The audio-visual device may include a display, a speaker, and a processor configured to control the audio-visual system to operate in a first mode for outputting media art content while the display is stored in the housing according to a first event, operate in a second mode for outputting audio content through the speaker while part of the display is exposed through the open upper end according to a second event, and operate in a third mode for outputting a visual content while the entire display is exposed through the open upper end according to a third event.

A display device is disclosed. The display device includes a display panel, a rear case positioned in a rear of the display panel, and of which a back surface is exposed to the outside, a backlight unit positioned between the display panel and the rear case and providing the display panel with light, a plurality of ribs extended from a front surface of the rear case and contacting at least a portion of the backlight unit, a boss forwardly extended from the front surface of the rear case, and a controller positioned between the backlight unit and the rear case and coupled with the boss.

The present invention is a display apparatus including a housing, a display member, a support member that supports the display member, a driving unit, and a transmission member that is moved along a side surface of the housing by driving of the driving unit and transmits driving force of the driving unit to the support member, wherein the support member moves the display member into and out of the housing by moving of the transmission member, the support member includes a rotation axis, a first fulcrum that is located a first distance away from the rotation axis, and a second fulcrum that is located a second distance away from the rotation axis, the second distance being greater than the first distance, and the transmission member moves either one of the first fulcrum and the second fulcrum and then moves the other of the first fulcrum and the second fulcrum.

A display apparatus and display method thereof is provided. The display apparatus comprises a display configured to display an image, an image sensor configured to be disposed at a rear side of the display, a reflection member configured to reflect light incident on a front side of the display apparatus and to form an image on the image sensor, and a processor configured to control an operation of the display apparatus based on an image captured in the image sensor.

The invention provides an audio-video conversion device, relating to the field of TV, through converting the LVDS and/or V-by-One input port in the display into an HDMI port to make the display match the widely used HDMI audio-video processing device, so as to improve the flexibility of its adaptation; meanwhile, because the audio-video conversion device directly convert the TV signal in HDMI format into TV signal in LVDS and/or V-by-One format and then send it to the play device for playing, therefore there is no need to provide traditional LVDS chip and/or V-by-One chip on the display panel, and supports relatively high frequency to match frequency division and the frequency conversion of the screen, and then achieve the best image quality.

A computer-implemented method includes receiving a video frame. The computer-implemented method further includes dividing the video frame into two or more frame regions, each of the two or more frame regions corresponding to a selectively coolable region of a display. The computer-implemented method further includes identifying one or more frame characteristics for each of the two or more frame regions. The computer-implemented method further includes determining a cooling intensity to be applied to each selectively coolable region for displaying the video frame on the display based on the one or more frame characteristics. The computer-implemented method further includes applying the cooling intensity to each selectively coolable region at an effective time before displaying the video frame on the display. A corresponding computer system and computer program product are also disclosed.

A projection system for projecting an image with an increased apparent resolution is provided. The projection system includes one or more projectors, a resampler module and a deconvolution module. The resampler module is configured to upsample an incoming high-resolution signal, perform an integer shift operation on a signal, and downsample to two or more low-resolution signals. The deconvolution module is configured to filter the upsampled high-resolution signal using a spatial domain deconvolution operation, the spatial domain deconvolution operation approximating frequency domain optical corrections based on characteristics of the one or more projectors. Preferably, the spatial domain deconvolution operation uses an NN spatial kernel extracted from a spatial domain approximation of a Wiener filter.
