Abstract: An electronic display includes an active area including multiple pixels. The electronic display also includes a first row driver set including a first column of row drivers and a second column of row drivers. A first active row driver in the first column of row drivers drives a first portion of the multiple pixels, and a first spare row driver in the second column of row drivers is in an inactive state. The electronic display also includes a second row driver set including a third column of row drivers and a fourth column of row drivers. A third active row driver in the third column of row drivers drives a second portion of the multiple pixels, and a second spare row driver in the fourth column of row drivers is inactive.

Abstract: A display may include an array of pixels covered by lenticular lenses. The lenticular lenses may cause expansion of light primarily in a horizontal direction. To improve the perceived resolution of the display, the horizontal resolution of the pixels on the display may be increased. In one possible layout, each pixel includes one red sub-pixel, one blue sub-pixel, and one green sub-pixel. The sub-pixels may be non-square rectangular. The sub-pixels may be the same size or may have the same widths and different heights. Each pixel may be asymmetric about a horizontal axis. In a given row, the pixels may alternate between first and second layouts. The second layout may be a vertically flipped version of the first layout.

Abstract: An electronic device may include a display. The display includes display driver circuitry for driving data lines routed across the display. The electronic device may have a recessed device housing region, where at least some of the data lines are routed around the recessed region. The data lines being routed around the recessed region may be formed in at least two different metal routing layers. The electronic device may further include additional display driver circuitry for driving data lines from another peripheral housing edge to obviate the need to route around the recessed region. The data lines from the two display driver circuitries can be disconnected at random locations or can be interlaced to achieve spatial interleaving. The display driver circuitry may include demultiplexing circuitry having smaller switches coupled in parallel with larger demultiplexer routing switches to reduce voltage kick and charge injection.

Abstract: Hybrid architectures and method methods of operating a display panel are described. In an embodiment, row driver and pixel driver functions are combined in a group of backbone hybrid pixel driver chips, wherein global signal lines are distributed to the backbone hybrid pixel driver chips, where the global signals are manipulated and distributed to a row of pixel driver chips.

Abstract: An electronic device may include a display, a display driver integrated circuit for controlling the display, and a system processor for running one or more applications on the electronic device. The display may be operated in at least a video mode and a command mode. In the video mode, the system processor operates as the primary timing circuit while the display driver integrated circuit operates as the secondary timing circuit. In the command mode, the display driver integrate circuit operates as the primary timing circuit while the system processor operates as the secondary timing circuit. The system processor may be configured to switch between video mode and the command mode without turning off the electronic device and without turning off the display driver integrated circuit. If desired, the display can be temporarily turned off during a mode switching event to hide potential front of screen artifacts.

Abstract: Systems and methods for electronic displays to use reference voltages to control driving current of illuminators are provided. The reference voltages are used to reduce or eliminate cross talk in driving voltages among different illuminators and driving voltage variations from frame to frame. The transient performance of the driving current of the illuminator (e.g., the current rise/decline time, current overshoot issue, current settling time) may be improved by implementing the reference voltages.
