Abstract: A display device includes a light modulation layer and a light source. The light modulation layer is disposed between a pair of transparent substrates, has determined refractive index anisotropy, and includes plural light modulation elements which differ in responsiveness to an electric field generated by electrodes formed on a transparent substrate. The light source emits light of a determined color incident on the light modulation layer from a side of the light modulation layer. When the electric field is not generated, the light modulation layer transmits the incident light emitted from the light source. When the electric field is generated, the light modulation layer scatters the incident light and emits scattered light to a transparent substrate.

Abstract: A display system includes a controller and an image display panel. The controller includes a signal transmitter configured to output at least a vertical synchronization signal to a plurality of image-capturing apparatuses; and a synthesizer configured to provide synthesized image signals in units of lines obtained by synthesizing, in units of lines, image signals in units of lines output from the respective image-capturing apparatuses at a timing corresponding to a horizontal synchronization signal formed in a predetermined cycle based on an output timing of the vertical synchronization signal. The image display panel is configured to display sequentially, in units of lines, the synthesized image signals in units of lines.

Abstract: In a display device, pixels each including first to fourth subpixels that respectively display first to third primary colors and fourth color are arranged on an image display panel. A lighting unit emits light to the panel from the rear thereof. A control unit calculates a required luminance value for each block of the display surface of the panel based on an input image signal, determines a light source lighting amount of the lighting unit based on luminance distribution information on the lighting unit so as to satisfy the required luminance value, generates luminance information on each pixel based on the luminance distribution information and light source lighting amount, generates an output image signal that drives the subpixels based on the luminance information and input image signal, controls the lighting unit by the light source lighting amount, and controls the panel by the output image signal.

Abstract: A display device includes a signal processing unit that receives input signals, and calculates output signals to a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The signal processing unit calculates a frequency of pixels belonging to each of a plurality of partitions using a light quantity of a surface light source. The signal processing unit calculates an index value for each of the partitions by at least multiplying the cumulative frequency being obtained by sequentially adding the frequency of pixels from a partition having the maximum light quantity among the partitions, and the number of partitions representing a position of a partition to which the cumulative frequency belongs counted from the partition having the maximum light quantity. The signal processing unit controls luminance of the surface light source based on a partition in which the index value exceeds a threshold.
