Embodiment Construction
[0024] The touch display device provided by the present invention can be used as a display terminal with a touch interaction form such as a mobile phone and a tablet computer.
[0025] Such as figure 1 As shown, the touch display device includes a protective cover 10 , a touch sensing unit 20 , a display unit and a pressure sensing unit 70 .
[0026] The touch sensing unit 20 includes touch driving electrodes and touch sensing electrodes. The touch driving electrodes and the touch sensing electrodes can be distributed on the same substrate, such as the so-called GF structure, GF2 structure, etc. in the industry, or respectively distributed on two different substrates, such as the GFF structure called in the industry. In some other embodiments, the touch driving electrodes and the touch sensing electrodes may also be formed on the lower surface of the protective cover 10 so that the protective cover 10 also functions as a capacitive sensor. This structure is called an OGS stru...
