Techniques are provided for improving electronic display startup time using extended display identification data (EDID) shadowing. In one example, a method for starting an electronic display may include accessing, by a timing controller, EDID from a memory device. The method may also include storing EDID from the memory device in the timing controller. The method may include, after storing EDID from the memory device, transmitting a signal from the timing controller to a host device to indicate that the host device can access the stored EDID. The method may also include accessing, by the timing controller, configuration data from the memory device. The method may include, after transmitting the signal to the host device, transferring the EDID stored in the timing controller to the host device while the timing controller is accessing the configuration data resulting in reduced startup time of the electronic display.

A method for reducing power consumption of an electronic display is provided. In one embodiment, the method includes transmitting data packets over a data channel between a timing controller and a column driver of the display. Data transmission modes may be read from headers of the data packets, and image data of the packets may be processed at the column driver based on their respective data transmission modes. Further, the data channel may be intermittently deactivated during transmission of the data packets based on their respective data transmission modes. Additional methods, systems, and devices relating to electronic displays are also disclosed.

Systems and methods are provided for reducing motion blur in a video display. A system for reducing motion blur in a video display may include a motion detection circuit and a luminance control circuit. The motion detection circuit may be used to compare a plurality of frames in a video signal to generate a motion detection output signal that indicates whether the video signal includes an image that is in motion or a still image. The luminance control circuit may be used to vary luminance levels between two or more consecutive frames of the video signal when the motion detection output signal indicates that the video signal includes an image that is in motion. The luminance control circuit further may also be used to discontinue varying the luminance levels of the video signal when the motion detection output signal indicates that the video signal includes a still image.

An Internet access time control method using an authentication assertion is provided. In the method, a user ID is registered in an asserting party site in a single sign-on (SSO) environment by using a user terminal. The asserting party site manages user IDs for providing an SSO service. Control setup values are set in the asserting party site by using the user terminal. Here, the control setup values include an Internet usage duration and an Internet access-restricted time band for the user. A service time of a relying party site accessed by the user terminal is controlled according to an authentication assertion containing the control setup values. Accordingly, the method makes it possible not only to control Internet usage time, but also to prevent the child from unreasonably using the Internet.
