Problems solved by technology
The advantage of infrared touch screen is that it is cheap, and it is not affected by current, voltage and static electricity, and is suitable for harsh environmental conditions. The disadvantage is that the resolution is low, and the thickness of the whole machine is increased due to the increase of the outer frame
The advantage of the capacitive screen is that the writing experience is smooth, the resolution is high, and the whole machine can be made light and thin, but the disadvantage of the capacitive screen is that it is easily disturbed by the external environment and drifts, resulting in inaccurate touch or inability to touch and write
For example, when the ambient temperature and humidity change, it will cause the drift of the capacitive screen, resulting in inaccurate touch

Disclosed in the present invention are a method and device for obtaining touch screen reference data, a storage medium and a touch display system. The method is executed by a system comprising a display screen (101) and a touch screen (103) and specifically comprises: detecting whether the display screen (101) executes a display state change operation; if it is detected that the display screen (101) executes the display state change operation, determining whether the touch screen (103) is in an operating state; and if the touch screen (103) is in the operating state and the display state change operation is completed, obtaining reference data from the touch screen (103), so that a touch signal received by the touch screen (103) is calibrated according to the reference data. By means of embodiments of the present invention, calibration of the touch screen (103) signal is optimized, and the operating stability of the touch display system is improved.
Description
technical field [0001] The invention relates to the technical field of touch screens, in particular to a method, device, storage medium and touch display system for acquiring touch screen reference data. Background technique [0002] Currently commonly used smart panels can be roughly divided into infrared-screen smart panels and capacitive-screen smart panels according to the touch type. Infrared Touch Screen Technology (Infrared Touch Screen Technology) is composed of a touch screen and infrared emitting and receiving sensing elements installed on the outer frame of the touch screen. The infrared emitting and receiving sensing elements form an infrared detection network on the surface of the screen, and any touching object can change the contact point. Touch screen operation is realized by infrared rays on the screen. The capacitive screen uses the current induction of the human body to work. The advantage of the infrared touch screen is that it is cheap, and it is not a...
