Abstract:
A pressure sensing input equipment includes a first electrode layer, a second electrode layer, a first substrate, and a pressure sensing chip. The first substrate is disposed between the first electrode layer and the second electrode layer. The first electrode layer includes first pressure sensing electrodes and first axial touch sensing electrodes. The first pressure sensing electrodes and the first axial touch sensing electrodes are alternately arranged and insulated from each other and do not overlap. The first pressure sensing electrodes are applied for detecting pressure magnitude. The first pressure sensing electrodes include a first end part and a second end part. The pressure sensing chip is electrically connected to the pressure sensing electrodes, and the pressure sensing chip determines the pressure magnitude by detecting, the resistance variation of the pressure sensing electrodes after pressured. With such design, the pressure sensing input equipment can achieve better pressure magnitude detection.
