Product Overview
This 3.2-inch SPI TFT liquid crystal display is a versatile small-sized display device ideal for various applications requiring clear visual interfaces.
Size and Resolution: The diagonal size is 3.2 inches with 240×320 pixel resolution, providing clear image and text display suitable for applications with moderate display area and accuracy requirements.
Interface Type: Features ZIF (Zero Insertion Force) FPC (Flexible Printed Circuit) with 18 pins for convenient connection and disassembly, offering high reliability and flexibility with adaptable installation options.
Driver IC: Compatible with ST7789V or ILI9341 driver chips. ST7789V provides stable performance and efficient LCD driving with multiple interface options. ILI9341 supports 262K color display with extensive data capabilities and strong community support for development.
Display Technology: Utilizes TFT (Thin Film Transistor) liquid crystal display technology with fast response speed, vibrant colors, and high contrast. The SPI (Serial Peripheral Interface) communication requires minimal signal lines, conserving MCU pin resources.

Frequently Asked Questions
I want the LCD display 8 digits and the outline size is 65×30×2.8mm. Is this possible?
Yes, we can accommodate your requirements. Please provide your detailed specifications or drawing. If you don't have specifications, you can send samples and we'll recommend suitable standard products or customize according to your needs.
This LCD is what we want, but it's too large. Do you have smaller sizes? Also, we need to modify the display content slightly.
For segment type LCD modules requiring size modifications or display content changes, we will need to create new LCD glass modules, which involves opening new tooling.
This LCD display is HTN type, but I want STN type. Can you manufacture this?
Absolutely. We can modify the display type according to your specific requirements.
I want to customize a new LCD module. Can you do this?
Yes, we specialize in custom LCD modules. Please provide your drawing or specifications including outline size, glass thickness, polarizer type, display type, connector mode, temperature specifications, supply voltage, and viewing direction requirements.
What is the lead time for tooling?
Typically, tooling requires 15 to 25 days after drawing confirmation and tooling charge payment. We will provide exact timelines upon drawing approval.
Can you send samples for evaluation?
Yes, sample orders are available for quality verification and testing.
What is the lead time for orders?
For standard products in stock, lead time is one day after payment. For mass production of custom orders, lead time is approximately 15-30 days. We will notify you promptly if we can complete orders earlier than expected.
Your message must be between 20-3,000 characters!
