Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

Fig. 1 is a schematic structural diagram of a touch display device according to an embodiment of the present application. As shown in fig. 1, the touch display device 1 includes: a braille display screen 10 and a touch component 20.

Optionally, fig. 2 is a schematic structural diagram of a braille display screen in the touch display device according to an embodiment of the present application. As shown in fig. 2, the braille display screen 10 includes a floating-point carrier 11 and a plurality of floating points 12, wherein:

the floating points 12 are used for selectively protruding out of the floating point carrier 11 to display the dot words.

Because a plurality of floating points can be selectively protruded out of the floating point carrier, each floating point has two states of 'convex' and 'flat', floating points (m x n floating points in total) in each m x n floating point array (m and n are integers larger than 0) can represent a dot word (namely a Chinese character) by the combination of the two states of 'convex' and 'flat', and a visually impaired person can read the dot word by touching the concave-convex feeling on the dot word display screen.

The touch component 20 is configured to obtain a touch operation of at least one floating point of the plurality of floating points 12, and execute an operation instruction according to the touch operation and a floating point position of the at least one floating point.

Here, the operation instruction may instruct the braille display screen to switch the displayed braille or instruct an operation of an external connection device connected to the touch display apparatus. Of course, the operation command may also be other commands, such as a command for instructing the touch display device to turn off.

The touch display device can not only display the braille through a plurality of floating points which can float up and down (namely selectively protrude out of the floating point carrier) on the braille display screen, but also can acquire touch operation aiming at least one floating point in the plurality of floating points on the braille display screen through the touch assembly and execute corresponding operation instructions according to the touch operation and the floating point position. Therefore, the visually impaired people can read the braille displayed on the braille display screen in a touch mode, can directly perform touch operation on the braille display screen according to different user requirements, is simple and convenient to operate, solves the problem that the visually impaired people cannot conveniently operate the common touch display screen, improves user experience, and improves the confidentiality of user confidential information compared with a mode of voice playing or dictation by other people.

In an application scenario, when a visually impaired person uses an ATM to inquire account balance, the visually impaired person touches a braille display screen of the touch display device to read operation prompt information on the braille display screen, and if "click can check account balance", the visually impaired person can click any floating point in the braille display screen (star) composed of a plurality of floating points according to the operation prompt information, and then the visually impaired person can touch and read the account balance displayed on the braille display screen. Therefore, the visually impaired people can use the touch display device conveniently and conveniently, and the security of the confidential information of the user can be ensured.

The number of floating points can be set according to actual needs, and is usually a multiple of 6. For example, a chinese character may correspond to a braille having a floating point lattice of 4 × 6 (i.e., m is 4, n is 6, and there are 24 floating points), and as shown in fig. 3, the floating point lattice may be divided into 4 parts: the front phonetic character A, the back phonetic character B, the prefix part C and the end part D, each part is represented by a 2-3 floating point lattice (namely 6 floating points).

In order to facilitate the visually impaired people to touch the adjacent braille, two braille characters can be separated by using a "division character space", as shown in fig. 3, the division character space can be a floating point lattice of 6 × 1, and a column of division character spaces E1 and E2 is added at the head and the tail of the braille character, so that the floating point lattice of 6 × 6 in total represents one braille character (corresponding to one Chinese character). If the braille display screen is a 90 x 30 floating-point dot matrix, five lines can be represented, and each line has 15 Chinese characters at most. Of course, one or more columns may be added between two braille to distinguish between words, which is not limited herein.

In addition, it should be further noted that the above touch operation for floating point includes: the method comprises the steps of single-point or double-point operation of a single floating point, single-point preset duration operation of the single floating point, single-point operation of a plurality of floating points, single-point operation of the plurality of floating points according to a preset sequence and the like.

Fig. 4 is a schematic structural diagram of a touch display device according to another embodiment of the present disclosure. As shown in fig. 4, the braille display screen 10 further includes: at least one floating point driving component 13, wherein the at least one floating point driving component 13 is used for driving at least one floating point of the plurality of floating points 12 to protrude out of the floating point carrier 11.

Optionally, the number of the floating point driving components 13 may be multiple, and each of the floating point driving components is used for driving one floating point of the multiple floating points 12 to protrude from the floating point carrier 11.

Here, the floating point driving assembly 13 may be an electromagnetic floating point driving assembly, and at least one floating point of the plurality of floating points 12 is driven to protrude from or be parallel to the floating point carrier 11 by using the principle of ampere's rule and magnet repulsion and attraction, but the floating point may be driven by other methods, such as a mechanical method.

It should be noted that the plurality of floating point driving units 13 may be independent from each other or may be integrated.

With continued reference to fig. 4, the touch device 20 includes: at least one touch detection component 21 and a digital display control component 22, wherein the at least one touch detection component 21 is used for detecting touch operation of at least one floating point in the plurality of floating points 12; the braille display control module 22 is connected to the at least one touch detection module 21, and is configured to execute an operation instruction according to the touch operation and a floating point position of the at least one floating point.

Optionally, the number of the touch detection components 21 may be multiple, and the multiple touch detection components are respectively used for detecting a touch operation of one floating point of the multiple floating points.

Here, the number of the touch detection elements 21 may be less than or equal to the number of the floating points 12.

When the number of the touch detection assemblies is equal to the number of the floating points, one touch detection assembly corresponds to one floating point, and one touch detection assembly detects the touch operation of one floating point. When the number of the touch detection assemblies is smaller than the number of the floating points, one touch detection assembly can correspond to the floating points (smaller than the total number of the floating points) in the characteristic area of the braille display screen one by one, and the specific area can be a floating point area which is set in advance according to the operation habit of a user. Of course, one touch detection assembly may also correspond to a plurality of floating points, one touch detection assembly detects a touch operation of at least one of the plurality of floating points, and when any of the plurality of floating points is touched, the touch detection assembly may detect the touch operation.

It should be noted that the touch detection elements 21 may be independent from each other or may be integrated.

To more clearly illustrate the technical solution of the present application, a floating point (i.e. a target floating point 12') of the floating points 12 and a corresponding floating point driver 13' and a touch monitor unit 21' are described as an example.

As shown in fig. 5 to 10, the floating point driver 13' includes: a first magnetic body 131 'and a second magnetic body 132', wherein the first magnetic body 131 'includes an iron core and a coil wound around the iron core, and the second magnetic body 132' is a permanent magnet. When the coil is energized (forward or reverse current), the first magnetic body 131 'generates a magnetic field, which attracts or repels the second magnetic body 132'.

Here, it should be noted that the arrangement positions of the first magnetic element 131' and the second magnetic element 132' may be various, and it is sufficient that the target floating point 12' can be driven to protrude or be parallel to the floating point carrier 11.

In one embodiment, as shown in fig. 5 and 6, the first magnetic body 131' may be disposed at an upper end of the floating point hole 14' corresponding to the target floating point 12' on the floating point carrier 11, and the second magnetic body 132' may be disposed at a bottom of the target floating point 12 '.

When the first magnetic body 131' is not powered on, the target floating point 12' is located in the floating point hole 14' due to gravity, or when the first magnetic body 131' is powered on, a first magnetic field is generated, and under the action of the first magnetic field, the first magnetic body 131' and the second magnetic body 132' repel each other, and the target floating point 12' sleeved with the second magnetic body 132' is located in the floating point hole 14 '. At this time, the state of the target floating point 12' is "flat".

When the first magnetic element 131' is powered on or a second current opposite to the first current is powered on, a second magnetic field is generated, the first magnetic element 131' and the second magnetic element 132' attract each other under the action of the second magnetic field, and the second magnetic element 132' drives the target floating point 12' to move upwards and protrude out of the floating point carrier 11. At this time, the state of the target floating point 12' is "convex".

Optionally, the first magnetic element 131 'and the second magnetic element 132' may be both annular, the first magnetic element 131 'is embedded in the upper end of the floating point hole 14', and the second magnetic element 132 'is sleeved on the bottom of the target floating point 12'.

Of course, the second magnetic element 132' may be disposed at the upper end of the floating point hole 14' corresponding to the target floating point 12' on the floating point carrier 11, and the first magnetic element 131' may be disposed at the bottom of the target floating point 12 '. The working principle is similar to that of the above embodiments, and is not described in detail here.

In another embodiment, as shown in fig. 7 and 8, the first magnetic body 131' may be disposed at the bottom of the floating point hole 14' corresponding to the target floating point 12' on the floating point carrier 11, the second magnetic body 132' may be disposed at the bottom of the target floating point 12', or the target floating point 12' itself may be the first magnetic body 131 '.

When the first magnetic body 131 'is not energized, the target floating point 12' is located in the floating point hole 14 'due to gravity, or when the first magnetic body 131' is energized with a first current, a first magnetic field is generated, and under the action of the first magnetic field, the first magnetic body 131 'and the second magnetic body 132' attract each other, and the target floating point 12 'is located in the floating point hole 14'. At this time, the state of the target floating point 12' is "flat".

When the first magnetic element 131' is powered on or a second current opposite to the first current is powered on, a second magnetic field is generated, under the action of the second magnetic field, the first magnetic element 131' and the second magnetic element 132' repel each other, and the second magnetic element 132' drives the target floating point 12' to move upward and protrude out of the floating point carrier 11. At this time, the state of the target floating point 12' is "convex".

Of course, the second magnetic element 132' may be disposed at the bottom of the floating point hole 14' corresponding to the target floating point 12' on the floating point carrier 11, and the first magnetic element 131' may be disposed at the bottom of the target floating point 12' or the target floating point 12' itself may be the first magnetic element 131 '. The working principle is similar to that of the above embodiments, and is not described in detail here.

Here, the floating point driving unit 13' has various structures, and is not limited to the structure that drives at least one floating point of the plurality of floating points by using the ampere rule and the principle that magnets repel each other.

As shown in fig. 5-10, the touch detection device 21' includes: the trigger 211' and the trigger switch 212' are disposed opposite to each other, and when a touch operation is generated on the target floating point 12', that is, the target floating point 12' in the "convex" state is subjected to the touch operation in the arrow direction in the figure, for example, the target floating point is clicked (or pressed), the trigger 211' corresponding to the target floating point 12' triggers the corresponding trigger switch 212' to perform state switching.

Here, the states of the trigger switch 212' include "on" and "off", and the corresponding state switching includes: switched from "on" to "off" and/or switched from "off" to "on".

Thus, in the case where the target floating point 12' is in the "convex" state, it is possible to detect whether the target floating point 12' has a touch operation according to the state switching of the trigger switch 212', determine that the touch operation of the target floating point 12' has been detected if the trigger switch 212' has a state switching, and determine that the touch operation of the target floating point 12' has not occurred if the trigger switch 212' has not a state switching.

It should be noted that the state switching of the trigger switch 212' may be a state switching, such as switching from "on" to "off" or switching from "off" to "on", or a plurality of state switching, such as switching from "on" to "off" and then switching from "off" to "on".

Taking the touch operation as a single-click operation and the initial state of the trigger switch 212' is "off" as an example, the target floating point 12' protrudes out of the floating point carrier 11, the target floating point 12' drives the trigger 211' to contact the trigger switch 212' due to the single-click operation, the trigger switch 212' is switched from "off" to "on" for the first time, and then the target floating point 12' is automatically reset along the reverse direction of the arrow in the figure to drive the trigger 211' to be away from the trigger switch 212', and the trigger switch 212' is switched from "on" to "off" for the second time, in this example, the trigger switch 212' is switched from "on" to "off" twice.

It should be noted that the above mentioned reverse reset of the target floating point 12 'along the arrow in the figure can be realized by the floating point driving component 13', for example, by the first magnetic body 131 'and the second magnetic body 132', when the target floating point 12 'is subjected to the single-click operation, it overcomes the attraction or repulsion of the first magnetic body 131' and the second magnetic body 132', and the trigger 211' is contacted with the trigger switch 212', and after the single-click operation is finished, the target floating point 12' is restored to the original state, i.e. the "convex" state due to the attraction or repulsion between the first magnetic body 131 'and the second magnetic body 132'.

In order to facilitate the floating point to return to the initial state, i.e. reset, as shown in fig. 4, the braille display screen 10 further includes: at least one floating point resetting element 15 is used for resetting, i.e. restoring, at least one of the plurality of floating points 12 to an initial state, which may be "convex" or "flat".

As shown in fig. 4, there may be a plurality of floating point reset units 15, each for resetting one of the floating points 12.

Here, the floating point returning member 15 may be a rubber cap, or may be another elastic returning member such as a spring.

Still taking the target floating point 12' as an example, assume that the initial state of the target floating point 12' is "convex" and the corresponding floating point reset is 15 '. As shown in FIG. 9, the target floating point 12 'is in a "flat" state and the reset element 30' is compressed. As shown in fig. 10, after the target floating point 12' is subjected to the single click operation, the target floating point 12' may be restored to the original state (i.e., the "convex" state) by the floating point reset unit 31' in addition to the attractive force or repulsive force between the first magnetic body 131 and the second magnetic body 132.

When the reset piece 30' is compressed, the trigger piece 211' may or may not be in contact with the trigger switch 212 '.

In order to enhance the comfort of touch and prevent sundries from falling into the floating dot holes, as shown in fig. 9 and 10, the dot display screen 10 further includes: and the elastic film 16 is arranged on the surface of the braille display screen 10.

In order to prevent the floating point from shaking, as shown in fig. 4, the braille display screen 10 further includes: a floating point lock 17 for locking at least one of the plurality of floating points 12.

As shown in fig. 4, the floating point locking unit 17 is provided in plural numbers, and is used for locking one floating point of the plural floating points 12.

Still taking the target floating point 12' as an example, assume that the floating point lock of the target floating point 12' is 17 '. As shown in fig. 9 and 10, when the state of the target floating point 12' is "flat" or "convex", the floating point lock 17' locks the target floating point 12', respectively.

Here, the floating point locking member 17 may be a resilient clip, a bump (see fig. 9 and 10), a rubber ring, or the like, and may be provided on and/or in the floating point hole.

Fig. 11 is a schematic structural diagram of a self-service device according to an embodiment of the present application. As shown in fig. 11, the self-service device includes the touch display device 1 in any of the embodiments.

The self-service equipment can not only display braille through a plurality of floating points on the braille display screen in the touch display device, but also can acquire touch operation aiming at least one floating point in the plurality of floating points on the braille display screen through the touch assembly in the touch display device and execute corresponding operation instructions according to the touch operation and the floating point position.
