Problems solved by technology

However, the inventors have found that when the transparent OLED display device is normally displayed, because the OLED display substrate and the OLED device have a higher light transmittance, the ambient light from the back side (non-display surface) of the transparent OLED display device is easily Through the display substrate, these ambient lights and the light emitted by the OLED display device enter the human eye together, which will have a certain impact on the normal display effect of the OLED display device.

Embodiment 1

[0034] This embodiment provides an OLED display substrate, where most of the whole area of ​​the OLED display substrate is a transparent area (specifically, the area of ​​the OLED device 2 is a transparent area, and the area of ​​the thin film transistor is a non-transparent area).

[0035] Such as figure 1 As shown, the OLED display substrate provided in this embodiment includes the following structure: a substrate 1 , and a plurality of OLED devices 2 and light selection patterns 3 disposed on the substrate 1 . in,

[0036] The substrate 1 is a transparent substrate 1, and its material may include materials such as polyimide, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, and polyethersulfone.

[0037] The OLED device 2 includes: a transparent first electrode 21 , a light emitting layer 22 , and a transparent second electrode 23 sequentially disposed on the substrate 1 along a direction away from the substrate 1 . Wherein, the light emitting layer 22 ...

Embodiment 2

[0052] This embodiment provides a method for preparing an OLED display substrate, which can be used to prepare any OLED display substrate provided in Embodiment 1. The preparation method includes:

[0053] A step of forming a plurality of light selection patterns and a plurality of OLED devices on a substrate; wherein the OLED device includes: a transparent first electrode, a light-emitting layer, and a transparent second electrode; the light selection patterns are arranged on the non-display surface side of the OLED device , and one-to-one correspondence with the OLED devices; the wavelength range of the light allowed to pass by each light selection pattern is the same as the wavelength range of the light emitted by the corresponding OLED device.

[0054] And, in the step of forming the transflective structure on the side of the light selection pattern away from the OLED device, the reflectivity of the transflective structure to the light incident from the side close to the l...

Embodiment 3

Abstract

The invention provides an OLED display substrate, a preparation method of the OLED display substrate, and a display device, which belong to the field of display technology and can solve the problem that the transparent OLED display substrate in the prior art is greatly affected by external ambient light and has poor display effect. The OLED display substrate of the present invention has a display surface and a non-display surface opposite to the display surface; the OLED display substrate includes: a base; a plurality of OLED devices arranged on the base; the OLED device includes: transparent a first electrode, a light-emitting layer, and a transparent second electrode; a plurality of light selection patterns, the light selection patterns correspond to the OLED device one by one, and are arranged on the side of the OLED device close to the non-display surface; The wavelength band range of the light allowed to pass by each of the light selection patterns is the same as the wavelength band range of the light emitted by the corresponding OLED device.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an OLED display substrate, a preparation method of the OLED display substrate, and a display device. Background technique [0002] In the prior art, a transparent OLED display device that emits light from one side requires that the OLED display substrate be a transparent substrate to ensure that the OLED display device as a whole has a higher light transmittance. However, the inventors have found that when the transparent OLED display device is normally displayed, because the OLED display substrate and the OLED device have a higher light transmittance, the ambient light from the back side (non-display surface) of the transparent OLED display device is easily Through the display substrate, the ambient light and the light emitted by the OLED display device enter human eyes together, which will affect the normal display effect of the OLED display device to a certain ext...
