Benefits of GU-U100 vs LCD

Display for Best Readability

GU128X60E-U100 is inteded for applications with 128×64 LCD graphic display that have poor readability and/or rapidly changing content. GU128X60E-U100, being emissive display is viewable from wide angles solving readability problem. The response time and refresh rate is also faster than 128×64 LCD graphic displays, eliminating ghost images from the display.

What makes GU128X64E-U100, 128×64 VFD graphic display for best readability?

  • Easy to read high contrast display.
  • High brightness. Unlike the LCD graphic display, only the dots that are ON are brighter, not the entire display.
  • Color filter can alter the illumination color and increase the contrast of the display.
  • Wide viewing angle display. The display content WILL NOT wash-out like the LCD graphic display.
  • Faster display response time and refresh rate allowing data to display clearly.

Reduce the development time

Replacing from 128×64 Graphic LCD

GU128X64E-U100 supports KS0108 commands and has the same footprint making transition from LCD graphic display an ease.

For New design

GU128X64E-U100 is simpler to connect requiring a single 5V power supply, no contrast adjustment, and 3 types of serial interfaces requiring fewer pins. Serial and parallel interfaces are included in the code library with manufacturer recommended timings.

Interfaces

GU-U100 supports parallel and three types of serial interfaces. Three types of serial interfaces are: Serial Type 1: CU-UW, Serial Type 2: SPI, and Serial Type 3: Signal Separate. Interfaces are set via jumper.

Code library is available with manufacturer recommended timings.

Parallel

Parallel uses the most pins but provides the most direct connection. Each signal line is controlled by a separate pin.
Code that was written for LCDs will use the parallel interface.

Pin No. Symbol Function description
1 VSS Ground
2 VCC Power supply
3 NC Not Connected
4 RS Register Select: command(0) / data(1) signal
5 RW Read/Write select: write(0) / read(1) signal
6 E Enable signal
7-14 DB0-DB7 Bi‐directional 8‐bit data bus
15 CS1 Chip Select 1 (left side), active high
16 CS2 Chip Select 2 (right side), active high
17 /RST Reset module, active low
18-20 NC Not Connected

Serial Type 1: CU-UW

This interface uses the minimum number of pins, but requires up to two bytes to be sent per data item or command. Data is input and output over the same line.

The /CS (chip select) here is for the entire module. It is not the same as /CS1 or /CS2.

A command byte it sent when /CS is lowered. This status byte sets the state of /CS1, /CS2, RW, and RS. After the status byte, commands and data bytes are sent or received. The status byte must be sent when /CS is raised or the status of /CS1, /CS2, RW, or RS needs to change.

Pin No. Symbol Function description
1 VCC Power supply
2 SI/SO Data input/output
3 VSS Ground
4 /CS Module chip select
(not to be confused with /CS1 and /CS2)
5 SCK Synchronous serial clock
6 /RST Reset module, active low
7-9 NC Not Connected

Serial Type 2: SPI

This interface allows you to use the module on an SPI bus as two slave devices selected by /CS1 and /CS2. Data is sent to the module on a separate line from data received from the module.

SO, SCK, /RST, /CS1, /CS2, and SI lines are used.

A command byte similar to the Type 1 interface must be sent to change RW and RS. After the status byte, commands and data bytes are sent or received. The status byte must be sent when /CS1 or /CS2 changes or when RW or RS need to be changed.

Pin No. Symbol Function description
1 VCC Power supply
2 SO Output (data/status) sent from the module to the host
3 VSS Ground
4 NC Not Connected
5 SCK Synchronous serial clock
6 /RST Reset module, active low
7 /CS2 Chip Select 2 (left side), active low
8 /CS1 Chip Select 1 (right side), active low
9 SI Input (data/commands) sent to the module from the host

Serial Type 3: Signal Separate

This has the potential to be the fastest serial interface since no status byte ever need be sent.

Since there is no pin to output from the module, there may be restriction such as not able to read the display memory when using this interface. This interface has fast refresh rate and is primarily useful for pre-rendered high-speed animation.

RS, SCK, /RST, CS1, CS2, and SI lines are used.

Pin No. Symbol Function description
1 VCC Power supply
2 NC Not Connected
3 VSS Ground
4 RS Register Select: command(0) / data(1) signal
5 SCK Synchronous serial clock
6 /RST Reset module, active low
7 /CS2 Chip Select 2 (left side), active low
8 /CS1 Chip Select 1 (right side), active low
9 SI Input (data/commands) sent to the module from the host
