Upgrade or downgrade of the LCD resolution. Upgrading from CCFL to LED backlight

Upgrading from CCFL to LED backlight:

All the laptops use LCD screens:

LCD screens require a backlight system to operate, there are two backlight systems in use today: CCFL and LED

CCFL - Cold Cathode Fluorescent Light, is an older backlight method, which utilizes a daylight specter fluorescent tube and an inverter which powers it.

LED - is a newer backlighting system which does not use an inverter, and instead of a fluorescent tube it uses a strip of LEDs (Light Emitting Diodes).

So in essence there are two types of laptop screens: LCD-CCFL and LCD-LED. These screens are NOT INTERCHANGEABLE.

Laptop manufacturers tailor their system for a particular LCD screen, so it is impossible to install a CCFL screen into a computer outfitted for an LED screen, and vice-versa.

Currently there is no possible way to upgrade from screen that uses CCFL backlight to LED. LED and CCFL laptop screens are not interchangeable since they use different connectors, as well as power sources. Laptop's motherboard will have to be replaced in order to upgrade the laptop from CCFL backlight type to the LED backlight type.


Upgrade or downgrade of the LCD screen resolution:
In a nutshell - resolution of the replacement screen must be the same as resolution of the screen which is being replaced.
We advise our customers against upgrading or downgrading of the screen resolution. Our company witnessed several cases where as a result of a resolution upgrade customer's video card had ceased to work properly or became completely unresponsive. A video card operates in a similar way to the CPU, the only difference lies in its purpose. Video card is used solely for image processing. Just like CPU, it can be overloaded when connecting to a screen that has a significantly higher capacity, as it will require more processing power. There are exceptions to this rule. There are some customers who have successfully changed their laptop screen resolution while upgrading their screens. It all depends on the brand and capacity of particular video card. Screen manufacturers will sometimes install different resolution screens with the same video card, although, we would strongly recommend against trying this type of an upgrade as there is a chance of damaging video card and the cost of repairs can be as high as replacing an entire motherboard, if the video card is integrated.
