Description
Wide Temperature Round TFT Display Product Overview
The TFT-H013A08ZNIST2C16 is a 1.3-inch circular Wide Temperature TFT LCD display module designed and manufactured by HOTHMI. This module integrates a native 360(H) x 360(V) pixel resolution within its genuine circular geometry. It employs an advanced Normally Black LCD mode, ensuring high contrast ratio, accurate color reproduction, and full viewing angle optical performance. Users can observe the screen from various extreme angles with minimal color distortion or grayscale inversion. Additionally, it supports 70% NTSC color saturation, delivering vivid and true-to-life visual colors.
The module integrates touch functionality, with the TFT driver chip using the ST77916 and supporting the MIPI-1 Lane interface, while the capacitive touchscreen driver chip is the CST816T using the IIC interface. In terms of electrical and optical characteristics, the LCD module offers a brightness of 250±50 cd/m², with backlight driving conditions of Vf=3.0±0.3V and If=40 mA, operating voltage VDD/VCI of 3.0±0.3V, and IOVCC ranging from 1.7 to 3.3V.
As a standout feature of industrial-grade hardware, this module is specially reinforced in its engineering architecture and belongs to a standard Wide Temperature product ecosystem. While ordinary consumer-grade displays tend to suffer from slow response, image retention, or black-screen failures under extreme thermal stress, this module operates stably across an exceptionally broad temperature range from -30°C to +85°C. Its storage temperature also spans -30°C to +85°C, effectively preventing liquid crystal from crystallizing in frigid environments or degrading under high heat—making it ideal for long-haul transportation and harsh storage conditions.
Core Product Highlights and Technical Advantages
- Industrial-Grade Wide Temperature Tolerance: Engineered to maintain strict response times, high contrast ratios, and structural stability across a wide thermal spectrum (-30°C to +85°C). In most application environments, it can start up and display normally without the need for additional heating pads or cooling fans.
- Genuine Native Circular Design: The pure circular geometry delivers perfect visual aesthetics for modern circular hardware products while optimizing internal structural space—completely eliminating the dead corners and spatial waste associated with traditional rectangular screens cut into circular shapes.
- Superior Full Viewing Angle Visibility: The Normally Black mode ensures uniform light output, maintaining high contrast and clarity even under complex indoor lighting, low-light conditions, or extreme side-angle viewing—enabling users to monitor core data in real time with ease.

- Smart Energy and Commercial Charging Terminals: Applicable to auxiliary billing screens on commercial charging piles, indoor/semi-outdoor energy storage system (BMS) monitors, and central control displays for three-phase smart meters. These devices are typically powered by mains electricity or large-capacity batteries, perfectly matching the high-efficiency demands of MIPI-interface main controllers.
- Medical Devices and Health Monitoring Equipment: Can be integrated into circular portable patient monitors, laboratory analytical instrument panels, and smart display consoles for high-end fitness equipment—ensuring accurate presentation of critical medical data across varying operating temperatures.
Technical Q&A for Wide Temperature Round TFT Display
Q1: What is a “Wide Temperature” LCD screen?
A1: A Wide Temperature LCD display utilizes specially formulated liquid crystal materials and structurally reinforced substrate packaging processes. The liquid crystal molecules do not freeze, solidify, or become sluggish under extremely cold conditions, nor do they lose molecular alignment order under extremely high temperatures.
Q2: Can I drive this 1.3-inch circular screen with an ordinary 8-bit or 16-bit parallel MCU directly?
A2: No. Although the ST77916 driver chip natively supports multiple interfaces at the architectural level, this particular TFT-H013A08ZNIST2C16 module has only the physical MIPI-1 Lane interface wired out on the flexible printed circuit board pin design. This means that despite the chip’s other communication possibilities, the hardware configuration is fixed as a high-speed differential serial link. Therefore, ordinary 8-bit/16-bit low-end microcontrollers, which lack physical MIPI interfaces, cannot drive this module directly. You must choose a mid-to-high-end main processor with a native MIPI D-PHY hardware interface layer to output the required video stream signals and properly illuminate this module.
