Problems solved by technology

However, whether it is the baffle potting technology or the surface sealing technology, although it can improve the protection of the display unit, its ability to block water vapor is still the focus of improvement.
Especially when a plastic substrate is used as the thin film transistor substrate 410 and the outer cover substrate 420 in order to reduce the volume of the organic light emitting diode display, water vapor will pass from the first outer surface 412 of the thin film transistor substrate 410 and the outer cover The second outer surface 422 of the substrate 420 intrudes into the display unit 430, that is to say, the plastic substrate has a limited ability to block moisture.

Abstract

The invention discloses an electroluminescent display device which comprises a main substrate, an outer cover substrate, a plurality of display units, a seal check rubber material and at least one atom deposition barrier layer. The main substrate is provided with a first inner surface and a first outer surface. The outer cover substrate is opposite to the main substrate. The outer cover substrate is provided with a second inner surface and a second outer surface. The main substrate or the outer cover substrate comprises a plastic substrate. The display units are placed on the first inner surface. The seal check rubber material is placed between the main substrate and the outer cover substrate and is coated on the display units. The atom deposition barrier layer is coated on the second inner surface or the second outer surface.

Description

technical field [0001] The present invention relates to an electroluminescent display device, in particular to an electroluminescent display device with an atomic deposition barrier layer. The reliability and service life of the electroluminescent display device are improved through the atomic deposition barrier layer. Background technique [0002] Electroluminescent display device has always been considered as the next generation of display that may replace liquid crystal display due to its features such as no need for color filter, no need for backlight module and low power consumption. Mainstream technology. Among various electroluminescent displays, an organic light emitting diode display is a relatively mature technology at present. [0003] At present, the more common organic light-emitting diode displays are mainly packaged with glass glue. However, in the structure of the glass glue package, the space between the substrates is filled with nitrogen, so if the size o...
