And also, this kind of cell phone jammer is one of the main products.
Not easy to inadvertently. The capacitive touch screen sensor to the body's current, only the human body in order to operate, and will not touch with other objects accordingly, so basically to avoid the possibility of inadvertently. Durability. Compared to the resistive touch screen, capacitive touch screen in a dust-proof, waterproof, wear better performance. As a legitimate red touch-screen technology, the capacitive touch screen with a gorgeous interface, multi-touch, only the human body sensors and other advantages, but at the same time, it also has the following disadvantages: the accuracy is not high. For technical reasons, the accuracy compared to the capacitive touch screen resistive touch screen, which had been lacking. The advanced technology of cell phone jammer is adopted by more customers for the high quality and performance.
And only use your finger to input, difficult to achieve recognition complex on a small screen handwriting input. Vulnerable to environmental impact. Environmental factors like temperature and humidity changes can also lead to instability of the capacitive touch screen and even drift. Such as a user in the use of the body close to the screen may cause drift, even in a crowded operation can also cause drift. This is mainly due to the capacitive touch screen technology works, although the distance from the screen of the user's finger is closer, but around the screen, there are a lot of volume is much larger than the electric field of the fingers simultaneously, which would affect the judgment of the touch location. (3) high cost. In addition, the capacitive touch-screen touch pad attached to the LCD panel step there are still some technical difficulties, so virtually has also increased the cost of capacitive touch screen.
Thus, although using only two layers of ITO layer, but can reach up to 10 points touch operation. However, such technology, whether it is a conductive layer of planning, routing, or CPU operations, the difficulty have increased a lot, so need a more powerful processor. We need to note here is to achieve not only the capacitive screen multi-touch resistive screen can also be achieved, but because of the capacitive screen layer is its first ITO layer, a simple axis-interleaving technique that simply increase the ITO layers (ie, increase of its working-level) will be able to achieve multi-screen resistance layer is two ITO layer the middle of the ion layer, the principle of resistance screen can be used to increase the working layer to achieve more operation. This kind of mini portable cell phone jammer is one of the most popular and best received equipments.
