Abstract: An LCD device operably switchable between 2D and 3D display modes includes an active retardation panel having a plurality of retardation pixels arranged in at least M*N retardation pixel matrix with a first liquid crystal (LC) layer, and an LCD panel positioned having a plurality of display pixels arranged in at least M*N display pixel matrix with a second LC layer. Each retardation pixel has a first retardation A(i, j), and each display pixel has a second retardation B(i, j). The active retardation panel and LCD panel are arranged such that the retardation pixel matrix is positioned corresponding to the display pixel matrix, and an image displayed from each display pixel and passed through corresponding retardation pixel is simultaneously viewable by left and right eyes of a viewer and satisfies with: L(i,j)=f[A(i+1,j)+B(i,j)], and R(i,j)=f[A(i,j)+B(i,j)]. L(i, j) and R(i, j) are respectively left-eye and right-eye viewed gray levels of the image.

Abstract: A pixel driving circuit includes a driving unit receiving a first control signal via a first control end, and the driving unit is biased according to the first control signal to provide a driving current to a light emitting element. One end of a capacitor is connected to a second control end of the driving unit, and the other end of the capacitor is connected to a first end or a second end of the driving unit. A compensation unit receives a second control signal via a first control end, and the compensation unit is biased according to the second control signal. A first switch unit receives a third control signal via a control end, and thereby the first switch unit is turned on. A second switch unit receives a fourth control signal via a control end, and thereby the second switch unit is turned on. A third switch unit receives a third control signal or a fourth control signal via a control end, and thereby the third switch uni
