The interface unit receives the image data including display image data and error detection data that includes at least position information regarding an error detection region, and the error detection unit performs the error detection on the display image data based on the display image data of the error detection region that is specified by the position information.

Method, device and system for access control for wireless streaming of audio-visual data to a receiver device, it comprising the steps of: wirelessly connecting the receiver device to a plurality of sender devices positioned in an area, transmitting, by the receiver device, a privilege signal pertaining to a sender device to obtain a privileged status, the privilege signal having spatial coverage within the area, extracting, by at least one of sender devices, privilege credentials from the privilege signal, and transmitting the privilege credentials from the at least one sender device to the receiver device to acquire privileged status, controlling, by a sender device having a privilege status, access of wireless data streaming from any other sender devices to the receiver device. The method, device and system can be advantageous as it differentiates users and permits privileged sender device to control wireless streaming of audio-visual data from other sender devices to the receiver device.

Systems, methods, and computer-readable media are disclosed for controlling parameters of a holographic image. A gaze direction of a user is detected and user interaction data indicative of the gaze direction of the user is generated. A determination is then made using the user interaction data that the gaze direction of the user at least partially coincides with an object of interest. A further determination is made that the object of interest is at least partially obscured by the holographic image. One or more of the parameters of the holographic image are then adjusted to enhance visibility of the object of interest to the user.

A display device is used in conjunction with: (1) optical sensors to collect information about ambient conditions in the environment of a viewer of the display device; and/or (2) privacy element identification and detection mechanisms (PEDMs) to collect information about the presence, orientation, and/or type of privacy elements being used in conjunction with the display device. For one embodiment, a processor in communication with the display device may create a view model based, at least in part, on the predicted effects of the ambient environmental conditions and/or presence of privacy elements being used in conjunction with the display device on the user's viewing experience. The view model may be a function of gamma, black point, white point, privacy element orientation and/or type, backlighting, field of view, number of viewers, color offset, or a combination thereof. The view model is also referred to as an ambient/privacy model.

Example implementations relate to an electrophoretic display (EPD) device with anti-reflective nanoparticles. For example, a display device may include a display panel to display content and an EPD device adjacent to the display panel. The EPD device provides a voltage to at least a portion of the EPD device such that positively-charged anti-reflective nanoparticles in the EPD device are moved toward a negative voltage and negatively-charged anti-reflective nanoparticles in the EPD device are moved toward a positive voltage. The content is displayed based on locations of the positively-charged anti-reflective nanoparticles and the negatively-charged anti-reflective nanoparticles in response to the voltage.

The present invention provides a viewing angle mode switching method of a liquid crystal display device and the liquid crystal display device. A viewing angle mode switching request is received. The target view mode is a first viewing angle mode or a second viewing angle mode. A timing relationship between the second scanning signal and the first scanning signal is adjusted, according to the viewing angle mode switching request. The liquid crystal display device is instructed to switch between the first viewing angle mode and the second viewing angle mode, according to a change of the timing relationship between the second scanning signal and the first scanning signal. With implementing the embodiments of the present invention, switch between different viewing modes can be achieved, and the display convenience of the liquid crystal display device can be improved.
