Dot-matrix LCD Drivers
Overview
The LC7940YC and LC7941YC are segment driver ICsfor driving large, dot–matrix LCD displays. They read 4–
bit parallel or serial input, display data from a controllerinto an 80–bit latch, and then generate LCD drive signalscorresponding to that data.
The LC7940YC and LC7941YC feature mirror–image pinassignments, allowing them to be used together to increasecomponent density. They are designed to be used with theLC7942YC common driver to drive large LCD panels.
Features
• 80 built–in LCD display drive circuits • 1/8 to l/128 display duty cycle • Serial or 4–bit parallel data input • Chip disable for low power dissipation for large–sized
panels • Bias supply voltags can be supplied externally • Operating supply voltage and ambient temperature
- 2.7 to 5.5 V logic supply ( VDD) at Ta = –20 to +85°C- 8 to 20V LCD supply (VDD – VEE ) at Ta = –20 to
+85 °C • CMOS process

LC7940YC, LC7941YC
100 x 240-pixel LCD Panel Application
A 100 × 240–pixel LCD panel requires the following drivers.
• 3 x LC7940YC (or LC7941YC) drivers• 2 x LC7942YC drivers
An example using l/l00 duty cycle is shown below.
1. The LC7942YC chips are cascaded by connectingDIO64 on chip I to DIO1 on chip 2. For a 100–bit shiftregister, O37 to O64 on chip 2 are left open.
2. The LC7940YC (or LC7941YC) chips are cascaded byconnecting CDO on chip I to CDI on chip 2, and CDOon chip 2 to CDI on chip 3. CDI on chip I is tied toGND, and CDO on chip 3 is not used. Thisconfiguration allows the input of 240–bit serial data.

Segment Data Not Multiples of 4 Example.
If this timing data is sent, data elements (m, 229), (m,230), (m+1, 229), (m+1. 230)... will not appear in theoutput (O69 and O70 on chip 3). This is because theLC7940YC (or LC7941YC) converts serial/parallel data
in 4–bit units, which also decreases power dissipation . Fordata that is not a multiple of 4, like 230, the followingscheme is used.
In this case, (m, 231) is output on O71 on chip 3, and (m,232) on O72 on chip 3. However, these outputs are notconnected to the panel and are, therefore, invalid.
