The company is especially dedicated to customizing LCD screens and modules for its clients. Products manufactured by the company, such as segment-type, character dot matrix, graphic dot matrix LCD modules, and TFT display modules, are widely used in household appliances, automotive electronics, medical equipment, industrial instruments, and other fields. Since LCD module products are precision optoelectronic products, the following precautions should be observed during use: Usage Precautions Installation and Fixing The LCD panel is composed of two very thin layers of glass and polarizers, making it highly susceptible to damage. When installing and using the LCD module, please ensure that excessive impact is not applied. Cleaning Treatment When cleaning the surface of the LCD panel, use a soft cloth dipped in the following solvents to wipe gently: Isopropyl alcohol Ethanol Do not use dry or hard materials to wipe the panel surface, as this will damage the polarizer on the panel. Especially avoid using the following solvents: Water Ketones Aromatic hydrocarbon solvents Electrostatic Prevention The LCD display module uses CMOS integrated chips for driving. Therefore, it is recommended to connect unused input pins to VDD or VSS. Do not input any signals into the module until the operator’s body is grounded and the power is turned on. All equipment in the work/assembly area must be protected against electrostatic discharge. Storage and Packaging LCD modules are fragile components, and the packaging must protect them from damage due to severe shaking or falling from high places. To prevent accelerated product degradation, avoid exposing the modules to direct sunlight or storing them in high-temperature and high-humidity environments. For long-term storage (e.g., several years), it is recommended to store the module in a polyethylene bag, ensuring absolute sealing and dryness. Store in a dark place, and ensure that the polarizer surface does not come into contact with any other objects. Usage Precautions Operate within the rated voltage range, as excessively high voltage will reduce the module’s lifespan. At low temperatures, the response speed of the LCD will decrease. Due to temperature effects, the display color of the module may vary to some extent at different temperatures. If pressure is applied to the display area, the display effect may be affected. If liquid adheres to the contact pins, chemical corrosion may occur when power is applied, leading to open circuits on the pins. Use within the operating temperature range. Safety If liquid crystal leaks from the panel and comes into contact with your hands, wash it off with soapy water immediately. Be sure to avoid ingestion.

Whether for LCD, TFT, or OLED displays, environmental compliance directly impacts product market access and brand image in sectors like high-end equipment, industrial controls, and consumer electronics. This article clearly explains EASTERN DISPLAY’s approach to RoHS lead control. 1. The Hazard of Lead: A Common Enemy of Environment and Health Lead is a toxic heavy metal. If it leaches from discarded electronic products into the environment, it causes long-term contamination of soil and water sources. Ultimately, it endangers human health through the food chain, particularly affecting children’s nervous system development. Therefore, our company fully recognizes that implementing lead-free practices is not just a regulatory requirement but also a vital aspect of our corporate social responsibility. 2. Presence and Challenges of Lead in Display Modules In traditional LCD and TFT displays, lead may be present in glass substrates, electrode materials, or soldering processes. Even in technologically advanced OLED displays, the encapsulation process might involve lead-containing materials. It is worth noting that the price of OLED displays partly reflects the high requirements of complex processes like lead-free encapsulation. Comprehensive identification and control of these potential risk points form the foundation for achieving full product compliance. 3. Exemption Clauses: A Pragmatic Approach to Ensure Reliability The RoHS Directive is not a “one-size-fits-all" rule. In areas where no reliable alternatives currently exist, such as in certain glass, ceramic, or piezoelectric materials, the Directive establishes “exemption clauses." This demonstrates the scientific and pragmatic nature of the regulation. Industrial & Automotive Electronics: Critical components in TFT displays for vehicle central controls or LCD displays used in harsh industrial environments may qualify for exemptions. This ensures their ultimate reliability under conditions like vibration, high temperatures, and low temperatures. Medical Devices: LCD displays equipped in life-critical medical equipment have paramount stability requirements. Exemption clauses safeguard the safety of such products. Our company accurately understands and applies these exemption clauses, aiming to provide the optimal balance of performance and reliability for our customers’ critical applications. 4. EASTERN DISPLAY’s Commitment and Control System We solemnly commit that all our products comply with RoHS Directive requirements and have established a mature, transparent compliance assurance system: Source Control & Supply Chain Collaboration: We rigorously screen suppliers and require them to provide authoritative RoHS Declarations of Conformity and test reports. This ensures the environmental friendliness of materials used in our LCD, TFT, and OLED display modules from the source. Precise Identification & Transparent Management: For specific lead-containing materials used under exemption clauses, we clearly identify them in technical documentation. This ensures high transparency for our customers and facilitates your product compliance declarations. Customer-Oriented, Dual Assurance: For customers pursuing completely lead-free solutions, we provide LCD display products that fully meet the 1000ppm threshold limit. Simultaneously, if your product falls under exempted applications (e.g., in industrial control, medical devices, automotive electronics), we also provide complete technical support and compliance documentation. Summary From basic LCDs to sophisticated OLED displays, environmental compliance is an irreversible global trend. Choosing EASTERN DISPLAY as your display module partner means you not only get high-quality products but also a reliable solution for navigating global environmental regulations. We are committed to collaborating with our customers to jointly promote the sustainable development of the green electronics industry.
