Smartphone LCD Screen for BlackBerry Bold 9700 Buying Guide

Your cellular device is a tool that can help you stay connected to the world around you at home and on the go. If the screen of your smartphone has become cracked, chipped, or otherwise damaged, replacements are available. Here are some things you may wish to know if you are looking to replace LCD screen of your BlackBerry Bold 9700 or any smartphone.

How do LCD screens function?

The LCD screen is an important part of your BlackBerry Bold. Knowing what makes your LCD screen function properly can be helpful in maintaining or fixing it.

  • Liquid Crystal Display - LCD is short for Liquid Crystal Display. This kind of liquid crystal technology can be found in many devices including computers, tablets, and smartphones like the BlackBerry Bold 9700. Liquid crystals are tiny, light-modulating, reflecting parts that help to produce monochromatic and fully saturated images.
  • Lightweight components - Smartphones that utilize LCD technology are able to be lighter and more electronically efficient than older tech that uses LED or gas display systems. LCD takes little electric energy from the power components of your BlackBerry.
  • Blockage of light waves - LCD operates by blocking light instead of creating it. This is part of the reason that it's so efficient. The tiny interior crystals in the display system are paired with transistors that communicate with each other when the light is blocked.
  • Active and passive matrix - An LCD screen can utilize either an active or passive matrix system. The matrix is the way the crystals are organized with their corresponding transistors to transmit data. An active matrix, or TFT (thin-film transistor) matrix, increases color saturation and maximizes luminescence and contrast output.
What are some reasons to replace an LCD screen?

When certain issues develop, you'll know it's time to replace your screen. Also, knowing what to avoid in the future can help you keep your screen working fine after the replacement is installed.

  • Cracks and chips - Cracks and chips are created when your BlackBerry's screen or any other LCD screen experiences impact of some kind. The LCD communication grid must be intact for a screen to operate correctly. If a device's screen has become cracked or chipped, the grid matrix becomes disrupted and the crystals are unable to communicate with their corresponding transistors, causing the screen to glitch.
  • Water damage - Water damage causes electronic components to corrode and rust, thus blocking the light-wave receptors. Some water damage can be fixed with cleaning, but in many cases, a new screen will be needed.
  • Exposure - LCD systems are sensitive. Exposure to impact, high or low temperatures, or chemicals can also damage an LCD screen system.
What do you need to install a replacement LCD screen?

You can find both OEM replacements made by BlackBerry and generic parts that are designed to be compatible with your BlackBerry Bold 9700. You can buy the screen and necessary tools separately choose a kit that includes the screen and the tools needed for installation. These typically include a 5T Torx screwdriver, a prying tool to separate components, and a suction device to lift the old screen.
