The present invention discloses a liquid crystal lens and a manufacturing method thereof. At least one first electrode is disposed on a first substrate, a first alignment layer is disposed on the first electrode, a liquid crystal layer is disposed on the first alignment layer, a second alignment layer is disposed on the liquid crystal layer, an electric field uniformization layer is disposed on the second alignment layer, at least one second electrode and at least one third electrode are disposed on the electric field uniformization layer, and the second electrode is arranged around the third electrode. A second substrate is disposed on the second electrode and the third electrode. The third electrode which matches up with the second electrode produces an electric field gradient and the liquid crystal layer is affected uniformly by the electric field uniformization layer so as to achieve rapid focus purpose by the liquid crystal.

A method, image processing apparatus, and computer readable medium for image enhancement are provided. In the method, a low-resolution image is received and upscaled to generate an upscaled image having first pixels. Edge detection is performed on the upscaled image to obtain edge information of the first pixels. Each piece of the edge information includes an edge direction and an edge intensity, and each of the edge directions includes a horizontal and vertical component having a constant summation. A non-edge region of the upscaled image is enhanced to generate a high-resolution detail image; based on unsharp masking sharpening methods, an edge region of the low-passed upscaled image is enhanced according to the horizontal and vertical components of the edge directions to generate a high-resolution edge image. Image fusion is performed on the high-resolution edge image and the high-resolution detail image according to the edge intensities to generate a super-resolution image.

A thin film transistor comprises a transparent substrate, a gate is disposed on the transparent substrate, a gate insulator is disposed on the gate and the transparent substrate, an active layer is disposed on the gate insulator, an electrode layer is electrically connected the active layer and the portion of the active layer is exposed, and an ultraviolet light absorbing layer is disposed on the electrode layer. By using the advantage of the ultraviolet light absorbing layer with the range of visible light transmittance and with the component protection, preventing the optical characteristics of the thin film transistor from the outside moisture is achieved, and by adjusting the parameters in the thin film deposition process to change its conductivity.
