Abstract
A liquid crystal display (LCD) includes liquid crystal display panel located within a housing. A backlight source is detachably connected to the housing for providing light to the display panel. When the backlight source is removed from the housing, outside light, such as ambient light, provides light to the display panel. The LCD includes a light collecting lens which transmits light to the display panel and which is either covered by the backlight source or exposed to an external light source when the backlight source is detached from the housing. When the backlight source is detached, the LCD has a small size and light weight, making it convenient for carrying and using outdoors. The LCD also consumes less power when the backlight source is detached.
