FAQ

What is the difference between a character LCD display and a graphic LCD display?

A character LCD display is designed to show text and symbols using a built-in font table. Each character position is a pre-defined cell (typically 5×8 dots), and the display controller handles character rendering automatically--you simply send ASCII codes. A graphic LCD display, by contrast, controls every individual pixel on the screen. This allows for images and custom graphics but requires significantly more software development.

Is a character LCD display suitable for industrial equipment?

Yes. A character LCD display is particularly suitable for industrial equipment that needs reliable presentation of values, operating states, menus, alarms and error codes without requiring full-color graphics.

Can the backlight color be customized?

Yes. The character LCD modules can be supplied with different LED backlight colors, including white, yellow-green, blue and amber, depending on the LCD mode and product design.

Can Jingda customize a character LCD module?

Yes. Customized solutions can include LCD dimensions, character format, viewing area, polarizer, viewing direction, PCB, connector, controller IC, backlight and electrical interface according to project requirements.
