Q1: Is it possible to purchase samples of Tianma TM070RDHG23-40?
A: Of course. We strongly recommend that every customer test before bulk purchase. There is no MOQ for regular models. However, Tianma TM070RDHG23-40 is currently discontinued, and we only have stock available. Please contact our sales manager to confirm product availability when placing an order.
Q2: The specifications say "without LED driver," what does that mean? Do I need to purchase a separate LED driver board?
A: Yes. Most industrial TFT LCD displays actually have their own LED backlight driver board. However, Tianma TM070RDHG23-40 is special, and you will need to purchase a separate LED backlight driver board. If you have this need, you can also contact our sales manager; we provide LED backlight driver boards and adapter boards compatible with various models.
Q3: Is brightness customization supported?
A: Of course. We offer customized LCD panel services. However, customized products usually have minimum order quantity requirements; please contact our sales manager for the latest information. You can also purchase brightness adjustment control boards. Please contact us if needed.
Q4: TM070RDHG23-40 itself does not have a touch screen; can a touch screen be provided?
A: Of course. We provide capacitive touch screens, resistive touch screens, and infrared touch screens. We also offer touch screen bonding and glass bonding services. Please contact us if interested.
Q5: How are the products packaged? What are the shipping ways?
A: Generally, we first wrap the LCD panel with an anti-static protective film, then add anti-static foam inside the box. After our packaging, the courier company will further pack it. You can also choose to use a wooden crate. Our shipping ways are usually international logistics such as DHL and FedEx. Products are usually shipped within 7 working days.
