    IPC: G09G3/20

    Abstract: In an embodiment, an electronic device includes an electronic display. The electronic display provides a programmable latency period in response to receiving a first image frame corresponding to first image frame data. The electronic display also displays the first image frame after the programmable latency period and during display of the first image frame, receives a second image frame corresponding to second image frame data. The electronic display also repeats display of the first image frame in response to receiving the second image frame.

    Abstract: The disclosure describes procedures for dynamically employing a variable refresh rate at an LCD display of a consumer electronic device, such as a laptop computer, a tablet computer, a mobile phone, or a music player device. In some configurations, the consumer electronic device can include a host system portion, having one or more processors and a display system portion, having a timing controller, a buffer circuit, a display driver, and a display panel. The display system can receive image data and image control data from a GPU of the host system, evaluate the received image control data to determine a reduced refresh rate (RRR) for employing at the display panel, and then transition to the RRR, whenever practicable, to conserve power. In some scenarios, the transition to the RRR can be a transition from a LRR of 50 hertz or above to a RRR of 40 hertz or below.

    Abstract: An electronic device may have a housing with a lid that rotates relative to a base. A display in the lid may have a thin-film transistor layer. Display driver circuitry may be mounted to the thin-film transistor layer. A display timing controller integrated circuit may be mounted in the base. A rigid flex printed circuit may have a rigid portion in the base to which the display timing controller integrated circuit is mounted and may have a rigid portion in the lid. A flexible printed circuit portion of the rigid flex printed circuit may be used to couple the rigid printed circuit portion in the lid to the thin-film transistor layer. A flexible printed circuit portion of the rigid flex printed circuit that extends between the lid and the base may be formed from a double-shield-layer single-signal-line-layer flexible printed circuit.
