Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a touch display device, it should be noted that the steps shown in the flowchart of the drawings may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown.
Fig. 1 is a schematic diagram of an alternative touch display device according to an embodiment of the present invention, as shown in fig. 1, the touch display device includes:
the infrared emission lamp matrix 100 is arranged on a first side of a display area 300 of the touch display device, and the length of the infrared emission lamp matrix 100 is smaller than the side length of the first side;
the infrared receiving lamp matrix 200 is disposed on a second side of the display area 300, a length of the infrared receiving lamp matrix 200 is smaller than a side length of the second side, the first side and the second side are adjacent sides, and an induction area 400 for inducing touch operation is formed between the infrared emitting lamp matrix 100 and the infrared receiving lamp matrix 200.
The infrared emission lamp matrix 100 is provided with a plurality of emission lamps, the infrared reception lamp matrix 200 is provided with a plurality of reception lamps, the emission lamps are used for emitting infrared rays, the reception lamps are used for receiving the infrared rays emitted by the emission lamps, and the emission lamps emit the infrared rays to the reception lamps at the same time, so that an infrared detection network with crossed infrared rays is formed between the infrared emission lamp matrix 100 and the infrared reception lamp matrix 200, and the area covered by the infrared detection network is the induction area 400. When a user touches the display area 300 of the touch display device with a finger or other object in the sensing area 400, the infrared ray at the touch position is blocked, so that the main control unit 500 can identify the touch position of the user based on the blocked infrared ray.
Optionally, in this embodiment, the touch display device includes a display screen, a screen area of the display screen is the display area 300, and the display area 300 may be a rectangle or a polygon. The matrix of ir-emitting lamps 100 is disposed at a first side of the display area 300 and the matrix of ir-receiving lamps 200 is disposed at a second side of the display area 300. Preferably, the matrix of ir-emitting lamps 100 and the matrix of ir-receiving lamps 200 are located at the same plane. Wherein the first edge is any edge on the display area 300, the second edge is an edge adjacent to the first edge, and the infrared emitting lamp matrix 100 may be disposed at any position on the first edge, and the infrared receiving lamp matrix 200 may be disposed at any position on the second edge, i.e., the infrared emitting lamp matrix 100 and the infrared receiving lamp matrix 200 may not be in contact, preferably, the infrared emitting lamp matrix 100 and the infrared emitting lamp matrix 200 are disposed at corner areas of the display area 300, i.e., edges where there is mutual contact between the infrared emitting lamp matrix 100 and the infrared emitting lamp matrix 200, wherein the corner areas of the display area 300 may be acute-angle areas, obtuse-angle areas, or right-angle areas of the display area, and preferably are right-angle areas. Since the length of the ir emitting lamp matrix 100 is less than the length of the first side and the length of the ir receiving lamp matrix 200 is less than the length of the second side, the sensing area 400 is smaller than the display area 300. It should be noted that the sensing area 400 is at least larger than the touch area required by the manufacturer (i.e. the function requiring area 600) or the touch area desired by the user.
It should be noted that by disposing the ir-emitting lamp matrix 100 and the ir-receiving lamp matrix 200 on the adjacent sides of the display area 300, respectively, an effective sensing area 400 can be formed between the ir-emitting lamp matrix 100 and the ir-receiving lamp matrix 200. Furthermore, by setting the infrared emitting lamp matrix 100 with a length smaller than the side length of the first edge and the infrared receiving lamp matrix 200 with a length smaller than the side length of the second edge, the cost required by the touch display device to realize the touch function can be effectively reduced.
And a main control unit 500 respectively connected to the ir transmitting lamp matrix 100 and the ir receiving lamp matrix 200, for controlling the display content of the display area 300 based on the sensing area 400.
The main control unit 500 is disposed in the touch display device and connected to the display screen, the main control unit 500 may be directly connected to the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200, that is, directly acquire signals transmitted by the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 to identify a touch position of a user, or indirectly connected to the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 through the processing module, the processing module acquires signals transmitted by the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 and transmits the signals to the main control unit 500, and the main control unit 500 identifies the touch position of the user.
Optionally, the main control unit 500 may correspond the first area in the sensing area 400 to the display area 300, that is, any position of the display area 300 may find a corresponding touch point in the first area, so as to implement a click on each position of the display area 300, where the first area may be a partial area in the sensing area 400 or may be a whole area of the sensing area 400. For example, if the display area 300 is rectangular, the first area may be a rectangle in equal proportion to the display area 300, and when the user touches the upper right corner of the first area, the main control unit 500 recognizes the touch position of the user and corresponds the touch position to the upper right corner of the display area 300; when the user touches the center position of the first area, the main control unit 500 recognizes the touch position of the user and corresponds the position to the center position of the display area 300. The main control unit 500 determines the operation type (e.g., selecting, deselecting, etc.) that the user desires to implement at the corresponding position of the display area 300 by recognizing other touch operations of the user, so as to display or adjust the corresponding display content in the display area 300, thereby achieving the effect of controlling the display content of the large-scale display area 300 based on the small-scale sensing area 400. It should be noted that the main control unit 500 may be configured to control the display screen to zoom and display the same content as the display content of the display area 300 at a position corresponding to the aforementioned position of the first area, so as to facilitate the user to determine the touch position.
Optionally, the main control unit 500 may also determine a stroking operation of the user during the touch process based on the identified touch position of the user, and enlarge the stroking distance along the stroking direction according to a preset scale, so that the user can move a cursor or other pointing sign to any position of the display area 300 in a stroking touch manner in the first area. The main control unit 500 may then determine the operation type (e.g., selecting, deselecting, etc.) that the user desires to implement at the corresponding position of the display area 300 by recognizing other touch operations of the user, thereby achieving an effect of controlling the display content of the large-scale display area 300 based on the small-scale sensing area 400.
Optionally, the main control unit 500 may further control the display screen to display a touch function block at a position corresponding to the position of the first area, and determine a touch function block that the user wants to click on based on the identified touch position of the user, where the touch function block is used to control at least one content displayed in the display area 300, so as to achieve an effect of controlling the large-range display area 300 based on the small-range sensing area 400.
It should be noted that, the main control unit 500 controls the display content of the display area 300 based on the sensing area 400, so as to avoid that when the number of the infrared emitting lamp matrix 100 and the number of the infrared receiving lamp matrix 200 are reduced, the sensing area 400 cannot cover the display area, which causes that a part of the display area exists and cannot be controlled, thereby ensuring the normal operation of the touch display device.
In the prior art, a touch requirement of a part of large-sized screens is that a touch feedback function is required for the full screen, a related touch display device covers a touch function (i.e. covers the sensing area 400) for the whole display area of the screen to realize the control of the display area, meanwhile, as shown in fig. 2, a touch requirement of a part of large-sized screens is that a touch feedback function is required for the screen area (i.e. the function requiring area 600), and a related touch display device also covers a touch function (i.e. covers the sensing area 400) for the whole display area of the screen. Therefore, for the two touch requirements of the large-size screen, as shown in fig. 2, the ir-emitting lamp matrix 100 and the ir-receiving lamp matrix 200 are distributed on four sides of the display area 300, which results in a problem of high touch cost.
Based on the scheme that each above-mentioned unit or module was prescribed a limit to, can learn, in the embodiment of the utility model, the mode of the display content of the display area 300 on a relatively large scale is controlled based on the response area 400 of relatively narrow range is adopted, through setting up infrared emission lamp matrix 100, and set up it on the first side of the display area 300 of touch display device, set up infrared receiving lamp matrix 200, and set up it on the second side of display area 300, set up main control unit 500, and link to each other it with infrared emission lamp matrix 100 and infrared receiving lamp matrix 200 respectively, in order to control the display content of display area 300 based on response area 400. The length of the infrared emitting lamp matrix 100 is smaller than the side length of the first side, the length of the infrared receiving lamp matrix 200 is smaller than the side length of the second side, the first side and the second side are adjacent sides, and an induction area 400 for inducing touch operation is formed between the infrared emitting lamp matrix 100 and the infrared receiving lamp matrix 200.
It is easy to note that, in the above units or modules, by setting the infrared emitting lamp matrix 100 with a length less than the side length of the first side and the infrared receiving lamp matrix 200 with a length less than the side length of the second side, the cost required by the touch display device to implement the touch function can be effectively reduced, and by setting the main control unit 500 to control the display content of the display area 300 based on the sensing area 400, it is avoided that when the infrared emitting lamp matrix 100 and the infrared receiving lamp matrix 200 are reduced, the display content of a partial area of the display area cannot be controlled due to the sensing area 400 not covering the display area, so that the normal operation of the touch display device is ensured while the touch cost is reduced. Further, by disposing the ir-emitting lamp matrix 100 and the ir-receiving lamp matrix 200 on adjacent sides of the display area 300, respectively, an effective sensing area 400 can be formed between the ir-emitting lamp matrix 100 and the ir-receiving lamp matrix 200.
Therefore, the scheme provided by the application achieves the purpose of controlling the display content of the display area 300 in a relatively large range based on the sensing area 400 in a relatively small range, so that the technical effect of reducing the touch cost is achieved, and the technical problem of high touch cost of the touch display device caused by the complex structure of the touch screen in the prior art is solved.
In an alternative embodiment, the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 are disposed in a first area of the touch display device, wherein the first area is an area outside the display area 300 on the touch display device. The plane of the sensing area 400 is located between the touch-control party and the plane of the display area 300, and the projection of the sensing area 400 on the plane of the display area 300 has an overlapping area with the display area 300, so that the touch-control party always touches the sensing area 400 first when the touch-control party wants to touch the display area 300, and the main control unit 500 can always identify the touch-control position of the touch-control party. Preferably, the overlapping area of the projection of the sensing area 400 on the plane of the display area 300 and the display area 300 is located in a relatively lower area of the display area 300, so as to facilitate the touch control of the user and improve the user experience.
It should be noted that, by arranging the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 outside the display area 300, the shielding of the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 on the display area 300 is avoided, so as to improve the user experience.
In an alternative embodiment, the first edge is perpendicular to the second edge; the infrared transmitting lamp matrix 100 is attached to the first side, and the infrared receiving lamp matrix 200 is attached to the second side.
Optionally, in this embodiment, the display area is rectangular, the infrared emission lamp matrix 100 is attached to the first side, and the infrared reception lamp matrix 200 is attached to the second side, that is, the infrared emission lamp matrix 100 is perpendicular to the infrared reception lamp matrix 200, so that the infrared emission lamp matrix 100 and the infrared reception lamp matrix 200 are conveniently mounted, and the main control unit 500 is adapted to the infrared emission lamp matrix 100 and the infrared reception lamp matrix 200.
In an alternative embodiment, the end surface of one end of the infrared transmitting lamp matrix 100 and the side surface of one side of the infrared receiving lamp matrix 200 are located on the same plane, and the end surface contacts with the side surface.
Optionally, the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 are both of a rectangular parallelepiped structure or an approximate rectangular parallelepiped structure, and the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 respectively have two end faces and four side faces. In this embodiment, as shown in fig. 3, an end surface of one end of the ir-emitting lamp matrix 100 and a side surface of one side of the ir-receiving lamp matrix 200 are located on the same plane, and the end surface of the ir-emitting lamp matrix 100 contacts with the side surface of the ir-receiving lamp matrix 200, that is, the ir-emitting lamp matrix 100 and the ir-receiving lamp matrix 200 are disposed at a right angle of the display area, the sensing area 400 formed by the ir-emitting lamp matrix 100 and the ir-receiving lamp matrix 200 is a right triangle, a right-angle side of the sensing area 400 coincides with a right-angle side of the display area 300, and the sensing area 400 at least covers the function requiring area 600.
In an alternative embodiment, the end surface of one end of the infrared transmitting lamp matrix 100 is located on the same plane as the side surface of one side of the infrared receiving lamp matrix 200, and one edge of the end surface is in contact with one edge of the side surface.
Preferably, as shown in FIG. 3, one side of the end surface adjacent to the matrix of IR receiving lamps 200 is in contact with one side of the side surface adjacent to the matrix of IR emitting lamps 100.
It should be noted that, by arranging the infrared emitting lamp matrix 100 and the infrared receiving lamp matrix 200 at the right angle of the display area 300, that is, forming the optical network coverage at the right angle of the display area 300, the actual use requirements of the user can be better met, and further, the user experience is improved. Meanwhile, since the aforementioned display screen may be composed of a plurality of display units, that is, a plurality of small display screens, when the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 are randomly arranged on two sides of the display area 300, the sensing area 400 formed by the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 may cover the plurality of small display screens, that is, the main control unit 500 needs to control the plurality of small display screens to display corresponding touch function blocks or other display contents, and when the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 are arranged at a right angle to the display area 300, the sensing area 400 formed by the main control unit 500 may correspond to a single small display screen exactly, that is, the main control unit 500 only needs to control the single small display screen to display corresponding touch function blocks or other display contents, so as to better control the display contents of the relatively large-range display area 300 based on the sensing area 400 which is relatively small in touch range.
In an alternative embodiment, a plurality of emission lamps are disposed on the infrared emission lamp matrix 100, and the arrangement density of the emission lamps disposed at both ends of the infrared emission lamp matrix 100 is greater than that of the emission lamps disposed at the middle portion of the infrared emission lamp matrix 100. Both ends of the infrared emission lamp matrix 100 and the middle portion of the infrared emission lamp matrix 100 are used for representing the range.
Specifically, on the infrared emission lamp matrix 100, the arrangement density of the emission lamps closer to the end points of the infrared emission lamp matrix 100 is relatively higher, and the arrangement density of the emission lamps relatively far away from the end points of the infrared emission lamp matrix 100 (i.e., the emission lamps are arranged in the middle of the infrared emission lamp matrix 100) is relatively lower, optionally, the arrangement density of the emission lamps in the preset length range at the two ends of the infrared emission lamp matrix 100 may also be set to be the first density, the arrangement density of the emission lamps in the preset length range at the middle of the infrared emission lamp matrix 100 may also be set to be the second density, and the first density is greater than the second density. Therefore, the phenomenon that the infrared detection net in the middle part is dense and the infrared optical net in the edge part is loose in the formed sensing area 400 when the arrangement density of all the emission lamps on the infrared emission lamp matrix 100 is the same can be avoided, and the sensing effect of the edge part of the sensing area is further effectively improved.
In an alternative embodiment, a plurality of receiving lamps are disposed on the infrared receiving lamp matrix 200, and the arrangement density of the emitting lamps disposed at both ends of the infrared emitting lamp matrix 100 is greater than that of the emitting lamps disposed at the middle portion of the infrared emitting lamp matrix 100. Both ends of the infrared receiving lamp matrix 200 and the middle portion of the infrared receiving lamp matrix 200 are used for representing the range.
Specifically, on the infrared receiving lamp matrix 200, the arrangement density of the receiving lamps at the end points closer to the infrared receiving lamp matrix 200 is relatively higher, while the arrangement density of the receiving lamps at the end points relatively far from the infrared receiving lamp matrix 200 (i.e., the receiving lamps arranged at the middle part of the infrared transmitting lamp matrix 100) is relatively lower, alternatively, the arrangement density of the receiving lamps in the preset length range at the two ends of the infrared receiving lamp matrix 200 may be set to a third density, the arrangement density of the receiving lamps in the preset length range at the middle part of the infrared receiving lamp matrix 200 may be set to a fourth density, and the third density is greater than the fourth density. Therefore, the phenomenon that the infrared detection net in the middle part of the formed sensing area 400 is dense and the infrared light net in the edge part of the formed sensing area 400 is loose when the arrangement density of the receiving lamps in each part of the infrared receiving lamp matrix 200 is the same can be avoided, and the sensing effect of the edge part of the sensing area is further effectively improved.
In an alternative embodiment, the signal emitted by each of the transmitting lamps is received by at least one of the plurality of receiving lamps.
Alternatively, the signal emitted by each emitting lamp may be received by a part of the receiving lamps in the infrared receiving lamp matrix 200, or may be received by all the receiving lamps in the infrared receiving lamp matrix 200. Thereby, a dense optical network may be formed so that the main control unit 500 recognizes the touch points and improves the recognition accuracy of the main control unit 500.
In an alternative embodiment, the matrix of IR emitting lamps 100 is removably positioned on the first side.
Optionally, a sliding groove may be formed on one side of the first edge, the ir-emitting lamp matrix 100 is slidably disposed in the sliding groove, and is fixed by a bolt, so that the ir-emitting lamp matrix 100 is movably disposed on the first edge. Therefore, the relative positions of the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 can be changed, so that the size and the shape of the formed sensing area 400 are changed, and the applicability of the application is further improved.
In an alternative embodiment, the infrared receiver lamp matrix 200 is removably disposed on the second side.
Optionally, a sliding groove may be disposed on one side of the second edge, the infrared receiving lamp matrix 200 is slidably disposed in the sliding groove, and is fixed by a bolt, so that the infrared receiving lamp matrix 200 is movably disposed on the second edge. Therefore, the relative positions of the infrared transmitting lamp matrix 100 and the infrared receiving lamp matrix 200 can be changed, so that the size and the shape of the formed sensing area 400 are changed, and the applicability of the application is improved.
