Graphic Controller

We are developing graphic controllers specifically to meet the needs of the automotive, Home Appliance, and amusement machine markets.

Automotive, Home Appliance

The VC series is a pattern graphic controller with built-in VRAM that makes it possible to build high-quality animated GUIs with inexpensive parts.
Conventional graphics controllers required the development of a complex display controller program, but the VC series makes it possible to control the display position, scale,
transparency, gradation, and other aspects with a 12-bit property value, enabling the creation of high-quality graphics displays with minimum load on the CPU.
