The elastic conductors 15 are respectively connected with a plurality of different pins of the electric control board 14, so that when a plurality of operators touch the glass substrate 10 at different touch patterns 111, the electric control board 14 can control the equipment using the display device to execute different functions; in other embodiments of the present application, an elastic conductive body 15 is connected to a plurality of pins of the electronic control board 14, so that after an operator touches the glass substrate at the touch pattern 111 corresponding to the elastic conductive body 15, the electronic control board 14 can control a device using the display device to perform a plurality of functions at the same time, for example, when the display device is applied to a water boiler, the operator can touch one touch pattern to simultaneously perform the functions of water supply and heating.
To facilitate the connection of the elastic electrical conductor 15 to the electronic control board 14, in some embodiments of the present application, the electronic control board 14 is provided with a pad abutting against the elastic electrical conductor 15.
The pad is a basic construction unit of surface mounting assembly of the electric control board 14 and is used for constructing a pad pattern of the circuit board, namely the pad is used for realizing connection of the elastic conductor 15 and the electric control board 14; in the embodiment of the application, the shape, the number, the size and the like of the bonding pads are not limited; for pad shape, in some embodiments of the present application, the pads may be square pads; in other embodiments of the present application, the pads may be open-shaped pads; the number of the pads is equal to the number of the elastic conductors 15, and when the elastic conductors 15 are springs or metal elastic pieces, the connection strength between the elastic conductors 15 and the pads can be enhanced by soldering.

The interference fit is that the aperture of the hole is expanded so as to be sleeved on the shaft, when the aperture of the hole is restored, the shaft of the hole generates a clamping force to connect the part with the hole with the shaft, and the expanded aperture generally utilizes the elasticity of materials or heats the part with the hole to expand the aperture of the hole; or the shaft diameter of the shaft is reduced and then inserted into the hole, the hole shaft generates a clamping force when the shaft diameter of the shaft recovers, and the shaft diameter is reduced by cooling the shaft by using elasticity of materials or liquid nitrogen; and the tolerance band of the bore is below the tolerance band of the shaft.
In the embodiment of the present application, since the pad is connected to the electric control board 14, and the conductive silver paste layer 12 covers the touch pattern 111, the pad and the conductive silver paste layer 12 are not easy to heat, and the manufacturing cost of the display device is increased by adopting a liquid nitrogen cooling material to reduce the shaft diameter, therefore, the elastic conductive body 15 is in interference fit with the pad and the conductive silver paste layer 12 by using the elasticity of the material in the embodiment of the present application; because the material of conductive silver paste layer 12 and pad is difficult to produce elastic deformation, therefore, the interference fit of elastic conductor 15 and pad and conductive silver paste layer 12 is realized by the elasticity of elastic conductor 15 in the embodiment of the present application.

Through the above embodiment, when the light transmittance of the glass substrate 10 is within this range, and the display device is in the screen saver state, the glass substrate 10 is in a black and light-tight state, and the touch pattern 111 sprayed on the glass substrate 10 is shielded and hidden, that is, an operator can only observe the black glass substrate 10 and cannot see the electric control board 14, the backlight module 13 and the like inside the glass substrate 10, so that the display device has good consistency in visual effect when in the screen saver state; in one embodiment of the present application, the glass substrate 10 has a light transmittance of 50%. The light transmittance is the capacity of light to penetrate through a medium, and is the percentage of luminous flux penetrating through a transparent or semitransparent body to incident luminous flux, and can represent the efficiency of penetrating light of a display device and the like, and the light transmittance directly influences the visual effect of the touch screen; for example, when parallel monochromatic light passes through a uniform, non-scattering medium, a portion of the light is absorbed, a portion passes through the medium, and a portion is reflected by the surface of the medium.

In addition, since the electroplating can enhance the corrosion resistance, hardness, wear resistance, conductivity, smoothness, heat resistance, etc. of the electroplated object, after the electroplated layer 16 is disposed on the front surface of the glass substrate 10, the smooth electroplated layer 16 is convenient for the operator to slide on the display device, and the glass substrate 10 is protected by the strong hardness, corrosion resistance and wear resistance.
In the embodiments of the present application, the thickness, material, and electroplating process of the electroplated layer 16 are not limited, and the thickness of the electroplated layer 16 requires that the electroplated layer 16 not only can protect the glass substrate 10, but also can ensure that light emitted from the backlight module 13 can penetrate through the electroplated layer 16, and in some embodiments of the present application, the thickness of the electroplated layer 16 is 1 μm; as for the material of plating layer 16, in some embodiments of the present application, plating layer 16 may be formed by mixed material plating, for example, gold and silver mixed plating, zinc and silver mixed plating, or the like; in other embodiments of the present application, plating layer 16 may be a single material, for example, copper or zinc plating; for the electroplating process of electroplated layer 16, in some embodiments of the present application, electroplated layer 16 may be formed by a barrel plating process; in other embodiments of the present application, electroplated layer 16 may be formed by a rack plating process.

In the embodiment of the present application, the thickness, size, shape, and the like of the light-shielding layer 113 are not limited as long as the light-shielding layer 113 can shield the light emitted by the backlight module 13 from penetrating through the light-shielding layer 113; because the light that backlight unit 13 sent is mixed light, for improving the ability that light shield layer 113 blocks light, consequently, in some embodiments of this application, light shield layer 113 adopts black printing ink silk screen printing on glass substrate 10, so, no matter the light that backlight unit 13 sent is mixed light or monochromatic light, black light shield layer 113 can absorb the light of various colours.
