  • Patent number: 7671929
    Abstract: A pixel element includes a transistor, a pixel electrode and a storage capacitor. The transistor is a switch device of the pixel element. A data signal is applied to the pixel electrode by switching the transistor. The storage capacitor includes the first electrode and the second electrode. Several holes are formed on a surface of the first electrode. Therefore, layers disposed over the first electrode duplicate the shape of the holes, so that the layers have rough surfaces, for increasing the reflectivity.

The backlight module disposed behind the liquid crystal display includes a light-guide plate, a focusing layer, a left backlight source, a right backlight source, and a first V-shaped micro-grooved and a second V-shaped micro-grooved structures of the light-guide plate. The focusing layer is disposed between the light-guide plate and the liquid crystal display. The 3D display method is to instantly switch on and off the left and the right backlight sources to alternately emit the light from the left side and right side of light-guide plate. By means of the first and the second V-shaped micro-grooved structure, the light transmitted from the light-guide plate is focused by the focusing layer within a particular range of angles and passing through the liquid crystal layer for being alternately projected to form a 3D image.
