Abstract:
A pixel structure of a sunlight readable display, comprising:a first thin film transistor comprising a source electrode, a drain electrode and a gate electrode; a second thin film transistor comprising a source electrode, a drain electrode and a gate electrode, said gate electrode of said second thin film transistor being electrically connected to said drain electrode of said first thin film transistor; a first storage capacitor having one end electrically connected to said gate electrode of said second thin film transistor; a third thin film transistor comprising a source electrode, a drain electrode and a gate electrode, said drain electrode of said third thin film transistor being electrically connected to said drain electrode of said first thin film transistor; a second storage capacitor having one end electrically connected to said source electrode of said third thin film transistor and another end connected to a common bus, said second storage capacitor being a liquid crystal capacitor; and an organic light emitting diode display device electrically connected to said drain electrode of said second thin film transistor, said organic light emitting diode display device comprising a half organic light emitting diode display structure and a half reflective liquid crystal display structure; wherein said display is in an organic light emitting diode mode when said third thin film transistor is at an OFF state, and said display is in a liquid crystal mode when said third thin film transistor is at an ON state.
