Abstract

The invention provides a pixel structure provided with a plurality of sub pixel areas. The pixel structure includes a first substrate, a second substrate, a full-color display medium, a black display medium, a transmitting display medium and a full-color filtering layer. The full-color display medium is arranged on the first substrate and includes a first color liquid drop, a second liquid drop and a third liquid drop. The first color liquid drop, the second color liquid drop and the third color liquid drop are arranged in different sub pixel areas. The black display medium is arranged on the second substrate. The transmitting display medium is arranged between the full-color display medium and the black display medium. The full-color filtering layer includes a first color pattern. The first color pattern and the first color liquid drop are disposed in the same sub pixel area and the first color pattern and the first color liquid drop are in the same color.

Description

technical field [0001] The invention relates to a pixel structure, in particular to a pixel structure for displaying color pictures. Background technique [0002] In current electrowetting display devices, dyes or pigments are mostly added to the non-polar liquid layer to form a color medium. However, there are not many choices of non-polar soluble dyes on the market, and in order to make the color medium have a better absorption coefficient, the dye structure must contain specific functional groups, which may also cause the solubility of dyes in non-polar liquids Reduced, affecting the performance of component colors. [0003] In other words, the color saturation of the current electrowetting display device is not good. However, if it is chosen to increase the travel length of light in the color solution to improve color performance, it is necessary to increase the thickness of the non-polar liquid layer in the display device, which may affect the driving performance of t...
