The chromaticity calculation method and chromaticity calculation method of the display device

摘要

The present invention discloses a chromatic calculation method of a display device. The display unit includes a quantum dot backlight module and a first polarizing plate installed on the light exit side of the quantum dot backlight module, the quantum dot backlight module is a light guide plate, a quantum dot thin film layer installed on the light exit side of the light guide plate, and installed on the light incident side of the light guide plate Includes a light distribution source. The method is to obtain a correction spectrum of the quantum dot backlight module through a reference polarizing plate, and based on the correction spectrum and the measurement spectrum obtained by measurement of the backlight module, the quantum dot backlight module when the first polarizing plate is installed on the light-emitting side of the quantum dot backlight module. By obtaining an actual spectrum of, that is, a modified spectrum, the chromaticity deviation phenomenon caused by the secondary excitation of the first polarizing plate is accurately simulated, providing a basis for the quantitative design of a display device including a quantum dot backlight module. The present invention further discloses a method for calculating chromaticity of a display device.
