White light-emitting diodes (LEDs) are used as a light source in many liquid-crystal displays (LCDs), with blue light generated as a spectral distribution characteristic of white LEDs being potentially harmful to the human retina. We propose a method for reducing the blue light only by calibration and profiling without adjusting. Specifically, this paper attempted to verify the efficacy of colourimetric characterisation for reducing or controlling the blue light. Based on the test results of LCD monitors that use a variety of LED light sources, the white LED exhibited maximal blue light emission at 450 nm, and using colourimetric characterization reduced this emission by ~36%. The proposed method is a novel approach for examining the relationship between display technologies and the human retina.
