Product Description

Key Features of Color Segment VA LCDs:

High Contrast and Vibrancy: Rich colors on a deep black background for excellent readability.

Color-Coded Segments: Supports multiple colors (e.g., red, green, blue, or custom colors) for specific segments or icons, making it ideal for alerts or status indicators.

Wide Viewing Angles: Maintains consistent brightness and color up to 170°, ensuring readability from different perspectives.

Customizable Design: Segments can be tailored to display numbers, icons, and graphical elements in distinct colors.

Integrated Backlighting: Can include multi-color backlights to enhance the visual appeal and usability in low-light environments.

Detailed Parameters:

The following is the analysis of the "High Contrast VA Liquid Crystal Display Black Screen Negative White Segment 3.6V 40PIN" LCD product.

High-contrast VA liquid crystal display:

VA type: VA (Vertical Alignment) is a liquid crystal panel technology. The liquid crystal molecules in this technology are arranged vertically to the substrate when no electricity is applied. VA type liquid crystal displays have the characteristic of high contrast. Usually, the static contrast can reach between 2500:1 and 3000:1, which can present clearer and richer dark details, purer black, and more distinct overall picture contrast.
High contrast: High contrast enables the image to perform well when displaying dark or dim scenes, such as when watching movies or playing games, allowing the picture to be more realistic and have a stronger sense of depth. This is very important for applications that require high-quality images, such as high-end displays, vehicle-mounted displays, etc.

Black screen with negative white section:
Black screen: This might refer to a display state or feature of the LCD product, where the screen background is black. Due to the characteristics of VA liquid crystal display, it can achieve a deeper black, providing a good foundation for negative white display.
Negative white section: Indicates that the displayed content is white, contrasting sharply with the black background, belonging to negative display type. The color of the characters in negative display is usually the color produced by the backlight passing through the glass, so negative display generally requires backlight to display content. This negative white section display is commonly used in some scenarios where the content needs to be highlighted and readability improved, such as some instrument displays, electronic labels, etc.

3.6V: This is one of the operating voltages or driving voltages for this LCD product. The normal display of an LCD relies on multiple voltage signals, such as VDD (main power supply voltage), AVDD (analog power supply voltage), VCOM (common voltage), etc. 3.6V could be the value of a specific voltage among them, such as possibly the VDD voltage, or a specific voltage after being converted by a charge pump for driving the liquid crystal molecules. The exact value needs to be determined based on the circuit design and specifications of this LCD product.

40PIN: Refers to the number of interface pins of this LCD screen. Common LCD interfaces include RGB, LVDS, MIPI, etc. The definitions and functions of 40PIN for different interface types are also different. For example, an LCD screen with an RGB 40PIN interface generally has a resolution of no more than 1024*600. It requires driving voltages such as AVDD, VGH, VGL, VCOM, etc., and has only one IO voltage of VCC. The FPC may carry a boost circuit on it for driving the LCD screen. The 40PIN interface can provide sufficient signal transmission channels for connecting the motherboard or other driving circuits to achieve control and data transmission of the LCD screen, including transmitting image data, control signals, power supply, etc.

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.
