Abstract: The present invention discloses a display including a display panel and a light redirecting film disposed on the viewing side of the display panel. The light redirecting film comprises a light redistribution layer, and a light guide layer disposed on the light redistribution layer. The light redistribution layer includes a plurality of strip-shaped micro prisms extending along a first direction and arranged at intervals and a plurality of diffraction gratings arranged at the bottom of the intervals between the adjacent strip-shaped micro prisms, wherein each of the strip-shaped micro prisms has at least one inclined light-guide surface, and the bottom of each interval has at least one set of diffraction gratings, and the light guide layer is in contact with the strip-shaped micro prisms and the diffraction gratings.

Abstract: A tool device includes a lever having two screw holes, two arms each having an upper orifice for securing to the end portions of the lever, two rods attached to the arms for positioning two end ears of a housing of a universal joint to the arms, one or more screws engaged with the screw holes of the lever and adjustable relative to the lever, and each screw include a lower cavity for engaging with a stud, each stud include a tip for engaging with the slot that is formed between the end ears of the housing and for being forced to engage into the slot and to separate the end ears of the housing from each other and for allowing a bearing member to be removed from the housing.

Abstract: A tool device includes a support lever having a middle screw hole and having two side open channels, a pressing member having an outer thread for engaging with the screw hole of the support lever and having a center member pivotally attached to the inner end portion for engaging with the object, and two connecting levers each having a tongue formed in an inner end portion for engaging with the bearing element to be removed and each having an outer end portion engageable into the channel of the support lever, and each having an enlarged head for anchoring the support lever to the element and the object, and for allowing the element to be pulled and removed from the object with the pressing member.

Abstract: A tool device includes a support lever having two screw holes, a pressing lever, an adjusting member is threaded with one of the screw holes and pivotally coupled to the middle portion of the pressing lever, and a pressing member is threaded with the other screw hole of the support lever and has an end portion for engaging with a rear portion of the pressing lever, a holding member is attached to the support lever and includes a front portion having an opening, and a retaining member is changeably attached to the support lever for engaging with the holding member and for selectively engaging or retaining the ball joint or universal joint between the retaining member and the pressing lever.
