    Abstract: Systems, apparatuses, and methods for driving a split display with multiple display pipelines. Frames for driving a display are logically divided into portions, a first display pipeline drives a first portion of the display, and a second display pipeline drives a second portion of the display. To ensure synchronization between the two display pipelines, a repeat vertical blanking interval (VBI) signal is generated if either of the display pipelines has not already received the frame packet with configuration data for the next frame. When the repeat VBI signal is generated, both display pipelines will repeat processing of the current frame.

    Abstract translation: 用多个显示管道驱动分割显示的系统,设备和方法。 用于驱动显示器的框架被逻辑地分为多个部分,第一显示管道驱动显示器的第一部分,第二显示管线驱动显示器的第二部分。 为了确保两个显示管道之间的同步,如果显示管道中的任一个还没有接收到具有下一帧的配置数据的帧分组,则生成重复垂直消隐间隔(VBI)信号。 当产生重复VBI信号时,两条显示管道将重复对当前帧的处理。

    Abstract: In an embodiment, a display pipe is configured to composite one or more frames of images and/or video sequences to generate output frames for display. Additionally, the display pipe may be configured to compress an output frame and write the compressed frame to memory responsive to detecting static content in the output frames. The display pipe may also be configured to read the compressed frame from memory for display instead of reading the frames for compositing and display. In some embodiments, the display pipe may include an idle screen detect circuit configured to monitor the operation of the display pipe and/or the output frames to detect the static content.

    Abstract: An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The image frames may be displayed with positive and negative polarities to help reduce charge accumulation effects. A charge accumulation tracker may analyze the image frames to determine when there is a risk of excess charge accumulation. The charge accumulation tracker may analyze information on gray levels, frame duration, and frame polarity. The charge accumulation tracker may compute a charge accumulation metric for entire image frames or may process subregions of each frame separately. When subregions are processed separately, each subregion may be individually monitored for a risk of excess charge accumulation.

    Abstract: Embodiments of an apparatus for implementing a display port interface are disclosed. The apparatus may include a source processor and a sink processor coupled through an interface. The interface may include a primary link, an auxiliary link, and a hot plug detect link. The source processor may be operable to send a wake-up command to the sink processor via the auxiliary link. The source processor may send initialization parameters to the sink processor via the primary link. The initialization parameters may include a clock data recovery lock parameter and an idle parameter. Following the initialization parameters, the source processor may send a synchronization signal to the sink processor via the primary link. The source processor may then send a sleep command via the primary link to the sink processor.
