The arithmetic circuit has a function of outputting the first image data stored in the frame memory to the display as second image data on the basis of the second coordinates.

An operation guide apparatus includes a display and a processor. The display displays, on a display screen, operation guide information for providing a guide on an operation for continuously using a device. The processor performs processing to enable an operator who is doing the operation with such a posture that the operator is unable to see the operation guide information displayed on the display screen to recognize the operation guide information.

The display panel includes a display area including a pixel area, and a light blocking area which is adjacent to the pixel area, a first light emitting device which is in the pixel area of the display area and emits a light having a first wavelength range, a second light emitting device which is in the light blocking area of the display area and emits a light having a second wavelength range different from the first wavelength range, and a discoloration layer which is on the second light emitting device and is color-changeable by the light having the second wavelength range, the discoloration layer defining a first opening exposing the pixel area to outside the discoloration layer.

An apparatus includes a light source configured to emit a light beam based on image data, a projection unit configured to project the light beam onto a pupil of a user, and at least one processor and a memory coupled to the processor storing instructions that, when executed by the processor, cause the processor to function as: an obtaining unit configured to obtain position information on a projection area through which the light beam to be projected onto a retina of the user passes, and a control unit configured to control a projection image to be projected onto the retina with the light beam based on the image data. The control unit controls the light source such that the projection image is changed based on the position information on the projection area and a position of the light beam.

An image forming system includes a spatial light modulator (SLM) including a plurality of pixels. Each pixel is configured to diffract incident light and cause the diffracted light to exit the SLM, where a first diffraction order of light exiting the SLM passes through a first exit pupil and higher diffraction orders of light exiting the SLM pass through additional exit pupils having different positions from the first exit pupil. Control logic operatively coupled to the plurality of pixels is configured to control each pixel to control its modulation of the light incident on the pixel and cause the plurality of pixels to collectively form an image at each exit pupil. A light source is configured to emit incident light toward the SLM. A resampling layer is configured to subsample each pixel electrode with two or more samples per pixel to increase a spacing between each exit pupil.

A video display device includes LED pixels, a memory, and a processor. The processor receives video data that includes video pixels that correspond to the LED pixels. For at least some of the video pixels, the processor calculates a viewing angle for the LED pixel based on (i) a 3D location and optical axis vector for the LED pixel and (ii) a 3D location of a viewer of the LED pixel. The processor calculates a gain factor for the LED pixel based on the viewing angle and a relationship between pixel intensity and pixel viewing angle for the LED pixel. The processor calculates a compensated brightness for the LED pixel based on the gain factor and a brightness of the video pixel. The processor causes the LED pixel to emit light having the compensated brightness.

A display device includes: a common electrode and a pixel electrode that includes a horizontal stem, a vertical stem, and a branch.
