Examples of the present disclosure are related to systems and methods for operating display devices with dual pathway connections. More particularly, embodiments disclose electronic signage devices with dual or redundant pathways offering lower cost and higher reliability.

Methods and systems may provide for identifying a plurality of subject commands that reference a common screen location and access a read/write resource, and serializing the plurality of subject commands according to a predefined order. Additionally, execution of the plurality of subject commands may be deferred until one or more additional commands referencing the common screen location are executed. In one example, the plurality of subject commands are serialized in response to a serialization command.

A method of connecting a mobile device to a common display associated with a display computer controlling the common display, including, for each mobile device downloading a display application onto the mobile device, selecting the display computer for the common display in the display application, connecting the mobile device to the display computer, selecting, on the mobile device, what is to be displayed on the common display, and sending a data stream of the selection to the display computer to be displayed in a window on the common display corresponding to the mobile device.

A system, computer readable medium, and method for sub-frame scan-out are disclosed. The method includes the steps of dividing a frame into a plurality of slices. For each slice in the plurality of slices, the steps further include sampling a sensor associated with a head mounted display to generate sample data corresponding to the slice; adjusting one or more parameters associated with rendering operations for the slice based on the sample data; and rendering primitive data associated with a model according to the rendering operations to generate image data for the slice. Each slice is a portion of the frame and corresponds to different sample data from the sensor. Thus, adjusting of the parameters is different for each slice of the frame.

A method for displaying pixels on display devices, comprising the steps of (a) Providing virtual pixel storage means, preferably one or more virtual frame buffers (6), for temporarily storing the pixel data, (b) Receiving pixel data into the virtual pixel storage means (6) from one or more pixel sources (5), (c) Processing the pixel data stored in the virtual pixel storage means, based on characteristic display parameters characterizing the display devices; and (d) Transmitting the pixel data from the virtual pixel storage means (6) to one or more virtual displays attached to the virtual pixel storage means via a network (7), based on a network transmission protocol. The invention further relates to a system for displaying pixels on display devices.

Disclosed are an electronic device and a method for controlling the electronic device. Specifically, the electronic device according to the present disclosure receives a first image signal and a second image signal which are separated from an original image signal through a first channel and a second channel having different frequency bandwidths, and which have different data rates. When the first image signal and the second image signal are received, the electronic device determines whether an error exists in the second image signal, obtains a first output image signal and a second output image signal on the basis of the first image signal and the second image signal according to a result of the determination, and outputs the obtained first output image signal or second output image signal.

A display control method includes: in response to a display area of a display device being divided into multiple display sub-areas, controlling outputs from the multiple display sub-areas at corresponding refresh rates. The refresh rates of different display sub-areas can be the same or different.

A source driver is provided, including a first data receiving part that receives a serial data signal via the first transmission line, a selector that outputs a serial data signal from either the first transmission line or the second transmission line according to a switching signal, a second data receiving part that receives the serial data signal output from the selector, a first serial-parallel conversion circuit that serial-parallel converts the serial data signal received by the first data receiving part and outputs the converted signal as first parallel data, a second serial-parallel conversion circuit that serial-parallel converts the serial data signal received by the second data receiving part and outputs the converted signal as second parallel data, and a comparison circuit that compares the first parallel data with the second parallel data and outputs a comparison result when the selector outputs the serial data signal from the first transmission line.
