A 1.3 inch TFT LCD Display is an ultra-compact, high-density active-matrix liquid crystal display (AMLCD) engineered in a unique circular/round form factor. It delivers a sharp 240 x 240 RGB pixel resolution utilizing Thin-Film Transistor (TFT) technology for independent, high-speed pixel control.
What It Is: A premium micro-display module featuring full-viewing-angle IPS technology that ensures crisp, true-color visual performance with no grayscale inversion or color shifting from any angle.
Core Structure: The module is composed of a specialized circular IPS liquid crystal panel, an integrated high-performance driver IC (such as the GC9A01), a flexible printed circuit (FPC) with electromagnetic interference (EMI) shielding, and an optimized LED backlight unit (ranging from 300 to 500 cd/m²).
What It Is Used For: It serves as an advanced human-machine interface (HMI) for space-constrained, modern hardware designs. It bridges the gap between hardware functionality and fluid GUI interaction, allowing developers to render complex animations, circular dials, progress bars, and rich text variables seamlessly.
To support diverse embedded engineering requirements, Hotdisplay manufactures three primary hardware configurations for our 1.3-inch round display series:
Raw TFT Display Panels (No Driver Board): Model TFT-H013A6QQIGC5N10 features a 10-pin FPC soft cable interface. This ultra-thin (1.6mm profile) panel connects directly to a customer’s mainboard via standard SPI serial protocols, making it ideal for high-volume, cost-sensitive, and space-restricted electronics.
Smart UART Serial Port Modules (Zero-Code EzUI Series): Model HTM-H013A6-UART-A02 comes integrated with an onboard EzUI control driver board. Communicating over a simple 4-pin UART/RS232 interface, it supports code-free GUI development using the EzUITool software, bypassing low-level microcontroller programming entirely.
All-in-One IoT Development Modules (Knob Display Kits): Model ESP32-C3-DEMO-SPI03 combines the 1.3-inch circular display with a powerful RISC-V 32-bit single-core processor development board. Featuring integrated 2.4GHz Wi-Fi, Bluetooth BLE 5.0, and an onboard EC35 hollow rotary encoder, it functions as an intelligent, press-switch rotary knob module.
Fluid Round Aesthetics: True circular layout eliminates black dead zones at corners, natively fitting round industrial bezels and modern device profiles.
Sunlight-Readable Performance: Offers a powerful backlight configuration up to 500 cd/m² (nits), ensuring critical tracking metrics remain clearly visible outdoors or under bright overhead lighting.
Advanced Ruggedization: Built-in industrial-grade 8KV anti-static (ESD) circuit protection ensures high reliability and survival rates upon physical contact in dry operating environments.
Cross-Platform Firmware Compatibility: Engineered for immediate prototyping across premium developer ecosystems, offering seamless compatibility with C8051, STM32, Arduino, Raspberry Pi, and the LVGL graphics library.
Robust Thermal Performance: Operates reliably across a standard industrial ambient temperature spectrum of -20°C to +70°C.
Strict Environmental Compliance: Fully RoHS compliant, meeting international safety and environmental standards for global commercial export.
IPS Circular Screen Panel: Provides a 1,000:1 contrast ratio with true 80/80/80/80 degree full viewing angles and deep black levels when pixels are turned off.
GC9A01 Controller IC: The industry-standard micro-display driver that optimizes frame refresh rates and optimizes power management under a low 3.3V supply voltage.
EMI-Shielded FPC Soft Cable: Available in unique lengths (such as an extended 47.5mm line) featuring integrated electromagnetic interference shielding to preserve signal integrity.
Integrated Onboard Encoder (Demo Kits): An EC35 hollow encoder providing precise mechanical detents and physical press-switch feedback for tactical menu selection.
Wireless Main Controller (Demo Kits): A high-speed 160MHz ESP32-C3 processing core supporting stable IoT wireless bridging and real-time cloud data rendering.
Hotdisplay provides full OEM/ODM hardware customization to resolve strict physical and structural design bottlenecks:
FPC Cable Modifications: Tailoring of the flexible printed circuit length (e.g., swapping between standard and long-cable versions like the TFT-H013A6QQIGC7N10) and pinout configuration.
Interface Overhaul: Swapping from a resource-saving 4-wire SPI interface over to a high-bandwidth 16-pin MIPI interface (TFT-H013A1HQIST3N16) for ultra-smooth video playback.
Touch Screen Lamination: Integration of premium custom-engineered projected capacitive touch panels (CTP) supporting wet-finger or gloved input variables.
Optical Optimization: Upgrading or downscaling backlight arrays to perfectly hit target power-consumption budgets versus high-nit visibility goals.
When submitting an RFQ or confirming an order with Hotdisplay, procurement teams must verify these technical parameters to ensure absolute compatibility:
Driver Board Dependency: Determine if your engineering team requires a raw 10-pin SPI panel to integrate into an existing PCB layout, or a plug-and-play UART module to accelerate production schedules without coding low-level display drivers.
Cable Clearance and Length: Review your internal enclosure routing and specify whether your assembly requires the standard 47.5mm extended cable variant or a shortened version to avoid pinching in tight watch housings.
Interface Resource Budgeting: Verify if your host microcontroller supports a 4-wire SPI connection, a 16-pin MIPI DSI interface, or a basic 4-pin UART serial interface.
Haptic & Interactive Feedback Needs: Determine if your display interface is purely output-only, requires a capacitive touch surface, or requires an integrated mechanical rotary encoder knob setup for physical rotational control.
