A tray module includes a tray in which a plurality of display device components are alternately stackable with a plurality of protective sheets. Each of a protective sheet among the plurality of protective sheets includes: a first polymer layer including a first polymer resin which is foamed, and top and bottom surfaces opposite to each other; a second polymer layer on each of the top and bottom surfaces of the first polymer layer, the second polymer layer including a second polymer resin; and a paper layer defining an outer surface of the protective sheet.

A connector assembly for connecting a first electrical component to a second electrical component includes a circuit board which is electrically conductively connectable to the first electrical component. A plug unit is electrically conductively couplable, at a plug end, to a mating plug unit and is disposed on a first side of the circuit board. A light source is disposed on a second side of the circuit board opposite the first side. A light guide has an in-coupling region and an out-coupling region, and a through-hole in which the plug end of the plug unit is at least partially disposed. The light guide also has a light injection opening in which the light source is at least partially disposed. The in-coupling region is disposed on a side wall of the light injection opening, and the out-coupling region surrounds the through-hole.

The backlight module includes the following units. Multiple first light emitting units are disposed on a top surface of a transparent substrate. A beam angle of the first light emitting units is greater than or equal to 30 degrees and less than or equal to 45 degrees. Multiple second light emitting units and a light guide plate are disposed on a bottom surface of the transparent substrate. Each second light emitting unit is disposed in a respective hole of the light guide plate. A light intensity of the first light emitting units in a first mode is smaller than that in a second mode. A light intensity of the second light emitting units in the first mode is greater than that in the second mode. In this way, the purpose of privacy protection can be achieved.

Various light fixtures are provided for mounting within and below suspended grid ceilings incorporating T-bars and ceiling panels. The light fixtures comprise a double or single edgelit planar or wedge shaped optical element that functions simultaneously as an outcoupling TIR light guide and a light scatterer or direct throughput lens. It provides a number of benefits because of its edgelit design including; thin forms and shallow depth, extended emitting area and controlled lighting distributions from one or two light guide faces. Additionally, areas typically dedicated to bezels or edge reflectors can be greatly reduced or eliminated due to decreased hotspotting to provide a fixture face with very high percentage of light emitting area. Embodiments are described for direct, indirect, and direct indirect configurations. The embodiments provide increased light output, uniformity of brightness and color and controlled direct and indirect lighting distributions and with single or dual off axis intensity peaks. Such light distributions are particularly useful in applications such as direct illumination of offices, schools, hospitals, retail or commercial spaces and table tops or work surfaces or indirect illumination of ceilings, wall washing and surface area lighting as well as other lighting applications.

Embodiments of the present disclosure provide a light-emitting table top. The table top includes a light source assembly, a light guide board, a plastic thin film and a pattern layer, wherein the light guide board is arranged on a light exit side of the light source assembly; the plastic thin film covers a side surface of the light guide board away from the light source assembly; and the pattern layer is printed on the light guide board and/or the plastic thin film, so that a table top displays a light-emitting effect of a predetermined pattern.

A keyboard includes a base plate, a plurality of keys and a backlight module. The base plate has a short axis direction and a long axis direction. The keys are disposed on the base plate along the long axis direction, and the keys are arranged to form a plurality of rows. The backlight module is disposed on the base plate and includes a shielding sheet, a light guide plate and a reflecting sheet. The light guide plate is disposed on a lower surface of the shielding sheet. The light guide plate includes a plurality of long openings, and each of the long openings has at least one long side. The long side is parallel to the long axis direction, and each of the long openings has a central axis. The central axis is located between two adjacent rows on which the keys are disposed.

A display device includes a panel, a backlight, and an adhesive tape. The backlight is placed under the panel. The adhesive tape has a light blocking property and is bonded to an end face of the panel and the backlight.

A backlight source module and a display device are provided. The backlight source module includes a back plate structure and a rubber member. The back plate structure includes a bottom plate, and a first side plate and a second side plate respectively connected with the bottom plate, and the first side plate and the second side plate oppose each other. A light-emitting portion, a light-guiding component and the rubber member are sequentially disposed on the bottom plate along a first direction pointing from the first side plate to the second side plate. The rubber member is only disposed at the second side plate.

An electronic device is provided. The electronic device includes: a device body, a display module, a backlight module, and a fingerprint identification assembly. The display module is disposed on a surface of the device body. The backlight module includes a bearing frame and a light guide assembly. The bearing frame is fixedly disposed in the device body. The bearing frame is provided with a first through hole. The light guide assembly is disposed on the bearing frame. A first gap is formed between the light guide assembly and the display module. The fingerprint identification assembly includes a transmitter and a receiver. The transmitter is disposed in the first gap. The receiver is disposed on a side of the bearing frame away from the light guide assembly and is corresponding to a position of the first through hole.

The present disclosure provides a display panel, a method for manufacturing a display panel and a display device. The display panel includes a back frame, a backlight module and a panel, where the backlight module and the panel are arranged in the back frame, the back frame includes a back plate, and the back plate is provided with a hollow-out area. The backlight module is arranged between the back plate and the panel and includes a light transmissive area and a light emitting area, and the light transmissive area corresponds to the hollow-out area. The panel is arranged on a side of the backlight module away from the back plate, and includes a display area and a transparent area, where the display area corresponds to the light emitting area, and the transparent area corresponds to the light transmissive area.
