6英寸的触摸屏覆盆子π。与四线电阻屏幕相比,电容式触摸屏具有更好的光传感器和清晰度,当然,它们不能与表面声波屏幕和五线电阻屏幕进行比较。电容屏幕具有认真的思考。此外,电容技术的四层复合触摸屏在各种波长下具有光的光透射率,并且存在颜色失真的问题。由于层之间的光反射,图像字符变得模糊。电容屏幕原则上使用人体作为电容器元件的电极。当导体接近层时,当ITO工作表面之间耦合到足够的电容时,流动电流足以使电容屏幕发生故障。我们知道,尽管电容值与两极之间的距离成反比,但它与相对区域成正比,并且也与介电系数有关。因此,当大面积的棕榈或手持导电物体接近电容屏幕而不是触摸它时,它会导致电容屏幕出现故障。在潮湿的天气中,这种情况尤其严重。用手握住显示屏,距离显示器7厘米7厘米。 Within or within 15 cm of the body near the display can cause malfunction of the capacitive screen. Another disadvantage of capacitive screens is that they do not respond when touched with a gloved hand or a non-conductive object, because of the addition of a more insulating medium. The more major disadvantage of capacitive screens is drift: when the ambient temperature and humidity change, and the environmental electric field changes, it will cause the capacitive screen to drift, causing inaccuracies. For example: the temperature rises after the monitor is turned on, it will cause drift: when the user touches the screen, the other hand or the side of the body near the monitor will drift; the larger object near the capacitive touch screen will drift back after being moved. Will cause drift; the reason for the drift of the capacitive screen is technically inherent. Although the environmental potential surface (including the user's body) is far away from the capacitive touch screen, it is much larger than the area of ??the finger. They directly affect the determination of the touch position. . In addition, in theory, many relationships that should be linear are actually non-linear, such as: the total amount of current drawn by people with different weights or different degrees of wetness of their fingers is different, and the changes in the total amount of current and the changes in the four partial currents It is a non-linear relationship. The custom polar coordinate system of the four corners used by the capacitive touch screen does not yet have an origin on the coordinates. The controller cannot detect and recover after the drift. The calculation process from the flow value to the X and Y coordinate values ??of the touch point on the rectangular coordinate system is complicated. Because there is no origin, the drift of the capacitive screen is cumulative, and calibration is often required at the work site. The outermost silicon protective glass of the capacitive touch screen has good scratch resistance. However, it is afraid that a small hole will hurt the sandwich ITO if it is struck by nails or hard objects. Whether it is the sandwich ITO or the damage during installation and transportation, The inner surface of the ITO layer will not work properly.
