Touch screen liquid crystal display
Steven Porter Hotelling,Wei Chen,Christoph Horst Krah,John Greer Elias,Wei Hsin Yao,John Z. Zhong,Andrew Hodge,Brian R. Land,Willem den Boer +8 more
TL;DR: In this paper, liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry are discussed. But the integration may take a variety of forms.
Patent
Touch sensitive displays
TL;DR: In this article, a touch sensor is formed from electrodes (44) located on a thin-film encapsulation layer (84) or one or more sides of a polarizer, which can be attached to the upper or lower surface of the polarizer.
Patent
Displays with bent signal lines
TL;DR: A display may be provided with an active central region and a peripheral inactive region as discussed by the authors, where conductive lines may pass between components in the active central regions such as display pixels and touch sensor electrodes and components in a peripheral peripheral region such as gate driver circuitry and patterned interconnect lines.
Patent
Integrated display and touch screen
Steve Porter Hotelling,Wei Chen,Christoph Horst Krah,John Greer Elias,Wei Hsin Yao,John Z. Zhong,Andrew Hodge,Brian R. Land,Willem den Boer +8 more
TL;DR: In this article, a method of operating the integrated touch sensing elements with the display circuitry includes dividing touch-sensing circuitry of the touch screen into a plurality of drive segments, each drive segment overlapping one or more display rows.
Patent
Display brightness control temporal response
TL;DR: In this article, the response rates for changing brightness levels based on ambient light levels are designed to approximate the physical response of the human vision system and noise reduction techniques are employed by adjusting the response rate based on the magnitude of the change in the ambient light level and/or based on whether the display is operating at steady state or executing a brightness adjustment.
