Color display apparatus and manufacturing method thereof

Abstract

A color display apparatus is provided. The color display apparatus includes a black-and-white display module and a color filter layer, wherein the color filter layer is disposed on the black-and-white display module. The color filter layer includes a translucent base and a plurality of color filter patterns, wherein the translucent base is disposed on the black-and-white display module. The color filter patterns are embedded in the translucent base, and a first surface of each color filter pattern away from the black-and-white display module is exposed from a second surface of the translucent base away from the black-and-white display module, wherein the first surfaces and the second surface are coplanar, and the first surfaces and the second surface are in contact with a dielectric gas or covered by a protective layer. A manufacture method for the color display apparatus is also provided. The apparatus and the method has an advantages of high production efficiency.

Description

technical field [0001] The invention relates to a display device, in particular to a color display device and a manufacturing method thereof. Background technique [0002] With the development of flat-panel display technology, various flat-panel display devices have been launched one after another to meet the needs of consumers, and electrophoretic display devices (electrophoretic display apparatus) have the advantages of power saving, light weight and thinness, etc., making the electrophoretic display device Apps are also becoming more and more popular. Early electrophoretic display devices can only display black-and-white grayscale images. In order to enable the electrophoretic display device to display color images, the prior art proposes a method of adding a color filter to the electrophoretic display device. [0003] figure 1 It is a schematic diagram of an existing color electrophoretic display device. Please refer to figure 1 , the existing color electrophoretic ...

Problems solved by technology

[0005] However, the sealant layer 140 is a liquid colloid before it is cured, and it is easy to overflow and stick to the sides of the carrier plate 136 and the thin glass plate 132, so that after the liquid colloid is solidified, the carrier plate 136 and the thin glass plate 132 are adhered to each other and are not easy to separate.

In this way, the production efficiency of the existing color electrophoretic display device 100 will be affected

In addition, because the existing color electrophoretic display device 100 achieves the purpose of display by reflecting the external light source, the existence of the thin glass plate 132 will cause part of the external light source to be directly reflected by the thin glass plate 132 and cannot be transmitted to the front plate 120, resulting in The light utilization efficiency of the color electrophoretic display device 100 becomes worse

Moreover, part of the light source reflected by the thin glass plate 132 will also affect the image display quality.
