Title: ACTIVE-MATRIX ORGANIC LIGHT-EMITTING DIODE DISPLAY SCREEN AND PACKAGING METHOD THEREOF, AND TERMINAL DEVICE
Abstract:
Provided are an active-matrix organic light-emitting diode (AMOLED) display screen and a packaging method thereof, and a terminal device. The display screen comprises: an array substrate (10); a package substrate (20); and metal plates (60). The metal plates are located between the array substrate and the package substrate. At least one metal atom located at a first surface of the metal plate and at least one atom located at a packaging region (B) of the package substrate are bonded with the same ligand. Alternatively, the least one metal atom located at the first surface of the metal plate and at least one atom located at a packaging region (A) of the array substrate are bonded with the same ligand. The AMOLED display screen uses the metal plates positioned in the packaging regions to seal an organic light-emitting material therein, such that the organic light-emitting material is insulated from water vapor and oxygen in the ambient environment, thereby ensuring long-term reliable operation of the AMOLED display screen.
