Title: Innovations of Chong Li in Organic Electroluminescent Devices

Introduction

Chong Li is a notable inventor based in Matsumoto, Japan. He has made significant contributions to the field of organic electroluminescent devices, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of color conversion films used in these devices.

Latest Patents

Chong Li's latest patents include a color conversion film and a multicolor-emitting organic electroluminescent device that incorporates this film. The color conversion film is designed to absorb light emitted from an organic electroluminescent part that emits blue-green light. It converts this light into visible light at a longer wavelength. The film consists of two different dyes, where the first dye is a polymer dye with an average molecular weight ranging from 1,000 to 1,000,000. This dye absorbs incoming light and transfers its energy to a second dye, which then emits light. This innovative design allows for excellent conversion efficiency without the need to increase the thickness of the color conversion film, a common limitation in conventional devices.

Another patent focuses on a color conversion film that maintains sufficient conversion light intensity without increasing its thickness. This film also utilizes a polymeric dye material composed of a first dye unit and a second dye unit. The first dye unit absorbs incident light and transfers energy to the second dye unit, which emits light. This advancement is crucial for developing multicolor light-emitting organic electroluminescent devices.
