Abstract

Disclosed is a primary color conversion method, which may expand primary color signals that are applicable to a display device. The primary color conversion method includes: acquiring color coordinates and a brightness value of a first color in a first color gamut having M primary colors according to gray-scale values of the M primary colors corresponding to the first color; and mapping the color coordinates and the luminance value of the first color in the first color gamut to color coordinates and a brightness value of a second color corresponding to the first color in a second color gamut having N primary colors. 3≤M, 3≤N, M is different from N, and M and N are positive integers.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a multi-primary color conversion method and its converter, a display control method, and a display device. Background technique [0002] With the continuous development of display technology, display devices have been widely used in electronic products, such as mobile phones, televisions, computers and other products. At present, the three-primary-color (RGB) display device displays a limited color gamut, which cannot meet the user's requirements for screen expressiveness. In order to solve the above problems, in the prior art, a multi-primary color display device with more than three primary colors is proposed. However, due to the impact of industry chain problems, it is currently impossible to directly provide multi-primary color display signals to multi-primary color display devices. In this case, if the three-primary-color display signals are directly applied to the multi-...
