摘要： A method includes: controlling a first layer of a panel so that first electrical signals generated based on the first driving signal are applied to first cells of the first layer, and light incident on the first layer is modulated into a first modulated light according to the first electrical signals; and controlling a second layer of the panel so that second electrical signals generated based on the second driving signal are applied to second cells of the second layer, and the first modulated light received from the first layer is modulated into a second modulated light according to the second electrical signals. A modulation resolution of the second modulated light output from the second layer is greater than that of the first modulated light due to at least two second cells of the second layer that modulate light modulated by one first cell of the first layer.
