Abstract: A driving circuit for an electro-luminescence (EL) cell includes an EL cell, and a supply circuit selectively applying current to the EL cell based on a pixel signal from a data line. A control circuit controls current flow from the supplying circuit to the EL cell such that an amount of current for discriminating between gray scale levels is approximately tens of micro-amps.

Abstract: An electro-luminescence panel that is adaptive for displaying a gray scale of picture. In the panel, a plurality of data lines are arranged in such a manner to cross a plurality of gate lines. electro-luminescence cells are provided at each intersection between the gate lines and the data lines. A cell driving circuit is provided at each of the electro-luminescence cells to respond to a signal at the data lines, thereby controlling a light quantity emitted from the electro-luminescence cells. A data driver supplies a voltage pixel signal to the data lines. A plurality of current drivers responds to the voltage pixel signal to control a current amount going through the data lines from the cell driving means.

Abstract: A method for manufacturing an LCD including at least two stacked thin layers in which the upper thin film smoothly and completely covers the lower thin film includes the steps of coating a photo-resist on a patterned layer, patterning the photo-resist by exposing and developing the photo-resist with a mask which has lines and spaces in which a distance between the lines is smaller than a resolution of an exposure system used and etching the metal layer using the patterned photo-resist as a mask.

Abstract: A position sensing liquid crystal display includes a liquid crystal display panel having a first substrate and a second substrate bonded together, and a position sensing digitizer formed as an integral unit on a first or rear surface of at least one of the substrates, whereby minimizing a display panel thickness and allowing an accurate position sensing.
