Abstract: A micro light emitting diode including an epitaxy layer, a first pad, a second pad, a first ohmic contact metal, a second ohmic contact metal and at least one etch protection conductive layer is provided. The first pad and the second pad are electrically connected to a first type semiconductor layer and a second type semiconductor layer of the epitaxy layer, respectively. The first ohmic contact metal is disposed between the first type semiconductor layer and the first pad. The second ohmic contact metal is disposed between the second type semiconductor layer and the second pad. The at least one etch protection conductive layer is disposed between the first ohmic contact metal and the first pad and/or between the second ohmic contact metal and the second pad. A display panel is also provided.

Abstract: Disclosed are an electrophoretic display device and a method for driving the same. The electrophoretic display device includes a first electrode layer, a second electrode layer, an electrophoretic layer, and a controller. The first electrode layer includes a plurality of pixels formed thereon. The electrophoretic layer is disposed between the first electrode layer and the second electrode layer. The controller looks up a write-in gray level data of each pixel in each frame from a lookup table. The lookup table records the write-in gray level data of each pixel in each frame when a gray level of each pixel is changed from a reference gray level to a required gray level. The present invention is capable of decreasing the lookup table size.
