Luminous Source Utilizing Quantum Dot, and Its Manufacturing Method and Application

Abstract

The present invention relates to the liquid crystal display technique field, and in particular to the improvement of a direct type backlight structure. The present invention provides a luminous source utilizing the quantum dot, which comprises a substrate, the substrate is installed a light bar and a mixed light body surrounding the light bar; there is a quantum dot strip provided on the top of the mixed light body, the emitting light of the light bar is emitted after the quantum dot strip refracting, the light output surface of the quantum dot strip is curved surface. The present invention also provides a manufacturing method of the quantum dot strip and a new direct type backlight composed by utilizing the quantum dot strip. The present invention makes the light output surface of the quantum dot strip be curved surface through improving the structure of the quantum dot strip, making the light output surface of the quantum dot strip be curved surface. Achieving increase of the light diffusion angle of the emitted light running through the quantum dot strip, finally, increasing the light output angle of the luminous source.
