FAQ
What is a Graphic LCD Display?
A Graphic LCD Display is a monochrome LCD module with a pixel matrix, used to display icons, symbols, menus, curves, diagrams, simple graphics and flexible text layouts.
What are common Graphic 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 Graphic LCD?
Choose a Graphic LCD when the product needs flexible monochrome content such as icons, diagrams, curves, custom fonts or free-position text.
What is the difference between Graphic LCD and Character LCD?
Character LCD uses fixed character cells such as 16×2 or 20×4. Graphic LCD uses a pixel matrix and can display custom icons, graphics and flexible layouts.
What is the difference between Graphic LCD and Segment LCD?
Graphic LCD uses a pixel matrix for flexible content. Segment LCD uses fixed custom digits, icons and symbols designed for one specific interface.
What is the difference between Graphic LCD and TFT LCD?
Graphic LCD is normally monochrome and intended for simple graphics and text. TFT LCD supports full-color graphics, images, animation and video.
Can Graphic LCD use COB structure?
Yes. COB Graphic LCD modules use a PCB with the driver IC bonded on the board and are practical when PCB-level integration, connectors or a stronger module structure are required.
Can Graphic LCD use COG structure?
Yes. COG Graphic LCD modules bond the driver IC directly onto the glass and are useful when a thinner, more compact module with FPC connection is required.
What LCD technologies are available?
Graphic 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 you customize the backlight color?
Yes. White, green, blue, yellow-green, orange or another project-based backlight color can be reviewed according to the selected module and quantity.
What interfaces are available?
The interface depends on the controller IC and module design. Parallel, serial, SPI, I2C or another project-based interface can be reviewed.
Can the FPC or connector be customized?
Yes. FPC length, direction, connector type, pin definition and cable orientation can be reviewed according to the product structure.
Can you provide wide-temperature Graphic 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 Graphic LCD display animation?
Simple frame changes or basic movement may be possible depending on the resolution, controller and refresh rate, but Graphic LCD is not intended for smooth full-color animation or video.
Can you replace an existing Graphic LCD?
Yes. Please provide the old module model, datasheet, photos, pin definition, interface, connector or FPC, module outline, backlight information and sample if available.
What is the main limitation of Graphic LCD?
Graphic LCD provides flexible monochrome content but has lower visual richness and refresh capability than TFT LCD, and usually requires more UI control than Character LCD.
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.
