We propose an effective strategy for improving the color uniformity of phosphor-coated LEDs (pc-LEDs) by employing transparent bamboo (TB) as an optical management material. The “yellow ring effects” existing in pc-LEDs cannot be ignored, and it is significant to alleviate this effect by introducing some strategies. The TB made by lignin modification treatment and polymer impregnation is used in t...Show More
Nowadays, direct current-drive (DC-drive) is the mainstream method of driving electroluminescence (EL) devices such as quantum-dot light-emitting diodes (QLEDs). In contrast, alternating current-drive (AC-drive), as an alternative to DC-drive, has achieved lots of significant research results in recent years. And AC-drive is expected to reduce equipment manufacturing costs by reducing the use of p...Show More
