Low Voltage Custom Programmable COG LCD Display
Low-voltage customizable programmable COG liquid crystal display is
a liquid crystal display module using the Chip-on-Glass (Chip on
Glass) process. Its core advantage lies in the direct bonding of
the driving IC to the glass substrate, combined with low-voltage
power supply and programmable control. It features
ultra-lightweight, low power consumption, and high integration, and
is suitable for small-sized intelligent devices with limited space.

Product Core Features
Core Technology and Structure
The COG technology eliminates the independent PCB and redundant
connections of traditional LCD. The driving IC is directly bonded
to the glass substrate, and the module thickness can be as low as
1.2-1.8mm, which is about 50% thinner than the traditional TAB
module, significantly saving installation space. It is suitable for
devices with sensitive volume requirements.
Low Voltage Characteristics
The standard working voltage is mostly 3.0-3.3V, and some support a
wide voltage range of 2.4-5.5V. It can be adapted to mainstream
MCUs without level conversion, reducing the complexity of power
supply design. Combined with sleep/power-saving modes, the static
power consumption can be as low as microampere level, extending
battery life.
Programmable Capability
Equipped with controllers such as ST7565R, UC1617S, and IST7920,
supporting 6800/8080 parallel and SPI/I2C serial interfaces. It can
be customized for characters, graphics, animations, and display
parameters through instructions, and is compatible with mainstream
development platforms such as Arduino and STM32. It has abundant
open-source driver resources.
Customization Dimensions
Can be customized for display size (such as 0.96-2.8 inches),
resolution (common 128x64, 128x128, etc.), dot matrix layout,
backlight color (white/yellow-green/blue, etc.), FPC pins and
length, viewing angle (6:00/12:00), working temperature (industrial
grade -20°C to +70°C), and communication interfaces to meet
differentiated scenarios.
Display and Reliability
Mainly uses FSTN/STN single-tone (black/white/blue background white
text, etc.), semi-transparent/fully transparent/reflective options.
It has high contrast and strong readability. Industrial-grade
models can withstand -30°C to +80°C storage temperatures, have
strong anti-interference ability, and comply with RoHS
environmental standards.
Core Application Scenarios
- Smart Wearable Devices: Used in smart watches, bracelets, health monitoring devices, etc.,
3.3V low power consumption adapted to button batteries,
ultra-lightweight fitting the watch band/body, programmable display
heart rate, steps, messages, etc., supports custom UI and icons.
- Portable Medical Instruments: Adapted to blood glucose/blood pressure meters, blood oxygen
meters, portable ultrasound, etc. High contrast display of
physiological data, wide temperature range and anti-interference
ensure stability in clinical environments, and customized UI meets
the visualization needs of medical data.
- Industrial Control and Instruments: Used in PLC panels, frequency converters, power meters, sensor
terminals, etc. Low voltage adapted to industrial power supply,
programmable display of real-time parameters, alarm information.
The COG structure can withstand vibration and dust, and the
interface is flexible to adapt to industrial control hosts.
- Smart Home and Security: Used in smart locks, thermostats, gas/water meters, etc. Small
volume embedded in the panel, low power consumption adapted to
battery power supply, customizable display menus, usage data, and
alarm prompts, SPI/I2C interface simplifies and connects with the
main control.
- Automotive Electronics: Applied in tire pressure monitoring, head-up display (HUD), seat
adjustment panels, etc. Wide temperature range and
anti-electromagnetic interference, low voltage compatible with 12V
to 3.3V power supply from the vehicle, programmable display of
vehicle status parameters, improving the efficiency of reading
driving information.
- DIY and Embedded Development: Compatible with development boards such as Arduino/STM32, used for
mini oscilloscopes, logic analyzers, retro game consoles, etc.
Supports custom graphics and animations. In SPI mode, only 4-5
wires are needed to drive, enabling quick prototyping verification.
Frequently Asked Questions
I want the LCD display 8 digits and the outline size is
65x30x2.8mm. Is this possible?
No problem. Firstly, please kindly send us your
specification/drawing paper. If you have not the specification, you
can also provide your samples; we will recommend the suitable one
if it is standard products. Or we can customize for you based on
your own requirement.
This LCD is just what we want, but it is big size, do you have any
smaller size? And the display content need to be changed a little.
For the segment type LCD module, if you need modify the outline
size or display content, a new LCD glass module is need. We have to
open new tooling for you.
This LCD display is HTN type, but I want STN type, can you make?
That's all right. We can change for you as per you request.
I want customize a new LCD module. Can you do?
Yes, we can. Please send your drawing paper. If you have not,
please advise me the outline size of the LCD display, display
information (Glass thickness, Polarizer, Display Type, Connector
mode, Storage Temp. Operating Temp. Supply Voltage, Viewing
direction, drive condition), we can customize for you.
What is leading time for tooling?
General speaking, it will cost 15 to 25 days after drawing paper
confirmation and tooling charge payment, we can report you the
exact time when you confirm the drawing paper.
Can you send us samples for checking?
Yes. Samples order is available.
What is the Leading Time?
If we have stock for the standard ones, the leading time is one day
after payment. If it is the mass production for special ones, the
leading time is about 15-30 days. Suppose we can finish earlier, we
will report the information in advanced.
