We have all heard of an LCD and touchscreen but what exactly is the difference? Most of us had to deal with a broken touchscreen or LCD at one time or another, especially with smartphones. But how well do you know this device? You should know it pretty well since we use them everyday in our phones, laptops, and even radios!
We’re going to focus on a radios’ LCD display and touchscreen and go over the difference between the two parts.
A touchscreen is defined as "a display device which allows the user to interact with a computer by touching areas on the screen". In a radio, the touch screen or digitizer is the input portion of the radio. This thin piece of resistive or capacitive electrically charged glass is as thin as 1.1 mm. Using your finger allows for haptic responses to control the radio and some vehicle functions. A ribbon cable allows for integration into the main circuit board that powers the LCD, touch screen and any buttons built into the radio.
Types Of Damage
When the touchscreen is broken, you will still see what is on the screen, the screen should operate as normal. Like when you break your phone screen and can still operate the device. While it’s design may seem delicate and fragile, they are made to withstand the constant vibrations of daily driving. Any force greater than a finger tap is more likely to cause damage in the form of a spider web crack. Other foreign objects such as car keys, 2x4s, and the occasional matchbox race car can dent or completely shatter the touch screen; even the LCD!
The Liquid Crystal Display (LCD) is the output portion of the radio that displays all radio functions and features. An LCD screen is what displays the image from inside of the device. Without the LCD, the radio brain or module cannot be used to its full potential. Today’s car and truck radios act as infotainment hubs providing both in-vehicle entertainment and live information.
Types Of Damage
When the LCD is broken and/or damaged, you may still be able to use the touchscreen depending on how bad the damage is. When broken, the panel will have dark blobs or a viscous substance and most likely will have a spider web type crack. While the touchscreen seems to act as a protective barrier, any defect can cause secondary damage to the LCD deeming both pieces scrap. Isolated LCD damage with no damage to the touch screen is possible and has been witnessed by our techs; the cause of which is due to some dropping or the impact from a car wreck. The LCD has a thin ribbon cable that connects into a circuit board that powers the LCD, touchscreen and any buttons built into the radio.
