摘要:
A digital diagnostic system with interchangeable lenses includes a host and at least one optical lens module, wherein the host without any optical lens having curved surface includes a focus adjustment module which drives an image capture module to linearly move. Therefore, the optical system of the optical lens module can be designed independently, and no need to include focus adjustment mechanism, so that the optical design of the optical lens module can be greatly simplified, and the system allows a greater mechanism tolerance, thereby reducing manufacturing difficulty and manufacturing cost.

A method for manufacturing a pixel structure is provided. A thin film transistor is formed on a substrate and an insulating layer is formed to cover the substrate and the thin film transistor. The insulating layer is patterned by a half-tone mask to form a protruding pattern, a sunken pattern connecting the protruding pattern, and a contact window inside the sunken pattern. A transparent conductive layer is formed to cover the protruding pattern and the sunken pattern, and filled in the contact window. A passivation layer is formed to cover the transparent conductive layer. A pixel electrode pattern is formed from the transparent conductive layer by removing a part of the passivation layer located on the protruding pattern, a part of the transparent conductive layer on the protruding pattern, and a part of the passivation layer located within the contact window. A pixel structure manufactured by the method is provided.

An image system adapted to a projection display apparatus includes a first lens group having a negative refractive power, a second lens group having a positive refractive power, an aspheric reflector, and a curved reflector. The second lens group includes an aspheric lens which is the nearest to the light valve in the second lens group.

The aspheric reflector is disposed front of the first lens group for reflecting the image beam passing through the first lens group and second lens group. The curved reflector is disposed above the first lens group for reflecting the image beam reflected by the aspheric reflector onto the screen. The image system has a good imaging quality.
