The projection device includes a light source, a liquid crystal on silicon (LCoS) panel, and a circuit. The circuit is configured to obtain a target image including a target pattern, and generate two content images. Each content image includes a duplicated pattern of the target pattern, and the duplicated patterns are off-axis shifted to the same coordinate when performing a computer-generated hologram (CGH) algorithm, so as to generate a phase image. The LCoS panel is driven according to the phase image to display a reconstructive image at a reconstructive distance.

The present invention discloses a video data display device including a plurality of driving circuit. Each driving circuit includes a status controller, a data receiver, an output data generation unit, and an output buffer. The status controller couples with the data receiver, the output data generation unit, and the output buffer. The status controller generates a status signal based on the operation information of the data receiver, the output data generation unit, or the output buffer. The status controller transmits the status signal to the status controller of other driving circuits.

A display device has an image processing unit that determines an error for a pixel location that is based on the difference between an input color dataset and an output color dataset. The error is fed back to the image processing unit to propagate and spread across other neighboring pixel locations. In generating the output color dataset, an error-modified dataset that includes the input dataset and the error may first be generated. The error-modified dataset is examined to ensure the color values fall within the display gamut. The color dataset is also quantized and dithered to make the output dataset having a bit depth that is compatible with what the light emitters can support. Lookup tables and transformation matrices may also be used to account for any potential color shifts of the light emitters due to different driving conditions such as driving currents.

A piston-mode spatial light modulator (SLM) includes a mirror and an electrode. The electrode is attached to the mirror. The electrode includes: a rigid body; and three spring legs coupled to the rigid body and configured to displace the rigid body responsive to an electrostatic force applied to the electrode.

This document discusses, among other things, an apparatus comprising a pump configured to deliver insulin, a processor, and a user interface including a bistable display. A display element of the bistable display is placed in one of two stable orientations upon application of a biasing voltage and stays in the stable orientation when the biasing voltage is removed. The processor includes a display module configured to display a non-blank reversion display screen on the bistable display when no input is received at the user interface after a specified time duration, and to recurrently change the reversion display screen until input is received at the user interface.

According to one embodiment, a first substrate includes a pixel electrode, a common electrode and a sub-pixel area including a first area and a second area. The first area includes an area where the pixel electrode exists, an axial area extending in a second direction, and branch areas extending from the axial area to a first side of the first direction. The second area includes an area where the pixel electrode does not exist, and a first gap area extending in the first direction, at a position between the adjacent branch areas. A maximum value of a first voltage applied to the pixel electrode in a first mode is higher than a maximum value of a second voltage applied to the pixel electrode in a second mode.

In methods and apparatus for increasing efficiency and optical bandwidth of a microelectromechanical system piston-mode spatial light modulator, an example apparatus includes: an electrode with spring legs; a base electrode; a mirror displacement determiner to determine a periodic signal corresponding to a displacement distance of the electrode beyond an instability point of the electrode; and a voltage source to output a periodic voltage to the base electrode in response to the periodic signal. The periodic voltage causes the spring legs to vary displacement of the electrode with respect to the base electrode according to the periodic voltage. The displacement includes distances beyond the instability point.

A luminous display substrate includes a base substrate, a light reflective and electrically conductive film layer on the base substrate, and a light-transmittance metal film layer on a side of the light reflective and electrically conductive film layer away from the base substrate. A side of the light reflective and electrically conductive film layer adjacent to the light-transmittance metal film layer is recessed towards the base substrate to form a curved surface.
