Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to driving circuits, methods, and display panels for display panels. Background Technology

[0002] Currently, high-resolution touch display panels (such as automotive displays and mobile phone displays) widely adopt TouchMUX (Multiplexer) structures to transmit multiple touch signals. However, the TouchMUX design in related technologies has the following problems: Since the touch detection frequency is generally higher than the display frequency, coupled with the MUX multiplexing design, the switching speed and conduction capability of the MUXTFT are required to be high. Under this design, the conduction impedance of the MUXTFT is too high, which will lead to signal transmission attenuation. Ultimately, after the touch ends, when normal display is performed, the power supply of VCOM (common electrode voltage) of different touchpads is uneven, resulting in voltage difference, which in turn leads to abnormal screen phenomena such as equally spaced blocks or horizontal lines.

[0048] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that the embodiments of this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the embodiments of this application with unnecessary detail.

[0049] Currently, high-resolution touch display panels (such as automotive displays and mobile phone displays) widely adopt TouchMUX (Multiplexer) structures to transmit multiple touch signals. However, the TouchMUX design in related technologies has the following problems: Since the touch detection frequency is generally higher than the display frequency, and given the MUX multiplexing design, the switching speed and conduction capability of the MUXTFT (Thin Film Transistor) are required to be high. In this design, the on-resistance of the MUXTFT is too high, leading to signal transmission attenuation. Ultimately, after the touch ends and during normal display, the VCOM (common electrode voltage) power supply of different touchpads is uneven, resulting in voltage differences and causing abnormal image phenomena such as evenly spaced blocks or horizontal lines. Furthermore, this TouchMUX design has only a single VCOM drive path, lacking sufficient VCOM input points in the Y direction of the display panel. This means that when switching touch modes, potential changes cause uneven VCOM distribution, further exacerbating the aforementioned abnormal image phenomena.

[0050] Based on this, embodiments of this application provide a driving circuit, method, and display panel for a display panel. By replacing the single-gate TFT in the traditional TouchMUX design with a dual-gate thin-film transistor or a combination of two thin-film transistors connected in parallel, the charge mobility is improved, resulting in lower on-resistance under the same gate driving voltage, thereby enhancing signal transmission capability. Simultaneously, it reduces the potential difference of the touch module, improving signal quality during touch sensing. It also reduces the problem of unstable power supply to the common electrode voltage in touch sensing mode, making touch sensing more accurate. Increased transistor switching capability and speed reduce the occurrence of periodic blocks, improving display uniformity.

[0051] The driving circuit, method, and display panel provided in this application embodiment are specifically described through the following embodiments. First, the driving circuit of the display panel in this application embodiment is described.

[0052] This application provides a driving circuit for a display panel, referring to... Figure 1 , Figure 1 This is a schematic diagram of a driving circuit for a display panel according to an embodiment of this application. In this embodiment, the driving circuit for the display panel includes:

[0053] The integrated driving module 10 is used to generate the initial touch signal and also to output the common electrode voltage.

[0054] The first gating module 20 has its first end electrically connected to the first end of the integrated driving module 10. The first gating module 20 is used to provide a touch signal transmission channel or transmit a common electrode voltage.

[0055] The touch module 30 has its first end electrically connected to the second end of the first gating module 20. The touch module 30 is used to generate a sensing measurement in response to a touch action and transmit the sensing measurement to the integrated driving module 10 via the first gating module 20 and superimpose it with the initial touch signal.

[0056] The second gating module 40 has its first end electrically connected to the second end of the integrated driving module 10 and its second end electrically connected to the second end of the touch module 30. The second gating module 40 is used to transmit the common electrode voltage to the touch module 30.

[0057] The transistors in the first gating module 20 and the second gating module 40 are either dual-gate thin-film transistors or composed of two thin-film transistors connected in parallel.

[0058] In this embodiment, the integrated driver module 10 can be implemented by software or hardware. The integrated driver module 10 has the functions of both SourceIC (source driver chip) and TouchIC (touch chip). It can generate the initial touch signal, output the VCOM common electrode voltage for display driving, and monitor the changes in the initial touch signal to know the sensing measurement superimposed on the initial touch signal by the touch module 30 based on the sensed touch action, and then execute the operation corresponding to the touch action. As an example, the integrated driver module 10 can be implemented using a TDDI (Touch and Display Driver Integration) chip.

[0059] In this embodiment, the first gating module 20 and the second gating module 40 are used to determine the signal path between the integrated driving module 10 and the touch module 30. The first gating module 20 can serve as a touch signal transmission channel between the integrated driving module 10 and the touch module 30 during the touch sensing stage. During the screen display stage, it can transmit the common electrode voltage output by the integrated driving module 10 to the touch module 30. The specific control method can be determined according to the actual situation. Both the first gating module 20 and the second gating module 40 contain multiple transistors for determining the on / off state of the signal path. It should be noted that, unlike the single-gate TFT used in the traditional design, this embodiment uses a dual-gate TFT or two TFTs connected in parallel with independent gates (e.g., the source and drain of the two TFTs are connected in common) to replace the traditional single-gate TFT design, so that the on-resistance is lower under the same gate driving voltage, thereby enhancing the signal transmission capability.

[0060] As an example, a TFT can be viewed as a variable resistor controlled by the gate voltage. Using a dual-gate TFT or two TFTs in parallel is equivalent to providing two parallel paths for the current. According to the formula for parallel resistance: 1 / R 总 = 1 / R1 + 1 / R2 (where R 总 The total resistance after parallel connection (R1 and R2 are the resistances of the two TFTs respectively) is equal to the sum of the reciprocals of the individual resistances. Therefore, the total impedance after parallel connection will be less than the impedance of a single TFT. In addition, the two gates can control the threshold voltage, channel width, and carrier concentration respectively, which can effectively reduce the channel resistance and thus improve the carrier mobility.

[0061] Reference Figure 2 In some feasible embodiments, the touch module 30 may specifically include:

[0062] The first touch unit 31 has its first end electrically connected to the second end of the second gating module 40, and its second end electrically connected to the second end of the first gating module 20.

[0063] The second touch unit 32 has its first end electrically connected to the second end of the second gating module 40, and its second end electrically connected to the second end of the first gating module 20.

[0064] In this embodiment, the touch module 30 consists of two parts: a first touch unit 31 and a second touch unit 32. The first touch unit 31 and the second touch unit 32 have the same function, but they also have the ability to perform different functions at the same time. For example, the following situations may occur: ① the first touch unit 31 performs touch sensing, and the second touch unit 32 receives the VCOM voltage provided by the integrated driver module 10; or ② the first touch unit 31 receives the VCOM voltage provided by the integrated driver module 10, and the second touch unit 32 performs touch sensing; or ③ both receive the VCOM voltage provided by the integrated driver module 10, etc. This embodiment does not limit this.

[0065] As an example, both the first touch unit 31 and the second touch unit 32 may include multiple TPPADs (touchpads) for sensing the user's touch actions and superimposing the corresponding sensing measurements onto the initial touch signal. The process of superimposing the sensing measurements onto the initial touch signal can also be regarded as the process of modulating the initial touch signal.

[0066] Reference Figure 3 In some feasible embodiments, the first gating module 20 may specifically include:

[0067] The first transistor T1 has its first terminal electrically connected to the first terminal of the integrated driving module 10, and its second terminal electrically connected to the second terminal of the first touch unit 31.

[0068] The second transistor T2 has its first terminal electrically connected to the first terminal of the integrated driving module 10, and its second terminal electrically connected to the second terminal of the second touch unit 32.

[0069] The second gating module 40 may specifically include:

[0070] The third transistor T3 has its first terminal electrically connected to the second terminal of the integrated driving module 10, and its second terminal electrically connected to the first terminal of the second touch unit 32.

[0071] The fourth transistor T4 has its first terminal electrically connected to the second terminal of the integrated driving module 10, and its second terminal electrically connected to the first terminal of the first touch unit 31.

[0072] In this embodiment, a structural schematic diagram of a specific implementation example of the first gating module 20 and the second gating module 40 is provided, which consists of... Figure 3 It is known that the first transistor T1 to the fourth transistor T4 are all dual-gate TFTs. This structure is symmetrical from left to right, which can improve the driving capability of the TFT, increase the VCOM thrust to the first touch unit 31 and the second touch unit 32, reduce the unstable VCOM power supply in the touch sensing mode, make the touch sensing more accurate, and thus improve the abnormal screen situation.

[0073] As an example, when the first transistor T1 and the third transistor T3 are turned on, the second transistor T2 and the fourth transistor T4 are turned off. At this time, the first touch unit 31 performs touch sensing, and the second touch unit 32 receives the VCOM voltage provided by the integrated driving module 10 via the third transistor T3. Conversely, when the second transistor T2 and the fourth transistor T4 are turned on, the first transistor T1 and the third transistor T3 are turned off. At this time, the second touch unit 32 performs touch sensing, and the first touch unit 31 receives the VCOM voltage provided by the integrated driving module 10 via the fourth transistor T4.

[0074] Reference Figure 4 In some feasible embodiments, the driving circuit of the display panel may further include:

[0075] The fifth transistor T5 has its first terminal electrically connected to the third terminal of the integrated driving module 10, and its second terminal electrically connected to the second terminal of the first touch unit 31 and the first terminal of the second touch unit 32.

[0076] The sixth transistor T6 has its first terminal electrically connected to the third terminal of the integrated driving module 10, and its second terminal electrically connected to the second terminal of the first touch unit 31 and the first terminal of the second touch unit 32.

[0077] In this embodiment, by introducing a fifth transistor T5 and a sixth transistor T6, a VCOM input point can be added in the middle of the touch module 30 in the Y direction of the display panel (or between any two TP PADs). If the VCOM voltage provided via the second gating module 40 in the previous embodiment is considered to be output from the second terminal SX_DUM1 of the integrated driver module 10, then the VCOM voltage provided from this newly added input point can be considered to be output from the third terminal SX_DUM2 of the integrated driver module 10. SX_DUM2 and SX_DUM1 are independent of each other. The increased number of VCOM input points enhances the display driving capability, allowing the VCOM signal to be evenly transmitted to the first touch unit 31 and the second touch unit 32. This avoids uneven VCOM power supply during touch sensing, improves display stability, and prevents abnormal image phenomena such as image blocks or horizontal lines.

[0078] As an example, by adjusting the in-plane design, the fifth transistor T5 and the sixth transistor T6 can be turned on when the touch sensing is completed and the display stage is entered. This adds a VCOM input point between the first touch unit 31 and the second touch unit 32, so that the VCOM signal can be evenly transmitted to the first touch unit 31 and the second touch unit 32.

[0079] Reference Figure 5 In some feasible embodiments, the driving circuit of the display panel may further include:

[0080] The seventh transistor T7 has its first terminal electrically connected to the third terminal of the integrated drive module 10, and its second terminal electrically connected to the second terminal of the first touch unit 31.

[0081] The eighth transistor T8 has its first terminal electrically connected to the third terminal of the integrated drive module 10, and its second terminal electrically connected to the first terminal of the second touch unit 32.

[0082] In this embodiment, taking the display panel as an example, which includes multiple driving circuits composed of a first gating module 20, a touch module 30, and a second gating module 40, by setting the seventh transistor T7 to be electrically connected to the first touch unit 31 in each driving circuit and the eighth transistor T8 to be electrically connected to the second touch unit 32 in each driving circuit, the technical effect of increasing the VCOM input point can be achieved, so that the VCOM signal can be uniformly transmitted to the first touch unit 31 and the second touch unit 32.

[0083] As an example, by adjusting the in-plane design, when the first touch unit 31 performs touch sensing, the first transistor T1 is turned on, the fourth transistor T4 and the seventh transistor T7 are turned off, the second transistor T2 is turned off, and the third transistor T3 and the eighth transistor T8 are turned on. At this time, the second touch unit has two VCOM input points. After the third transistor T3 and the eighth transistor T8 are turned on, the left half of the display panel is provided by the left SX_DUM1 and the right SX_DUM2, and the right half of the display panel is provided by the right SX_DUM1 and the right SX_DUM2. Similarly, when the second touch unit 32 performs touch sensing, the first touch unit 31 has two VCOM input points. After the fourth transistor T4 and the seventh transistor T7 are turned on, the left half of the screen is provided by SX_DUM1 and SX_DUM2 on the left, and the right half of the screen is provided by SX_DUM1 on the right and SX_DUM2 on the left. When the touch sensing is completed and the display stage is entered, the seventh transistor T7 and the eighth transistor T8 are both turned on. Based on the two VCOM input points, the VCOM signal can be evenly transmitted to the first touch unit 31 and the second touch unit 32.

[0084] In some feasible embodiments, the driving circuit of the display panel may further include:

[0085] A multiplexer is used to select and control the transistors in the drive circuit of the display panel.

[0086] In this embodiment, each transistor in the driving circuit of the display panel can be controlled by a multiplexer, that is, the controlled terminal of the transistor in each embodiment is electrically connected to the multiplexer.

[0087] This application provides a driving circuit for a display panel. By replacing the single-gate TFT in the traditional TouchMUX design with a dual-gate thin-film transistor or a transistor composed of two thin-film transistors connected in parallel, the charge mobility is improved, resulting in lower on-resistance under the same gate driving voltage, thereby enhancing signal transmission capability. It also reduces the potential difference of the touch module, improving signal quality during touch sensing. Furthermore, it reduces the problem of unstable power supply to the common electrode voltage in touch sensing mode, making touch sensing more accurate. Increased transistor switching capability and speed reduce the occurrence of periodic blocks, improving display uniformity. In addition, by adding a VCOM input point, the VCOM signal can be uniformly transmitted to the touch module, further improving display stability and preventing abnormal screen phenomena.

[0088] Furthermore, this application embodiment also provides a driving method for a display panel, which is applied to the aforementioned driving circuit of the display panel, referring to... Figure 6In this embodiment, the driving method of the display panel includes steps S10 to S30.

[0089] Step S10: Generate initial touch signal through integrated driver module;

[0090] Step S20: The touch module responds to the touch action from the outside and superimposes the sensor measurement onto the initial touch signal;

[0091] Step S30: Monitor changes in the initial touch signal through the integrated driver module to execute operations corresponding to the touch action.

[0092] Reference Figure 7 In some feasible embodiments, the driving method for the display panel further includes:

[0093] Step S40: Output the common electrode voltage to the first gating module or the second gating module through the integrated drive module;

[0094] Step S50: The common electrode voltage is transmitted to the touch module through the first gating module or the second gating module.
