At present, BOE has announced that glass-based Mini LED backlight and direct display have entered the mass production stage. In recent years, Mini LED has made substantial progress in technology, products, capacity and other aspects, including Samsung, LG, TCL, Xiaomi and many other brands have launched Mini LED products. Further highlights the Mini LED industry chain has been gradually improved, so that more terminal applications become possible. In the future, there will be more added value between the upstream and downstream products of Mini LED, and the degree of industry integration will be more obvious.
By the end of 2005, China had adopted LED traffic lights from urban to rural areas. Our country is also the fastest, most common and most used LED traffic signal lamp in the world. The 2008 Beijing Olympics had a notable presence, LED products for large venues. Since then, LED products have been promoted vigorously in our country and have entered more and more households. From 2008 to 2009, the country launched a demonstration project to promote more than 300,000 LED lighting fixtures in 20 cities to achieve LED lighting technology, cost and scale production. The 2022 Winter Olympics will also feature leds. Urban lighting is also moving towards the era of energy saving, LED application market is becoming larger and larger.
When the silver paste is bonded and electrically connected, if the silver paste is poorly controlled, another failure mechanism will be introduced: the silver paste extends to the surface of the chip, resulting in short circuit and leakage. After the test on the board, it was found that the LED showed batch failure, and the mode was that there was a large leakage between the two electrodes of the LED. After opening the LED, it was found that the conductive adhesive was too much, and the silver paste extended to the surface of the chip when the chip was bonded, forming a short circuit channel with the gold wiring without passivation layer on the chip.
