First of all, this is a well written article, but the infomation below in the quotes are incorrect.
Companies like Tianma, JingDongFang(BOE) are not after market factories, instead, they are actually display glass factories, they produce OEM displays for brands like Huawei, Oppo, Vivo etc.
Several of the large factories you mentioned are in the stock exchange market in China and worth billions of USD.
So why do people think that Tianma produce after market displays, because a lot of the trading companies and wholesalers in China don't even know what they are selling...
Here is the truth....after market manufacturers buy display glass from factories like Tianma and Boe, yes, only the display glass, not assembly, not backlight, not TP...
You can ask any REAL FACTORY owners and distributors in the top tier in China, they will tell you the same, since you mentioned longteng after market display, hmmm, the owners' surname is Xiao.
Please excuse the bad grammer and English, as I am not a native English speaker, nor did I study English litrature.
