Description

Technical Field

[0001] The present application relates to the technical field of electronic atomizers, and in particular to a capacitive touch screen assembly and an electronic atomizer device. Background Art

[0002] Capacitive touch screens are commonly used to implement touch screen functions in mobile phones, monitors and other products. When a user touches a capacitive screen, a coupling capacitor is formed between the user's finger and the work surface due to the human body's electric field. Since the work surface is connected to a high-frequency signal, the finger absorbs a very small current, which flows out from the electrodes on the four corners of the screen. In theory, the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the position information by accurately calculating the ratio of the four currents.

[0003] The above-mentioned capacitive touch screen has a complex structure and requires an independent controller and touch chip to detect the specific position of the touch point. It can also complete complex touch functions such as single-point, multi-point, and sliding. It is costly and is not suitable for electronic atomizer applications with simple control functions (such as only having a switch function and / or a gear adjustment function). Utility Model Content

[0004] The present application provides a capacitive touch screen assembly and an electronic atomization device to solve the problem of high cost when the existing four-layer touch screen is used in an electronic atomizer application solution that only needs to realize one or a few touch functions.

[0005] In order to solve the above technical problems, the technical solution provided by this application is:

[0006] In a first aspect, a capacitive touch screen assembly is provided, which is applied to an electronic atomization device, wherein the capacitive touch screen assembly includes a cover plate and a display screen; the cover plate includes a transparent substrate and a transparent conductive layer, wherein the transparent substrate has a substrate front side and a substrate back side arranged opposite to each other, the substrate front side is used for being touched by a user, and the transparent conductive layer is arranged on the back side of the substrate, and the transparent conductive layer is provided with a first electrical contact point; the display screen is stacked with the cover plate, the display screen is located on the side of the transparent conductive layer away from the transparent substrate, the display screen is provided with a second electrical contact point, and the first electrical contact point and the second electrical contact point are conductively connected.

[0007] According to an embodiment of the present application, a touch signal wiring is provided on a side of the display screen facing the transparent conductive layer, and the second electrical contact point is provided on the touch signal wiring.

[0008] According to an embodiment of the present application, the second electrical contact point is connected to the first electrical contact point by pressing.

[0009] According to an embodiment of the present application, the capacitive touch screen assembly further includes a main control board and a flexible circuit board, and the main control board is electrically connected to the touch signal trace through the flexible circuit board to detect the capacitance change of the transparent conductive layer.

[0010] According to one embodiment of the present application, both the first electrical contact point and the second electrical contact point are silver paste contact points.

[0011] According to an embodiment of the present application, the first electrical contact point and the second electrical contact point are both located at the periphery of the effective display area of ​​the display screen.

[0012] According to an embodiment of the present application, the touch signal line is printed by conductive silver paste, and the touch signal line is located at the periphery of the effective display area of ​​the display screen; or, the touch signal line is made of transparent conductive material.

[0013] According to one embodiment of the present application, the transparent conductive layer includes a conductive area or at least two conductive areas separated from each other, each of the conductive areas is provided with a first electrical contact point; the touch signal routing includes at least one line, one of the lines corresponds to one of the first electrical contact points, and each of the lines is provided with a second electrical contact point.

[0014] In a second aspect, an electronic atomization device is provided, comprising the above-mentioned capacitive touch screen assembly.

[0015] According to one embodiment of the present application, the electronic atomization device further includes a housing, and the capacitive touch screen assembly is disposed on the housing and the front side of the transparent substrate is exposed from the housing.

[0016] The beneficial effects of this application are:

[0017] The capacitive touch screen assembly and electronic atomization device provided by the present application are provided with a transparent conductive layer on a transparent substrate, and the transparent conductive layer corresponds to the touch area. When the user's finger touches the front surface of the transparent substrate, a coupling capacitor is formed between the human body and the transparent conductive layer, so that the capacitance value on the transparent conductive layer changes. Since the transparent conductive layer and the display screen are electrically connected through the first electrical contact point and the second electrical contact point, the capacitance value change signal of the transparent conductive layer can be led out to the relevant capacitance detection mechanism such as the main control chip on the main control board through the first electrical contact point and the second electrical contact point, so as to control the function of the touch area through the main control board. The present application does not need to judge the specific position of the touch. As long as the finger touches the front surface of the transparent substrate so that the human body and the transparent conductive layer form a coupling capacitor, the touch function can be realized. Compared with the existing four-layer capacitive touch screen, the structure of the present application is simpler and the cost is lower. In addition, in the present application, the transparent conductive layer is arranged on the transparent substrate. In this way, as long as the transparent conductive layer and the display screen can be electrically connected through the electrical contact points, the transparent substrate and the transparent conductive layer can be set larger than the display screen, and the position of the touch area on the transparent substrate can be arbitrarily selected. For example, the touch area can be set in the middle of the transparent substrate or in the corner of the transparent substrate. Therefore, the present application has greater selectivity for the position of the touch area, and different touch area positions can be designed according to different appearance requirements of the product. In addition, especially when the display screen is small, the touch area can be set larger, which is more convenient for touch control. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The present application provides a capacitive touch screen assembly, which is applied to an electronic atomization device, which generally refers to a device that generates an aerosol with a specific smell by heating and atomizing. Figures 1 to 3 , Figure 1 is a schematic diagram of the exploded structure of an exemplary embodiment of a capacitive touch screen assembly provided by the present application, Figure 2 yes Figure 1 The installation flow chart of the first structure of the capacitive touch screen assembly, Figure 3 yes Figure 1 A front view of a second structure of a capacitive touch screen assembly is shown. In this embodiment, the capacitive touch screen assembly includes a cover plate 100 and a display screen 200 which are stacked.

[0029] The cover plate 100 includes a transparent substrate 110 and a transparent conductive layer 120. The transparent substrate 110 has a substrate front surface 110a and a substrate back surface 110b disposed opposite to each other. The substrate front surface 110a is for a user to touch. The transparent conductive layer 120 is disposed on the substrate back surface 110b. The transparent conductive layer 120 is provided with a first electrical contact point 121. Both the transparent substrate 110 and the transparent conductive layer 120 are transparent structures and do not affect the display effect of the display screen 200.

[0030] The transparent substrate 110 can be made of glass, polyethylene terephthalate (PET), polycarbonate (PC), or acrylic (PMMA). It is understood that the transparent substrate 110 is a transparent insulating plate with a certain hardness, which does not affect the display effect of the display screen 200 and can have a certain protective isolation effect on the transparent conductive layer 120.

[0031] The transparent conductive layer 120 can generally be made of materials such as indium tin oxide (ITO for short), and the indium tin oxide material can be plated on the transparent substrate 110 by magnetron sputtering. It should be understood that in other embodiments, the transparent conductive layer 120 can also be made of other transparent conductive oxides, not limited to ITO. In one embodiment, the transparent conductive layer 120 can be integrally arranged on the back side 110b of the transparent substrate 110. When the transparent conductive layer 120 is plated on the transparent substrate 110 by ITO, the transparent conductive layer 120 is integrally arranged on the transparent substrate 110.

[0032] The display screen 200 is located on the side of the transparent conductive layer 120 away from the transparent substrate 110 . The display screen 200 is provided with a second electrical contact point 201 . The first electrical contact point 121 and the second electrical contact point 201 are conductively connected.

[0033] It can be seen that the present application sets a transparent conductive layer 120 on the transparent substrate 110, and the transparent conductive layer 120 plays a touch function. When the user touches the front side 110a of the transparent substrate 110 with a finger, a coupling capacitor is formed between the human body and the transparent conductive layer 120 due to the electric field of the human body, so that the capacitance value on the transparent conductive layer 120 changes. Since the transparent conductive layer 120 and the display screen 200 are electrically connected through the first electrical contact point 121 and the second electrical contact point 201, the capacitance value change signal of the transparent conductive layer 120 can be led out through the first electrical contact point 121 and the second electrical contact point 201 to the relevant capacitance detection mechanism, such as the main control chip on the main control board, so that the function of the touch area is controlled by the main control board. This application does not need to determine the specific location of the touch. As long as the finger touches the front side 110a of the transparent substrate 110 so that the human body and the transparent conductive layer 120 form a coupling capacitor, the touch function can be realized. Compared with the existing four-layer capacitive touch screen, this application is more suitable for electronic atomizer applications that only need to realize one or a few touch points. Its structure is simpler and the cost is lower.

[0034] In the related art, the transparent conductive layer 120 is usually directly arranged on the display screen 200, and the transparent substrate 110 is only used as a protective layer. However, for electronic atomization devices, the area of ​​the display screen 200 is usually relatively small, and the user's fingers can only touch the touch area within a very small range. The position of the touch area is also relatively optional. In the present application, the transparent conductive layer 120 is arranged on the transparent substrate 110. In this way, as long as the transparent conductive layer 120 and the display screen 200 can be electrically connected through electrical contact points, the transparent substrate 110 and the transparent conductive layer 120 can be set larger than the display screen 200, and the position of the touch area on the transparent substrate 110 can be arbitrarily selected. For example, the touch area can be set in the middle of the transparent substrate 110, or it can be set in the corner of the transparent substrate 110. Therefore, the present application has greater selectivity for the position of the touch area, and different touch area positions can be designed according to different appearance requirements of the product. In addition, especially when the display screen 200 is small, the touch area can be set larger to facilitate users to quickly achieve touch control. Figure 2 The transparent substrate 110 and the transparent conductive layer 120 are shown in FIG. 1 and FIG. 2 , respectively. The transparent substrate 110 and the transparent conductive layer 120 are shown in FIG. 2 and FIG. 3 , respectively. Figure 3 The case where the areas of the transparent substrate 110 and the transparent conductive layer 120 are larger than the display screen 200 is shown.

[0035] In addition, if the conductive layer corresponding to the touch area is usually directly arranged on the display screen 200 (the conductive layer of this structure is usually a transparent conductive layer), or is separately arranged on the outside of the display screen 200 (the conductive layer of this structure is usually a conductive metal plate), and then the substrate is installed on the conductive layer, for this separation scheme of the substrate and the conductive layer, since there is a certain gap between the substrate and the conductive layer, different individual products of the same batch may have different gaps between the substrate and the conductive layer due to installation errors when they are installed, resulting in inconsistent touch sensitivities of different individual products of the same batch. In the present application, the transparent conductive layer 120 is directly arranged on the transparent substrate 110, and the transparent conductive layer 120 and the transparent substrate 110 are installed as a whole. Therefore, there is no gap between the transparent conductive layer 120 and the transparent substrate 110, and there will be no problem of inconsistent sensitivity due to installation gap errors. Therefore, the touch sensitivity consistency of the present application is better, especially when the transparent conductive layer 120 is plated on the transparent substrate 110 using ITO, the size of the transparent conductive layer 120 is highly accurate, the thickness is uniform, and the touch sensitivity consistency is better.

[0036] In some embodiments, the display screen 200 may be a liquid crystal display (LCD). There are many types of liquid crystal display screens, such as a liquid crystal transistor liquid crystal display screen or a twisted nematic liquid crystal display screen. The liquid crystal display screen may generally include a first glass substrate 210, a second glass substrate 220, and a liquid crystal 230 located between the first glass substrate 210 and the second glass substrate 220. The first glass substrate 210 is located on a side of the second glass substrate 220 close to the transparent conductive layer 120, and the second electrical contact point 201 is disposed on a side of the first glass substrate 210 facing the transparent conductive layer 120. It should be understood that in order to achieve the display effect of the liquid crystal display screen, the liquid crystal display screen should also include a backlight source (not shown in the figure). The structure of the liquid crystal display screen is a relatively mature technology in the relevant technology. Since the present application does not involve the improvement of the internal structure of the liquid crystal display screen, only the general structure of the liquid crystal display screen is listed here, and the internal structure of the liquid crystal display screen is not specifically described.

[0037] See also Figure 4 , Figure 4 2 is an exploded schematic diagram of another embodiment of the capacitive touch screen assembly provided by the present application. Based on the above embodiments, in this embodiment, a touch signal line 202 is provided on the side of the display screen 200 facing the transparent conductive layer 120, and the second electrical contact point 201 is provided on the touch signal line 202. Specifically, the touch signal line 202 is provided on the side of the first glass substrate 210 of the display screen 200 facing the transparent conductive layer 120, and the second electrical contact point 201 can be provided at the end of the touch signal line 202.

[0038] In some embodiments, the second electrical contact 201 is connected to the first electrical contact 121 by pressing, which enables the second electrical contact 201 and the first electrical contact 121 to form a whole, with better connection stability and less prone to loosening or poor contact.

[0039] The first electrical contact point 121 and the second electrical contact point 201 can be silver paste contact points. Silver paste has a conductive effect, so it can achieve a conductive connection between the first electrical contact point 121 and the second electrical contact point 201. The first electrical contact point 121 and the second electrical contact point 201 can be processed by directly dropping liquid silver paste on the transparent conductive layer 120 and the display screen 200 and waiting for it to solidify.

[0040] When the first electrical contact point 121 and the second electrical contact point 201 are made of silver paste, since silver paste is an opaque material, in order to prevent the silver paste from affecting the display effect of the display screen 200, the first electrical contact point 121 and the second electrical contact point 201 can be arranged outside the effective display area (Active Area) of the display screen 200. The concept of the effective display area of ​​the display screen 200 refers to the total area of ​​the display screen 200 that can display text and graphics.

[0041] The touch signal trace 202 can also be printed with conductive silver paste. Since the silver paste is an opaque material, in order to prevent the silver paste from affecting the display effect of the display screen 200, the touch signal trace 202 can also be arranged outside the effective display area of ​​the display screen 200. The touch signal trace 202 can also be made of a transparent conductive material, and the transparent conductive material can be made of materials such as ITO. Since the transparent conductive material does not affect the display effect of the display screen 200, there is no restriction on the positional relationship between the touch signal trace 202 and the effective display area of ​​the display screen 200.

[0042] See again Figure 4On the basis of the above embodiments, in this embodiment, the capacitive touch screen assembly further includes a main control board 400 and a flexible printed circuit (FPC) 300, and the touch signal line 202 is connected to the main control board 400 through the flexible printed circuit 300. Specifically, a screen drive interface 203 is provided near the edge of the display screen 200, the touch signal line 202 is connected to the screen drive interface 203, the internal lines of the display screen 200 itself are also connected to the screen drive interface 203, and the screen drive interface 203 is connected to the flexible printed circuit board 300, that is, the touch signal line 202 and the internal lines of the display screen 200 itself are connected to the flexible printed circuit board 300 by binding. The main control board 400 is provided with a main control chip 410, and the main control chip 410 has a touch detection foot 411. The flexible circuit board 300 is connected to the touch detection foot 411 through a wire 500 to achieve a conductive connection between the transparent conductive layer 120 and the main control chip 410, so as to detect the capacitance change of the transparent conductive layer 120, and then the function of the touch area can be controlled by the main control board 400. In this embodiment, the touch signal line 202 on the display screen 200 is led out through the flexible circuit board 300. It can be understood that in other embodiments, the touch signal line 202 can also be led out by other means other than the flexible circuit board 300.

[0043] See also Figure 5 , Figure 5 It is a schematic diagram of various structures of the transparent conductive layer 120. The transparent conductive layer 120 includes a conductive area 120a or at least two conductive areas 120a separated from each other. Each conductive area 120a is provided with a first electrical contact point 121. Correspondingly, the touch signal trace 202 includes at least one line, one line corresponds to one first electrical contact point 121, and each line is provided with a second electrical contact point 201. When the number of the conductive areas 120a of the transparent conductive layer 120 is one, a single touch area structure is formed. When the number of the conductive areas 120a of the transparent conductive layer 120 is two or more, two or more touch areas are formed. The functions corresponding to the touch areas of the electronic atomization device can generally be switches, gear adjustment, etc. Figures 1 to 4 The case where the transparent conductive layer 120 includes two conductive regions 120a separated from each other is shown.

[0044] Each conductive region 120a of the transparent conductive layer 120 may also be designed into different patterns and position distributions according to different applications and requirements. The shape of each conductive region 120a of the transparent conductive layer 120 may be circular, rectangular or polygonal.

[0045] When the transparent conductive layer 120 has only one conductive area 120a, i.e., a single touch area, a first electrical contact point 121 is set in the conductive area 120a, and the number of lines of the touch signal routing 202 on the display screen 200 is one, and a second electrical contact point 201 is set on the line, and the line is bound to the flexible circuit board 300, and the flexible circuit board 300 is connected to the touch detection pin 411 of the main control chip 410 through a wire 500, thereby realizing electrical conduction from the main control chip 410 to the single touch area, so as to realize touch detection of the single touch area.

[0046] When the transparent conductive layer 120 has two or more conductive areas 120a, i.e., two or more touch control areas, the number of the conductive areas 120a, the number of the first electrical contacts 121, the number of the second electrical contacts 201, the number of the touch signal traces 202 on the display screen 200, the number of the touch detection pins 411 of the main control chip 410, and the number of the wires 500 between the main control chip 410 and the flexible circuit board 300 are all the same, for example Figures 1 to 4 As shown, when the transparent conductive layer 120 has two conductive areas 120a, each conductive area 120a is provided with a first electrical contact point 121, and the touch signal routing 202 on the display screen 200 has two lines, each line is provided with a second electrical contact point 201, and each line is bound to the flexible circuit board 300. The flexible circuit board 300 leads out two wires 500 which are respectively connected to the two touch detection pins 411 of the main control chip 410, thereby realizing the electrical conduction from the main control chip 410 to the two touch control areas respectively, so as to realize the touch detection of the two touch control areas respectively.

[0047] When the transparent conductive layer 120 includes two or more mutually isolated conductive regions 120 a , excess conductive material may be removed by etching on the entire surface of the transparent conductive layer 120 , thereby forming a plurality of mutually isolated conductive regions 120 a .

[0048] The present application also provides an electronic atomization device, which includes a capacitive touch screen assembly. The specific structure of the capacitive touch screen assembly refers to the above embodiment. Since the electronic atomization device adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here. Among them, the electronic atomization device generally refers to a device that heats and atomizes to produce an aerosol with a specific smell.

[0049] The electronic atomization device further includes a housing, the capacitive touch screen assembly is disposed in the housing, and the transparent substrate 110 is exposed to the housing for user touch control. In one embodiment, a through hole is provided on the housing, the capacitive touch screen assembly is disposed in the housing, and the cover plate 100 and the display screen 200 are exposed to the through hole, and the side of the cover plate 100 facing away from the display screen 200 may protrude from the housing, may be flush with the housing, or may be recessed relative to the housing.
