Abstract
An electrowetting display device including a display panel that includes a display area in which a plurality of pixels is partitioned by a partition wall and a non-display area, a data driver that applies data voltages to the pixels through a plurality of data lines, and a gate driver disposed in the non-display area to apply gate signals to the pixels through a plurality of gate lines. The pixels receive the data voltages in response to the gate signals and display gray scales corresponding to the data voltages, and the partition wall is extended in the non-display area to cover the gate driver.
Claims21
An electrowetting display device comprising:
- a peripheral area at least partially surrounding rows and columns of pixels,
- a first substrate;
- a second substrate facing the first substrate;
- a fluid disposed between the first substrate and the second substrate;
- a data driver configured to apply data signals to the rows and columns of pixels through a plurality of data lines;
- a gate driver disposed at least partly in the peripheral area and configured to apply gate signals to the rows and columns of pixels through a plurality of gate lines, wherein the rows and columns of pixels are configured to receive the data signals in response to the gate signals and to display gray scales corresponding to the data signals;
- and
- a single contiguous material layer that includes:
- (i) a grid structure comprising intersecting rows and columns of partition walls that partition the pixels, and (ii) a non-grid structure that at least partly covers the gate driver in the peripheral area, the pixels containing respective portions of the fluid.
A display device comprising:
- a substrate comprising a peripheral area at least partially surrounding rows and columns of pixels;
- an electrically conductive and polarizable fluid disposed on the substrate;
- a data driver configured to apply data signals to the pixels through a plurality of data lines;
- and
- a gate driver disposed in the peripheral area and configured to apply gate signals to the pixels through a plurality of gate lines;
- a first insulating layer disposed on the substrate in the peripheral area and on the gate driver;
- a second insulating layer disposed in the peripheral area and on the first insulating layer and the gate driver;
- and
- a single contiguous material layer having a grid structure disposed among the rows and columns of pixels, disposed in the peripheral area and having a non-grid structure, disposed on the second insulating layer, disposed on the first insulating layer, and disposed on the gate driver, wherein the single contiguous material layer at least partially covers the gate driver in the peripheral area and comprises the grid structure of intersecting rows and columns of partition walls that partition the pixels and contain the fluid portions within the respective individual pixels, the pixels containing respective portions of the electrically conductive and polarizable fluid.
