    What Are the Differences Between PCBs Used in LCD and AMOLED Displays?

    LCD (Liquid Crystal Display) and AMOLED (Active Matrix Organic Light Emitting Diode) are two reliable display technologies. These are mostly used in mobile displays. There are some distinguishable properties between the circuit boards used in these two display mechanisms.

    Display Color

    AMOLED PCB enables the display to deliver realistic colours. These circuit boards also superbly control the aspect ratio and contrast. The AMOLED PCB allows displays to be dark.

    In contrast, LCD circuit boards are capable of displaying true life colours. They can’t achieve a completely black display. LCD makes it easier to enjoy viewing in bright conditions.

    Energy Efficient

    AMOLED displays are more energy-efficient than LCD boards in a way. AMOLED displays can separate light pixels. That’s why AMOLED can achieve standard energy efficiency in most mobile displays.

    LCD circuit boards don’t show such effectiveness in smartphone displays.

    Viewing Angle

    LCD circuits provide a higher viewing angle in electronic display appliances. Its highest angle of view is around 180⁰. But, AMOLED can’t deliver such a wide-angle of view.

    LCD vs AMOLED Display Circuit Boards

    LCD vs AMOLED Display Circuit Boards


    AMOLED displays are more expensive compared to LCD circuit boards. The manufacturing process is easier in the case of LCD PCBs since LCD technology was established first.


    AMOLED displays contain flexible, stretchable, and adaptable features. In contrast to this, LCD technology does not support Flex Display PCB, for example, LCD is not used in foldable smartphones.

    Burn-in Effect

    AMOLED displays suffer from burn-in issues. But, LCD circuits are almost free from this precarious issue.

    What Are the Features of USB LCD Display PCB?

    How Do You Control the Quality of a Display PCB?

    Quality control is a vital factor for optimum display PCB manufacturing. You can maintain the top quality of this circuit board by following some measures. Here we show you the factors related to the quality maintenance of display modules. Let’s have a look.

    Component Sourcing

    You need to use durable and excellent components to construct display circuits. Otherwise, it is difficult to maintain higher standards of display in electronic appliances. You must check different features like current ratings, power dissipation,  and thermal conduction capabilities before choosing PCB components.

    Material Selection

    This is another crucial factor in controlling standard display quality. Effective dielectric materials promote the functionality and operating time of display circuits.

    Regular Inspection

    You need to inspect the PCB during design to check its condition. Regular checks promotes the longevity of display circuits.

    PCB Quality Control

    PCB Quality Control

    Reliable Testing

    This is another major part of PCB quality control. You can conduct manual and automated tests to detect faults. The following tests are reliable for display PCB performance checking.

    • Flying probe test
    • In-circuit test
    • Automated Optical Inspection
    • Automated X-ray Inspection
    • Functional tests

    Choose the right testing after considering your production volume and budget.

    Proper Maintenance

    It is important to perform preventive maintenance for display devices. You need to proactively check for temperature changes, moisture, contamination, and etc. while handling Display PCBs.

    Why Do You Need to Consider Temperature Change While Designing a Display PCB?

    Temperature affects PCB performance in various ways. You should control the operating temperature of the Display PCB to achieve maximum output. Improper temperature change is harmful in the maintenance of thermal, electrical, and mechanical properties of PCB materials.

    Display PCB Temperature Control

    Display PCB Temperature Control

    That’s why you need to consider changes in temperature during the design phase. Frequent and unplanned change of thermal states creates  serious complications in signal transmission systems of display circuits. Such as:

    • Improper temperature rise increases current conduction through the circuit board. It causes overheating that significantly reduces the operating life of display modules.
    • Impedance control is a mandatory requirement for achieving standard data propagation. Impedance control improves the integrity of audiovisual signals. Impedance stability is dependent upon temperature change to a certain extent.
    • Excessive heat makes the high-frequency signals vulnerable to electromagnetic interference. Signal quality falls when there is such an interference, then the display will be affected functionally.
    • Dielectric materials lose their efficiency in extreme temperatures. Temperature fluctuations affect dielectric strength and relative permittivity. Then you don’t get sufficient insulation during the current flow that is needed for viewing video content.
    • Standard temperature rise is necessary for high current Display PCB. It’s also a requirement in multilayer designs of display circuit boards.

    Hence, you see now that ensuring correct temperatures is needed to optimize Display PCB performance.

    How Can You Repair a LED Display PCB?

    LED display PCBs can suffer from some technical problems. When this happens, you need to repair the PCB. If the damage goes beyond repair, you should replace them to maintain the integrity of the device.

    To repair a LED display circuit board, you have to first determine its problem. A short circuit is a common issue. You need to detect resistance, voltage, and circuit connections through a multimeter.

    If you detect a short connection, resolve the issue immediately to save other components from burning.

    Display Printed Circuit Board Repairing

    Display Printed Circuit Board Repairing

    If you find a defective or damaged wire or component, remove them and solder quickly. Then, clean that portion on the surface and cover it with copper tape. Next, solder the connections.

    After that, restore the through-holes of the Display circuit board. The remaining task is to place a new component in place, then and solder properly. If you face any difficulty, contact a skilled technician to deal with this issue.
