Abstract:
A display device is provided. The display device includes a display area having display pixels arranged in a matrix shape, and a dummy area that is formed proximate to an edge of the display area and that has a plurality of dummy pixels. Each dummy pixel includes a first electrode, a second electrode for receiving a common voltage, a liquid crystal layer formed between the first electrode and the second electrode, and a voltage supplier for supplying the first voltage to the first electrode. By removing a thin film transistor of a dummy pixel and directly applying a common voltage to a pixel electrode, the thin film transistor of the dummy pixel is destroyed when static electricity is introduced from the outside, thereby preventing static electricity from being introduced to the display area.

A level shifter and a display device having the same are provided. In a level shifter, a first transistor includes a gate electrode receiving a first driving voltage, and a source electrode receiving an input signal through an input terminal. A second transistor includes a drain electrode receiving the first driving voltage, and a source electrode electrically connected to a drain electrode of the first transistor through a first node. A third transistor includes a source electrode receiving a second driving voltage, a drain electrode electrically connected to a gate electrode of the second transistor through a second node, and a gate electrode receiving the input signal. A fourth transistor includes a drain electrode receiving the first driving voltage, a gate electrode electrically connected to the drain electrode of the first transistor through the first node, and a source electrode electrically connected to the drain electrode of the third transistor through the second node. An inverter inverts a signal outputted from the second node to apply the inverted signal to an output terminal.
Abstract:
In methods of manufacturing a capacitor and a semiconductor device, a mold layer is formed on a substrate having a contact plug. The mold layer includes an opening exposing the contact plug. A conductive layer is formed on the contact plug, an inner sidewall of the opening and the mold layer. A photoresist pattern is formed to substantially fill the opening. A cylindrical lower electrode is formed by partially removing the conductive layer. The mold layer is selectively removed while the photoresist pattern prevents damage to the lower electrode, the contact plug and the substrate. The photoresist pattern is removed, and then a dielectric layer and an upper electrode are sequentially formed on the lower electrode. Damage to the lower electrode and the contact plug are effectively prevented due to the presence of the photoresist pattern during selective removal of the mold layer.

A method for fabricating a clich{acute over (e,)} including: providing a transparent glass substrate; depositing a metal layer on the substrate; patterning the metal layer and thereby forming a first metal pattern; etching the glass substrate by using the first metal pattern as a mask and thereby forming a first convex pattern; patterning the first metal pattern and thereby forming a second metal pattern; and etching the first convex pattern by using the second metal pattern as a mask and thereby forming a second convex pattern.
Abstract:
A TFT array panel is provided, including an insulating substrate, gate lines horizontally provided on the insulating substrate, data lines isolated from the gate lines and intersecting the gate lines, a pixel electrode in a pixel region defined by intersecting the gate lines and data lines, a TFT for transmitting or intercepting an image signal transmitted through the plurality of data lines to the pixel electrode in response to a scanning signal transmitted from the plurality of gate lines, a transmission gate for distributing the image signal input from an input line to the plurality of data lines, and a repair line intersecting the input line of the transmission gate. Therefore, since the input repair line and the input line of the transmission gate are intersected, a parasitic capacitance occurring between the repair line and the input line of the transmission gate can be reduced.
Abstract:
Devices that include a logic circuit and first and second buffers are provided. The first buffer is spaced apart from the logic circuit by a first distance (and/or is refreshed in a first cycle), and the second buffer is spaced apart from the logic circuit by a second distance that is shorter than the first distance (and/or is refreshed in a second cycle that is different from the first cycle). Moreover, the logic circuit is configured to output, to the first buffer, first data corresponding to fewer toggles than second data that is output from the logic circuit to the second buffer. Methods of operating the devices are also provided.
Abstract:
A display apparatus comprises a first thin film transistor (TFT) and a second TFT which are disposed in a display area. A first signal transmission line is disposed in a peripheral area surrounding the display area and is electrically connected to the first TFT. A second signal transmission line adjacent to the first signal transmission line is electrically connected to the second TFT. In a first portion of the peripheral area, the first signal transmission line is parallel to the second signal transmission line and is spaced by a first gap from the second signal transmission line. In a second portion of the peripheral area, the first signal transmission line is parallel to the second signal transmission line and is spaced by a second gap from and the second signal transmission line. The second gap is greater than the first gap. Other features are also provided.
