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.

Abstract: A device includes a timing test circuit. The timing test circuit receives a timing signal related to the display of an image on a display. The timing test circuit also determines if the timing signals are invalid. Moreover, the timing test circuit transmits a fault indication when the timing signals are determined to be invalid.

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 display such as a liquid crystal display. The display may have a color filter layer and a thin-film transistor (TFT) layer. An active portion of the display may contain an array of display pixels that are controlled by control signals that are provided over intersecting gate lines and data lines. In an inactive portion of the display, display driver circuitry may be used to provide data signals for the data lines. Each display pixel may be coupled to a corresponding gate line, data line, and may share a common electrode. Changes in the data signals may be coupled onto the common electrode to cause voltage rippling. Compensation circuitry may be coupled to the common electrode via an AC or a DC coupling connection to help reduce the voltage rippling.
