[0023] Figure 1 is a schematic diagram of an intelligent low-power Mini LED backlight control system according to an embodiment of the present invention. Refer to Figure 1, an embodiment of the present invention schematically provides an intelligent low-power MiniLED backlight control system, which includes a video source module 10, an upstream connection module 20, a downstream connection module 40, a display screen module 50, an intelligent connection processing module 30, a power consumption regulation module 60, an optical drive module 70, a light control interface 80, and an intelligent remote update module 90.

[0024] The video source module 10 provides a video source signal, and specifically can provide video source signals in different playback formats.

[0025] The display screen module 50 is, for example, an LCD display screen with different resolutions, and can display videos with different resolutions according to different video source signals. The resolutions include 4K, 2K, 1080P, and 720P.

[0026] The upstream connection module 20 is associated with the downstream connection module 40, and can adapt to the communication interface types of different video source signals (such as eDP, LVDS, MIPI, VbyOne, etc. interfaces), and can be compatible with most of the video transmission protocol interface types on the market. The upstream connection module 20 is connected to the video source module 10 and the intelligent connection processing module 30. The upstream connection module 20 adapts to the communication interface type of the video source signal to transmit the video source signal to the intelligent connection processing module 30.

[0027] The downstream connection module 40 is connected to the display screen module 50 and the intelligent connection processing module 30. The intelligent connection processing module 30 can independently identify video source signals of different interface type protocols, and perform corresponding type processing on the video source signals of the corresponding interface type protocols, and provide video source data with different resolutions according to different required resolutions, so that the video source signal is compatible with the resolution of the display screen module 50, and transmits the processed video source signal to the display screen module 50 through the downstream connection module 40 for video playback.

[0028] The ways for the intelligent connection processing module 30 to process the data in the video source signal include: decoding, compression, expansion, etc. For example, when a signal of the LVDS interface type protocol is recognized, it is transferred to the LVDS protocol processing module to decode the RGB display information and synchronization information required for display in the LVDS protocol, and then after processing such as compression, expansion, or direct transmission according to the resolution required by the display screen module 50, it is sent to the display screen module 50; when a signal of the eDP interface type protocol is recognized, it is transferred to the eDP protocol processing module to decode the RGB display information and synchronization information required for display in the eDP protocol, and then after processing such as compression, expansion, or direct transmission according to the resolution required by the display screen module 50, it is sent to the display screen module 50; when a signal of the MIPI interface type protocol is recognized, it is transferred to the MIPI protocol processing module to decode the RGB display information and synchronization information required for display in the MIPI protocol, and then after processing such as compression, expansion, or direct transmission according to the resolution required by the display screen module 50, it is sent to the display screen module 50; when a signal of the VbyOne interface type protocol is recognized, it is transferred to the VbyOne protocol processing module to decode the RGB display information and synchronization information required for display in the VbyOne protocol, and then after processing such as compression, expansion, or direct transmission according to the resolution required by the display screen module 50, it is sent to the display screen module 50.

[0029] The power consumption regulation module 60 is connected to the intelligent connection processing module 30, analyzes the video source signal according to a preset power consumption regulation algorithm to obtain light control information, and the power consumption of the light control information is the lowest at present. The optical drive module 70 is connected to the power consumption regulation module 60 and controls the light of the intelligent light partition board 100 according to the light control information. Specifically, the optical drive module 70 is connected to the intelligent light partition board 100 through the optical drive interface, and the light control interface 80 is compatible with the communication protocols of the optical drive module 70 and the intelligent light partition board 100 respectively to transmit the light control information to the intelligent light partition board 100.

[0030] The power consumption regulation algorithm includes a neural network model, an optoelectronic transfer function, and a backlight power consumption budget control strategy. Specifically, based on the neural network algorithm, the important areas (such as the middle area) of the intelligent light partition board are judged, and the brightness of the key areas is preferentially retained. Then, through the optoelectronic transfer function (such as the PQ (Perceptual Quantizer) type in the optoelectronic transfer function) and the brightness range metadata (such as dynamic metadata), the real brightness is perceived, and the combination of the dynamic backlight budget pool and the local priority compression backlight power consumption budget control strategy is combined, and it complements the optical drive module.

[0031] Generally, the intelligent light control partition board 100 has multiple light control partition units. The light control information includes multiple partition light control data, and the partition light control data corresponds to the light control partition units one by one. The optical drive module 70 independently controls the light of the multiple light control partition units of the intelligent light control partition board 100 according to the partition light control data. That is, the intelligent connection processing module 30 can generate partition light control data corresponding to the multiple light control partition units one by one after processing the video source signal, and the power consumption of each partition light control data is the lowest at present, so as to achieve the overall low power consumption of the system. The light control information includes voltage information, current information, brightness information, etc. That is, the partition light control data includes voltage information, current information, brightness information, etc. Each light control partition unit has multiple Mini LEDs, that is, the Mini LEDs in each light control partition unit are controlled for light.

[0032] Based on the neural network algorithm to judge the important area, the key area brightness is preferentially retained. Through the photoelectric transfer function (PQ + dynamic metadata) and the brightness range metadata, it can be used to perceive the real brightness, the dynamic backlight budget pool and the local priority compression backlight power consumption budget control strategy, and complements the optical drive module.

[0033] In this way, the intelligent connection processing module 30 can analyze the data in different video source signals according to the adaptive power consumption regulation algorithm to obtain low-power independent partition light control data, and transmit it to the optical drive module 70 to realize the low-power adjustment of real-time dynamic independent partition light control. According to the requirements of different independent partition numbers, the video source data is analyzed for each independent light control partition unit, as well as the local independent light control partition unit (such as 4*4 according to actual requirements), and all the independent light control partition units as a whole. The adaptive power consumption regulation algorithm is used to obtain the lowest and most suitable partition light control data for each independent light control partition unit. The design of the power consumption regulation module 60 can save the system power consumption in real-time, intelligently and dynamically adaptively.

[0034] The intelligent remote update module 90 is used to update and iterate the intelligent connection processing module 30, the power consumption regulation module 60 and the optical drive module 70. In the test products or finished equipment, the entire system can be updated and iterated in real-time through the intelligent remote update module 90, without the need to disassemble it to update the system, saving manpower and material resources.

For any person skilled in the art, without departing from the scope of the technical solution of the present invention, many possible changes and modifications can be made to the technical solution of the present invention by using the technical content disclosed above, or it can be modified into equivalent embodiments with equivalent changes.
