11.18. MC141585
11.18.1. General description
This is a high performance HCMOS device designed to interface with a micro controller unit to allow
colored symbols or characters to be displayed onto a LCD monitor. Because of the large number of fonts,
512 fonts including 496 standard fonts and 16 multi-color fonts, LMOSD2-16 is suitable to be adopted for
the multi-language monitor application especially. It minimizes the MCU?s burden through its built-in RAM.
By storing a full screen of data and control information, this device has a capability to carry out ?screen-
refresh? without any MCU supervision. Programmable hatch pattern generator is added for individual pixel
inspection.
Since there is no clearance between characters, special graphics oriented characters can be generated by
combining two or more character blocks. The full OSD menu is formed of 15 rows x 30 columns which can
by freely positioned on anywhere of the monitor screen by changing vertical or horizontal delay.
Special functions such as character background color, blinking, bordering or shadowing, four-level
windows with programmable size, row double height and double width, programmable vertical height of
character and row-to-row spacing, and full-screen erasing and Fade-In/Fade-Out are also incorporated.
There are 8 color selections for any individual character display with row intensity attribute and window
intensity attribute to expand the color mixture on OSD menu.
