Problems solved by technology

In recent years, with the improvement of consumer demand, curved surface electrowetting displays have gradually been used by consumers. In the traditional processing method, the whole device is bent into the required curved surface after the electrowetting device is packaged. However, after bending, due to the stress problem of the packaging material, the package will easily fail, and the bent electrowetting display device will easily cause the ink to overturn the wall due to the pressure concentration of the internal liquid. , thereby reducing the service life of the product

Abstract

The invention discloses a manufacturing method of an electrowetting display device, and a curved-surface electrowetting display device. The manufacturing method of the electrowetting display device comprises the following steps: S1, a curved-surface-shaped upper substrate and a curved-surface-shaped lower substrate are aligned and attached; and S2, the upper substrate, the lower substrate and a device located between the upper substrate and the lower substrate are packaged to form the curved-surface electrowetting display device. Before packaging, as the upper substrate and the lower substrateare of curved-surface structures, the electrowetting display device is manufactured by adopting the method of forming the curved-surface substrate firstly and then packaging, so that the problem of packaging failure caused by stress generated by a packaging material after bending and the problem of ink rollover caused by internal liquid pressure concentration are avoided. The invention also provides the curved-surface electrowetting display prepared by the method.

Description

technical field [0001] The invention relates to the technical field of electrowetting displays, in particular to a manufacturing method of an electrowetting display device and a curved surface electrowetting display device. Background technique [0002] The electrowetting display is a reflective display device, which reflects the external light source through inks of different colors to achieve a full-color display effect. The electrowetting display has low energy consumption, wide color gamut, and high response. , high contrast, visual health and other advantages, so it is considered to be one of the mainstream display technologies in the future. In recent years, with the improvement of consumer demand, curved surface electrowetting displays have gradually been used by consumers. In the traditional processing method, the whole device is bent into the required curved surface after the electrowetting device is packaged. However, after bending, due to the stress problem of th...
