Abstract

The invention provides a flexible organic light-emitting diode display and a method for manufacturing the same. The flexible organic light-emitting diode display comprises a first flexible substrate and a second flexible substrate opposite to the first flexible substrate. A thin film transistor, a first passivation layer, a first electrode, an organic light-emitting layer and a second electrode are sequentially manufactured on the first flexible substrate, and the cathode, the anode, the thin film transistor (TFT) and the second flexible substrate are sequentially positioned on the first flexible substrate. The flexible organic light-emitting diode display is characterized in that a stress absorbing layer is further arranged between the second electrode and the second flexible substrate and is made of resin materials. The flexible organic light-emitting diode display and the method have the advantage that stress generated by the flexible organic light-emitting diode display in a bending procedure can be absorbed, so that breakage of the electrodes of the flexible organic light-emitting diode display and the influence on the display quality due to the effect of the stress can be prevented.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible organic light emitting diode display and a preparation method thereof. Background technique [0002] Flexible displays have many advantages, such as impact resistance, strong shock resistance, light weight, small size, and more convenient to carry. [0003] At present, the main flexible displays can be roughly divided into three types: electronic paper (or flexible electrophoretic display), flexible organic light emitting diode (Organic Light Emitting Diode, OLED) and flexible liquid crystal. [0004] see figure 1 It can be seen that the flexible organic light emitting diode display in the prior art includes from bottom to top: a first flexible substrate 001, a thin film transistor TFT003, a first passivation layer 005, an anode 006, a pixel defining layer 007, and an organic light emitting layer (EL) 008 , a cathode 009, a second passivation layer 012, an adhesive ...
