FAQ
What is a Dot Matrix LCD Display?
A Dot Matrix LCD Display is a monochrome LCD module that uses rows and columns of pixels to display text, icons, symbols, menus and simple graphics.
Is Dot Matrix LCD the same as Graphic LCD?
The two terms are very close in practical use. A Graphic LCD is usually a dot matrix LCD module used for pixel-based graphics, icons and flexible text layouts.
Why does DisplayMan separate Dot Matrix LCD and Graphic LCD pages?
DisplayMan uses Graphic LCD Displays for standard pixel-based graphic LCD modules and Dot Matrix LCD Displays for broader monochrome pixel-matrix projects and dot-based display structures.
What are common Dot Matrix LCD resolutions?
Common reference resolutions include 128×32, 128×64, 160×160, 192×64, 240×64, 240×128 and 320×240.
When should I choose a Dot Matrix LCD?
Choose a Dot Matrix LCD when the product needs software-controlled monochrome text, icons, menus or simple graphics but does not require full-color TFT content.
What is the difference between Dot Matrix LCD and Character LCD?
Character LCD uses fixed character positions such as 16×2 or 20×4. Dot Matrix LCD uses individually controlled pixels, allowing custom fonts, icons and flexible layouts.
What is the difference between Dot Matrix LCD and Segment LCD?
Segment LCD has fixed digits and icons built into the glass. Dot Matrix LCD content can change by software through pixel control.
What is the difference between Dot Matrix LCD and TFT LCD?
Dot Matrix LCD is normally monochrome and intended for text, icons and simple graphics. TFT LCD supports full-color images, animation, video and modern graphical UI.
Can Dot Matrix LCD use COB structure?
Yes. COB Dot Matrix LCD modules use a PCB with the driver IC bonded on the board and are practical for stronger module assemblies and PCB-level integration.
Can Dot Matrix LCD use COG structure?
Yes. COG Dot Matrix LCD modules bond the driver IC directly onto the glass and are useful for thinner, compact modules with FPC connection.
What LCD technologies are available?
Dot Matrix LCD projects commonly use STN or FSTN, while TN or another monochrome LCD direction may be reviewed for selected requirements.
What display modes are available?
Positive or negative display modes and reflective, transmissive or transflective optical modes can be reviewed.
Can the backlight color be customized?
Yes. White, green, blue, yellow-green, orange or another project-based backlight color can be reviewed according to the module and quantity.
What connection structures are available?
COB, COG, FPC, PIN, zebra and project-based connector structures can be reviewed according to the module and product design.
Can Dot Matrix LCD display animation?
Simple frame changes or basic movement may be possible depending on the controller and refresh rate, but Dot Matrix LCD is not intended for smooth full-color animation or video.
Can you provide wide-temperature Dot Matrix LCD modules?
Selected modules and custom projects can be reviewed for wider operating temperature. The exact range must be confirmed from the selected module specification.
Can you replace an existing Dot Matrix LCD?
Yes. Please provide the original model, datasheet, photos, pin definition, interface, connector or FPC, active area, backlight information and sample if available.
What information is required for quotation?
Please provide resolution, module size, active area, display mode, backlight color, COB or COG preference, interface, connector or FPC, viewing direction, temperature, quantity, schedule and available drawing or sample.
