Abstract: An electronic device has a display screen and a driver chip disposed on a driver area of the display screen. A fan-out area of the display screen has interconnects configured to provide electrical accesses to display elements of the display area. The driver chip includes a first edge, a second edge, and a row of electronic pads proximate to the first edge. The electronic pads have a first subset of end pads at a first end of the first row, a second subset of end pads at a second opposite end of the first row, and a subset of intermediate pads located between the first subset and second subset of end pads. The first subset of end pads physically contact a first subset of interconnects from the first edge, and the subset of intermediate pads physically contact a second subset of interconnects from the one or more second edges.

Abstract: This application is directed to intra-panel communication in a touch display device in which a touch-integrated timing controller (TTCON) is coupled to touch-embedded source drivers (TSDs) via a plurality of forward links and a set of backward links. The forward links include a first subset of display forward links and a second subset of touch forward links. The TSDs are electrically coupled to a display panel including a plurality of display pixels and a plurality of touch sensors. The TTCON sends a display drive signal including display content data and display control data over the display forward links, and sends a touch control signal including an instruction to initiate an operation mode over the touch forward links. Upon receiving the touch control signal, the TSDs identify the instruction to initiate the operation mode, generate touch data accordingly, and return the touch data to the TTCON via the backward links.
