With the rapid growth and prosperity of commercial development, square framed displays, as a form of terminal display media, have attracted increasing attention from advertisers. However, despite nearly 20 years of development, many technical details of square framed displays remain unresolved. One of these issues is the occurrence of display blemishes or dark spots.
The dark spot phenomenon in square framed displays has existed for a long time and has almost become an overlooked industry defect. Although some component manufacturers have continuously improved their processes and made efforts to address this issue, the results have been limited.
Head Sun recommends the following measures to prevent dark spot formation on square framed displays:
Proper Installation and Use
Professional Installation:
When installing a square framed display, ensure that it is installed correctly by qualified professionals in accordance with the product instructions.
Avoid scratching or applying pressure to the screen surface during installation.
Avoid External Pressure:
During use, avoid pressing the screen surface of the square framed display with fingers or hard objects to prevent damage to the LCD panel.
Special care should be taken to prevent heavy objects from pressing against the screen, as uneven pressure on the internal liquid crystal molecules may result in dark spots.
Operating Environment:
Select an appropriate operating environment and avoid using the square framed display under extreme temperature or humidity conditions.
Avoid prolonged exposure of the screen to direct sunlight, as this can accelerate panel aging.
Regular Cleaning and Maintenance
Routine Cleaning:
Gently wipe the surface of the square framed display with a soft, dry cloth or a dedicated screen-cleaning cloth to remove dust and stains.
Avoid using chemical cleaners or abrasive/particle-containing fabrics, as they may damage the screen surface.
Connection Inspection:
Regularly check that the connections between the square framed display, the power supply, and signal cables are secure.
If loose connections or cable aging are detected, replace the cables or reconnect them promptly.
Ensure Power and Signal Stability
Stable Power Supply:
Ensure that the power source connected to the square framed display is stable and reliable, and avoid excessive voltage fluctuations that may damage the screen.
During thunderstorms, it is recommended to turn off the power to protect the display from lightning-related damage.
Signal Stability:
Ensure that the square display screen receives a stable and reliable signal to prevent abnormal display performance caused by signal instability.
If poor signal reception is observed, promptly inspect the signal cables or adjust the signal source.
Prevent Display Aging
Reasonable Usage Duration:
Avoid continuous long-term operation of the square framed display to reduce the rate of panel aging.
When the display is not in use, turn off the power promptly to extend its service life.
Avoid Excessive Exposure:
Prevent the screen from being exposed to strong light for prolonged periods to minimize aging and color fading.
For indoor applications, curtains or blinds can be installed to reduce direct sunlight exposure.
