Abstract: A display device includes a plurality of pixels arranged in matrix, a plurality of gate lines, a plurality of data lines, and a gate driver connected to the plurality of gate lines. The gate driver receives a first scan start signal, a second scan start signal and clock signals and outputs a gate-on voltage to each of the plurality of gate lines. The gate driver outputs the gate-on voltage to the plurality of gate lines such that the gate-on voltages do not overlap with each other when the gate driver receives the first scan start signal. The gate driver outputs the gate-on voltage to at least two of the gate lines at substantially the same time when the gate driver receives the second scan start signal.

Abstract: A driving unit of a display panel includes a control part, a gate driving part, a grayscale compensating part, and a data driving part. The control part provides a control signal and a grayscale signal. The gate driving part provides a gate signal to the display panel. The display panel is divided into a plurality of blocks according to a distance from a light source to each of the blocks. The grayscale compensating part outputs a compensating signal of an n-th frame using look-up tables, and the look-up tables respectively correspond to the blocks of the display panel. The data driving part converts the compensating signal of the n-th frame into a grayscale voltage and provides the grayscale voltage to the display panel. Accordingly, the driving unit of the display panel may improve a response speed of liquid crystals and display quality.

Abstract: Provided are an optical mask, a method of manufacturing a thin film transistor array substrate using the optical mask, and a thin film transistor array substrate manufactured by the method. The method includes forming a data metal layer on a substrate, forming an insulating layer on the data metal layer, patterning a contact hole exposing a portion of the data metal layer and at least one contact projection projecting toward an interior of the contact hole by etching the insulating layer, and forming a pixel electrode or an auxiliary data line terminal electrically connected to the data metal layer through the contact hole and the contact projection.

Abstract: An inventive method for the manufacture of an array of M.times.N thin film actuated mirrors for use in an optical projection system includes the steps of: providing an active matrix; depositing a thin film sacrificial layer; depositing a protective oxidation layer on top of the thin film sacrificial layer; creating an array of empty cavities; depositing an elastic layer; forming an array of conduits in the elastic layer; depositing a second thin film, a thin film electrodisplacive and a first thin film layers, successively, thereby forming a multiple layer structure; patterning the multiple layer structure, until the thin film sacrificial layer is exposed; and removing the thin film sacrificial layer to thereby form an array of M.times.N thin film actuated mirrors. The protective oxidation layer is deposited on top of the thin film sacrificial layer before the formation of each of the empty cavities, which, in turn, prevents phosphorus on the surface of thin film sacrificial layer from getting oxidized.

Abstract: A method for electrically connecting a thin film electrode to a connecting terminal on an active matrix in the manufacture of a thin film actuated mirror is disclosed. The method includes the steps of: forming a thin film sacrificial layer having an empty cavity on top of the active matrix; forming an elastic, a second thin film and a thin film electrodisplacive layers, successively, on top of the thin film sacrificial layer including the empty cavity; forming a contact hole extending from top of the thin film electrodisplacive layer to top of the connecting terminal; forming a first thin film layer on top of the thin film electrodisplacive layer including the contact hole; patterning the first thin film, the thin film electrodisplacive, the second thin film and the elastic layers, respectively; and removing the thin film sacrificial layer, thereby forming the thin film actuated mirror.

Abstract: A method for forming an elastic member in a thin film actuated mirror, the method being capable of controlling a stress built up therein, is disclosed. The method includes the steps of: forming a thin film sacrificial layer; depositing an elastic layer on top of the thin film sacrificial layer by using a CVD method; forming an actuating structure on top of the elastic layer, the actuating structure having a first thin film electrode, a thin film electrodisplacive member, a second thin film electrode and an elastic member; and removing the thin film sacrificial layer. In the present invention, the elastic layer is vertically divided into at least two portions, each of the portions being made of a same material having a different stoichiometry. The stress built up in the elastic layer is controlled by controlling the ratio of the source gases.
