BlackBerry Torch 9850 Display Replacement

はじめに

This device has an LCD screen. LCD stands for liquid crystal display. An LCD is a flat panel, or an electronic visual display, that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly. Knowing how to replace your LCD is important because Liquid crystal display's are very fragile and break or shatter very easily. It can be very costly to replace an LCD, so knowing how to repair it on your own would be cost efficient as well.
