TOUCH SCREEN BORDER REGIONS

摘要

Touch screens with more compact border regions can include an active area that includes touch sensing circuitry including drive lines, and a border region around the active area. The border region can include an area of sealant deposited on conductive lines, and transistor circuitry, such as gate drivers, between the active area and the sealant. The conductive lines can extend from the sealant to the active area without electrically connecting to the transistor circuitry. The conductive lines can have equal impedances and can connect the drive lines to a touch controller off of the touch screen. A set of drive signal characteristics for the drive lines can be obtained by determining a transfer function associated with each drive line, obtaining an inverse of each transfer function, and applying a set of individual sense signal characteristics to the inverse transfer functions to obtain the corresponding set of drive signal characteristics.

1. A touch screen including an active area, the active area including a plurality of display pixels and touch sensing circuitry, the touch screen comprising:
a plurality of gate drivers disposed in a first region adjacent to the active area, the gate drivers driving at least some of the display pixels; and conductive lines connected to the touch sensing circuitry in the active area, each conductive line extending from the active area, and portions of the conductive lines formed at a gap between an adjacent pair of gate drivers.
