| 20080246907 | METHOD FOR PROVIDING IMPROVED DISPLAYING EFFECT OF LIQUID CRYSTAL PANEL IN OPERATION TEMPERATURE RANGE THEREOF - A method for providing an improved displaying effect of a liquid crystal panel is provided, wherein the liquid crystal panel comprises two alignment layers disposing therebetween a liquid crystal layer having a spiral pitch and a liquid crystal twist angle. The method comprises steps of (a) spacing the two alignment layers at an interval with a desired twist angle therebetween; (b) measuring a first ratio of the interval to the spiral pitch of the liquid crystal layer, at which the liquid crystal twist angle is less than the desired twist angle between the two alignment layers; and (C) deciding an initial ratio of the interval to the spiral pitch of the liquid crystal layer being larger than the first ratio for providing the improved displaying effect of the liquid crystal. | 10-09-2008 |

| 20110128028 | PROBE CARD, MAINTENANCE APPARATUS AND METHOD FOR THE SAME - A maintenance apparatus and a maintenance method for a probe card are provided. The maintenance apparatus includes a first supporting member, a second supporting member, a first clamping member, a second clamping member, and a plurality of locking units. In the maintenance method, the first supporting member and the second supporting member are initially positioned underneath below the two sides of a positioning slice, respectively, and then the first clamping member and the second clamping member are each disposed on the first supporting member and the second supporting member, respectively. First clamping member and first supporting member, and second clamping member and second supporting member are secured together respectively by locking units. Thus two sides of positioning slice are secured tightly and the positioning slice is well fastened. A probe card is also provided. The probe card includes a guide slot having a size corresponding to that of maintenance apparatus. | 06-02-2011 |
