Small Size VA LCD Display 3 Line 4 Digits Black Segment Screen
30PIN
Product Description
How to develop a Custom VA LCD Screen:
Determine Backlighting Options
- Backlight type: LED or EL (Electroluminescent) lighting.
- Uniformity and brightness levels based on usage conditions.
- Color matching with the device's branding.
.Design Custom Segments or Graphics
- Work with the manufacturer to define the layout:
- Segments: Numeric, alphanumeric, or symbols.
- Icons: Battery status, alerts, wireless indicators, etc.
- Dynamic elements: Bar graphs or progress indicators.

VA LCD Display: VA (Vertical Alignment) is a type of liquid crystal
display that features high contrast and wide viewing angles,
providing excellent display quality. It is commonly used in devices
such as monitors and televisions.
Small Size: Usually refers to a display with a smaller diagonal
screen size, typically ranging from a few inches to several dozen
inches. Common sizes include 3.5 inches, 5 inches, and 7 inches.
These screens are small in size and have low power consumption,
making them suitable for portable electronic devices and industrial
control equipment.
3-Wire: Generally refers to a screen interface that uses the 3-wire
SPI (Serial Peripheral Interface) communication protocol, which
uses MOSI (Master Device Data Output), SCLK (Clock Signal), and CS
(Chip Select) three lines to achieve data transmission with the
main control chip. This method is suitable for one-way data
transmission scenarios.
4-Bits: Indicates that the screen can display 4-bit numbers or
characters, such as common digital tube displays, which can be used
to display simple numerical information, such as temperature, time,
and counting.
Black Segment Screen: Refers to a screen with black segment codes
for display, usually showing black numbers, characters, or graphics
on a white background. It belongs to a monochrome display type and
has the characteristics of clear display and low power consumption,
commonly used in electronic watches, calculators, and instrument
meters, etc.
30PIN: Refers to a screen with 30 pins. These pins are used to
connect the screen to the circuit board to achieve power supply,
data transmission, and other functions. Different pin arrangements
and definitions correspond to different interface standards and
functions.
