A display apparatus includes an image display panel, a light source device, and a control device. The light source device includes a light source that emits light and a light guide member arranged on the back surface side of the panel as seen from the display surface, receives the light via its side surface with respect to its surface facing the panel, and has divided areas arranged in a direction in which the light travels. Each area includes a light modulation layer brought in a light transmission state or in a light scattering state. The control device brings the layers in the scattering state in respective scattering control periods temporally different from each other. When bringing a light modulation layer in the scattering state, the control device controls the light source device with a drive pattern based on a distance between the side surface and the corresponding area.

The device includes a casing having a front wall; apertures on the front wall; a backlight assembly in back of the front wall within the casing; and a light pipe structure to receive light from backlight assembly. The light pipe structure includes plurality of light pipes in which the light pipes have a lower vertical body portion, an upper horizontal body portion, and a central body portion between the lower vertical body portion and the upper horizontal body portion; and a bracket that connects and supports the light pipes in which the bracket is generally planar. The bracket has broad support regions that connect to a back portion of each of the light pipes and a narrow bridging region between broad support regions in which the support regions are broader than the narrow bridging region in the vertical dimension.

A backlight unit includes a backplane and a light guide plate. The backplane includes a body section and a bending section connected with the body section; the body section includes a first surface and a second surface opposite to each other; the bending section includes at least a connecting portion and a mounting portion extended from the connecting portion and opposite to the first surface; the connecting portion is a bending structure along a first side of the body section; a bending direction of the connecting portion is a direction from the second surface of the body section to the first surface; the light guide plate is disposed on the first surface of the body section; one side of the mounting portion away from the connecting portion is opposite to a first end face of the light guide plate; and light sources are disposed on the mounting portion. A display device is further disclosed.

The present disclosure provides a backlight module, a method for assembling the same, and a display panel. The backlight module includes: a back plate; a light bar arranged on the back plate; a light guide plate arranged on the back plate to form a gap between the light guide plate and the light bar; a film structure arranged on a light-exiting surface of the light guide plate opposite to the back plate; and a protruding part disposed in the gap, wherein opposite sides of the protruding part are in contact with at least a portion of the light guide plate and the film structure and at least a portion of the light bar respectively.

Provided is a circuit board including: a support substrate; a plurality of light emitting devices mounted on the support substrate; and a device protection portion surrounding one of the light emitting devices, or three or more surfaces of the plurality of light emitting devices.

The inventive concepts provides a liquid crystal display having advantages of being capable of simplifying a manufacturing method thereof and minimizing damage to internal components therein by using a bottom chassis in which a flange unit and a receiver of a backlight unit are separated from each other. In accordance with the inventive concepts, the bottom chassis is formed in such a shape so as to be assembled and disassembled. Accordingly, it is possible to securely couple the flange unit to any necessary portions of the receiver, thereby reducing an effort and cost for mold development. Further, a gap between the receiver and the flange unit is formed to provide a predetermined degree of flexibility. Therefore, when the display device is assembled, deformation of the entire bottom chassis caused by deformation of the flange unit may be prevented.

The present invention provides an optical film assembly mounting structure, which includes: a first mold frame (6), a second mold frame (8) arranged on the first mold frame (6), and an optical film assembly (9) arranged between the first and second mold frame (6, 8). The first mold frame (6) carries the optical film assembly (9) thereon and the second mold frame (8) is positioned on and presses down the optical film assembly (9) so as to achieve secure mounting of the optical film assembly (9). The first mold frame (6) includes an inclined first upper surface (61). The second mold frame (8) includes a first bottom surface (81) and a second bottom surface (83) connected to the first bottom surface and having an inclination angle identical to that of the first upper surface (61). The optical film assembly (9) is positioned on the first upper surface (61) and the first and second bottom surfaces (81, 83) are positioned on and press down the optical film assembly (9).
