Problems solved by technology
Although flexible color filters have also been developed in recent years, such as the use of low-temperature process color photoresists and high-temperature-resistant high-transparency flexible substrates, such color filters are difficult to obtain in the subsequent lamination process. , due to the flexibility of the flexible substrate, the alignment is not easy, and the characteristics of the thermal expansion of the flexible substrate may also easily lead to inaccurate alignment, thereby reducing the production yield and even affecting the display quality

The invention relates to a manufacturing method of a color electrophoretic display device, comprising the following steps of: providing a substrate provided with a display region and a peripheral circuit region, wherein the peripheral circuit region encircles the display region; then, forming a driving array in the display region of the substrate; then, configuring an electrophoretic display layer on the driving array; and finally, carrying out heat transfer process procedure to form a colorful filtering layer on the electrophoretic display layer. According to the manufacturing method, the production yield of the color electrophoretic display device can be improved, and further the display quality of the color electrophoretic display device can be improved.
Description
technical field [0001] The present invention relates to a manufacturing method of a display device, and in particular to a manufacturing method of a color electrophoretic display device. Background technique [0002] The traditional electrophoretic display device is a black and white display device. In order to make the electrophoretic display device more competitive in the market, the existing technology uses a color filter to make the electrophoretic display device achieve a color effect, so that the electrophoretic display device The device conforms to the current trend of pursuing colorization of flat panel display devices. [0003] At present, the color filter used in the color electrophoretic display device is usually composed of a glass substrate and a color filter pattern disposed thereon. Attaching the color filter to the electrophoretic display layer can make the electrophoretic display device realize the colorization effect. However, because the electrophoretic ...
