    • The present invention comprises the steps of: (1) forming a first extruded sheet on one surface of a substrate layer by extruding a first resin composition on one surface of the substrate layer and laminating the first resin composition by using a first laminator; and (2) forming a second extruded sheet on the other surface of the substrate layer by extruding a second resin composition on the other side of the substrate layer and laminating the second resin composition by using a second laminator. For step (1), step (2), or both steps, the present invention relates to a method of manufacturing a reflective sheet, configured to form a protrusion pattern on the extruded sheet by using a heated pattern roll. According to the manufacturing method of the present invention, the manufactured reflective sheet has no adherence problems and separation problems of a light guide plate, thereby being advantageously used for the manufacture of a backlight unit.
    • 本发明包括以下步骤:(1)通过在基材层的一个表面上挤出第一树脂组合物并通过使用第一层压机层压第一树脂组合物,在基材层的一个表面上形成第一挤压片材; 和(2)通过在基材层的另一侧挤出第二树脂组合物并通过使用第二层压机层压第二树脂组合物,在基材层的另一个表面上形成第二挤出片材。 对于步骤(1),步骤(2)或两个步骤,本发明涉及一种制造反射片的方法,其被配置为通过使用加热图案辊在挤出的片材上形成突起图案。 根据本发明的制造方法,制造的反射片材没有导光板的粘附问题和分离问题,从而有利地用于制造背光单元。

    • The present invention provides a method for reducing hot spots in a light guide plate, and the light guide plate comprises: an incident surface for receiving light from multiple discrete light sources; an emitting surface for emitting light; a bottom surface in the opposite side of the emitting surface; and an end surface in the opposite side of the incident surface. Furthermore, the direction from the incident surface to the end surface is defined as an Y-axis, the direction which is perpendicular to the Y-axis and is in parallel with the discrete light sources is defined as an X-axis, the emitting surface has multiple thin long grooves which are in parallel with the Y-axis and extended from the incident surface corresponding to Y = 0 to the end surface, and the bottom surface has a core zone extended from a predetermined line corresponding to Y = Y1 to the end surface and a mixing zone extended from Y = 0 to Y = Y1. The method for reducing hot spots in a light guide plate provides the distribution of a set of lenses in the core zone and the distribution of a set of micro-lenses in the mixing zone, wherein the density of the set of micro-lenses is constantly maintained in the X-axis, redirects the light from the discrete light sources toward the Y-axis by selecting the size and density of the micro-lenses, and provides a ratio (L1/L0) that is between 0.9 and 1.1 for any Y >= Y1.
