Embodiment 1

[0097] 40wt% red dye ( red395), 30wt% trimethylolpropane triacrylate (TMTPA), 20wt% dipentaerythritol hexaacrylate (DPHA) and 10wt% phase change material (C 22 OH) were mixed to prepare a phase change ink composition with a melting point of 65°C.

[0098] After injecting the above-mentioned phase-change ink composition into the reservoir, the temperature of the reservoir was set to 75° C., and a voltage of 80 V was applied thereto using an HM-30 print head (manufactured by Dimatix. Inc., discharge volume: 30 pl). The spray is carried out through all 256 nozzles. This discharge was performed on a PET film (manufactured by Lamiace Corp.), and during the discharge, the dot pitch was set to have an interval of 40 μm. After ejection, a line pattern with an average line width of about 50 μm and an average line height of 14 μm was formed. image 3 A shows the shape of the formed pattern after ejection.

[0099] Next, the above-mentioned pattern was pressed using a pressure rolle...

Embodiment 2

[0101] Discharging was performed in the same manner as described in Example 1 except that the dot pitch was set to have an interval of 20 μm, thereby forming a line pattern having an average line width of about 70 μm and an average line height of 20 μm. image 3 B shows the shape of the formed pattern after ejection.

[0102] Next, the above-mentioned pattern was pressed using a pressure roller under the conditions of 60° C. and 0.1 MPa, and the pattern was flattened. Figure 4 B shows the pattern shape after pressing. refer to image 3 B and Figure 4 B, It can be confirmed that the line width of the pattern is widened after pressurization. The line width and line height of the pattern before and after pressing are described in [Table 1] below.

Embodiment 3

[0104] Discharging was performed in the same manner as described in Example 1 except that the dot pitch was set to have an interval of 10 μm, thereby forming a line pattern having an average line width of about 90 μm and an average line height of 28 μm. image 3 C shows the shape of the formed pattern after ejection.

[0105] Next, the above-mentioned pattern was pressed using a pressure roller under the conditions of 60° C. and 0.1 MPa, and the pattern was flattened. Figure 4 C shows the pattern shape after pressing. refer to image 3 C and Figure 4 C, It can be confirmed that the line width of the pattern is widened after pressurization. The line width and line height of the pattern before and after pressing are described in [Table 1] below.

[0106] [Table 1]

Abstract

The present invention relates to a flexible color filter substrate and to a method for manufacturing same. More particularly, the present invention relates to a flexible color filter substrate and method for manufacturing same, the flexible color filter substrate comprising a flexible substrate and R, G, B patterns formed on the flexible substrate. The R, G, B patterns are formed by a phase-change ink composition.

Description

technical field [0001] The invention relates to a flexible color filter substrate and a preparation method thereof, more specifically, to a flexible color filter substrate capable of being used in a continuous process without black matrix, and a preparation method of the substrate. Background technique [0002] Fine patterns of color filters according to the prior art, such as RGB patterns, are mainly prepared by photolithography. However, in the photolithography method, since a pattern is formed by coating an entire area with a photoresist, selectively exposing a pattern using a photomask, and developing an unnecessary pattern portion to remove the portion, unnecessary losses occur. The amount of material used may be relatively high, and a multi-step process may be required, resulting in increased manufacturing costs and thus prolonging the required preparation time. [0003] Meanwhile, while interest in flexible displays is rapidly increasing, research on substituting pla...
