7. The method according to claim 4, wherein, with said period, said overdriving voltage is reduced to an appropriate lower level when the grey level of said pixel overshoots above said target grey level and said row of said LEDs is turned off.
8. The method according to claim 7, wherein said appropriate lower level is equal to the driving voltage corresponding to said target grey level of said pixel within said period.
9. A method for driving a display device having a direct-lit backlight module having a plurality of LEDs as light source arranged in a plurality of horizontal rows where said display has a panel positioned in front of said backlight module, said panel has a plurality of horizontal scan lines and a plurality of vertical data lines, the intersection of a said scan line and a said data line defines a pixel of said panel, said pixel is turned by enabling said scan line, supplying a driving voltage on said data line, and turning on a row of said LEDs behind said pixel, said pixel has a retardation property with which the grey level of said pixel gradually approaches the grey level corresponding to said driving voltage, said method comprising the steps of:
within an initial portion of the period of a frame, applying an overdriving voltage to said pixel that is larger than the voltage corresponding to a target grey level of said pixel within said period and then, with the remaining portion of said period, applying a driving voltage to said pixel that is equal to the voltage corresponding to said target grey level of said pixel; and
within said period, applying a control signal whose frequency is at least equal to the frame rate of said display device so that, during at least a portion of the process where the grey level of said pixel is approaching said target grey level, said row of said LED is turned off.

11. The method according to claim 9, wherein the frequency of said control signal is twice of the frame rate of said display device.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A therapeutic treatment method in a patient having suppressed immune function resulting from human immunodeficiency virus (HIV) infection, comprising the steps of:
(a) infusing a dose of one or more monoclonal antibodies (mbAs) each of which specifically bind to an LFA-1 binding site to thereby inhibit overproduction of LFA-1 on CD8 cells in the patient’s bloodstream, the LFA-1 binding site selected from a group of LFA-1 binding sites consisting essentially of alpha () chain binding sites and beta chain () binding sites, wherein the dose is between about 0.1-1.0 milligrams of said one or more monoclonal antibodies per kilogram of the patient’s weight; and
(b) repeating said infusion as necessary.
2. A method for treating a patient having suppressed immune function resulting from human immunodeficiency virus (HIV) infection in order to reduce the overproduction of CD8 cells in said patient, comprising the steps of:
(a) infusing a dose of a monoclonal antibody selected from a group consisting of monoclonal antibodies that specifically bind to LFA-1 binding sites and LFA-1 binding sites, said dose being between about 0.1-1.0 milligrams of said monoclonal antibody per kilogram of the patient’s weight; and
(b) repeating said infusion as necessary.
