Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display device and a method for manufacturing a panel. Background technique [0002] The cover plate and the substrate in the conventional organic light emitting diode display panel form a cavity, and the display device in the above conventional organic light emitting diode display panel is arranged in the cavity. [0003] During the working process of the above-mentioned conventional OLED display panel, water vapor is easily mixed into the chamber. [0004] When a lot of water vapor accumulates in the chamber, the display device will be damaged. [0005] Therefore, in order to make the OLED display panel have a longer service life, it is necessary to keep the chamber dry. Contents of the invention [0006] The object of the present invention is to provide a method for manufacturing an organic light emitting diode display device and a panel, w...
