Import 4.3 Inch Car Monitor — Buy in Bulk from Supplier in China

Shenzhen Ph Auto Electronics offers a 4.3 inch car monitor built around a TFT LCD panel with a native resolution of 480 by 234 pixels, compatible with both PAL and NTSC composite video standards. The unit switches automatically to the reversing camera input when the vehicle engages reverse gear, a feature triggered by the reverse lamp circuit. Dual AV inputs allow simultaneous connection of a rear-view camera and an additional video source such as a media player or second camera. The nominal supply voltage is 12 V DC, aligned with standard automotive electrical systems. The 480 x 234 resolution places this model in the entry-level segment of aftermarket vehicle monitors, where cost sensitivity often outweighs pixel density for basic reversing assistance.

The TFT LCD technology provides faster response and better contrast than older CSTN alternatives, though the 480 x 234 resolution uses non-square pixels that can affect aspect ratio interpretation of 16:9 camera feeds. PAL/NTSC auto-detection removes manual configuration but introduces a brief sync delay on input change. The automatic switching logic is typically wired to the reverse light positive line, drawing a small sense current to trigger the relay or solid-state switchover. Dual AV inputs are usually RCA composite (CVBS) connectors, standard for consumer automotive video. Typical 4.3 inch car monitors in this class draw 4 to 7 watts depending on backlight level and audio amplifier inclusion, though this particular model does not advertise audio output.

Target customers include automotive aftermarket distributors, fleet operators outfitting delivery vehicles, and commercial truck upfitters who need basic visual assistance without integrated navigation complexity. The 12 V compatibility covers passenger cars and light commercial vehicles; heavy truck applications at 24 V would require an external voltage converter. Shenzhen Ph Auto Electronics is listed with imported supplier tier and harbor trust tier status, but no response data is available. Pricing, MOQ, lead time, and certificate status are not specified in the source. Buyers should confirm whether the monitor meets E-mark (ECE R10) electromagnetic compatibility or other regional automotive compliance requirements before bulk commitment.

Shenzhen Ph Auto Electronics Co., Ltd. operates from Shenzhen, Guangdong, China, postal code 518000. The supplier carries an imported tier designation alongside a harbor trust tier, which indicates the profile was migrated or imported from another source with baseline verification rather than platform-native auditing. Response metrics show 0.00 percent response rate and zero average response hours, meaning no enquiry response data exists in the current profile. Buyers should therefore initiate contact with tempered expectations and request direct communication records to assess responsiveness.

The company profile visible in the source does not state year of establishment, employee count, factory ownership, revenue, client list, or quality system certifications such as IATF 16949 or ISO 9001. The product focus implied by this listing is aftermarket automotive electronics, specifically budget-oriented display monitors for reversing and auxiliary video applications. Importers should request a company introduction, factory audit capability, and reference customers before committing to volume orders, since the available data does not independently verify manufacturing depth or automotive-specific quality processes.
