Abstract: An optical lens, in order from an object side to an image-forming side, includes: a first lens having negative refractive power, a second lens having positive refractive power, a third lens having positive refractive power, a fourth lens having refractive power, and a fifth lens having refractive power. The fourth lens may be positive refractive power, or the fourth lens may have a fourth object-side surface which curves toward the image-forming side. The fifth lens may be negative refractive power, and a spacing may be between the fourth lens and the fifth lens.

Abstract: A light-emitting wireless charging structure includes a base, a wireless charging module, a light-emitting element and an upper cover. The wireless charging module is disposed on the base. The light-emitting element is disposed on the base adjacent to the wireless charging module. The upper cover covers the wireless charging module and the light-emitting element. The upper cover has a lower surface facing the wireless charging module and an upper surface opposite to the bottom surface. When the light-emitting element emits light, light coming from the light-emitting element passes through the upper cover and forms a mark on the upper surface to indicate the position of the wireless charging module. When the light-emitting element is turn off or kept in an off state, either the mark that has been formed on the upper surface disappears therefrom or no any mark is ever shown on the top surface.

Abstract: A display apparatus includes a display monitor and a height adjustment mechanism. The display monitor has a frame with a height adjustment slot. The height adjustment mechanism includes abase fixed in the frame, a sheet structure disposed in the frame in a laterally slidable manner, a sliding plate, and a support stand passing through the height adjustment slot to be connected to the sliding plate such that the frame could be movable relative to the support stand. The sliding plate is slidably disposed in the base and has an abutting structure abutting under the sheet structure. When the frame is located at a high position, the abutting structure and the sheet structure cover the height adjustment slot. When the frame moves to a low position, the support stand relatively moves upward along the height adjustment slot to make the abutting structure push the sheet structure to slide laterally.

Abstract: This present invention provides an optical lens, which includes, in order from an object side to an image-forming side, a first lens group having positive refraction power and a second lens group having negative refraction power. The first lens group comprises a first lens, a second lens, and a third lens. The second lens group comprises a fourth lens, a fifth lens, and a sixth lens. The first lens is a plastic lens, the fourth lens is a convex-concave lens, and the sixth lens is an aspheric lens.

Abstract: A display device includes a display, a base, a flexible circuitry connecting the display to the base, and a support frame assembly disposed between the display and the base. The support frame assembly includes an inner rail connecting to the base, an outer rail connecting to the display, and a first stop member. The outer rail is movably connected to the inner rail so that the outer rail is disposed at a first position or a second position relative to the base. An accommodation space is formed between the outer rail and the inner rail for accommodating the flexible circuitry. The first stop member is disposed between the inner rail and outer rail and extends from the inner rail and away from the accommodation space for restricting the outer rail to move along the inner rail between the first position and the second position.

Abstract: This invention provides an optical lens, in order from an object side to an image-forming side, comprises a first lens with positive refraction power; a second lens with negative refraction power; a third lens with positive refraction power; a fourth lens with negative refraction power; a fifth lens with positive refraction power and a sixth lens with negative refraction power. The optical lens satisfies the following conditions: 0.50?EFL/TTL, EFL/TTL?1.00, 0.65?F123/EFL, and/or F123/EFL?1.00.
