Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the embodiments of the present application, the words "first," "second," "third," "fourth," "fifth," "sixth," etc. are used to distinguish between identical items or similar items that have substantially the same function and function, and are merely used for clarity in describing the technical solutions of the embodiments of the present application, and are not to be construed as indicating or implying relative importance or implying that the number of technical features indicated is indicated.
In embodiments of the application, the meaning of "at least one" is one or more, unless specifically defined otherwise.
In embodiments of the present application, the term "electrically connected" may refer to two components being directly electrically connected, or may refer to two components being electrically connected via one or more other components; "electrically connected" may mean electrically connected by wires, or by radio signals.
With the development of technology, display devices have more and more functions, such as: and a touch control function. The user can perceive the vibration of the screen when pressing the display device, and the user perceives the vibration of the screen by means of the neuron. Studies have shown that if combined with appropriate acceleration, the neurons of the user's finger can detect very small movements, such as: when the acceleration is greater than or equal to 1.5g, only 0.1mm of movement can be perceived by a user; but when the acceleration is less than 1.5g, it is insufficient to produce an optimal haptic effect. It is therefore desirable to design a device that is capable of producing the proper acceleration and has a strong stimulating displacement and to control the device to produce more efficient vibrations.
The current mainstream solutions include eccentric rotating block motor and linear resonant actuator vibration technology, piezoelectric ceramic fixed at the periphery of the screen vibration technology, accurate local vibration technology of integrating piezoelectric ceramic units on a glass substrate, and the like. However, in either case, two independent systems of the display system and the Vibration system are simply combined together, and as shown in fig. 1, the display panel 2 is controlled by the Tcon (Timing Controller) through the source driver by the timing controller 4, and the vibrator (Vibration Block) 3 is driven by the Vibration driver (Vibration Drive) 5 to vibrate, that is, the display and Vibration are isolated. It follows that the display system and the vibration system in the related art have no relation to each other, do not share any unit devices, and may interfere with each other's operation.
Based on the above, the embodiment of the present application provides a driving circuit, referring to fig. 2, including: at least one source driver applied to a display device including a display panel 2 and a vibrator 3; the source driver is electrically connected to the display panel 2 and the vibrator 3, respectively, and is configured to time-divisionally drive the display panel 2 and the vibrator 3.
The structure, type, number, etc. of the source drivers are not particularly limited. For example, the source driving module may include SIC (Source Integratedcircuit, source integrated chip). Fig. 2 illustrates the number of the source drivers as four, namely, the first source driver 11, the second source driver 12, the third source driver 13, and the fourth source driver 14.
The display panel may be an LCD (Liquid Crystal Display ) display panel, and the specific type of the display panel is not limited herein.
The vibrator may be a device that generates vibration under a suitable acceleration and a strong stimulus displacement, and the specific type of the vibrator is not limited herein.
The display device described above includes a display panel and a vibrator, and the positions of the display panel and the vibrator are not particularly limited.

The above-described source driver configured to time-divisionally drive the display panel and the vibrator means: the process of driving the display panel by the source driver and the process of driving the vibrator by the source driver do not exist at the same time, and are separately performed.
In the driving circuit provided by the embodiment of the application, the source driver is electrically connected with the display panel and the vibrator respectively and is configured to drive the display panel and the vibrator in a time-sharing manner, so that the driving of the display panel and the driving of the vibrator can be realized by the source driver, namely, the display driving and the vibration driving are integrated, and the switching function can be realized in the source driver through multiple paths due to the time-sharing driving of the display panel and the vibrator, so that the interference of the display panel and the vibrator on the work of each other is avoided, and the user experience is good.
Alternatively, referring to fig. 2, the driving circuit includes a plurality of source drivers, each of which is electrically connected to the display panel 2 and the vibrator 3, and adjacent source drivers, respectively. Therefore, the display panel and the vibrator can be controlled by a plurality of source drivers in a regional mode, and more accurate regional control is realized.

Meanwhile, the timing controller 4 may also transmit a control signal (LR) of a data transmission direction and sequence, a synchronization signal (TP) of start and end of each line, and the like to the first, second, third, and fourth source drivers 11, 12, 13, and 14. Wherein adjacent source drivers are electrically connected such that, as shown in fig. 2, the first source driver 11 can supply a control signal (LR 1) for transmitting a data transmission direction and order to the second source driver 12, the second source driver 12 can supply a control signal (LR 2) for transmitting a data transmission direction and order to the third source driver 13, and the third source driver 13 can supply a control signal (LR 4) for transmitting a data transmission direction and order to the fourth source driver 14.
Alternatively, referring to fig. 3, the source driver includes an input module 60, a buffer module 61, and an output module 62.
Referring to fig. 3, a first input terminal of the buffer module 61 is electrically connected to the input module 60, a second input terminal of the buffer module 61 is electrically connected to an output terminal of the buffer module 61, and an output terminal of the buffer module 61 is electrically connected to the output module 62; the buffer module 61 is configured to provide any one of a display driving signal and a vibration driving signal to the output module 62 in a time-sharing manner according to the control signal; the input module 60 is configured to time-divisionally supply any one of a display driving signal and a vibration driving signal to the buffer module 61; the output module 62 is configured to output any one of the display drive signal and the vibration drive signal in a time-sharing manner.

The type of the vibration drive signal is not particularly limited here. By way of example, the vibration drive signals may include positive polarity vibration drive signals, negative polarity vibration drive signals, and the like.
The specific circuit structures of the input module, the buffer module and the output module are not limited, and only need to satisfy the corresponding functions.
In the driving circuit provided by the embodiment of the application, the buffer module is configured to provide any one of the display driving signal and the vibration driving signal to the output module according to the control signal in a time sharing manner, namely, the buffer module is shared in the source driver to realize the control of display and vibration in a time sharing manner. The buffer module is used for driving the external pixels and is the module with the most occupied area inside the source driver, so the buffer module is shared, the area of the source driver can be effectively reduced on the basis of integrating display driving and vibration driving of the source driver, and the cost is saved.
Alternatively, referring to fig. 4, the buffer module 61 includes a first buffer unit 611 and a second buffer unit 612.

The first buffer unit 611 and the second buffer unit 612 are collectively configured to time-divisionally supply any one of a display driving signal and a vibration driving signal to the output module 62 according to a control signal. Therefore, the first buffer unit and the second buffer unit can be shared, so that the area of the source electrode driver is effectively reduced on the basis of integrating display driving and vibration driving, and the cost is saved.

By executing step S1, the driving of the display panel and the driving of the vibrator can be realized by the source driver, that is, the display driving and the vibration driving are integrated, and the switching function can be realized by selecting a plurality of channels inside the source driver due to the time-sharing driving of the display panel and the vibrator, so that the interference of the display panel and the vibrator to each other is avoided, and the user experience is good.
In addition, since the number of display pixels in the display panel is much larger than the number of shaking units in the shaking unit, the driving current of the shaking unit can be much larger than that of the display pixels, so that tens to hundreds of pixel driving channels can be connected in parallel to drive the shaking unit.
Referring to fig. 11 to 14, the driving method of the driving circuit is specifically described by taking N-type transistors as the first switching tube T1, the second switching tube T2, the third switching tube T3, the fourth switching tube T4, the fifth switching tube T5 and the sixth switching tube T6.
Referring to fig. 11, in the first state, at a first moment, the first buffer unit 611 is electrically connected to the first reference voltage terminal 6011 under the control of the control signal data_n+1, and the second buffer unit 612 is electrically connected to the second reference voltage terminal 6012 under the control of the control signal data_n. At this time, the first reference voltage terminal 6011 inputs the first display control signal of positive polarity to the first input terminal of the first buffer unit 611, and the second reference voltage terminal 6012 inputs the second display control signal of negative polarity to the first input terminal of the second buffer unit 612. Since the first polarity inversion signal line POL1 inputs a low level, the first switching tube T1 and the second switching tube T2 are turned off (the switching tubes are turned off by broken lines in the drawing); the second polarity inversion signal line POL2 inputs a high level so that the third and fourth switching transistors T3 and T4 are turned on. Accordingly, the first display control signal output from the output terminal of the first buffer unit 611 is output to the second output signal line out_n+1 through the third switching transistor T3, and the second display control signal output from the output terminal of the second buffer unit 612 is output to the first output signal line out_n through the fourth switching transistor T4.

Since the first polarity inversion signal line POL1 inputs a high level, the first and second switching transistors T1 and T2 are turned on; the second polarity inversion signal line POL2 inputs a low level so that the third switching transistor T3 and the fourth switching transistor T4 are turned off (the switching transistors are turned off by dotted lines in the drawing). Accordingly, the first display control signal output from the output terminal of the first buffer unit 611 is output to the first output signal line out_n through the first switching transistor T1, and the second display control signal output from the output terminal of the second buffer unit 612 is output to the second output signal line out_n+1 through the second switching transistor T2.

The Vibration voltage signal line Vibration provides a first Vibration driving signal with positive polarity, at this time, the first diode 6021 is turned off, the second diode 6022 is turned on, the first Vibration driving signal is transmitted to the first input end of the first buffer unit 611 via the first resistor, the first input end of the second buffer unit 612 can only receive a voltage with a small value to keep the second buffer unit 612 normal, and the output end of the second buffer unit 612 does not output a voltage. Then, the output terminal of the first buffer unit 611 outputs the first vibration driving signal. Since the time-sharing control signal provided by the time-sharing control signal line VS is at a high level, the fifth switching tube T5 is turned on, the sixth switching tube T6 is turned off (the switching tube is turned off by the dotted line in the drawing), and the first polarity inversion signal line POL1 and the second polarity inversion signal line POL2 are both input at a low level, and the first switching tube T1, the second switching tube T2, the third switching tube T3, and the fourth switching tube T4 are all turned off, so that the fifth switching tube T5 outputs the first vibration driving signal to the second output signal line out_v.
Referring to fig. 14, in the second state, at a second moment, the first buffer unit 611 is electrically connected to the second terminal of the first resistor R1 under the control of the control signal data_n+1, and the second buffer unit 612 is electrically connected to the second terminal of the second resistor R2 under the control of the control signal data_n. The Vibration voltage signal line Vibration provides a second Vibration driving signal with negative polarity, at this time, the first diode 6021 is turned on, the second diode 6022 is turned off, the second Vibration driving signal is transmitted to the first input end of the second buffer unit 612 via the first resistor, the first input end of the first buffer unit 611 can only receive a voltage with a small value to keep the first buffer unit 611 normal, and the output end of the first buffer unit 611 does not output a voltage. Then, the output terminal of the second buffer unit 612 outputs a second vibration driving signal. Since the time-sharing control signal provided by the time-sharing control signal line VS is at a low level, the fifth switching tube T5 is turned off (the switching tube is turned off by the dotted line in the figure), the sixth switching tube T6 is turned on, and the first polarity inversion signal line POL1 and the second polarity inversion signal line POL2 are all inputted with the low level, and the first switching tube T1, the second switching tube T2, the third switching tube T3, and the fourth switching tube T4 are all turned off, and the sixth switching tube T6 outputs the second vibration driving signal to the second output signal line out_v.
It should be noted that, an LCD is a display device using liquid crystal as a material, and the driving voltage of liquid crystal molecules cannot be fixed at a certain value, otherwise, polarization phenomenon occurs in the liquid crystal molecules for a long time, so that optical rotation characteristics are gradually lost. In order to avoid the deterioration of the characteristics of the liquid crystal molecules, the polarity of the driving voltage of the liquid crystal molecules must be changed, which requires dividing the display voltage in the LCD into two polarities, one positive and the other negative, that is, the purpose of setting the first display driving signal and the second display driving signal.
