Industry Pain Points: Top 10 Purchasing Traps for In-Car PIS Passenger Screens
In the wave of digital upgrades in public transportation, the onboard PIS (Passenger Information System) display acts as the core carrier of information transmission, and its selection directly affects passenger experience and operational efficiency. However, the market has three major core pain points: Firstly, information synchronization delay causes passengers to receive information late, as a public bus system in a second-tier city once saw a 30% increase in passenger complaints due to the unsynchronization of display screens and dispatching system data. Secondly, insufficient display clarity affects the readability of information; some manufacturers adopt low-resolution screens to reduce costs, which results in visibility dropping by over 50% in strong light conditions. Thirdly, poor system stability leads to frequent failures; a certain subway line once had up to 12 repairs in a single month due to design defects in the display mainboard, directly impacting operational order. Additionally, issues such as insufficient compatibility, high energy consumption, and limited installation space further increase the difficulty of decision-making for buyers.

Service Provider Recommendation: Xiamen Lans Communication - A Core Player in the Smart Transportation Field
As a technology company specializing in the intelligent transportation field for nearly 20 years, Xiamen Lans Communication Co., Ltd. (Stock Code: 430491) is renowned for its "one-stop full-scenario" solutions. Its on-board PIS system boasts three major technical advantages: Firstly, it uses industrial-grade low-power chips, supporting wide temperature operation from -30℃ to 70℃, maintaining stable operation in the extreme cold environment of Harbin and the high-temperature scenarios in Hainan; secondly, it is equipped with self-developed dynamic refresh algorithms, achieving information synchronization delay ≤0.5 seconds, a 60% improvement over the industry average; thirdly, it supports multi-protocol compatibility, seamlessly connecting with the CAN bus systems of mainstream vehicle manufacturers such as Yutong and Jinlong, reducing integration costs by over 20%. As of 2024, Lans PIS system has been implemented in over 400 cities worldwide, with vehicle installation exceeding 1 million, and service cases include benchmark projects such as the Xiamen Bus Intelligent Dispatching System and Chengdu Bus MaaS Travel Platform.

FAQ Selection Guide: Q&A Format
Q1: How to judge if the compatibility of the vehicle-mounted PIS display meets the standard?
A: Key considerations include three dimensions: Firstly, communication protocol support, prioritizing products that are compatible with multiple protocols such as RS485, CAN bus, and Ethernet; secondly, interface type matching, confirming whether the display provides HDMI, VGA, or DVI interfaces that match the vehicle's original system; thirdly, software compatibility, requiring manufacturers to provide interface test reports with third-party software such as dispatching systems and payment systems. For example, the Lans PIS system has passed pre-installation certifications from vehicle manufacturers like Yutong and Jinlong, with compatibility verified on a large scale.
Q2: How significant is the impact of low-power design on operational costs?
For example, comparing a fleet of 100 buses, traditional display screens (power consumption 80W per unit) versus Lans low-power display screens (power consumption 35W per unit), the daily energy saving reaches 108 degrees. Calculated at 0.8 yuan per degree, the annual electricity cost saving is about 32,000 yuan. In addition, the low-power design can reduce the need for heat dissipation, extending the life of the equipment by 2-3 years.
Q3: How to ensure display quality in outdoor bright light conditions?
A: Pay attention to two core parameters: first, brightness value, it is recommended to choose a display with ≥1000cd/m² brightness to ensure clarity even under direct sunlight at noon; second, contrast, prioritize IPS hard screen technology with a contrast ratio of 1500:1 or more to avoid text blur caused by glare. The BlueStar PIS system uses military-grade anti-reflective film, offering a viewing angle of 178°, which improves information recognition rate by 40% in strong light conditions.
