Embodiment Construction

[0026] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.

[0027] Various embodiments of the present invention provide a display device with improved wiring between a connector and a source driver disposed on a substrate such as glass. Various features improve the different characteristics of the wiring between the connector and source driver. For example, t-shaped connectors are provided to ensure that the voltages supplied to the source drivers are substantially equal. Routing may be tapered (ie, varied in width) to reduce the amount of area consumption in locations where this is desired, but reduce resistance in areas with more space. Routing may also include stacked power and groun...

Abstract

A display device with improved wiring between a connector and a source driver arranged on a substrate such as glass. Various features improve the different characteristics of the wiring between the connector and source drivers. For example, t-shaped connectors are provided to ensure that the voltages supplied to the source drivers are substantially equal. The wires may be tapered (ie, vary in width) to reduce area consumption in locations where this is desired, but to reduce resistance in areas with more space. Routing may also include stacked power and ground traces to provide benefits such as improved decoupling capacitance. Other features are provided.

Description

technical field [0001] Embodiments relate generally to display devices, and in particular, to wiring configurations for connectors coupled to source drivers in display devices. Background technique [0002] Input devices including proximity sensor devices (also commonly referred to as touchpads or touch sensor devices) are widely used in a wide variety of electronic systems. Proximity sensor devices typically include a sensing area, often distinguished by a surface, in which the proximity sensor device determines the presence, position and / or motion of one or more input objects. A proximity sensor device may be used to provide an interface to the electronic system. For example, proximity sensor devices are often used as input devices for larger computing systems (such as opaque touchpads integrated in or external to notebook or desktop computers). Proximity sensor devices are also often used in smaller computing systems such as touch screens integrated in cellular telephon...
