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

The embodiment of the invention provides an OLED display panel, a display device and a manufacturing method of the OLED display panel. The display panel includes an encapsulation layer, the thicknessof the encapsulation layer on the pixel unit increases from the center position of the display panel to the edge position of the display panel. In accordance with an embodiment of the present invention, in a direction from a center position of the display panel to an edge position of the display panel, The thickness of the encapsulation layer on the pixel unit increases gradually, which increasesthe resonant cavity length of the pixel unit of the display panel in the edge position, and increases the wavelength of the light emission spectrum peak of the organic light emitting diode gradually,thereby suppressing the phenomenon of blue shift of the light emission peak position of the pixel of 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...
