Abstract: An electronic device has a display substrate including a display area, a driver area, and a fan-out area. The fan-out area is divided to a plurality of fan-out regions, and has interconnects configured to access display elements formed on the display area. The driver area is adjacent to the fan-out area and configured to receive a driver chip having a plurality of pads. The interconnects of the fan-out area include a subset of first interconnects. Each first interconnect passes a first fan-out region and a second fan-out region to access a respective display element. A first portion of the subset of first interconnects is formed on the first fan-out region with a first interconnect pitch, and a second portion of the subset of first interconnects is formed on the second fan-out region with a second interconnect pitch different from the first interconnect pitch.

Abstract: An electronic device has a display substrate including a display area, a driver area, and a fan-out area. The fan-out area has interconnects that provide electrical accesses to display elements on the display area. A driver chip is disposed on the driver area and includes a first edge adjacent to the display area, two side edges connected to the first edge, and a plurality of pad groups. Each pad group includes a row of electronic pads that are electrically coupled to a subset of display elements via a subset of interconnects routed on the fan-out area. The pad groups include a first pad group and a second pad group disposed immediately adjacent to the first pad group. A first subset of interconnects cross one of the two side edges, and extend above a gap between rows of the first and second pad groups to reach the first pad group.

Abstract: This application is directed to controlling display power consumption of a display panel by dynamically adjusting the voltage level of the display power supply. The display panel includes a plurality of display pixels, each driven by the display power supply. Video data corresponds to an image frame to be displayed on the display panel and includes a plurality of multibit data items. Each display pixel is associated with a respective multibit data item defining a magnitude of a drive current of the respective display pixel. A first multibit data item is identified in the video data for a first display pixel to be driven to provide a corner luminance level on the image frame. A corner drive voltage is determined among a plurality of drive voltages of the display pixels based on the first multibit data item and applied to adjust the voltage level of the display power supply.

Abstract: A display panel subsystem adaptively employs one of three types of input offset voltage cancellation modes based on an analysis of gray level values of sub-pixels for each row un a frame of image data. The system selects a candidate row within a selected group of rows and applies a first chopper mode to each sub-pixel in the candidate row. Under a row-based mode, the system applies a second chopper mode to each sub-pixel included in a row having gray level values matching the candidate row. Under a per-column row-based mode, the system applies the row-based mode on a per-column basis. Under a sub-pixel-wise mode, for each column, the system changes a chopper mode applied to a sub-pixel in a subsequent row relative to the last state of the chopper mode in a row having the same gray level value as a corresponding sub-pixel in the subsequent row.
