Home appliance panel glass

Home appliance panel glass product description: The fine glass is heated to about 650 °C, and then rapidly cooled, so that the glass surface is in a high degree of compaction (and compressive stress) while the middle part adheres to a compensatory force (ie, tensile stress).  The surface compressive stress can resist the various tensions causing the glass to break, so that the mechanical strength of the home appliance panel glass is multiplied, and the impact force, the bending resistance force, and the temperature difference resistance are both advanced by 3-5 times compared with the general glass, and After breaking, the glass fragments are in pure angular granules, and the maximum limit avoids damage to the human body. Other notes: Standard: Maximum standard: 3050mm  x 8300mm minimum standard: 25mm x 25mm thickness 0.5-20 lead standard: GB9963 "tempered glass" national standard, so tempered glass is a legal safety glass.

It is not a simple home appliance panel glass , but a layer of special metal conductive material is attached to the surface of the glass . It is commonly called a capacitive touch screen. When the finger touches the metal layer, the capacitance of the contact will change and make it connected. The oscillator frequency is changed, and the measurement of the frequency can be used to determine the touch orientation to obtain information, and then the various circuit functions are completed through the reaction circuit.

Under normal circumstances, it is completed by the principle of capacitive sensing, such as the capacitance of the mobile phone out of the touch screen, and the touch button on the glass panel of the induction cooker.  The touch capacitive screen is to distinguish the orientation of the user's touch by the size of the capacitor corresponding to the user's different orientations, and then further control the display device and call the corresponding processing program to complete the user's touch operation function.

In order to reduce the cost of small appliances such as induction cookers, a dedicated capacitive touch button is used to view the chip to view the user's touch input.  In fact, the device under the touch panel orientation of the glass plate has a corresponding sensing electrode, which is connected to the touch button to view the viewing pin of the chip, when our finger is close (by a layer of glass) or when the electrode is touched, the human body The conductivity changes the capacitance of the electrode. After the change of the capacitor is viewed by the chip, the corresponding viewing data is output, and then the MCU distinguishes the operation.
