Backlight module and display panel
The present disclosure relates to the field of display technology and, in particular, to a backlight module and a display panel. The backlight module may include a backplane, an optical film, and a light emitting plate. The backplane includes a bottom plate, a first side plate, and a second side plate, where the first side plate and the second side plate are arranged at two opposite sides of the bottom plate in a first direction, and both have support parts protruding toward an inner side of the back board. The optical film is arranged on a side of the support part away from the bottom plate, and has two opposite ends supported on the support parts. The light emitting part is arranged on the bottom plate and positioned at a side of the support part facing the bottom plate, and a light emitting direction of the light emitting part is toward the optical film.
Horticulture light panel assembly
A system and method for a light panel assembly which is particularly useful for commercial horticultural applications. An extruded heat sink frame provides for a layered light panel assembly with superior heat dissipation characteristics and low power requirements while providing highly efficient returns and output radiant flux.
DISPLAY APPARATUS
The present invention relates to a display apparatus that does not include a middle mold and a rear chassis, and is capable of supporting an internal configuration of a display apparatus such as a display panel and a light guide plate with only a front chassis and a rear cover. It is possible to effectively dissipate heat by including a separate heat sink. In addition, heat generated from the electrical component substrate can be dissipated through the plate coupled to the electrical component substrate, the electromagnetic wave can be shielded, and the heat sink and the plate can be connected to improve the heat dissipation and electromagnetic wave shielding efficiency.
Light guide structures for display backlights
An electronic device may have a display with backlight structures. The backlight structures may produce backlight that passes through the display layers in the display. The backlight structures may include a light guide plate that distributes light across the display layers. A light source such as a light-emitting diode light source may be used to provide light to the light guide plate. The light source may overlap an edge portion of the light guide plate. A light guide structure having a bend may be coupled between the light source and the light guide plate. The light guide structure may be used to guide the light from the light source to the light guide plate via total internal reflection. A light guide structure may be provided with light leakage promotion structures to evenly distribute light from a centralized light source along the edge of a light guide plate.
MOBILE TERMINAL AND METHOD FOR CONTROLLING THE SAME
A mobile terminal according to the present disclosure may include a body, a light-emitting device provided within the body, a display unit disposed on a front surface of the body, and a corner region of which is formed in a curved surface, and a light guide plate disposed at a lower side of the display unit to guide light emitted from the light-emitting device to the display unit, and formed with a chamfer surface at a corner region facing the curved surface, wherein the light-emitting device is disposed adjacent to the chamfer surface to emit light toward the chamfer surface.
Light source device and display apparatus
Provided are: a light source device capable of preventing light from a light source disposed to face an end surface of a light guide plate from leaking to a side in which the light guide plate emits the light without providing a new member; and a display apparatus including the light source device. A light source unit 2 is disposed to face an end surface of a light guide plate 3, and a heat spreader supporting the light source unit 2 has a shape of covering the light source unit 2. A light from the light source unit 2 is irradiated to the end surface of the light guide plate 3, as well as the protrusive plates 71 and 72 side of the heat spreader. Since the light irradiated to the protrusive plate 71 side is shielded by the protrusive plate 71, the light does not leak to a panel chassis 5 side.
FLAT PANEL LIGHTING APPARATUS
A flat panel lighting apparatus, which makes it easy to replace a circuit board with LEDs thereon, is provided. The flat panel lighting apparatus includes a backplate, a driving unit, a light guide plate, a frame, a bracket, a circuit board, a connector and a cable connecting the driving unit and the circuit board. The frame with an opening portion is disposed at an outer periphery of the backplate and the light guide plate. The bracket is detachably coupled to the opening portion of the frame. The circuit board with light sources, is disposed in a space between the frame and the light guide plate, and is replaceable in a sliding type through the opening portion of the frame when the bracket is decoupled from the frame. The connector has a female terminal attached to the circuit board and a male terminal detachably coupled to the female terminal.
Backlight module, method of manufacturing same, and display device
A backlight module, a method of manufacturing the same, and a display device are provided. The backlight module includes a case provided with a via hole; and a flexible circuit board disposed in the via hole and having a size matching a size of the via hole.
BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE
A backlight module, including a light guide plate and a flexible circuit board, wherein an edge of the light guide plate is provided with plural light source mounting holes disposed along a thickness direction of the light guide plate; a light source is mounted in every light source mounting hole in such a manner that a light emitting surface of the light source is attached onto a hole wall of the light source mounting hole; plural groups of anode-cathode conductive parts are disposed on the flexible circuit board in one-to-one correspondence with the plural light source mounting holes, each being connected to an anode and a cathode of the light source in a corresponding light source mounting hole. The backlight module improves the brightness and uniformity of the light entering the light guide plate. A liquid display device including the above-mentioned backlight module is further provided.
Film-based lightguide with adhered component between fold region and extraction region
A device comprises a film with an adhesive layer on a first side of a core layer, a major sheet area of the film bounded by edges of the film with a light extracting region positioned to receive and extract light propagating by total internal reflection within the core layer out of the major sheet area, and a minor sheet between the major sheet area and an array of strips. The strips extend from the minor sheet area of the film, and each strip of the array of strips is folded within a fold region and stacked. The device further comprises a component extending a width of the array of strips where they extend from the minor sheet area, wherein the adhesive layer adheres the component to the film between fold region and the light extracting region. In some embodiments, the adhesive layer is a cladding layer.
