Abstract
In order to make the liquid crystal display (LCD) panel thinner, brighter and no-Hg containing, the light emitting diodes (LEDs) are generally beginning to replace conventional cold cathode florescent lamp (CCFL) as light sources for LCD backlight unit (BLU). The thermal management and cost are consideration caused by more LEDs used for larger size BLU. For saving the fabrication cost and considering the luminous uniformity of most commercial BLU, a novel C-like linear tube is fabricated by precision and micromachining technique. The LED C-like linear tube is not only decreasing LEDs for BLU but also increasing the optical efficiency for emitting the light into the BLU. The C-like linear tube is proposed to replace CCFL tube for thin film transistor (TFT) LCD applications.
