Abstract

The invention provides a pixel structure which comprises a first substrate, a second substrate, multiple separator walls, multiple first pixel electrodes, multiple second pixel electrodes, a first color display medium, a black display medium, a light-transmitting display medium and a color light filter sheet. The separator walls are arranged between the first substrate and the second substrate. The first pixel electrodes and the second pixel electrodes are respectively arranged between the first substrate and the second substrate. The color display medium and the black display medium are respectively arranged on the first substrate and the second substrate. The light-transmitting display medium is arranged between the first substrate and the second substrate. The color light filter sheet is disposed on the first substrate or the second substrate. The color light filter sheet and the color display medium which are in the same sub-pixel area that is divided by separator walls have partially overlapped light spectrum.

Description

technical field [0001] The present invention relates to a pixel structure, in particular to a pixel structure utilizing the principle of electro-wetting. Background technique [0002] In the traditional electronic paper (Electronic Paper) display technology, charged balls are usually arranged between two substrates. The ball is white on one side and black on the other. When a bias voltage is applied between the substrates to create an electric field, the balls can rotate to direct the displayed color toward the user. Therefore, traditional electronic paper can display black and white images. Later, Joseph Jacobson developed another electronic paper display technology in the 1990s. This technology replaces traditional pellets with microcapsules. The microcapsules are filled with colored oil and charged white particles. When a bias voltage is applied to form an electric field, the capsule can be made to face the user in white or in the color of oil. Although it is possib...
