Introduction: Interactive flat panel displays (IFPDs) are becoming increasingly popular in classrooms, offices, and other environments. However, some users may notice an issue where certain areas of the screen appear darker or even black. In this blog post, we’ll explore why this happens, and more importantly, how to fix it.
Problem Description:
You may have noticed that your interactive flat panel display is not working properly. Some areas of the screen appear unusually dark, with patches that are darker than others or even black. This issue can be frustrating, but understanding the cause and knowing how to resolve it can help you get back to using your display without further interruption.
What Causes the Dark Areas?
The main reason behind this problem is often related to the LED backlight strip inside the display. Here’s a breakdown of what could be going wrong:
- Loose or damaged LED backlight strips: The backlight strips are crucial for illuminating the LCD panel. If these strips become loose or damaged, certain areas of the screen may not receive sufficient light, resulting in dark spots or shadowy patches.
How to Fix the Issue?
There are two primary solutions to this problem:
- Replace the LCD panel:
- This is often the most effective solution. If the backlight strips are faulty or damaged beyond repair, the easiest and most reliable fix is to replace the entire LCD panel. At DS Tech, we understand the importance of minimizing downtime for our customers, so we provide a new LCD panel replacement during the 2-year warranty period.
- The process is straightforward: simply remove the back cover of the panel and replace the old LCD panel with a new one. This solution is not only efficient but also cost-effective, allowing customers to resolve the issue quickly and easily without needing to worry about technical difficulties.
2. Replace the backlight LED strip:
- Another solution is to replace the individual LED backlight strips. Manufacturers often provide these strips as replacement parts. However, this process requires a distributor or reseller to carefully disassemble the unit, from breaking down touch sensor, front panel, tempered glass, LCD panel to the led strips, then replace the faulty backlight strips, and reassemble the device.
- While this option may appear less expensive from a manufacturer’s perspective, it’s complex and high-risk for resellers and distributors. If done incorrectly, this could result in additional damage to the LCD panel, making the issue even worse. It’s also time-consuming and labor-intensive.

Choosing the Right Supplier:
When selecting an IFPD product and supplier, it’s essential to consider not just the price but also the level of after-sales support. Here’s what to look for:
- Does the supplier offer quick and efficient solutions to technical problems?
- Can they provide comprehensive support throughout the warranty period?
- Are they transparent about the costs involved in after-sales service?
When comparing prices, remember that after-sales costs can often outweigh the initial product cost. Choose a supplier who offers a complete package that supports you throughout the life of the product.
