On-Screen Display with Auto-Sizing Controller
GENERAL DESCRIPTION
MTV030 is designed for monitor applications to display built-in characters or fonts onto monitor screens. The display operation occurs by transferring data and control information from the micro-controller to RAM through a serial data interface. It can execute full-screen display automatically, as well as specific functions such as character background, bordering, shadowing, blinking, double height and width, font by font color control, frame positioning, frame size control by character height and row-to-row spacing, horizontal display resolution, full-screen erasing, fade-in/ fade-out effect, windowing effect, shadowing on window and full-screen self-test pattern generator. MTV030 provides true 512 fonts including 496 standard fonts and 16 multi-color fonts and 2 font sizes, 12x16 or 12x18 for more efficacious applications. So each one of the 512 fonts can be displayed at the same time. The full OSD menu is formed by 15 rows x 30 columns, which can be positioned anywhere on the monitor screen by changing vertical or horizontal delay. The auto sizing video measurement module measure the timing relationship among HFLB, VFLB, and R, G, BIN at the speed related to the OSD resolution. MCU can get the measurement data, active video, front porth and back porth, through I2C bus read/write operation to keep the appropriate display size and center.
