A system, includes a controller configured to obtain, for an image frame stored in a frame memory image, data associated with a color component and generate dithered bit planes having a dither noise pattern, the dithered bit planes including time repeated bit plane sequences in the image frame. The system also includes a spatial light modulator (SLM) coupled to the controller. The SLM is configured to project an image of the image frame according to the dithered bit planes. Additionally, the system includes a light source optically coupled to the SLM. The light source is configured to provide light for projecting the image.

The present disclosure relates to a driving method of graphene display device and the graphene display devices. The method includes obtaining target point coordinates of a pixel within a color gamut system by RGB grayscale values to be inputted by the pixels, obtaining chromaticity coordinate (CIE) or a brightness of a first dynamic sub-pixel and a second dynamic sub-pixel of the pixel according to a location relationship of three color gamut blocks divided by a RGB color gamut within the target point coordinate and a gamut coordinate system, determining a driving voltage of the pixel in accordance with the CIE or the brightness of the first dynamic sub-pixel and the second dynamic sub-pixel, and outputting the driving voltage to the pixel. The graphene display device may for quickly, effectively, and more convenient realize high color fidelity so as to enhance the performance of LCDs.

A layered content display system includes a networking device coupled to a network, a source device configured to display first content information on a source device screen, a display device, and a sink device coupled to the networking device, the source device, and the display device. The sink device receives an identification of the first content information from the source device. The sink device then retrieves a first subset of the first content information from the source device, and a second subset of the first content information from the network through the networking device. The sink device then provides the second subset of the first content information layered with the first subset of the first content information for display on the display device such that the first content information displayed on the display device is substantially similar to the first content information displayed on the source device screen.

A novel display system includes a host and a display. In a particular embodiment the host includes a data scaler and a dual frame buffer. Frames of image data are down-scaled before being transferred to the display, and is up-scaled while being loaded into the frame buffer or the display. The down-scaled frames of image data include less data than the frames of image data. In another embodiment, the process of loading the image data into the display begins before an entire frame of data is loaded into the frame buffer. Increasingly sized portions of the image data, each corresponding to a different color field, are asserted on the display and displayed one at a time. The portions of the frame that were not previously displayed are displayed along with the initial portions of a subsequent frame.

The invention pertains to display method, a computer program for performing the steps of the display method and a display system (1), the display system having for example: at least one display unit (13, 16) arranged to present at least one display image, at least one memory unit (12, 15) comprising information related to for example descriptions of a set of default graphics display objects (W1-W3) and configuration data. The configuration data is arranged to define: at least one transparent display layer (L1-L3), at least one transparent display container (CO0-CO2) associated to the at least one transparent display layer and at least one display mode. Each of said at least one display mode comprising a predetermined selection of one or more of said at least one transparent display container of one or more of said at least one display layer.

Embodiments of the present disclosure include apparatuses and method for a stacked light emitting diode (LED) hologram display. A stacked LED hologram display can include a first array of LEDs that are configured to emit red light received by a meta-optics panel configured to display a first portion of a holographic image, a second array of LEDs that are configured to emit green light received by a meta-optics panel configured to display a second portion of a holographic image, and a third array of LEDs that are configured to emit blue light received by a meta-optics panel configured to display a third portion of a holographic image. The stacked LED hologram display can include a number of actuators configured to adjust a position of a first array of LEDs in first direction and a second direction, adjust a position of a second array of LEDs in the first direction and the second direction, and adjust a position of a third array of LEDs in the first direction and the second direction.

A display device includes a color transformer and an image controller. The color transformer receives and transforms a three-color image into a four-color image. The four-color image includes a red image, a green image, a blue image, and a white image. The image controller calculates decrement offsets of the red image, the green image, and the blue image, and a compensation value of the white image. The image controller calculates gray level values of the red image, the green image, and the blue image when a value of the white image is zero. The image controller respectively calculates a red image control signal, a green image control signal, and a blue image control signal based on the gray level values and the decrement offsets, and the image controller calculates a white image control signal based on the gray level values and the compensation value of the white image.
