A method of making the optical combiner lens and a wearable heads-up display including the optical combiner lens are disclosed.

Display device and backlight module

Disclosed are a display device and a backlight module. The display device includes a backlight module, a liquid crystal display panel, and a chip-on-flex. The backlight module may include a frame body, and an edge-type light source, a light guide plate, a reflector strip, a light absorber strip, and an optical film disposed in the frame body. The light absorber strip and the diffuser sheet are not bonded, and the reflector strip and the diffuser sheet of the optical film are bonded.

BACKLIGHT MODULE AND DISPLAY DEVICE

The disclosure relates to a backlight module and a display device. The backlight module includes: a conductive adhesive tape configured for adhering the backlight module to a display panel to transfer electrostatic charges in the display panel to the backlight module; and a first wire configured to lead the electrostatic charges out from the backlight module, the electrostatic charges led out from the backlight module at least including the electrostatic charges transferred from the display panel to the backlight module, electrostatic charges generated in the backlight module, or a combination thereof. Electrostatic charges in the display panel are led into the backlight module through the conductive adhesive tape, and are led out via the first wire of the backlight module, so that no wire needs to be provided in the display panel for leading out the electrostatic charges, that is, it is not necessary to adjust wirings in the display panel.

THIN FLAT PANEL LED LUMINAIRE
20170307801 · 2017-10-26 · ·

The invention described herein is a very thin flat panel LED luminaire, including a flat baseboard, a flat reflection panel, a flat acrylic panel, a flat diffusion panel, LED bar, and aluminum encasement frame which combines with the baseboard to form the chassis for the luminaire. The LED bar is placed along either or both sides of the stack. The acrylic panel is printed with a mesh-like mask pattern of dots in a pattern in which the density of the pattern is decreases the farther away from the LED bar the pattern is, differentially coupling the light from the point source LED bar from the reflection panel into the flat acrylic panel so that illumination across the luminaire is substantially uniform.

Personal digital assistant apparatus

An information processing apparatus including a display portion; a backlight unit configured to irradiate light from a rear face side of the display portion; a rear frame having height equivalent to at least a thickness of the backlight unit, and configured to protect the backlight unit; and an outer circumference casing attached to the rear frame, or formed integrally with the rear frame, and provided along an outer circumference of the display portion.

LED panel light

NEON-FREE ILLUMINATED SIGNAGE
20170294152 · 2017-10-12 ·

A system and method for presenting a visual message by illumination. The system includes an LED light source and a transparent sheet. The transparent sheet is a transmission medium that includes a modified surface that refracts light in designated areas. The LED source illuminates the transparent sheet so that the LED illumination of the sheet achieves a visual effect of a neon filled glass tube lighting. The illumination system, however, is neon-free. The modified surface includes a disruption pattern or a printed ink layer, or the sheet includes two modified surfaces, one modified with a disruption pattern and another one modified with a printed ink layer. The LED light source includes multiple LED emitters on a circuit board. The LED light source projects light through the sheet in a direction that is parallel to a surface plane of the sheet.
