  • Patent number: 10133120
    Abstract: Techniques for driving a dual modulation display include generating backlight drive signals to drive individually-controllable illumination sources. The illumination sources emit first light onto a light conversion layer. The light conversion layer converts the first light, such as blue or ultraviolet light, into second light, such as white light. The light conversion layer can include quantum dot materials. Liquid crystal display (LCD) modulation drive signals are generated to determine transmission of the second light through individual color subpixels of the display. These LCD modulation drive signals can be adjusted based on one or more light field simulations to account for non-uniform, spatial color shifts. Alternatively, one or more light field simulations based on a uniformity assumption determine intermediate LCD modulation drive signals. A compensation field simulation, using backlight drive signals, is then used to adjust the intermediate LCD modulation drive signal for color correction.

  • Patent number: 10089931
    Abstract: An electronic device that includes a display is provided. The display may have a brightness that is controlled using a series of cascaded digital-to-analog converter circuits. The display may be calibrated at a series of predetermined display brightness settings. For display brightness settings that fall between two consecutive display brightness settings in the series of predetermined display brightness settings, voltage interpolation operations may be performed to obtain the corresponding display brightness settings. Performing voltage interpolations instead of digital brightness setting interpolation helps minimize luminance jumps and unexpected color shifts when adjusting the brightness of the display.

  • Patent number: 10083808
    Abstract: A luminous keyboard with a gaming function includes a gaming program, plural keys, plural light-emitting elements and a control unit. When one of the plural keys is pressed down, a corresponding pressing signal is generated. When one of the plural light-emitting elements is turned on to emit a light beam, the corresponding key is illuminated. The control unit is connected with the plural keys, the plural light-emitting elements and the gaming program. The control unit turns on or turns off the plural light-emitting elements according to settings of the gaming program. Alternatively, the control unit turns off the light-emitting element corresponding to the illuminated key when the control unit receives the pressing signal corresponding to the illuminated key. In such way, the luminous keyboard can be used to play a game.

  • Patent number: 10083662
    Abstract: The invention provides a data processing method for transparent LCD; which computes the color saturation of each display pixel based on the grayscale values of the red, green and blue sub-pixels of each display pixel, and selects corresponding equation to compute the grayscale value of the transparent sub-pixel based on the color saturation. When in low color saturation, the invention increases the transmittance of the transparent sub-pixel; when in high color saturation, the invention lowers the transmittance of the transparent sub-pixel; and when the color saturation is in the middle range, the invention balances the transmittance of the transparent sub-pixel. As such, the invention realizes the real time adjustment of the transmittance of the transparent sub-pixel of the transparent LCD and improves the display effect of the transparent LCD.

    Abstract: An invention is disclosed for a real time video analytic processor that embodies algorithms and processing architectures that process a wide variety of sensor images in a fashion that emulates how the human visual path processes and interprets image content. spatial, temporal, and color content of images are analyzed and the salient features of the images determined. These salient features are then compared to the salient features of objects of user interest in order to detect, track, classify, and characterize the activities of the objects. Objects or activities of interest are annotated in the image streams and alerts of critical events are provided to users. Instantiation of the cognitive processing can be accomplished on multi-FPGA and multi-GPU processing hardwares.

  • Patent number: 10074182
    Abstract: Architecture that enables the drawing of markup in a scene that neither obscures the scene nor is undesirably obscured by the scene. When drawing markup such as text, lines, and other graphics, into the scene, a determination is made as to the utility to the viewer of drawing the markup with greater prominence than an occluding scene object. The utility of the markup is based on the distance of the scene object and markup from the camera. Thus, if an object that appears small in the scene and is in front of the markup, the markup will be drawn more clearly, whereas if the same object appears large in the scene and is in front of the markup, the markup is rendered faint, if drawn at all.
