1.6-inch 400×400 RGB interface round TFT screen liquid crystal
module is a small circular color liquid crystal display component
with high resolution and excellent color performance. Here is its
detailed introduction:
Dimensions: The diagonal size is 1.6 inches, and the effective
display area has a diameter of approximately 39.84mm.
Resolution: 400×400 pixels, meaning there are 400 pixel points both
horizontally and vertically on the circular screen, providing a
relatively clear image display effect.
Interface type: Uses RGB interface, capable of connecting with
various microcontrollers and development boards, facilitating data
transmission and control.
Brightness and contrast: The general brightness is around 300cd/m²,
and the contrast ratio can reach 800:1, providing good visibility
in different ambient light conditions.
Viewing angle: Mostly IPS full viewing angle, with viewing angles
of 80°/80°/80°/80° on the left, right, top, and bottom
respectively. When viewing the screen from any angle, the color and
brightness of the image change little.
Operating temperature: The normal operating temperature range is
typically between -20℃ and 70℃. Some products can support a wide
temperature range of -30℃ to 80℃.
Display Principle:
The TFT screen precisely controls the transparency of each pixel
through a thin-film transistor array. Combined with backlight and
filters, it realizes image display. The LED backlight module emits
white light, which is evenly diffused by the light guide plate.
After passing through the vertical polarizer, the light becomes
single-directionally polarized light. The liquid crystal layer
changes the molecular arrangement under voltage control, rotates
the polarization direction of the light, adjusts the light
transmission intensity. The row driver sequentially turns on the
TFT switch, and the column driver writes the grayscale voltage into
the pixel capacitor. The storage capacitor maintains the voltage,
ensuring the stable deflection of the liquid crystal molecules. The
transmitted white light is decomposed into the three primary colors
by the RGB color filter, and then mixed to form a full-color image.
Application fields:
Smart wearable devices: such as smart watches and smart bands, with
circular screens designed in accordance with ergonomics, are easy
to wear and operate, and can display time, health data,
notifications, etc.
Smart home devices: can be used as control panels for smart
appliances, such as smart ovens and smart washing machines, to
achieve human-computer interaction and display function menus,
operating status, etc.
Vehicle display screens: suitable for car dashboards, in-vehicle
multimedia systems, etc., to display vehicle speed, fuel
consumption, navigation information, etc.
Instrumentation: in some small instruments and meters, such as
electronic thermometers and smart electricity meters, they are used
to display measurement data and working status.
FAQ:
1. I want the LCD display 8 digits and the outline size is
65x30x2.8mm………?
Answer: 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.
2.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.
Answer: 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.
3. This LCD display is HTN type, but I want STN type,can you make?
Answer: That’s all right . we can change for you as per you request.
4. I want customize a new LCD module. Can you do?
Answer: 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.
5. What is leading time for tooling?
Answer: 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.
6. Can you send us samples for checking?
Answer: Yes,. Samples order is available.
7. What is the Leading Time?
Answer: 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.
