Which backlight factory is the best?

I said, I have worked in a backlight factory for 2 years, and now I have been purchasing in a company for almost 3 years. Hehe ~ I know about this product and have the right to speak. Many suppliers often have problems such as inconsistent colors, dim light and inaccurate delivery, which is nerve-racking. I changed N suppliers, and finally introduced one: (Shenzhen Wanheda Electronics Co., Ltd.) There are relatively few backlight problems, so it is no problem to choose a professional, formal and powerful enterprise.
