Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] Welding the metal plate is used to attach the glass powder (frit seal), and the frit seal is coated on the opening of the metal plate, and the energy of the laser is reflected by the metal plate, so that the frit seal is melted and solidified again. In order to absorb enough laser energy, the area of ​​the welded metal plate needs to be larger than a preset threshold. However, a large-area metal plate is likely to cause charge accumulation, resulting in ESD,...

Abstract

The embodiment of the invention discloses a display device and a welding metal plate. The welding metal plate not only is used for attachment of glass powder but also is used for receiving energy of laser for fusing of the glass powder. The welding metal plate is composed of at least two metal laminated layers; each of the at least two metal laminated layers has a snake-shaped routing type metal line or mesh structure; and the two adjacent metal laminated layers among the at least two metal laminated layers are spaced by an interlayer medium. A medium hole is formed in an intersection point part of the two adjacent metal laminated layers at the interlayer medium; and the two adjacent metal laminated layers are connected electrically through the medium hole. Therefore, charge accumulation on the welding metal plate is reduced and thus electrostatic discharging is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a welded metal plate and a display device. Background technique [0002] Currently, AMOLED (Active-matrix organic light emitting diode) display devices are widely used in various products. When encapsulating the AMOLED display panel, a frit process can be used, and a frit metal plate can be arranged between the two substrates that need to be packaged together to reflect the energy of the laser, so that the frit material can be melted and solidified again. In order to increase the adhesion to the frit material, openings can be provided in the welded metal plate. [0003] However, in the AMOLED display panel, the welded metal plate used to attach the frit material is a single large-area metal plate. Due to the huge area, it is easy to cause charge accumulation, resulting in Electro-Static Discharge (ESD), thereby damaging the substrate. on the electronics. Contents of the inve...
