Description

The KD125 is a member of LCD driver IC series developed by King Billion Electronics Co. It's a
120-output common/segment LCD driver IC suitable for driving small/medium scale dot matrix LCD panels, used in PDA or electronic dictionary. The KD125 is good as a segment driver, common driver or common/segment driver, and it can create a low power consuming, high-resolution LCD. The KD125 have eight modes can selected to set common and segment numbers by control register. The KD125 also has built- in analog regulator and DC/DC converter and they can be enabled or disabled to use external LCD power system for larger LCD panel.
