Summary of popular laptop screens today

Types of laptop screens What types are currently applied by laptop manufacturers? We invite you to read our article below to know more.

1. LCD screen

LCD (Liquid crystal display), also known as liquid crystal display, is a display device composed of cells (pixels) containing liquid crystals that are capable of changing the polarization of light and thus changing the transmitted light intensity when combined with polarizing filters.

LCD screen technology is a technology used quite commonly on many electronic devices today with the advantage of low cost. Compared to the screen using the image (CRT) of the 70s of the last century, LCD is considered a remarkable technology, bringing more convenience and benefits. However, the color density is not good when used outside sunlight and the viewing angle is narrow, the screen quality degrades over time, now LCD screens have become obsolete and are gradually being replaced by new and more advanced technologies.

LCD screen structure consists of (1) – natural light filter layer, (2, 4) – 2 layers of glass with ITO electrodes, (3) – clamping the liquid crystal layer in the middle, (5) – a layer horizontal polarizing filter, (6) – mirror reflects light back to the viewer.

Advantages:

– Slim and lightweight flat design.

– Realistic and sharp light image.

– Energy saving, no harm to eyes.

Defect:

– Poor outdoor visibility, narrow viewing angle

– Screen quality will decrease after 1 time use

2. IPS screen – Types of laptop screens

IPS screen technology, which stands for In-Plane Switching, is a variant of the LCD screen used on high-end technology devices with good color quality and wider viewing angles than conventional monitors. ordinary LCD screen.

IPS displays include typical LCD components, but the difference is that the liquid crystal layers are now horizontally aligned (this is where the phrase “In Plane”) comes from. with 2 layers of polarized glass on top and bottom instead of perpendicular.

This change reduces the amount of scattered light, providing wide viewing angles and good color reproduction. IPS monitors display images with a wider color gamut, commonly used in high-end devices, well suited for graphic design that requires a high level of display quality, in addition, IPS monitors also provide offers a viewing angle of up to 178 degrees from the horizontal, which means that users don’t have to sit directly to experience the full quality of the image.

Advantages:

– Brightness, contrast is what IPS screen technology is worth to be proud of. That is also one of the reasons why the big “Apple” has chosen this screen technology on its high-end product lines such as iPhone, iPad, most recently iPhone 6, iPhone 6 Plus and iPad Air. 2.

– The liquid crystals are arranged in an advanced method, so the color reproduction becomes more accurate and true than the screen.

When viewed at a narrow angle, the details on the IPS screen are not changed too much.

Defect:

– Thicker than AMOLED screens, which is also easy to explain because the structure of AMOLED screens is much simpler than LCD liquid crystal screens.

– AMOLED screens can withstand mechanical impact better than IPS.

– IPS panels consume more power than AMOLED screens.

3. OLED/AMOLED Display

OLED is a variation of LED technology for TVs, phones, and cameras…

The advantages of OLED technology are higher image quality, less power loss and faster response speed.

OLED is the English abbreviation of the phrase Organic Light-Emitting Diode (which can be translated as organic light-emitting diode). The “organic” part here refers to the carbon film inside the display panel. OLEDs emit their own light when an electric current is passed, while LCD panels must have an external light source, such as the display’s backlight.

Because Samsung is the first to develop this technology and they call it AMOLED types of laptop screensand most screens with OLED technology are manufactured by Samsung, so we can also call it AMOLED screens.

Advantages:

– Image quality, high brightness, fast response speed

– Wide viewing angle

– Less power consumption

Defect:

– The production cost of AMOLED screen is high compared to conventional LED-LCD screen

– Monitor performance degrades over time.

4. Retina Display

Retina display technology is used on most models laptop Macbook pro is currently being used by Apple in 2012 with a fairly high resolution of up to 2560×1600 pixels reaching 232.22 on the 13-inch macbook pro line and 2880×1800 pixels reaching 226.42 average pixels on the line. Macbook pro 15.4 inch.

Advantages of Retin screens of all types of laptop screens:

– Transmit and display quality, vivid, smooth images and extremely perfect and sharp colors

– Wider viewing angle, ensuring image quality when you view at multiple angles.

Defect:

– Retina display is quite thick with 3-layer structure (backlight layer, display layer and touch layer)

– The screen has a backlit layer, so it consumes a lot of energy.

– This is a proprietary screen, so it has not been adapted to many technology applications.

5. CCFL monitors – Types of laptop screens

The CCFL screen, which stands for Cold Cathode Fluorescent Lamp, still uses LCD screen technology, but instead of using LED bulbs, CCFL uses neon bulbs to make the screen backlight.

CCFL screens are quite hot when used, consume more power than led screens and have less durability, currently CCFL screens have been discontinued because they reveal too many weaknesses compared to other screen technologies. new life today.

6. TN screen (Twisted Nematic)

TN (Twisted Nematic) screen is a crystal screen structure that appeared on the market a long time ago. With low production costs, TN screens used to be very popular on many electronic devices such as phones, laptops, even televisions.
