Description

The WO1602G series is a COG (Chip-on-Glass) I2C interface LCD display module with a metal pin connection, featuring a display format of 16 characters x 2 lines. This module is equipped with an ST7032i controller IC and supports the I2C interface.

The I2C LCD module of WO1602G has outline dimensions of 74.2 x 25.2 mm, with a view area size of 61.0 x 15.1 mm and an active area size of 56.2 x 11.5 mm. The supply voltage for logic (VDD) can be selected as either 3V or 5V. It operates with a 1/16 duty cycle and 1/5 bias. Operating temperatures for this module range from -20℃ to +70℃, with storage temperatures ranging from -30℃ to +80℃.

COG LCD structures offer several advantages:
 
  • Space Saving: COG technology enables the placement of the chip behind the LCD, eliminating the need for external packaging and saving space.
  • Enhanced Performance: COG reduces interference and backlight effects on LCDs, improving performance, stability, and enhancing image quality and color representation.
  • Faster Manufacturing: COG technology reduces assembly and testing time, leading to faster manufacturing, increased productivity, and lower costs.
  • Price Advantage: The absence of external packaging in COG structures contributes to cost reduction, providing a competitive price advantage.
 

LCD structures with COG not only save space but also offer a price advantage, making them the preferred technology for a wide range of LCD products.

The 16x2 LCD displays in the WO1602G series, supporting I2C interface, come with different LED backlight options available in various colors. Feel free to reach out to us through our website.

SPECIFICATIONS

Interface Pin Function

Pin No. Symbol Level Description
1 VOUT   DC/DC voltage converter. Connect a capacitor between this
terminal and VIN when the built-in booster is used.
2 CAP1N   For voltage booster circuit(VDD-VSS)
External capacitor about 0.1u~4.7uf
3 CAP1P  
4 VDD 3.0/5.0V Power supply
5 VSS   GND
6 SDA   (In I2C interface DB7 (SDA) is input data.
SDA and SCL must connect to I2C bus (I2C bus is to connect a resister between SDA/SCL and the power of I2C bus ).
7 SCL   (In I2C interface DB6 (SCL) is clock input.
SDA and SCL must connect to I2C bus (I2C bus is to connect a resister between SDA/SCL and the power of I2C bus ).
8 RST   RESET (Low active)
