C, outdoor LCD display screen with battery signboard machine -50℃~110℃ wide temperature adaptation: stable operation at extreme temperature.
Core technical support for wide temperature design: In view of outdoor extreme temperature environment, the LCD display screen of outdoor battery signboard machine adopts dual cooling system of "active heat dissipation+passive heat dissipation"-in high temperature environment, the heat generated by the backlight module of LCD display screen of main board and outdoor battery signboard machine can be quickly exported by the air-cooled structure cooling fan (adjustable speed) combined with aluminum military-grade cooling substrate, and the temperature of internal core components can be controlled at 65℃ even under high temperature exposure of 110℃. In the low temperature environment, the backlight module of the LCD display screen of outdoor signboard machine with battery has a built-in heater, which can raise the core temperature of the screen to above 0℃ within 5 minutes after power-on, so as to realize quick start at-50℃ and avoid the afterimage and response delay of the LCD screen due to low temperature.

Environmental adaptability supplement: except temperature, outdoor LCD display screen equipment with battery signboard machine can operate in 10%~90% humidity (no condensation). In southern rainy season and coastal humid areas, the internal moisture-proof coating can isolate moisture and prevent short circuit of circuit board; After high and low temperature cycle test (repeated switching at -50℃~110℃ for 1000 times), the whole machine has no attenuation, which ensures the stability of long-term outdoor use and reduces the failures caused by environmental factors.

Endurance of 50,000 mAh blade battery: equipped with 50,000 mAh large-capacity blade battery, it can meet the demand of 14-hour continuous work after 7 hours of charging (calculated by playing 1080P video with medium brightness), without external power supply, and the LCD display screen of outdoor machine with battery signboard is suitable for outdoor scenes without power supply conditions (such as temporary exhibitions and open-air markets); The battery supports 24V input voltage, has overcharge, overdischarge and overcurrent protection, and has no risk of bulging and leakage after long-term use. Its service life is synchronized with the screen (about 60,000 hours), which reduces the cost of battery replacement in the later period.
