Description

technical field [0001] The present application belongs to the technical field of touch display, and in particular relates to a dual-mode touch display device and an implementation method thereof. Background technique [0002] With the development of the touch screen industry, people's demand for high-precision and multi-function touch screens is rising rapidly. In the existing display touch devices, although capacitive touch has high sensitivity, convenient operation and good hand touch experience, its touch speed and resolution are low; while electromagnetic pen touch has extremely high touch speed and resolution, and has a real original handwriting function. Therefore, people are eager to have a capacitive touch and electromagnetic pen dual-mode touch display device, which not only has a convenient hand touch function, but also has a smooth writing function like a real pen. [0003] In order to solve this problem, in the prior art, the capacitive screen, the liquid cryst...
