This design allows them to occupy minimal space while connecting crucial components such as the motherboard, display, keyboard, and touchpad. In the LG Gram, which is celebrated for its ultra-slim form factor and lightweight design, ribbon cables play a vital role in enabling these compact dimensions.
The ribbon cables in LG Gram models are specifically engineered to support their high-performance functionality. For example, they are responsible for transmitting data between the motherboard and the device’s high-resolution WQXGA display in models like the LG Gram 17. Their robust yet flexible nature ensures durability, even in such thin and portable designs.
