Problems solved by technology

The above-mentioned touch screen has a single working mode, and it also works in a short period of time during the waiting time. Working for a long time will easily reduce the quality of some components or cause damage to components, thereby affecting the function, service life and reliability of the touch screen, especially for sound waves, Touch screen products with power energy conversion devices such as infrared are more obvious

Abstract

The invention discloses a multiple working mode method for a touch screen. The invention comprises a normal working mode, and further includes a standby working mode. The normal working mode comprises a plurality of normal work cycles, and the standby working mode comprises a plurality of standby work cycles. The normal work cycles are as follows: a processor receives a processed touch recognition signal, if the touch is existed, and the processor calculates touch coordinates which are sent to a mainframe, thereby returning to a starting stage in the normal work cycles by the processor; the standby work cycles are as follows: the processor receives the processed touch recognition signal, is no touch is existed, and the processor controls the fixed delay, thereby returning to the starting stage in the standby work cycles. The invention provides a plurality of working modes, the normal working mode is entered when detecting touch medium, thereby working in the normal work cycle with a short time; the standby working mode is entered when being idle because no touch medium is detected, thereby working in the standby work cycle with a long time; therefore, the service life and reliability of the touch system are increased.

Description

technical field [0001] The invention relates to a computer touch display technology, in particular to a method for multi-working modes of a touch screen. Background technique [0002] Existing touch screens are mainly divided into resistive touch screens, acoustic wave touch screens, infrared touch screens, capacitive touch screens, electromagnetic touch screens, and the like. Acoustic touch screens generally consist of at least 2 transmitting transducers (or transmitting substrates, guiding stripes), at least 2 receiving transducers (or receiving substrates, guiding stripes), at least 2 sets of transmitting stripes, and at least 2 groups of receiving stripes In the enclosed area, the transducers are regularly arranged on the corners or sides of the screen, and at least 4 groups of reflective stripes are engraved with 45 degrees or 135 degrees on the four sides of the screen, ranging from sparse to dense. The acoustic wave touch screen controller...
