Patent ID: 10706792

Abstract:
A light source section 21 includes a red light source 22r, a green light source 22g, and a blue light source 22b, and one frame period is divided into four subfield periods. Light sources of each color respectively emit light in blue, green, and red subfield periods, and the red light source 22r and the green light source 22g emit light in a yellow subfield period. Light emission intensity of the blue light source 22b in the blue subfield period is set to twice light emission intensities of the red light source 22r and the green light source 22g in other subfield periods. Color breakup is reduced by displaying the yellow subfield, and light utilization efficiency improved by setting transmittance of a light modulation element 16 to 100% when a white signal by which each gradation of red, green, and blue becomes maximum is input. With this, a field sequential type display device which can reduce color breakup and has high light utilization efficiency is provided.
