Abstract: An electronic display pipeline may process image data for display on an electronic display. The electronic display pipeline may include burn-in compensation statistics collection circuitry and burn-in compensation circuitry. The burn-in compensation statistics collection circuitry may collect image statistics based at least in part on the image data. The statistics may estimate a likely amount of non-uniform aging of the sub-pixels of the electronic display. The burn-in compensation circuitry may apply a gain to sub-pixels of the image data to account for non-uniform aging of corresponding sub-pixels of the electronic display. The applied gain may be based at least in part on the image statistics collected by the burn-in compensation statistics collection circuitry.

Abstract: Systems, apparatuses, and methods for performing mid-frame blanking. A first portion of a frame is driven to a display and then a first mid-frame blanking interval is generated. Following this first mid-frame blanking interval, a second portion of the frame is driven to the display, followed by a second mid-frame blanking interval, followed by a third portion of the frame, and so on. Any number of mid-frame blanking intervals may be introduced in a given frame. During each mid-frame blanking interval, touch sensing is performed to detect touch events on the screen for in-cell touch type displays. For displays with touch sensors electrically separated from the display common voltage layer, special sense scan steps are performed during mid-frame blanking intervals. By performing touch sensing or special sense scan steps during a frame rather than only at the end of a frame, the performance of touch sensing is improved.

Abstract translation: 用于执行中间帧消隐的系统，装置和方法。 帧的第一部分被驱动到显示器，然后产生第一中间帧消隐间隔。 在该第一中间帧消隐间隔之后，该帧的第二部分被驱动到显示器，之后是第二中间帧消隐间隔，接着是该帧的第三部分，以此类推。 在给定的帧中可以引入任何数量的中间帧消隐间隔。 在每个中间帧消隐期间，执行触摸感应以检测屏幕上的内嵌触摸型显示器的触摸事件。 对于与显示公共电压层电气分离的具有触摸传感器的显示器，在中间帧消隐间隔期间执行特殊感测扫描步骤。 通过在一帧期间执行触摸感测或特殊感测扫描步骤而不是仅在帧的末尾，触摸感测的性能得到改善。
