4.3 Inch TFT LCD Display Selection
4.3-inch TFT LCD modules are widely used in compact HMI, instruments, medical equipment, appliance controls and embedded terminals. Match the resolution, interface, outline, brightness, touch stack and controller to the host system before choosing a model.
Common 4.3-Inch Configurations
| Configuration | Typical resolution | Interface | Typical fit |
|---|---|---|---|
| Standard landscape TFT | 480×272 | RGB/TTL, 40-pin or model-specific | Embedded HMI, appliance controls and instruments |
| High-resolution / portrait option | 800×480 or model-specific | MIPI DSI, RGB or LVDS depending on model | Compact terminals requiring finer UI detail |
| Touch display module | 480×272 or 800×480 | LCD interface plus PCAP I²C/USB or resistive touch | Operator panels and interactive controls |
| Controller kit | Panel-native timing | HDMI input converted to RGB/LVDS/MIPI | Raspberry Pi, PC and simulator integration |
These are common starting points, not universal specifications. Confirm active area, outer dimensions, connector, pin definition, timing, brightness and temperature from the exact model datasheet.

Raw TFT Module or HDMI Display Kit?
A raw 4.3-inch TFT is appropriate when the embedded processor supports the panel’s native RGB, MIPI or LVDS timing. An HDMI controller kit is easier for a PC or Raspberry Pi but adds board size, power, cables and firmware considerations. The controller must match the exact panel pinout and backlight.
For replacement projects, provide the current panel model, datasheet, outline drawing and host connector. Similar diagonal size does not mean drop-in compatibility. Even two 480×272 panels can use different pinouts, timings, FPC positions or backlight circuits.

Frequently Asked Questions
Is 480×272 the standard resolution for every 4.3-inch TFT?
No. It is common, but 800×480 and other formats also exist. Always verify the exact model and active area.
Can a 4.3-inch TFT connect directly to HDMI?
Raw TFT modules usually cannot. A compatible controller board must convert HDMI to the panel interface and supply the correct timing and backlight power.
Can PCAP or resistive touch be added?
Yes for suitable projects. Confirm the touch outline, controller interface, cover glass, bonding method, quantity and environmental requirements.
Can one 4.3-inch panel replace another with the same resolution?
Not automatically. Compare outline, active area, pinout, timing, voltage, connector position and backlight circuit.
What should be included in an RFQ?
Provide size, resolution, interface, outline drawing, brightness, temperature, touch need, host system, sample quantity and annual quantity.
