[0042] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0043] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0044] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second", etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0045] like Figures 1 to 4 As shown, the present disclosure provides a driving circuit 1. The driving circuit 1 may include: a controller 2, a first signal input interface 3 and a protection module 4. Among them, the controller 2 can be used to perform logical operations, send control instructions, etc. The first signal input interface 3 can be used to access the voltage signal entering the driving circuit 1. The protection module 4 may have a protection input terminal 41 and a protection output terminal 42, the protection input terminal 41 can be electrically connected to the first signal input interface 3, the protection output terminal 42 can be electrically connected to the controller 2, and the protection module 4 can be configured so that when the voltage entering the protection module 4 is greater than a threshold value, the voltage output by the protection module 4 is less than or equal to the preset working voltage of the controller 2.

[0046] With such a configuration, when the voltage input from the first signal input interface 3 is too large, the high voltage can be shielded or reduced by the protection module 4. This can avoid the problem that the controller 2 is damaged due to the voltage input from the first signal input interface 3 being too large, thereby reducing the probability of damage to the drive circuit 1 and improving the working stability of the drive circuit 1.

[0047] It should be noted that, when the voltage entering the protection module 4 is less than or equal to the threshold, the voltage output by the protection module 4 may be the same as the voltage entering the protection module 4 .

[0048] In one embodiment, the above threshold value may be the same as the preset operating voltage of the controller 2, and the preset operating voltage of the controller 2 may be the rated voltage of the control, but is not limited thereto. The threshold value and the preset operating voltage of the controller 2 may be selected according to actual needs, and the present disclosure does not impose any specific restrictions on this.

[0049] In one embodiment, the controller 2 may be a control chip, for example, the controller 2 may be a single chip microcomputer or a central processing unit, etc. The type of the controller 2 may be a timing control chip, a power management chip or an LED (light-emitting diode) driver chip, but is not limited thereto.

[0050] like Figure 1 and Figure 4 As shown, there may be multiple controllers 2, and the multiple controllers 2 may be electrically connected to the first signal input interface 3, so that the drive circuit 1 can perform multiple different logic operations or issue multiple different control instructions through the multiple controllers 2 to increase the function of the drive circuit 1. For example: the multiple control chips may include but are not limited to a timing control chip, a power management chip, and an LED driver chip.

[0051] In one embodiment of the present disclosure, the protection module 4 may include: a first resistance element 43 , a first switch element 44 and a second switch element 45 .

[0052] The first resistor element 43 may have a first end 431 and a second end 432 . The first end 431 of the first resistor element 43 may be electrically connected to the first signal input interface 3 , and the second end 432 of the first resistor element 43 may be grounded.

[0053] The first switch element 44 may have a first input terminal 441 , a first control terminal 442 , and a first output terminal 443 . The first input terminal 441 may be electrically connected to the first signal input interface 3 , and the first output terminal 443 may be electrically connected to the controller 2 .

[0054] The second switch element 45 may have a second input terminal 451, a second control terminal 452 and a second output terminal 453, the second input terminal 451 may be electrically connected to the first signal input interface 3, and the second input terminal 451 may be electrically connected to the first input terminal 441, the second control terminal 452 may be electrically connected to the second terminal 432, and the second output terminal 453 may be electrically connected to the first control terminal 442.

[0055] In this embodiment, when the voltage entering the protection module 4 is less than or equal to the threshold, the first switch element 44 can be opened and the second switch element 45 can be closed, so that the voltage entering the protection module 4 can be directly output to the controller 2 from the first switch element 44.

[0056] When the voltage entering the protection module 4 is greater than the threshold, the first switch element 44 can be closed and the second switch element 45 can be opened. At this time, the voltage entering the protection module 4 will not be directly output to the controller 2 through the first switch element 44, but will be released through the first switch element 44 and the first resistor element 43. Therefore, in this embodiment, the voltage output by the protection module 4 can be 0 or close to 0, so that the voltage output by the protection module 4 can be less than the preset working voltage of the controller 2, thereby effectively protecting the controller 2 from being burned by a higher voltage, further reducing the probability of damage to the drive circuit 1, and further improving the working stability of the drive circuit 1.

[0057] In one embodiment, Figure 1 and Figure 4As shown, the first switch element 44 may be a PMOS transistor, and the second switch element 45 may be a transistor, such as a PNP transistor. When the voltage entering the protection module 4 is less than or equal to the threshold, Vgs=-Vsda, where Vgs is the voltage of the first control terminal 442, and Vsda is the voltage of the first input terminal 441. At this time, the first switch element 44 is turned on, and the voltage of the first output terminal 443 is the same as the voltage of the first input terminal 441, so that the voltage entering the protection module 4 can be directly output to the controller 2. When the voltage entering the protection module 4 is greater than the threshold, Vgs=0, at this time, the first switch element 44 is turned off, and the output voltage of the first output terminal 443 is 0 or close to 0.

[0058] However, the first switch element 44 and the second switch element 45 may also be other types of switch elements and may be configured according to actual needs, which are all within the protection scope of the present disclosure.

[0059] In one embodiment, the protection module 4 may further include: a voltage stabilizing element 46. The voltage stabilizing element 46 may have a voltage stabilizing input terminal 461 and a voltage stabilizing output terminal 462. The second terminal 432 of the first resistor element 43 and the second control terminal 452 of the second switch element 45 may be electrically connected to the voltage stabilizing input terminal 461, and the voltage stabilizing output terminal 462 may be grounded. With such a configuration, a higher voltage may be released through the voltage stabilizing element 46, thereby further preventing a higher voltage from being input to the controller 2 and causing damage to the controller 2.

[0060] In one embodiment, the protection module 4 may further include: a second resistor element 47. The second resistor element 47 may have a third end 471 and a fourth end 472. The third end 471 of the second resistor element 47 may be electrically connected to the second end 432 of the first resistor element 43, and the third end 471 of the second resistor element 47 may be electrically connected to the voltage stabilization input end 461, and the fourth end 472 of the second resistor element 47 may be electrically connected to the second control end 452.

[0061] The protection module 4 may further include: a third resistance element 48. The third resistance element 48 may have a fifth end 481 and a sixth end 482. The fifth end 481 of the third resistance element 48 may be electrically connected to the first control end 442, and the fifth end 481 of the third resistance element 48 may be electrically connected to the second output end 453, and the sixth end 482 of the third resistance element 48 is grounded.

[0062] In one embodiment, the resistance value of the first resistor element 43 may be greater than the resistance value of the second resistor element 47, and the resistance value of the second resistor element 47 may be greater than the resistance value of the third resistor element 48, so as to better release the voltage, but it is not limited thereto.

[0063] In one embodiment of the present disclosure, the first signal input interface 3 may be a logic input power interface, for example, the first signal input interface 3 may be an SDA (serial data, data signal line of I2C bus) signal input interface or an input interface of panel input power, etc. However, it is not limited thereto, the first signal input interface 3 may also be other signal input interfaces, which may be set according to actual conditions, and all of which are within the protection scope of the present disclosure.

[0064] In one embodiment of the present disclosure, the driving circuit 1 may further include: a fourth signal input interface 8. The fourth signal input interface 8 may be a backlight power input interface, but is not limited thereto. The voltage value input by the fourth signal input interface 8 may be greater than the voltage value input by the first signal input interface 3, but is not limited thereto.

[0065] The above-mentioned driving circuit 1 is further described below with reference to a specific embodiment:

[0066] In one embodiment, Figures 1 to 4 As shown, the first signal input interface 3 can be an SDA signal input interface, the voltage threshold can be 3.3V, the resistance value of the first resistor element 43 can be 47KΩ, the resistance value of the second resistor element 47 can be 4.7KΩ, the resistance value of the third resistor element 48 can be 200Ω, the first switch element 44 can be a PMOS tube, the second switch element 45 can be a PNP type transistor, the voltage stabilizing element 46 can be a voltage stabilizing diode, and the controller 2 can have three, and the three controllers 2 can be a timing control chip, a power management chip and an LED driver chip respectively.

[0067] When the input voltage of the SDA signal input interface is less than or equal to 3.3V, the first switch element 44 works and the second switch element 45 does not work, and the protection module 4 outputs the voltage normally. When the input voltage of the SDA signal input interface is greater than 3.3V, the first switch element 44 does not work and the second switch element 45 works, and the output of the protection module 4 is 0V or close to 0V.

[0068] like Figure 2 and Figure 3 As shown in the figure, through simulation verification, when the input voltage of the SDA signal input interface is 3.3V (such as Figure 2 When the output voltage of the protection module 4 is 3.297V (shown as the solid line in Figure 2 The dashed line in the figure is consistent with the theoretical value. When the input voltage of the SDA signal input interface is 3.4V (as shown in Figure 3 When the output voltage of protection module 4 is 19mV (as shown by the solid line in Figure 3 ), which is consistent with the theoretical value. Thus, the protection function of the driving circuit 1 can be verified.

[0069] It should be noted that the above description of the driving circuit 1 is only by way of example, and the above-mentioned first signal input interface 3, voltage threshold, resistance value of the first resistor element 43, resistance value of the second resistor element 47, resistance value of the third resistor element 48, first switch element 44, second switch element 45, voltage stabilizing element 46, and controller 2 can all be selected and set according to actual conditions, which are all within the protection scope of the present disclosure.

[0070] Another aspect of the present disclosure provides a driving module. Figures 1 to 4 As shown, the driving module may include: a connector 5, a second signal input interface 6, a third signal input interface 7 and a driving circuit 1. The driving circuit 1 may be the driving circuit 1 described above, and the driving circuit 1 may include a fourth signal input interface 8. The second signal input interface 6 and the third signal input interface 7 can be electrically connected to the first signal input interface 3 and the fourth signal input interface 8 through the connector 5.

[0071] It should be noted that, in the case of normal access, the second signal input interface 6 is electrically connected to the first signal input interface 3 through the connector 5, and the third signal input interface 7 is electrically connected to the fourth signal input interface 8 through the connector 5. At this time, both the first signal input interface 3 and the fourth signal input interface 8 can be connected to normal voltage, and the controller 2 can work normally. When an oblique insertion or misalignment occurs, the third signal input interface 7 will be electrically connected to the first signal input interface 3. At this time, since the input voltage of the third signal input interface 7 may be higher than the preset working voltage of the controller 2, the voltage connected to the first signal input interface 3 is higher than the preset working voltage of the controller 2, causing the controller 2 to burn out.

[0072] Furthermore, it should be noted that in the specific description of the driving module, the present disclosure does not repeat the specific structure and technical effects of the driving circuit 1. The specific structural and technical effects of the driving circuit 1 can refer to the above-mentioned specific description of the driving circuit 1, which is also within the protection scope of the present disclosure.

[0073] Since the driving module provided by the present disclosure includes the driving circuit 1 described above. The driving circuit 1 described above includes: a controller 2, a first signal input interface 3 and a protection module 4. Among them, the controller 2 can be used to perform logical operations, send control instructions, etc. The first signal input interface 3 can be used to access the voltage signal entering the driving circuit 1. The protection module 4 can have a protection input terminal 41 and a protection output terminal 42, the protection input terminal 41 can be electrically connected to the first signal input interface 3, and the protection output terminal 42 can be electrically connected to the controller 2. The protection module 4 can be configured so that when the voltage entering the protection module 4 is greater than a threshold value, the voltage output by the protection module 4 is less than or equal to the preset working voltage of the controller 2.

[0074] With such arrangement, if miswiring or slanted insertion occurs, resulting in the third signal input interface 7 being electrically connected to the first signal input interface 3, and the voltage connected to the first signal input interface 3 is too large, the protection module 4 can be used to shield or reduce the high voltage, thereby avoiding the problem of excessive voltage input from the first signal input interface 3, which may cause damage to the controller 2. This can reduce the probability of damage to the drive module and improve the working stability of the drive module.

[0075] In one embodiment of the present disclosure, the type of the second signal input interface 6 is the same as the type of the first signal input interface 3 , that is, it can be understood that when the first signal input interface 3 is an SDA signal input interface, the second signal input interface 6 is also an SDA signal input interface.

[0076] The type of the third signal input interface 7 is the same as the type of the fourth signal input interface 8 , that is, it can be understood that when the fourth signal input interface 8 is a backlight power input interface, the second signal input interface 6 is also a backlight power input interface.

[0077] In one embodiment, the driving module can be located at the system end and the panel end respectively, wherein the connector 5, the second signal input interface 6 and the third signal input interface 7 can be located at the system end; the first signal input interface 3, the fourth signal input interface 8 and the controller 2 can be located at the panel end, but not limited to this.

[0078] In another aspect, the present disclosure provides a display device. Figures 1 to 4 As shown, the display device may include the driving circuit 1 described above, or the display device may include the driving module described above.

[0079] It should be noted that in the specific description of the driving module, the present disclosure does not repeat the specific structure and technical effects of the driving circuit 1. The specific structural and technical effects of the driving circuit 1 can refer to the above specific description of the driving circuit 1, which is also within the protection scope of the present disclosure.

[0080] It should be noted that, in the specific description of the display device, the present disclosure does not repeat the specific structure and technical effects of the driving circuit 1 and the driving module. The specific structural and technical effects of the driving circuit 1 and the driving module can refer to the above-mentioned specific description of the driving circuit 1 and the driving module, which is also within the protection scope of the present disclosure.

[0081] Since the display module provided by the present disclosure includes the driving circuit 1 or driving module described above. The driving module also includes the driving circuit 1 described above. The driving circuit 1 described above includes: a controller 2, a first signal input interface 3 and a protection module 4. Among them, the controller 2 can be used to perform logical operations, send control instructions, etc. The first signal input interface 3 can be used to access the voltage signal entering the driving circuit 1. The protection module 4 can have a protection input terminal 41 and a protection output terminal 42, the protection input terminal 41 can be electrically connected to the first signal input interface 3, and the protection output terminal 42 can be electrically connected to the controller 2.

This can avoid the problem that the controller 2 is damaged due to the voltage input from the first signal input interface 3 being too high, thereby reducing the probability of damage to the display module and improving the working stability of the display module.
