In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The invention provides a touch control glass module which can be used as a window glass, namely the touch control glass module can be arranged on a frame of a window to form the window of an automobile. The touch control glass module can form front and rear windshields of an automobile, and can also form side window glass of the automobile. The structure and application of the touch glass module of the present invention are described in detail below with reference to the embodiments.
Referring to fig. 1, a touch glass module 1 according to an embodiment of the invention includes an outer glass 10, a dimming film 20, a touch layer 30, and an inner glass 40.
The touch glass module 1 of the embodiment of the invention is arranged on a frame of a vehicle window when in use and is connected with a corresponding control module arranged in an automobile. The outer pane 10 serves as the outer layer of the window, facing the outside of the vehicle; the inner pane 40 serves as an inner layer of a window, facing the inside of the vehicle. The outer layer glass 10 may be a conventional automotive glass, such as a conventional tempered glass. The dimming film 20 is a film capable of adjusting transmittance, and can be controlled by a control module provided in the vehicle to change transmittance, reflectance, and haze. The touch layer 30 is used for detecting a touch signal to provide a human-computer interaction interface. The driver and the passenger perform touch operation on the surface of the inner layer glass 40. The inner layer glass 40 can be ordinary automobile glass or can be replaced by a PE film.
When the touch layer 30 detects that a touch action occurs, the control module controls the light transmittance of the dimming film layer 20 according to the touch signal. Therefore, drivers and passengers can perform touch operation according to different comfort level requirements to change visual effects and improve safety. For example, when strong light is emitted from the outside, the light transmittance of the dimming film layer 20 can be reduced, so that the probability of safety accidents caused by eyes being stimulated by strong light in the driving process of the automobile is greatly reduced.
According to some embodiments of the present invention, the touch layer 30 is formed on the surface of the inner layer glass 40, and the inner layer glass 40 is bonded to the surface of the outer layer glass 10. As shown in fig. 1, the touch layer 30 may be directly molded on the surface of the inner glass 40 opposite to the outer glass 10, the light modulation film layer 20 is disposed on the surface of the outer glass 10, and then the inner glass 40 having the touch layer 30 is bonded to the surface of the outer glass 10 by using an OCA (optical clear adhesive) or an OCR (optical clear adhesive) layer, so that the outer glass 10, the light modulation film layer 20, the touch layer 30, and the inner glass 40 are assembled together to form the touch glass module 1. The touch layer 30 is formed on the surface of the inner layer glass 40, so that the assembling process of the touch glass module 1 is simplified. It is understood that in other embodiments of the present invention, the touch glass module 1 may not have the inner layer glass 40. For example, the touch layer 30 may be directly formed on the inner surface of the outer glass 10. For another example, the touch layer 30 may be formed on the surface of the dimming module 20 close to the outer glass 10.
The touch layer 30 may be an Indium Tin Oxide (ITO) touch layer or a touch layer formed of a metal mesh, directly molded on the surface of the inner layer glass 40. For example, referring to fig. 1 and 8, when the touch layer 30 is an ITO touch layer, the inner glass 40 having the ITO touch layer can be obtained by exposing, developing and etching an indium tin oxide conductive film disposed on a glass substrate to obtain a desired touch pattern. For another example, referring to fig. 9 and 10, when the touch layer 30 is formed using a metal mesh, the metal mesh may be formed on a glass substrate. The metal grid can be obtained by exposing, developing and etching the nanoscale metal film; the metal grid touch layer can also be obtained by arranging a polymer layer on a glass substrate, stamping the polymer layer to form a required grid shape, and filling a conductive material in the grid-shaped grooves. When the touch layer 30 is formed using the silver nanowires, the silver nanowires may be embedded in a matrix. ITO, metal grid and nano silver wire are mature technologies and can provide a stable touch operation interface.
According to some embodiments of the present invention, the touch layer 30 has a touch operation area 310, which is in a bar shape; alternatively, the touch operation area 310 includes a plurality of touch points.
As shown in fig. 2 and 3, the touch operation area 310 may be configured as a bar shape. In other words, the touch operation area 310 is configured as a touch slider. A strip-shaped touch operation area 310 can be seen from the surface side of the inner layer glass 40; or the bar-shaped touch operation area can be displayed only when the touch action is generated. Thus, the driver and the passenger can slide along the length direction of the touch operation area 310 to generate different touch signals, so that the driver and the passenger can perform touch operation according to different comfort level requirements to change the visual effect. The touch operation area 310 is arranged in a bar shape or a dot shape, and can be operated by sliding or touching, so that the normal operation habit is met. As shown in fig. 2, the length direction of the touch operation area 310 may be along the transverse direction, and when the touch glass module 1 is mounted to an automobile, the length direction of the touch operation area 310 is consistent with the width direction of the automobile, so that a driver and a passenger can slide left and right to realize touch operation. As shown in fig. 3, the length direction of the touch operation area 310 may also be vertical, and when the touch glass module 1 is mounted to an automobile, the length direction of the touch operation area 310 is consistent with the height direction of the automobile, and a driver and a passenger may slide up and down to realize touch operation.
Referring to fig. 4, an appearance effect of the touch operation area 310 during touch operation is illustrated. When viewed from the surface side of the inner layer glass 40, the shift "-" symbol and the shift "+" symbol are visible. The control module of the automobile can set that when sliding from the gear "-" symbol to the gear "+" symbol, the number of the indication bars 312 is gradually increased, and the light transmittance of the dimming film layer 20 is increased; when the light source slides in the opposite direction, the number of the indication bars 312 gradually decreases, and the transmittance of the dimming film 20 decreases. Like this, the driver and crew can conveniently adjust the gear of touch-control draw runner through the draw runner, and then adjust the luminousness of the rete 20 of adjusting luminance.
Referring to fig. 5, an arrangement of the touch layer 30 when the touch operation area 310 is a touch slider is illustrated. Specifically, the touch layer 30 is in a strip shape and includes a plurality of first electrodes 320 and a plurality of second electrodes 330, wherein each first electrode 320 is connected to a common lead 340, and each second electrode 330 is connected to a lead 331. The second electrode 330 includes a first portion 332 and a second portion 332 connected to the lead 331, and the first portion 332 and the second portion 333 respectively extend between adjacent two first electrodes 320. Thus, the first electrode 320 and the second electrode 330 form a surrounding structure. The common lead 340 and the lead 331 are used to connect to the touch IC module. Thus, the first electrode 320 and the second electrode 330 form a plurality of sensing channels, each sensing channel corresponds to a different voltage control condition, and the light transmittance of the dimming film 20 is adjusted at any time through sliding touch. In this embodiment, all the first electrodes 320 form a touch signal emitting layer (i.e., the first electrodes 320 are driving electrodes), and all the second electrodes 330 form a touch signal receiving layer (i.e., the first electrodes 320 are sensing electrodes). However, it should be noted that the sensing electrode and the driving electrode are not distinguished, and therefore the first electrode 320 and the second electrode 330 are specifically used as electrodes of that type, which depends on the touch IC module of the IC manufacturer.
Referring to fig. 6, another arrangement of the touch layer 30 when the touch operation area 310 is a touch slider is illustrated. Specifically, the touch layer 30 includes a plurality of electrode blocks 350 arranged along a straight line, each electrode block 350 is independently connected with an ITO lead 352, and the shape of the electrode blocks 350 is configured such that the adjacent electrode blocks 350 can complement each other to form a surrounding structure. Each electrode block 350 is connected to the touch IC module through an ITO lead 352, respectively, thereby providing a touch sensing area.
Referring to fig. 7, a schematic structural diagram of the touch operation area 310 including a plurality of touch points is shown. Specifically, the touch operation area 310 of the touch layer 30 includes a plurality of circular electrode units 360, each of which is independently connected with a lead 362 and connected to the touch IC module. As an illustration, only one electrode unit 360 is depicted in fig. 7 by way of example. When the electrode unit 360 is touched, the touch IC module determines whether a touch action occurs and a touch position by detecting whether an electric field at the position of the electrode unit 360 is changed. Thus, when different electrode units 360 are touched, the touch IC module detects different touch signals, so that the driver and passengers can conveniently touch the electrode units 360 at different positions to adjust the transmittance of the dimming film 20.
It is understood that one or more positions of the touch operation area 310 on the touch glass module 1 may be provided. For example, when the touch glass module 1 constitutes a front windshield, the touch operation regions 310 may be provided at a driver position and a position corresponding to a passenger seat.
It is understood that the area of the touch operation area 310 is set to be smaller than the area of the outer glass 10. The area of the touch operation area 310 can meet the operation requirement, and the whole outer layer glass 10 does not need to be covered, so that the structural complexity is reduced.
According to some embodiments of the present invention, the light modulating film layer 20 is a polymer dispersed liquid crystal layer. The light modulation film layer 20 may be a Polymer Dispersed Liquid Crystal layer (PDLC). The PDLC layer is a composite film with dielectric anisotropy and micron-sized liquid crystal droplets uniformly dispersed in a polymer network, has electro-optic response characteristics, can work between a scattering state and a transparent state, and has certain gray scale. The PDLC layer is thus a film that can adjust the light passing state. When the touch signal is generated, the control module may change the voltage of the dispersed liquid crystal in the dimming film layer 20 according to the touch signal, and the refractive index of the dispersed liquid crystal is changed, so that the light transmission state of the PDLC layer is changed. For example, when illuminated by intense light, no electric field may be applied and the PDLC assumes an opaque state. And when an electric field is applied, light can penetrate the PDLC layer. The PDLC layer is combined with the touch layer, so that the optical effect of the touch control type control automobile glass can be realized, the touch sense and visual sense experience of a human-computer interaction interface are increased, richer and more intelligent touch sense and visual experience are provided for automobile drivers and passengers, and the intelligent application of automobile touch control is enhanced.
According to some embodiments of the present invention, the areas of the dimming film layer 20 and the touch layer 30 are both smaller than or equal to the outer glass 10.
For example, in some embodiments, as shown in fig. 2 and 3, the touch layer 30 is an ITO touch layer, and as shown in fig. 9, the touch layer 30 is a metal mesh touch layer, wherein the dimming film layer 20 and the touch layer 30 are both in accordance with the area of the outer glass 10. For example, the entire touch glass module is covered with the dimming film layer 20, the touch layer 30 and the inner glass 40. In this way, the touch glass module 1 can be standardized without considering the problem of how to set the position of the touch layer 30. At this time, any position can be used as the touch operation area 310
Of course, the areas of the dimming film layer 20 and the touch layer 30 may be smaller than the area of the outer layer glass 10. Therefore, the dimming film layer 20 can be arranged at a specific position of the front windshield or the side window, and the cost is reduced. For example, in the embodiment shown in fig. 8, the touch layer 30 is an ITO touch layer, wherein the areas of the dimming film layer 20 and the touch layer 30 are smaller than the area of the outer glass 10. For another example, as shown in the embodiment shown in fig. 10, the touch layer 30 is a metal mesh touch layer, wherein the areas of the dimming film layer 20 and the touch layer 30 are both smaller than the area of the outer glass layer 10. When the touch glass module 1 includes the inner layer glass 40, the area of the inner layer glass 40 may be smaller than or equal to the area of the outer layer glass 10.
An embodiment of the invention further provides a vehicle-mounted dimming system based on the touch glass module 1, and the light transmittance of a vehicle window can be adjusted automatically according to needs. Referring to fig. 11, the vehicle-mounted dimming system includes the touch glass module 1, the touch IC module 2, the dimming film layer control module 3, and the main control module 4 (i.e., the Host control module) according to any of the embodiments.
Specifically, the touch IC module 2 is electrically connected to the touch layer 30. The dimming film control module 3 is electrically connected to the dimming film 20. The main control module 4 is electrically connected to the touch IC module 2 and the dimming film control module 3, wherein the main control module 4 controls the dimming film control module 3 according to a signal of the touch IC module 2, thereby controlling the dimming film 20. In this embodiment, the dimming module 20 is a PDLC layer, and the dimming film layer control module 3 is a PDLC control module.
The main control module 4 may be an embedded Digital Signal Processor (DSP), a Microprocessor (MPU), an Application Specific Integrated Circuit (ASIC), a Programmable Logic Device (PLD), or the like. It is to be understood that the present embodiment is not limited to a specific type of the main control module 4. The touch IC module 2, the dimming film layer control module 3, the main control module 4, and the like may be built in a center console of the automobile.
Above-mentioned on-vehicle dimming system can in time adjust the luminousness of adjusting luminance rete 20 through touch-control operation in good time according to the external illumination condition, and the security when having improved the car and traveling has still strengthened human-computer interaction's experience.
According to some embodiments of the invention, a power module 420 is also included. The power supply module 420 may be integrated in the main control module 4 to supply power to the dimming film layer control module 3 and other elements. The power supply module 420 may have an electric power storage function, so that even if the vehicle is in a stationary state and the engine is not started, the driver and passengers in the vehicle can adjust the light transmittance of the dimming film 20 at a proper time through touch operation.
