A 32 inch Two‐dimensionally Integrated Fluorescent Lamp (TIFL), the largest size in the world, has been developed at the first time. It is integrated into a backlight unit without using double brightness enhancement film (DBEF). The luminance of a TIFL backlight unit is 12500 nits at 140 watts of power consumption and its luminous efficacy is 55 lumens/watt at very high correlated color temperature. The color coordinate is 0.261/0.287 on the LCD. The usage of TIFL simplifies backlight assembly process and removes expensive optical sheets. As a result, LCD TVs employing TIFL will rapidly expand its market share in the large size TV application.
