Specifically, the display device of the embodiment is mainly used for vehicle-mounted display, and the feedback method at least comprises a safety mode, in the safety mode, the vehicle infotainment system can only reserve basic functions, such as functions of navigation, telephone, music, air conditioner and the like, and other application functions, such as games, videos and the like, can be disabled, so that the operation of a user is simplified. In the safe mode, when the display device does not detect any touch operation, the display device can display a corresponding picture according to the working condition of the vehicle infotainment system at that time, but does not display any function key C. For example, if the vehicle uses the navigation function, the display device displays only the screen of the navigation route; if the vehicle plays music, the display device only displays the picture of the music, and the picture can comprise the name of the music, the name of a singer, the duration and the like; if the vehicle is using the air conditioning function, the display device displays the temperature, wind power, and the like set by the air conditioner at that time. When the display device detects the touch operation occurring in the display area AA, the corresponding function key C is displayed at the position where the touch operation occurs. It should be noted that the display device of the present embodiment includes a display area AA and a non-display area NA, and the touch operation detected by the display device is a touch operation occurring within the display area AA of the display device.
In the feedback method of the display device of this embodiment, in the safety mode, when the display device detects a touch operation occurring in the display area AA of the display device, the corresponding function key C is displayed at a position where the touch operation occurs, that is, in the driving mode, when a user needs to touch the function key C of the vehicle infotainment system to perform function selection, the user can call the function key C by touching any position of the display area AA of the display device, and optionally, the position where the function key C occurs is a position touched by a finger in the display area AA.
By the display device provided by the embodiment of the invention, the display device comprises a safe mode, in the safe mode, the function key C is not fixed at one position any more, and when a user does not need the function key C, the function key C cannot appear, the display area AA cannot be occupied, and the picture can be displayed more completely; under the condition that the user needs to pay attention to watch the screen, clearer information is provided for the user, interference of the function key C is avoided, and the user can find the content which the user wants to watch more quickly. In addition, when a user needs to touch the display device, the user does not need to look at the display device to find the function key C, but touches any position of the display area AA, the function key C can appear at the touch position, and the position of the user finger does not need to be adjusted. By the method and the device, the operation on the display device can be more efficient and quicker, the time for the user to touch and search the functional key C is reduced, and the user does not need to pay attention to search the functional key C, so that the driving safety is improved. Meanwhile, the function key C is displayed only when the user performs touch operation, so that the number of physical keys of the display device can be reduced, and the interior decoration is more concise and attractive.

Namely, after the user performs touch operation at any position of the display area AA of the display device, the corresponding function key C is displayed at the position of the touch operation, and the user distinguishes and identifies the function key through different vibration frequencies or different sound feedbacks given by the display device.
It should be noted that, in this embodiment, the specific feedback of different types of feedback that at least part of different function keys C correspond to different vibrations or/and sounds is not limited, and the feedback may be a feedback that a name of a different function key C is broadcasted by a voice, or may be a feedback that a vibration frequency is different, or may be a feedback in other manners, and it is only necessary that a user can identify and distinguish different function keys C.
In some optional embodiments, after the display device detects that the touch operation is finished, the display device does not display the corresponding function key; the touch control operation comprises a first touch control operation and a second touch control operation which are continuously generated, when the display device detects the first touch control operation, the corresponding function key is displayed at the position where the first touch control operation is generated, and the function key can respond to the second touch control operation.
In this embodiment, it is further limited that after the display device detects that the touch operation is ended, the display device does not display the corresponding function key, and the touch operation is further explained, where the touch operation includes a first touch operation and a second touch operation that occur continuously, where continuously means that a finger performing the touch operation does not leave a touch operation position on the display device or leaves the touch operation position on the display device for no more than H seconds, and H is greater than 0. When the display device detects the first touch operation, the corresponding function key is displayed at the position where the first touch operation occurs, and the displayed function key can respond to the second touch operation, so that the user can perform the next touch operation.
In some optional embodiments, the first touch operation includes touching, and the second touch operation includes any one of pressing or sliding.
The present embodiment further explains the first touch operation and the second touch operation that continuously occur in the above embodiments, so that those skilled in the art understand the present embodiment, that is, the first touch operation may include touch, and the second touch operation may include any one of pressing or sliding, for example, when the display device detects that the display device detects the touch operation occurring in its display area, the display device displays a corresponding function key at the position where the touch operation occurs, and after the function key is displayed, the function key may respond to the pressing operation or the sliding operation of the user.
Of course, in some other alternative embodiments, the difference between the first touch operation and the second touch operation may be embodied as different touch actions, and specifically, the difference may be a difference in finger pressing force, a difference in touch frequency, a difference in finger contact time with the screen, a difference in finger moving direction on the screen, or a different set of the foregoing.
It should be noted that, the embodiment is only to exemplify what kind of actions the first touch operation and the second touch operation are, and other operation actions may also be taken, and only the first touch operation and the second touch operation need to be different actions and the display device can distinguish and detect.
In some optional embodiments, after the display device detects that the touch operation is ended, the function key disappears after the function key is maintained to be displayed for N seconds, and the function key can respond to the touch operation of the user within N seconds of the function key being maintained to be displayed; wherein N is greater than 0.
In this embodiment, it is further limited that after the display device detects that the touch operation is ended, the function key is not immediately disappeared, but disappears after the display is maintained for N seconds, where N is greater than 0; optionally, 0< N <5, which may provide a time for the user to think about the reaction, thereby improving the user satisfaction. And in the N seconds of the function key maintaining display, the function key can respond to the touch operation of the user, namely the user can continue to perform the touch operation on the function key in the time, the function key is not disappeared or faded or failed due to the influence of the user reaction time, so that the user can have sufficient reaction time to link up the next touch action, and the touch accuracy is improved.
In some optional embodiments, please refer to fig. 3, where fig. 3 is a schematic diagram of a feedback method of a display device according to another embodiment of the present invention, in this embodiment, when the display device detects a touch operation, a first active deformation occurs at a position of the display device during the touch operation.
The present embodiment further defines that when the display device detects the touch operation (as shown in part a of fig. 3) occurring in the display area AA, the display device displays the corresponding function button at the position where the touch operation occurs, and is supplemented with the feedback of vibration or/and sound, and the display device generates the first active deformation (as shown in part b of fig. 3) at the position where the touch operation occurs. It should be noted that the first active deformation is not formed by a user performing a touch operation (touching or pressing), but is a deformation of the display device itself. The first active deformation is generated at the position of the touch operation, so that the user can sense the function key at the position of the touch operation more visually and vividly, and the use satisfaction of the user is further improved.
In some optional embodiments, please refer to fig. 4, where fig. 4 is a schematic diagram of a feedback method of a display device according to another embodiment of the present invention, in this embodiment, after the display device detects that the touch operation is finished, the display device returns to be flat at the position of the touch operation.
In this embodiment, when the display device detects a touch operation, the display device generates a first active deformation at the position of the touch operation (as shown in a part a of fig. 4), and after the display device detects that the touch operation is finished, the display device returns to be flat at the position of the touch operation (as shown in a part b of fig. 4).
Please refer to fig. 5, fig. 5 is a schematic diagram of a feedback method of a display device according to another embodiment of the present invention, in which the display device generates a first active deformation at a touch operation position (as shown in part a of fig. 5), and after the display device detects that the touch operation is finished, the display device generates a second active deformation at the touch operation position (as shown in part b of fig. 5), where the first active deformation and the second active deformation are different deformations.
In some alternative embodiments, continuing to refer to fig. 3, 4 and 5, the first active deformation comprises any one of a protrusion or a depression or a corrugation.
In this embodiment, a further explanation is made on the first active deformation generated by the display device, where the first active deformation includes any one of a protrusion, a depression, or a wrinkle, for example, the display device generates a protrusion deformation at a position of a touch operation, and after the display device detects that the touch operation is finished, the display device returns to be flat or generates a depression deformation at the position of the touch operation;
or the display device generates concave deformation at the position of the touch operation, and after the display device detects that the touch operation is finished, the display device restores to be flat or generates convex deformation at the position of the touch operation;
or the display device generates convex deformation at the position of the touch operation, and after the display device detects that the touch operation is finished, the display device recovers to be flat or generates wrinkle deformation at the position of the touch operation.
It should be noted that, this embodiment is only to exemplify the deformation manner of the first active deformation, and may also be other deformation manners, and only needs to satisfy that the deformation manner of the display device at the touch operation position is different when the display device detects the touch operation and after the display device detects the end of the touch operation, and this embodiment is not limited specifically.
In some alternative embodiments, please continue to refer to fig. 4, fig. 5 and fig. 6, fig. 6 is a schematic diagram of a feedback method of a display device according to another embodiment of the present invention, in which the first active deformation includes a protrusion; after the display device detects that the user presses the raised function key, the height of the protrusion is reduced (as shown in part b of fig. 6) or returns to be flat (as shown in part b of fig. 4) or becomes concave (as shown in part b of fig. 5). For a clearer understanding of the above embodiments, the present embodiment illustrates that the display device generates the first active deformation at the position of the touch operation, for example, the first active deformation includes a protrusion, that is, when the display device detects the touch operation, the display device generates the protrusion at the position of the touch operation (that is, the position where the function key appears) corresponding to the appearance of a function key similar to a "button", and after the user further presses the "button", the protrusion height of the "button" may be reduced (as shown in part b of fig. 6) or restored to be flat (as shown in part b of fig. 4) or changed to be concave (as shown in part b of fig. 5), and the user may be reflected that the user operates the function key of the "button" type in different deformation forms, so that the user operation is more intuitive and clearer, and the user experience is improved. Optionally, the deformation degree of the second active deformation is smaller than the deformation degree of the first active deformation.
Specifically, a complete touch operation includes at least a first touch action (hereinafter referred to as a first touch operation) of all touch actions in the complete touch operation. The first touch operation is used to activate the function key, i.e. the function key is displayed at the corresponding touch position of the first touch operation. The first active deformation corresponds to a first touch operation, and a button is provided for a touch action after the first touch operation through the first active deformation. In other words, the first touch operation replaces the step of looking for the function key or button by the user on the display device in the prior art, the user can accurately position the function key position through the first touch operation without paying attention to the display device, and the first active deformation provides feedback and simulates the button, so that the user experience is improved.
The second active deformation corresponds to other touch operations after the first touch action, such as pressing and the like, and the deformation degree of the second active deformation is smaller than that of the first active deformation, so that the 'button' can be simulated more vividly, and the user experience is further improved; the touch screen also has the function of buffering the pressure of the touch action on the screen, and the damage to the area where the first active deformation and the second active deformation occur due to the touch is avoided.
In some optional embodiments, the positions of the touch operation include at least a first touch position and a second touch position that do not overlap; if the function key at the first touch position is not the function key required by the user, the user moves the finger to the second touch position, the display device detects the touch operation at the second touch position at the moment, and the display device displays another function key at the second touch position.
In this embodiment, it is further described that the positions of the touch operation further include a second touch position that is not overlapped with the first touch position, and when the function key displayed at the first touch position is not required by the user after the user performs the touch operation at the first touch position, the user can move a finger to the second touch position, and then the second touch position displays another function key. The position that different function button appear is also different through the position difference that carries out touch operation at every turn in this embodiment to avoid under the function button that appears last time does not have the condition that comes to disappear, another function button appears and causes the demonstration disorder in same position, influences user's normal use, thereby improves user experience.
In some optional embodiments, the location of the touch operation further includes at least a third touch location that does not overlap the first touch location and the second touch location;
if the other function key is still not the function key required by the user, the user continues to perform touch operation by moving the finger to the third touch position, and the operation is circulated until the function key required by the user is obtained.
In this embodiment, it is further described that the positions of the touch operation further include a third touch position that is not overlapped with the first touch position and the second touch position, and when the user continues to perform the touch operation at the second touch position and the function key displayed at the second touch position is still not required by the user, the user may move a finger to the third touch position, and the third touch position displays another function key, so as to loop the operation until the function key required by the user is obtained. The embodiment further enables the positions of different function keys to be different through the different positions of touch operation at each time, so that the situation that the function key appearing at the last time is not ready to disappear is avoided, the phenomenon that the display disorder is caused when another function key appears at the same position, the normal use of a user is influenced, and the user experience and the user satisfaction are further improved.
In some alternative embodiments, the manner of moving the finger includes: stopping sliding after the user slides at least a distance on the screen of the display device; or the user lifts the finger on the screen of the display device to move for a distance and then touches the screen of the display device again.
Specifically, the manner of moving the finger from the first touch position to the second touch position in the present embodiment includes: stopping sliding at a second touch position after the user slides at least a distance from the first touch position on the screen of the display device;
or, after the user lifts the finger on the screen at the first touch position of the display device for a certain distance, the user touches the screen at the second touch position of the display device again.
It should be noted that, the direction and distance of the sliding or moving are not specifically limited in this embodiment, and it is only required that the touch positions after the sliding or moving are still in the display area of the display device and the touch positions are not overlapped with each other.
In some optional embodiments, the location of the touch operation comprises a fourth touch location; if the function key at the fourth touch position is not the function key required by the user, the user performs touch operation again at the fourth touch position, at this time, the display device detects the touch operation again, and the display device displays another function key at the fourth touch position.
In some optional embodiments, if the other function key is still not the function key required by the user, the user continues to perform the touch operation again at the fourth touch position, so as to loop until the function key required by the user is obtained.
