Problems solved by technology

In the case where the shielding touch lines are unevenly located in various regions of the organic light emitting array, the visibility of the touch lines in the various regions of the organic light emitting array is different from each other, which reduces the visual experience experienced by the user.
[0009] The problem of visibility becomes more serious when the angle at which the user views the OLED changes

[0079] Figure 3A is a plan view showing one pixel of the organic light emitting array of the organic light emitting display device according to the first embodiment, Figure 3B is shown with Figure 3A a plan view of an area of ​​the corresponding touch panel, and Figure 3C It is a plan view showing a state in which a touch panel and an organic light emitting array of an organic light emitting display device are laminated. Figure 4A with 4B are respectively along Figure 3C Cross-sectional views taken on lines II' and II-II'.

[0080] Such as Figure 3A As shown, the organic light emitting array is arranged such that a plurality of pixel regions P are arranged in a matrix on the second substrate 200 . Each pixel area P includes at least three sub-pixels SP1, SP2 and SP3. The subpixels SP1, SP2, and SP3 in each pixel region P may emit different colors, or two or more subpixels in each pixel region P may emit the same color. For example, in case each pixel area includ...

Abstract

An organic light-emitting display device is disclosed. The organic light-emitting display device includes an organic light-emitting array including a plurality of pixel areas, each of which comprisesat least three sub-pixels, the pixel areas being arranged in a matrix fashion, and a touch electrode array divided into a plurality of blocks, in each of which a plurality of touch wires is arranged in a first direction and a second direction. Each of the sub-pixels has a light-emitting part, the light-emitting part of one of the sub-pixels is larger than the light-emitting parts of the other sub-pixels, and an intersection of the touch wires arranged in the first direction and the second direction is located in the sub-pixel having the largest light-emitting part.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2016-0127058 filed on September 30, 2016, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a display device, and more particularly, to an organic light emitting display device capable of preventing touch lines from being visible in a structure in which a touch panel is integrated into the organic light emitting display device, and also in a structure in which a non-light emitting portion is narrow. Can solve the problem of color viewing angle. Background technique [0003] Examples of display devices include liquid crystal display (LCD) devices, organic light emitting display devices, plasma display panel (PDP) devices, quantum dot display devices, field emission display (FED) devices, and electrophoretic display (EPD) devices. Each of these devices includes a flat display panel for displaying images. A flat display panel ...
