Problems solved by technology

Among them, the OLED display substrate (Panel), as a core component of the OLED display module, is prone to generate static electricity when it is bonded with 2D or 2.5D cover glass (Cover Glass), which affects the service life of the OLED display substrate.
During the Electro-Static discharge (ESD) test, the static electricity on the cover glass cannot be discharged, resulting in ESD failure and easy display abnormality of the product
On the other hand, when the assembly and bonding of the display module is out of position or the process capability is insufficient, it is easy to cause light leakage, which affects the display effect of the OLED display substrate.
In addition, external water vapor, oxygen, etc. can easily enter the encapsulation layer (Encap) on the OLED display substrate, which further affects the service life of the product.

Abstract

The invention discloses a display module and a display device. The display module comprises a cover plate, a display substrate, a middle frame and a first electrostatic conductive structure. The coverplate is positioned on the light-emitting side of the display substrate, and the display substrate is positioned between the cover plate and the middle frame. The first electrostatic conductive structure is used for conducting electrostatic generated on the cover plate to the middle frame for electrostatic discharge. The display module and the display device provided by the invention can solve the problem that the static electricity on the cover plate cannot be released to cause abnormal display of the product, and effectively ensure the service life of the product.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] At present, rigid OLED display modules are generally used as display components of electronic equipment, and are widely used in various electronic products. Among them, the OLED display substrate (Panel), as a core component of the OLED display module, tends to generate static electricity when it is laminated with 2D or 2.5D cover glass (Cover Glass), which affects the service life of the OLED display substrate. During the Electro-Static discharge (ESD for short) test, the static electricity on the cover glass cannot be discharged, resulting in ESD failure and easy display abnormality of the product. On the other hand, when the assembly and bonding of the display module is out of position or the process capability is insufficient, it is easy to cause light leakage, which affects the display effect of the OLED ...
