MX-I70FM31-ILX40-F1685

7 inch display with touch screen MX-I70FM31-ILX40-F1685 combines 7 inch IPS LCD, PCAP touch panel and OCA bonding in a compact display solution for embedded equipment. This 7 inch MIPI LCD display delivers 250-nit brightness through 31-pin MIPI interface, while GT911 touch controller supports responsive capacitive touch operation through 6-pin I²C connection. OCA structure creates direct optical bonding between LCD and touch panel, reducing internal reflections and providing cleaner visual integration than conventional air bonding. Custom transparent window on cover glass can be produced according to customer housing, sensor or indicator-light requirements. With overall dimensions of 119.78x180.00x4.66 mm and active area of 94.20x150.72 mm, this 7 inch touch screen display can be integrated as a custom LCD display module for smart control panels, embedded terminals and compact HMI equipment requiring MIPI LCD, capacitive touch and customized cover glass design.

FAQs

People Also Ask

Contact Us
Can you provide LCD and touch screen together?

Yes. We can provide TFT LCD modules with matching capacitive touch screens, including custom cover glass, touch interface, bonding, and display module integration.

What information is needed for a custom touch screen project?

Usually we need the LCD drawing, cover glass drawing, active area, viewing area, interface requirement, operating environment, and application details.

When should I choose OCA bonding?

OCA bonding is suitable for flat TFT LCD modules, standard cover glass structures, and projects that require stable bonding quality, efficient processing, and consistent optical performance. It is often recommended for indoor industrial devices, smart control panels, and regular HMI display modules.

When should I choose OCR / LOCA bonding?

OCR / LOCA bonding is recommended when the display requires stronger gap filling, better durability, or improved outdoor readability. It is suitable for high-brightness LCD displays, outdoor equipment, vehicle displays, medical devices, and applications exposed to stronger light or harsher environments.

Which bonding method is better for outdoor LCD displays?

For outdoor LCD displays, OCR / LOCA bonding is often preferred because it offers strong adhesion, high optical clarity, and good gap-filling performance. When combined with high brightness, wide temperature design, and suitable cover glass, it can help improve sunlight readability and display durability.
