Frequently Asked Questions

The following FAQ page contains questions and answers to the most frequently asked questions regarding laptop LCD screens. The questions have been divided between the following categories:

Technical Issues

What are the different LCD screen sizes for laptop and tablet PC computers?

Laptop and tablet PC screens range in size from 7.0 inches to 20.1 inches. The size is measured diagonally based on the viewable area of the screen. Size is measured diagonally; see this page for more information.

What is LCD screen resolution? And, what are the different LCD screen resolutions for laptop and tablet PC computers?

Laptop and tablet PC computers come in many different resolutions. Resolution is defined as the number of pixels or small dots that make up an LCD screen. The pixel is the smallest unit that makes up an image. Most screens sold today are TFT active matrix LCD screens. TFT active matrix is a technology in which each pixel has a transistor attached to it to control the backlight shining through it. Each pixel is made up of 3 sub-pixels (red, green and blue) with each having its own transistor. Each of these pixels turns on and off and filters light through colored sub-pixels which results in an image. The more pixels or higher the resolution a screen is the crisper the image. In addition, higher resolution screens allow more of an image to be viewable.

The following table shows the LCD screen resolutions available in laptops and tablet PCs.

Resolution Pixels Aspect Ratio Type of Ratio
SVGA 800 x 600 1.33x Standard
XGA 1024 x 768 1.33x Standard
WXGA 1152 x 768 1.50x Wide
WXGA 1280 x 768 1.66x Wide
WXGA 1280 x 800 1.60x Wide
WSXGA 1280 x 854 1.50x Wide
SXGA 1280 x 960 1.33x Standard
SXGA 1280 x 1024 1.25x Standard
WXGA+ 1440 x 900 1.60x Wide
SXGA+ 1400 x 1050 1.33x Standard
WSXGA+ 1680 x 1050 1.60x Wide
UXGA 1600 x 1200 1.33x Standard
WUXGA 1920 x 1200 1.60x Wide
QXGA 2048 x 1536 1.33x Standard

As can be seen in the table above, LCD screens are considered either standard-aspect or wide-aspect. Wide-aspect ratio screens which have become quite popular recently are LCD screens with a resolution aspect ratio greater than 1.33x (number of horizontal pixels / number of vertical pixels).

What is a backlight? Why does this matter?

Laptop, tablet PC, and netbook screens use a "backlight" to illuminate the liquid crystal display within the screen. There are two kinds of backlight technologies, and they are not interchangeable:

  • CCFL (cold-cathode fluorescent lamp) - an older technology, still very common
  • LED (light-emitting diode) - a newer technology, gaining in popularity especially in netbooks

For more information on laptop screen backlight technology, see this page.

What is the relationship between size and resolution?

Basically, the larger the LCD screen the higher the potential resolution. LCD screens are stated at their maximum resolution which may be adjusted downwards should you need to. Each LCD screen size may come in different maximum resolutions. See the table below for screen size and potential resolution combinations.

Size Available Resolutions Aspect
10.4 x x                       Standard
10.6       x x                 Wide
12.1 x x   x(a)         x         Standard
13.0 x                         Standard
13.3   x                       Standard
14.0       x                   Wide
14.1   x             x   x     Standard
15.0   x             x   x   x Standard
15.2     x     x               Wide
15.4         x   x(b)     x   x   Wide
15.7             x             Standard
16.0             x             Standard
16.1                 x   x     Standard
17.1               x   x   x   Wide


(a) wide-aspect ratio LCD screen.
(b) standard-aspect ratio LCD screen.


Can I upgrade the size, resolution, or backlight of my laptop LCD screen?

Screen size cannot be upgraded.

In rare cases, your laptop resolution may be upgraded, depending your notebook's video card and whether a compatible LCD screen of higher resolution exists. Even then, we generally discourage against upgrading resolutions as it is not easy to determine a compatible LCD screen between resolutions.

Backlight technology (CCFL vs. LED) is not interchangeable, therefore cannot be changed.

Do I need a new laptop LCD screen if I have lines on my screen?

It is possible that you need a new laptop LCD screen. The presence of lines could indicate a problem with the screen, the video cable or the video card.

Are some laptop LCD screens compatible with other LCD screens?

Yes. Laptop LCD screens may be compatible with other laptop LCD screens. Moreover, laptop makers like Dell, HP Compaq, IBM, Toshiba and Sony may source more than one LCD screen (as distinguished by the LCD screen's part number) even from different brand LCD screen manufacturers to install in the same laptop model. There are many variables to take into consideration like various physical constraints, electronic signaling characteristics and power issues.

Do I need a new laptop LCD screen if my LCD screen is dim?

You may or may not need a new LCD screen if the LCD screen is dim. If your LCD screen is dim it may be as a result of either 1) a faulty backlight or 2) a faulty inverter. The backlight is basically the light bulb in the laptop LCD screen which as one would suspect has an average useful life. The inverter, though, is a separate piece from the LCD screen. The inverter essentially 1) takes the DC power which the laptop runs off of and converts it into AC power and 2) steps-up the voltage to light up the cold cathode fluorescent backlight.

We have found that when a laptop LCD screen is dim the majority of the time it is a result of a faulty inverter (especially for HP laptop components). Unfortunately, the best way to determine which is the cause of the dim screen is through process of elimination by trying either a new LCD screen or a new inverter and seeing which solves the problem. We highly recommend you purchase an inverter first as inverters are less expensive than LCD screens. ScreenTek does not carry inverters, however, we would be more than happy to refer you somewhere.

Can I call for Technical Support?

Give us a call or send us an email anytime regarding technical support.

Do you have specs sheets / data sheets for laptop LCD screens?

Products Offered

For what products do you sell LCD screens? Do you sell LCD screens for products other than laptops?

ScreenTek sells LCD screens only for notebook and tablet computers and other industrial uses. We do not sell the following products or LCD screens for the following products: flat panel monitors for desktop computers, CRT monitors for desktop computers, PDAs, cellular telephones or DVD players.

Does ScreenTek sell inverters or video ribbon cables (data cables)?

ScreenTek does not sell inverters or video cables. We specialize exclusively in notebook LCD screens. Because we specialize exclusively in notebook LCD screens it has enabled us to become the preeminent LCD screen supplier in terms of inventory, knowledge and customer service. Should you be looking for an inverter or video cable, give us a call anyway and we will gladly refer you somewhere.

What is the condition of the notebook LCD screens that ScreenTek sells?

ScreenTek sells brand new notebook LCD screens direct from our overseas suppliers in order to ensure the highest quality standards in the market for all brands and model of laptop. ScreenTek also sells other screens like refurbished and pulls for those customers looking for other alternatives.

Be wary of other vendors claiming to have new quality or even refurbished notebook LCD screens as there are very few vendors that can provide this quality of screen. Most laptop screen vendors get their inventory by breaking down used, overstock or "scratch and dent" laptops, and therefore, is difficult to assess the quality of the LCD screen. See below for industry definitions of quality standards.

Term Definition Quality Issues
Backlight Spots Scratches
New Not previously installed in an application. Good None None
New Pull LCD screen that has been removed from a new laptop which has never been used or sold. These new laptops are overstock or "scratch and dent" laptops that are being broken down for parts. Good Potential Potential
Pull or Used Pull LCD screen that has been removed from a previous laptop which may have been used or previously sold. These laptops are being broken down for parts. Uncertain Life Potential Potential
Refurbished Screens that have had the backlight replaced, been repolarized or other video repair to bring quality level close to that of a new screen. Most vendors claiming to have refurbished laptop screens actually do not. Most of these vendors' screensare used and have not undergone a refurbishing process. Sometimes Replaced Generally None Generally None

Do the laptop LCD screens from ScreenTek include the plastics (also known as the display assembly, bezel or screen housing)?

No. The laptop screens from ScreenTek do not include the plastics. There are several reasons for this. The majority of our LCD screens are brand new and direct from our overseas suppliers and manufacturers. Because of this, we are actually purchasing our LCD screens prior to them being installed into their plastic display assemblies by the laptop makers. By purchasing them direct we can better ensure quality to you as they have not been previously handled, used or installed (also see question above). Furthermore, if your LCD screen is damaged your plastic display assembly usually is not damaged. Purchasing a screen in the display assembly usually means paying more for a screen because it has the plastics and/or sacrificing quality as you cannot assess whether the screen has been previously used. Why pay more or sacrifice quality just to have the plastics when more than likely you do not need the plastics.

Should you require or purchase a laptop screen already in the plastic display assembly, please be aware that you are usually purchasing a pulled or used LCD screen (see definitions above) for which quality or useful life cannot be determined.

What screen sizes does ScreenTek sell?

Laptop and tablet PC screens range in size from 7.0 inches to 20.1 inches. The size is measured diagonally based on the viewable area of the screen. Size is measured diagonally; see this page for more information.

What are high-gloss / enhanced brightness laptop LCD screens and what companies manufacturer these screens?

High-gloss / enhanced brightness screens are a term for bright, high-contrast LCD TFT active matrix laptop LCD screens. These types of LCD screens are manufactured by various LCD screen OEMs (Original Equipment Manufacturers). There is not much documentation as this information is proprietary between the LCD screen manufacturers and the laptop makers. However, despite the lack of publicly available documentation, we have noticed that all enhanced brightness screens have a high luster glossy finish. LCD screens with a high luster glossy finish have a different type of polarizer (the film on top of the glass) than common laptop LCD screens.

Enhanced brightness laptop screens include one or both of the following characteristics:

1) High-gloss polarizer
2) Stronger and/or multiple backlights

LCD screens whose brightness is increased solely by a high-gloss polarizer are compatible with non-high-gloss LCD screens, holding all other things equal. However, for those LCD screens with stronger or multiple backlights, compatibility may be constrained by the number of inverters required to power the multiple backlights or the output required to power a stronger backlight.

LCD screen manufacturers that produce enhanced brightness LCD screens for the laptop makers currently include Samsung, Sharp and Toshiba-Matsushita. Laptop makers that currently offer laptop models with enhanced brightness LCD screens are the following:

Why is there more than one price listed for the LCD screen for my model laptop?

Many laptop models come with more than one type of LCD screen. This is most obvious for those laptop models that come with LCD screens of different sizes or resolutions. For example, the Dell Inspiron 5100 may have:

  • a 14.1" XGA (1024 x 768 pixels) display,
  • a 15.0" XGA (1024 x 768 pixels) display,
  • or a 15.0" SXGA+ (1400 x 1050 pixels) display.

Prices of LCD screens commonly vary by size, resolution, backlight, and surface, in addition to other characteristics.

In addition, it is possible that a particular laptop may use two different laptop screens of the same size, resolution, and backlight technology, that are still not compatible with each other. In these cases, the notebook screens will most likely have the same price unless one is in more demand and relatively short supply.

What does shipping add to the price of a new screen from ScreenTek?

It depends on where the screen is going, and how quickly. Shipping a screen within the United States costs $15 for 2-3 Day service, or $25 for Overnight (5-10 Day service is free). Outside of the United States (and to certain U.S. territories), the shipping price depends on your location. If you fall into this category, please use this page to determine the cost for your location.

The price given is to ship one screen. For each additional screen, simply add $3for domestic shipments and $6 for international shipments. For orders of three (3) or more screens, please contact us for a customized shipping quote.
