摘要:
A switch controlling device for a serial communication port and a light communication port having an asynchronous communication part, a switch, a micro-controller, multiplexers, an EIA driver, and a light signal input/output part. The switch controlling device for the serial communication port and the light communication port is driven by a user selecting the serial communication port or the light communication port, after both the serial communication port and light communication port have been installed in a computer system.
摘要:
Disclosed is a method for fabricating a liquid crystal display device with a repair structure, comprising a substrate; a plurality of thin film transistors arranged in matrix, each of the thin film transistors including a gate electrode, a gate insulating layer, a semiconductor layer, an ohmic layer and a source/drain electrode which are formed on the substrate; a plurality of pixel electrodes arranged alternatively with respect to the thin film transistors; a plurality of gate bus lines extended between the pixel electrodes arranged in two adjacent rows and commonly connected with gates of the thin film transistors arranged in the same row; a plurality of data bus lines extended between the pixel electrodes arranged in two adjacent columns and commonly connected with the source electrodes of the thin film transistors arranged in the same column; and a passivation layer thereon. The fabricating method comprises the steps of depositing the passivation layer having an opening pattern wider than the pixel electrode to expose entire surface of the pixel electrode and expose a portion of the gate insulating layer between the pixel electrode and the passivation layer; and re-etching a short portion between the pixel electrode and the bus line using the passivation layer as a mask to repair the short portion. Thus, the liquid crystal display device is improved in reliability and a yield of its production can be improved.
