Abstract: A substrate for display device is provided. As a wiring structure of the substrate, the scan line layer and the signal line layer are not connected directly by arranging through-holes between the scan line layer and the signal line layer, but are connected through an ITO layer by arranging through-holes between the scan line layer and the ITO layer and arranging through-holes between the signal line layer and the ITO layer, with an object to reduce the value of the connection resistance between the scan line layer and the signal line layer. Through-holes connecting the scan line layer and the ITO layer and through-holes connecting the signal line layer and the ITO layer are configured in a comb shape respectively and engaged with each other. Thus the length of the ITO connecting the scan line layer and the signal line layer becomes shorter and the value of the connection resistance is reduced.

Abstract: The present invention provides a gamma-correction circuit, which is capable to decrease the noise in graphic signal or make the noise not clearly sensible while carrying out gamma-correction on the graphic signals. In the circuit, a high-pass filter is used to decrease the noise in a graphic signal, a gamma-correction section is used for carrying out gamma-correction on the noise suppressed graphic signal, meanwhile a threshold handling section is used for threshold treatment on the high frequency component of the graphic signal to decrease noise, and then the output of the threshold handling section is combined with the gamma-corrected graphic signal through an adder.

The solution is: the liquid crystal dropped is sandwiched between the TFT substrate and the CF substrate, meanwhile the liquid crystal panel is formed by adhering the light cured seal material disposed at the peripheral area of two substrates.

Abstract: The present invention provides a mounting film for a liquid crystal display drive chip and a method for manufacturing the same. The mounting film is provided with a slit cut from a side edge thereof, or provided with a weakened line for forming the slit. When a distance between a liquid crystal display panel and a control circuit substrate of the liquid crystal display unit is un-uniform, the opening degree of the slit is variable accordingly to accommodate variations in the distance. Such a COF mounting film for a liquid crystal display drive chip may be generally used even though a distance between the liquid crystal display panel and the control circuit substrate varies slightly. Therefore, the manufacturing cost of the liquid crystal display unit may be reduced.

The back side of a liquid crystal panel is set on first concavely curved spacers that support two opposing edges of the panel back side. Second concavely curved spacers are set on the front side of the two opposing panel edges. Third spacers of uniform height are disposed on the panel back side to support it along the remaining two edges. The second spacers are then pressed to pressure the panel from the front side against the first spacers, wherein the panel is clamped between the first and second spacers.
