Embodiment 1
[0019] Embodiment 1 A conductive coating film 2 for heating is sandwiched between two layers of transparent glass, and metal electrodes 3 connected to wires 4 are respectively provided at both ends of the conductive coating film 2 for heating.
[0020] The two metal electrodes 3 are made of copper material with good thermal conductivity, with a thickness of 0.01 mm, and are pressed on the surface of the conductive coating 2 for heating. The conductive coating 2 for heating is a metal coating. The coating resistance can be calculated according to the actual calorific value by using Ohm's law and Joule's law. Because it has a certain resistance, it will generate a certain amount of heat when it is powered on. Therefore, The observation screen will not produce fog.
[0021] The wire 4 connected to the metal electrode 3 is a high-temperature lead wire with excellent flexibility, and the maximum current that can be used is 2A.
Embodiment 2
[0022] Example 2 as figure 1 As shown, a conductive coating film 2 for heating and a shielding layer are respectively sandwiched between three layers of ordinary transparent glass. A layer of conductive coating 2 for heating is sandwiched between the first layer of ordinary transparent glass 1 and the second layer of ordinary transparent glass 5. The conductive coating 2 for heating is respectively connected to a metal electrode 3 on the left and right, and the top of the metal electrode 3 is connected to a wire 4. The lower layer of conductive coating 2 for heating is the second layer of ordinary transparent glass 5, and there is a layer of wire mesh 6 sandwiched between the second layer of ordinary transparent glass 5 and the third layer of ordinary transparent glass 7. The wire mesh is generally black. It is required to choose the mesh number of the wire mesh 6. Generally, the mesh number of the wire mesh is selected from 40 mesh to 300 mesh, and the optimal mesh number of ...
Embodiment 3
[0023] Example 3 as figure 2 As shown, the first layer of ordinary transparent glass 1 is a display layer of transparent glass, the first layer of ordinary transparent glass 1 and the second layer of ordinary transparent glass 5 are sandwiched between the conductive coating 2 for heating, and the left and right sides of the conductive coating 2 for heating There are metal electrodes 3 for connecting wires respectively, a shielding wire mesh 6 is sandwiched between the second layer of ordinary transparent glass 5 and the third layer of ordinary transparent glass 7, the third layer of ordinary transparent glass 7 and the second layer of ordinary transparent glass 5 The other side of the opposite surface is coated with a conductive coating film 8 for shielding, that is, the innermost layer of transparent glass is coated with a conductive coating film 8 for shielding.
[0024] After the three layers of ordinary transparent glass in the above embodiment are pressed together, two i...
