[0031] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the oscillation frequency control method, system and display device provided by the present disclosure will be described in detail below in conjunction with the accompanying drawings.

[0033] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in combination with the embodiment may be included in at least one embodiment of the present application.

Those skilled in the art will understand, both explicitly and implicitly, that the embodiments described herein can be combined with other embodiments where no inconsistency exists.

[0034] Unless otherwise defined, technical or scientific terms used herein shall have their ordinary meaning as understood by those of ordinary skill in the art to which this application pertains. As used herein, the terms "a," "one," "one," "the," and similar terms do not denote a limitation of quantity and may denote singular or plural.

The symbol " / " generally indicates that the related objects before and after it are in an "or" relationship.

[0035] A display device with communication capabilities generally includes a communication module for enabling communication between the display device and the outside world, and a display driver module (also called a "display driver chip" or Display Driver IC, abbreviated as DDIC) for providing a drive signal to the display to drive the display, and the display driver module includes at least one oscillator for generating the system clock required by the display driver module.

[0036] FIG. 1 is a conceptual diagram illustrating interference between an oscillator in a display driver module and a communication module in an embodiment of the present disclosure. FIG. 2A is a conceptual diagram illustrating harmonics generated by the oscillator falling within the communication operating frequency band of the communication module. FIG. 2B is a conceptual diagram illustrating harmonics generated by the oscillator falling outside the communication operating frequency band of the communication module. As shown in FIGS. 1 to 2B, in actual applications, some display devices have a problem in which the communication quality of the communication module 2 deteriorates after the entire machine is assembled. Research has shown that one of the main reasons for the deterioration of the communication quality of the communication module 2 in some display devices is that the oscillation operating frequency of the oscillator in the display driver module 1 is set and remains fixed during the machine assembly stage. During use of the display device, the oscillator operates at the set oscillation operating frequency, generating several harmonics. When these harmonics enter the communication operating frequency band in which the communication module 2 currently operates, they cause resonance and interference, adversely affecting the signal transmission and signal reception capabilities of the communication module 2.

[0037] Because the oscillator is fixed in the related art, in order to ensure the communication quality of the communication module 2, the related art often selects the communication operating frequency band of the communication module 2 to avoid the frequencies of harmonics generated by the oscillator (the harmonics generated by the oscillator are always outside the communication operating frequency band of the communication module 2), that is, limits the communication module 2 to operate in a specific frequency band. However, limiting the communication operating frequency band of the communication module 2 in this way makes the communication module 2 unable to operate in some communication methods, which significantly limits the performance of the communication module 2.

[0038] In order to effectively improve at least one technical problem existing in the related art, the present disclosure provides a corresponding solution.

[0039] 3 is a block diagram of an oscillation frequency control system provided by an embodiment of the present disclosure. As shown in FIG. 3, the oscillation frequency control system 3 can be applied to a display device, which includes a communication module 2 and a display driver module 1 having at least one oscillator, where the communication module can be embedded on the display driver module or fixed near the display driver module. The display driver module 1 can be installed on a flexible printed circuit (FPC) board of the display device.

[0040] The oscillation frequency control system 3 includes an acquisition module 31, an identification module 32, and a control module 33. Here, the acquisition module 31 is configured to acquire current operating information of the communication module 2, the identification module 32 is configured to identify the oscillation operating frequency corresponding to each oscillator according to the current operating information, and the control module 33 is configured to control each oscillator to operate at the corresponding oscillation operating frequency, and the frequency of the harmonic generated when each oscillator operates at the corresponding oscillation operating frequency is outside the communication operating frequency band in which the communication module 2 currently operates.

[0041] In the embodiment of the present disclosure, the oscillation operating frequency of the oscillator in the display driving module 1 is adjusted according to the current operating information of the communication module 2, so as to change the frequency of the harmonics generated when the oscillator is operating, and the frequency of the harmonics is positioned outside the communication operating frequency band in which the communication module 2 is currently operating, thereby effectively avoiding the problem of harmonics generated by the oscillator interfering with the communication module 2.

[0042] Furthermore, by adjusting the oscillation operating frequency of the oscillator, the communication operating frequency band of the communication module 2 is no longer limited, making it possible to apply the module to a variety of different communication scenarios.

[0043] In some embodiments, the oscillation frequency control system 3 can be integrated into the display driving module 1 in the form of software, that is, the oscillation frequency control system in the present disclosure can be realized by writing code into the display driving module 1, and this technical solution does not require any changes to the hardware structure, which is advantageous in reducing development costs.

[0044] Of course, those skilled in the art will understand that the oscillation frequency control system 3 in the present disclosure may exist independently of the display driver module 1.

[0045] 4A is another block diagram of an oscillation frequency control system according to an embodiment of the present disclosure. As shown in FIG. 4A, in some embodiments, the current operating information of the communication module 2 acquired by the acquisition module 31 includes the communication operating frequency band in which the communication module 2 currently operates. At this time, the identification module 32 can identify the oscillation operating frequency corresponding to each oscillator according to the communication operating frequency band in which the communication module 2 currently operates.

[0046] In some embodiments, the oscillation frequency control system 3 further includes a first storage module 36, in which the first correspondence data is stored.

[0047] Table 1 is a correspondence table of different communication operating frequency bands and corresponding frequency coordination schemes in an embodiment of the present disclosure.

[0048] [Table 1]

[0049] The first correspondence data can be represented by the correspondence table shown in Table 1 above. The first correspondence data describes different communication operating frequency bands and corresponding frequency adjustment schemes, and the frequency adjustment schemes describe oscillation operating frequencies corresponding to each oscillator. The identification module 32 is specifically configured to identify the frequency adjustment scheme corresponding to the communication operating frequency band in which the communication module 2 currently operates, using the first correspondence data.

[0050] Furthermore, according to the actual situation of the communication module 2, different communication operating frequency bands can be divided, and then a frequency adjustment scheme corresponding to each different communication operating frequency band can be obtained through a pre-experiment / simulation method. It is only necessary to position the frequency of the harmonics generated when the oscillator operates using the specified frequency adjustment scheme outside the communication operating frequency band corresponding to the specified frequency adjustment scheme.

[0051] In some embodiments, the oscillators installed in the display driver module 1 include a first oscillator and a second oscillator, where the oscillation operating frequency of the first oscillator is denoted as OSC1 and the oscillation operating frequency of the second oscillator is denoted as OSC2. As an example, when the communication operating frequency band is in the first frequency band (frequency band 1), frequency adjustment scheme 1 described in the first correspondence data is invoked, the first oscillator OSC1 is 151 MHz, and the second oscillator OSC2 is 165.4 MHz. When the communication operating frequency band is in the second frequency band (frequency band 2), frequency adjustment scheme 2 described in the first correspondence data is invoked, the first oscillator OSC1 is 151 MHz, and the second oscillator OSC2 is 170.5 MHz. When the communication operating frequency band is in the third frequency band (frequency band 3), frequency adjustment scheme 3 described in the first correspondence data is invoked, the first oscillator OSC1 is 148 MHz, and the second oscillator OSC2 is 165.4 MHz. When the communication operating frequency band is in the fourth frequency band (frequency band 4), frequency adjustment scheme 4 described in the first correspondence data is invoked, the first oscillator OSC1 is 148 MHz, and the second oscillator OSC2 is 170.5 MHz.

[0052] In some embodiments, when the first frequency band is about 943 MHz, frequency adjustment scheme 1 described in the first correspondence data is invoked, the first oscillator OSC1 is 151 MHz, and the second oscillator OSC2 is 165.4 MHz. When the second frequency band is about 1800 MHz, frequency adjustment scheme 2 described in the first correspondence data is invoked, the first oscillator OSC1 is 148 MHz, and the second oscillator OSC2 is 170.5 MHz.

[0053] In some embodiments, the communication module 2 can switch between multiple different communication operating frequency bands according to actual needs (for example, the communication module 2 supports 4G communication and 5G communication, and the communication operating frequency band of the communication module 2 can be switched between the 4G frequency band and the 5G frequency band). In this case, the oscillation frequency control system 3 further includes a frequency band detection module 35, which is configured to detect whether a change has occurred in the communication operating frequency band of the communication module 2, and, when detecting that a change has occurred in the communication operating frequency band of the communication module 2, to control the acquisition module 31 to acquire the communication operating frequency band in which the communication module 2 currently operates, and then, via the identification module 32 and the control module 33, to appropriately switch the oscillation operating frequency of the oscillator in the display driver module 1, so as to ensure that the frequency of harmonics generated when the oscillator operates is always outside the communication operating frequency band in which the communication module 2 currently operates.

[0054] As can be seen from the above, the provision of the frequency band detection module 35 can realize dynamic adjustment of the oscillation operating frequency of the oscillator, and ensure that the communication module 2 can always maintain good communication quality in different scenarios.

[0055] 4B is a block diagram of a further configuration of an oscillation frequency control system according to an embodiment of the present disclosure. As shown in FIG. 4B, in some embodiments, the oscillation frequency control system includes not only the frequency band detection module 35 and the first storage module 36, but also an interference detection module 39.

[0056] Here, the frequency band detection module 35 is configured to detect whether a change has occurred in the communication operating frequency band of the communication module 2. When the frequency band detection module 35 detects a change in the communication operating frequency band of the communication module 2, the interference detection module 39 further detects whether oscillator harmonic interference exists in the communication operating frequency band in which the communication module 2 currently operates (i.e., the communication operating frequency band after the change). When it detects that oscillator harmonic interference does not exist in the communication operating frequency band in which the communication module 2 currently operates, it establishes a correspondence between the communication operating frequency band in which the communication module 2 currently operates and the oscillation operating frequencies at which each oscillator currently operates and stores the correspondence in the first storage module. When it detects that oscillator harmonic interference exists in the communication operating frequency band in which the communication module 2 currently operates, it controls the acquisition module 31 to acquire the communication operating frequency band in which the communication module 2 currently operates. This design allows the data stored in the first storage module 36 to be continuously enriched, improving control accuracy.

[0057] 5A is a further block diagram of an oscillation frequency control system according to an embodiment of the present disclosure. As shown in FIG. 5A, in some embodiments, the current operating information of the communication module 2 acquired by the acquisition module 31 includes the communication mode currently used by the communication module 2. At this time, the identification module 32 can identify the oscillation operating frequency corresponding to each oscillator according to the communication mode currently used by the communication module 2.

[0058] Generally, the communication method of the communication module 2 has a one-to-one correspondence with the communication operating frequency band of the communication module 2. Identifying the communication method in which the communication module 2 currently operates also identifies the communication operating frequency band in which the communication module 2 currently operates, and therefore it is possible to identify the oscillation operating frequency corresponding to each oscillator based on the communication method in which the communication module 2 currently operates. Here, the communication method of the communication module 2 includes, but is not limited to, 2G communication methods (e.g., GSM (registered trademark) method, CDMA method), 3G communication methods (e.g., TD-SCDMA method, WCDMA (registered trademark) method, CDMA2000 method), WIFI communication methods, 4G communication methods (e.g., TD-LTE (registered trademark) method, TD-LTE and FDD-LTE hybrid method), and 5G communication methods.

[0059] In some embodiments, the oscillation frequency control system 3 further includes a second storage module 38, in which the second correspondence data is stored.

[0060] Table 2 is a correspondence table of different communication methods and corresponding frequency coordination schemes in an embodiment of the present disclosure.

[0061] [Table 2]

[0062] The second correspondence data can be represented by the correspondence table shown in Table 2 above. The second correspondence data describes different communication methods and corresponding frequency adjustment schemes, and the frequency adjustment schemes describe the oscillation operating frequencies corresponding to each oscillator. The identification module 32 is specifically configured to identify the frequency adjustment scheme corresponding to the communication method in which the communication module 2 currently operates using the second correspondence data.

[0063] Furthermore, the communication method that needs to be recorded in the second correspondence data can be designed based on the communication method that the communication module 2 actually supports, and then a frequency adjustment scheme corresponding to each different communication method can be obtained through a pre-experiment / simulation method. It is only necessary to position the frequency of the harmonic generated when the oscillator operates using the identified frequency adjustment scheme outside the communication operating frequency band of the communication method corresponding to the identified frequency adjustment scheme.

[0064] In some embodiments, the communication module 2 can switch between different communication methods according to actual needs (for example, the communication module 2 supports 4G communication and 5G communication, and the communication module 2 can switch between the 4G communication method and the 5G communication method, and can also switch the communication operating frequency band accordingly). In this case, the oscillation frequency control system 3 further includes a method detection module 37, which is configured to detect whether a change has occurred in the communication method of the communication module 2, and when a change has occurred in the communication method of the communication module 2, to control the acquisition module 31 to acquire the communication method currently operating in the communication module 2, and then via the identification module 32 and the control module 33, to appropriately switch the oscillation operating frequency of the oscillator in the display driver module 1, so as to ensure that the frequency of the harmonic generated when the oscillator operates is always outside the communication operating frequency band currently operating in the communication module 2.

[0065] In some embodiments, the communication method deployed in the communication module 2 includes at least one of a 2G communication method, a 3G communication method, a WIFI communication method, a 4G communication method, and a 5G communication method.

[0066] In some embodiments, the oscillators installed in the display driver module 1 include a first oscillator and a second oscillator, where the oscillation operating frequency of the first oscillator is denoted as OSC1 and the oscillation operating frequency of the second oscillator is denoted as OSC2. As an example, when the communication method is the first communication method (method 1), a frequency adjustment scheme 1' described in the second correspondence data is invoked, where the first oscillator OSC1 is 151 MHz and the second oscillator OSC2 is 165.4 MHz. When the communication method is the second communication method (method 2), a frequency adjustment scheme 2' described in the second correspondence data is invoked, where the first oscillator OSC1 is 151 MHz and the second oscillator OSC2 is 170.5 MHz. When the communication method is the third communication method (method 3), a frequency adjustment scheme 3' described in the second correspondence data is invoked, where the first oscillator OSC1 is 148 MHz and the second oscillator OSC2 is 165.4 MHz. When the communication method is the fourth communication method (method 4), the frequency adjustment scheme 4' described in the second correspondence data is called, the first oscillator OSC1 is 148 MHZ, and the second oscillator OSC2 is 170.5 MHZ.

[0067] In some embodiments, when the communication method is a first communication method (e.g., method 1=4G), a frequency adjustment scheme 1' described in the second correspondence data is invoked, the first oscillator OSC1 is 151 MHz, and the second oscillator OSC2 is 165.4 MHz. When the communication method is a second communication method (e.g., method 2=5G), a frequency adjustment scheme 2' described in the second correspondence data is invoked, the first oscillator OSC1 is 148 MHz, and the second oscillator OSC2 is 170.5 MHz.

[0068] 5B is a block diagram of a further configuration of an oscillation frequency control system according to an embodiment of the present disclosure. As shown in FIG. 5B, in some embodiments, the oscillation frequency control system includes not only the scheme detection module 37 and the second storage module 38, but also an interference detection module 39.

[0069] Here, the method detection module 37 is configured to detect whether a change has occurred in the communication method of the communication module 2. When the method detection module 37 detects a change in the communication method of the communication module 2, the interference detection module 39 further detects whether oscillator harmonic interference exists in the communication operating frequency band in which the communication module 2 currently operates (i.e., the communication operating frequency band after the communication method change). When the method detection module 37 detects that oscillator harmonic interference does not exist in the communication operating frequency band in which the communication module 2 currently operates, the interference detection module 39 establishes a correspondence between the communication method in which the communication module 2 currently operates and the oscillation operating frequency at which each oscillator currently operates and stores the correspondence in the second storage module 38. When the method detection module 37 detects the presence of oscillator harmonic interference in the communication operating frequency band after the change in the communication module 2, the acquisition module 31 is configured to control the acquisition module 31 to acquire the communication method in which the communication module 2 currently operates. This design allows the data stored in the second storage module 38 to be continuously enriched, improving control accuracy.

[0070] 6 is a configuration block diagram of a display driving module 1 in an embodiment of the present disclosure. As shown in FIG. 6, in some embodiments, the display driving module 1 further includes a driving unit and a Mobile Industry Processor Interface (MIPI) unit (also referred to as a MIPI interface unit), and the at least one oscillator includes a first oscillator and a second oscillator, where the first oscillator is used to provide a clock signal to the driving unit and the second oscillator is used to provide a clock signal to the MIPI interface unit.

[0071] Here, the driving unit generally includes a gate driving circuit (for example, a gate driving circuit for outputting a Gate signal, a gate driving circuit for outputting an EM signal, a gate driving circuit for outputting a Resst signal) and a source driving circuit.

[0072] Optionally, the first oscillator has an operating frequency of 151.7 MHz or less, and the second oscillator has an operating frequency of 151.7 MHz or more. Optionally, the second oscillator has an operating frequency range of 151.7 MHz to 192 MHz.

[0073] The oscillation operating frequency set in the first oscillator and the oscillation operating frequency set in the second oscillator may be the same or different.

[0074] Of course, the number of first oscillators in the embodiments of the present disclosure may be two or more, for example, an independent first oscillator may be arranged for each gate drive circuit, and an independent first oscillator may also be arranged for the source drive circuit.

[0075] In some embodiments, the display driving module 1 further includes a register, and the oscillators are configured to operate according to control instructions written in the register, and the control module 33 includes a writing unit, where the writing unit is configured to write corresponding control instructions to the register based on the oscillation operating frequencies corresponding to each oscillator identified by the identification module 32, so that each oscillator operates at the oscillation operating frequency corresponding to the control instruction written in the register.

[0076] Figure 7A is a conceptual diagram showing how a write unit writes into a register the control command codes used to control the first oscillator to operate at 151.7 MHz and the second oscillator to operate at 165.4 MHz. Figure 7B is a conceptual diagram showing how a write unit writes into a register the control command codes used to control the first oscillator to operate at 151.7 MHz and the second oscillator to operate at 170.5 MHz. Figure 7C is a conceptual diagram showing how a write unit writes into a register the control command codes used to control the first oscillator to operate at 148 MHz and the second oscillator to operate at 165.4 MHz. Figure 7D is a conceptual diagram showing how a write unit writes into a register the control command codes used to control the first oscillator to operate at 148 MHz and the second oscillator to operate at 170.5 MHz. As shown in Figures 7A to 7D, the writing unit can write corresponding control commands to registers in the display driving module through the MIPI interface, where OSC1 represents the oscillation operating frequency allocated to the first oscillator, OSC2 represents the oscillation operating frequency allocated to the first oscillator, OxF0 is the identifier of the first oscillator, and OxC3 is the identifier of the second oscillator.

[0077] It should be noted that FIG. 6 only schematically illustrates a situation in which two oscillators are installed in the display driving module, and this situation only serves as an example and does not limit the technical solution of the present disclosure.

[0078] In actual applications, the oscillation operating frequency of each oscillator can be set using a register within the display driver module. However, since the oscillators within the display driver module are generally RC type oscillators, there is a discrepancy between the actual oscillation operating frequency of the oscillator and the set oscillation operating frequency due to the influence of the accuracy of the trimming process and the ambient temperature. As a result, the position where harmonics are generated when the oscillator is operating differs from the expected position, and it has been found that there is a risk that the harmonics will cause resonant interference in the communication operating frequency band in which the communication module is currently operating.

[0079] Referring again to Figures 3, 4 and 5, in order to effectively improve the above technical problems, in some embodiments, the oscillation frequency control system further includes a frequency calibration module 34, which is configured to perform frequency calibration on the oscillator, so as to improve the problem of discrepancy between the actual oscillation operation frequency of the oscillator and the set oscillation operation frequency.

[0080] In practical applications, the oscillator frequency can be calibrated using the following two methods. First, since the oscillator connected to the MIPI interface of the application processor (AP) is a quartz oscillator, which has high accuracy and is not affected by stable changes, the frequency of the MIPI clock in the application processor can be used to calibrate the OSC frequency of the oscillator in the display driver module. Second, the PARAM parameters of the oscillator in the display driver module can be continuously adjusted to automatically calibrate the oscillator OSC frequency.

[0081] It should be noted that in the embodiments of the present disclosure, the frequency calibration module 34 can be integrated into the oscillation frequency control system to effectively improve the integration degree of the product, and in the embodiments of the present disclosure, the frequency calibration module 34 can also exist independently of the oscillation frequency control system.

[0082] Based on the same inventive idea, the embodiment of the present disclosure further provides an oscillation frequency control method that is applied to a display device and is based on the oscillation frequency control system provided by the previous embodiment.
