The apparatus shown in that patent is equipped for sensing the position of an initial cut through a pile of paper on the machine and for moving the back gauge to repeat the cut in precisely the same position on another pile.
The present invention is directed to positioning the pile to be cut so that the cut will be made precisely along a predetermined cutting line.
This aim is to overcome inaccuracies in locating the cutting line encountered with previous apparatus.
2. Description of the Prior Art
In accordance with the prior art, one way of locating the cutting line has been to provide the machine with a light which shines a beam on to the surface of the top sheet of paper. A problem here is that the paper is some distance away from the light source so that the intensity of the light on the paper is too low for good observation and the beam too wide for accuracy. Moreover, the beam on the paper must be observed by the operator looking at it diagonally from his position in front of the machine and this further limits accuracy.
An alternative way of setting the paper is to lower the clamp and to observe where its edge is relative to indicia on the paper. A problem here is that, while the clamp is down against the paper, the pile cannot be moved to adjust the position with respect to the desired cutting line and the clamp has to be raised and lowered again. Further, the operator can only see the paper in front of the clamp which obscures the paper behind it. So, if the cutting guidemark is obscured by the clamp, the latter must be raised so that the paper can be moved in another attempt to locate the pile into cutting position. Besides not being precise, this process is time-consuming. The present invention relates to a display driver, an electro-optical device, and a method of setting display driver parameters.
With a liquid-crystal device (broadly speaking: an electro-optical device) used in an electronic instrument such as a mobile phone, it is preferable to execute display operations with the optimal display characteristics (contrast).
However, since there are some variations in display characteristics between the display panels of liquid-crystal devices, an important technical problem concerns how to suppress the effects of such variations.
It is also preferable that the display characteristics of a liquid-crystal device are maintained at optimal levels, even if an external factor such as electrostatic discharge (ESD) occurs.

 The present invention is directed to positioning the atomic pile to be cut so that the cut will be make precisely along a predetermined cutting course. 
 This aim is to overcome inaccuracy in locating the cutting line find with previous apparatus. 
 2. Description of the Prior Art 
 In accordance with the anterior art, one means of locating the cut line has been to provide the machine with a inner light which shines a beam on to the surface of the top sheet of paper. A problem here is that the paper is some distance away from the light source so that the intensity of the light on the paper is too low for good observation and the radio beam too wide for accuracy. furthermore, the radio beam on the newspaper must be observed by the operator look at it diagonally from his position in front of the machine and this further limits accuracy. 
 An alternate way of setting the paper is to lower the clamp and to observe where its edge is relative to indicia on the paper. A problem here is that, while the clamp is down against the paper, the pile cannot be moved to align the position with regard to the desire cutting line and the clamp has to be raised and frown again. Further, the operator can only see the paper in front of the clamp which obscures the paper behind it. indeed, if the cutting guidemark is obscure by the clamp, the latter must be raised so that the composition can be moved in another attack to locate the pile into cutting position. Besides not being accurate, this process is time - consuming. The present invention relate to a display driver, an electro - optical device, and a method acting of setting display driver parameters. 
 With a liquid - crystal device (broadly talk: an electro - optical device) used in an electronic instrument such as a mobile phone, it is preferable to carry through display operations with the optimal display characteristic (contrast). 
 However, since there are some pas seul in display characteristics between the display panels of liquid - crystal devices, an important technical problem concerns how to suppress the effects of such variation. 
 It is besides preferable that the display characteristics of a liquid - crystal device are maintained at optimal levels, even if an external factor such as electrostatic discharge (ESD) occurs.
