Title:
MULTI-PRIMARY COLOR DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2015197461
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent a multi-primary color display device that can be improved in resolution through display using virtual pixels from having a reverse phenomenon of luminance between an input side and an output side.SOLUTION: A multi-primary color display device includes a multi-primary color display panel and a signal conversion circuit 20 which converts an input image signal into a multi-primary color image signal, and can make a display of two adjacent pixels of an input image with two virtual pixels by portioning out a red sub-pixels R, a green sub-pixel G, a blue sub-pixel B, and a yellow sub-pixel Ye constituting a pixel P to the two virtual pixels. The signal conversion circuit has a low-frequency multi-primary color signal generation part 21. The low-frequency multi-primary color signal generation part can perform multi-primary color conversion processing on a low-frequency component so that when one of the two adjacent pixels of the input image represents a specific color, the ratio of the absolute luminance of the yellow sub-pixel to the sum of the absolute luminance of the red sub-pixel and the absolute luminance of the green sub-pixel is 0.5-2.0.
