Abstract

The invention discloses a display device using quantum dot fluorescent powder, which mainly comprises a luminous unit and a color filter. The luminous unit is provided with a luminous chip and multiple quantum dot fluorescent powder and generates colored light, and the emission spectrum is provided with a first blue light peak wavelength, a first green light peak wavelength, and a first red light peak wavelength. The color filter is arranged on a luminous path of the luminous unit, so that the colored light emitted by the display device penetrates the color filter, and the transmission spectrum is provided with a second blue light peak wavelength, a second green light peak wavelength, and a second red light peak wavelength. The first blue light peak wavelength, the first green light peak wavelength and the first red light peak wavelength are respectively matched with the second blue light peak wavelength, the second green light peak wavelength and the second red light peak wavelength so as to improve the expression of the display device of colors. The display device using the quantum dot fluorescent powder has better color expression and brightness.

Description

technical field [0001] The invention relates to a display device and a manufacturing method thereof, in particular to a display device using quantum dot fluorescent powder and a manufacturing method thereof. Background technique [0002] A liquid crystal display device is mainly composed of two parts: a liquid crystal panel and a backlight module. Since the liquid crystal panel itself does not emit light, the light generated by the backlight module is used, and the liquid crystal molecules in the liquid crystal panel pass through the light to generate images. How to match the light generated by the backlight module with the color filter in front of the liquid crystal panel has become a major research topic in this field in order to make the generated image have good color performance. [0003] At present, the light sources widely used in the backlight module in the industry mainly include cold cathode fluorescent lamp (CCFL) and light emitting diode (light emitting diode, L...
