Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0025] As Figure 1 , Figure 2 and Figure 3 shown, in one embodiment, a touch heating keyboard 10 is provided. The touch heating keyboard 10 includes a cover plate 100, a capacitive touch module 200, a shielding and heating module, a backlight display module 400, and a bottom plate 500 arranged in sequence from top to bottom. The backlight display module 400 is configured to switch the display types of keyboard icons, symbols, letters, and numbers according to set instructions.

[0026] When the touch heating keyboard 10 in the above embodiments is in use, it is communicatively connected to the control center, so that the backlight display module 400 can be controlled by the control center to switch and display various types of keyboard icons, symbols, letters, and numbers to meet different input requirements. At the same time, the capacitive touch module 200 can generate corresponding control signals according to the positions touched by the fingers and transmit the control signals to the control center to input corresponding letters, numbers, and symbols. In addition, the shielding heating module can heat the cover plate 100 and the bottom plate 500 as needed to prevent the hands from getting frozen when using the keyboard in cold weather, thereby improving the comfort of the touch heating keyboard 10.

[0027] Specifically in this embodiment, the cover plate 100, the capacitive touch module 200, the shielding heating module, the backlight display module 400, and the bottom plate 500 are fixedly bonded to each other in an insulating manner. In cold weather, the shielding heating module can heat the cover plate 100 and the bottom plate 500 to normal temperature or a preset temperature.

[0028] Specifically in this embodiment, the capacitive touch module 200 can also generate command signals and feedback them to the control center, so that the control center can control the backlight display module 400 to switch the display types of keyboard icons, symbols, letters, and numbers according to the command signals and the set commands.

[0029] Among them, the touch heating keyboard 10 in this application is applicable to laptop computers and tablet computers.

[0030] As Figure 2 and Figure 4 shown, optionally, the capacitive touch module 200 is divided into a touch key area 210 and a touchpad area 220. In this way, the touch key area 210 and the touchpad area 220 are integrated together, which can reduce the development cost and the assembly cost, and can also reduce the product thickness, which is beneficial to the thin and light design of the touch heating keyboard 10.

[0031] It should be noted that the touch key area 210 can generate control signals by tapping. The touchpad area 220 can generate control signals by handwriting.

[0032] Optionally, the capacitive touch module 200 includes a first transparent insulating substrate, a touch driving layer formed by depositing and etching a transparent conductive material on one side of the first transparent insulating substrate, a second transparent insulating substrate, and a touch sensing layer formed by depositing and etching a transparent conductive material on one side of the second transparent insulating substrate. The touch driving layer and the touch sensing layer are fixedly bonded together.

[0033] Specifically in this embodiment, the touch driving layer and the touch sensing layer are fixedly bonded together by OCA (Optically Clear Adhesive) optical glue.

[0034] Specifically in this embodiment, electrodes arranged in a rectangular array are etched on both the touch driving layer and the touch sensing layer. The electrodes on the touch driving layer and the electrodes on the touch sensing layer are correspondingly bonded and fixed to assemble and form a capacitive touch module 200.

[0035] As Figure 2 shown, in one embodiment, the shielding and heating module includes a shielding layer 310, a third transparent insulating substrate, and a heating layer 320. The shielding layer 310 is fixed to one side of the third transparent insulating substrate and is bonded and fixed to the capacitive touch module 200. The heating layer 320 is fixed to the other side of the third transparent insulating substrate and is bonded and fixed to the backlight display module 400. In this way, the shielding layer 310, the third transparent insulating substrate, and the heating layer 320 form an integral structure, improving the convenience of assembling the touch heating keyboard 10. In addition, the shielding layer 310 can shield signals that interfere with touch, improving the reliability of the touch heating keyboard 10.

[0036] Specifically in this embodiment, the shielding layer 310 is configured to be made by depositing a transparent conductive material on the side of the third transparent insulating substrate close to the capacitive touch module 200; the heating layer 320 is configured to be made by depositing a transparent conductive material on the side of the third transparent insulating substrate close to the backlight display module 400. That is, both the shielding layer 310 and the heating layer 320 are a transparent conductive layer.

[0037] Optionally, the touch heating keyboard 10 further includes a flexible circuit board, and the flexible circuit board is electrically connected to the capacitive touch module 200, the shielding layer 310, and the heating layer 320. In this way, it is convenient to connect the touch heating keyboard 10 to the control center.

[0038] Among them, the number of flexible circuit boards can be flexibly adjusted according to actual usage needs. For example, the number of flexible circuit boards is three, and the capacitive touch module 200, the shielding layer 310, and the heating layer 320 are respectively communicatively connected to the control center through three flexible circuit boards. In other embodiments, the capacitive touch module 200, the shielding layer 310, and the heating layer 320 can share one flexible circuit board and are all communicatively connected to the control center through this flexible circuit board; or, the number of flexible circuit boards is two, the capacitive touch module 200 is separately communicatively connected to the control center through a flexible circuit board, while the shielding layer 310 and the heating layer 320 share another flexible circuit board and are communicatively connected to the control center.

[0039] In one embodiment, the backlight display module 400 includes a fourth transparent insulating substrate, a circuit layer, a backlight display layer, and a light-transmitting insulating layer arranged in sequence. The backlight display layer is configured to be able to switch the display types of keyboard icons, symbols, letters, and numbers according to set instructions. In this way, the light-transmitting insulating layer can protect the circuit layer and the backlight display layer, improving the reliability of the touch heating keyboard 10.

[0040] Specifically in this embodiment, the light-transmitting insulating layer can be made by coating and depositing a transparent insulating material on the side of the circuit layer away from the fourth transparent insulating substrate and on the side of the backlight display layer away from the fourth transparent insulating substrate.

[0041] Optionally, the circuit layer includes a circuit and pads. Both the circuit and the pads are configured to be formed by depositing a transparent conductive material and etching on the side of the fourth transparent insulating substrate close to the shielding heating module 300. The backlight display layer includes light-emitting diodes. The number of light-emitting diodes and the number of pads are both multiple, and each light-emitting diode is correspondingly mounted on each pad.

[0042] Specifically in this embodiment, the light-emitting diodes can be set as Mini LEDs (sub-millimeter light-emitting diodes) or Micro LEDs (micro light-emitting diodes). Each light-emitting diode is correspondingly mounted on each pad by means of chip bonding. Each pad is electrically connected to others through the circuit. The circuit can be electrically connected to the control center through a flexible circuit board or a USB interface.

[0043] In one embodiment, the cover plate 100 includes a fifth transparent insulating substrate and an ink border. The ink border is printed on the side of the fifth transparent insulating substrate close to the capacitive touch module 200. In this way, a window area is reserved in the fifth transparent insulating substrate, and the window area is correspondingly set with the capacitive touch module 200. The ink border blocks excess light and improves the comfort of the touch heating keyboard 10.

[0044] Among them, the first transparent insulating substrate, the second transparent insulating substrate, the third transparent insulating substrate, the fourth transparent insulating substrate, and the fifth transparent insulating substrate can all be set as any one of glass, PC (Polycarbonate) board, PET (Polyethyleneterephthalate) board, PMMA (Polymethyl methacrylate) board, CPI (Colorless Polyimide) board, COP (Cyclo Olefin Polymer) board, and composite boards. The value range of the thickness of the first transparent insulating substrate, the value range of the thickness of the second transparent insulating substrate, the value range of the thickness of the third transparent insulating substrate, and the value range of the thickness of the fourth transparent insulating substrate can all be set to be from 0.1 millimeter (mm) to 1.0 mm. The value range of the thickness of the fifth transparent insulating substrate can be set to be from 0.1 mm to 3.0 mm.

[0045] Among them, the transparent conductive material can be set as at least one of nanosilver wires, indium tin oxide, carbon nanotubes, and graphene.

[0046] Among them, the bottom plate 500 can be set as an insulating substrate, such as a glass plate, a PC board, a PMMA board, or a composite board. The bottom plate 500 is used to support and protect the backlight display module 400.

[0047] In one embodiment, the touch heating keyboard 10 further includes OCA optical glue. OCA optical glue is provided between the cover plate 100 and the capacitive touch module 200, between the capacitive touch module 200 and the shielding heating module, between the shielding heating module and the backlight display module 400, and between the backlight display module 400 and the bottom plate 500. In this way, the OCA optical glue has the characteristics of being colorless and transparent, having a light transmittance of more than 95%, good bonding strength, being curable at room temperature or medium temperature, and having small curing shrinkage, etc., improving the reliability of the touch heating keyboard 10.
