Abstract
The invention relates to a mask plate and a method for preparing an organic light-emitting display device. The mask plate can form protective layers on conductive terminals in electrode lead regions, an IC bonding region and an FPC bonding region through an evaporation process in an organic light-emitting display device preparation process, and prevents the conductive terminals in the electrode lead regions, the IC bonding region and the FPC bonding region from being corroded by water and oxygen in the production process of the organic light-emitting display device, so that the water and oxygen corrosion resistance of the organic light-emitting display device is effectively improved; and the product reliability and the product yield of the organic light-emitting display device are improved.
Description
technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a mask plate used for vapor deposition of an organic light-emitting display device resistant to water and oxygen corrosion, and a method for preparing the organic light-emitting display device. Background technique [0002] As a new generation of display devices, organic light-emitting display devices (English full name organic lighting emitting display, referred to as OLED) have incomparable advantages over traditional display devices, such as self-illumination, no need for backlight, ultra-thin display and flexible display, and driving voltage. Low, fast response, etc. However, in the production process of organic light-emitting display devices, various terminals and leads exposed to the air are easily affected by factors such as water and oxygen, and adverse phenomena such as oxidation and corrosion occur, which have a great impact on the life of organic light-emitting...
