    • 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.
    • 光学模块包括点光源装置和光学透镜。 点光源装置产生光。 光学透镜包括内曲面和外曲面。 内弯曲表面具有第一大致椭圆形状,其具有基本上垂直于第一长轴的第一长轴和第一短轴。 外曲面具有第二大致椭圆形状,其具有基本上垂直于第一轴线的第二长轴和基本上垂直于第二长轴的第二短轴。 由点光源装置产生的光通过内弯曲表面进入光学透镜,并通过外弯曲表面从光学透镜射出。 因此,可以减少在显示装置中使用的光学模块的数量,以降低其制造成本。
