本发明涉及触摸屏技术领域，尤其涉及一种获取触摸屏基准资料的方法、装置、存储介质及触摸显示系统。The present invention relates to the field of touch screen technologies, and in particular, to a method, an apparatus, a storage medium, and a touch display system for acquiring touch screen reference data.
背景技术Background technique
目前常用的智能平板根据触控类型大致可分为红外屏智能平板及电容屏智能平板。红外屏(Infrared Touch Screen Technology)由触摸屏及装在触摸屏外框上的红外线发射与接收感测元件构成，红外线发射与接收感测元件在屏幕表面上形成红外线探测网，任何触摸物体可改变触点上的红外线而实现触摸屏操作。电容屏则是利用人体的电流感应进行工作的。红外触摸屏的优点是价格便宜，且不受电流、电压和静电干扰，适宜恶劣的环境条件，缺点是分辨率低，且由于增加了外框，导致整机厚度的增加。电容屏的优点是书写体验流畅，分辨率高，且能做到整机轻薄，但电容屏的缺点是容易受外界环境的干扰产生漂移，导致触摸不准或无法触摸书写。例如，当环境温度、湿度改变时，都会引起电容屏的漂移，造成触控不准确。电容屏的漂移原因属于技术上的先天不足，环境电势面(包括用户的身体)虽然与电容触摸屏离得较远，却比手指头面积大的多，这些因素都直接影响触摸位置的确定。Currently, the commonly used smart tablets can be roughly classified into an infrared screen smart tablet and a capacitive screen smart tablet according to the type of touch. Infrared Touch Screen Technology consists of a touch screen and infrared transmitting and receiving sensing elements mounted on the outer frame of the touch screen. The infrared emitting and receiving sensing elements form an infrared detecting net on the surface of the screen, and any touch object can change the contact. Touch screen operation is achieved by infrared rays. The capacitive screen works with the current sensing of the human body. The advantage of the infrared touch screen is that it is cheap and free from current, voltage and static interference, 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 thin, but the disadvantage of the capacitive screen is that it is easily disturbed by the interference of the external environment, resulting in inaccurate touch or inability to touch and write. For example, when the ambient temperature and humidity change, it will cause the capacitive screen to drift, resulting in inaccurate touch. The drift of the capacitive screen is a technically insufficiency. The environmental potential surface (including the user's body) is farther away from the capacitive touch screen, but much larger than the finger area. These factors directly affect the determination of the touch position.

S2，当检测所述显示屏执行显示状态更改操作时，判断所述触摸屏是否处于工作状态。S2. When detecting that the display screen performs a display state change operation, determine whether the touch screen is in an active state.
需要说明的是，由于上述机显示屏在执行上述操作时，触摸屏应当也启动工作或处于工作状态，即显示屏的显示状态更改操作所产生地硬件干扰只会同时也处于上电工作状态的触摸屏产生干扰。It should be noted that, since the above-mentioned operation of the above-mentioned machine display screen, the touch screen should also start working or be in a working state, that is, the hardware interference generated by the display state changing operation of the display screen is only in the power-on working state.
