Zusammenfassung:	The invention belongs to the technical field of LED display screens, and particularly relates to a color gamut conversion method and device and electronic equipment. The color gamut conversion method comprises the following steps: measuring a color coordinate when a single-color lamp of an LED display screen is fully lighted by using acquisition equipment; converting the color coordinates of the monochromatic lamps into tristimulus values corresponding to the monochromatic lamps; performing color gamut conversion calculation on the tristimulus value of the monochromatic lamp to obtain a conversion factor; and multiplying an input color gamut coordinate target value by the conversion factor to obtain a final target value. The invention can solve the problem that the target value of the color coordinate is not accurate enough and exceeds the reference color space during the light supplementing operation. 本发明属于LED显示屏技术领域，具体涉及一种色域转换方法、装置和电子设备。一种色域转换方法，包括：利用采集设备测量LED显示屏单色灯全亮时的色坐标；将单色灯的所述色坐标转换成对应单色灯的三刺激值；对单色灯的所述三刺激
