Many consumers never even think about purchasing a laptop screen or LCD panel because, normally, they come included when a laptop is purchased. Having a greater understanding of the important features to evaluate when purchasing laptop screens and LCD panels helps to ensure that the consumer is going to get a great product for a low price. If the consumer has never purchased a laptop screen or an LCD panel before, this may seem like an intimidating task, but with the right research and just enough knowledge, it is no problem at all. Laptop screens and LCD panels can be purchased at a variety of places, such as electronics shops, computer repair shops, on the Internet, and on the online auction website, eBay. Evaluating specific factors that need to be considered before purchasing a laptop screen or an LCD panel include: price, size, pixel response rate, resolution, and extra features.
Size is the first, and most important, factor that needs to be discussed. Normally, the consumer has a general idea regarding the size of the LCD screen that he or she wants to purchase. Typical LCD screen sizes vary anywhere between 38 cm to 76 cm. While most people think that bigger is always better, that is not always true when it comes to purchasing laptop screens and LCD panels. The size of the desk space needs to be taken into consideration. Also, the trend for laptops are changing and smaller is now the more valued size. The trend is not following suit for all users, however. Laptops are getting smaller for people who are constantly travelling with them. As for gamers, who primarily use their computers at home, screens are typically larger.
LCD has revamped image quality, and larger screens still produce a great quality image. Although resolution seldom goes past 1080p no matter the size of the screen, it is possible that the image quality can be compromised. It is recommended that a buyer visit an electronics shop to physically see the screen size and decide which is perfect for its intended use. Below is a table that is made of laptop screen sizes, and the resolution that is generally associated with it.
Possible LCD Sizes (cm)
30.48, 33.78, 35.56
39.1,, 35.8, 33.7, 30.74
35.56, 38.1, 39.87
30.74, 35.56, 38.1
35.56, 38.1, 40.64
The viewable megapixels provide a buyer with an idea of how much can be seen on the screen. The viewable megapixels vary from .48 to 1.92. Ratio screens are bigger than widescreens with a ratio of 16:9.. Widescreen is the new trend among laptop screens and LCD panels. Fortunately, because of this ongoing trend, widescreens are now becoming less expensive.
Resolution is defined as the amount of pixels that a monitor can display, horizontally and vertically. The higher the resolution, the more information can be displayed across the screen. Simply put, the higher the resolution, the greater the picture quality. For example, a screen with a resolution of 1920x1080 displays 1,920 pixels across the width of the screen and 1,080 pixels from top to bottom. Most monitors with a resolution of 1920x1080 are considered full high-definition monitors, also known at 1080p. 1080p is recommended for watching high-definition films. In order to have good picture quality, 1080p is recommended, even if it means the size of the screen may have to be minimised. Larger screens, 76 cm and above, can display a resolution of 2560x1600, ideal for viewing highly detailed images or multiple images. For productivity purposes, higher resolution means easier multi-tasking. Higher resolution is better for sharper pictures and films.
Pixel Response Rate
Depending on the buyer's prior knowledge, he or she may not even know what pixel response rate is. The pixel response rate, measured in milliseconds, is the amount of time it takes for a pixel to change from black to white or to transition from one shade of grey to a different shade. Some people believe the measurement of transition from one shade of grey to a different shade is pointless. A faster pixel response rate is better. If the response rate is not fast enough, the display pixels cannot keep up with the information sent from the graphics card, resulting in ghosting, or digital white noise. Most users do not notice the insignificant difference between 5 milliseconds and 7 or 12 milliseconds; although, gamers may notice, and it is recommended that they purchase a laptop screen or LCD panel with a pixel response rate anywhere from 2 to 5 milliseconds. The faster the pixel response rate for gamers, the less likely it is that ghosting or digital white noise is going to appear.
In addition to the primary factors of size, resolution, and pixel response rate that need to be evaluated before purchasing a laptop screen or LCD panel, other panel specs should also be considered. Panel specs for laptop screens and LCD panels include response time, refresh rate, contrast ratio, viewing angle, brightness, LED backlighting, and gloss or matte. Most monitor response times are around 5 milliseconds, which is fast enough for most consumers. It is recommended for serious gamers to purchase a faster response time. The refresh rate is a measure of how many times the display can update the picture in a second. The refresh rate is measured in hertz. The next panel spec that can be evaluated is the contrast ratio. The contrast ratio is a measurement of the monitor's darkest black to its whitest white. The dynamic contrast is less useful to consumers, and the contrast ratio should be evaluated instead.
The viewing angle measures the angle at which the monitor can be viewed in terms of degrees. It is beneficial to understand the viewing angle when considering where the laptop screen or LCD panel is going to be placed. For example, if the LCD panel is going to be hanging on the wall, the viewing angle needs to be taken into consideration to calculate how far back the viewer needs to be seated. The brightness is measured in candelas and tests how much light a monitor can emit. LED backlighting is simply an LCD monitor with LED backlighting. Finally, the last panel spec is gloss or matte. Deciding between gloss or matte depends on the environment in which the laptop screen or LCD panel is going to be. Matte screens are recommended under challenging lighting conditions and tend to appear more dull. However, glossy screens are more vibrant, but readily reflect light.
How to Buy Laptop Screens and LCD Panels on eBay
After a buyer has visualised screen sizes and evaluated specs for a laptop screen and LCD panel, the shopping can begin. eBay offers thousands of options when it comes to purchasing laptop screens and LCD panels. A buyer can begin the purchasing process by simply typing keywords into the search box. The search box is located at the top of every eBay page. For example, a buyer can type in "15.4-inch laptop screen&" and all of the products appear in the search results.
Evaluating the Seller
To put the buyer at ease when purchasing a laptop screen or LCD panel, seller feedback is available. The information that is needed to evaluate the seller is the seller's eBay user ID, seller's feedback score, positive feedback percentage, and detailed feedback. Seller feedback consists of ratings and comments from previous buyers and their interactions with the seller over the last 12 months. For example, if the seller has multiple interactions and positive comments and feedback versus a seller who does not have any feedback, it is recommended to purchase from the seller with more positive experiences. In addition to reviewing the seller's feedback, another way to ensure the buyer gets the product he or she is expecting is to thoroughly read through the product listing.
In order for a buyer to purchase a great product for a low price when it comes to purchasing laptop screens and LCD panels, he or she needs to complete their research. The first question a buyer needs to ask himself is: what is the most important factor? For example, it could be screen size or it could be picture quality. If a buyer is just trying to purchase a laptop screen and LCD panel and get the most for his money, then he may have to make some adjustments. For example, he may have wanted to buy a larger screen, and then once he realised the picture quality is not as good, then it is recommended for him to purchase a smaller screen with a higher resolution. The most important factors to consider when purchasing a laptop screen or LCD panel include: size, resolution, pixel response rate, and additional panel specs. Luckily, eBay provides a wide variety of laptop screens and LCD panels in order to accommodate every buyer's needs.
