产品概述

COG (Chip-on-Glass) is a display packaging technology where the driver integrated circuit is bonded directly onto the glass substrate of the LCD panel using ACF (Anisotropic Conductive Film) adhesive. By eliminating the separate driver PCB found in conventional LCD modules, COG displays achieve significantly thinner profiles, lighter weight, and smaller footprints — making them the preferred choice for compact, portable, and wearable product designs.

Relialink’s COG LCD modules are available in graphic and numeric segment configurations, with SPI and I2C interfaces for straightforward connection to any microcontroller. Common sizes range from 1.8″ to 3.2″ diagonal, with standard resolutions including 96×64, 128×64, and 132×64. Both positive (dark pixels on light background) and negative (light pixels on dark background) display modes are available depending on backlight color selection.

The thin cross-section and minimal component count make COG modules attractive not only for wearables and portable instruments but also for any product design where PCB space is at a premium and display depth must be minimized.
