[0078] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure.

"First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0080] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual proportions, and are only intended to illustrate the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0081] The present disclosure provides a tactile feedback display device, such as Figure 1 As shown, including:

[0082] A first circuit board 100;

[0083] The adapter connector 200 is fixedly disposed on the first circuit board 100 and electrically connected to the first circuit board 100;

[0084] The functional circuit assembly 300 is installed on the adapter connector 200 in a plug-in manner and is electrically connected to the first circuit board 100 via the adapter connector 200 .

[0085] The tactile feedback display device provided by the embodiment of the present disclosure, by setting an adapter connector on the first circuit board, when the functional circuit component needs to be connected to the first circuit board, the functional circuit component can be installed on the functional circuit component by plugging, so that the functional circuit component is connected to the wiring in the first circuit board through the adapter connector to perform signal transmission. When the functional circuit component needs to be replaced, the original functional circuit component can be removed from the adapter connector, and the new functional circuit component can be installed on the functional circuit component by plugging, so as to achieve the replacement of functional circuit components of different specifications, so that it can be suitable for tactile feedback display devices with different driving requirements, thereby reducing development costs and shortening development cycles.

[0086] Exemplarily, the adapter connector may be fixed on the first circuit board by soldering or the like, which is not limited here. The adapter connector may include a surface mount technology (SMT) connector, a dual in-line package (DIP) connector, etc., which is not limited here.

[0087] Exemplarily, the functional circuit components in the tactile feedback display device generally include: a power input circuit, a voltage conversion circuit, a processing control circuit, a low-voltage signal input circuit, a first high-voltage amplifier circuit, a storage circuit, and a display driver circuit. Among them, the power input circuit is used to provide a power supply voltage, directly supplying power to the voltage conversion circuit and the first high-voltage amplifier circuit. The voltage conversion circuit is used to convert the power supply voltage into a target voltage and then supply power to the processing control circuit, the low-voltage signal input circuit, the storage circuit, and the display driver circuit. The processing control circuit is used to output a control signal to control the voltage conversion circuit, the low-voltage signal input circuit, the first high-voltage amplifier circuit, the storage circuit, and the display driver circuit to work. The low-voltage signal input circuit is used to generate a low-voltage signal and transmit it to the first high-voltage amplifier circuit. The first high-voltage amplifier circuit is used to amplify the low-voltage signal into a first high-voltage signal. The storage circuit is used to store information required by the processing control circuit. The display driver circuit is used to control the display panel to display the picture.

[0088] In some embodiments of the present disclosure, Figure 1 and 2 As shown, the functional circuit assembly 300 includes: a power input circuit 310, which is configured to provide a power supply voltage. The adapter connector 200 includes: a first adapter connector 210. The power input circuit 310 is electrically connected to the first circuit board 100 through the first adapter connector 210.

[0089] In some embodiments of the present disclosure, Figure 2 and Figure 3As shown, the power input circuit 310 includes: a first pin 1, a second pin 2, a third pin 3, a fourth pin 4, and a fifth pin 5. The first adapter connector 210 includes: a first port 01, a second port 02, a third port 03, a fourth port 04, and a fifth port 05. Among them, the first pin 1 and the second pin 2 are configured to be grounded; the third pin 3 is configured to be electrically connected to the negative high voltage signal terminal on the first circuit board 100; the fourth pin 4 is configured to be electrically connected to the positive high voltage signal terminal on the first circuit board 100; the fifth pin 5 is configured to be electrically connected to the low voltage signal terminal on the first circuit board 100; among them, the first port 01 is electrically connected to the first pin 1, the second port 02 is electrically connected to the second pin 2, the third port 03 is electrically connected to the third pin 3, the fourth port 04 is electrically connected to the fourth pin 4, and the fifth port 05 is electrically connected to the fifth pin 2.

[0090] Exemplarily, the power supply voltage provided by the power input circuit includes a positive high voltage signal, a negative high voltage signal and a low voltage signal, so as to power the tactile feedback display device. The power input circuit is installed on the first adapter connector by cable connection. The tactile feedback display device with different driving requirements can use power input circuits of different specifications. For example, when the power supply voltage provided by the power input circuit installed on the first adapter connector cannot meet the power supply requirements of the tactile feedback display device, the power input circuit can be removed from the first adapter connector. At this time, the power input circuit needs to be replaced with a new power input circuit that can meet the power supply requirements of the tactile feedback display device.

[0091] Furthermore, since the power input circuit directly supplies power to the first high-voltage amplifier circuit through the wiring on the first circuit board, the magnitude and power of the power voltage provided by the power input circuit determine the voltage value and output power value of the first high-voltage signal output by the first high-voltage amplifier circuit. The first adapter connector can pass a relatively large current, for example, the maximum current that can pass includes 5A, and of course, other currents can also pass, which can be set according to demand and is not limited here.

[0092] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the functional circuit assembly 300 includes: a voltage conversion circuit 320, which is configured to convert the power supply voltage into a target voltage. The adapter connector 200 includes: a second adapter connector 220. The voltage conversion circuit 320 is electrically connected to the first circuit board 100 through the second adapter connector 220.

[0093] In some embodiments of the present disclosure, Figure 2 and Figure 4As shown, the voltage conversion circuit 320 also includes: a sixth pin 6, a seventh pin 7, an eighth pin 8, and a ninth pin 9; the second adapter connector 220 also includes: a sixth port 06, a seventh port 07, an eighth port 08, and a ninth port 09; the sixth pin 6 and the seventh pin 7 are configured to be grounded; the eighth pin 8 is configured to be electrically connected to the fourth pin 4; the ninth pin 9 is configured to be electrically connected to the fifth pin 5; wherein, the sixth port 06 is electrically connected to the sixth pin 6, the seventh port 07 is electrically connected to the seventh pin 7, the eighth port 08 is electrically connected to the eighth pin 8, and the ninth port 09 is electrically connected to the ninth pin 9.

[0094] Exemplarily, the voltage conversion circuit is installed on the second adapter connector in a plug-in manner. The voltage conversion circuit can convert the power supply voltage provided by the power input circuit into a target voltage (e.g., 12V), and the target voltage (e.g., 12V) is input into the processing control circuit, the low-voltage signal input circuit, the storage circuit, and the display drive circuit, and the processing control circuit, the low-voltage signal input circuit, the storage circuit, and the display drive circuit are powered. In addition, since the processing control circuit, the low-voltage signal input circuit, the storage circuit, and the display drive circuit are all powered by the voltage conversion circuit, the problem that the power supply voltage input by the power input circuit changes, resulting in the subsequent other circuits not being able to work normally, can be effectively avoided. Since the power supply voltage that enables the voltage conversion circuit to work normally has a certain range, when the range of the power supply voltage changes, an adaptive voltage conversion circuit can be selected to ensure the output of the subsequent target voltage (e.g., 12V). For example, if the power supply voltage is currently V1, the current voltage conversion circuit installed on the second adapter connector can convert V1 into the target voltage. If the power supply voltage increases to V2, the current voltage conversion circuit installed on the second adapter connector cannot support the conversion of V2. At this time, the current voltage conversion circuit needs to be replaced with a new voltage conversion circuit that can support the conversion of V2. The current voltage conversion circuit can be removed from the second adapter connector and the new voltage conversion circuit can be installed on the second adapter connector, so that the new voltage conversion circuit can be used to convert V2 into the target voltage.

[0095] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the functional circuit assembly 300 includes: a processing control circuit 330, and the processing control circuit 330 is configured to output a control signal. The adapter connector 200 includes: a third adapter connector 230. The processing control circuit 330 is electrically connected to the first circuit board 100 through the third adapter connector 230.

[0096] In some embodiments of the present disclosure, the processing control circuit includes at least n pins; the third adapter connector includes at least n ports; the n pins are electrically connected to the n ports in a one-to-one correspondence; wherein x pins out of the n pins are configured to be electrically connected to the control signal terminal on the first circuit board; y pins out of the n pins are configured to be grounded; z pins out of the n pins are configured to be electrically connected to the ninth pin; n=x+y+z, n is greater than or equal to 480, x is greater than or equal to 376, y is greater than or equal to 96, and z is greater than or equal to 8.

[0097] Exemplarily, the processing control circuit is installed on the third adapter connector in a plug-in manner. For a tactile feedback display device with complex calculations and requiring a mounting system, a processing control circuit with a microprocessor (Advanced RISC Machine, ARM) core can be used. For a tactile feedback display device that does not require a mounting system and has simple calculations, a processing control circuit without a microprocessor (Advanced RISC Machine, ARM) core can be used, thereby reducing costs.

[0098] For example, Figure 5 As shown, the third adapter connector is composed of 4 third sub-adapter connectors 231, 232, 233, and 234, wherein each third sub-adapter connector has 120 ports, and each 5 ports form a port group, then each third sub-adapter connector has 24 port groups, and one port in each port group is configured to be grounded. Among them, 2 port groups in the third sub-adapter connector 232 are used to input the target voltage (for example, 5V) to power the processing control circuit, and the other unmentioned ports are configured to provide control signals at the control signal end. The positions of the third sub-adapter connectors 231, 232, 233, and 234 are shown in FIG. Figure 5 As shown, the third sub-adapter connectors 231, 232 are not centered, but are moved down a certain distance to avoid the processing control circuit being burned out due to reverse insertion. Of course, the third sub-adapter connectors 231, 232 can also be moved up a certain distance as long as they are not centered, and this is not limited here.

[0099] In some embodiments of the present disclosure, Figure 1 and 2 As shown, the functional circuit component 300 includes: a first high-voltage amplifier circuit 340, which is configured to output a first high-voltage signal; the adapter connector 200 includes: a fourth adapter connector 240; the first high-voltage amplifier circuit 340 is electrically connected to the first circuit board 100 through the fourth adapter connector 240.

[0125] Alternatively, if Figure 8a As shown, the multiple tactile detection piezoelectric devices 4_021 and the multiple tactile driving piezoelectric devices 4_022 can be arranged on the base substrate 401 in a checkerboard arrangement.

[0126] Alternatively, if Figure 8bAs shown, the plurality of tactile detection piezoelectric devices 4_021 can be divided into a plurality of columns, and the plurality of tactile driving piezoelectric devices 4_022 can also be divided into a plurality of columns, and a column of tactile detection piezoelectric devices 4_021 and a column of tactile driving piezoelectric devices 4_022 are arranged alternately.

For example, in a column of tactile detection piezoelectric devices 4_021, the bottom electrode 4021-1 of the tactile detection piezoelectric device 4_021 is electrically connected to the bottom electrode 4021-2 through the first connection portion 0221, and the bottom electrodes 4021-2 are electrically connected to each other through the first connection portion 0221. In addition, in a column of tactile driving piezoelectric devices 4_022, the bottom electrode 4021-3 of the tactile driving piezoelectric device 4_022 is electrically connected to the bottom electrode 4021-4 through the second connection portion 0211, and the bottom electrode 4021-4 is electrically connected to each other through the second connection portion 0211.

[0128] Alternatively, if Figure 8dAs shown, the multiple tactile detection piezoelectric devices 4_021 can be divided into multiple columns, and the multiple tactile driving piezoelectric devices 4_022 can also be divided into multiple columns, and a column of tactile detection piezoelectric devices 4_021 and a column of tactile driving piezoelectric devices 4_022 are arranged alternately. In addition, the tactile detection piezoelectric devices 4_021 and the tactile driving piezoelectric devices 4_022 are arranged in an array.

Each tactile driving piezoelectric device 4_022 is respectively connected to a tactile driving signal line 321 to transmit a signal through the tactile detection signal line 321 .

[0129] Alternatively, if Figure 8e As shown, the plurality of tactile detection piezoelectric devices 4_021 and the plurality of tactile driving piezoelectric devices 4_022 may also be arranged in the non-display area of ​​the display panel. Moreover, in one column, the tactile detection piezoelectric devices 4_021 and the tactile driving piezoelectric devices 4_022 are arranged alternately. Further, the tactile detection piezoelectric devices 4_021 and the tactile driving piezoelectric devices 4_022 may be connected to the eleventh pin of the first high-voltage amplifier circuit through the first circuit board.

[0130] Of course, the plurality of tactile detection piezoelectric devices and the plurality of tactile driving piezoelectric devices may also be arranged on the base substrate 401 in other arrangements, which is not limited in the present disclosure.

[0131] Exemplarily, in the tactile detection piezoelectric device, the bottom electrode 4021 is grounded, the binding electrode 4024 is connected to the driving detection end, and when a finger touches the surface of the base substrate 401, the top electrode 4022 generates a charge signal, which can be output through the driving detection end.

[0132] Exemplarily, in the tactile driving piezoelectric device, the bottom electrode 4021 is grounded, the binding electrode 4024 is connected to the driving voltage input terminal, the driving control signal input to the driving voltage input terminal is an AC voltage signal, and the AC voltage signal (V AC), so that an alternating electric field can be formed between the top electrode 4022 and the bottom electrode 4021, and the frequency of the alternating electric field is the same as the frequency of the AC voltage signal. Under the action of the alternating electric field, the piezoelectric layer 4023 is deformed and generates a vibration signal, and the frequency of the vibration signal is the same as the frequency of the alternating electric field. When the frequency of the vibration signal is close to or equal to the natural frequency of the substrate 401, the substrate 401 resonates, the amplitude is enhanced, and a tactile feedback signal is generated. When a finger touches the surface of the substrate 401, the change in friction can be clearly felt. In practical applications, the friction on the surface of the substrate 401 can be adjusted by the resonance generated between the piezoelectric layer 4023 and the substrate 401, so that the texture of the object can be reproduced on the surface of the substrate 401.

The piezoelectric layer 4023 of all drivers 402 can be a patterned structure or a whole surface structure. The top electrode 4022 of all drivers 402 can be a patterned structure, for example, the top electrode 4022 of all drivers 402 can be a patterned structure corresponding to the piezoelectric layer 4023 one by one.

[0135] In a specific implementation, the material of the piezoelectric layer can be lead zirconate titanate (Pb(Zr,Ti)O3, PZT), or aluminum nitride (AlN), ZnO (zinc oxide), barium titanate (BaTiO3), lead titanate (PbTiO3), potassium niobate (KNbO3), lithium niobate (LiNbO3), lithium tantalate (LiTaO3), lanthanum gallium silicate (La3Ga5SiO 14 ), and the material for making the piezoelectric layer can be specifically selected according to the actual use needs of those skilled in the art, and is not limited here. Among them, when PZT is used to make the piezoelectric layer, since PZT has a high piezoelectric coefficient, the piezoelectric characteristics of the corresponding display panel 400 are guaranteed, and the corresponding display panel 400 can be applied to the tactile feedback device, and PZT has a high light transmittance, and when it is integrated into the display device, it does not affect the display quality of the display device.

[0136] In the specific implementation process, the top electrode and the bottom electrode of the piezoelectric device are transparent conductive materials, for example, they can be made of indium tin oxide (ITO), indium zinc oxide (IZO), titanium-gold (Ti-Au) alloy, titanium-aluminum-titanium (Ti-Al-Ti) alloy, titanium-molybdenum (Ti-Mo) alloy, and can also be made of one of titanium (Ti), gold (Au), silver (Ag), molybdenum (Mo), copper (Cu), tungsten (W), and chromium (Cr).

Exemplarily, the support layer 404 may include a support portion 411 that is located around the base substrate 401 and is arranged around all drivers 402. Optionally, the shape of the orthographic projection of the support layer 404 (support portion 411) on the base substrate 401 includes a square, a triangle, a circle, a trapezoid or a polygon, etc. Of course, the present disclosure does not limit the specific position of the support layer 404.
