An organic light-emitting diode (OLED) display panel and a mask are disclosed. The OLED display panel includes a first film layer, and a second film layer disposed on the first film layer and made of an organic material. The second film layer includes an edge slope corner formed at an acute angle less than a predetermined value. Since the edge slope corner of the second film layer is formed at the acute angle less than a predetermined value, a technical problem existing in conventional OLED display panels that edge slope corners of organic layers are formed at approximately a right angle can be mitigated.

Mask capable of forming edge slope corner of organic film layer

A touch panel and a display device thereof are provided, including a first metal layer, an insulating layer, and a second metal layer. The second metal layer includes a plurality of first metal lines and a plurality of second metal lines, and the first metal lines and the second metal lines are interlaced with each other to form a mesh pattern. The insulating layer is disposed with a via hole, and the first metal layer is electrically connected to the second metal layer through the via hole. A dummy pattern is disposed in a non-functional area of the first metal layer.

A method and device for harmless treatment and recycling of waste refrigerators. Plastic parts, electrical boxes, compressors, and condensers are disassembled at a disassembling station. Refrigerants from compressors are recycled at a fluoride-extracting station. Refrigerator bodies and doors are transferred to a double shaft shredder and a rolling crusher for crushing. Crushed materials are sorted out by wind force, by a self-discharge type iron remover made of permanent magnet and a cylindrical iron remover for magnetic separation. The device is placed in an enclosed workshop equipped with a multistage ventilation system, a protective device of nitrogen, a device for spraying, dedusting, and cooling, and an on-line detection and alarm control device for cyclopentane gas concentration, polyurethane dust concentration, and temperature. The method and device have low manufacturing and operating costs and are dustproof, explosion proof, environmentally friendly and has excellent recycling effects.
