Organic electroluminescent display panel with auxiliary electrodes, method for manufacturing the same, and display device using the same

#The present disclosure relates to a field of display technology.

#An organic light-emitting diode (OLED) display panel, having advantages of small thickness, self-illumination, low power consumption, good flexibility, and so on, has been regarded as a most potential display panel for a display device. People have more and more demands on the size of the active area and the thickness of the OLED display panel for achieving better visual and touch experiences.

#In view of this, there is a need to provide an organic electroluminescent display panel, a method for manufacturing the same, and a display device using the same against the problem that the bending or subjecting of the drop impact of the display panel may induce the display defects.

#Implementations are described by way of example only with reference to the attached figures.

#FIG. 1 is a schematic plane view of a pixel region of an organic electroluminescent display panel according to an embodiment of the present disclosure.

#FIG. 2 is a schematic sectional view of a sub-pixel region of the organic electroluminescent display panel according to an embodiment of the present disclosure.

#In conventional techniques, a larger active area and a smaller thickness are generally accompanied with a lower strength of the OLED display panel. Especially if the flexible OLED display panel is repeatedly bent/folded or is subjected to a drop impact, a stress would tend to be concentrated rather than dissipated, which may easily cause a damage to elements such as an anode, an organic light-emitting unit, or a cathode, consequently, a full color display may unable to be achieved at the bent area or the impacted area, and a display defect phenomenon, such as blackspot, bright spot, or color spot, may occur.

#The present disclosure will be described in details in combination with the accompanying drawings for better understanding. The accompanying drawings show preferred embodiments of the present disclosure. However, the present disclosure may be implemented in a plurality of forms or ways, and are not limited to the embodiments described herein. On the contrary, the embodiments described herein are intended to make the disclosure of the present disclosure more clearly and thoroughly understood.

#In addition, in the present disclosure, the term “schematic plane view” refers to a schematic view of an object observed from its top. The term “schematic sectional view” refers to a schematic view of an object observed from its side after vertically cutting off a portion of the object from its top so as to expose a section of the object.
