BlackBerry Passport LCD Backlight Repair
A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light themselves, they need illumination (ambient light or a special light source) to produce a visible image. Backlights illuminate the LCD from the side or back of the display panel.
BlackBerry Passport LCD screen is built with an internal light source which consists of several layers. The backlight is usually the first layer from the back. But in order to create screen images, a mechanism is needed to regulate the light intensity of the screen’s pixels. For this, light valves are used that vary the amount of light reaching the target by blocking its passage in some way. The most common element is a polarizing filter to polarize the light from the source in one of two transverse directions and then passing it through a switching polarizing filter, to block the path of undesirable light.
There can be several reasons for your BlackBerry Passport backlight to malfunction resulting in dim or no backlight at all. It can be caused by components in the internal circuitry of your BlackBerry or it can be the LCD screen itself. If your BlackBerry displays any of the mentioned symptoms then it is time to get your device fixed by a professional.
