Abstract

The invention discloses a piece of ink filling equipment and an ink filling method for electrofluidic displays. Ink is applied to a lipophilic and hydrophobic carrier to at least form a to-be-transferred oil film of which the size matches the size of a display area of a display substrate, wherein the lipophilicity of the carrier is weaker than that of a hydrophobic layer in a pixel grid; and the to-be-transferred oil film of the carrier is made to correspondingly contact a part, with a pixel grid, of the display substrate so as to enable the ink applied to the carrier to transfer to the pixel grid, thus completing oil filling. By adopting the method to carry out ink filling on an electrofluidic display, oil filling is uniform, the controllability is good, and the filling speed is high. The equipment and the method are suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of electrowetting display preparation, in particular to a device and a method for filling ink into pixel grids of a display substrate of an electrowetting display. Background technique [0002] Electrofluidic Display (EFD, Electrofluidic Display), also known as electrowetting, is a display technology that controls the surface layer of the surrounded liquid by controlling the voltage, resulting in changes in pixels. [0003] refer to Figure 1a , Figure 1b , Figure 1c and figure 2 , the structure of the electrowetting display mainly includes a first conductive plate 1 and a second conductive plate 3 arranged oppositely, and a first fluid 7, a second fluid 8, an insulating material between the first conductive plate 1 and the second conductive plate 3 Layer 4, a hydrophobic layer 5 and a plurality of pixel walls 6. Wherein, an encapsulation frame 2 is further provided on the first conductive plate 1 , a...
