  • Patent number: 9341950
    Abstract: An exposure apparatus is provided and adapted for exposing a photoresist layer on a layer to form a plurality of strip exposed patterns. The exposure apparatus includes a light source, a lens group and a mask. The lens group is disposed between the photoresist layer and the light source and includes a plurality of strip lens parallel to each other, wherein an overlapping region between any two neighboring strip lens is defined as a lens connecting region, and the other regions excluding the lens connecting regions are defined as lens regions. The mask is disposed between the photoresist layer and the lens group and includes a plurality of shielding patterns, wherein an outline of the shielding patterns corresponds to the strip exposed patterns, each shielding pattern has a strip opening, and an extension direction of the strip openings is substantially parallel to an extension direction of the shielding patterns.

  • Patent number: 8312506
    Abstract: A digital television setting information storage apparatus and a method for accessing digital television information are provided. The apparatus includes a random access memory and a non-volatile memory. The method includes steps of: receiving a setting information change signal, storing setting information into the random access memory, clearing the non-volatile memory, and transferring the setting information from the random access memory to the non-volatile memory when the non-volatile memory is erased. The setting information includes channel information and on screen display setting information.
