Provided are a backlight module and a display device. The backlight module includes a back plate, a sealant and a light source portion. The sealant includes a first surface with an inclined angle. The light source portion includes a circuit board and a light source. A first end of the circuit board is disposed on the first surface, and a second end of the circuit board is disposed on the light guide plate. The circuit board is obliquely disposed on the sealant and the light guide plate.

Backlight module and display device

The present disclosure discloses a backlight module including a light guide plate, an optical diaphragm group disposed on a light exiting surface of the light guide plate, and a backlight source disposed at a light incident end of the light guide plate, a middle frame, a radiating fin and a heat conducting connector. The middle frame is disposed on an outer surface of the backlight module and includes a bottom plate and a side wall. The radiating fin is attached to an internal surface of the bottom plate of the middle frame, and the heat conducting connector includes a first portion that contacts the backlight source and a second portion that only contacts a partial region of the radiating fin. The present disclosure also discloses a mobile terminal.

Backlight module and mobile terminal

The present disclosure provides a backlight module, which includes: a transparent light guiding body having a light incidence side surface and a sealed accommodating cavity; a plurality of quantum dots accommodated in the accommodating cavity; and a light source disposed adjacent to the light incidence side surface. The present disclosure also provides a liquid crystal display having the backlight module. The present disclosure prevent the quantum dot material from being affected by moisture and oxygen by sealing the quantum dot materials using glass flat plates, thereby facilitating the display of the liquid crystal display.

Backlight module and liquid crystal display

The present invention provides square seal, a manufacture method of square seal and a manufacture method of a backlight module. The square seal utilizes the roulette design. As being assembled, the redundant material outside the roulette is removed along the roulette to obtain the square seal of narrow frame so that the square seal achieves the narrow frame without the issues of overflow seal and waste material adhesion. The square seal can be easily separated from the waste material to effectively reduce the defect rate. In the manufacture method of the square seal according to the present invention, the square seal inner frame line is first cut on the seal body film material, and then the dotted roulette is formed at position of the square seal outer frame line is pre formed, and finally, the circle of the square seal reserved outer frame line is cut at the periphery of the roulette.

Square seal, manufacture method of square seal and manufacture method of backlight module

A backlight module includes a mold frame, a light guide board, an optic film, a light source, and a heat dissipative sheet. The light guide board has a light incident surface and a light exit surface that is arranged adjacent to the light incident surface. The light source is arranged opposite to the light incident surface of the light guide board. The optic film is attached to the light exit surface. The light source and the light guide board are mounted inside the mold frame. The light source is fixed by a double-sided adhesive tape to the mold frame. The heat dissipative sheet is attached to a surface of the double-sided adhesive tape that is opposite to the mold frame and a projection of the light source is cast to the heat dissipative sheet. A liquid crystal panel and a display screen are also provided.

Backlight module and display screen

The present invention provides a backlight module, including a plastic frame, a light guide plate, a reflective sheet, a backlight lamp and an optical film, wherein the light guide plate and the optical film are sequentially overlapped and disposed on the reflective sheet; the plastic frame surrounds the light guide plate and the optical film, and a peripheral edge of the plastic frame is provided and received with the backlight lamp; the backlight module also includes a quantum dot film; an inner circumferential surface of the plastic frame is provided with a green compensation layer; the backlight lamp is located between a light incident surface of the light guide plate and the plastic frame; the quantum dot film is overlapped on the light guide plate, and is located between the light guide plate and the optical film. A display panel is also disclosed.

A backlight module, a plastic frame and a reflection sheet of the backlight module are disclosed. The backlight module includes a plastic frame and a reflection sheet disposed at a bottom side of the plastic frame. Wherein, the reflection sheet includes a first folding structure; a second folding structure is formed at a bottom portion of the plastic frame; the first folding structure and the second folding structure are complementary and are correspondingly adhered and connected for fixing the reflection sheet at the bottom side of the plastic frame. Accordingly, under a condition without increasing a width of the plastic frame, connection reliability between the plastic frame and the reflection sheet is ensured.

Backlight module and plastic frame and reflection sheet of the same

Related to is a liquid crystal display device, comprising: a liquid crystal display panel; a backlight module including a light guide plate having a light-emitting element, an optical diaphragm group, and a reflective plate; a glass cover covering the liquid crystal display panel and the backlight module, wherein an inner surface of the side wall of the glass cover is in contact with two side portions of the liquid crystal display panel, and two side portions of the backlight module; and a first positioning strip and a second positioning strip, respectively arranged at a top end and a bottom end of the backlight module and are both capable of being engaged with the side wall of the glass cover.

Liquid crystal display

A method for assembling a liquid crystal display includes fixing a liquid crystal panel and a touch panel together to form a touch display screen; inspecting the touch display screen; if no defect is identified in inspecting the touch display screen, fixing the touch display screen and a backlight unit together to form a touch display backlight module screen; and inspecting the touch display backlight module screen. The method for assembling the liquid crystal display helps reduce waste of backlight units and increases yield rate.
