An exemplary video wall includes two display panels and a polygonal mullion elimination lens. Each of the display panels includes a main body and a bezel surrounding the main body. The polygonal mullion elimination lens includes a central first concave surface configured to reflect internal light incident thereon, two flat surfaces respectively attached to the main bodies of the display panels, a central second concave surface opposite to the first concave surface, and two lateral surfaces each connecting between a corresponding one of the flat surfaces and the second concave surface. Portions of light emitted by the main bodies of the display panels can enter the mullion elimination lens via the flat surfaces.

A touch panel input stylus comprises a casing, a lens, a shading member, and a light emitting element. The lens, the shading member, and the light emitting element are received in the casing. The shading member defines a stepped through aperture. The stepped through aperture includes a light through hole and a receiving hole having a greater diameter than the light through hole. A longitudinal positioning structure is provided in the receiving hole. The light emitting element is received and fixed in the receiving hole firmly by the longitudinal positioning structure. The longitudinal positioning structure is deformable. The light emitted from the light emitting element passes through the light through hole and then travels through the lens.

A lens system, in order from the object, includes positive first lens, negative second lens, positive third lens, positive fourth lens, and an aperture stop positioned between the third and fourth lens. The second lens includes a first optical portion, a first support portion surrounding the first optical portion with a first surface and second surface. The third lens includes a second optical portion and a second support portion surrounding the second optical portion with a third surface and fourth surface. The fourth lens includes a light stop surface facing the object side of the lens system. The lens system satisfies the formulas: d&#x3c;1.1&#xd7;d, where the dis a distance along the optical axis of the lens system from the second surface to the third surface, and the dis a distance along the optical axis from the fourth surface to the light stop surface.
