Description

Technical Field

[0001] This invention relates to the field of LCD liquid crystal module technology, specifically to an outdoor dynamic backlight energy-saving LCD liquid crystal module. Background Technology

[0002] LCD modules are the core components of outdoor display devices. Their display effect, power consumption, lifespan, and environmental adaptability directly determine the user experience and total life cycle operating cost of outdoor display devices. They are widely used in public and commercial display scenarios such as outdoor electronic bus stop signs, advertising screens, and traffic guidance screens.

[0003] To ensure basic visibility in strong light environments, traditional outdoor LCD modules generally employ high-power backlight hardware structures and lack refined local dimming designs. This not only results in low backlight contrast and poor image layering but also leads to high overall power consumption. Some traditional modules even struggle to achieve a display brightness of 2500 cd / ㎡ under strong light, resulting in poor outdoor visibility. Furthermore, the backlight driver components of traditional modules often use ordinary FR-4 PCB boards, which have poor thermal conductivity and are prone to high-temperature failures. Most require additional cooling fans, heat sinks, and other auxiliary cooling structures, further increasing power consumption and hardware costs, creating a vicious cycle of "high power consumption - high heat dissipation - even higher power consumption."

[0004] Traditional outdoor LCD panels are not designed with a dedicated structure to protect against ultraviolet and infrared radiation. In strong outdoor radiation environments, the optical coating of the panel is prone to aging and the liquid crystal layer is prone to deterioration. This not only leads to a rapid decline in display quality but also exacerbates panel temperature rise, significantly shortening the panel's lifespan and increasing the replacement and maintenance costs of the equipment. Furthermore, the backlight brightness of traditional modules can only be manually adjusted without a precise light-sensing adaptive control mechanism, which can easily result in overly bright or overly dark displays, generating a large amount of ineffective energy consumption.

[0005] In addition, traditional outdoor LCD modules are designed with a high-power architecture and are highly dependent on 24-hour power supply. In remote suburbs, rural areas and other outdoor areas without 24-hour power supply, they cannot achieve stable power supply and have extremely poor adaptability. In areas with 24-hour power supply, the engineering cost of long-distance power line construction is high, and the huge electricity expenses caused by the high power operation of the modules put a heavy cost pressure on the operators.

[0006] Meanwhile, traditional modules lack professional dynamic image processing algorithms, which can easily cause problems such as stuttering, ghosting, and low frame rate when displaying dynamic images, making them unable to meet the dynamic display needs of scenarios such as outdoor advertising and traffic guidance. Some modules also mistakenly adopt a high-level waterproof design for the module body, which not only increases manufacturing costs but also reduces the ease of maintenance of the equipment.

[0007] With the country vigorously promoting the development strategy of energy conservation and emission reduction, the high power consumption, high cost, and low adaptability of traditional outdoor LCD modules can no longer meet the requirements of industry development and national strategy. Developing an outdoor LCD module that combines high brightness, low power consumption, high protection, long life, and can be adapted to solar power supply, significantly reducing the cost of power line construction and operation and maintenance, and can completely replace traditional modules and conform to the national energy conservation strategy has become an urgent technical problem to be solved in this field.

[0027] The components are electrically connected via weather-resistant cables. The module is waterproofed as a whole by relying on the outdoor mounting enclosure, eliminating the need for a high-level waterproof structure on the module itself.

[0028] In this embodiment, the outdoor high-transparency anti-glare and anti-ultraviolet infrared LCD liquid crystal display panel 1 is an outdoor low-power panel, which is composed of an outdoor anti-scratch polarizer, a liquid crystal layer, an outdoor high-transparency color filter layer, an anti-ultraviolet infrared coating and an anti-glare protective layer stacked in sequence, and adjacent outdoor anti-scratch polarizers are orthogonally arranged.

[0029] The panel has a light transmittance of ≥90%, an anti-glare rating of AG3, and a temperature resistance range of -30℃ to 70℃. Its power consumption is reduced by more than 30% compared to traditional outdoor LCD panels.

[0030] The UV and infrared protection coating blocks outdoor ultraviolet and infrared radiation to slow down the aging of the panel's optical coating and liquid crystal layer, and reduce panel temperature rise. The pixel zones of this panel correspond 1:1 with the smaller zones of the zone-linked backlight module.

[0031] Regarding the aluminum substrate PCB-driven zoned backlight module used in this technical solution, this module is the backlight unit of the module, closely attached to the backlight side of the outdoor high-transmittance, anti-glare, anti-ultraviolet and infrared LCD display panel 1, and adopts a structure of nested linkage between large and small zones. For modules with sizes ranging from 32 to 86 inches, the total number of zones in this module is 1024 to 4096.

[0032] Specifically, the zone-linked backlight module consists of a Mini-LED light-emitting sub-unit, an aluminum substrate PCB, an outdoor high-uniformity anti-glare optical diffusion layer 2, and an independent constant current drive circuit.

[0033] The aluminum substrate PCB serves as the heat dissipation structure for this module, and the Mini-LED light-emitting sub-units are mounted on the heat-conducting surface of the aluminum substrate PCB.

[0034] The aluminum substrate PCB is an integrated outdoor corrosion-resistant structure. Its surface is anodized and coated with an anti-oxidation coating. It has a thermal conductivity of ≥2.0W / (m·K) and a temperature range of -40℃ to 85℃. It is used to conduct and dissipate the working heat of the zoned linkage backlight module.

The maximum display brightness in strong outdoor light environments is ≥2500 cd / m². An outdoor high-uniformity anti-glare optical diffusion layer 2 is disposed between the Mini-LED light-emitting sub-units and the outdoor high-transmittance anti-glare and UV-resistant infrared LCD display panel 1.

The light sensor 4 is used to collect the light intensity parameters of the outdoor environment in real time and transmit these parameters to the integrated external power supply driving the dynamic image algorithm board 5.

[0037] The integrated external power supply-driven dynamic image algorithm board 5 serves as the control and drive unit of the module. It is located on the outside of the module housing 7 and communicates with the outdoor high-transparency, anti-glare, UV-resistant, and infrared-resistant LCD display panel 1 and the zone-linked backlight module via weather-resistant cables. This algorithm board adopts a standardized outdoor interface.

[0038] Specifically, the integrated external power supply-driven dynamic image algorithm board 5 integrates a power drive circuit, an energy-saving control algorithm module, a dynamic image processing algorithm module, an image feature extraction unit, a lighting data processing unit, an algorithm calculation core unit, a dual-channel synchronous drive output unit, a precise power supply management unit, and a dynamic image processing unit. Its overall power consumption is reduced by more than 40% compared to traditional outdoor LCD driver boards. The drive output delay of the dual-channel synchronous drive output unit is <3ms.

[0039] This algorithm board supports both real-time adaptive light-sensing adjustment and timed preset adjustment. The two schemes are switched via physical buttons, with a switching response latency of <100ms. Specifically: In the real-time adaptive light-sensing adjustment scheme, the energy-saving control algorithm module and the dynamic image processing algorithm module work together: the light data processing unit normalizes the light parameters collected by the light sensor 4; the image feature extraction unit extracts the frame-by-frame brightness features and dynamic motion features of the panel image; the algorithm operation core unit outputs control parameters based on the normalized light parameters and the extracted image features to synchronously adjust the brightness of the zone-linked backlight module and the dynamic image processing parameters.

[0040] In the timed preset adjustment scheme, multiple sets of dimming parameters and dynamic image processing parameters are preset through the interactive interface.

[0041] The precision power supply management unit is used to provide time-sharing, zone-based, and power-based power to the zone-linked backlight modules according to the control parameters. The dynamic image processing unit is used to perform frame rate optimization, motion compensation, and ghosting elimination.

[0042] This embodiment also provides an outdoor energy-saving LCD module with dynamic backlight for a 32-inch outdoor electronic bus stop sign, including an outdoor high-transparency anti-glare and anti-ultraviolet infrared LCD display panel, a zone-linked backlight module driven by an aluminum substrate PCB, a light sensor, and an integrated external power supply to drive the dynamic image algorithm board.

[0043] Wherein: the light transmittance of the display panel is 91%, the anti-glare level is AG3, and its pixel partitions correspond 1:1 with the small partitions of the partition-linked backlight module; The total number of zones in the zone-linked backlight module is 1024. Its Mini-LED light-emitting sub-units are mounted on the heat-conducting surface of the aluminum substrate PCB. The maximum display brightness of the Mini-LED is 2600 cd / ㎡. The thermal conductivity of the aluminum substrate PCB is 2.2 W / (m·K), and the temperature resistance range is -40℃ to 85℃. The light sensor is an outdoor high-sensitivity type, with a light acquisition error of ±1.5% and a data transmission delay of 3ms; The integrated external power supply drives the dynamic image algorithm board with a dual-channel synchronous drive output delay of 2ms. The algorithm board adopts an outdoor standardized interface and can directly replace the power drive board of a traditional 32-inch outdoor electronic bus stop LCD module.

[0044] The module in this embodiment has a low-power architecture and can be directly adapted to a solar power system.

[0045] The outdoor energy-saving LCD module with dynamic backlight of the present invention operates as follows: First, the light sensor 4 collects the light intensity parameters of the outdoor environment in real time and transmits the collected light data to the integrated external power supply to drive the dynamic image algorithm board 5.

[0046] Secondly, the integrated external power supply drives the illumination data processing unit within the dynamic image algorithm board 5 to normalize the illumination parameters. Simultaneously, the image feature extraction unit extracts frame-by-frame brightness and dynamic motion features from the outdoor high-transparency, anti-glare, and UV- and infrared-resistant LCD display panel 1. Based on the normalized illumination parameters and extracted image features, the algorithm's core unit outputs control parameters through built-in energy-saving and dynamic image processing algorithms.

[0047] Next, the dual-channel synchronous drive output unit transmits the control parameters synchronously to the zone-linked backlight module and the display panel with a delay of <3ms, realizing the graded dimming of the zone-linked backlight module and the coordinated matching of the panel display. At the same time, the precision power supply management unit provides time-sharing, zone-based, and power-based power supply to the zone-linked backlight module according to the control parameters; the dynamic image processing unit performs frame rate optimization, motion compensation, and ghosting elimination processing on the panel image.

[0048] When the operating temperature of the zone-linked backlight module is ≥45℃, the algorithm processing core unit automatically triggers the temperature control strategy. This uses an integrated external power supply to drive the dynamic image algorithm board 5 to perform frequency and power reduction processing on non-core display areas, and optimizes the frame rate. The aluminum substrate PCB dissipates the module's operating heat.

[0049] During operation, the module of the present invention achieves high brightness display under low power drive through the synergy of the above components, and can be directly adapted to solar power supply systems.
