Abstract

A touch panel device includes a touch panel and a controller. The touch panel includes a first region and a second region. The first region includes a plurality of first driving conductors extended along a first direction, and a plurality of first sensing conductors extended along a second direction perpendicular to the first direction. The second region includes a plurality of second driving conductors extended along the first direction, and a plurality of second sensing conductors extended along the second direction. The controller is used for outputting a plurality of driving signals in an ordered sequence of the second direction to drive the plurality of first driving conductors and the plurality of second driving conductors, and for receiving a plurality of sensing signals from the plurality of first sensing conductors and the plurality of second sensing conductors in an ordered sequence of the first direction.

Description

Technical field [0001] The invention relates to a touch display device, in particular to a touch display device for driving a large-sized touch panel. Background technique [0002] Advanced displays are one of the main consumer electronics products. Touch panel displays that can be directly touched by users have been widely used in televisions, smart phones and other electronic products due to their portability and convenience. [0003] In order to increase portability and convenience, touch panels that can be directly touched by users have become the focus of market development. A liquid crystal display (LCD) of a smart phone is usually equipped with a touch panel to omit buttons and function keys. The touch panel controls the image display and functions of the liquid crystal display through electronic signals. After the user touches the surface of the touch panel, an electronic signal is generated. [0004] See figure 1 . figure 1 A schematic diagram of a touch display device 1...
