摘要:
A backlight assembly supplies a guided light to a display panel having a main display part on which a main image is selectively displayed, and a sub display part on which a sub image is constantly displayed. The backlight assembly includes a light source and a light guiding unit. The light source generates a light. The light guiding unit includes a light incident surface, a light exiting surface, and a corresponding surface. The light from the light source is incident into the light incident surface. The light exiting surface has a main region and a sub region, the sub region having an optical pattern increasing a luminance of the light. The guided light exits the light exiting surface. The corresponding surface corresponds to the light exiting surface. A luminance uniformity and a luminance when viewed on a plane are increased.

A light guiding plate capable of minimizing a thickness of a backlight assembly and an LCD device, a backlight assembly and an LCD device having the same are provided. The light guiding plate has a light incident surface, a light reflection surface having a plurality of dots for diffusing and reflecting the light emitted from the light incident surface and a light output surface having a predetermined roughness and further diffusing the light diffused and reflected by the light reflection surface. Thus, a conventional diffusion sheet disposed above the light guiding plate may be removed.

A backlight assembly includes a light guide plate including a light incident face, a light exiting face extended from one end portion of the light incident face, and a reflection face extended from another end portion of the light incident face. The reflection face includes a first reflection face extended from another end portion of the light incident face, and a second reflection face horizontally extended from the first reflection face. The backlight assembly additionally includes a light adsorption member disposed adjacent to the reflection face to prevent the light from reflecting. A reflection plate and optical sheets are disposed adjacent to the light guide plate, so that entire thickness of the backlight assembly is reduced. In addition, leakage of the light incident around the third light exiting face is prevented to improve the quality of the image displayed through the LCD device.

An optical film includes a base layer, a resin layer and a plurality of hollow particles. The resin layer is disposed on a surface of the base layer. The hollow particles are disposed in the resin layer. The hollow particles each have an epidermis that defines an inner space of a hollow particle. The hollow particles reflect or transmit light due to a refractive index difference between the epidermis and the inner space.

In a light guide plate and a backlight assembly having the same, the light guide plate includes side surfaces having at least one incident surface into which light is incident, an exit surface on which a first prism pattern for condensing the light and a concavo-convex pattern for diffusing the light are formed, and a reflect surface facing the exit surface and including a second prism pattern formed thereon. Accordingly, the backlight assembly may remove the diffusion and prism sheets therefrom and improve the light efficiency and brightness uniformity.

A method for illuminating a liquid crystal display device, a back-light assembly for performing the same and a liquid crystal display device using the same can improve the front luminance and production yield. Lights from a lamp is incident to a LCD panel side, which are then primarily diffused for a uniformity of the luminous flux of the incident lights. The luminous flux of the primarily diffused lights is condensed with respect to a first orientation component on a plane in parallel with the LCD panel, and then partially and secondarily diffused for extending a view angle of pixels of the LCD panel. After the luminous flux of the secondarily diffused lights is condensed with respect to a second orientation component perpendicular to the first orientation on the parallel plane, the condensed lights are illuminated onto the LCD panel. A diffusion sheet for secondarily diffusing the luminous flux and a condensing sheet for condensing the second orientation component are formed by a single sheet to reduce the manufacturing process of the liquid crystal display device. Also, a defect produced from respective sheets is minimized to enhance the yield.

Disclosed are an LCD and a method of illuminating a liquid crystal layer. A protecting sheet is disposed on a reflection polarization film for enhancing the brightness. The protecting sheet is made of polyethylene terephthalate based material manufactured by an extension process to enhance the brightness, to improve visual angle and to prevent a Moire phenomenon. The LCD and the illumination method of the present invention enable high brightness displaying, color modulation depending on the visual angle and a relatively low manufacturing cost.
