Several South Korea-based manufacturers including Heesung Precision Co. Ltd, Taesan LCD Co. Ltd and Wooyoung Digital Co. Ltd, are now developing new technologies for LCD backlights.

Manufacturers believe that the next generation of high-luminance backlight units (BLU) applied to light guide panels are the upcoming trend in backlighting for LCD TVs, since light guide panels with polymethylmethacrylate (PMMA) integrated with the BLUs have the advantage with its compact in size.
