Title:
ELECTROWETTING SUPPORT PLATE HAVING HYDROPHILIC SOG MATERIAL AND PREPARATION METHOD THEREOF, AND ELECTROWETTING DISPLAY
Document Type and Number:
WIPO Patent Application WO/2016/078607
Kind Code:
A1
Abstract:
An electrowetting support plate having an SOG material and preparation method thereof, the support plate (5, 6) comprising a substrate (7), an electrode (17) located on the substrate (7), and a hydrophobic insulating layer (15) provided on the electrode (17); the hydrophobic insulating layer (15) is provided with pixel walls (20) thereon; the pixel walls (20) are provided with a hydrophilic SOG material layer on an upper surface thereof, or the pixel walls (20) are made of the hydrophilic SOG material. Also provided is an electrowetting display (1) having the support plate (5, 6). The hydrophilicity of the upper surface of the pixel wall (20) is increased by providing the hydrophilic SOG material layer on the upper surface of the pixel wall (20), thus ensuring the pixel walls (20) made of different materials to have a uniform hydrophilicity, and enabling the hydrophilicity of each region to be uniform. Alternatively, the hydrophilic SOG material is directly selected to prepare the high-hydrophilicity pixel wall (20), thus enabling the surface of the pixel wall (20) in an electrowetting process to have a higher and uniform hydrophilicity, ensuring that a first fluid (11) does not pass over a wall, increasing the quality and reliability of a product, and enabling use in an electrowetting device.
