in fact Sony and Samsung do business together 50/50 in a joint venture called S-LCD Corporation. This 3rd part company was formed as a LCD panel manufacturing operation that would supply the needs of the two companies. Neither company supplies the other for LCD panels; the panel is only one part of a tv, the processing engine is what drive that LCD panel. Though the raw panels come from the same factory, Sony and Samsung panels do often in feature different specifications. None of this has ever been a secret...![]()
This is true ... Panel is just a part of it but other factors depend on their technologies (actually they try to distinguish the products by innovating new technology to provide best picture experience)
