The shielding of cell phone jammer can be completed in 30s.
When the capacitive touch panel in principle to the human body as an electrode of a capacitor element to use when the conductor near the interlayer coupling between the ITO face a sufficient amount of value capacitors, the current flow away is enough to cause malfunction of the capacitive screen . We know that the capacitance value is inversely proportional to the distances between, but is proportional to the relative area, and also the medium of insulation coefficient. Therefore, when a larger area of the palm of your hand or hand-held conductor material close to the capacitive screen instead of touch can cause malfunction of the capacitive screen, this situation is particularly severe in wet weather, hand on your monitor, the palm of your hand near the display of 7 cm within the body near the monitor less than 15 cm will be able to cause the malfunction of the capacitive screen. cell phone jammer can work when pressing the switch of power supply after finishing connecting the equipment.They can adjust and commission cell phone jammer
Another drawback of the capacitive screen with gloved hands or handheld does not respond to non-conductive objects touch, which is an increase of more insulation media. The major drawback of the capacitive screen Drift: When the ambient temperature, humidity change, the electric field of environmental change, will cause the drift of the capacitive screen, resulting in inaccurate. For example: boot monitor the temperature rise will cause drift: the user touches the screen, while your other hand or one side of the body near the display will drift; drift back capacitor larger objects moving near the touch screen, if you touch someone come around to watch caused by drift; capacitive screen drift reasons are technical deficiencies, and environmental potential surface (including the user's body) and capacitive touch screen, very near.
Than the finger area, they directly affect the location of touch. In addition, in theory, should be actually a linear relationship is nonlinear, such as: weight different or wet fingers extent different people take away the total amount of current is different, the total current changes and four sub-Current change is linear, this four corners of the capacitive touch screen used in custom polar coordinate system the origin of coordinates, the drift after the controller can not detect and recover, and four A / D completed by the the value of the four sub-flow to the touch points on the Cartesian coordinates X, Y coordinate values of complex calculations.
