Embodiment 1

[0031] Such as Figure 4 Shown is a schematic cross-sectional view of an embodiment of an organic light-emitting display device with a series-parallel structure in the present invention. A glass substrate 411 is provided with a plurality of light-emitting units spaced apart from each other. Two adjacent light-emitting units 41 in the same row are composed of The first electrode 412, the light emitting layer 413 and the second electrode 414 are composed of the first electrode 422, the light emitting layer 423 and the second electrode 424, and the first electrodes 412 and 422 of the light emitting units 41 and 42 are separated from each other. Yes, an auxiliary electrode 415, a light emitting layer 413 and a second electrode 414 are sequentially arranged on the first electrode 412 of the light emitting unit 41, wherein the light emitting layer 423 of the adjacent light emitting unit 42 is on the first electrode 422 and ends at two In the interval between the first electrodes 412...

Embodiment 2

[0036] Such as Figure 6 Shown is a schematic cross-sectional view of another embodiment of the organic light-emitting display device having a series-parallel structure according to the present invention. The difference from Embodiment 1 is that this embodiment adopts a spacer structure. The glass substrate 611 is provided with a plurality of separated light-emitting units. In two adjacent light-emitting units in the same row, the light-emitting unit 61 is composed of a first electrode 612, a light-emitting layer 613 and a second electrode 614. The light-emitting unit 62 is composed of a second electrode 612. An electrode 622, a light-emitting layer 623 and a second electrode 624, the first electrodes 612, 622 of the two light-emitting units 61, 62 are separated from each other, and the first electrode 612 of the light-emitting unit 61 is sequentially provided with auxiliary electrode 615, light-emitting layer 613 and second electrode 614, and an isolation column 616 is also p...

Embodiment 3

[0041] The difference from the above two embodiments is that in this embodiment, an auxiliary electrode is also provided in the interval between any two adjacent light-emitting units in each row of light-emitting units in the display area of ​​the organic light-emitting display device, such as Figure 7 As shown, it is a schematic diagram of the connection of the auxiliary electrodes of another embodiment of the present invention. It can be seen from the figure that, except that a strip-shaped auxiliary electrode is provided in the interval between any two adjacent rows of light-emitting units, each row emits light. A strip-shaped auxiliary electrode 74 is also provided between any two adjacent light-emitting units 711 and 721 and between 721 and 731 of the unit, so that each light-emitting unit 722 is surrounded by auxiliary electrodes, so that not only each The light-emitting units on the row are electrically connected, and the light-emitting units on each column are also ele...

Abstract

The invention relates to an organic light-emitting display device comprising a first electrode, a second electrode and a light-emitting layer, comprising a plurality of light-emitting units arranged in rows and columns on a substrate, characterized in that the light-emitting units of each adjacent column Auxiliary electrodes are provided in the intervals to realize electrical connection between the light emitting units, wherein the light emitting units in each row are connected in series, and the light emitting units in each column are connected in parallel, and the auxiliary electrodes are formed on the first electrodes, It is a continuous strip shape in the column direction. The organic light-emitting display device with a series-parallel structure of the present invention well solves the defect that the light-emitting device cannot emit light uniformly when a short circuit occurs in the prior art, improves the light-emitting performance, and simplifies the preparation process.

Description

technical field [0001] The invention relates to the field of organic light-emitting displays, in particular to an organic light-emitting display device that can reduce damage caused by short-circuit defects and improve display uniformity. Background technique [0002] One of the problems currently faced in the manufacture of large-area organic light-emitting display devices is the failure caused by short-circuit defects. A single short circuit defect will cause damage to the entire organic light emitting display device, making it no longer emit light. [0003] In order to solve the above defects, Chinese patent application (application number: 03127477.3, publication date: March 24, 2004) discloses an OLED device with a series connection structure of light emitting devices, in which, through the bottom of adjacent light emitting devices The electrode is in contact with the top electrode to form an electrical connection, thereby realizing a series-connected OLED device. The ...
