Description

Technical Field

[0001] The present invention relates to the technical field of display control, and in particular, to a control circuit for gravity-sensing adaptive display and a portable display. Background Art

[0002] In the prior art, some display manufacturers have launched display products that support the gravity-sensing function. Such displays need to add a gravity-sensing switch on the device and combine with a dedicated software (such as DisplayWidget) installed on the computer side to achieve automatic switching of the display mode. Specifically, when the user switches the display to the landscape mode, the gravity-sensing switch detects the landscape state and transmits the state signal to the computer side through the main control chip of the display and the video cable connected to the computer. After the dedicated software on the computer side reads the state signal, it controls the computer to adjust the video signal output to the external display to 0 degrees or 180 degrees. Similarly, when the user switches the display to the portrait mode, the gravity-sensing switch detects the portrait state and transmits the state signal to the computer side, and then the software controls the computer to adjust the video signal to 90 degrees or 270 degrees, so as to achieve the gravity-sensing horizontal and vertical screen adjustment function of the display.

[0003] However, there are certain limitations in the gravity-sensing screen switching technology of existing display products: First, the user needs to install dedicated software on the computer side to achieve the switching of the display mode, which increases the complexity and dependence of the user operation; Second, the state signal of the gravity-sensing switch needs to be transmitted to the computer side through the video cable, which may have problems such as signal delay or unstable transmission.

The following will be described in detail respectively.

[0057] Embodiment 1

[0058] Please refer toFigure 1 , Figure 1 is a schematic structural diagram of a control circuit for gravity - sensing adaptive display disclosed in an embodiment of the present invention. Among them, Figure 1 the described control circuit for gravity - sensing adaptive display can be applied to a portable display or a conventional desktop display, and the embodiments of the present invention do not make any limitations. As Figure 1 shown, the control circuit for gravity - sensing adaptive display may include a display main control chip 10, a display input module 20, a display switching module 30, and a display output module 40, where:

[0059] The first end of the display main control chip 10 is electrically connected to the first end of the display input module 20; the second end of the display main control chip 10 is electrically connected to the first end of the display switching module 30; the third end of the display main control chip 10 is electrically connected to the first end of the display output module 40;

[0060] The first end of the display input module 20 is used to access a target input signal; the second end of the display output module 40 is used to externally connect to a target device; the target input signal includes at least one of a video signal, a control instruction for the display main control chip 10, and a power signal; the target device includes at least a display device;

[0061] The display main control chip 10 is configured to, after detecting the target input signal transmitted by the display input module 20, perform a preset display process on the target input signal, and transmit the corresponding display process signal to the target device to display the display process signal through the target device;

[0062] The display main control chip 10 is further configured to, when determining that the current meets a preset display switching condition, generate a display switching instruction, and switch the display mode of the target device according to the display switching instruction, where the display mode includes a landscape mode or a portrait mode;

[0063] Among them, meeting the display switching condition at least includes that the display main control chip 10 detects a state change of the display switching module 30, and the state change of the display switching module 30 is an operation performed by the display switching module 30 according to its current gravity - sensing result.

[0064] In an embodiment of the present invention, the target device may further include an audio playback device, such as a speaker SPK.

[0065] It can be seen that implementing Figure 1The described control circuit for gravity-sensing adaptive display, in addition to realizing the conventional display function, through the gravity-sensing function of the display switching module, can detect the attitude change of the control circuit in real time. At the same time, combined with the fast response ability of the display main control chip, it realizes seamless switching between landscape and portrait display modes, and improves the response speed of horizontal and vertical screen switching. Among them, the display switching module directly triggers the state switching based on the gravity-sensing result and transmits it to the display main control chip through a hardware signal, which is different from the traditional gravity-sensing implementation method that requires additional downloading of specific software. This control circuit can effectively avoid the delay and misjudgment problems existing in the software judgment method of the traditional method, making the switching delay as low as the millisecond level, improving the switching reliability and switching response speed of this display mode switching, and at the same time being conducive to improving the convenience and user experience of using this control circuit by users.

[0066] In an alternative embodiment, as Figure 2 shown, Figure 2 is a schematic structural diagram of another control circuit for gravity-sensing adaptive display disclosed in an embodiment of the present invention. As Figure 2 shown, the display switching module 30 includes a gravity-sensing sub-module 301, an electronic switching sub-module 302, and a storage sub-module 303, where:

[0067] The first end of the gravity-sensing sub-module 301 is electrically connected to the second end of the display main control chip 10; the first end of the electronic switching sub-module 302 is electrically connected to the second end of the display main control chip 10; the second end of the electronic switching sub-module 302 is electrically connected to the first end of the storage sub-module 303;

[0068] The gravity-sensing sub-module 301 is configured to collect gravity-sensing information of the target device and generate a gravity control instruction matching the gravity-sensing information;

[0069] The gravity-sensing sub-module 301 is further configured to perform on-off control on the gravity-sensing sub-module 301 according to the gravity control instruction, obtain an on-off control result corresponding to the gravity-sensing sub-module 301, and at the same time feedback the on-off control result to the display main control chip 10;

[0070] The display main control chip 10 is further configured to generate a first switching instruction according to the on-off control result and transmit the first switching instruction to the electronic switching sub-module 302;

[0071] The electronic switching sub-module 302 is configured to determine a target resolution matching the first switching instruction from the storage sub-module 303 and feedback the target resolution to the display main control chip 10, so as to switch the display mode of the target device to a display mode matching the target resolution through the display main control chip 10.

[0072] In this alternative embodiment, by configuring the gravity sensing sub-module, the gravity sensing information of the target device can be collected in real time, and gravity control instructions can be automatically generated based on this information. This mechanism enables the switching of the display mode to no longer rely on manual operations by the user, but can be automatically adjusted according to the actual usage status of the device, achieving the intelligence and automation of display switching. Also, through the on / off control function of the gravity sensing sub-module, its working status can be adjusted in real time according to the gravity control instructions, and the on / off control result can be promptly fed back to the display main control chip. This dynamic adaptability ensures that the display switching module can quickly respond to the gravity changes of the device, and then adjust the display mode to adapt to different usage scenarios.

[0073] In this alternative embodiment, the collaborative work of the electronic switching sub-module and the storage sub-module can quickly find the target resolution that matches the first switching instruction from the pre-stored resolution data. This high-resolution matching mechanism ensures that the display mode of the target device can accurately match the required resolution, thereby providing a clearer and more delicate display effect.

[0074] In this alternative embodiment, further, please refer to Figure 3 , Figure 3 FIG. is a schematic structural diagram of a gravity sensing sub-module disclosed in an embodiment of the present invention. As shown in Figure 3 shown, the gravity sensing sub-module can specifically be the structure of a gravity sensing switch. By switching the different contact situations between contact 2 and contact 1 or 3 in switch K3, the on / off state of the gravity sensing switch is adjusted, that is, the on / off state of the gravity sensing sub-module is adjusted.

[0075] It can be seen that in this alternative embodiment, the display switching module realizes the intelligent switching of the display mode based on the gravity sensing information by integrating the gravity sensing sub-module, the electronic switching sub-module, and the storage sub-module, significantly improving the display flexibility, display accuracy, and practicality of the target device (such as an electronic device).

[0076] In another alternative embodiment, the storage sub-module 303 includes a first storage unit 3031 and a second storage unit 3032, where:

[0077] The first end of the first storage unit 3031 is electrically connected to the second end of the electronic switching sub-module 302; the first end of the second storage unit 3032 is electrically connected to the second end of the electronic switching sub-module 302;

[0078] The display main control chip 10 is configured to generate a first instruction for the first storage unit 3031 as the first switching instruction when the on / off control result indicates that the gravity sensing sub-module 301 is in the off state;

[0079] The display main control chip 10 is further configured to generate a second instruction for the second storage unit 3032 as a first switching instruction when the on-off control result indicates that the gravity sensing sub-module 301 is in an on state;

[0080] The electronic switching sub-module 302 is configured to select, as the target resolution, a resolution that matches the first instruction from among the multiple first resolutions stored in the first storage unit 3031 when the first switching instruction is the first instruction;

[0081] The electronic switching sub-module 302 is further configured to select, as the target resolution, a resolution that matches the second instruction from among the multiple second resolutions stored in the second storage unit 3032 when the first switching instruction is the second instruction;

[0082] All the first resolutions match the first reference resolution; all the second resolutions match the second reference resolution; the first reference resolution is used to adapt to the landscape screen mode, and the second reference resolution is used to adapt to the portrait screen mode.

[0083] In this optional embodiment, the first reference resolution may be 16:9; correspondingly, all the first resolutions that match the first reference resolution may be 3840*2160, 2560*1440, 1920*1080; the second reference resolution may be 9:16; correspondingly, all the second resolutions that match the second reference resolution may be 2160*3840, 1440*2560, 1080*1920.

[0084] It can be seen that in this optional embodiment, through the collaborative work of the gravity sensing sub-module and the electronic switching sub-module, the control circuit can automatically select an appropriate resolution according to the landscape or portrait state of the device. This intelligent switching mechanism ensures that the displayed content can be presented at the best resolution in different screen modes, which is beneficial to improving the switching accuracy, reliability, and practicality of the screen display based on the control circuit.

[0085] In this optional embodiment, optionally, the display main control chip 10 is further configured to generate a second switching instruction according to the display switching requirement after detecting the display switching requirement for the target device, and transmit the second switching instruction to the electronic switching sub-module 302; wherein, the display switching requirement includes a landscape display requirement or a portrait display requirement; the second switching instruction includes a landscape display instruction that matches the landscape display requirement or a portrait display instruction that matches the portrait display requirement;

[0086] The electronic switching sub-module 302 is configured to determine a target storage device that matches the second switching instruction from one or more storage devices included in the storage sub-module 303, obtain a resolution that matches the second switching instruction from the target storage device as the target resolution, and feedback the target resolution to the display main control chip 10, so as to switch the display mode of the target device to a display mode that matches the target resolution through the display main control chip 10;

[0087] The instruction execution priority of the second switching instruction is higher than the instruction priority of the first switching instruction; when the first switching instruction and the second switching instruction exist simultaneously, only the second switching instruction is executed; and, after a preset recording period for executing the second switching instruction, and only when the first switching instruction is detected, the first switching instruction is allowed to be executed.

[0088] In this optional embodiment, the display switching requirement may be a control instruction triggered by the user according to the current actual requirement, such as an instruction for screen switching generated by the control program of the control circuit, which is not limited in the embodiments of the present invention.

[0089] In this optional embodiment, optionally, when the storage sub-module includes only one storage device, the storage device includes at least two storage locations, one of which is used to store multiple landscape screen resolutions that match the landscape screen display instruction; the other is used to store multiple portrait screen resolutions that match the portrait screen display instruction;

[0090] When the storage sub-module 303 includes multiple storage devices, each storage device is only used to store multiple landscape screen resolutions that match the landscape screen display instruction, or is used to store multiple portrait screen resolutions that match the portrait screen display instruction.

[0091] In this optional embodiment, it should be noted that, according to the actual configuration of the storage sub-module, the number of deployed storage devices will vary. When only one storage device is deployed in a storage sub-module, the information of the multiple landscape screen resolutions and portrait screen resolutions can be deployed in different segment storage locations of the storage device. For example, for a general EDID with 256KB of byte information, a 2M-byte EEPROM device can be selected. Resolutions with a 16:9 ratio, such as 3840*2160, 2560*1440, 1920*1080, etc., are stored in the 0-0XFF address, while resolutions with a 9:16 ratio, such as 2160*3840, 1440*2560, 1080*1920, etc., are stored in the 0X0100-0X01FF. The specific storage locations of the landscape screen resolutions and portrait screen resolutions are not limited in the embodiments of the present invention.

[0092] In this alternative embodiment, when multiple storage devices are deployed in the storage sub-module, taking the deployment of only two storage devices as an example, at this time, one storage device is only used to store all the landscape screen resolutions, and the other storage device is only used to store all the portrait screen resolutions; when a second switching instruction is detected, the resolution type to be adjusted currently is determined according to the second switching instruction, so as to locate the target memory that matches the resolution type from the two storage devices, and then determine the adapted target resolution from the multiple resolutions (landscape screen resolution or portrait screen resolution) included in the target storage device.

[0093] It can be seen that in this alternative embodiment, in addition to the screen switching mechanism based on the gravity sensing sub-module, a mechanism for responding to the user's real-time display switching requirement is also set up. Specifically, it can intelligently detect the display switching requirement, and after detecting the display switching requirement, automatically generate a corresponding second switching instruction and respond to the second switching instruction; that is, the control circuit expands a flexible adjustment scheme for the user to switch the screen display in addition to gravity sensing, enabling the user to flexibly switch between horizontal and vertical arrangements according to actual needs, and improving the flexibility of the user to use the control circuit.

[0094] In this alternative embodiment, further, please refer to Figure 4 , Figure 4 is a schematic structural diagram of a storage sub-module disclosed in an embodiment of the present invention. The Figure 4 includes two storage devices, namely the EEPROM AT24C02 of ISC3 and ISC5; when there is a second switching instruction, the target storage device can be determined according to the second switching instruction. Specifically, by pulling up the A2 pin of the ICS3 device, when reading the ICS3 device, the IIC first sends the device address 0XA9; or by pulling down the A2 pin of the ICS5 device, when reading the ICS5 device, the IIC first sends the device address 0XA1.

[0095] In yet another alternative embodiment, the display switching module 30 further includes a button switching sub-module 304, where:

[0096] The first end of the button switching sub-module 304 is electrically connected to the second end of the display main control chip;

[0097] The button switching sub-module 304 is used to generate a button switching requirement after the user triggers the button switching sub-module 304 and transmit the button switching requirement to the display main control chip 10;

[0098] The display switching requirement includes a button switching requirement and a software switching requirement, and the software switching requirement is generated by the internal program of the display main control chip 10.
