Abstract:
In a display panel and a display apparatus having the display panel, the display panel includes array and opposite substrates. The array substrate includes display and peripheral areas. Gate and source lines are formed in the display area. A gate driving part and first and second clock lines are formed in the peripheral area. The gate driving part outputs gate signals to the gate line. The first and second clock lines respectively transmit first and second clock signals to the gate driving part. The opposite substrate is combined with the array substrate and includes a common electrode layer. The common electrode layer has an opening portion patterned to expose the first and second clock lines. The exposed portions of the first and second clock lines have substantially the same area. Thus, delays of the gate signals may be minimized and distortion of the gate signals may be prevented.

Abstract:
Gate-driving circuitry of a thin film transistor array panel is formed on the same plane as a display area of the transistor array panel. The gate-driving circuitry includes driving circuitry and signal lines having apertures. Thus, a sufficient amount of light, even though illuminated from the thin film transistor array panel side, can reach a photosetting sealant overlapping at least in part the gate-driving circuitry. The thin film transistor array panel and the counter panel are put together air-tight and moisture-tight. Consequently, the gate-driving circuitry can avoid corrosion by moisture introduced from outside. Gate-driving circuitry malfunctions can also be reduced.

A display panel includes an amorphous silicon gate driver in which a lower voltage than the gate-off voltage output from the gate driver is applied to an adjacent stage as a low voltage transmission signal.
Abstract:
A gate driver includes multiple stages. Each stage has a circuit portion and a wiring portion. The wiring portion delivers first and second clock signals to the circuit portion. Further, the wiring portion includes first and second clock wirings receiving the first and second clock signal, respectively, first connecting wirings electrically connecting the first clock wiring with a first every other stage, and second connecting wirings electrically connecting the second clock wiring with the odd-numbered stages. Further, the wiring portion includes third connecting wirings electrically connecting the first connecting wiring with a second every other stage and fourth connecting wirings electrically connecting the second connecting wiring with the even-numbered stages. This configuration may prevent the gate driver from operating erroneously and reduce power consumed by the gate driver.
Abstract:
Provided is a method of recycling waste scagliola, which includes a pre-treating step, a pyrolysing step, a resin recycling step, and a filler recycling step. The pre-treating step includes storing the waste scagliola of a dry dust type, drying and storing the waste scagliola of a wet dust type, or pulverizing and storing the waste scagliola of a scrap type. The pyrolysing step includes receiving and heating a recycling raw material stored in the dust or granular type in the pre-treating step, and decomposing the raw material into a resin mixed gas and a filler mixed solid material. The resin recycling step includes receiving the resin mixed gas decomposed in the pyrolysing step, and recycling a resin from which impurities are removed by a purifying process. The filler recycling step includes receiving the filler mixed solid material decomposed in the pyrolysing step, and recycling a filler from which impurities are removed by a firing process. Thereby, the resin and filler are more effectively recycled from the waste scagliola, so that it is possible to prevent environmental pollution caused by disposing the waste scagliola, and to enhance an effect of reducing resource waste according to resource recycling.
