Characteristics of the screen are determined by three important parameters: size, resolution, and connector type. Show You absolutely need to know the size, resolution, and connector type. The same laptop model may use different
models of screens that differ in size, resolution, and connector type. Please make sure that your old screen is the same size, resolution, and connector type as the one you are buying to replace it with. We would like to point out that notebook manufacturers have been slow to disclose this information, even in cases where they post it on their website - it may not be accurate enough (as we noted earlier), so the most reliable way to select the right screen - is to know the size, resolution and connector type of the old, or just the model number. One exception to the model rule are computers from Dell, screens for those are best identified by the Service Tag Number. 1. How do I
know the screen resolution? Resolution - is the maximum number of pixels of your screen. Each standard resolution has a designation, the following is a list of some used in laptops: XGA 1024x768 SXGA 1280x1024 SXGA + 1400x1050 UXGA 1600x1200 QXGA 2048x1536 WXGA 1280x720; 1280x768; 1280x800; 1366x768 WXGA + 1440x900 WSXGA + 1680x1050, 1680x945 WUXGA 1920x1200, 1920x1080 "W" - means wide-screen aspect ratio of 16:10 or 16:9. If your screen resolution is 1366 x 768, it means that the screen has 1366 pixels horizontally and 768 vertically. A few ways to find out the screen resolution: 2. How to measure the size of a laptop screen? Screen size is measured in inches diagonally. 3. Make sure that you new screen has the same Connector Type as your old one! LCD screen connectors vary by size and pin count. While some laptops use very unique and proprietary connectors the majority of screens use two most common connectors: 30-pin connector is the most common style in use today. It can support non-touch screens up to a resolution of 3,840 x 2160. 40-pin connector is used in modern touch and high resolution screens, but it was also used in older LVDS screens from 2010-2015. Backlight type. There are used to be two different types of backlight: CCFL (discharge lamps) and LED (Light Emitting Diods). These two types of backlight are incompatible. In the past it was important to know backlight type of your screen. However if your laptop was manufactured in 2011 or after it is almost certain that you have a screen with LED backlight. CCFL technology is now obsolete. Screens with CCFL backlight required high voltage inverter to light up those ancient CCFL bulbs. Some even had two bulbs thus two inverter where needed. LED backlight became widely used starting in the early 2010s. It consists of Light Emitting Diodes. So the screen does not need the inverter and typically has only one connector for a video cable. LED screens do not require inverters. What type of laptop display backlight requires an inverter?If you do have a fluorescent lamp, then you're going to need an inverter that is used to be able to convert from the DC that's inside of your laptop to the higher voltage AC that's used by these fluorescent lamps.
Which of the following display types does not use an inverter?As LED [Light Emitting Diode] screens don't need the high voltages as of a cathode lamp, and LEDs require a DC voltage, the LED screens do not use the inverter. So, LED SCREENS DO NOT COME OR USE POWER INVERTERS.
Does LCD require inverter?what is it for? An "inverter" is a power supply that converts DC to AC. A LCD panel should only need an inverter if it had CCFL lamps for its backlight.
How is a laptop backlight related to the inverter?The inverter is one of the key parts within a display; it allows for the laptop's display to be lit by providing power to the screen's backlight. As you know from our previous blog posts, there are two types of LCD screens: LED and CCFL. LED and CCFL are merely the backlight types – everything else is just the same.
