To determine whether your laptop screen is an LCD (liquid crystal display) or LED (light emitting diode) backlit screen, it is usually important to note that most modern laptop screens use LED as the backlight technology, not just the traditional LCD screen.
The difference here is the backlighting method, not the display technology of the screen itself. However, for a clearer explanation, we can distinguish it this way:
1. Check the technical specifications directly:
- The most direct way is to check the technical specification sheet or user manual of your laptop. These documents usually clearly indicate the type of screen and backlight technology.
2. Use system information tools:
- In Windows systems, you can use the "Device Manager" to view detailed information about the hardware, but it usually does not directly display the screen backlight type. However, you can install some third-party system information software, such as CPU-Z, HWiNFO, etc., which may provide more detailed hardware information, including the screen backlight type.
- For Mac computers, you can view a hardware overview through "About this Mac" > "System Report", but again, the backlight type may not be directly displayed here.
3. Judging by appearance and features (not very accurate, but can be used as a reference):
- LED backlit screens are usually thinner and lighter, and due to the high energy efficiency of LEDs, the battery life may also be relatively long.
- If your laptop screen is bright and colorful, and the power consumption is low, it is likely to be an LED backlit screen.
4. Search online resources:
- Search your laptop model and "screen type" or "backlight technology" on the Internet, you may find relevant forum discussions, user reviews or professional reviews, which usually mention the specific type of screen.
5. Contact the manufacturer or seller:
- If the above methods cannot be determined, you can contact the manufacturer or seller of the laptop, who should be able to provide accurate screen information.
It should be noted that most modern laptop screens use a combination of LCD display technology and LED backlight technology, the so-called "LED backlit LCD screen". Therefore, when you see "LED screen", it actually refers to an LCD screen that uses LED as a backlight source. Pure LCD screens (without LED backlight) are very rare in modern laptops.
