Problems solved by technology

[0007] However, the conventional display 100 only has dielectrophoretic particles 150 of one color, and each pixel unit of the display 100 is Figure 2B In the second operating state, the display effect of the white first electrodes 114a will be interfered by the black dielectrophoretic particles 150
Therefore, the display effect of the conventional display 100 is relatively poor.
[0008] This shows that above-mentioned existing display obviously still has inconvenience and defect in structure and use, and demands urgently further improving
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Abstract

The invention relates to a display, which comprises a first substrate, a spacing element, a second substrate, dielectric fluid, a plurality of dielectrophoresis particles and a plurality of electrophoresis particles. The spacing element is configured on the first substrate. The second substrate is configured on the spacing element which is arranged between the first substrate and the second substrate to form at least one accommodating space. The first substrate or the second substrate is applicable for forming an electric filed in the accommodating space. The dielectric fluid is configured inthe accommodating space and has a first dielectric constant. The dielectrophoresis particles are scattered in the dielectric fluid. Each dielectrophoresis particle has a first color and a second dielectric constant different from the first dielectric constant. The electrophoresis particles are scattered in the dielectric fluid. Each electrophoresis particle has a second color different from the first color. In addition, another display is also provided.
