Monitor Panels Types is one of the most frequently asked questions, today we're going to covered it but before we need to mention the progress.
In the first computers and until the 70s, they did not have a monitor connected since the data output was done on other media.
From the 70s, the first CRT monitors (cathode ray tubes) designed specifically for text and monochrome began to appear. A few years later the CRTs appeared in color, along with the first graphics cards.
Currently, it is almost impossible to find a CRT monitor since the TFT type has filled the market since the 2000s, they have evolved and improved as time has passed until we find the current and extensive range that they offer us today in day.
In this guide we will see in-depth the differences between the different Monitor Panels Types that we can find in the current monitors, we will see which one can best adapt to the daily needs of each one.
Monitor Panels Types
Currently we can find several Monitor Panels Types with different characteristics, each according to some of the most common situations in our daily life, whether leisure or work, so we can distinguish between:
- TFT-LCDor liquid crystal display of thin film transistors, these are a type of active matrix LCD that uses a thin film transistor (TFT) to improve LCD quality. Within the TFT-LCD type we find 3 main variants:
- TNTwisted Nematic
- VAVertical Alignment
- IPSIn-Plane Switching
- PLASMA practically in disuse, the plasma panels consist of many tiny cells between two glass panels that contain gas (neon, argon and xenon), these are electrically converted into plasma which causes them to emit light.
- OLEDor Organic LED, is formed by a film of organic components and these react to an electrical stimulation, because of this they are able to generate and emit light by themselves. They degrade over time.
- QLEDor quantum dot LEDs, are capable of turning on each independent pixel, are cheaper and more durable than OLEDs.
Features to consider
Each Monitor Panels Types differs from others in certain characteristics, we have to take into account some to choose the ideal Monitor Panels Types in our daily task. Thus we can differentiate:
- Response time: It is the time it takes for a pixel to change color.
- Refresh Rate: The number of times the image is updated for every second.
- Brightness: It is the amount of light that the panel can emit.
- Contrast: It is the relationship between the darkest and brightest intensity.
- Color space: It is the amount of colors that it is capable of representing.
- Viewing angle: It is the maximum angle at which we can look at the panel being displaced from the center, without losing quality in the image.
- Aspect Ratio: It is determined by considering the relationship between horizontal and vertical resolution. They can be among others:
- 4: 3(square monitors) Normally up to 20 ”, they have currently disappeared on home monitors.
- 16:10(widescreen, for example, 1920×1200 or 2560×1600) This type is currently not very common.
- 16: 9(widescreen but less wide, 1920×1080 or 2560×1440) It is the most used for TVs and monitors. It is currently part of the standard.
There are some technologies that together with the graphics card will help us, especially in games, to gain quality. The graphics chip maker AMD has FreeSync technology, which is its implementation of VESA Adaptive Sync technology, NVidia has G-SYNC that requires a dedicated module which makes it a bit more expensive.
Recently NVidia has released this technology and allows use on monitors compatible with Adaptive Sync / FreeSync without the need for these modules.
What they do is synchronize the variable Hertz rate of a monitor with the FPS rate generated by the graph, synchronizing the images and avoiding annoying blurring or tearing of images, this technology would be very useful in fast games such as FPS, sports or racing .
We will see how an appropriate mix in the values of these characteristics will help us decide on the type of panel ideal for us.
Thanks to the color spaces we know how many colors we can represent on the monitor panels. A color space is a specific organization of colors in an image or video. There are physical representations, such as Pantone or mathematically structured, based on RGB as we will see here, sRGB or Adobe RGB , these are called absolute color spaces.
The colors can be created on monitors with RGB-based color spaces, using primary colors, red, green and blue (Red, Green, Blue) and assigning each color to a three-dimensional axis X, Y and Z.
Since 2006, the density of RGB is usually 24 bits, 8 bits per color, this can represent 16.7 million colors (256 * 256 * 256), some implement 16 bits per color, a total of 48 bits. This is useful when the colors are very similar, since, within the same range of colors, we can represent many more.
