Value beyond the sticker price
A cheap display can still be a dependable part of your project if you pick the right specs. Focus on interface (I2C, SPI, parallel), backlight/power needs, resolution and viewing angle. For classroom kits and student projects we recommend modules with I2C backpack options and onboard level shifting to avoid additional components.

Quick spec compass - pick the right display
Use this simple decision flow: if you need text only, choose a 16x2 or 20x4 character LCD with I2C; for graphics but limited pins, pick SPI OLED/TFT; for better colour and viewing angle, choose IPS TFT. Consider sunlight readability and backlight current for battery-powered builds.
| Type | Typical size | Interface | Good for |
|---|---|---|---|
| Character LCD | 16x2, 20x4 | Parallel / I2C backpack | Text readouts, simple menus |
| Monochrome OLED | 0.66"-1.5" | I2C / SPI | Low-power icons, small UI |
| Colour TFT | 1.8"-3.5" | SPI / MCU parallel | Graphics, images, touch options |
| IPS panels | 2.8"-4.3" | SPI / parallel | Wide viewing angles, demos |
Specification callouts to watch
Key specs to check on the product page: supply voltage (3.3V vs 5V), logic level needs, current draw with backlight on, required library support (Arduino/PlatformIO), and whether a touch panel is resistive or capacitive. If you need invoicing for projects or procurement, Communica supports VAT invoices and account quotes for education and teams.
