Display panel and method of manufacturing same

#The present disclosure relates to the field of electronic display technologies, and more particularly to a display panel and a method of manufacturing the same.

#Organic light emitting diode (OLED) display panels have high contrast ratio, wide viewing angle, and fast response speed, and are expected to replace liquid crystal display panels as s mainstream choice for next-generation displays.

#At present, large-size OLED display panels adopt a 3T1C driving circuit, and its aperture ratio is approximately between 20% and 30%. In a conventional bottom emitting display panel, light emitted from an organic layer needs to be emitted through each film layer of a driving circuit. Since metal in a capacitor area is opaque, light cannot penetrate. Therefore, an open area of a 3T1C pixel driving circuit and the storage capacitor are usually designed separately, as shown in FIG. 1, thereby reducing an aperture ratio of a pixel. In addition, since pixel patterns in pixel points are concentrated in a small space, it is easy to cause short circuit, open circuit, and other electrical defects, which reduces the product yield.

#In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings used in the description of the embodiments will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the present application. Other drawings can also be obtained from those skilled in the art based on these drawings without paying any creative effort.

#FIG. 1 is a schematic structural view of a driving circuit of an organic light emitting diode (OLED) display panel in the prior art.

#FIG. 2 is a schematic structural view of a driving circuit of an OLED display panel according to an embodiment of the present application.

#The following description of the various embodiments is provided to illustrate the specific embodiments of the present invention. The directional terms mentioned in the present application, such as up, down, front, back, left, right, inside, outside, side, etc., are only directions referring to the additional drawings. Therefore, the directional terminology used is for the purpose of illustration and understanding and is not intended to be limiting. In the figures, structurally similar elements are denoted by the same reference numerals.

#Referring to FIG. 1, the prior art is briefly described first. A 3T1C pixel driving circuit in the prior art includes a functional area 010 and a light transmitting area 020. A gate line 012, a data line 011, and a storage capacitor 013 are distributed in different film layers of the functional area 010 and are isolated from each other by an insulating layer.

#For a bottom light emitting display panel, since metal of a capacitor area is opaque, light cannot penetrate. Therefore, an open area of a 3T1C pixel driving circuit and the storage capacitor are usually designed separately, thereby reducing an aperture ratio of a pixel. In addition, since pixel patterns in pixel points are concentrated in a small space, it is easy to cause short circuit, open circuit, and other electrical defects, which reduces the product yield.
