Who Makes Digitizer for the LCD?

      Digitizer is a very important component of an LCD screen. Digitizer is a tricky term because many people tend to confuse it. Some people think only the glass piece is the digitizer of an LCD while others think the adjacent flex cable is the digitizer. Actually, the digitizer consists of both the glass piece and the flex cable. The process of producing digitizers requires hi-tech machineries and a group of technicians. The process of maintaining the same quality of every digitizer piece is also a daunting task. It requires a great manufacturing factory. Many LCD screen wholesaling company don’t have good manufacturing factories. That’s why the probability of producing faulty digitizers by these companies is very high. ‘Unified Wireless Inc.’ is a great LCD wholesaling company in Queens, NY. It sells amazing models of LCD screens such as the iPhone 6s LCD screen. The company is collaborated with a great manufacturing factory called ‘Shenzhen Factory’ in China. Shenzhen Factory is a renowned factory which has international recognition. The factory has a great accuracy rate. The factory barely produces any faulty digitizer. This is the reason why UW has been so successful in the LCD screen wholesaling market. UW’s customers are very contended with the company.

    Well, if you don’t have much knowledge about digitizers, then this article can help you. The digitizer by definition is a device used to convert analog signals into digital signals.  In the case of our cell phones, this device would be the glass that covers the LCD.  Yes, the glass piece that is attached to the LCD is the digitizer... or sometimes called LCD digitizer.  It converts your actions (press, swipe, etc) into a digital signal that your phone understands.  The data from the digitizer (glass) is transferred to the phone by the attached digitizer flex cable or digitizer flex ribbon (that should be included in your purchase of a replacement LCD digitizer).

    The digitizer's main function is to protect the fragile LCD, as well as to transfer all of the touch functions (swipe, press, zoom, etc) to the LCD. The touch action on the Digitizer glass is transferred through the Digitizer flex cable, so the LCD image can respond accordingly. The Digitizer flex cable should already come installed on the glass digitizer. This is where things can get confusing- an LCD Digitizer assembly is actually these two parts fused together. Usually, the glass is called front glass or touch panel but not the digitizer. The real digitizer is the one between the front glass and LCD, which also is crystal colored and with the flex cable. You can see the picture, one is the front glass with digitizer and the other is the front glass only. And nowadays, the glass, the digitizer and the LCD are integrated all together with professional machine. That's why it's more and more difficult to replace the glass or LCD only.

      To properly understand how the digitizer actually works with different layers of an LCD screen, you need to have some basic idea about the layers of an LCD screen. Well, you can see that in the middle of the figure, there is a layer called the ‘Liquid Crystal’ layer. There are two glass made ridges above and below it to sandwich that layer. Another two layers of polarizer perfectly sandwich these layers respectively. The reflective surface backlight is positioned in the furthest while the anti-glare layer is placed on the front of the whole structure. The green and white layers can enhance the reaction of the screen touch.

     The digitizer glass consists of two polarized glasses. There is liquid crystal substance between these glasses. On the uppercase polarized glass there is a pixel controlling configuration. The lowercase polarized glass is placed on the backlight of the LCD screen. The liquid crystal substance supports voltage deficient conductivity. This is how the digitizer glass works.

   There is another representation of the structure of an LCD to make things clearer to you. The main function of the Polarizer layers is to modify and direct the light in a definite direction. Under the topmost polarizer, there is a ‘Color Filter Layer’ which helps to filter different wavelength rays. The TFT layers refer to the ‘Thin Film Transistor’ which are otherwise known as liquid crystal layers. So, it doesn’t matter whether the LCD is an iPhone 6s LCD screen will be lesser.

 

or iPhone 7 LCD, the basic structure is always the same.

    Flexible, flat cables are used in place of round cables for easy cable management, especially in high-flex applications. They usually take up less space than round cables, often offering better EMI/RFI suppression and eliminating wire coupling issues. In addition, because the wires are protected individually and not wrapped many times over by different materials as round cables are, they are lighter in weight and offer greater flexibility. There are several conductors placed on the flex cable. The distance between two conductors is known as pitch.  The Silicone rubber is used to 'mold' a flat cable containing multiple conductors of the same size. That flex cable in the picture is used in manufacturing the iPhone 6s LCD screen.
