Abstract

This invention provides a method for manufacturing a color adjustable plane color conversion device including the following steps: a, providing a fluorescence or phosphorescence material, b, uniformly mixing the fluorescence or phosphorescence material with a transparent medium and c, forming a planar color conversion layer on an electronic device to convert the short wavelength luminous spectrum emitted by the electronic device to a long wavelength luminous spectrum to vary the light or display color of the electronic device by the micro-light / color mixed effect of the two materials. A plane color conversion device is also disclosed.

Description

technical field [0001] The present invention relates to a color-tunable electronic device and its manufacturing method, in particular to a color-tunable planar color conversion device with a planarized color conversion layer and its manufacturing method. Background technique [0002] Electronic devices such as display devices, lighting devices, and measuring devices are developing towards light, thin, short, and small. Taking liquid crystal flat-panel displays as an example, if the development of light sources cannot cooperate with thin film transistors, polarizers, color filters, etc. With a planar element structure, the thickness of the overall liquid crystal flat panel display cannot be further reduced, nor can it meet the current application trend of being light, thin, short, and small. Therefore, the development of flat and thin light sources, especially white light sources, is very urgent for the entire display technology and lighting technology. [0003] Although tra...
