How a flat panel display works
A flat panel display is composed of the display matrix and the backlighting. These two concepts are why viewing angle and TV size are important considerations when wall mounting a TV when looking for the greatest and clearest picture.
The following infographic explains how everything works.
How a flat panel display works can be a very abstract thought. However, in this blog post, you’ll learn a little more than the basics.
So, here is the answer:
A flat panel display is composed of two main components, the display matrix, and the backlighting.
These two are necessary to show a picture on the screen.
Here is the flat panel display infographic
The display matrix
The display matrix is composed of:- Horizontal polarizer
- Vertical Polarizer
Front and rear polarizers for light that oscillates
Light waves can oscillate on more than one axis. The light that is forced to oscillate on only one axis is called polarized light.A microgrid is made with the Polarized Film
The polarized film is made by stretching a plastic-like material to lengthen its fibers, then dipping the material in iodine to further expand and organize the material’s fibers into a grid of darkened parallel lines that are invisible to the human eye.Twisted liquid crystal
Liquid crystal is a substance in a state between liquid and solid, but that exhibits the properties of both. The liquid crystals in an LCD are naturally twisted in form.Front and rear electrodes
When the polarized light passes through the liquid crystal, it naturally follows the twisting path. Passing an electric current between the front and the rear electrodes causing individual crystals to untwist according to the voltage level. Altering the angle of the light waves. (“And therefore their ability to pass through the front polarizer’) controls the intensity of the light to the viewer.RGB color mask
Every pixel on your screen consists of three subpixels: Red, green, and blue Every sub-pixel has its corresponding transistors on the front and rear electrodes. The transistors are called: “Thin Film Transistor [TFT]” Because they are printed on a thin film for integration into the Display Matrix Sandwich.Coloring pixels by mixing colors
By controlling the intensity of the light to each sub-pixel, the human eye perceives one unified pixel of color just the same way as mixing paints on an artist’s palette. Pixels and their sub-pixels are so small that the human eye blends them as one image.The backlighting composition
The backlighting is composed of:- Monitor frame
- Reflector
- Light guide
- LED strip
- Diffuser Film
- Prism film
