The present disclosure provides an organic electroluminescent display backpanel, cover and device, wherein the backpanel comprises a backpanel body and a plurality of supporting columns, the backpanel body comprises a substrate and an array of organic electroluminescent elements formed on the substrate, and the supporting column is disposed at a side of the array of organic electroluminescent elements away from the substrate.

Organic electroluminescent display backpanel, cover and device

A rolling apparatus, comprising a mounting bracket, a supporting platform and a rolling device; the mounting bracket is disposed above the supporting platform, and the rolling device is disposed on the mounting bracket so as to be located above the supporting platform; wherein the supporting platform is configured to support a display panel thereon; and the rolling device is configured to perform a rolling process on the display panel at a predetermined pressure. A rolling method, comprising supporting a display panel; and rolling the display panel at a predetermined pressure to cause an observable defection resulted from a foreign substance within the display panel. With the rolling apparatus and the rolling method, the display panel containing foreign substance will be detected as a defective product during the Cell Test so as not to enter the modular process, thereby avoiding any waste of module materials.

Rolling apparatus and rolling method

The present invention provides an array substrate, a display panel and a display device, which can be used for solving the problem of an existing array substrate that ESD occurs between a data line and a repair line to cause short-circuiting of the data line and the repair line so as to pull down the voltage of the data line. The array substrate includes a plurality of main signal lines, at least one main repair line arranged to be crossed with and insulated from the main signal lines at the peripheral area of the array substrate, and a redundant repair line, and the redundant repair line is arranged to be insulated from the main repair line; wherein the redundant repair line includes at least one redundant repair part, and the resistance of each redundant repair part is smaller than the resistance of each main repair line.
