What is a Touch Screen Digitizer?
A touch screen digitizer is the part of a personal digital assistant (PDA), phone or monitor that allows you to touch the screen with a stylus or your finger and input data directly. You can touch icons to activate them, or you can even use handwriting recognition to input text on some touch screens. Others use virtual keyboards to input data. Using a stylus, which has a smaller and more precise tip than a finger, you are activating a much smaller area of the digitizer. This, in essence, gives you a finer line and the perception of more writing space.
- Input: The digitizer is a thin, clear film over your device's display that tells the device exactly where you have touched the screen. It is made of two layers of film that contain conductive points in them. They are held slightly apart by a thin, non-conductive mesh. When you press against the film, it completes a circuit where you touch and tells the device those coordinates
- Smartphones: The digitizer is the main or only input device for some of today's smartphones. Apple's iPhone and the Palm Pre are good examples of the use of a digitizer. Their highly graphic operating systems use various gestures or patterns of touch to mean different things. A touch and swipe to the side can turn a page or change screens while a tap can activate a function
- PDAs: Like smartphones, personal digital assistants (PDAs) sometimes include a keypad, but more often rely heavily or completely on the touch screen digitizer for input. Windows Mobile and Palm devices both have methods of entering text into the device using the digitizer
- Text Entry by Gestures: The original Palm text entry system called Graffiti used gestures to decide what letters you were using and you had to learn to print the letters a certain way. A stroke down and a tap at the top created a lower-case 'i' on the screen. The Windows version uses a more sophisticated recognition system to find patterns that look like letters
- Point-of-Sale (POS) Applications: Point-of-sale (POS) applications are another broad area where touch screen digitizers are used. In this use, they are applied to a full-sized computer monitor to create a touch screen. The two films are larger and often not as precise as their smaller cousins on phones and PDAs. They are acting basically as the mouse in the POS application, so the clerk can press virtual buttons. The precision involved in handwriting recognition is not required in this application
How to Troubleshoot an HTC Touchscreen?
HTC is a Taiwanese cell phone manufacturer responsible for hundreds of phone models, almost all of them touch-enabled smartphones. These phones are powerful, complex, and multi-faceted, and a variable touchscreen interface is pretty much the only way to successfully control such sophisticated hardware in such a small package. It's not uncommon for a smartphone to lose sensitivity or accuracy in its touchscreen. HTC's product lineup focuses on phones running the Windows Mobile and Android operating systems, and knowing how to adjust the touchscreen is imperative to successful operation of both
- Press the "Home" key and press "Start." Use the directional pad to highlight "Settings," then press the center or "Enter" button
- Use the directional pad to select the System tab. Select "Screen," then press the center or "Enter" button. Select "Align Screen."
- Using your smartphone's stylus, tap the crosshairs as they appear on your screen. Do this for as many as appear, until the calibration tool finishes. Your screen is now properly calibrated
- Press the "Home" button or capacitive area, then press "Menu." Tap "Settings."
- Tap "Language and keyboard." Tap "Keyboard settings." Tap "Tutorial" and go through the steps that appear on your screen
- Once this is finished, turn your phone off and on again. Your keyboard has been adjusted, which activates a re-calibration of the capacitive touchscreen. (Capacitive screens are technically far more accurate that resistive, and so a full calibration tool is not included with Android phones.)
Tips & Warnings
- If you continue to have problems with your HTC smartphone's touchscreen, it may be a hardware error with the digitizer or the screen itself. If this is the case, contact HTC Customer Support at 866-449-8358, or check the Support web page for your particular model (see Resource)
