Description
Product Introduction
The HOTHMI TFT-H028A16QVIST4C10 is a 2.8-inch IPS TFT capacitive touch display that integrates full-viewing-angle technology, 240×320 resolution, 400 cd/m² high brightness, and NTSC 70% wide color gamut. It features a streamlined 4-wire 8-bit serial interface and embeds the mature ST7789T and GT911 driver chips, enabling smooth 5-point touch and vivid graphic rendering. With a wide operating temperature range of -30℃ to +80℃ and an ultra-slim profile of just 3.95 mm, this IPS TFT module perfectly addresses the demanding requirements of smart home control panels, industrial handheld instruments, medical monitoring devices, and IoT human-machine interaction terminals for high-performance display and easy development.
Core Highlights
Premium IPS TFT Wide Viewing Angle for No-Blind-Spot Visual Experience
The most outstanding highlight of this display is its adoption of IPS panel technology. Unlike TN screens that suffer from severe whitening or darkening when viewed off-angle, this IPS TFT display delivers exceptional viewing angles. Whether you are operating the device head-on, or viewing from the side, top, or bottom, the color, brightness, and contrast remain consistent, with true-to-life colors and no hue shift. Combined with 240(RGB) x 320 resolution and 70% NTSC color gamut coverage, this IPS TFT screen not only renders data with sharp clarity but also produces vivid and rich colors when displaying images and graphical interfaces.
Core Driver ICs: ST7789T + GT911- A Powerful Combination
The display integrates the ST7789T display driver IC. Major development ecosystems such as Arduino Adafruit and STM32 HAL offer a wealth of reference examples, requiring only simple parameter adjustments for rapid debugging. Additionally, this IPS TFT screen comes standard with capacitive touch, powered by the GT911 touch driver IC. The GT911 supports sensitive 5-point capacitive touch, including single-tap, double-tap, swipe (up/down/left/right), and long-press gestures, significantly enhancing the interactive quality of your end product.
Industrial-Grade Wide-Temperature Design Built for Harsh Environments
This IPS TFT module has undergone rigorous testing and features an operating temperature range of -30℃ to +80℃, with storage temperatures from -30℃ to +85℃. This specification makes it a true industrial-grade component, suitable for outdoor equipment, frigid regions, or high-temperature cabinets, ensuring long-term system stability and reliability.
Ultra-Slim and Compact Form Factor with Simplified Connectivity
In terms of physical specifications, the overall thickness of the IPS TFT screen is only 3.95±0.3 mm, with outer dimensions of 50.00 mm x 69.20 mm and an active display area of 43.20 mm x 57.60 mm.
Pin Definition
This IPS TFT screen connects via a 10-Pin FPC interface, with pin assignments from Pin_1 to Pin_10 as follows:
Application Fields
Thanks to its excellent display performance, ease of driving, and industrial-grade reliability, this 2.8-inch IPS TFT display finds broad application prospects across multiple industries:
- Smart Home and Intelligent Control Panels: Used in smart thermostats, video intercom door panels, and intelligent lighting control hubs. The IPS wide-viewing-angle ensures that family members can clearly read data on the screen from various angles.
- Industrial Automation and Instrumentation: Serves as a handheld display module for portable oscilloscopes, digital multimeters, and PLC programmers. The wide-temperature range guarantees stable operation in harsh factory environments.
- Medical and Healthcare Devices: Suitable for handheld health monitors, portable oximeters, home-use blood glucose meters, blood pressure monitors, and other compact precision medical terminals. The sharp and clear display facilitates accurate reading of various monitored parameters.
Technical FAQ
To help you better understand this IPS TFT display, we have compiled the following common technical questions and answers:
Q1: What are the backlight power requirements for the display?
A1: The recommended backlight operating conditions are Vf = 3.0~3.3V, If = 120 mA. You can power it directly from the system’s 3.3V supply, but to protect the backlight LEDs, it is best to place a suitable current-limiting resistor in series or use a MOSFET with a PWM signal for brightness dimming.
Q2: What touch gestures does this IPS TFT screen support?
A2: Equipped with the GT911 capacitive touch controller, this IPS TFT screen typically supports multi-touch, single-tap, double-tap, swipe, and other common gestures.
Q3: Your screen has a wide storage and operating temperature range. Does it require special power management?
A3: No special power management is needed. As long as the VDD and VCI voltages are stable within the 3.0±0.3V range, the IPS TFT display will operate normally. At -30℃, the response time of the liquid crystal molecules may slow slightly, but the display will still maintain normal functionality, meeting industrial-grade requirements.
