Abstract

The invention provides a flexible organic light emitting diode display and a preparation method thereof, which are used to realize the absorption of the stress generated in the bending process of the flexible organic light emitting diode display, and prevent the electrodes of the flexible organic light emitting diode display from being broken due to stress, affecting the Display quality. A flexible organic light emitting diode display provided by the present invention includes a first flexible substrate and a second flexible substrate opposite to it, wherein a thin film transistor, a first passivation layer, a first electrode, an organic The light-emitting layer, the second electrode, and the cathode, anode, thin film transistor TFT and the second flexible substrate respectively located under the first flexible substrate, are characterized in that a stress absorbing layer is also included between the second electrode and the second flexible substrate , the material of the stress absorbing layer is a resin material.

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 carrying. [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, an organic light emitting layer (EL) 008 , Cathode 009, second passivation layer 012, adhesive 010 and second flexib...
