The disclosure discloses a method and device for identifying a type of a resistive touch screen. The method includes: controlling the level of a signal line in the first direction and the level of a signal line in the second direction to be different levels in the pull-up level and the pull-down level, and the level of the middle signal line is the pull-up level. flat or pull-down level, the signal lines in the two directions are respectively connected to electrodes in different directions in the touch screen, the intermediate signal line is connected to the intermediate electrode, and the signal lines and intermediate signals in the first direction and the second direction are detected The level change of the line, and the type of the touch screen is identified according to the level change. The above method and device for identifying the type of resistive touch screen can control the levels of different electrodes in the touch screen, and automatically identify the type of the touch screen according to the level change.
Description
technical field [0001] The present disclosure relates to the technical field of touch screen identification, in particular to an identification method and device for four-wire and five-wire resistive touch screens. Background technique [0002] In various electronic devices, resistive touch screens are widely used for convenient operation. Among resistive touch screens, four-wire resistive touch screens and five-wire resistive touch screens are most commonly used. [0003] At present, in various electronic devices, only one type of resistive touch screen is often used, that is, a four-wire resistive touch screen or a five-wire resistive touch screen. However, there are many suppliers of touch screens, and their prices change frequently. Due to its own cost, switching between four-wire resistive touch screens and five-wire resistive touch screens often occurs. [0004] However, the hardware circuits of various electronic devices are often only equipped with a detection circ...
