Description
Technical Field
The invention relates to the technical field of display, in particular to a quantum dot polarizer, a manufacturing method thereof and a display device.
Background
In recent years, quantum dots have attracted much attention due to their unique advantages, such as narrow emission spectrum, pure chromaticity, and tunable emission wavelength. The application of quantum dots in TFT-LCD can greatly improve the color gamut. In addition, the 'point light source' light emitting characteristic of the quantum dots enables the TFT-LCD containing the quantum dots to have the characteristic of wide viewing angle at the same time.
However, the quantum dots need to be excited by blue light (or blue-violet light), so the backlight sources of the TFT-LCD containing the quantum dots are all blue light (or blue-violet light) LEDs, and since the LEDs do not have the light emitting characteristics of quantum dot "point light sources", the blue light viewing angle (determined by the blue light LEDs) is small, and the red light and green light viewing angles (determined by the red and green quantum dots) are large, which finally causes the large viewing angle to display yellow and the color to be serious, and seriously affects the display effect. For quantum dot backlight, the light patterns of red and green light can be folded by adding an optical film, but for new technologies such as quantum dot polarizers, the method is not implemented.
Therefore, it is desirable to provide a quantum dot polarizer to solve the above problems.
