Abstract

The invention relates to the technical field of TP chips, in particular to a TP chip scanning method for improving point reporting accuracy. Each charge amplifier carries out data acquisition on each channel needing acquisition. The TP chip has the advantages that the technical process offset of the charge amplifier and the capacitance mismatch of the channel capacitor are counteracted, and the point reporting accuracy of the TP chip is improved.

Description

technical field [0001] The invention relates to the technical field of TP chips, in particular to a TP chip scanning method for increasing reporting accuracy. Background technique [0002] Capacitive touch screens, such as figure 1 Shown mainly consists of 4 parts. The uppermost layer is a glass cover, and channels on the cover are generally cut out according to the rules, and users can realize human-computer interaction by touching the channels. The second layer is the ITO layer, and the ITO wiring matches the channel pattern and position cut by the glass cover. According to the ITO wiring, the electrodes of each channel are built to form the electrode layer. In the electrode layer, the electrode and the ground form a self-capacitance. When a finger is touched, the capacitance of the human finger will be coupled to the self-capacitance. TPIC determines whether there is a finger touch by continuously detecting the capacitance data of each channel. And determine where the...
