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.
