The technology improvement of cellphone jammer is the other concept

As indicated in Figure 4, plus a voltage from the panel Glass can be detected on the X-axis voltage, after A / D converter to get the X axis in the top panel Film. Similarly, the next panel Glass and a voltage can be detected from the top panel Film Y-axis voltage, after A / D converter to get the Y-axis coordinates. This action alternately read X and Y axes DATA constitutes a location point of the DATA. This is the basic working principle of resistive touch screen. Attention will have no contact with the upper and lower electrodes, contact resistance, and sometimes contact and non-contact repeatedly will lead to chaotic input signal, can not form a normal DATA fly lines exceptions. The good stability and reliability of    cell phone jammer can give the customer a better use experience.
ITO (indium oxide) in the conduction from the resistive touch screen role for weak conductors, the characteristic thickness down to 1800 angstroms (? = 10-10 m) below will suddenly become transparent, light transmission rate of 80% or more. ITO film is relatively thin and brittle fracture, smeared too thick will reduce the transmission and the formation of internal reflection to decrease the sharpness outside of the ITO film is more protective layer of a thin layer of plastic, but still easily damaged by sharp objects; and often touched, ITO using a certain time, hairline cracks will appear, and even distortion, such as the point of the outer layer of ITO damaged, while the fracture, they lose the role as conductors.  cell phone jammers is getting more market share and profit.
Electrodes on the touch screen used in the existing hand-held electronic products generally PET Film, and the lower electrode material according to the specific circumstances and requirements and selection of Film, Glass or Plastic. According to the different combinations of upper and lower electrode material, the touch screen can be divided into Film-Film (FF / FFSA), Film-Glass (FG), Film-Film-Glass (FFG), Film-Plastic (FP) and so on. Its advantages and disadvantages see table below: in which the material of the electrode PET Film Single layer and Double layer two kinds, the thickness of the two materials. The Single layer hardness up to 3H or more, cheaper, high turnover, mainly for the general standard products.   phone jammer also requires high.
The double layer consists of two film is relatively soft, which is characterized by hardness than the Single Layer, high wear resistance than the Single layer, anti-fly linear than the Single layer. Appropriate its price is also more expensive products generally used for higher requirements. The touch screen of the main technical parameters. The touch screen covering the LCD screen above the optical properties on the LCD display is extremely important. The transmittance of the touch screen is an important parameter, the transmittance of the size of Film and Glass Materials related. Usually touch-screen transmittance between 80-90%, with the parameters required to improve costs have been increased, depending on the specific use of occasions, the appropriate choice of transmittance. The technology improvement of    cellphone jammer is the other concept.
The optical properties require a higher color mobile phones require higher transmittance, and I am the Secretary to require suppliers to provide touch screen transmittance of about 85%. 85% transmittance of the touch screen touch screen prices more than 80% transmittance is about 10% anti-Newton ring (Anti-Newton-Ring/ANR). Newton rings cyclotomic ring regularity and arc-shaped non-regularity of Newton rings, when the touch screen materials and design in use, especially in the sun light, such as easy to see that the Newton ring, cause the text and linear distortion, seriously affect the display. Test Newton's ring method of standard three-wavelength fluorescent lamps, visual distance of 0.3m or more, a visual inspection by an angle of 60 degrees. So the use and work condition of    cell phone blocker should be commissioned.
