MT Views: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.

  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).
