Problems solved by technology

However, for OLED panels with COE structure, as the light output angle increases, the color purity of red and blue light does not change significantly, while the color purity of green light changes greatly, which eventually leads to the optical performance of OLED panels with COE structure. Not ideal, affecting its display effect

Embodiment 1

[0047] This embodiment provides an organic electroluminescent display panel, such as Figure 4 As shown, it includes a green light-emitting element 1 and a green color filter layer 2 correspondingly arranged on the light-emitting side of the green light-emitting element 1, and the traveling distance L of the light emitted by the green light-emitting element 1 in the green color filter layer 2 changes with its light-emitting angle θ constant.

[0048] Among them, the green light emitting element 1 can be regarded as a point light source. The light output angle θ refers to the angle between the propagation direction of the light emitted by the light emitting source and the direction perpendicular to the surface of the display panel.

[0049] Since the light (green light) emitted by the green light-emitting element 1 changes with its light-emitting angle, its color purity does not change significantly, but the light emitted by the green light-emitting element 1 passes through th...

Embodiment 2

[0076] This embodiment provides a display device, including the organic electroluminescence display panel in Embodiment 1.

[0077] By using the organic electroluminescence display panel in Example 1, the display effect and display quality of the display device are improved.

[0078] The display device provided by the present invention can be any product or component with a display function such as an OLED panel, an OLED TV, a monitor, a mobile phone, a navigator, and the like.

Abstract

The invention provides an organic electroluminescence display panel, a preparation method of the same, and a display device. The organic electroluminescence display panel includes a green light-emitting component and a green color film layer which is correspondingly arranged at the light extraction side of the green light-emitting component, wherein the walking distance of the light emitted from the green light-emitting component in the green color film layer does not change following change of the light extraction angle. As the organic electroluminescence display panel enables the walking distance of the light emitted from the green light-emitting component in the green color film layer to be unchanged following change of the light extraction angle, the organic electroluminescence displaypanel can prevent changing of the color purity of the green light passing the green color film layer so as to improve the color cast performance of the green light passing the green color film layerand improve the optical expression of the green light, so that the display effect of the organic electroluminescence display panel can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic electroluminescence display panel, a preparation method thereof, and a display device. Background technique [0002] At present, organic electroluminescent (OLED) display products have a higher and higher share in small and medium-sized products. The most important advantage of OLED display products in the future is that they can be bent, so the thickness of OLED display panels needs to be continuously reduced. However, in order to reduce the reflectivity of OLED display panels, circular polarizers need to be attached, so the overall thickness of OLED display panels cannot Support random bending. [0003] COE (CF on EL) technology is to form a color-resisting layer (ie CF, color film layer) on a thin-film-encapsulated organic electroluminescent (EL) device. This structure has the functions of reducing the reflectivity of the OLED panel and improving its color...
