Embodiment 1

[0027] Such as figure 1 As shown, this embodiment relates to a display device, specifically, the display device includes: a substrate 100 and N-layer organic light emitting devices 101 stacked in sequence on the substrate 100 (that is, all the organic light emitting devices 101 are vertically overlapped), and each layer of organic light emitting devices 101 in the N layers of organic light emitting devices 101 includes a light-transmitting region (the light-transmitting region is not provided with pixels at all) and a display region. In an embodiment of the present invention, each layer of organic light-emitting The light-emitting device 101 includes only one organic light-emitting device; wherein, the display area of ​​the organic light-emitting device 101 in the Mth layer (the organic light-emitting device 101 in any layer except the organic light-emitting device 101 located on the uppermost layer) is the same as the organic light-emitting device in the N-th layer. At least ...

Embodiment 2

[0044] Such as Figure 5 As shown, this embodiment is roughly the same as Embodiment 1, and the display device includes a substrate 200, an N-layer organic light emitting device, and a cover glass 203; the only difference is that each layer of organic light emitting devices in this embodiment includes two organic light emitting devices Devices 201, 202; of course, each layer of organic light emitting devices may include two organic light emitting devices 201, 202 as shown in the figure, or may include three or more organic light emitting devices, as long as the organic light emitting device of the Mth layer The display area (an organic light-emitting device in any layer other than the organic light-emitting device located in the uppermost layer) and at least part of the light-transmitting area of ​​the organic light-emitting device in the Nth layer (the organic light-emitting device located in the uppermost layer) overlap each other, and each layer The pictures displayed in th...

Embodiment 3

[0046] Such as Image 6 As shown, this embodiment relates to a method for manufacturing a display device. Specifically, the method includes:

[0047] In step S1, a substrate is provided, which may be a flexible or rigid substrate, wherein the flexible manufacturing process is more difficult than the rigid one, but this does not affect the purpose of the present invention.

[0048] Step S2, preparing N-layer organic light-emitting devices on the substrate; wherein, each N-layer organic light-emitting device includes a light-transmitting area and a display area, and the display area of ​​the M-layer organic light-emitting device is at least the same as the N-layer organic light-emitting device. Part of the light-transmitting regions overlap each other, and N and M are both natural numbers, and M

[0049] In a preferred embodiment of the present invention, the steps of preparing each layer of the organic light-emitting device include:

[0050] forming a driving element, opti...

Abstract

The present invention relates to the field of display technology, in particular to a display device and a manufacturing method thereof. N-layer organic light-emitting devices are arranged on a substrate, and each N-layer organic light-emitting device includes a light-transmitting region and a display region; wherein, the first The display area of ​​the M-layer organic light-emitting device overlaps with at least part of the light-transmitting area of ​​the N-th layer organic light-emitting device (N and M are both natural numbers, and M<N), and the pictures displayed in the display areas of each organic light-emitting device are spliced ​​into a A complete picture, and the display device controls the pixel units in each display area to display alternately through independent driving elements, so as to achieve the effect of naked-eye 3D.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a preparation method thereof. Background technique [0002] 3D, D is the abbreviation of English Dimension (yuan, dimension), and 3D refers to three-dimensional space. We know that in daily life, people mostly use two eyes to observe the surrounding external scenes with a three-dimensional sense of space. 3D display technology uses the principle of binocular stereo vision to enable people to obtain a sense of three-dimensional space. The current 3D display technologies include naked-eye and There are two types of glasses-type; the so-called naked-eye 3D is to send encoded 3D video images to the left and right eyes independently through special processing on the display panel, so that users can experience the stereoscopic feeling with naked eyes without the help of stereoscopic glasses. At the same time, it can be compatible with 2D images. Glasses-free 3D i...
