Abstract

An embodiment of the application provides a multi-primary-color conversion method and unit, a display control method and a display device, relates to the technical field of displaying and can solve the problem that the application of trichromatic signals in multi-primary-color display devices leads to the failure of implementing multi-primary-color displaying. The multi-primary-color conversion method comprises: in a first color domain having M primary colors, acquiring color coordinates and brightness value of a first color in the first color domain according to gay level values of the M primary colors corresponding to the first color; in a second color domain having N primary colors, mapping color coordinates and brightness value of a second color in the second color domain according tothe color coordinates and brightness value of the first color in the first color domain, wherein 3< / =M, 3< / =N, M is different from N, and M and N are positive integers. The multi-primary-color conversion method is used to implementing multi-primary-color conversion.

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-...
