Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] see figure 1 with 2 The device structure of the flexible transparent OLED includes: a flexible transparent substrate 1 with a rectangular sawtooth structure on one side. A plurality of first transparent electrodes 2 are provided, and a plurality of reflective electrodes 3 are provided in several grooves of a rectangular sawtooth structure; and the first transparent electrodes 2 and the reflective electrodes 3 are covered by an organic layer 4, and the organic layer 4 The second transparent electrode 5 and the encapsulation layer 6 are sequentially arranged on the top, the encapsulation layer 6 is a thin film encapsulation layer, and is encapsulated in a manner of alternately stacking organic and inorganic barrier films. Both the reflective electrode 3 and the first transparent electrode 2 have a width of 1-3mm. The relative height of the first trans...

Abstract

The invention belongs to the field of OLEDs, and specifically relates to a device structure and a preparation method of a flexible transparent OLED; the device structure includes a flexible transparent substrate with a rectangular sawtooth structure on one side, and a first The transparent electrode is provided with a reflective electrode in the groove; and both the first transparent electrode and the reflective electrode are covered by an organic layer, and the second transparent electrode and the encapsulation layer are sequentially arranged on the organic layer. By arranging a reflective electrode on one side of the first transparent electrode, the internal light can only be emitted outward from the second transparent electrode, and the light emitting direction of the transparent OLED can be controlled to realize unilateral light emission.

Description

technical field [0001] The invention belongs to the field of OLEDs, and in particular relates to a device structure and a preparation method of a flexible transparent OLED. Background technique [0002] With the vigorous development of display technology, transparent display has begun to enter the public's field of vision. However, today's transparent display devices all emit light on both sides, and the direction of light emission of the panel cannot be controlled. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings in the prior art, and provide a device structure and preparation method of a flexible transparent OLED, which has the advantage of being able to control the light emitting direction of the panel. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: including: a flexible transparent substrate with a rectangular sawtooth structure on one ...
