Embodiment Construction

[0032] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0033]The present invention firstly provides a method for improving the yellowishness of the display screen of a quantum dot liquid crystal display. The quantum dot liquid crystal display targeted by the method includes a backlight module and a quantum dot liquid crystal panel arranged oppositely. The dot liquid crystal panel provides a display light source so that the quantum dot liquid crystal panel displays an image picture. The quantum dot liquid crystal panel includes a plurality of pixel units arranged in an array, and each pixel unit includes red sub-pixels, green sub-pixels and blue sub-pixels arranged in parallel. A color sub-pixel, wherein both the red sub-pixel and the green sub-pixel include a quantum dot film.

Abstract

The invention provides a method for improving the yellowish display frame of a quantum dot liquid crystal display and a quantum dot liquid crystal display. The method for improving the yellowish display frame of the quantum dot liquid crystal display comprises the following steps: the number ratio of the red sub-pixels, green sub-pixels and blue sub-pixels in each pixel unit is set to be 1:1:a, wherein a> 1, the brightness value L0 corresponding to the original gray scale signal G0 of the blue sub-pixel in the front case for each pixel unit is acquired by looking up a table, the actual gray scale signals are input for all the blue sub-pixels in the pixel unit, so that the sum of the luminance values of all blue sub-pixels in the front case in each pixel unit is equal to L0, that is, the total brightness of the blue sub-pixels in the front case is kept constant, and the actual gray scale signal input of the single blue sub-pixel is reduced, so that the total brightness of the blue sub-pixels in the squint case is relatively improved, and therefore, the problem that the display frame of the quantum dot liquid crystal display is yellowish under a large viewing angle is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for improving the yellowishness of a display screen of a quantum dot liquid crystal display and a quantum dot liquid crystal display. Background technique [0002] With the development of science and technology and the progress of society, people are increasingly dependent on information exchange and delivery. As the main carrier and material basis of information exchange and transmission, display devices have become a hotspot and highland that many scientists engaged in information optoelectronic research are vying to seize. [0003] Quantum Dots (QD for short) are extremely tiny inorganic nanocrystalline particles that are invisible to the naked eye. Whenever stimulated by light or electricity, the quantum dots will emit colored light. The color of the light is determined by the composition, material and size of the quantum dots. Generally, the smaller the particle, ...
