    When you begin a project with an lcd round display, think about what you need. Consider what kind of device you are making. Check if your device has space for the display. Make sure your system works with the display. People use round displays in many places. You can find them in stores and malls. They are also used at events and hotels. Offices, theme parks, and museums use them too. Each place needs a different size and resolution. You also need to check if the display works with your system. Power efficiency is important for every project.

    Size and Resolution

    Pick a size and resolution that fits your device. The size depends on how much room you have. Small screens are good for watches and smart home devices. Big screens are better for signs and public places.

    Size

    Resolution

    1.28inch/1.3inch

    240*240

    1.39inch

    360*360

    A higher resolution gives you clearer pictures. Text and graphics look sharper. More pixels use more power. The backlight uses most of the energy. Extra processing for high resolution also uses more power. Try to balance size and resolution with battery life.

    Interface Compatibility

    Check if your lcd round display matches your system. Most round displays use MCU, SPI, TTL, LVDS, DSI, or EDP. Your system on chip must support the same interface. If they do not match, you may need a converter.

    Step

    Description

    1. Submit Requirements

    Provide detailed technical requirements including LCD specifications, input signal, and functional requirements.

    2. Technical Assessment & Quotation

    Evaluate feasibility, confirm signal conversion solutions, and provide design suggestions.

    3. Design Confirmation & Sample Production

    Confirm design and produce samples for testing.

    4. Sample Testing & Feedback

    Test samples and gather feedback for adjustments.

    5. Mass Production & Delivery

    Proceed to mass production based on confirmed designs and requirements.

    Always match the display’s specs with your system and enclosure. This helps you avoid problems when you set up your device.

    Power Consumption

    Power efficiency matters for every lcd round display project. You want your device to last longer. Different displays use different amounts of power.

    Display Technology

    Power Consumption (Example)

    TFT LCD

    ~30W (15-inch)

    Monochrome LCD

    ~1W (similar size)

    OLED

    Nearly 0W (black image)

    E-paper

    ~4mW (during update)

    Traditional LCD

    ~400mW (similar size)

    Bar chart comparing power consumption of TFT LCD, Monochrome LCD, OLED, E-paper, and Traditional LCD.

    Pick a display that fits your power needs. Battery-powered devices need displays that use less energy. If you want bright and colorful images, you may need more power.

    Tip: Test your display in real life. See how long the battery lasts. Check how the display looks in your device.

    Performance Factors

    Brightness and Contrast

    You should check the brightness and contrast before picking your lcd round display. Brightness shows how easy it is to see the screen in different places. If you use your lcd round display outside, you need a very bright screen. The table below lists how bright your display should be for outdoor use:

    Application

    Environment

    Recommended Brightness

    Outdoor public space

    Direct sunlight

    up to 1000 cd/m²

    Outdoor

    -

    5,000 to 8,000 nits

    Outdoors with direct sun

    -

    Above 8,000 nits

    Contrast helps you see details on the screen. A higher contrast ratio makes words and pictures easier to see. You should pick a display with a contrast ratio of at least 10 to read things well. The table below shows how different contrast ratios change how easy it is to read:

    Contrast Ratio

    Readability Level

    5

    Acceptable

    10

    Well readable

    15

    Outstanding

    20

    Excellent

    Close to 1

    Unreadable

    Tip: Choose a round display with high brightness and contrast if you want clear pictures in bright places.

    Viewing Angles

    Viewing angles tell you if you can see the screen from the side. If your display is in a car or a watch, good viewing angles are important. You want everyone to see the screen clearly, even from the side. The table below explains why viewing angles matter:

    Application

    Impact of Poor Viewing Angles

    Automotive Displays

    Colors may shift, contrast may degrade, and brightness can drop, affecting navigation visibility.

    Medical Devices

    Multiple professionals need clear visuals to avoid misinterpretation of patient data.

    You should test your lcd round display in your device. Make sure colors and brightness look the same from every angle. Good viewing angles help people use your device safely and easily.

    • Wide viewing angles give you better results.

    • Your display stays sharp and bright from all sides.

    • You do not have problems with color or contrast changes.

    Response Time

    Response time tells you how fast your display reacts when you touch it or when images move. A lower response time means your display works faster. You want a display with quick response time for smooth movement and fast touch actions. The table below gives some examples:

    Display Type

    Response Time

    23.6'' Circular Round LCD Display

    0.1 second

    16inch Round Monitor

    6ms

    • Lower response time makes your display react faster.

    • Quick actions make your device easier to use.

    • The display works better overall.

    • Fast response time helps with games, videos, and touch controls.

    If you want your round display to feel smooth and modern, always check the response time. Fast response time makes your device more fun and simple to use. It also saves power because the display does not waste energy on slow updates.

    Durability and Environment

    When you pick an lcd round display, think about how tough it is. Durability helps your display last longer. Environmental resistance lets it work in many places.

    Temperature Range

    Check the temperature range before you choose a display. Some lcd round displays work in very hot or cold places. Industrial models can handle -30°C to +80°C. These are good for outdoor and factory use. Regular displays work from 0°C to 50°C. If you store your device, it can handle -20°C to 60°C.

    Type of Temperature Range

    Temperature Range

    Operating Range

    0°C to 50°C

    Storage Range

    -20°C to 60°C

    Displays that work in extreme heat or cold stay reliable. High heat can hurt the liquid crystals. This can break the display. Cold can make the screen slow. It might show marks or streaks. If you use your device outside, pick a display that handles these changes.

    Temperature Impact

    Description

    High Temperatures

    Liquid crystals can melt and stop working.

    Low Temperatures

    Screen can show ghost images and slow down.

    Operational Limits

    Going past limits can cause streaks and jitter.

    Tip: Match your display’s temperature range to where you use it. This helps your device work well and not break.

    Weatherproofing

    Weatherproofing keeps your lcd round display safe from water and dust. Look for displays with high IP ratings. These ratings show how well the display blocks water and dust. Seals between the cover and case keep moisture out. Touchscreens need special chips to work when wet. Makers use coatings on the PCB to stop water damage.

    Waterproofing Aspect

    Description

    IP Rating

    Shows how well it blocks dust and water.

    Sealing Techniques

    Seals between cover, case, and touchscreen.

    Touchscreen Functionality

    Works even with water drops.

    PCB Waterproofing

    Coating keeps electronics safe from moisture.

    Housing Assembly

    Sealant and vents block water and let air move.

    Additional Measures

    Special compounds, sealed connectors, and drying packs keep moisture out.

    Weatherproofing helps your display survive in tough places. It protects from water, heat, and bumps. Strong designs use hard glass or plastic to stop damage. Seals keep out dirt and water. This makes your display last longer. Some displays use salt waterproofing to help touch work and keep the screen safe.

    • Waterproof TFT LCDs work in tough places.

    • Strong cases and coatings help displays last longer.

    • Sealed connectors and vents keep out water and dust.

    • Displays with these features work safely from -30°C to +80°C.

    Note: Good weatherproofing and temperature control help save power. Your device uses less energy to keep the display working in hard places.
