Functions

1

VB1-

Power

LCD Bias voltages. These are the voltage source to provide SEG driving currents. These voltage are generated internally. Connect capacitors of CBX value between VBX+ and VBX-.
The resistance of these four traces directly affects the SEG driving strength of the resulting LCD module. Minimize the trace resistance is critical in achieving high quality image.

VB1+

3

VB0-

4

VB0-

5

VLCD

Power

Main LCD power supply. Connect these pins together.

6

VBais

I

This is the reference voltage to generate the actual SEG driving voltage.

7

VSS

Power

Ground. Connect Vss and Vss2 to the shared GND pin.

8

VDD

Power

VDD supplies for digital logic and display data RAM.

9

D7

I/O

Bi-directional bus for both serial and parallel host interfaces.
In serial modes, connect D[0] to SCK, D[3] to SDA.

FAQ:

1.What is the application for 240x120 chip on glass LCD display?

It can be used in smart watch,any wearable intelligent equipment,embedded systems,industrial device,security,medical and hand-held equipment.

2.Have you got Rohs complaint for your products ?

Yes, We provide full ROHS& REACH compliant products .

3.What is a graphic LCD display module ?

A graphic LCD display module is typically required when the display of more than just text is required. Many of the LCD controllers on board our graphic LCD display modules also include a CGROM (character generator ROM) to be able to easily use character as well as graphics. Some of the graphic LCD displays have the ability to render graphics in grayscale, enabling you to show images and elements of your UI (user interface) with more depth and definition.

4.What is FSTN LCD ?

FSTN (Film-compensated Super-twisted Nematic) provides a sharper contrast than STN by adding a film. The cost is approximately 5% higher than STN. FSTN works great for indoor and outdoor applications and is mainly used in graphic displays and higher end products.
