Get panels and modules chosen for real projects - not just catalog SKUs. Whether you specify tens or thousands of character LCDs, colour TFTs, or compact OLEDs for education kits, signage or product development, Communica combines immediate local stock with procurement-ready support: VAT invoices, branch collection, account quotes and supply planning from our Samrand warehouse.
Why buy wholesale from a local distributor
Local supply shortens lead times and removes import uncertainty. For classroom rollouts or production runs, that means predictable deliveries to Samrand, Pretoria CBD or Cape Town branches, easy returns and faster technical support. We stock leading maker and industrial-friendly brands across our collections for displays, controllers and accessories; see the Shop by Category section for ranges and part families.
- Stock visibility and branch collection reduce project delays.
- Volume quoting and VAT invoicing simplify procurement and tender responses.
- Accessory bundles (cables, controllers, touch overlays) delivered with displays save assembly time.
Common wholesale display types and when to choose them
Match panel type to use-case: character LCDs for low-cost data readouts, monochrome OLEDs for compact wearable interfaces, IPS TFTs for colour-rich UI and outdoor-viewable transflective TFTs for signage. For maker education kits choose modules with simple interfaces (SPI/I2C) and library support; for embedded products prioritise controller compatibility and supply continuity.
| Type | Typical sizes | Why pick it |
|---|---|---|
| Character LCD (HD44780) | 16x2, 20x4 | Low cost, easy wiring, ideal for student projects |
| OLED (monochrome) | 0.66"-2.42" | High contrast, low-power, great for wearables |
| TFT / IPS | 1.3"-10"+ | Full colour, wide viewing angles, touch options available |
Specification callouts - what to check before ordering
Evaluate interface, voltage, brightness, viewing angle and mechanical fixing. For embedded applications confirm controller compatibility (e.g., ILI9341, ST7735) and chosen MCU library support. If you plan outdoor signage, compare typical brightness (cd/m2) and whether a transflective option is appropriate for sunlight readability.
Example wiring diagram for a common SPI TFT (controller: ILI9341):
MCU SPI MOSI ----> MOSI MCU SPI MISO ----> MISO (if used) MCU SPI SCLK ----> SCLK MCU GPIO CS ----> CS MCU GPIO DC ----> DC MCU GPIO RST ---> RST +3.3V -----------> VCC GND ------------> GND
For library-ready setups check that the module includes level shifters for 5V systems or order the variant designed for 3.3V logic to avoid extra hardware.
