The tft capacitive touch manufacturer tells you that as a very common commercial touch screen TFT LCD screen, it can be seen in all walks of life and scenes.

Low price tft capacitive touch from China manufacturer
tft capacitive touch technology uses the human body's current induction to work. The capacitive touch screen is a four-layer composite glass screen. The inner surface of the glass screen and the partition are coated with a layer of ITO, and the outermost layer is a thin silicon glass protective layer. The ITO coating is used as the working surface, four electrodes are drawn from the four corners, and the inner ITO layer is used as the shielding layer to ensure a good working atmosphere. When the finger touches the metal layer, due to the electric field of the body, the user and the user, the TFT liquid crystal capacitor touch screen surface forms a coupling capacitor. For high frequency currents, the capacitor is a direct conductor, so the finger draws a small current from the point of contact. The current flows from the electrodes at the four corners of the touch screen, and the current passing through the four electrodes is proportional to the distance from the finger to the four corners. The manufacturer of the control tft capacitive touch tells you that the controller obtains the position of the contact by accurately calculating the four current ratios.
In addition, purchasing sputtering equipment is relatively time-consuming, and the purchase cycle is at least half a year. Due to the time-consuming sputtering process and slow expansion of production capacity, manufacturers cannot increase production according to the original production capacity. According to Foxconn's OCA demand estimate, Apple iPad orders are expected to reach 40 million units in the coming year; the production capacity of the touch screen factory is far from enough, and this is also a problem that we urgently need to solve.
This is what we are going to talk about today, TFT's knowledge about LCD capacitive touch screens. The manufacturer of tft capacitive touch tells you that if you have any questions, you can contact our online customer service staff at any time.
