LCD Monitor On-Screen
Display II - 16 (LMOSD2-16)
CMOS
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 mulit-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 posi-
tioned 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 spac-
ing, 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.
