For example, it would appear that more than 90 % of the backlight module needs are supplied to flat panel vendors by Taiwanese companies. However, those Taiwanese companies depend completely on Japanese firms for key components-including polarizers-accounting for 70 % of their total costs, and they have no scope for negotiating lower prices.
以背光模組為例，目前台灣在背光模組供貨給面板廠的自給率表面上超過 90％，但其中佔成本 7 成的關鍵原材料，包括偏光膜等，幾乎都要倚賴日本廠商供貨，而且沒有議價空間。
