Problems solved by technology

The color filter will absorb light, resulting in poor light utilization efficiency of the electrophoretic display device, which will reduce the brightness, contrast and color saturation of the electrophoretic display device, especially the color saturation
[0005] On the other hand, the conventional technology has developed an electrowetting display device, which is a color display device, but it has the disadvantage that the picture is not black enough
In other words, electrowetting display devices have po

Abstract

The invention discloses a color display device, comprising a substrate, a protective layer, an electrophoresis-type display module, an electrowetting-type display module and a first insulating layer. The protective layer is opposite to the substrate, wherein the protective layer and the first insulating layer are made of transparent materials; the electrophoresis-type display module is arranged between the substrate and the protective layer, wherein the electrophoresis-type display module is a white and black display module; the electrowetting-type display module is arranged between the substrate and the protective layer, wherein the electrowetting-type display module is a color display module; and the first insulating layer is arranged between the electrophoresis-type display module and the electrowetting-type display module. The color display device has high color saturation and high contrast.

Description

technical field [0001] The invention relates to a display device, in particular to a color display device. Background technique [0002] With the rapid development of display technology, flat panel display devices have been more and more widely used in various display fields. The electrophoretic display device has become an increasingly important flat-panel display device due to its advantages of low energy consumption, high reflectivity and high contrast. [0003] Currently, conventional electrophoretic display devices generally include an electrophoretic layer, and the electrophoretic layer is located between two electrode layers. The electrophoretic layer includes a plurality of charged particles, and the colors of these charged particles usually include black and white. When a voltage is applied to the electrode layer, these charged particles are driven to move so that each pixel (ie pixel, referred to herein as a pixel) of the electrophoretic display device can displa...
