Patent ID: 8780308

Claim:
A pixel structure, comprising: a first substrate; a first gate line and a second gate line, disposed on the first substrate; a data line, disposed on the first substrate and intersecting the first gate line and the second gate line; a pixel unit disposed between the first gate line, the second gate line and the data line, the pixel unit comprising: a first active element electrically connected to the first gate line and the data line; a second active element electrically connected to the second gate line and the data line; a first sub-pixel electrode electrically connected to the first active element; a second sub-pixel electrode spaced apart from the first sub-pixel electrode, and electrically connected to the second active element; and a common electrode opposite to the first sub-pixel electrode and the second sub-pixel electrode, wherein the first and second sub-pixel electrodes or the common electrode has at least one slit pattern; a second substrate comprising a counter electrode, wherein the counter electrode is disposed on a surface facing the first substrate, and the counter electrode is corresponding to the first sub-pixel electrode; and a display medium disposed between the first substrate and the second substrate, wherein when the counter electrode is applied with an electrical potential that is between an electrical potential of the common electrode and an electrical potential of the first sub-pixel electrode, the pixel structure is operated in a narrow viewing angle mode; when the counter electrode is floating, the pixel structure is operated in a wide viewing angle mode.
