23.2
Overview
The LCD Controller/driver is intended for monochrome passive liquid crystal display (LCD) with
up to four common terminals and up to 25 segment terminals.
A simplified block diagram of the LCD Controller/Driver is shown in Figure 23-1 on page 235. For
the actual placement of I/O pins, see 鈥�64A (TQFP) and 64M1 (QFN/MLF) Pinout ATmega169P鈥�
An LCD consists of several segments (pixels or complete symbols) which can be visible or non
visible. A segment has two electrodes with liquid crystal between them. When a voltage above a
threshold voltage is applied across the liquid crystal, the segment becomes visible.
The voltage must alternate to avoid an electrophoresis effect in the liquid crystal, which
degrades the display. Hence the waveform across a segment must not have a DC-component.
The PRLCD bit in 鈥漃RR 鈥� Power Reduction Register鈥� on page 45 must be written to zero to
enable the LCD module.
23.2.1
Definitions
Several terms are used when describing LCD. The definitions in Table 23-1 are used throughout
this document.
Table 23-1.
Definitions
LCD
A passive display panel with terminals leading directly to a segment
Segment
The least viewing element (pixel) which can be on or off
Common
Denotes how many segments are connected to a segment terminal
Duty
1/(Number of common terminals on a actual LCD display)
Bias
1/(Number of voltage levels used driving a LCD display -1)
Frame Rate
Number of times the LCD segments is energized per second.
