Buy Displays in South Africa - LCD, OLED & Touch Panels for Makers

Why choose Communica for displays

Find the right display quickly without long import delays: Communica stocks a broad range of LCD, OLED, TFT and touchscreen modules from hobby-grade to embedded-ready, with local collection and VAT invoices for institutional purchasing. Our advantage is practical availability - pick up from Samrand, Pretoria CBD or Cape Town - and clear compatibility guidance so your prototype moves from breadboard to enclosure without surprise redesigns.

Common display types and where to use them

Choosing the right display starts with application: small character LCDs for instrumentation, IPS TFTs for operator interfaces, OLEDs for low-power wearable prototypes, and capacitive touch panels for kiosk projects. Below is a quick comparison to orient your decision.

Key specification callouts (what to check)

• Interface: SPI, I2C, parallel RGB, HDMI - match to your MCU or SBC.
• Resolution & pixel density: determines clarity for text and UI elements.
• Backlight & brightness (cd/m2): needed for daylight visibility.
• Viewing angle & colour type: IPS recommended for accurate colours and wide angles.
• Power requirements: voltage, current draw, and sleep modes for battery projects.
• Touch type & controller: ensure driver support for your OS or microcontroller.

If you are prototyping on Raspberry Pi or Arduino, check our touch-ready TFTs and HDMI-capable panels in Collections to find modules that plug into common boards. Explore product families on our Shop by Category page for quick browsing.

Compatibility notes and quick wiring diagram

Match the interface and logic level first. Many microcontroller-friendly displays use 3.3V logic; use level shifters if your host runs at 5V.

For Raspberry Pi HDMI panels, plug-and-play is typical, but confirm kernel driver support for touch controllers. We list driver notes on many product pages in All Products so you can verify before purchase: See All Products.

Selection guidance, accessory bundles and local logistics

Select by use-case rather than specs alone. For visible UIs choose IPS TFTs with >300 cd/m2; for battery meters prefer OLEDs with sub-1 mA sleep states. We curate accessory bundles (adapter boards, level shifters, ribbon cables and protective bezels) to remove integration friction - check the Shop by Brand area for compatible modules and accessories.

Specification examples and power calculation

Use Ohm’s law and simple power math to estimate supply needs for backlights and controllers:

I = P / V (current required), where P is power in watts and V is supply voltage. For a 5V backlight consuming 0.6W: I = 0.6 / 5 = 0.12A. Add controller current (typ. 30-200mA for small TFTs) to size a regulator.

Troubleshooting and practical tips

• No image on SPI TFT: confirm CS/DC wiring and that MOSI/SCLK are on hardware SPI pins for best reliability.
• Touch not responding: verify I2C address and pull-ups; many controllers use 3.3V logic.
• Faint backlight: check series resistor or PWM backlight control settings.

For students and tertiary projects, we provide bulk pick-up and quoting - request an account quote or VAT invoice for departmental purchases. Branch collection details and trading hours are available on our Branches & Trading Hours page to plan same-day pickup where stock permits: Branch info. If you need help comparing modules, use Compare Specs or Request a Quote to get component-level advice and compatibility checks from our technical sales team.
