Product Details
custom STN energy meter display segment wide temperature LCD Module
Product Description
1. LCD Panel (Liquid Crystal Display):
- This type of LCD module consists of liquid crystals sandwiched
between two layers of polarized glass. The liquid crystals align
when an electric current is applied, allowing light to pass through
or blocking it, thus creating visible numbers or symbols.
- Without a backlight, the display relies on ambient light to be
visible. This makes it suitable for use in environments where the
display is exposed to sufficient lighting, such as in bright rooms
or where artificial lighting is present.
2. No Backlight(optional):
- Unlike more advanced LCD modules, this simpler design does not have
a backlight. Instead, the display relies solely on external light
to illuminate the characters on the screen.
- This makes the display highly power-efficient, as no energy is
required to produce light for the display itself. It's a key
feature for battery-operated electric meters or situations where
low power consumption is critical.
3. Single Integrated Circuit (IC):
- The display module is driven by a single IC, which is responsible
for controlling the liquid crystal panel. This IC is relatively
simple and serves to process the data from the electric meter's
sensors (like current or voltage) and display it in a readable
format.
- The IC controls the orientation of the liquid crystals to show
numeric values for energy consumption (kWh), voltage, or current.
4. Display Format:
- The display is usually alphanumeric, showing basic numeric values
such as energy usage or other measurement units, often in a
7-segment or dot matrix format. These simple displays provide clear
and easy-to-read data but are limited in the amount of information
they can show.
- Since there is no backlight, the display is best suited for
environments with adequate natural or artificial light.
5. Power Efficiency:
- One of the primary advantages of this type of LCD module is its
extremely low power consumption. Without the need for backlighting,
the module only draws power to drive the liquid crystals, making it
an ideal choice for applications where energy efficiency is
crucial.
- These types of displays can be used in battery-powered electric
meters, where power conservation is a top priority.
6. Simplicity and Durability:
- The design is simple and robust, with fewer components to fail.
This simplicity ensures reliability and longevity, which is
essential for electric meters that may need to function for years
without maintenance.
- The display can handle typical environmental conditions, like
temperature fluctuations, and operates in a wide range of
conditions without the need for special housing or protection.

Applications
Response Time: TN displays have fast response times, typically
between 1ms and 5ms. This makes them suitable for fast-paced gaming
and action-packed videos, as they can handle rapid motion without
significant motion blur.
Refresh Rate: TN displays often offer high refresh rates, such as
144Hz or 240Hz. A higher refresh rate provides smoother on-screen
motion and reduces visual artifacts like screen tearing.
Contrast Ratio: TN displays generally have lower contrast ratios
compared to other display technologies like IPS (In-Plane
Switching). This means that TN displays may have less vibrant
colors and poorer viewing angles.
Viewing Angles: TN displays have limited viewing angles, especially
in the vertical direction. When viewed from off-center angles, the
colors and contrast may appear distorted or washed out.
Cost: TN displays are typically more affordable compared to other
display technologies like IPS or OLED (Organic Light-Emitting
Diode). This makes them popular in budget-oriented devices or in
scenarios where fast response times are prioritized over other
factors.
