Problems solved by technology

When the separators are integrated instead of separated from each other, the cathode electrode on the separator is sometimes short-circuited due to the step difference between the separators, so that the OLED will have defects

Embodiment Construction

[0014] Certain embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals generally refer to like elements throughout.

[0015] figure 1 is a block diagram showing an organic light emitting display (OLED).

[0016] Such as figure 1 As shown, the OLED 1000 includes a scan driver 100 , a data driver 200 and an OLED panel (hereinafter, referred to as a panel) 300 .

[0017] The scan driver 100 sequentially supplies scan signals to the panel 300 through the scan lines ScanRGB[1], ScanRGB[2], . . . , ScanRGB[n].

[0018] The data driver 200 supplies data signals to the panel 300 through data lines DataRGB[1], DataRGB[2], . . . , DataRGB[m].

[0019] In addition, the panel 300 includes a plurality of scanning lines ScanRGB[1], ScanRGB[2], ..., ScanRGB[n] arranged along the row direction, and a plurality of data lines DataRGB[1], DataRGB[2] arranged along the column direction. ],..., DataRGB[m] and ...

Abstract

Disclosed is an OLED in which separation regions of spacers in odd and even rows are formed so that a fine metal mask (FMM) between light emission layers may move without being caught in the spacers. The OLED includes even and odd spacers protruding upwardly between light emission layers and are separated by separation regions. The separation regions of each row of spacers are aligned with spacers of adjacent rows and are not aligned with the separation regions of the adjacent rows.

Description

technical field [0001] The field relates to an organic light emitting display (OLED), and more particularly, to an OLED in which the separation area of ​​the odd spacers is different from that of the even spacers so that the mask can be moved and the mask The mold is not caught in the partition, and the resistance against external shock is increased, thereby effectively protecting the display area. Background technique [0002] An organic light emitting display (OLED) is a display device that emits light by electrically exciting phosphor or phosphor organic compounds. The OLED drives N×M organic light emitting diodes to display images. In some embodiments, an OLED includes an anode (ITO), a thin organic layer, and a cathode (metal). The organic thin layer generally has a multilayer structure including an emission layer (EML), an electron transport layer (ETL), and a hole transport layer (HTL) to improve the balance between electrons and holes, thereby increasing emission e...
