15.4" Laptop Screens and LCD Panels

When buying 15.4" laptop screens and LCD panels, the main technical features to bear in mind are the contrast ratio which is important for overall picture quality, the width of the viewing angles and the effect on colour intensity when viewing from the side, as well as the luminosity and reflectiveness of the screen. Screens are available in matte and glossy finishes, so if you are using your laptop in a brightly lit space, the former is advisable.

The profile of replacement laptop screens and LCD (Liquid Crystal Display) panels has changed over the years. Modern backlight technology allows for much slimmer displays, which is convenient if using a multi computer monitor setup, where the gaps between the displays need to be as thin as possible.

The standard screen technology for mass market 15.4 inch laptop screens and LCD panels is TN (Twisted Nematic), which is a liquid gel compressed between two glass panels. These cost less to mass produce and produce a decent performance in terms of contrast ratio and the fast response times required for gaming. However, viewing angles may be slightly restricted, meaning that the brightness and colour of the picture can appear to shift if not viewed straight on. For regular screen usage, this is unlikely to be a problem.

Most non-TN panels use In-Plane switching (IPS) or Plane-Line switching (PLS) panels, which provide a higher quality viewing experience, with the consequent difference in price. Vertical Alignment (VA) screen panels are becoming more and more popular, as this technology works efficiently when transitioning rapidly from light to very dark colours.

If you want excellent overall accuracy and quality, the MacBook Pro 's 15.4 inch, 2880x1800 Retina display is at the top end of the market. It has a very high quality luminosity (brightness), colour range and saturation, and text looks extremely crisp and clear. The viewing angle is excellent and reflections are manageable for a non-matte screen.
