After more than three years of R&D, HONYONE has unveiled its first display push button switch at the Hong Kong International Autumn Electronics Fair this October, drawing strong attention from buyers worldwide. By integrating a micro TFT LCD into a mechanical switch, this product turns a plain button into a smart display unit — capable of showing custom images, animations, status icons, and even short video clips. Several AI server and AI keyboard manufacturers are currently evaluating samples.

For engineers who have been working around conventional illuminated buttons, this is a genuine step up: the button no longer just lights up — it tells you exactly what it does.

• [Product Definition] A compact SPI-programmable switch with a 0.79-inch full-color TFT display — three core breakthroughs:
• Intuitive interaction: a tactile mechanical key that shows images, text and animations
• Minimal assembly: solder-free hot-pluggable adapter board design
• Ultra-compact: 0.79-inch full-color display, built for dense panel layouts

Key Specifications

Six Highlights
1. Crisp micro display
0.79" TFT with 128×128 pixels and a 15.21mm × 15.21mm active area — sharp icons and text in dense panel layouts.
2. 2.5D tempered glass, true-black finish
Scratch-resistant, fingerprint-free, and clearly readable even in direct sunlight.
3. SPI interface, embedded-friendly
Standard SPI bus (SDA/SCL/CS/DC/RESET + PWM backlight) works with ESP32, Arduino and STM32 — light it up the day it arrives.
4. Fully customizable on-screen content
Images,GIF / Frame Animation, status icons and short videos; extensible to WiFi, touch and audio for true smart-switch interaction.
5. Mechanical click feel, up to 5 million cycles
Crisp tactile response for high-frequency use; audible and silent structures are both available.
6. Hot-pluggable adapter board
Board-to-board connection replaces fragile FPC ribbons — faster maintenance, solder-free replacement.

Typical Applications
AI hardware: AI mini-keyboard keys and AI server rack control buttons — each key shows its current function and running status
Industrial control: control panels, controllers, video matrices and matrix switchers
Pro AV: stage lighting consoles and video processor panels
High-end instruments: medical devices and precision instrumentation

1:How do l unainstream dev platforms supported?
Via the standard SPI interface from your host MCU. We provide complete datasheets, demo boards and basic driver code, compatible with ESP32, Arduino and STM32. Wide supply range VCC 2.4–3.3V — light it up the day your samples arrive.

2: Is the screen readable outdoors or in bright workshops?
Yes. The transflective TFT panel, combined with a 2.5D tempered glass cover and true-black finish, uses ambient light reflection to stay clearly readable in direct sunlight — ideal for outdoor and industrial environments.

3:What does the adapter board do? Is assembly and maintenance easy?
It solves the classic pain point of fragile, hard-to-solder FPC ribbons. Solder the hot-pluggable adapter board onto your main PCB once, then plug the display switch in and out board-to-board — faster production assembly and easy solder-free field replacement.

4:Can the and feel be customized for our device?
Absolutely. Both audible and silent structures are available; actuation force (gf), travel and feel curve can be fine-tuned to match your panel cutout and user preference. Mechanical life up to 5,000,000 cycles.

5:What cutting-edge applications is this product used in?
Beyond traditional industrial control panels, stage lighting and medical instruments, it is now widely used in AI server rack control, AI mini-keyboards and smart-home central control panels — displaying dynamic icons, macro combos or real-time system status.

6:What is lead time? Do you support OEM/ODM?
HONYONE (Huizhou Honyone Electric) is an electronic switch source manufacturer with 26 years of experience, offering free sampling with a typical lead time of 10–15 days. Whether you need custom screen UI logic, housing structure or adapter boards, full OEM/ODM support is available.
