TSD 1080x1080 resolution 8.2 inch round TFT LCD with MIPI interface

Description:

TSD TFT item number TST082FHBF-E40A is an 8.2-inch circular color TFT-LCD module from Team Source Display (TSD). Built on amorphous silicon (a-Si) active-matrix technology with a 1080 × 1080 square-pixel resolution, it delivers a perfectly round 208.01 mm (Ø8.2") active display area in an ultra-slim 4.0 mm thickness — an ideal human-machine interface (HMI) display for modern, design-driven products.

Unlike conventional rectangular panels, the circular format eliminates wasted corners and creates a natural focal point, making this module the display of choice for products where aesthetics and intuitive interaction are equally important. The panel features a normally-black IPS-type cell with RGB vertical stripe arrangement, supporting 16.7M colors, a 1200:1 typical contrast ratio, and full viewing angles (80° min. / 85° typ., CR≥10) — ensuring consistent image quality from any viewing position around the dial.

• Features:
•  

• 1. Circular 1080 × 1080 Format for Modern UI Design

  The 1:1 square resolution mapped to a round active area simplifies UI development — designers can render dial graphics, gauges, and radial menus with symmetric pixel mapping and no rectangular-to-circular cropping overhead. The thin border design (2.5–5.45 mm) maximizes screen-to-body ratio, allowing device makers to create sleek, bezel-minimal front panels.

  2. MIPI-DSI High-Speed Interface

  The module uses a 4-lane MIPI-DSI interface (79 MHz pixel clock, 60 Hz refresh), natively compatible with mainstream mobile and embedded SoCs such as Qualcomm, MediaTek, Rockchip RK series, and STM32MP1-class processors. MIPI's low pin count and low EMI simplify PCB routing in compact, round-form-factor devices.

  3. Integrated Touch Architecture (TDDI-Ready)

  The 40-pin connector includes dedicated capacitive touch controller pins (TP-SCL, TP-INT, TP-RST), and the power sequence diagram includes a TP gesture mode — enabling low-power wake-on-touch and always-on glanceable displays. This makes the module ready for smart dial and wearable-style interaction.

  4. Carefully Engineered Backlight

  56 KSF white LEDs in a 7-series × 8-parallel array deliver 500 cd/m² luminance with 80% (min.) 9-point uniformity, driven by a standard 21 V boost converter. With 30,000-hour LED lifetime, the module supports years of continuous duty in always-on applications.

  5. Defined Power Sequencing & Reliability

  A fully specified power-on/off sequence (T1–T15 timing) protects the TFT cell and driver IC, and the module passes a stringent reliability suite: HTS/LTS (±80 °C / −30 °C, 240 hrs), thermal cycling (−30 ~ +80 °C, 100 cycles), 60 °C/90% RH humidity tests, image-sticking resistance, and ESD Class B — verified on the FT8201P platform.

• Applications: 
•  

• Robotics & AI Companion Devices

  The specification explicitly targets robot applications — the round display serves as an expressive "face" or emotion-driven HMI on service robots, delivery robots, and companion robots, where circular eyes, expressions, and status indicators create natural human-robot interaction.

   

  Smart Home Control Panels & Smart Speakers

  A round touch display is the centerpiece of wall-mounted smart home hubs — controlling lighting, HVAC, security, and scenes with radial menus and dial-style widgets. The MIPI interface pairs directly with common smart-hub SoCs.

   

  Automotive & Motorcycle Instrument Clusters

  1080 × 1080 round LCDs are widely used for digital dashboards, speedometers, and multi-gauge clusters — especially for EVs, motorcycles, scooters, and marine dashboards — thanks to the 500 cd/m² brightness and wide viewing angles.

   

  Smart Watch-Style & Wearable-Form Products

  Ideal for large-format smart display devices: fitness equipment consoles, smart gym mirrors, hotel/room control terminals, and luxury clock-style information displays.

   

  Industrial Dial Gauges & Test Instruments

  Precision round indicators, pressure/temperature gauges, and measurement instruments benefit from the perfectly symmetric active area and high contrast (1200:1) for crisp needle and numeric rendering.

   

  Medical & Beauty Devices

  Skin analyzers, aesthetic treatment devices, and health monitoring kiosks use the round display for friendly, non-clinical UI presentation with touch interaction.

   

  Advertising & Retail Display

  Circular digital signage, product display pedestals, and brand-experience installations leverage the unique form factor for eye-catching, premium visual merchandising.
