Abstract:
A light-guide plate includes a body for guiding incident light, and at least an inserting portion penetrating a portion of the body, wherein at least a light source for providing the light-guide plate with the light is inserted into the inserting portion. The inserting portion can be formed at an end portion of the body. A side surface of the body can be recessed to form the inserting portion. A light-diffusing pattern can be formed at a side surface of the inserting portion, and the side surface of the inserting portion is substantially parallel with the side surface of the body.
Abstract:
A backlight assembly, usable in a display device, includes a plurality of light sources and a light guiding plate guiding light emitted from the light sources, wherein the light sources are arranged corresponding to a side of the light guiding plate and the side includes a central portion. The light sources include first light sources as a first group arranged on the central portion of the light guiding plate, and second light sources as a second group adjacent to the first group, wherein a pitch of the first light sources is smaller than a pitch of the second light sources.
Abstract:
A light illuminating unit includes light generating members and a light guiding plate. Each of the light generating members generates light. The light generating members include an LED. The light guiding plate includes a light-incident face onto which the light is incident, a lateral face facing the light-incident face, and a light-exiting face through which the incident light exits. The light-exiting face being configured to connect the light-incident face and the lateral face. An interval between the light-incident face and the lateral face varies in accordance with a position of each of the light generating members. Thus, a number of LEDs decreases, so that an assembly process of the light illuminating unit may be simplified, and manufacturing cost and power consumption thereof may be reduced.
Abstract:
An illuminating device in which one or more chamfer surfaces are formed at one or more corner portions, respectively, of a light guiding part, and a luminous body is disposed corresponding to a chamfer surface, and a display apparatus using the illuminating device are disclosed. The illuminating device has the light guiding part for guiding light to a display unit of the display apparatus and a light source part. The light guiding part includes an incident surface on which the light is incident, a back surface opposite to the incident surface, an emitting surface from which the light is emitted to the display unit, side surfaces perpendicular to the incident surface and the emitting surface, and chamfer surfaces formed at corner portions, respectively, each connected to the incident surface and one of the side surfaces. The light source part includes marginal luminous bodies each corresponding to each of the chamfer surfaces. The light source part may further have at least one central luminous body that corresponds to the incident surface.
Abstract:
The present invention relates to a high energy density beam welding system using molten metal droplet jetting. The present invention includes a beam emitting unit for emitting a high energy density beam onto a welded portion on a target object; and a molten metal droplet jetting unit for generating molten metal droplets to transfer or spray the molten metal droplets onto the welded portion on the target object, which follows a path of the beam emitting unit. Thus, it has advantages of widening a range of applications and enhancing the productivity and the quality in that a welding can be performed at a high junction efficiency even where a gap is wide, a loss in the high density energy beam is small, and heat distortions of the welded portion can be minimized.
Abstract:
A display device including a case including a front case and a rear case, a main display panel and a sub display panel disposed inside the case, a protective member disposed on a front surface of the main display panel and protecting the main display panel, and a support frame disposed inside the case and supporting both the display panel and the protective member. The support frame includes a first support part contacting a lower surface of the main display panel and a second support part supporting a lower surface of the protective member.
Abstract:
A backlight assembly includes a light source providing light, a mold frame receiving the light source unit and a bottom chassis. The bottom chassis includes a bottom plate, sidewalls extending from the bottom plate and an extension part bent from at least one of the sidewalls and overlapping an adjacent sidewall. The mold frame and the bottom chassis are integrally formed. The extension part overlaps the adjacent sidewall at a corner of the bottom chassis. Thus, the torsional strength of the bottom chassis and a backlight assembly having the bottom chassis is improved. The torsional strength is maintained when a backlight assembly is manufactured.
Abstract:
A light guide unit for a point light source includes a light incident portion, a first reflecting portion and a second reflecting portion. The light emitted from the point light source enters to the light incident portion. The light incident portion includes an optical pattern diffusing an incident light corresponding to the point light source. The first reflecting portion reflects a first light of the incident light. The second reflecting portion roundly connects the first reflecting portion to the light incident portion and reflects a second light of the incident light.
Abstract:
A display device including a display panel displaying images, a protective member disposed on a front surface of the display panel and protecting the display panel and a support frame supporting both the display panel and the protective member The support frame includes a guide part protruded in a direction perpendicular to a plate surface of the protective member and fixing the protective member such that the protective member is prevented from moving in a direction parallel to the plate surface. The support frame is adhered to edges of the protective member.
Abstract:
A display device includes a backlight assembly, a display panel unit, and a control member. The backlight assembly emits a first light and a second light. The display panel unit includes a first display panel and a second display panel, and receives the first light and the second light to display a first image and a second image, respectively. The control member controls an interval between the backlight assembly and the display panel unit. The interval is controlled in a method of positioning the first display panel, thereby emphasizing the display panel unit and diversifying a design of the display device.
