Your Trusted LCD Partner with 16 Years of Specialized Experience---Tianfu

When you compare multiple suppliers, beyond parameters and prices, we would like to convey our unique value as a small-and-medium-sized manufacturer with over 16 years of dedicated experience in the liquid crystal display industry. Choosing us means you get more than just a display module – you gain a stable, reliable, and highly responsive long-term partner.

✅ We Know Our Products, and More Importantly, We Understand Your Needs

· Proven Manufacturing Processes: 16 years of accumulated experience has given us an in-depth mastery of the application of classic driver ICs such as the HX8238D. From COG bonding and ITO film lamination to aging tests and 100% inspection, we have established mature and stable production workflows, ensuring every module you receive delivers consistent performance, reliability, and durability.

· Pain Point-targeted Design: The module’s multi-interface compatibility (RGB/CCIR) and industrial-grade wide-temperature tolerance are the results of design optimizations based on extensive customer feedback. We understand that small and medium-batch customers need a "versatile" and robust display to meet the diverse requirements of multiple projects.

✅ Our Moderate Scale Means Greater Focus and Flexibility

· Rapid Response & Communication: No cumbersome procedures typical of large enterprises. Your technical inquiries, specification confirmations, or modification requests will be directly handled by experienced engineers or project managers, with response times measured in hours rather than days.

· Flexible Customization Support: Whether you need adjustments to FPC length, interface pinout, backlight brightness, or small-batch adaptation of specific firmware initialization codes, we have the capability for rapid engineering responses. Your order of 500 units is treated with the same priority as key accounts.

· Focus-driven Value: We specialize in the manufacturing of small-to-medium sized TFT and touch screens, with all process improvements and quality control measures centered on this core business. What you get is the output of a team dedicated to a focused field of expertise.

✅ We Value Our Reputation, Ensuring Controlled Quality and Stable Supply

· Full-cycle In-house Management: From material procurement and SMT placement to module assembly and testing, all critical processes are completed in our own facilities. This ensures full quality traceability and control, eliminating the risks of quality fluctuations caused by outsourcing.

· Long-term Supply Commitment: We fully recognize the importance of product lifecycle for your projects. For classic components such as the HX8238D, we have established a secure inventory system and can provide guaranteed continuous supply, supporting your long-term production needs with zero worries.

faq

Q1: Does this screen support touch functionality?

Yes, this module integrates a resistive touch screen (ITO film) that supports single-point touch. It features a standard 4-wire resistive interface and requires an external touch control chip or an MCU with a built-in ADC.

Q2: Can you provide a version with capacitive touch?

The current standard version comes with resistive touch. For capacitive touch (supporting multi-point touch), please contact us for customization.

Q3: What is the difference between CCIR656 and CCIR601 in the interface? How should I choose?

CCIR656 is an embedded sync signal format (commonly used for digital video streams), while CCIR601 is a separate sync signal format. If your processor outputs standard ITU-R BT.656/BT.601 video signals (e.g., certain multimedia processors), direct connection is feasible. If you are unsure, please provide your main control model and we will assist with the selection.

Q4: Can the operating temperature range of -10°C ~ +60°C be extended to a wider range?

The standard product has this temperature range. For industrial wide-temperature requirements such as -30°C ~ +80°C, customization can be discussed, which usually involves adjustments to liquid crystal materials and manufacturing processes.

Q5: Are matching driver boards or adapter boards available?

We can provide RGB adapter boards and touch adapter boards (including touch ICs) to simplify your circuit design. Please consult our sales team for details.

Production & Usage Related

Q6: What is the ESD protection level of the module?

The module has passed ESD tests of ±8kV (air discharge) / ±4kV (contact discharge), meeting the requirements of general industrial environments. It is recommended to take appropriate grounding and insulation measures when designing the product housing.

Q7: Will a response time of 15ms cause motion blur?

15ms is the typical gray-to-gray response time, which is sufficient for most scenarios such as industrial control, instrumentation, and interactive interfaces. For high-speed video playback (e.g., above 30fps), it is recommended to evaluate the actual dynamic image performance.

Q8: How is the backlight of the module connected?

The module itself does not include a backlight driver circuit, but provides LED backlight pins (usually +3.3V and GND). You need to connect an external constant current source or backlight driver circuit. The current depends on the series-parallel configuration of the backlight LEDs (typical value: approx. 60-100mA).
