FAQ
What is an FSTN LCD Glass Panel?
An FSTN LCD Glass Panel is a custom monochrome LCD glass using Film-compensated Super Twisted Nematic technology. It is designed to improve contrast, background appearance and readability compared with standard STN LCD glass.
Is FSTN LCD glass the same as a complete LCD module?
No. FSTN LCD glass is the glass display element. A complete module may also include polarizers, backlight, driver circuit, PCB, connector, frame and front-panel structure.
What is FSTN LCD glass best used for?
FSTN LCD glass is best used for Graphic LCD, Dot Matrix LCD and higher-readability monochrome display applications that need a cleaner background and stronger contrast than standard STN.
Is FSTN LCD better than STN LCD?
FSTN normally provides better readability and a cleaner display effect than standard STN. Standard STN may still be more cost-effective for general monochrome applications.
Is FSTN LCD suitable for Segment LCD?
Yes. FSTN can be used for Segment LCD projects when improved contrast and readability are required, although TN or HTN may be more economical for simple fixed content.
Is FSTN LCD suitable for Graphic LCD?
Yes. FSTN is widely used for Graphic and Dot Matrix LCD formats such as 128×64, 192×64, 240×64 and 240×128.
What is the difference between FSTN and TN or HTN LCD?
TN and HTN are mainly selected for simpler Segment LCD content. FSTN supports more complex monochrome content and offers better readability for text, icons, menus and pixel-based graphics.
What is the difference between FSTN and VA LCD?
FSTN is selected for readable monochrome text and graphics. VA is mainly selected for a premium high-contrast black-background Segment LCD effect.
Can FSTN LCD glass use positive display mode?
Yes. Positive FSTN LCD normally shows dark or blue content on a light grey or grey-white background.
Can FSTN LCD glass use negative display mode?
Yes. Negative FSTN LCD normally shows light content on a blue, dark-purple or dark background and usually requires a suitable backlight.
What is reflective FSTN LCD?
Reflective FSTN LCD uses ambient light and can operate without continuous backlight, making it suitable for low-power instruments and meters.
What is transmissive FSTN LCD?
Transmissive FSTN LCD relies on backlight for visibility and is used in indoor or low-light products.
What is transflective FSTN LCD?
Transflective FSTN LCD can use ambient light and optional backlight, making it suitable for mixed-lighting environments.
Can FSTN LCD glass use LED backlight?
Yes. Backlight color, brightness, current, light guide and mechanical structure can be reviewed according to the display mode and product design.
What connection methods are available?
FSTN LCD glass can use PIN, zebra, FPC or a project-based module structure depending on the glass size, resolution, customer PCB and assembly method.
What is static or multiplex driving?
Static driving controls each segment directly. Multiplex driving shares COM and SEG electrodes to support more display information with fewer connections. Duty, bias, voltage and contrast must be reviewed together.
Can you replace an existing FSTN LCD glass?
Yes. Please provide the old LCD sample, glass outline, viewing area, segment layout or resolution, pin details, driving information, backlight, photos and product information.
What information is required for quotation?
Please provide glass size, viewing area, segment layout or resolution, display mode, optical mode, backlight, driving method, voltage, connection type, viewing direction, temperature, touch requirement, quantity, schedule and available drawings or samples.
