Product Details
This cost-effective 3.5-inch TFT LCD touch screen module utilizes
thin-film transistor technology, offering an optimal balance
between portability and clear visibility. The 320×480 HVGA
resolution delivers vibrant 65K/262K color display capabilities
with precise capacitive touch functionality.
The display supports both SPI serial and MCU parallel interfaces:
SPI requires only 4 wires for communication, conserving
microcontroller IO pins for compact devices, while the MCU parallel
interface enables faster data transmission for rapid screen refresh
rates. With brightness exceeding 300 cd/m² and operating
temperature range of -20ºC to 70ºC, this display provides reliable
performance in demanding environments and meets RoHS and CE
certifications.
Core Applications
- Industrial Control and Instrumentation: Human-machine interfaces for PLCs, frequency converters, and
measurement terminals with touch parameter setting and operation
curve viewing
- Smart Home and Security: Display touchscreens for smart gateways, HVAC control panels,
video intercoms, and monitoring devices
- Embedded Development and Maker Projects: Popular display for Arduino and STM32 development boards in
handheld consoles, GPS devices, and smart home prototypes
- Medical Portable Devices: Applications in blood pressure monitors, oximeters, and ECG
monitors for clear physiological data display
- Vehicle Auxiliary Equipment: Instrument panels for motorcycles, agricultural machinery, and
in-vehicle entertainment systems with vibration and temperature
stability
Frequently Asked Questions
I want the LCD display 8 digits and the outline size is
65x30x2.8mm?
Please provide your specifications or drawing. If unavailable, send
samples and we'll recommend suitable standard products or customize
based on your requirements.
This LCD is just what we want, but it is big size, do you have any
smaller size? And the display content need to be changed a little.
For segment type LCD modules requiring size or content
modifications, new tooling is necessary for custom LCD glass
modules.
This LCD display is HTN type, but I want STN type, can you make?
Yes, we can modify the display type according to your
specifications.
I want customize a new LCD module. Can you do?
We provide complete customization services. Please provide drawings
or specifications including outline size, display information,
glass thickness, polarizer type, connector mode, temperature
ranges, supply voltage, viewing direction, and drive conditions.
What is leading time for tooling?
Tooling typically requires 15-25 days after drawing confirmation
and payment. Exact timelines are provided upon drawing approval.
Can you send us samples for checking?
Yes, sample orders are available for evaluation.
What is the Leading Time?
Standard products in stock ship within one day after payment. Mass
production for custom orders typically requires 15-30 days, with
earlier completion notifications when possible.
