Mga Interface at Paraan ng Koneksyon ng Vertical Advertising Display

Ang patayong display ng advertising na may AUO OLED panel na binuo ng Guangzhou Ruiguan Electronic Equipment Co., Ltd. ay nilagyan ng masaganang mga opsyon sa interface, na nagbibigay sa mga user ng nababaluktot at magkakaibang mga solusyon sa koneksyon. Gamit ang kumpletong disenyo ng interface at matatag na pagganap ng paghahatid ng signal, maaaring matugunan ng device ang mga kumplikadong kinakailangan sa iba't ibang mga sitwasyong pangkomersyal na aplikasyon.

Para sa mga interface ng video input, nagtatampok ang display ng advertising ng tatlong HDMI 1.3 port na sumusuporta sa full HD na input ng signal mula 480i hanggang 1080P. Ang mga HDMI port ay gumagamit ng karaniwang Type A na 19-pin na disenyo, na sumusuporta sa hanggang 4K na resolution na transmission habang tugma sa Audio Return Channel (ARC) function. Ang bawat interface ng HDMI ay sumasailalim sa mahigpit na pagsubok sa integridad ng signal upang matiyak na walang pagpapahina ng signal sa loob ng 5 metrong distansya ng transmission. Nananatili rin ang device ng 15-pin D-SUB VGA port na sumusuporta sa maraming display mode mula sa DOS hanggang WUXGA, na may pahalang na frequency na 30-80KHz at vertical frequency na 56-75Hz, na nakakatugon sa mga kinakailangan sa koneksyon ng mga tradisyonal na device. Ang VGA port ay gumagamit ng proseso ng gold-plating upang maiwasan ang oksihenasyon at matiyak ang pangmatagalang katatagan.

For audio connections, the device provides multiple flexible solutions. Besides the audio transmission function through HDMI, it also has dedicated PC audio input and AV audio input ports. The 3.5mm stereo earphone jack can connect external monitoring devices, while the dual 3W stereo speaker system with 8Ω impedance design offers a frequency response range of 80Hz-20KHz, delivering clear and full sound effects. The audio circuit adopts professional operational amplifier chips with signal-to-noise ratio over 90dB, ensuring pure sound without background noise.

Network connection is one of the highlights of this advertising display. The RJ45 Ethernet port supports 10/100M auto-negotiation, with built-in hardware network protocol stack enabling remote content updates and device management. Through dedicated CMS system, users can centrally control multiple devices simultaneously. The COAX interface supports DVB-T2/S2 digital TV signal reception, and with the built-in demodulation chip, can directly play digital TV programs.

For power design, the advertising display adopts wide voltage input (AC 90-220V, 50-60Hz) with built-in high-efficiency switching power module achieving over 90% conversion efficiency. The DC12V power input uses 4P*2.0 red pin socket design with reverse connection protection function. The power management system supports low-power mode and standby mode, with standby power consumption controlled below 0.5W, complying with the latest energy efficiency standards.

The USB ports adopt horizontal design with two USB 2.0 Host interfaces supporting hot-plug and plug-and-play. The ports have built-in overcurrent protection circuit with maximum output current of 1A per port, meeting power supply requirements of most external devices. The file system supports FAT32/NTFS/exFAT formats with maximum 2TB storage device compatibility, working with various USB drives and mobile hard disks.

The LVDS screen interface uses 2*15PIN 2.0mm pitch design supporting dual-channel transmission, ensuring no delay for 1920×1080 resolution images. The interface adopts double locking mechanism to prevent loosening during transportation. The signal transmission lines use differential pair design to effectively suppress electromagnetic interference and ensure image purity.

The AV input/output ports adopt composite video signal design supporting PAL/NTSC auto-identification. The two AV input channels can connect surveillance cameras and other devices, facilitating simple monitoring system setup. The AV output port can cascade multiple devices to expand display range.

For control interfaces, the device supports RS-232 serial port control, enabling remote power on/off, volume adjustment and other functions through standard AT command set. The front panel buttons use high-quality micro switches with lifespan over 100,000 times, providing basic operations like power, menu, and volume adjustment.

The overall interface layout is carefully designed with all ports concentrated in the back recess, ensuring both connection convenience and neat appearance. Each interface has clear labeling and comes with dust-proof cover to prolong service life.
