Replacing a damaged LCD monitor is no easy task. LCDs are expensive, and so are their parts or modules. Let’s take a look at a notebook computer LCD, for example. If you go to a service center to have it fixed, they’ll probably give you a hefty sum to pay as service fee, plus it’ll probably take about a week to have your repaired unit shipped back from the manufacturer. What if your notebook computer is your work, your livelihood? All because of a broken LCD monitor…
An LCD display module refers to any piece of hardware or component that comprises the LCD unit as a whole. The basic modules of a standard liquid crystal display device includes the vertical filter film, the glass substrate, the nematic liquid crystals, another glass substrate, the horizontal filter film, and the innermost reflective surface. Other pieces of hardware include battery-powered devices such as the video cable and the inverters. These electronic devices normally require minimal amounts of electric power.
LCD Specifications
You can always purchase a new LCD module from an independent manufacturer and replace the broken part yourself, but only if you know how.
The following are the different LCD specifications:
Resolution: This is the vertical and horizontal size of the screen. Resolution is expressed in pixels. Unlike CRTs, LCDs feature native resolution for the best possible display effect.
Dot pitch: Dot pitch is the distance between two phosphors within the screen area. The closer they’re packed together, the sharper the image will be.
Viewable size: More popularly known as an active display area, viewable size is the size of the LCD screen when measured on the diagonal.
Response time: This is the time required for a pixel to change color or brightness.
Other notable LCD specifications include matrix type, viewing angle, color support, brightness, contrast ratio, aspect ratio and input ports.
