Abstract: When using a flexible substrate to protect and support various components of an organic light emitting display device, among components including driving elements disposed on each of pixels of the organic light emitting display device, components where a high-level signal is applied during an emission period are grouped and are disposed on one side of the pixels. Further, components where a low-level signal is applied during the emission period are grouped and are disposed on the other side of the pixels. Accordingly, an electric field occurring due to a potential difference in the flexible substrate is minimized and shifting of a threshold voltage Vth of a thin-film transistor may be minimized. Thus, an OLED without an after-image can be provided.

Abstract: An electroluminescent display device is provided. The device includes a substrate on which a display area displaying an image and a non-display area surrounding the display area are defined. The device includes a thin film transistor and a light-emitting diode disposed in the display area on the substrate and electrically connected to each other. The device further includes an encapsulation part covering the thin film transistor and the light-emitting diode, a touch sensor part on the encapsulation part, and first and second crack stoppers disposed in the non-display area on the substrate. The second crack stopper is disposed between the first crack stopper and the display area. The first crack stopper includes a first pattern that is formed through a same process as an electrode layer of the touch sensor part.

Abstract translation: 当使用柔性基板来保护和支持有机发光显示装置的各种部件时，在包括设置在有机发光显示装置的每个像素上的驱动元件的部件中，在发光期间施加高电平信号的部件 被分组并且被布置在像素的一侧上。 此外，在发射周期期间施加低电平信号的部件被分组并且被布置在像素的另一侧上。 因此，由于柔性基板上的电位差而产生的电场被最小化，薄膜晶体管的阈值电压Vth的偏移可能被最小化。 因此，可以提供没有后置图像的OLED。
