Today, we’ll look at what an LCD is, its history, and the LCD buyback process.
What is an LCD?
A liquid crystal display, or LCD, is flat panel display commonly used in computers, TVs, and smartphones.
History of the LCD
Although popularized in the late 20th and early 21st century, the LCD was invented in 1964 at RCA Laboratories in Princeton, NJ.
Here’s a look at key milestones that gave rise to LCD’s popularity today.
- 1970: LCD experiences first commercial success with advent of twisted-nematic mode of operation. LCDs were used in portable products with small displays like digital watches and pocket calculators.
- 1988: Sharp Corporation creates a 14” active-matrix, full-color, full-motion display using a thin-film-transistor array. After this, Japan launched a full-scale LCD industry where large displays were supplied to personal computers first, then television monitors.
- Mid 1990s: LCD industry moved to Korea and Taiwan.
- 2007: Sales of LCD TVs surpassed CRT TVs worldwide
LCD vs. CRT
Today, LCD technology has largely replaced cathode ray tube (CRT) technology.
Remember the bulky computer monitors and televisions? Those used CRT technology and were so large because those monitors housed an actual tube which projected the display.
CRT works by firing electrons from the back of the tube to the phosphors toward the front of the display. The firing is created by magnetic charges. When the electrons hit the phosphors, they light up and project an image on the screen.
CRT uses the RGB field and is known for its vibrant color. Although this technology is still used today in certain industries due to its color quality, LCD technology continues to improve and closely match the quality of CRT displays.
How an LCD Works
Unlike its CRT predecessor, LCDs use a polarized backlight that provides light to individual pixels on a rectangular grid. Each pixel has a RGB sub-pixel that can be turned on or off. This creates millions of possible color combinations by adjusting individual levels of light. When all sub-pixels are off, the display will appear black. When all sub-pixels are on at 100% saturation, the display appears white.
The liquid crystals are composed of a part liquid, part solid substance that can be twisted using electrical voltage. Modern LCDs use an active matrix, which are more efficient and responsive than passive-matrix displays. Passive matrices controlled individual pixels by sending a charge to their row and column. These displays would often appear blurry during fast-moving sequences since a limited number of charges could be sent per second.
Is a Damaged Screen Still Valuable?
Most devices have two screens—the outer glass cover protects the inner screen, which is the LCD. For example, take a smartphone with a cracked screen. If the phone’s display still lights without error and functions normally, the front glass cover is most likely damaged. If there are spots, lines, or the display doesn’t light properly, the LCD is most likely damaged.
As you may have guessed, the LCD is the more expensive part any screen replacement. It’s important to note that the digitizer, which handles touch screen functionality, is a common associated repair. This is due to the fact that it is also housed behind the glass cover.
Even if the glass cover is cracked, a good LCD is still valuable—there can even be value in an LCD that functions but is damaged.
What is LCD Buyback?
Generally, LCD buyback is a simple process. Repair depots purchase cracked and damaged screens to refurbish. Typically, the company will inspect and grade the device. The grade will translate to a set cash value. You then have the option to accept or reject the offer.
