FAQ
What is a Monochrome LCD Display?
A Monochrome LCD Display is an LCD module that shows information in one main display color or contrast mode. It is used for text, numbers, icons, symbols, menus, status messages and simple graphics.
What types of Monochrome LCD Displays do you support?
DisplayMan supports Character LCD, Graphic LCD, Segment LCD, Dot Matrix LCD, COB LCD and COG LCD display modules.
How should I start selecting a Monochrome LCD?
Start from display content. First decide whether the product needs fixed text rows, fixed custom segments or pixel-based monochrome content. Then choose the module structure, LCD technology, display mode, backlight, connection and mechanics.
What is the difference between Character LCD and Graphic LCD?
Character LCD uses fixed character cells such as 16×2 or 20×4. Graphic LCD uses a pixel matrix and can display icons, menus, diagrams and flexible monochrome layouts.
What is the difference between Segment LCD and Dot Matrix LCD?
Segment LCD uses fixed custom digits and icons built into the LCD glass. Dot Matrix LCD uses software-controlled pixels, so its text, icons and simple graphics can change.
What is the difference between COB LCD and COG LCD?
COB LCD has the driver IC bonded on the PCB. COG LCD has the driver IC bonded directly on the LCD glass. COB normally provides more PCB-level integration flexibility, while COG is usually thinner and more compact.
Can Character, Graphic or Segment LCD also be COB or COG?
Yes. Character, Graphic, Segment and Dot Matrix describe display content, while COB and COG describe module structure. These classifications can overlap.
What LCD technologies are available?
Monochrome LCD projects can use TN, HTN, STN, FSTN or VA technology depending on contrast, viewing angle, multiplex ratio, display effect, operating temperature and cost.
What display modes are available?
Positive or negative display modes and reflective, transmissive or transflective optical modes can be reviewed.
Can Monochrome LCD use LED backlight?
Yes. White, blue, green, yellow-green, orange or another project-based backlight color can be reviewed according to the LCD mode and product design.
Can Monochrome LCD include touch buttons?
Yes. Capacitive touch-button integration can be reviewed for selected COB or custom monochrome LCD module projects.
What connection structures are available?
PIN, zebra, FPC, PCB connector and project-based cable structures can be reviewed according to the LCD glass, module structure and customer PCB.
Can Monochrome LCD be used in low-power products?
Yes. Reflective Segment LCD and selected monochrome LCD designs are widely used in meters, portable devices and battery-powered products.
Does custom Monochrome LCD require tooling?
Standard Character and Graphic LCD modules may not require tooling. Custom Segment LCD glass, special outlines, special icons or custom COB and COG structures normally require tooling, MOQ and engineering review.
Can you replace an existing Monochrome LCD?
Yes. Please provide the old LCD model, photos, drawing, glass size, pin definition, connector, interface, backlight, driver information and sample if available.
When should I choose TFT LCD instead?
Choose TFT LCD when the product needs full-color graphics, images, video, animation, modern graphical UI or a touch-screen interface.
When should I choose OLED instead?
Choose OLED when self-emissive contrast, thin structure or OLED visual effect is essential. For low-power fixed content, reflective readability or cost-sensitive products, Monochrome LCD may be more practical.
What information is required for quotation?
Please provide display content, LCD category if known, glass size, viewing area, segment layout or resolution, display mode, LCD technology, backlight, module structure, connection, interface, viewing direction, temperature, quantity, schedule and available drawings or samples.
