FAQs

People Also Ask

Contact Us
Which industries are your products mainly used in?

The main application directions include industrial HMI, automation equipment, medical devices, two-wheeler displays, EV charging terminals, and other embedded systems. These projects usually require stable supply, reliable display performance, and flexible customization rather than consumer-electronics styling.

What can be customized for a TFT LCD display project?

Customization can include display size, resolution, interface, brightness, viewing angle, mechanical outline, wide-temperature adaptation, and display with touch integration. For industrial projects, the most important part is often not the screen alone, but how the module matches the real operating environment and product structure.

Can AG, AR, or AF treatment be supported?

Yes. AG, AR, and AF options can be considered for capacitive touch screen and cover glass projects according to the usage environment. These treatments are typically selected based on glare control, reflection management, fingerprint resistance, and front-surface usability requirements. They are applied on the touch or cover glass side, not described as a TFT panel feature by itself.

Are your displays suitable for sunlight-readable applications?

High-brightness display solutions are available for applications that need better visibility under strong ambient light. In real use, sunlight readability depends on more than the backlight alone. The cover lens, bonding method, and module structure also play an important role in outdoor visual performance.

How can I start a custom project inquiry?

It is helpful to share the key project information at the beginning, such as screen size, resolution, interface, brightness target, touch requirement, operating environment, mounting structure, and estimated quantity. The clearer the project input is, the easier it is to recommend a more suitable display and touch solution.
