    摘要： A console light guide device for use with a control console includes an interconnected light tube array. The light tube array includes a translucent surface, a shaped body substantially surrounding an output connection port on an external face of a console panel, and linear branches arranged relative to the shaped body. Side-firing light-emitting diodes (LEDs) emit light into a corresponding end of the light tube array. An opaque light guard defines a shaped channel and branch channels. The light tube array nests within the opaque light guard such that light from the side-firing LEDs is emitted uniformly through the translucent surface without any internal scattering or bleeding of the light within the console. A control console such as an ophthalmic surgical console is also disclosed herein that includes the console light guide device.

    摘要： A backlight includes a plurality of discrete light sources configured to face a display, and an optical film disposed on the light sources and below and proximate a first plane. The optical film includes a plurality of through-holes extending between first and second major surfaces of the optical film. Each through-hole has a first opening at the first major surface, and a second opening at the second major surface with an open area A2. Each through-hole has length, H, such that H/A2 is greater than or equal to about 0.13. The light from the light sources has a first overall peak intensity in the first plane, and a first brightness uniformity across the first plane, and in the absence of the optical film, the light from the light sources has a second overall peak intensity in the first plane, and a second brightness uniformity across the first plane, such that the first and second overall peak intensities are different by less than about 20%, and the first brightness uniformity exhibits an improvement over the second brightness uniformity by at least 2.8%.

    摘要： A display device includes a display panel, a front light module, and a cover structure. The front light module is located on the display panel. The front light module includes a light guide thin film and a light source. The light guide thin film has a thickness. The light guide thin film includes a top surface and an irregular protrusion structure located on the top surface. The irregular protrusion structure has a stripe feature direction in a plan view, and the irregular protrusion structure has a height difference. The light source is configured to emit a light beam traveling in a direction parallel with the stripe feature direction of the irregular protrusion structure. The cover structure is located on the front light module.

    摘要： A backlight module is applied to providing light to a plurality of keyswitches of a keyboard. Each keyswitch has a keycap and an elastic member abutting against the keycap. The backlight module includes a membrane circuit board and a light guide plate. The membrane circuit board has a light emitting diode corresponding to the keyswitch. The light emitting diode is located at a side of the elastic member and emits light to the keycap. The light guide plate is disposed on the membrane circuit board. The light guide plate has a slot hole for containing the light emitting diode and has a hole corresponding to the elastic member. An optical microstructure is formed on the light guide plate for guiding light of the light emitting diode to be incident to the keycap. The elastic member passes through the hole to be disposed on the membrane circuit board.

    摘要： A backlight module and a display apparatus. The backlight module includes: a back panel, including a base plate and a vertical plate connected with an edge of the base plate; the base plate is matched with the vertical plate to form an accommodation space; a light guide plate, located in the accommodation space and having a safety gap with the vertical plate of the back panel; and an optical film, located in the accommodation space and located on a side of the light guide plate away from the base plate. A surface of the light guide plate facing the optical film has a first positioning portion and a second positioning portion; the first positioning portion positions the optical film in a first direction, and the second positioning portion positions the optical film in a second direction. The first direction and the second direction are perpendicular to each other.

    摘要： Embodiments of this disclosure provide a user input device, such as a gaming controller, for providing input to the information handling system while executing the applications. The user input device may include a three-dimensional lighting structure, which bends across many faces or surfaces of the user input device while providing a uniform light emission. The lighting structure may be used to convey an instruction to a user, such as a direction to turn the device, convey information to the user, such as flashing to indicate a notification, and/or used to convey application feedback, such as flashing or changing lights based on events occurring in the application.
