COG+PIN Black Segmented LCD Display ST7035 I2C

How COG Segment LCDs Work?

1. Glass Substrate:

   • The display is built on a glass panel containing liquid crystal cells.

2. Integrated Driver:

   • The driver IC is mounted directly on the glass, which controls the individual segments of the LCD. This eliminates the need for a flexible PCB (printed circuit board) or external wiring between the glass and the driver, reducing complexity.

3. Polarization:

   • The liquid crystals are aligned between two polarizing layers. When voltage is applied to the segments, the crystals align in a way that blocks or allows light to pass, creating the visible segments.

4. Segment Configuration:

   • The display typically includes a matrix of segments that can be activated or deactivated to form numbers, letters, or custom symbols.

Advantages of COG Segment LCDs:

1. Space-Saving:

   • Compact design with integrated circuitry makes it ideal for devices where space is limited.

2. Low Power Consumption:

   • Highly energy-efficient, suitable for battery-operated applications.

3. Enhanced Durability:

   • More robust against mechanical stress compared to traditional displays with external driver ICs.

4. Improved Aesthetics:

   • Sleek design with fewer external connections, resulting in a cleaner look.

5. Cost-Effective for Mass Production:

   • Reduced complexity in assembly due to the integration of the driver IC on the glass.
