摘要:
A multi-primary color display device according to the present invention includes pixels, each having a plurality of sub-pixels. The plurality of sub-pixels include first, second, third and fourth sub-pixels for displaying first, second, third and fourth colors having first, second, third and fourth hues. The second and third hues are adjacent to the first hue on both sides thereof on an a*b* plane of an L*a*b* colorimetric system. When a color displayed by each pixel changes from black to an optimal color of the first hue, luminance values of the plurality of sub-pixels are set such that the luminance value of the first sub-pixel starts to be increased and also the luminance values of the second and third sub-pixels start to be increased at a rate of increase lower than the rate of increase of the first sub-pixel.

摘要:
A multi-primary-color liquid crystal display device according to the present invention is adapted to conduct a display operation in at least four primary colors. The device has a plurality of pixels that form at least two different types of subsets. The device can perform rendering processing in which at least one of the pixels that form a first one of the at least two different types of subsets lends a luminance to a second type of subset. Each pixel includes a first sub-pixel and a second sub-pixel that could have mutually different luminance. The second type of subset borrows a luminance from one of the first and second sub-pixels of the at least one pixel that has the higher luminance.
摘要:
A signal conversion circuit (20) is used for a multiple-primary color liquid crystal display device (100) which performs color display using four primary colors of red displayed by a red-sub pixel (R), green displayed by green-sub pixel (G), blue displayed by blue-sub pixel (B), and yellow displayed by yellow-sub pixel (Ye), and converts an input three-primary color video signal into a multiple-primary color video signal corresponding to four primary colors. The signal conversion circuit (20) performs signal conversion such that a gray scale level of the yellow-sub pixel (Ye) is higher than a gray scale level of the green-sub pixel (G) in at least some cases from among cases in which a red gray-scale level r, a green gray-scale level g, and a blue gray-scale level b which are displayed by the three-primary color video signal satisfy a relationship of r>g>b.

A display element (10) includes an upper substrate (first substrate) (2), a lower substrate (second substrate) (3), and a polar liquid (16) that is sealed in a display space (S) formed between the upper substrate (2) and the lower substrate (3) so as to be moved toward an effective display region (P1) or a non-effective display region (P2). A display control (DC) supplies predetermined reset signals to signal electrodes (4), reference electrodes (5), and scanning electrodes (6) so that the polar liquid (16) in each of all pixel regions (P) is moved to an initial position that is set on the effective display region (P1) side or the non-effective display region (P2) side opposite the scanning direction before the scanning operation is performed.

A method of making a micro corner cube array includes the steps of: preparing a substrate, at least a surface portion of which consists of cubic single crystals and which has a surface that is substantially parallel to {111} planes of the crystals; and etching the surface of the substrate anisotropically, thereby forming a plurality of unit elements for the micro corner cube array on the surface of the substrate. Each of these unit elements is made up of a number of crystal planes that have been formed at a lower etch rate than the {111} planes of the crystals.
