2.1-inch Circular TFT LCD 480×480 RGB SPI

Model: PL021WQI-B40TPThe 2.1-inch Circular TFT-LCD Display delivers clean, compact visuals with a 480(RGB)×480 resolution and 262K colors (18-bit)—ideal for round UI layouts where space efficiency and clarity matter. With a 3SPI 18-bit RGB interface and a 60 Hz frame rate configuration, this module supports stable display performance for embedded systems. Its normally black, transmissive display mode and 80° (U/D/L/R) viewing angle help maintain consistent readability from different directions.The panel features a 53.28×53.28 mm active area within a 56.18×59.71×2.3 mm outline, and uses the ST7701S driver IC with a 0.5 mm pitch 40-pin connection. It is rated for -20 to 70°C operating and -30 to 80°C storage environments, supporting reliable integration in demanding applications.  Application Embedded HMI | Smart Terminals | Industrial Control | Compact Medical Interfaces Customized Options FPC  | Touch Panel | Cover Glass | Controller Board | Brightness Power & Interface Bring-up for PL021WQI-B40TP PL021WQI-B40TP is built for straightforward integration on embedded carrier boards with a clean, single-rail power design. The panel operates from VDD 2.5–4.8 V (typ. 2.8 V), and its digital inputs follow standard logic thresholds (VIH ≥ 0.8×VDD, VIL ≤ 0.2×VDD) for stable signal compatibility during system bring-up. Typical panel supply current is specified with IDD ≤ 50 mA (VDD=2.8 V, Ta=25°C), making power budgeting simple for compact devices. On the signal side, the module combines 18-bit RGB for pixel data with 3-wire SPI for command/configuration control, enabling flexible MCU/FPGA designs that separate high-speed display data from register initialization. For backlight design, it specifies VF 3.2 V (typ.) with IF 80 mA (typ.) / 88 mA (max.), and uses 4 LEDs in parallel—supporting predictable LED driver selection and brightness control. The module connects via a 0.5 mm pitch 40-pin interface and also exposes practical touch control lines (TP_SCL/TP_SDA/TP_INT/TP_RESET/TP_VCI) for external CTP integration where required. Gesight also provides a range of evaluation accessories to speed up prototyping and bring-up, including an HDMI controller board for quick plug-and-play testing, a mini video board for compact integration demos, and USB connectivity for phone-based display playback, making it easy to validate image output and overall system compatibility.
