Problems solved by technology

[0003] At present, during the production and use of OLED products, it is easy to produce no bright spots or even no bright lines. There are many reasons for no bright spots or no bright lines. Among them, electrostatic breakdown is a problem that exists throughout the life of the product. It is transmitted by signal lines. Or human hand contact and other reasons can easily transfer static electricity to the inside of the OLED device, resulting in no bright spots or lines on the internal OLED device, or even damage to the device. Therefore, the static electricity generated around the outside of the organic electroluminescent display is isolated and protected. Can effectively improve the product yield and life of organic electroluminescent devices

Abstract

The present invention provides a device with an electrostatic protection structure, comprising a base plate, a cover plate and a light-emitting component arranged between the base plate and the cover plate, the base plate has a conductive structure arranged along its periphery, and the conductive structure Continuously arranged and surrounding the light-emitting components to form a closed ring structure; the closed ring structure has a connection point connected to the ground wire. Further the present invention also provides the preparation method of the device. Adopting the above-mentioned structure can attract the static electricity around the substrate to the conductive structure, thereby effectively reducing the electrostatic interaction at the edge of the substrate and light-emitting components, solving the problem that electrostatic discharge easily causes device damage in the prior art, and improving product yield. The service life of the device is extended.

Description

Technical field[0001]The present invention relates to the field of display, and more particularly to a device having an electrostatic protection structure and a preparation method thereof.Background technique[0002]Usually, the positive and negative charges belled in any object are equal, and when contacting, friction is contacted with other objects, and due to the separation of the mechanical action, it is accumulated in an object to accumulate positive charges on one object, and another The substance accumulates negative charge and produces static electricity on each object. When some dielectric, the conductor is static, although the amount of charge is not much, since itself is very small, the electrostatic potential is high, and when the local electric field strength exceeds the air, it can be Air discharge, for the electrostatic discharge of human body, by experimentation can learn that the electrostatic discharge energy can reach 0.2 to 100 milluse, and the peak of instantaneou...
