A display device with low power consumption is provided. A display device having high visibility regardless of the ambient brightness is provided. The display device includes a light-receiving element, a display element, a first transistor, and a second transistor. One of a source and a drain of the first transistor is electrically connected to one electrode of the light-receiving element. The one of the source and the drain of the first transistor is electrically connected to one of a source and a drain of the second transistor. The display device has a function of, by turning on the second transistor, changing the gray level of the display element in accordance with the amount of light detected by the light-receiving element.

Described is a display system comprising a light source, a scanning assembly, and a controller. The light source includes a first plurality of emitters forming a column that emits a first color. The light source also includes a second plurality of emitters forming a column that emits a different color. The scanning assembly includes a reflective surface rotated by the controller using a control signal having a nonlinear, pulsed waveform. The controller drives the first plurality of emitters and the second plurality of emitters in sequence, during respective portions of the nonlinear waveform, and in synchronization with rotation of the reflective surface such that light emitted by the first plurality of emitters and the second plurality of emitters is reflected onto a same pixel of an output image. The controller also adjusts emission durations of individual emitters to compensate for changes in the rotational speed of the reflective surface.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

Light from an array of laser light sources are spread to cover the modulating face of a DMD or other modulator. The spread may be performed, for example, by a varying curvature array of lenslets, each laser light directed at one of the lenslets. Light from neighboring and/or nearby light sources overlap at a modulator. The lasers are energized at different energy/brightness levels causing the light illuminating the modulator to itself be modulated (locally dimmed). The modulator then further modulates the locally dimmed lights to produce a desired image. A projector according to the invention may utilize, for example, a single modulator sequentially illuminated or separate primary color modulators simultaneously illuminated.

An FPGA of a control device performs the following control in a case where laser light which is spatially modulated according to a Lissajous curve is scanned and an intensity of the laser light is time-modulated according to an image formed for each partial region divided from a scanning region of the laser light to form the image. The FPGA performs control of a region surrounded by a grid line passing through a plurality of intersections which are continuous in an X direction and a grid line passing through a plurality of intersections which are continuous in a Y direction that intersects the X direction among a plurality of intersections of the Lissajous curve to be the partial region.

A projector includes a DMD that forms an image, a projection lens that projects the image formed by the DMD on a projected surface, and a display control unit that controls an image forming operation of the DMD. The display control unit forms a frame image by sequentially forming a plurality of images using a combined pixel which is configured of a plurality of pixels, and with respect to temporally continuous two images, the display control unit forms one image at a position that is shifted by a distance that corresponds to the pixel pitch of the DMD in a predetermined direction relative to the other image.

Provided is a spatial light modulator device that includes a light modulation unit, a first memory, and a second memory. The light modulation unit performs a transition operation between a first state and a second state. In the first memory, data for specifying which one state of the first state and the second state the light modulation unit is to be put in is written during a transition time in which the transition operation is performed. In the second memory, the data retained in the first memory is written after the transition time ends and the second memory supplies the data to the light modulation unit.

Display Pixel Design and Control for Lower Power and Higher Bit Depth Craig Michael Waller A method to generate pixel control signals more rapidly and with less overhead is disclosed. The method generates pixel control signals for a first block of pixels having a first first-block pixel and a second first-block pixel and a second block of pixels having a first first-block pixel and a second second-block pixel. A first-block base control signal that is shared by the first block of pixels is generated. A first first-block sharpening control signal for the first first-block pixel is generated and a first second-second-block sharpening control signal for the first second-block pixel is generated. The first first-block pixel control signal is generated using the first first-block sharpening signal and the first-block base control signal. The first second-block pixel control signal is generated using the first second-block sharpening signal and the second-block base control signal.
