Abstract

A display includes a gravity sensor, a timing controller, a backlight module, a first liquid crystal panel, a liquid crystal driver, and a second liquid crystal panel. The gravity sensor generates a direction signal. The timing controller receives a three-dimensional image, outputs a left eye image and a right eye image of the three-dimensional image in turn, outputs a control signal, and outputs a backlight control signal. The backlight module turns on a backlight. The first liquid crystal panel receives and displays the left eye image and the right eye image of the three-dimensional image. The liquid crystal driver receives the control signal and the direction signal, and outputs a voltage control signal. The second liquid crystal panel rotates liquid crystals within the second liquid crystal panel according to the voltage control signal.
