P‐3.8: Research on Improving Blueness Around QD + Edge‐in Blue LED Architecture Modules

Abstract

In this paper, a high efficient computing method which could solve Blueness around QD + edge‐in blue LED architecture modules was proposed. The yellow phosphor was excited by blue light to compensate for the color temperature difference caused by the low efficiency of the edge QD excitation. The visually intuitive result was that the blue shadow of the surrounding area was improved, and the naked eye distinguishes the center and the surrounding color temperature basically the same. And two factors of yellow ink which have impact on blueness around the MDL were experimentally studied in this paper, then found out and summarized the most optimum conditions.
