Detailed Description
Specific embodiments of the utility model are further described below with reference to the accompanying drawings:
please refer to fig. 1 to 5. The digital display screen with good touch feeling comprises a display screen bracket 1, a driving circuit board 2, a touch membrane 3 and an elastic foam layer 4. Wherein:
the display screen support is used for fixing the driving circuit board and the touch membrane. The display screen bracket comprises a containing cavity 11 and a bracket display hole 12. Wherein:
the accommodating cavity 11 is arranged on the back surface of the display screen bracket and is recessed towards the front surface. The accommodating cavity is mainly used for accommodating and fixing the driving circuit board 2.
The bracket display hole 12 is arranged on the front surface of the display screen bracket and is communicated with the accommodating cavity. The support display hole is mainly used for transmitting light, so that light emitted by the display LED arranged on the drive circuit board can be transmitted out from the upper surface of the display screen support through the support display hole, and the corresponding display pattern is displayed by combining the touch membrane.
The driving circuit board 2 is fixed on the back of the display screen bracket. The front surface of the driving circuit board 2 is provided with a display LED (not shown in the figure), and the display LED is arranged opposite to the bracket display hole.
The touch membrane 3 is fixed on the front surface of the display screen bracket, and the touch membrane is electrically connected with the driving circuit board. The touch film is provided with a touch pattern and a display pattern. The touch pattern is mainly used for clearly indicating touch operation buttons, and corresponding operation can be triggered by pressing the touch pattern. The display pattern is mainly used for clear or current working states such as temperature, time, what state is currently in, and the like.
The elastic foam layer 4 is arranged between the front surface of the display screen bracket and the touch membrane. The elastic foam layer has elasticity, so that soft and elastic touch feeling is generated when the touch membrane is pressed.
According to the touch screen, the elastic foam layer is arranged between the front surface of the display screen support and the touch membrane, and is contracted downwards when a user presses the touch membrane through the elasticity and elasticity of the elastic foam layer, and is reset upwards after the pressing is finished, so that the touch membrane is not hard and soft and flicked, the touch feeling is better, and the user experience is better.
In order to prevent the elastic foam layer from blocking the light emitted by the display LED from penetrating out of the upper surface of the display screen bracket through the bracket display hole, the elastic foam layer 4 is provided with a light transmission hole 41 opposite to the bracket display hole.
Because the elastic foam layer is very soft and the light holes are not easy to process, the thin elastic foam layer can lead to the fact that the light holes cannot be processed, and in addition, the touch membrane is easy to shift when the elastic foam layer is too thick, so that the thickness of the elastic foam layer is preferably 0.5-2 mm. In this embodiment, the thickness of the elastic foam layer is preferably 1 mm, so that the elastic foam layer not only has proper elasticity, but also has a perfect combination with the touch film, and the appearance is also attractive.
Since Ethylene-Propylene-Diene Monomer (EPDM) is a terpolymer of Ethylene, propylene and a non-conjugated Diene, the Ethylene-Propylene-Diene Monomer has superior oxidation resistance, ozone resistance and corrosion resistance, and the elastomeric foam layer is preferably Ethylene-Propylene-Diene Monomer foam in consideration of the requirements of insulation, oxidation resistance and corrosion resistance of the digital display screen. So that the elastic foam layer can resist heat, light, oxygen, especially ozone, and has the advantages of resistance to polar solutions and chemicals, low water absorption and good insulating property.
In this embodiment, the touch film 3 includes a color film layer 31, a light blocking layer 32, a circuit printing layer 33, and an adhesive layer 34. Wherein:
the color film layer 31 is a light-transmitting film, and is printed with touch patterns and display patterns, and the display patterns are opposite to the bracket display holes.
The light blocking layer 32 is arranged on the back surface of the color film layer; the light blocking layer is arranged outside the display pattern to prevent the light blocking layer from blocking the display pattern. The light blocking layer is mainly used for avoiding the influence on the appearance of the circuit printing layer from the front. The light blocking layer is printed on the back surface of the color film layer by black oil.
The circuit printed layer 33 is provided on the back surface of the light blocking layer, and a touch circuit is printed on the circuit printed layer. The circuit printing layer is mainly used for realizing the touch function.
An adhesive layer 34 is provided on the back of the circuit-printed layer. The adhesive layer is mainly used for pasting the touch membrane.
In this specific embodiment, the elastic foam layer is adhered and fixed on the front surface of the display screen bracket, and the touch membrane is adhered and fixed on the front surface of the elastic foam layer.
In order to fix the driving circuit board conveniently, the display screen bracket 1 further comprises a positioning column 13 arranged on the back of the accommodating cavity, the driving circuit board 2 is provided with a positioning hole 21 matched with the positioning column, and the positioning column is inserted into the positioning hole. The positioning column can fix the driving circuit board on the display screen bracket in a melting mode, and of course, the positioning column can also be fixed in an adhesive or fastening mode.
In order to fix the display screen support on the casing of the electric appliance such as the oven, the sweeper, etc., the display screen support 1 further comprises a hook 14 disposed on the side edge of the display screen of the support and protruding downwards. So that the electric appliance shell can be clamped with the corresponding buckle on the electric appliance shell through the clamping hook.
According to the touch screen, the elastic foam layer is arranged between the front surface of the display screen support and the touch membrane, and is contracted downwards when a user presses the touch membrane through the elasticity and elasticity of the elastic foam layer, and is reset upwards after the pressing is finished, so that the touch membrane is not hard and soft and flicked, the touch feeling is better, and the user experience is better.
