method for manufacturing an OLED display panel, wherein the display panel includes: an encapsulation layer; and encapsulation layers on pixel units in the direction from the center position of the display panel to the edge position of the display panel The layer thickness shows an increasing trend. In the embodiment of the present invention, from the center position of the display panel to the edge position of the display panel, the thickness of the encapsulation layer on the pixel unit tends to increase, increasing the resonant cavity length of the pixel unit at the edge position of the display panel, so that the organic The wavelength of the peak of the light emitting spectrum of the light emitting diode increases gradually, thereby suppressing the blue shift of the position of the light emitting peak of pixels at the edge of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel, a display device and a method for manufacturing the OLED display panel. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display device has self-illumination, no backlight module, high contrast and definition, wide viewing angle, full curing, suitable for flexible panels, good temperature characteristics, low power consumption, A series of excellent characteristics such as fast response speed and low manufacturing cost have become one of the key development directions of a new generation of flat panel display devices, and thus attract more and more attention. [0003] At present, OLED has been applied to mobile phones and has been popularized rapidly. TVs using OLED have gradually begun to sell well. However, the defect in display technology of TVs using OLED is that when the viewing angle of the viewer change...
