Super On-Screen-Display for LCD Monitor MTV121 is designed for LCD monitor applications to display the built-in characters or fonts onto an LCD monitor screen. The display operation is by transfer- ring data and control information from micro control- ler to RAM through a serial data interface. It can execute full screen display automatically and spe- cific functions such as character background color, 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 and shadowing on window. MTV121 provide 256 standard and 16 multi-color fonts for more efficacious applications. The full OSD menu is formed of 15 rows x 30 columns which can be positioned on anywhere of the monitor screen by changing vertical delay or horizontal delay. Moreover, MTV121 also provide 8 PWM DAC channels with 8 bits resolution and a PWM clock out- put for external digital to analog control.
