Touch sensitive input devices and routing trace configurations designed to reduce border dimensions of such devices are provided herein. The touch sensitive input devices include a touch panel having a plurality of transmit lines and a plurality of receive lines, which are arranged with the plurality of transmit lines in a grid pattern, such that a sense node is disposed on the touch panel at each intersection of the transmit and receive lines. More specifically, the touch panel includes a first subset of the transmit lines coupled to routing traces on only a first side of the touch panel, a second subset of the transmit lines coupled to routing traces on only a second side of the touch panel, and a third subset of the transmit lines coupled to routing traces on both the first side and the second side of the touch panel. Methods are provided herein for compensating for differences in routing trace path lengths, so as to provide accurate detection of touch event locations on the touch panel.

A display presents information with pixels driven at overdrive voltages set based upon a user configuration and sensed environmental conditions. Varied overdrive voltages provide adaptable display responses with proportional power consumption so that power consumption is reduced where visual images of a display content have reduced need for rapid display response. For example, reduced bandwidth availability that impacts display resolution allows reduced overdrive voltages that scale to visual content resolution.

Methods and systems to regenerate H-sync by a touch controller are described. In an embodiment, a method may include setting, using a processing device, a noise peak threshold for identifying a Horizontal Synchronization (H-Sync) signal generated by a display device. The method may also include determining, using the processing device, a frequency of the noise peaks that exceed the noise peak threshold. Additionally, the method may include selecting, using the processing device, an H-sync signal for regeneration by referencing a lookup table of H-sync signals with reference to the determined frequency of the noise peaks that exceed the noise peak threshold.

A portable information handling system keyboard rests on a support surface of a housing with securing actions taken from above the housing, such as by screws that insert through the keyboard and then into the housing. A lattice cover having key openings fits over the keyboard to align adapters of its bottom surface with posts extending from the support surface through openings formed in the keyboard. The adapters snap to the posts to couple the cover against the keyboard so that the cover bottom surface presses the keyboard against the information handling systems upper support surface.
