  What you need to know about the CTP cover glass?

       Glass variety, wide use, in addition to the common use of quartz glass, tempered glass, optical glass, color glass, laminated glass and other types.The material of glass is mainly composed of three parts: basic material, flux and stain, and also includes decolorizer, clarifier and emulsion.

   1. Silica

         Silicon dioxide is the main raw material for making glass. Silica is the main raw material for making glass. Different kinds of stones contain different amounts of silicon. These materials are more common in our life.

   2. The flux

          The melting point of silicon dioxide is very high, if you want to reach the melting point is very limited. So I try to add some other material to keep its melting temperature becomes lower down. When other silica melt very quickly, heating not gradually become soft filter in the process of transition, merged into some of the other material and make the glass melting process at different temperatures can be all kinds of state, is good for shaping and setting. This material is flux.

    3. Clarifying agent

        There are some bubbles in the glass making process, and the one used to reduce these bubbles is the clarifier.

    4. Milk inhibitor

         In glass production factory according to the customer's requirements, make the effect of opaque glass, make it opaque glass is milk inhibitor. It can make glass crystallization or not fixed colloid particles, the particles and the refractive index of different produce opaque glass itself. The effect of commonly used milk inhibitor with tin oxide, antimony oxide and phosphate.

    5. Decoloring agent

    Decolorizing agent is mainly used to eliminate the impurity in the raw material for glass undesirable color, make the effect of the glass show colorless transparent. Mainly include both chemical decoloring agent and material decoloring agent, chemical decoloring agent usually by oxidation decolorization, mainly sodium nitrate, potassium nitrate. Physical decoloring agent by producing complementary color and make the colorless glass, there are mainly, selenium and cobalt oxide and manganese dioxide oxidation bromide.

        The basic structure of CTP(Capacitive Touch Panel) is that the substrate is a single layer of plexiglass, which is uniformly forged on the inner and outer surface of the plexiglass with a transparent conductive film, and a long and narrow electrode on the four corners of the transparent conductive film on the outer surface.Its working principle is: when the finger touch capacitive touch screen, in working face through high frequency signal, at this point a finger and touch screen face form a coupling capacitance, the equivalent of a conductor, because work surface has high frequency signal, the fingers in touch points suck a little current, the small current respectively from touch screen on the four corners of the electrode, through the four electrodes with the finger to the four corners of the current is proportional to the linear distance, the controller through the calculation of the four current ratio, can be concluded that the contact point coordinate values.

     At present, the main structures in the market are G+F, G+F+F, G+G, P+F, P+F, and P+G.The capacitive screen is a four-layer composite glass screen. The inner surface of the glass screen and the interlayer are coated with ITO respectively. The outermost layer is the silicon glass protective layer only 0.0015mm thick.It can be simply viewed as a four-layer composite panel: the outer layer is the glass protective layer, followed by the conductive layer, the third layer is the non-conductive glass panel, and the innermost fourth layer is also the conductive layer.The inner conductive layer is the shielding layer, playing the role of shielding internal electrical signals. The middle conductive layer is a key part of the whole touch screen, with four corners or four edges with direct leads, responsible for the detection of the position of touch points.

     Topfoison is a supplier specialized in LCD display manufacturer and touch screen. In the part of CTP cover glass, our normal thickness is 0.55mm, 0.7mm, 0.95mm, 1.1mm, 1.6mm and 1.8mm.Generally speaking, the price factor that affects CTP cover plate glass has a lot of, the thickness of glass, the difficulty degree of craft, the demand of the market can affect price.For example, if R Angle wants to be 1, it should be at least 1.6mm thick cover glass. For mobile phones, it should be 0.55 and 0.7mm thick, while for consumer electronics, it should be 1.1mm thick.
