TOUCH DISPLAY DEVICE
First Claim
Patent Images
1. A touch display device, comprising:
- a first substrate layer, comprising a plurality of transistors;
a second substrate layer, disposed opposite to the first substrate layer;
a first electrode layer, disposed over the first substrate layer and interposed between the first substrate layer and the second substrate layer;
a second electrode layer, disposed over the second substrate layer and interposed between the first substrate layer and the second substrate layer; and
a controller electrically connected to the first electrode layer, wherein the controller outputs a first signal to the first electrode layer when the touch display device is operated under a display mode and outputs a second signal to the first electrode layer when the touch display device is operated under a touch mode;
wherein when the touch display device is operated under the touch mode, the controller generates a sensing output signal and determines that a touch event occurs when the value of the sensing output signal is greater than a first threshold, the controller further determines that a pressing touch event occurs when the value of the sensing output signal is greater than a second threshold.

Abstract
A touch display device includes a first substrate layer, a second substrate layer, a first electrode layer, a second electrode layer and a controller. The first substrate layer includes a plurality of transistors. The second substrate layer is disposed opposite to the first substrate layer. The first electrode layer is disposed over the first substrate layer and interposed between the first substrate layer and the second substrate layer. The second electrode layer is disposed over the second substrate layer and interposed between the first substrate layer and the second substrate layer. The controller is electrically connected to the first electrode layer.
