240×160 COG LCD 2.6 inch ST7586S

Product Introduction of 240×160 COG LCD

This product is an industrial-grade 240×160 COG LCD monochrome dot matrix display module launched by HOTHMI. The model number is HTG240160R-33W-26C05-V01. This module adopts advanced COG packaging technology, where the driver IC is directly bonded onto the glass panel, significantly reducing the module’s footprint while enhancing shock resistance and operational stability. The display offers a resolution of 240×160 pixels, features an FSTN positive transflective mode, a 12 o’clock viewing direction, and operates with 1/160 duty cycle and 1/11 bias.

The 240×160 COG LCD integrates the ST7586S controller/driver IC, operates at 3.3V, and supports multiple MPU interface modes, including 80-series 8-bit parallel, 68-series 8-bit parallel, 4-wire 8-bit serial, and 3-wire 9-bit serial interfaces. In terms of mechanical dimensions, the overall outline size is 58.4 x 46.4 x 5.6mm, and it comes with a white LED backlight consisting of 3 chips. Furthermore, the module offers excellent environmental adaptability, with an operating temperature range of -20°C to +70°C and a storage temperature range of -30°C to +80°C, making it universally suitable for various low-power, high-definition monochrome graphic display applications in industrial control, smart instrumentation, and portable electronic devices.

Technical FAQ of 240×160 COG LCD

Q1: Does this 240×160 COG LCD module support 3.3V systems or 5V systems?

A1: This display module is designed for low-power modern microcontrollers, with a standard operating voltage of 3.3V (typically allowing a supply range of 3.0V~3.3V). If your host MCU operates at 5V (e.g., some traditional 5V microcontrollers), it is recommended to add level shifterson data and control lines, or use series current-limiting resistors, to prevent high voltage from damaging the internal ST7586S driver IC.

Q2: How do I switch the module from the default parallel interface to serial SPI interface?

A2: You simply need to set the interface configuration pins IF3, IF2, IF1 to the appropriate logic levels via hardware. For example, if you plan to use 4-wire SPI serial bus, connect IF3 to low level (VSS), and both IF2 and IF1 to high level (VDD1). In serial mode, some of the parallel data bus pins (DBx) will automatically function as SCL (clock) and SDA (data) lines, significantly saving MCU I/O pin resources.
