Abstract: The present invention provides a backlight module and a liquid crystal display device. The backlight module of the present invention includes an upper brightness enhancement film (7), which includes a central zone (71) and a lens zone (72) located between the central zone (71) and a mold frame (1). The upper brightness enhancement film (7) includes a prism structure formed on an upper surface of the central zone (71); and the upper brightness enhancement film (7) includes a lens structure formed on an upper surface of the lens zone (72). The lens structure includes a plurality of concave surfaces (721) arranged in sequence in a side-by-side manner from an edge of the upper brightness enhancement film (7) toward interior thereof. The prism structure and the lens structure of the upper brightness enhancement film (7) are integrally formed together. The lens structure of the upper brightness enhancement film (7) helps diverge light projecting outward so as to have a part of the light extending over and covering a portion of an area shielded by the light-shielding tape (8), expanding a view area of the backlight module to thereby achieving a visual effect of narrowing bezel. Further, the manufacturing process is simplified, the manufacturing cost is reduced, and product yield is increased.

Abstract: The present invention discloses a backlight module and a liquid crystal device (LCD). The backlight module includes a LED component, a light guiding plate, a quantum dot (QD) layer, and a graphite sheet. The QD layer is arranged between the LED component and the light guiding plate, and the QD layer is arranged on the graphite sheet. By configuring the QD layer on the graphite sheet, the QD layer is prevented from being failed due to high temperature so as to extend the life cycle of the QD layer. Thus, the display performance may be enhanced.

Abstract: A quantum dot backlight module is disclosed. The quantum dot backlight module comprises a light source; a quantum dot layer, which emits fluorescence after being excited by light that is emitted by the light source; and a light guide plate, which guides the fluorescence that is emitted by the quantum dot layer to a needed direction, wherein the quantum dot layer is arranged on a light-entering side of the light guide plate, and a colloid layer is arranged between the light source and the quantum dot layer so as to enable the light source and the quantum dot layer to be bonded with each other closely, whereby the light source, the quantum dot layer, and the light guide plate are assembled together. According to the present disclosure, the light transmission mode of the light source after entering into the light guide plate is changed through changing the structure of the quantum dot backlight module, so that the light loss thereof can be reduced, and the light-emitting efficiency of the backlight module can be improved.

Abstract: A display device is provided, which includes a middle frame, a first substrate, a second substrate, a cover plate, an ink layer, and a silicone glue. By providing a barrier block or a slot disposed on a side of the ink layer close to the first substrate, the barrier block is disposed between the silicone glue and a side frame to prevent the ink layer on the cover plate from spreading of a pollution source, so that a surface of the ink layer of a glass cover plate of a display module can meet dyne specification requirements. It also ensures an adhesive strength of the middle frame and the cover plate to prevent bonding failure.
