Transmission/reflection dual-functional electrowetting display panel

A transmission/reflection dual-functional electrowetting display panel, which has two operation modes of transmission and reflection, the transmission/reflection dual-functional electrowetting display panel comprising a plurality of main pixels, each of the main pixels comprising three sub-pixels, the three sub-pixels being a red sub-pixel, a green sub-pixel, and a blue sub-pixel, each of the sub-pixels comprising:

• a first, a second, and a third substrates that are parallel to each other, a light-blocking control layer arranged between the first and second substrates, and a color displaying layer arranged between the second and third substrates, the light-blocking control layer comprising:
• a first reflection electrode and a first transmission electrode that are arranged on the first substrate and a first polar solution and a nonpolar light-absorbing solution arranged on the first reflection electrode and the first transmission electrode, the color displaying layer comprising:
• a second reflection electrode and a second transmission electrode arranged on the second substrate and a second polar solution and a nonpolar color-displaying solution arranged on the second reflection electrode and the second transmission electrode, the first transmission electrode, the second transmission electrode, and the second reflection electrode being made of a transparent conductive material, the first reflection electrode being made of a conductive material having high reflectivity, whereby when the first reflection electrode is driven by applying a driving voltage thereto, the nonpolar light-absorbing solution shrinks to the top of the first transmission electrode and the transmission/reflection dual-functional electrowetting display panel is set in the reflective mode;
• and when the first transmission electrode is driven by applying a driving voltage thereto, the nonpolar light-absorbing solution shrinks to the top of the first reflection electrode and the transmission/reflection dual-functional electrowetting display panel is set in the transmissive mode;
• further comprising:
• a plurality of first upper baffles arranged between the second and third substrates and a plurality of first lower baffles arranged between the first and second substrates, the first upper baffles and the first lower baffles being arranged to correspond to each other so as to divide the transmission/reflection dual-functional electrowetting display panel into a plurality of main pixels;
• wherein the light-blocking control layer further comprises a first electrode protection layer arranged on the first reflection electrode and the first transmission electrode and the first polar solution and the nonpolar light-absorbing solution are arranged on the first electrode protection layer;
• and the color displaying layer further comprises a second electrode protection layer arranged on the second reflection electrode and the second transmission electrode and the second polar solution and the nonpolar color-displaying solution are arranged on the second electrode protection layer;
• wherein each of the main pixels further comprises:
• two second lower baffles arranged between the second substrate and the first electrode protection layer and two second upper baffles arranged between the third substrate and the second electrode protection layer, the second upper baffles and the second lower baffles being arranged to correspond to each other so as to divide the main pixel into a red sub-pixel, a green sub-pixel, and a blue sub-pixel;
• wherein the light-blocking control layer further comprises a first light-blocking baffle, the first light-blocking baffle being arranged on an upper surface of the first substrate and located between the first reflection electrode and the first transmission electrode;
• and
• wherein the color displaying layer further comprises a second light-blocking baffle, the second light-blocking baffle being arranged on an upper surface of the second electrode protection layer and located exactly above a site between the second reflection electrode and the second transmission electrode.
