Flexible display device and manufacturing method thereof

Abstract

The invention provides a flexible display device which comprises a flexible substrate, organic luminescent devices arranged on the two sides of the flexible substrate and an external circuit. Each organic luminescent device comprises a first electrode layer, a luminescent layer and a second electrode layer, and a third electrode layer and a fourth electrode layer are arranged at the two ends of the external circuit respectively. Conducting particles are included in the flexible substrate, and when pressure is applied, the distances among the conducting particles are reduced, and electric conduction in the vertical direction is achieved. Meanwhile, electrode connecting layers running through the flexible substrate are formed through heating solidification. The first electrode layer and the third electrode layer are in electric conduction through the corresponding electrode connecting layer, and the second electrode layer and the fourth electrode layer are in electrode conduction through the corresponding electrode connecting layer. The flexible substrate including the conducting particles is adopted in the flexible display device, and thus electrodes on the two sides of the substrate can be in reliable electric connection through the conducting particles in the flexible substrate.

Description

technical field [0001] The invention relates to the field of organic optoelectronics, in particular to a flexible display device and a preparation method thereof. Background technique [0002] With the continuous development of display technology, OLED (Organic Light Emitting Diode) has increasingly become an international research hotspot due to its advantages of high luminance, rich colors, low-voltage DC drive, and simple preparation process. OLED has a wider field of view and can be made into larger-sized products to meet users' requirements for different sizes. The above-mentioned outstanding advantages determine that OLED will become the mainstream of next-generation display technology. On the other hand, due to its many advantages such as thin thickness, light weight, bendability and even rollability, flexible display must be one of the trends of display technology, and the future market prospect is broad. How to integrate OLED and flexible display has become the ma...
