  • Patent number: 11982798
    Abstract: A projection lens includes a first lens group, a second lens group and an aperture stop. The first lens group is disposed between a reduced side and a magnified side. The second lens is disposed between the first lens group and the magnified side. The second lens group has a light incident surface, a reflective surface and a light emitting surface, the light incident surface faces the first lens group, the light emitting surface faces a projection surface, the light incident surface, the light emitting surface and the first lens group are disposed at a single side of the reflective surface, and at least one of the light incident surface, the reflective surface and the light emitting surface is a freeform surface. The aperture stop is disposed between the first lens group and the second lens group. Moreover, a projection apparatus including the projection lens is also provided.

  • Patent number: 7923312
    Abstract: A fabricating method of a TFT includes first forming a source on a substrate. Then, a first insulation pattern layer is formed to cover parts of the source and the substrate. The first insulation pattern layer has an opening exposing a part of the source. Thereafter, a gate pattern layer is formed on the first insulation pattern layer. Then, the gate pattern layer and a second insulation pattern layer formed thereon surround the opening. Moreover, a second lateral protection wall is formed on an edge of the gate pattern layer in the opening. Afterwards, a channel layer is formed in the opening and covers the second lateral protection wall and the source. Then, a passivation layer with a contact window is formed on the channel layer and the second insulation pattern layer to expose a portion of the channel layer. Thereafter, a drain is formed on the exposed channel layer.
