Electrophoretic display
View Patent ↗A electrophoretic display is provided, which includes a first electrode formed on a first substrate, a second electrode formed on a second substrate facing the first substrate, a plurality of partitions dividing the domain between the first and second electrodes into a plurality of domains, and a plurality of charged particles colored by one among red, green, and blue, and dispersed in each domain.
1. An electrophoretic display, comprising:
a first electrode arranged on a first substrate;
a second electrode arranged on a second substrate facing the first substrate;
a partition dividing a region between the first electrode and the second electrode into a plurality of domains;
a gate line arranged on the first substrate; and
a data line intersecting the gate line and arranged on the first substrate;
a thin film transistor coupled with the gate line and the data line;
wherein each domain comprises one type of a plurality of charged particles consisting of red charged particles, green charged particles, and blue charged particles; and
wherein the partition is arranged on the data line.
2. The electrophoretic display of claim 1 , wherein adjacent domains contain a different type of the plurality of charged particles.
3. The electrophoretic display of claim 1 , further comprising:
a plurality of black charged particles dispersed in each domain.
4. The electrophoretic display of claim 3 , wherein the black particles are charged with opposite polarities as the polarities of the red charged particles, green charged particles, and blue charged particles.
5. The electrophoretic display of claim 1 , wherein the first electrode is divided into a plurality of portions corresponding to the plurality of domains.
6. The electrophoretic display of claim 1 , further comprising:
a passivation layer provided between the thin film transistor and the first electrode.
7. The electrophoretic display of claim 1 , wherein a center portion of the second electrode is recessed in each domain.
8. An electrophoretic display comprising:
a first electrode arranged on a first substrate;
a second electrode arranged on a second substrate facing the first substrate;
a partition dividing a region between the first electrode and the second electrode into a plurality of domains; and
an overcoat arranged between the second electrode and the second substrate;
wherein each domain comprises one type of a plurality of charged particles consisting of red charged particles, green charged particles, and blue charged particles; and
wherein a center portion of the overcoat is recessed in each domain.
9. The electrophoretic display of claim 1 , further comprising:
a fluid in each domain that includes the charged particles.
10. The electrophoretic display of claim 9 , wherein the second electrode comprises a plurality of recessed portions.
11. The electrophoretic display of claim 10 , wherein the recessed portions correspond to each domain.
12. The electrophoretic display of claim 10 , further comprising:
an overcoat provided between the second electrode and the second substrate and having raised portions and recessed portions,
wherein the recessed portions of the second electrode are arranged according to the raised portions and the recessed portions of the overcoat.
13. The electrophoretic display of claim 8 , wherein the second electrode comprises a plurality of recessed portions; and
wherein the recessed portions of the second electrode are arranged according to the recessed portions of the overcoat.
