Abstract: A display driver comprises an interface and signal supply circuitry. The interface is configured to receive image data. The signal supply circuitry is configured to supply at least one drive control signal to a display panel based on a detection of a data error in the image data associated with a first horizontal line in a first vertical sync period, causing a first pixel circuit and a second pixel circuit hold, in the first vertical sync period, first hold voltages based in part on at least one drive control signal and second hold voltages held in a second vertical sync period prior to the first vertical sync period. The first pixel circuit is associated with the first horizontal line, and the second pixel circuit is associated with a second horizontal line and driven after the first pixel circuit.

Abstract: A sensing device comprises sensor electrodes arranged in an array of rows and columns, and vias. A first vias is arranged in a first direction, and corresponds to a first column of sensor electrodes adjacent to a first side edge of the sensing device. A second via is arranged in a second direction different than the first direction, and corresponds to a second column of the sensor electrodes adjacent to a second side edge of the sensing device. Each of the sensor electrodes is configured to be coupled to a routing trace through one of the vias. In a first row of the plurality of sensor electrodes, a two vias are different distances from the first side edge and in a second row of the plurality of sensor electrodes, two vias are different distances from the second side edge.
