    • A light guide plate that eliminates haze while obtaining a desired uniformity of luminance to enhance light efficiency. The light guide plate can be used with a backlight unit using the light guide plate and an LCD using the backlight unit. The light guide plate includes an incidence face to allow light emitted from a light source to be incident to the light guide plate, an outgoing face to allow the incident light to exit the light guide plate, a backside face opposite to the outgoing face, and mirror patterns provided at the outgoing face or backside face, and adapted to increase an exiting rate of the light at a low luminance region defined in a vicinity of the light source. The light guide plate is manufactured by a method including a mold machining operation including a prism face milling operation to form, at a mold, a prism face corresponding to a prism face of the light guide plate, and a mirror pattern milling operation to mill the prism face formed at the prism face milling operation using a bit having a predetermined cross-sectional shape, thereby forming mirror patterns at the prism face, and a light guide plate injection-molding operation to mill a molten resin into the mold completely machined at the mold machining operation, thereby injection-molding the light guide plate.
    • 一种在获得所需的亮度均匀性以提高光效率的同时消除雾度的导光板。 导光板可以与使用导光板的背光单元和使用背光单元的LCD一起使用。 导光板包括入射面,以允许从光源发射的光入射到导光板,允许入射光离开导光板的出射面,与出射面相对的背面,以及 设置在出射面或背面的反射镜图案,并且适于增加在限定在光源附近的低亮度区域处的光的退出速率。 导光板通过包括模具加工操作的方法制造,所述模具加工操作包括棱镜面铣削操作,以在模具处形成与导光板的棱镜面相对应的棱镜面,以及镜面铣削操作, 使用具有预定横截面形状的钻头在棱镜面铣削操作中形成的棱镜面,从而在棱镜面形成镜面图案,以及导光板注塑成型操作,将熔融树脂磨制成完全加工的模具 模具加工操作,从而注塑成型导光板。

    • An optical module includes a point light source device and an optical lens. The point light source device generates light. The optical lens includes an inner curved surface and an outer curved surface. The inner curved surface has a first roughly ellipsoidal shape having a first major axis and a first minor axis that is substantially perpendicular to the first major axis. The outer curved surface has a second roughly ellipsoidal shape having a second major axis that is substantially perpendicular to the first axis and the second minor axis that is substantially perpendicular to the second major axis. The light generated by the point light source device enters the optical lens through the inner curved surface and exits from the optical lens through the outer curved surface. Therefore, the number of optical modules used in a display device may be reduced to lower manufacturing cost thereof.
