An exemplary backlight module (11) includes a light guide plate (12), a reflector (18), and a light emitting diode unit (142). The light guide plate includes a light incident surface (122) and a diffusion pattern (126) located on the light incident surface. The reflector is positioned at a side of the light guide plate corresponding to the light incident surface, and has a reflection pattern (184) thereon. The light emitting diode unit is between the light incident surface and the reflector.
摘要:
An exemplary liquid crystal display (LCD) provides data lines, gate lines, and pixel units arranged as a matrix array. A method for driving the LCD includes a step of analyzing and determining polarities of one column of the pixel units as determining pixels, thereby defining a first polarity group and a second polarity group, and a step of sequentially applying corresponding data signals to a part of the whole pixel units that are arranged at same rows with the first polarity group in a part of a period of a frame. Corresponding data signals are sequentially applied to the other part of the whole pixel units that are arranged at same rows with the second polarity group in another part of a period of a frame.
