Flexible OLED display panel having a substrate with a titanium layer and method for manufacturing same

A flexible organic light-emitting diode (OLED) display panel including a flexible substrate and a plurality of thin film transistor (TFT) devices disposed on the flexible substrate, the flexible substrate comprising:

• a first polyimide (PI) layer;
• a first inorganic barrier layer disposed on a surface of the first PI layer;
• a titanium metal layer disposed on a surface of the first inorganic barrier layer, wherein the titanium metal layer is patterned;
• a second PI layer directly disposed on a surface of the titanium metal layer;
• and
• a second inorganic barrier layer disposed on a surface of the second PI layer;
• wherein the TFT devices are disposed on a surface of the second inorganic barrier layer.

A method for manufacturing a flexible organic light-emitting diode (OLED) display panel, comprising:

• a step S10 of providing a glass base plate;
• a step S20 of forming a first polyimide (PI) layer on the glass base plate;
• a step S30 of forming a first inorganic barrier layer on the surface of the first PI layer;
• a step S40 of forming a titanium metal layer on a surface of the first inorganic barrier layer;
• a step S50 of forming a second PI layer directly on a surface of the titanium metal layer;
• a step S60 of forming a second inorganic barrier layer on a surface on the second PI layer;
• and
• a step S70 of forming a plurality of thin film transistor (TFT) devices on a surface of the second inorganic barrier layer;
• wherein the step S40 further comprises:
• a step S401 of patterning the titanium metal layer to form a pattern on the titanium metal layer.
