The invention discloses a scribing detection system and method based on a USB interface capacitive touch screen. The scribing detection system comprises a touch panel and a main control device which are mutually connected, wherein the main control device comprises a touch panel control module which calls a touch drive module of the main control device to communicate with the touch panel through a USB. With the adoption of the scribing detection system and method based on the USB interface capacitive touch screen, the system cost can be significantly reduced, the system compatibility is high, different test requirements can be met, and the detection system can be put into use quickly only through parameter configuration when switching detection touch panel types due to capturing of touch point data from a USB interface and an edible function of the test process.
Description
technical field [0001] The invention belongs to the field of capacitive touch screen detection, and more specifically relates to a scribing detection system and detection method based on a USB interface capacitive touch screen. Background technique [0002] As touchable electronic devices represented by mobile phones and tablet computers become more and more widely used in daily life, the market demand for capacitive touch screens becomes larger and larger. Different from the traditional ordinary liquid crystal screen detection system and methods which are becoming more and more stable and mature, the capacitive touch screen detection system and detection method are still on the way of exploration. Many touch screen integrated chip manufacturers provide their own standard interfaces, which makes the development of the touch screen detection system difficult, high system cost, long time cycle, and poor compatibility. Contents of the invention [0003] Aiming at the above d...
