Introduction
Most people confuse a digitizer with an LCD. LCD means Liquid Crystal Display. The LCD is a screen that that displays the final image. The Digitizer does the complex work of converting the analog signals into digitally recognizable images. In the current world of smartphones all activities and instructions are given to the phone via touch or swipe. The digitizer stands above the LCD display screen and converts these touch signals into signals that the phone reinterprets. It is also known as LCD digitizer.
Even though the digitizer is a separate component from the LCD, the two are fused together with an optical adhesive and they stay together. So it is basically the digitizer that forms the front screen of your phone. The digitizer flex cable does the job of transferring the signal
Working of the Digitizer
When you touch a point on the digitizer, it stores the digital information as coordinates of that point. It is also saved as the pressure applied at the point of touch this comes of use in some games and apps. This information of the coordinates of touch is communicated to the processing center of the phone. The processor then works on these point data converting it into fluid movement. This movement analysis helps the phone recognize which icon on button was clicked. All these routines happen in a flick of time and bring about quick operations.
Types of Digitizers
Screen digitizers are basically divided into two kinds.
  • Passive digitizers have a top layer that accepts the touch sensation and sends it out as electric signals to the layer below it. The sensors are  placed at the corners of the bottom layer. The electrical charge received at the sensors is evaluated to calculate the point and pressure of the touch received at the surface. These are mostly used in smartphones without a stylus.
  • Active digitizers are used in devices that require high amount of touch sensitivity. These digitizers have their own magnetic field. This magnetic field is affected with a touch on the surface. Being of a single layers, these are highly accurate. The deflection caused in the magnetic layer is analyzed to determine the point coordinates and the power of touch.
When to Change the Digitizer?
The LCD-Digitizer Assembly consist of the following parts :
  • LCD display unit is the location of image display
  • Digitizer flex cable that comes along with the digitizer .
  • The digitizer is the outermost glass layer
The digitizer that plays the role of the touch receptor also acts like a protective cover to the brittle LCD display. When you have a crack in  the front screen but you can see the display screen, then the digitizer can be changed without changing the LCD screen. When you are changing the digitizer at a LA iPhone repair and unlock center, they will change the flex cable also with it. The installation of the flex cable is a very tricky one. A torn or wrongly put flex cable can lead to disrupted images, lines on screen etc. In newer designs, the flex cable comes attached to the digitizer.
If there is no display on the screen, then the whole assembly will have to be changed inevitably. A blank screen will directly point towards a breakage of the  brittle layer of LCD. Sometimes there will be a need to change the whole LCD unit even if the display is working. This is because, most of the newer phone models have the digitizer layer fused to the LCD screen and it is extremely difficult to remove these from each other. Some LA iPhone repair centers will be having high end techniques that can effectively remove the two attached layers. Finding one of these will be a difficult task. Some people try removing them on their own. The LCD layer is very thin and the chances of it getting destroyed is very high. It is therefore best recommended to go for a good LA iPhone  repair and unlock center.
Faults that Occur in Digitizer
  • Hardware problem: This means that the defect with the digitizer screen or the flex cable is responsible for the non-functioning of the touchscreen.
  • Software Issue: The digitizer operation is controlled by certain softwares. These might become corrupted with time or due to some external elements like virus etc.
The technicians at the LA iPhone repair and unlock center will be able to analyze the reason for the fault in the digitizer and do the needful.
Reasons that Cause Digitizer Damage
  • The digitizer is mostly destroyed when the mobile phone  falls down. After you pick it up, it might seem to be in perfect condition but the touch action will not work. This would simply mean that the digitizer has been destroyed.
  • Water Damage: Water that enter in through the phone can clog the functioning of the digitizer. This usually leads to erratic sensing, slow response and wrong responses. Minute errors can be rectified effectively by a full water damage recovery done at LA iPhone repair and unlock centers.
  • Some virus and overheating issues can affect the functioning of the software. Running a virus scan and reverting to factory default settings can help in case of minor sensitivity issues with the digitizer.
Alternative to Changing the Digitizer
Once your digitizer screen is damaged, there no alternative solutions  other than taking to a LA iPhone repair professional. Regardless of how it had happened, there is an available fix for the problem. Even though you can buy the digitizer parts and even the whole LCD assembly unit online, it is recommended not to peddle with the brittle mobile parts if you are not well versed in it. There are several Do-It-yourself videos and guides available online that can guide you through the process of digitizer replacement. The most trickiest part is to fix the flex cable in it place. So the better option would be to take it to an Apple store and ask for a replacement or take to a technician and have it changed.
