Abstract

The invention relates to a method for realizing white balance based on quantum dot color conversion. The excitation light source is an LED in the visible blue light band as a backlight source, and the blue light emitted by the light source is absorbed, converted and scattered by a pixelated quantum dot color conversion film. , to achieve light white balance by mixing light in space; wherein, each pixel of the quantum dot color conversion film is composed of sub-pixels containing three primary colors of red, green and blue, and each sub-pixel has at least one blue LED backlight at the bottom The corresponding relationship of spatial position is formed with it, so that the area ratio of red, green and blue sub-pixels in the quantum dot color conversion film satisfies the following area ratio relationship, so as to realize the white balance of light output: S R n R : S G n R : S B n R = P R : P G : P B . This method is beneficial to accurately and reliably realize the white balance of quantum dot color conversion.

Description

technical field [0001] The invention relates to the field of flat panel display, in particular to a white balance realization method based on quantum dot color conversion. Background technique [0002] In the existing flat panel display technology, various colors are realized through the principle of additive color mixing, and the output intensity of each sub-pixel can be adjusted to further present realistic colors. Displays typically achieve white light by adjusting the red, green, and blue sub-pixels, also known as white balance. Therefore, using RGB color filter technology to achieve color reproduction is an indispensable key technology for flat panel display. The traditional absorbing color filter is one of them. However, absorptive color filters are usually composed of photoresist (PR) with a broad spectrum, which is prone to emission spectral overlap and color crosstalk. The desired spectral transmission can be engineered by absorbing unwanted wavelengths, but at t...
