Abstract

The embodiment of the invention provides a method and device for detecting a resistive touch screen. The method comprises the following steps: sampling a pressed area of the resistive touch screen; storing sampling numerical values of all sampling points, obtained through sampling, into a buffer queue; and if the number of the sampling numerical values in the buffer queue reaches a first set number, reporting to an application layer according to difference values among all the sampling numerical values in the buffer queue. According to the method and device for detecting the resistive touch screen, provided by the embodiment of the invention, the sampling numerical values of the sampling points are stored into the buffer queue, and all the sampling numerical values in the buffer queue areprocessed and reported when the number of the sampling numerical values in the buffer queue reaches a certain number, so that effective sampling numerical values are prevented from being filtered outand the sensitivity of the resistive touch screen is improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a detection method and a detection device of a resistive touch screen. Background technique [0002] Currently, touch screens are mainly divided into resistive touch screens and capacitive touch screens. The resistive touch screen is controlled by pressure sensing, and the voltage value of the pressed point on the touch screen is converted into a coordinate value in a rectangular area. The resistive touch screen has high sensitivity and relatively cheap price, and has been widely used in the electronic field. [0003] In the existing resistive touch screen, several sampling points are first stored, and each time a sampling point is collected, it is compared with the stored sampling point, and the sampling point with a large difference between the subsequent sampling point and the stored sampling point is filtered out. The sampling point whose difference between the reporte...
