Embodiment 1

[0029] This embodiment provides an organic light emitting display device, such as image 3 As shown, it includes a transparent substrate 1 divided into a display area 2 and a non-display area, and one or more organic light emitting diodes are arranged on the display area 2.

[0030] Such as figure 2 As shown, the organic light emitting diode includes a first electrode 21, an organic layer 22, and a second electrode 23 stacked in sequence. The first electrode 21 is disposed close to the substrate 1, and the first electrode 21 is transparent or semi-transparent. The transparent electrode allows the light emitted from the display area 2 to be emitted through the first electrode 21 of the organic light emitting diode and the substrate 1.

[0031] As in the prior art, the organic layer 22 includes a light-emitting layer, and a combination of one or more layers of a hole injection layer, a hole transport layer, an electron blocking layer, a hole blocking layer, an electron transport laye...

Embodiment 2

[0041] This embodiment provides an organic light emitting display device, such as Figure 4 As shown, the structure and manufacturing method of the organic light-emitting display device are the same as those of Embodiment 1, except that the light shielding layer 4 is disposed between the first electrode 21 and the organic layer 22. When the light emitted from the display area 2 is refracted by the substrate 1, the refracted light is absorbed by the light shielding layer 4, and no ghosting phenomenon can occur, thereby improving the clarity of the display area and improving the display quality.

Abstract

The invention provides an organic luminous display device. A shading layer which surrounds a display region is arranged in a non-display region and is provided with an emergent opening; the area of the opening is equal to that of the display region; The shading layer is arranged at the outer side of a base plate; light rays emitted from the display region are ejected from the emergent opening; due to the restriction of the shading layer, the light rays emitted from the display region can not be subjected to a refraction phenomenon, so that the occurrence of a ghost phenomenon is effectively prevented; the shading layer is also can be arranged between the base plate and the organic light-emitting diode or between layers in the organic light-emitting diode; when the light rays emitted from the display region are refracted by virtue of the base plate, refractive light rays are absorbed by the shading layer, so that the ghost phenomenon can not be generated, therefore the definition of the display region is improved, and the display quality is improved.

Description

Technical field [0001] The invention relates to the field of organic electroluminescence, in particular to an organic light emitting display device for preventing ghosting. Background technique [0002] According to the size division, the display device whose diagonal size of the display panel is between 0.7 and 3 inches is usually called a micro-display device. Micro display devices have the characteristics of small size, low power consumption, high resolution, etc., which make their applications in portable display devices have great advantages. [0003] Organic Light-Emitting Device (Organic Light-Emitting Device in English, OLED for short) is an active light-emitting device that has the advantages of low power consumption, all-solid-state display, thinner volume, etc., and has broad development prospects in the field of microdisplay. [0004] The micro display device has high resolution and has extremely high requirements on the optical performance of the display device. But in...
