Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present invention and should not be construed as limiting the present invention, and all other embodiments that can be obtained by one skilled in the art based on the embodiments of the present invention without inventive efforts shall fall within the scope of protection of the present invention.
The embodiment of the invention generally relates to a portable display device based on electronic skin, which utilizes a self-capacitance induction principle (the mutual capacitance induction principle can also be applied to the technical scheme of the invention) to sense the approaching degree of a conductor approaching to or contacting with the portable display device.
Referring to fig. 1, the portable electronic skin-based display device provided by the present invention includes a housing 10, a main control board 20 disposed on the housing 10, a detection circuit board 30, a light-emitting device 40, and an electrode 50, wherein the electrode 50 and a proximity conductor form a capacitance (air is an insulating medium), when the proximity conductor gradually approaches, the capacitance formed by the electrode 50 and the proximity conductor changes continuously, and the detection circuit board 30 can obtain a value representing a change in a distance between the proximity conductor and the electrode 50 through a change in the capacitance.
The detection circuit board 30 is electrically connected with the main control board 20, the detection circuit board 30 transmits an electrical signal for representing the distance or the change of the distance to the main control board 20, the main control board 20 can control the light change of the light emitting device 40 according to the electrical signal, and the light emitting device 40 can be an LED lamp, such as the color of the light, the brightness of the light, the flicker frequency of the light and the like, so that the distance change between the approach conductor and the electrode 50 is fed back through the light change.
Application scenario one (light color change):
the proximity conductor is close to the electrode 50 and will form a capacitance with the electrode 50 when it enters the sensing range of the electrode 50. Then, in the process of the approaching conductor gradually approaching, the distance d between the two plates corresponding to the capacitor gradually decreases (C ∈ S/4 π kd), so that the capacitor C of the capacitor formed by the approaching conductor and the electrode 50 gradually increases, and the change of the distance between the approaching conductor and the electrode 50 can be reflected by the change of the capacitor C.
The detection circuit board 30 transmits the obtained electrical signal for representing the distance or the change thereof to the main control board 20, and the main control board 20 can control the color change of the light emitting device 40 according to the electrical signal, and the distance between the approach conductor and the electrode 50 is reflected by the light of different colors. Example (c): the light emitting device 40 has seven color changes, wherein the seven colors are red, orange, yellow, green, cyan, blue and purple respectively, red indicates that the proximity conductor just enters the sensing range of the electrode 50, purple indicates that the distance between the proximity conductor and the electrode 50 is minimized, and orange, yellow, green, cyan and blue indicate that the distance between the proximity conductor and the electrode 50 is gradually reduced.
More specifically, in the process that the approaching conductor gradually approaches the electrode 50, when the light of the light emitting device 40 is red, it indicates that the approaching conductor has just entered the sensing range of the electrode 50, and if the approaching conductor continues to approach the electrode 50, the light of the light emitting device 40 changes from red to orange, then from orange to yellow, then from yellow to green, then from green to cyan, and then from cyan to blue, and when the light of the light emitting device 40 changes to violet, it indicates that the distance between the approaching conductor and the electrode 50 is minimum, and if the approaching conductor moves toward the electrode 50 again, it will collide with the electrode 50.
Application scenario two (light shading):
the proximity conductor is close to the electrode 50 and will form a capacitance with the electrode 50 when it enters the sensing range of the electrode 50. Then, in the process of the approaching conductor gradually approaching, the distance d between the two plates corresponding to the capacitor gradually decreases (C ∈ S/4 π kd), so that the capacitor C of the capacitor formed by the approaching conductor and the electrode 50 gradually increases, and the change of the distance between the approaching conductor and the electrode 50 can be reflected by the change of the capacitor C.
The detection circuit board 30 transmits the obtained electrical signal for representing the distance or the change thereof to the main control board 20, and the main control board 20 can control the brightness change of the light-emitting device 40 according to the electrical signal, and the light with different brightness reacts to approach the distance between the conductor and the electrode 50. Example (c): the darker the light of the light emitting device 40, the greater the distance between the conductor and the electrode 50, and the brighter the light of the light emitting device 40, the smaller the distance between the conductor and the electrode 50; alternatively, the brighter the light emitted from the light emitting device 40, the longer the distance between the proximity conductor and the electrode 50, and the darker the light emitted from the light emitting device 40, the shorter the distance between the proximity conductor and the electrode 50.
More specifically, assume that the darker the lamp light, the greater the distance between the proximity conductor and the electrode 50, and the brighter the lamp light, the smaller the distance between the proximity conductor and the electrode 50. In the process that the approach conductor gradually approaches the electrode 50, when the approach conductor just enters the sensing range of the electrode 50, the light of the light-emitting device 40 will be turned on, but the light is weak at this time, if the approach conductor continues to approach the electrode 50, the light of the light-emitting device 40 will gradually turn on, when the brightness of the light-emitting device 40 does not change any more, the distance between the approach conductor and the electrode 50 is very close, and if the approach conductor moves towards the electrode 50 again, the approach conductor will collide with the electrode 50.
Application scenario three (light flicker frequency change):
the proximity conductor is close to the electrode 50 and will form a capacitance with the electrode 50 when it enters the sensing range of the electrode 50. Then, in the process of the approaching conductor gradually approaching, the distance d between the two plates corresponding to the capacitor gradually decreases (C ∈ S/4 π kd), so that the capacitor C of the capacitor formed by the approaching conductor and the electrode 50 gradually increases, and the change of the distance between the approaching conductor and the electrode 50 can be reflected by the change of the capacitor C.
The detection circuit board 30 transmits the obtained electrical signal for representing the distance or the change thereof to the main control board 20, and the main control board 20 can control the light flicker frequency of the light-emitting device 40 according to the electrical signal, and the distance between the conductor and the electrode 50 is reflected by the different flicker frequencies of the light. Example (c): the lower the light flicker frequency of the light emitting device 40 is, the greater the distance between the conductor and the electrode 50 is, and the higher the light flicker frequency of the light emitting device 40 is, the smaller the distance between the conductor and the electrode 50 is; alternatively, a higher frequency of light emission from the light emitting device 40 indicates a greater distance between the conductor and the electrode 50, and a lower frequency of light emission from the light emitting device 40 indicates a smaller distance between the conductor and the electrode 50.
More specifically, it is assumed that the lower the light flicker frequency of the light emitting device 40, the greater the distance between the conductor and the electrode 50, and the higher the light flicker frequency of the light emitting device 40, the smaller the distance between the conductor and the electrode 50. In the process of approaching the approaching conductor to the electrode 50, when the approaching conductor just enters the sensing range of the electrode 50, the light emitting device 40 lights up and starts to blink, but the blinking frequency is low at this time, for example, 1 time of blinking in 1 second. If the approaching conductor continues to approach the electrode 50, the light flashing frequency of the light emitting device 40 will gradually increase, for example, to flash 2 times in 1 second, then flash 3 times in 1 second, and then flash 4 times in 1 second. When the light flicker frequency of the light emitting device 40 is stable, it indicates that the proximity conductor is close to the electrode 50, and when the proximity conductor moves toward the electrode 50 again, it collides with the electrode 50.
The portable display device based on the electronic skin is small in size, light in weight, convenient to carry when being powered on and convenient to carry when going out, and can display the function of the electronic skin through light change without carrying a mechanical arm to match with the function of displaying the electronic skin.
Referring to fig. 2-3, fig. 2-3 are schematic structural views of an embodiment of an electronic skin-based portable display device, which includes a housing 10, the housing 10 includes a front frame 11 and a bottom cover 12, an opening 13 is formed at a top of the housing, an electrode 50 is a conductive glass and is disposed at the opening, the conductive glass may be Indium Tin Oxide (ITO) conductive glass, and a light-emitting device 40 is disposed in a space enclosed by the conductive glass and the housing 10. Since the conductive glass is transparent, the light emitted from the light emitting device 40 under the conductive glass will penetrate through the conductive glass and exit the housing 10 through the opening 13, so that the function of the electronic skin can be displayed through the change of the light. Light emitting device 40 sets up in the inside of shell 10 and is located conductive glass's below, and it specifically can set up on the lateral wall all around of shell 10, also can set up in the bottom of shell 10, and as preferred, light-emitting device 40's light-emitting outlet is towards conductive glass and opening 13 to make the light that light emitting device 40 sent can all be emergent in the outside of shell 10, guarantee that the user can be comparatively clear observe the light change.
Referring to fig. 4, in some embodiments, the housing 10 has an opening, and the electrode 50 is also disposed at the opening, but the light emitting device 40 is located outside the housing 10. After the electrode 50 senses the approaching conductor, the detection circuit board transmits an electrical signal for representing the distance or the change thereof to the main control board 20, and the main control board controls the light change of the light emitting device 40 according to the electrical signal, for the light change, please refer to the related contents described above. The light emitting device 40 is disposed outside the housing 10, so that a user can directly observe the light change of the light emitting device 40, thereby knowing the function of the electronic skin. The light emitting device 40 may be disposed on the top of the housing, may be disposed on the peripheral side wall of the housing 10, and may be independent from the housing 10, and when the electronic skin needs to be displayed, the light emitting device 40 is electrically connected to the main control board 20 by means of a wire. Specifically, an interface may be disposed on the main control board 20, and the interface is exposed at one side of the casing 10 for the light emitting device 40 to be electrically connected thereto.
Referring to fig. 5, in some embodiments, the housing 10 is a non-conductor, the housing 10 has a plurality of electrodes 50 disposed in various directions, and the light emitting device 40 is disposed outside the housing 10. When the approaching conductor approaches to the electrode 50, because the housing 10 is a non-conductor, the approaching conductor still forms a capacitance with the electrode 50 disposed inside the housing 10, and the change of the distance between the approaching conductor and the electrode 50 can be represented by the change of the capacitance, and then displayed by the light change of the light-emitting device 40. The plurality of electrodes 50 distributed in various directions are disposed in the housing 10, and the electrodes 50 distributed in different directions can sense the approach of approaching conductors in different directions, so that the electrodes 50 can be approached from any direction without approaching in a specific direction when the electronic skin is displayed.
Referring to fig. 6, in some embodiments, the housing 10 is non-conductive and at least one side wall thereof is transparent, a plurality of electrodes 50 are disposed in the housing 10 and distributed in various directions, and the light emitting device is disposed in the housing 10. When the approaching conductor approaches to the electrode 50, because the housing 10 is a non-conductor, the approaching conductor still forms a capacitance with the electrode 50 disposed inside the housing 10, and the change of the distance between the approaching conductor and the electrode 50 can be represented by the change of the capacitance, and then displayed by the light change of the light-emitting device 40. When the electrode 50 senses that the approaching conductor approaches, the light emitting device 40 located in the housing 10 is turned on, light of the light emitting device 40 is emitted to the outside of the housing 10 through the light-transmitting sidewall, and if the approaching conductor continues to approach the electrode 50, the light of the light emitting device 40 is changed, and the light change is also displayed outside the housing 10 through the light-transmitting sidewall. The plurality of electrodes 50 distributed in various directions are disposed in the housing 10, and the electrodes 50 distributed in different directions can sense the approach of approaching conductors in different directions, so that the electrodes 50 can be approached from any direction without approaching in a specific direction when the electronic skin is displayed.
Referring to fig. 7, in some embodiments, the casing 10 is a light-transmitting casing, a plurality of electrodes 50 are disposed on an outer sidewall of the casing 10 and distributed in various directions, and the light-emitting device 40 is disposed inside the casing 10. The plurality of electrodes 50 distributed in various directions are disposed in the housing 10, and the electrodes 50 distributed in different directions can sense the approach of approaching conductors in different directions, so that the electrodes 50 can be approached from any direction without approaching in a specific direction when the electronic skin is displayed. When the approaching conductor approaches to the electrode 50, the electrode 50 arranged outside the housing 10 senses the approach of the approaching conductor, then the light-emitting device 40 is lighted and changed, and the light of the light-emitting device 40 is emitted outside through the housing 10, so that the user can observe the change of the light-emitting device 40, and the purpose of displaying the electronic skin function is achieved.
Referring to fig. 8, in some embodiments, the portable electronic skin-based display device of the present invention can also display the sensing function of the electronic skin through voice change/voice broadcast. When the approach conductor approaches the electrode 50, the sound generating device 60 will generate a warning sound with different volume, or directly broadcast the approach degree of the approach conductor and the electrode 50 in real time through voice. Example (c): the larger the sound volume, the smaller the distance between the proximity conductor and the electrode 50, and the smaller the sound volume, the larger the distance between the proximity conductor and the electrode 50; alternatively, the smaller the sound volume, the smaller the distance between the proximity conductor and the electrode 50, and the larger the sound volume, the larger the distance between the proximity conductor and the electrode 50.
More specifically, it is assumed that the greater the sound volume, the smaller the distance between the proximity conductor and the electrode 50, and the smaller the sound volume, the greater the distance between the proximity conductor and the electrode 50. When the approaching conductor just enters the sensing range of the electrode 50, the sound generator 60 starts to generate sound, but the sound is smaller, when the approaching conductor further approaches the electrode 50, the sound signal generated by the sound generator 60 gradually increases until the sound signal increases to no longer change, which indicates that the approaching conductor is close to the electrode 50, and if the approaching conductor moves toward the electrode 50 again, the approaching conductor collides with the electrode 50.
Or, when the proximity conductor just enters the sensing range of the electrode 50, the sound generating device 50 starts to broadcast the distance between the proximity conductor and the electrode 50, and in the process that the proximity conductor gradually approaches the electrode 50, the sound generating device 50 broadcasts the distance between the proximity conductor and the electrode 50 in real time, so that the sensing function of the electronic skin can be displayed.
Further, the light emitting device 40 and the sound emitting device 60 of the present invention can be selectively used, for example, a selection button is provided on the housing 10, and the electronic skin function can be selectively displayed through the light change or the sound change/voice broadcast. Of course, the display can also be performed through the light-emitting device 40 and the sound-generating device 60 at the same time, specifically, no matter the light-emitting device 40 adopts color change, light and shade change, or flicker frequency change, when the approaching conductor is infinitely approaching the electrode 50, since human eyes are required to observe, for example, whether the color changes to the purple color mentioned above, whether the zero degree of the lamp light changes to the maximum brightness and does not change any more, and whether the flicker frequency of the lamp light changes to the flicker most frequently and does not change any more, it is difficult to accurately judge that the approaching conductor is in the state of being very close to the electrode 50. In this case, the voice prompt may be provided by the sound generated by the sound generating device 60, such as an alarm sound. In addition, the function of the electronic skin can be displayed in a way of combining light and voice broadcast, including but not limited to this, and any realizable way belongs to the technical solution of the present invention, and is not limited herein.
Referring to fig. 9, in some embodiments, the portable display device based on electronic skin of the present invention can also display the sensing function of the electronic skin through animation display. When the proximity conductor is close to the electrode 50, an animation, such as that of a horse running, will appear on the display device 70, example: the faster the horse runs, the smaller the distance between the proximity conductor and the electrode 50, and the slower the horse runs, the larger the distance between the proximity conductor and the electrode 50; alternatively, the slower the horse runs, the smaller the distance between the proximity conductor and the electrode 50, and the faster the horse runs, the larger the distance between the proximity conductor and the electrode 50. Alternatively, the distance value between the proximity conductor and the electrode 50 is displayed on the display device 70, and the sensing function of the electronic skin is directly demonstrated by the distance value.
Taking the animation of the horse running as an illustration, it is assumed that the faster the horse runs, the smaller the proximity conductor is from the electrode 50, and the slower the horse runs, the greater the proximity conductor is from the electrode 50. When the approaching conductor has just entered the sensing range of the electrode 50, an animation of the horse running is displayed on the display device 70, but the horse running slower, and when the approaching conductor is further close to the electrode 50, the horse running speed on the display device 70 gradually increases until the horse running speed no longer changes, indicating that the approaching conductor is in close proximity to the electrode 50, and if the approaching conductor moves further towards the electrode 50, it will collide with the electrode 50.
As described above, the display device 70 according to the present invention can be used alternatively or simultaneously with the light emitting device 40, and the selection can be performed by the selection button provided on the housing 10.
