[0026] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the specific implementation methods, methods, steps, structures, features and effects of the touch display panel and touch display device proposed in the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] Figure 1 FIG. 1 is a circuit connection diagram of a touch display panel according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the external structure of a touch display panel according to an embodiment of the present invention. Figure 1 and Figure 2The touch display panel of this embodiment includes at least one trigger module 100, an analog touch layer 210, and a touch display chip 300. The trigger module 100 is disposed in the non-display area 201 of the touch display panel; the analog touch layer 210 is disposed within the touch display panel and located in the display area 202 of the touch display panel; the touch display chip 300 is connected to the trigger module 100 and the analog touch layer 210, respectively. When a trigger module 100 is triggered to generate at least one trigger signal, the touch display chip 300 outputs a corresponding drive signal to the analog touch layer 210 based on the trigger signal. Based on the electric induction effect, the signal level in the corresponding area of the display area 202 changes to simulate a finger touch gesture. The touch display chip 300 determines and processes the corresponding gesture function based on the signal level change in the corresponding area of the display area 202.

[0028] In one embodiment of the present invention, Figure 1 As shown, the simulated touch layer 210 corresponds to multiple areas of the display area 202, and the touch display chip 300 outputs corresponding driving signals according to corresponding trigger signals to control the simulated touch layer 210 to be high level in multiple areas of the display area 202 sequentially or simultaneously to simulate the touch gesture of the finger.

[0029] In one embodiment of the present invention, Figure 1 As shown, the simulated touch layer 210 includes a plurality of regions that divide the display area 202 . Figure 1 In the example, the touch layer divides the display area 202 into 4×2 areas, but the present invention is not limited thereto. For example, the area may be 6×2. The division method of the simulated touch layer 210 is simple, which simplifies the manufacturing and process.

[0030] In one embodiment of the present invention, Figure 1 As shown, the simulated touch layer 210 includes multiple electrode blocks 211 corresponding to the multiple areas divided into the display area 202. The multiple electrode blocks 211 are connected to the touch display chip 300 via multiple channels 310. The touch display chip 300 only needs to occupy a small number of channels 310 to control the simulated touch layer 210 through multiple electrodes to change the signal intensity in the corresponding area to simulate a finger touch gesture.

[0031] In one embodiment of the present invention, the simulated touch layer 210 may be formed into the electrode block 211 by an attachment method or a direct coating method.

[0032] In one embodiment of the present invention, the material of the analog touch layer 210 can be ITO (Indium Tin Oxide). ITO is a commonly used transparent electrode material, so that the analog touch layer 210 only slightly sacrifices the backlight brightness and does not affect the front display effect of the touch display panel.

[0033] In one embodiment of the present invention, the trigger module 100 is a mechanical button or a touch button.

[0034] For details, please also refer to Figure 1 and Figure 2 The touch display panel of this embodiment includes at least one trigger module 100, an analog touch layer 210, and a touch display chip 300. An example of a touch display panel is an incell touch display panel. The touch display chip 300 can drive the display and touch control of the touch display panel. The trigger module 100, such as a mechanical button, is disposed in the non-display area 201 of the touch display panel, for example, below the display area 202. When a trigger module 100 generates at least one trigger signal, the touch display chip 300 outputs a corresponding drive signal, such as a pulse level, to the multiple electrode blocks 211 in the corresponding area of the simulated touch layer 210 based on the trigger signal. This triggers the electro-inductive effect, causing the signal level in the corresponding area of the display area 202 to change, simulating a finger touch gesture. The touch sensing layer 230 can detect signal level changes in all areas of the display area 202, and can detect signal level changes in the corresponding area caused by a finger touch gesture on the panel surface, as well as signal level changes in the corresponding area caused by a simulated finger touch gesture on the simulated touch layer 210. Based on the signal level changes in the corresponding area of the display area 202, the touch display chip 300 determines and processes the corresponding gesture function, such as turning on or off or adjusting the corresponding electronic device. This allows users to perform touch gesture operations on the panel and conveniently activate gesture functions through the trigger device even when not performing touch gesture operations on the panel, thus improving the user experience.

[0035] In one embodiment of the present invention, when the touch display chip 300 receives a trigger signal, it switches the size of the touch resolution to be used to identify the touch gestures of the simulated finger of the simulated touch layer 210. Specifically, when the touch display chip 300 does not receive a trigger signal, that is, when the trigger module 100 is not triggered, the touch resolution size of the touch display chip 300 is set to 2.5cmX2.5cm, which can be used to identify the touch gestures of the fingers on the panel surface. A touch larger than 2.5cmX2.5cm can be defined as a palm touch, that is, it is not recognized as a gesture and the gesture function is not triggered. When the touch display chip 300 receives a trigger signal, that is, when the trigger module 100 is triggered, the touch display chip 300 switches the size of the touch resolution to 5cmX5cm, which can be used to identify the touch gestures of the simulated finger that touches a large area of the simulated touch layer 210, which can be more conducive to the recognition of the touch gestures of the simulated finger.

[0036] Figure 3 FIG. 1 is a schematic diagram of the internal structure of a touch display panel according to an embodiment of the present invention.

[0037] In one embodiment of the present invention, Figure 3 As shown, the simulated touch layer 210 is disposed on a side of the touch sensing layer 230 away from the panel surface.

[0038] In one embodiment of the present invention, Figure 3 As shown, the distance from the simulated touch layer 210 to the touch sensing layer 230 is substantially equal to the distance from the touch sensing layer 230 to the panel surface.

[0039] Specifically, if Figure 3 As shown, the touch display panel may include, in sequence, a backlight layer 220, an analog touch layer 210, a touch sensing layer 230, and a protective glass layer 240. The outer surface of the protective glass layer 240 is the panel surface. Thus, the touch sensing layer 230 can be used not only to sense changes in signal intensity caused by a finger touching the panel surface, but also to sense changes in signal intensity caused by simulated finger touch on the analog touch layer 210. This allows the touch display panel to exhibit excellent double-sided capacitive sensing effects. Furthermore, the distance from the analog touch layer 210 to the touch sensing layer 230 can be set to be approximately equal to the distance from the touch sensing layer 230 to the panel surface, further enhancing the touch display panel's double-sided capacitive sensing effects.

[0040] In one embodiment of the present invention, the triggering mode of the trigger module 100 includes at least one of pressing, left rotation and right rotation, but the present invention is not limited thereto and other triggering modes may also be used.

[0041] In one embodiment of the present invention, the touch gesture of the finger includes at least one of clicking, sliding, and rotating, but the present invention is not limited thereto, and other touch gestures may also be used.

[0042] It should be noted that the present invention does not limit the correspondence between the triggering mode of the trigger module 100 and the finger touch gesture, nor does it limit the correspondence between the finger touch gesture and the gesture function. The touch display chip 300 can pre-edit and store. The following is only an example of an embodiment.

[0043] like Figure 4 As shown, Figure 4 This is a schematic diagram of a first touch control method for a touch display panel according to an embodiment of the present invention. When a finger presses a trigger module 100, such as an air conditioner button, the channel 310 of the touch display chip 300 can output a driving signal, such as a corresponding voltage level, to control the change in the signal level of the simulated touch layer 210 in a corresponding area (such as the area indicated by the yellow arrow) through the corresponding multiple electrode blocks 211, simulating a finger touch gesture such as a click. The touch display chip 300 can detect the change in the signal level in the area (such as the area indicated by the yellow arrow) through the touch sensing layer 230, and determine and process the corresponding gesture function, such as turning on the air conditioner.

[0044] like Figure 5 As shown, Figure 5This is a schematic diagram of a second touch method for a touch display panel according to an embodiment of the present invention. When a finger rotates a trigger module 100, such as an air conditioner button, to the left, the channel 310 of the touch display chip 300 can output a driving signal, such as a corresponding electrical level, to control the change in the signal level of the simulated touch layer 210 in a corresponding area (such as the area indicated by the blue arrow) through the corresponding multiple electrode blocks 211, simulating a finger touch gesture such as sliding. The touch display chip 300 can detect the change in the signal level in the area (such as the area indicated by the blue arrow) through the touch sensing layer 230, and determine and process the corresponding gesture function, such as adjusting the air conditioner temperature.

[0045] like Figure 6 As shown, Figure 6 This is a schematic diagram of a third touch method for a touch display panel according to an embodiment of the present invention. When a finger rotates a trigger module 100, such as an air conditioner button, to the right, the channel 310 of the touch display chip 300 can output a drive signal, such as a corresponding voltage level, to control the change in the signal level of the simulated touch layer 210 in a corresponding area (such as the area indicated by the red arrow) through the corresponding multiple electrode blocks 211, simulating a touch gesture such as rotation. The touch display chip 300 can detect the change in the signal level in the area (such as the area indicated by the red arrow) based on the touch sensing layer 230, and determine and process the corresponding gesture function, such as adjusting the air volume of the air conditioner.

[0046] like Figure 7 As shown, Figure 7 This is a schematic diagram of a fourth touch method for a touch display panel according to an embodiment of the present invention. When a finger presses a trigger module 100, such as an air conditioner button, again, the channel 310 of the touch display chip 300 can output a drive signal, such as a corresponding voltage level, to control the change in the signal level of the simulated touch layer 210 in a corresponding area (such as the area indicated by the purple arrow) through the corresponding multiple electrode blocks 211, simulating a finger touch gesture such as a click. The touch display chip 300 can detect the change in the signal level in the area (such as the area indicated by the purple arrow) through the touch sensing layer 230, and determine and process the corresponding gesture function, such as turning off the air conditioner.

[0047] Based on the same inventive concept, an embodiment of the present invention further provides a touch display device, which includes the touch display panel provided in the above embodiment. The implementation of the touch display device can refer to the above embodiment of the touch display panel, and the repeated parts will not be repeated.

[0048] The embodiments of the present application do not impose any specific restrictions on the applicability of the above-mentioned touch display device. It can be a display device with touch function such as a terminal device (smartphone, tablet computer, automatic terminal, etc.), a vehicle-mounted device (vehicle-mounted terminal, navigation system, assisted reversing system, driving recorder, vehicle-mounted refrigerator, etc.), and there is no restriction here.

[0049] The touch display panel and touch display device of the present invention include at least one trigger module 100, an analog touch layer 210, and a touch display chip 300. The trigger module 100 is disposed in the non-display area 201 of the touch display panel; the analog touch layer 210 is disposed within the touch display panel and located in the display area 202 of the touch display panel; and the touch display chip 300 is connected to the trigger module 100 and the analog touch layer 210, respectively. When a trigger module 100 generates at least one trigger signal, the touch display chip 300 outputs a corresponding drive signal to the analog touch layer 210 based on the trigger signal. This causes the signal level in the corresponding area of the display area 202 to change due to the electro-inductive effect, simulating a finger touch gesture. The touch display chip 300 then determines and processes the corresponding gesture function based on the signal level change in the corresponding area of the display area 202. Thus, the present invention enables users to conveniently activate gesture functions through the trigger device even when not performing touch gesture operations on the panel, thereby improving the user experience.

[0050] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the technical contents disclosed above without departing from the scope of the technical solution of the invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the invention without departing from the content of the technical solution of the invention are still within the scope of the technical solution of the present invention.
