Learn laptop screen technologies

When buying a laptop, in addition to configuration and design issues, the screen is also the part that many consumers consider, what technologies they have, what are the advantages and disadvantages, let’s also take a look at the following points. Laptop screen technology is popular in the market.

Retina

Retina is essentially a term created by Apple in large part to apply advertising and marketing rather than the new concept of a type of display. Retina specifically is an IPS-LCD display with a pixel density high enough that the naked eye does not recognize every single pixel under normal conditions. Accordingly, macbooks usually have a pixel density of 230 ppi or more.

According to Apple calculations, the pixel density on the devices is calculated differently based on the screen size to give the appropriate resolution. The advantage of the Retina screen is that the images are displayed smooth and sharp , while the color is almost perfect 99% of the standard color range is closest to reality. The only downside that can be said about this monitor is that it is quite expensive to be able to own it.

TruBrite® TFT LED Backlit

TruBrite® is a display brand from Toshiba for advertising and marketing. This technology helps to absorb most of the light from outside hitting the screen, increasing the screen’s anti-glare, contrast, color accuracy and viewing angles .

In the past, screen panels often did not have a high degree of smoothness, so the outside light entering the screen was often reflected in many directions, causing the opposite reflection that users called glare, this disadvantage is wrong. chromatic aberration, reduced contrast and eye strain.

To overcome this, the manufacturer creates a screen with a smoother background, thereby overcoming most of the above disadvantages. And this technique was adopted by Toshiba but was taken under the name TruBrite® to increase the level of product branding. These technologies are similar to those of Sony XBRITE™, HP Compaq BrightView, Acer ComfyView, etc.

Splendid Video Intelligent

Splendid Video Intelligent is a software technology created by Asus applied to its laptop products. The function helps to change the brightness, contrast, sharpness, and vibrant colors of the image to suit each user’s purpose.

Splendid Video Intelligent will calculate for the image processing chip to fine-tune the basic parameters to suit the needs of the user. Not only reproduces clarity when displayed at low resolution, but also reduces blur to provide a more natural and bright image space.

LED Backlit

Backlit LED technology is applied to liquid crystal display products. Specifically, liquid crystal displays must be backlit to display colors and images.

In the past, people used fluorescent lamps for lighting, but there were many disadvantages, from which LED technology was applied. LED technology makes the screen thinner, less heat , reduced power consumption, better performance , reduced production costs and environmental protection.

Currently, LED Backlit screens are used in most of today’s laptop devices.

The disadvantage of this screen is that usually, if manufacturers do not apply any technology, ie pure liquid crystal screen, the light produced by LED screen carries a large amount of blue light, which affects quite a lot to the eyes.

Active Matrix TFT Color LCD

This screen technology is composed of 3 elements: color TFT, active matrix and LCD. Technically, this is a TFT panel liquid crystal display with RGB pixel technology, the pixels in the screen will be adjusted separately, thereby providing better color and brightness expression through often. From there, the ability to express accurate colors and higher brightness.

Acer CineCrystal LED Backlight

CineCrystal is the liquid crystal display technology Acer calls its name on its laptop devices. This display is a liquid crystal mirror display that uses LED backlight technology.

Mirror screens tend to have better contrast and color reproduction rates than matte screens, making them suitable for multimedia uses such as photo and movie presentations. The main disadvantage is the reflection and glare caused by the glossy coating when using the machine in a brightly lit room or in the sun.

Triluminos Display

Triluminos Display is Sony’s unique backlight technology that enables a wide array of colors to be created through better color filtering, giving viewers rich and natural colors . To do this, Sony used quantum dots.

Specifically, Sony’s Triluminos technology will take advantage of uncoated background LEDs housed in a glass tube filled with red and green quantum dots. These two types of dots will absorb part of the blue light from the backlight and then emit it as pure red and green. With this method, the light that passes through the red filter will take on the correct red color, similarly for the rest of the colors.

As a result we get more accurate color reproduction, better images than using conventional LEDs.

Triluminos technology will make the screen on Sony laptops more vibrant, for wider viewing angles and more realistic colors. Display colors that are difficult to reproduce accurately such as red, green, blue, etc.

HD BrightView LED Backlit

Is the name that HP calls its laptop screens. HD BrightView LED Backlit is actually a liquid crystal mirror screen using LED backlight with HD resolution . The mirror screen helps to increase contrast, brightness, definition, has more depth , is difficult to stain and is easy to clean, clean, … compared to the old generation screen. There are also advantages such as low cost and energy saving.

The downside of the BrightView LED Backlit screen is its poor anti-glare ability, which is quite uncomfortable to use in outdoor conditions.

HD WLED TrueLife

WLED TrueLife screen technology is a combination of two components WLED and TrueLife. WLED (white LED) is a technology that uses white LED backlighting to give a wider and brighter color range . TrueLife is Dell’s commercialized trademark for its products. TrueLife is a mirror screen technology similar to TruBrite, BrightView, CineCrystal…

TrueLife has 10% higher contrast than similar screens, produces clearer and more colorful images, absorbs most of the light in the outside environment, and has a wider viewing angle than your screen. traditional notebooks.

The disadvantage of the screen is that it has poor anti-glare ability, used in outdoor conditions can be uncomfortable glare.

Above are some laptop screen technologies available on the market. Hope the article will help you more in choosing a laptop for yourself and your loved ones.
